谁能帮我找份“光纤传感是温度传感器”的英文资料呀,急!!!

Temperature Sensor Types Big differences exist between different temperature sensor or temperature measurement device types. Using one perspective, they can be simply classified into two groups, contact and non-contact. The two links below take you to descriptive pages on each type with a breakdown by more specific, detailed types under that simple, first breakout. There are also vendors of each sensor type, some vendors sell more than one type and some sell nearly all types, but not always all brands. There are differences between brands and the differneces are most evident among those device types for which there are few if any recognized standards. Start your search either for a specific temperature measurement device type or go to the vendor page index and you can access the vendors of specific types from there. Both contact and non-contact sensors require some assumptions and inferences in use to measure temperature. Many, many well-known uses of these sensors are very straightforward and few, if any, assumptions are required. Other uses require some careful analysis to determine the controlling aspects of influencing factors that can make the apparent temperature quite different from the indicated temperature. Tell your new product and application stories at The Temperature Community website: www.tempsensor.net or feedback to us and we"ll consider adding it here with your byline!Remember the truism that all sensor have errors in their readings - all the time. One key secret to high quality measurement results is to have confidence in the error estimates. Neglecting to make a careful error analysis can result in error much larger than the assumed values. It is worth noting that all competent error analyses start with the uncertainties assigned to the traceable calibration of the sensor itself. Without traceable calibration, one is forced to make assumptions. (You know what the word ass|u|me means, we hope.) Without traceable measurements, the numerical values of results will always be questionable and hardly worth the effort, and cost. It most often pays to get started on the right path to technically sound measurements by beginning with some understanding of the options involved in selecting a temperature measurement device and then in obtaining one that meets the expected conditions and standards, is calibrated and that the calibration is traceable to either a fundamental standard (e.g. the triple point of water) or a national standard. See our calibration and standards pages for more details on each aspect of sound measurement practice. Contact SensorsContact temperature sensors measure their own temperature. One infers the temperature of the object to which the sensor is in contact by assuming or knowing that the two are in thermal equilibrium, that is, there is no heat flow between them.Noncontact SensorsMost commercial and scientific noncontact temperature sensors measure the thermal radiant power of the Infrared or Optical radiation that they receive from a known or calculated area on its surface, or a known or calculated volume within it (in those cases where the obect is semitransparent within the measuring wavelength passbad of the sensor). One then infers the temperature of an object from which the radiant power is assumed to be emitted (some may be reflected rather than emitted). Sometimes the inference requires a correction for the spectral emissivity (NB: the two words, spectral & emissivity, are used together in correcting IR Thermometer readings -the "emissivity", unspecified, is a big trap which even some of the suppliers of devices and calibration equipment fall into unwittingly for a variety of reason about which one can only speculate ) of the object being measured. Knowing how and when to apply a spectral emissivity correction is part of the inference, too, and can introduce significant errors if not done correctly. See our Trip down the E-missivity Trail to help you understand that aspect a little better. Dewpoint Temperature -- Humidity--Although this area is in reality just an application of temperature sensors and other sensors, it grew out of temperature measurements. Remember the old style humidity indicators that consisted of two little glass thermometers, the wet and dry bulb thermometers with a little look up table that told you the humidity, both absolute and relative? Have a look, it"s a very important area in terms of human comfort, food safety and energy conservation and efficiency in thermal processes.Thermal Imaging The special world of thermography and thermal images includes the temperature-measuring kind of thermal imagers called "Radiomatic", by those in the business, and "Quantitative" by those mostly in R&Dwith thermal imaging. Then, too, there are those who call it "Thermology" when it applies to measurements made on the human body and "Medical Thermography" by still others, some even in the same business. Users of infrared thermal imaging have many options in cameras both with and without temperature scales or temperature indication. It seems really odd to have all these different names kicking about, when they all refer to the same basic technology. The names seem to differ only by application area. In reality, they all work because of the same Law of Physics, called Planck"s Law. That"s the same law that describes how IR thermometers, optical pyrometers, radiation thermometers and infrared intrusion or people detectors work (note the common trait of multiple names).The only thing that an IR thermal imager of any denomination really does is take the output from an infrared detector, or plethera of detectors, and presents a 2-D scan of the infrared intensity distribution in the field of view of an optical system. These devices could be called by one common name. The devices that provide temperature information, probably more than any other type of device should be called Infrared Imagers, or Thermal Infrared Imagers or, simply, Thermal Imagers. Go to our thermal imaging section by clicking the above underlined link and learn more than you ever thought you would want to know about the subject.--------------------------------------------------------------------------------Click here to find out about ISPoT! The Applications page can lead you to many well-known solutions or examples, possibly similar to the one you are trying to solve. Why re-invent the wheel?Two excellent reference by Baker et al. are listed in the References page and worth reading to get an idea of the complexities that can arise, how to test and get around them. They are older books and while the technology of the equipment has changed, especially the electronics, the measurement fundamentals have not. Heat flow is heat flow and thermal radiation physics was unified theoretically by Max Planck more than 100 years ago!A great many temperature measurement problems are solved through a good understanding of the heat flow involved in a specific measurement situation. Surface temperature problems with contact sensors are often best solved in many cases through the use of non-contact sensor. They are in use in many industrial plants worldwide in great numbers. The above reference texts provide interesting analyses of the likely errors making contact temperature measurements of surfaces, both stationary and moving surfaces. We have not seen any recent analyses with as much detail! Good luck and best wishes. 参考:http://www.temperatures.com/sensors.htmlhttp://www.ruhr-uni-bochum.de/rubitec/Schweiger_engl.pdf

变压器 设立关键词 要设哪些关键词?power transformer 还有些什么?

选择网站关键词时要根据网站发展目标(网站是做品牌还是追求即时成单率,公司主要销售区域及目标开发市场区域)、自己产品优势及行业普遍情况(竞争对手情况)、网友搜索习惯、相关关键词热度综合决定,关键词不能太热门也不能太冷门,太热门的关键词竞争者多,往往还有许多竞价排名企业,很难做上去,太冷门的关键词做上去没有人搜索,不符合网友搜索习惯的关键词做上去往往也只是“看上去很美”,起不到应有的效果。比如朋友的变压器网站,如果是某一品牌或某几种变压器的全国总代理的话,那么网站关键词就应该设立为“X品牌变压器”、“Y品牌变压器”,如果主要针对某个省(比如云南省——经营各种变压器,那么网站关键词可以设置为“云南变压器”、“昆明变压器”、“云南变压器销售”、“云南变压器大全”等等。并且,除了网站关键词设立之外,每个网页都要设置单独的关键词,另外建议朋友再仔细研究流量统计(如CNZZ),并结合本行业销售情况与网友搜索习惯,并根据企业自身情况,对一些企业有竞争力的产品上做好“长尾关键词”(如“云南变压器哪里买”、“云南变压器价格”)设置工作,并根据这些“长尾关键词”组织文章,设置锚文本内链,并有针对性地加强这些“长尾关键词”的锚文本外链工作,这样就能较好地解决将一些自己企业网站关键词做不上去的问题,并可以有效提升网站权重。但必须提醒朋友的是,关键词排名还要靠内容为王,朋友你的网站必须有更多与关键词息息相关的原创内容才行,只有网站有了更多的原创内容(注意网站内链建设尤其是锚文本内链的建设)之后,必须考虑网站外链(锚文本外链)的的规律性建设,整个网站的搜索引擎权重才可能不断提升,网站的关键词排名才可能做上去,而且做上去之后不容易下滑太快。

什么是功率因数?

1、变压器本身对功率因数没有具体要求。电力行业规定0.95以上。 2、功率因数(Power Factor)的大小与电路的负荷性质有关, 如白炽灯泡、电阻炉等电阻负荷的功率因数为1,一般具有电感性负载的电路功率因数都小于1。功率因数是电力系统的一个重要的技术数据。功率因数是衡量电气设备效率高低的一个系数。功率因数低,说明电路用于交变磁场转换的无功功率大, 从而降低了设备的利用率,增加了线路供电损失。 3、变压器(Transformer)是利用电磁感应的原理来改变交流电压的装置,主要构件是初级线圈、次级线圈和铁芯(磁芯)。主要功能有:电压变换、电流变换、阻抗变换、隔离、稳压(磁饱和变压器)等。按用途可以分为:电力变压器和特殊变压器(电炉变、整流变、工频试验变压器、调压器、矿用变、音频变压器、中频变压器、高频变压器、冲击变压器、仪用变压器、电子变压器、电抗器、互感器等)。电路符号常用T当作编号的开头.例: T01, T201等。

pandapower最优潮流计算tutorial

This is an introduction into the usage of the pandapower optimal power flow. It shows how to set the constraints and the cost factors into the pandapower element tables. 该notebook主要是介绍pandapower最优潮流计算的使用。它展示了如何将约束和成本因子设置进入pandapower的元件列表。 We use the following four bus example network for this tutorial: 我们的教程使用下图的4节点示例网络: We first create this network in pandapower: 我们首先在pandapower中创建网络: We specify the same costs for the power at the external grid and all generators to minimize the overall power feed in. This equals an overall loss minimization: 我们特别指出外部电网和所有的发电机具有相同的电能成本,并最小化总的电能供应。这相当于整体网损的最小化。 pp.create_polynomial_cost()为元件的多项式成本创建一个条目,返回已经创建的成本条目的ID We run an OPF: 我们运行一个最优潮流计算: let"s check the results: 让我们看下结果: Since all costs were specified the same, the OPF minimizes overall power generation, which is equal to a loss minimization in the network. The loads at buses 3 and 4 are supplied by generators at the same bus, the load at Bus 2 is provided by a combination of the other generators so that the power transmission leads to minimal losses. 因为所有的成本都看成相同的,最优潮流计算最小化总的发电量后的结果和网络的损失最小化结果相同。母线3和母线4的负荷由各自母线上的发电机供应,而母线2上的负荷是由其他发电机联合供应因此电能的传输达到了最小的损失。 Let"s now assign individual costs to each generator. 现在给每台发电机赋予各自的发电成本。 We assign a cost of 10 ct/kW for the external grid, 15 ct/kw for the generator g0 and 12 ct/kw for generator g1: 我们给外部电网赋予10ct/kW的成本,发电机g0赋予15ct/kW的成本以及发电机g1赋予12ct/kW的成本: And now run an OPF: 现在运行最优潮流运算: We can see that all active power is provided by the external grid. This makes sense, because the external grid has the lowest cost of all generators and we did not define any constraints. 我们可以看出所有的有功都是由外部电网提供。这是合理的,因为外部电网拥有最低的发电成本,而且我们没有定义任何的约束。 The dispatch costs are given in net.res_cost: dispatch成本可以由net.res_cost给出: Since all active power comes from the external grid and subsequently flows through the transformer, the transformer is overloaded with a loading of about 145%: 因为所有的有功功率都来自与外部电网,接着潮流流过了变压器,变压器过载运行,负载约为145%: We now limit the transformer loading to 50%: 现在设置变压器的负载约束为50%: (the max_loading_percent parameter can also be specified directly when creating the transformer) and run the OPF: (max_loading_percent参数也可以在创建变压器时直接指定) 然后运行最优潮流计算: We can see that the transformer complies with the maximum loading: 我们可以看到变压器以最大负荷运行: And power generation is now split between the external grid and generator 1 (which is the second cheapest generation unit): 现在有功功率的产生主要来自于外部电网和发电机g1(g1是发电成本第二低的发电机组) This comes of course with an increase in dispatch costs: 这样的结果就导致了dispatch成本的上升: We now look at the line loadings: 我们现在关注于线路负载: and run the OPF with a 50% loading constraint: 然后在线路50%负载水平条件下运行最优潮流计算: Now the line loading constraint is complied with: 现在线路的负载约束编译后: And all generators are involved in supplying the loads: 所有的发电机都开始供应负荷: This of course comes with a once again rising dispatch cost: 这导致了dispatch成本又一次的提升: Finally, we have a look at the bus voltage: 最后,我们在关注一下电压: and constrain it: 加以约束,并运行最优潮流计算: We can see that all voltages are within the voltage band: And all generators are once again involved in supplying the loads: 所有的发电机又一次都参与了负荷的供应: This of course comes once again with rising dispatch costs: 又一次导致了dipatch成本的提升: pandapower also provides the possibility of running a DC Optimal Power Flow: pandapower也可以提供了运行直流最优潮流计算的可能: Since voltage magnitudes are not included in the DC power flow formulation, voltage constraints canot be considered in the DC OPF: 因为直流潮流公式中不考虑电压幅值,所以在直流潮流计算中并不考虑电压约束: Line and transformer loading limits are however complied with: 线路和变压器负载限制编译后为: As are generator limits: 发电机限制为: The cost function is the same for the linearized OPF as for the non-linear one: 线性最优潮流计算和非线性潮流计算的成本函数一致: Piecewise linear cost functions The OPF also offers us piecewise linear cost functions. Let us first check the actual cost function setup: 分段线性成本函数 最优潮流九三也提供了分段线性成本函数。我们首先看一下实际的成本函数设置: An element can either have polynomial costs or piecewise linear costs at the same time. So let us first delete the polynomial costs in order to avoid confusion and errors: 一个元件的成本函数只能是多项式或者分段线性中的一种。因此,让我们首先删除多项式成本函数,以免产生困惑和错误: The results above have been produced with polynomial cost functions, that were linear. Let"s try to reproduce the results using piecewise linear cost functions. Note: The cost functions need to have the same gradient! 上面的计算结果是采用多项式成本函数计算的,是线性的。现在我们使用分段线性函数重新计算结果。 需要强调的是:成本函数需要拥有相同的梯度! What we forgot is that the piecewise linear function should be defined for the whole range of the generator. The range is determined by p_max and p_min. Let"s check: 额...错误信息是ValueError: Cost function must be defined for whole power range of the generator,让我们检查一下: We try again: 我们再试一下: An external grid usually has no operational limits, but this is a problem for the OPF: 外部电网通常没有运行限制,但这是OPF的一个问题: So we set imaginary constraints, that we can choose very broad: 因此,我们虚构一个约束,将这个约束的范围设置的很广: Let us check the results from the previous OPF again! 让我们再看一下之前的OPF运行结果: We run the same OPF now with different cost function setup. We should get the exact same results: 我们运行了相同的OPF但是采用不同的成本函数,我们应该获得完全相同的结果:

输配电系统 英语作文

Introduction of Electric power Transmission and Distribution:For economical generation of power large generating stations are used. Capacities of individual generating sets have gone up recently. Generating sets in the range of 10 MW, 210 MW and 500 MW are being manufactured in many countries. Generating station are now not necessarily located at load centers. In fact other factors like availability of fuel and water play more dominating role in the selection of sites for thermal stations. Hydro stations are obviously located only at the sites where water is available at sufficient head. A vast network of transmission system has been created so that power generated at one station may be fed to grid system and may be distributed over large areas and number of states. The transmission and distribution system comprises a network of three-phase circuits with transforming and or switching substations at the various junctions. The parts of a transmission and distribution network maybe grouped as given below.Electric power TRANSMISSION:Several generating stations can be inter connected. The main advantages are :(i) reduction in the number of spare plants required as one station can assist the other at the time of emergency.(ii) during light loads one station or some generators can be shut off, thus affecting operational economy.Primary electric power transmission:High voltages of the order of 66 kV 132 kV 220 kV and 400 kV are used for transmitting power by 3 phase 3 wire overhead system. This is supplied to substations usually at the out skirts of major distribution center or city.Secondary electric power transmission:The primary voltage is reduced to low values of the order of 3.3 kV, 11 kV or 33 kV for secondary transmission.Primary electric power distribution:The transmission lines or inner connectors terminate at large main substations from which the power is distributed to small secondary substations scattered throughout the load area. The voltage may range from 11 kV to 132 kV.Secondary electric power distribution:This consists of the low-voltage network laid along the streets, localities and over the rural areas. From these sources connections to individual customers are provided. The circuit used for this purpose is 3 phase 4 wire, 440 V/220 V from which either 3 phase 440 V or single phase 220 V supply to the consumers may be provided.System layout of electric power transmission and distribution:From the power stations PS, emanate 3 phase feeder supplying secondary distributions substations located at points throughout the supply area. The normal voltages are 132 kV, 33 kV and 11 kV.COMPARISON OF AC AND DC power TRANSMISSION:(A) Advantages of DC electric power transmission:1. It requires only two conductors.2. There is no problem of inductance, capacitance and phase displacement which is common in ac transmission.3. For the same load and sending end voltage, the voltage drop in dc transmission lines is less than that in ac transmission.4. As there is no skin effect on conductors, therefore entire cross-section of conductor is usefully utilized thereby affecting saving in material.5. For the same value of voltage insulating materials on dc lines experience less stress as compared to those on ac transmission lines.6. A dc line has less corona loss and reduced interference with communication circuits.7. There is no problem of system instability so common in ac transmission.Disadvantages of DC transmission:1. Generation of power at high dc voltages is difficult due to commutation problems and cannot be usefully utilized at Consumer ends.2. Step up or step-down transformation of dc voltages is not possible in equipment like transformer.(B) Advantages of AC electric power Transmission:1. Power can be generated at high voltages as there is no commutation problem.2. Ac voltages can be conveniently stepped up or stepped down.3. High voltage transmission of ac power reduces losses.Disadvantages of AC electric power transmission:1. Problems of inductances and capacitances exist in transmission lines2. Due to skin effect, more copper is required.3. Construction of AC transmission lines is more complicated as well as costly4. Effective resistance of ac transmission lines is increased due to skin effect.来源:http://www.electricalquizzes.com/electric-transmission-distribution/electric-transmission-distribution望采纳

变压器功率因数低的意义有哪些?

1、变压器本身对功率因数没有具体要求。电力行业规定0.95以上。 2、功率因数(Power Factor)的大小与电路的负荷性质有关, 如白炽灯泡、电阻炉等电阻负荷的功率因数为1,一般具有电感性负载的电路功率因数都小于1。功率因数是电力系统的一个重要的技术数据。功率因数是衡量电气设备效率高低的一个系数。功率因数低,说明电路用于交变磁场转换的无功功率大, 从而降低了设备的利用率,增加了线路供电损失。 3、变压器(Transformer)是利用电磁感应的原理来改变交流电压的装置,主要构件是初级线圈、次级线圈和铁芯(磁芯)。主要功能有:电压变换、电流变换、阻抗变换、隔离、稳压(磁饱和变压器)等。按用途可以分为:电力变压器和特殊变压器(电炉变、整流变、工频试验变压器、调压器、矿用变、音频变压器、中频变压器、高频变压器、冲击变压器、仪用变压器、电子变压器、电抗器、互感器等)。电路符号常用T当作编号的开头.例: T01, T201等。

隔离牛(isolating transformer)

隔离牛(isolating trformer) 隔离牛就是把外界电源与最终用电部份隔离 并提供与输入电源相同的电源供应 厕所用插座 便是220v:220v的隔离牛 原理是火牛的初级与次级是两红不同的线圈 而比例是1:1 隔离牛你可以用 角-星 或 角 - 角 或 星 - 角 接法 其中星角可以阻隔外界的hormonic进入 影响你的系统 角角 只适合平衡三相380伏特用电 时常跳制(漏电跳制RCCD) 除了真正漏电 harmonic跟接触不良产生火花也会有影响 我想找一个专家的电力工程人员 比较能帮你解决问题(当然不是指一般电工) 2007-10-30 10:11:39 补充: 顺带一提 harmonic(谐波)是会影响漏电断路器的寿命 特别是美国牌子的square D 那只是名符其实的(傻瓜D) 很多时因为脚软而跳掣(即是未到达预定数值已经跳脱) 如果问题持续而且只是个别漏电断路器跳掣可以先换掉该漏电断路器 MG这个牌子会比较好 你的问题除了在电脑房会发生之外 一些大些写字楼也会出现 其中另一个解决方法是加装多一个配电箱 减少同一漏电断路器供应插座的数量 你部机(用三相three phase) 时常跳制(漏电跳制RCCD),肯定系漏电,唔知你部系乜嘢机,如果系电脑机正要用隔离牛(isolating trformer),因为有开关式电源变压器 Switching Mode Power Supply unit,呢架嘢多少都会漏电既,仲有千祈唔好用直流高电压绝缘测试(insulating test),会烧机架,如果唔系Switching Mode Power Supply unit,就用直流高电压绝缘测试 (500V / 1000V insulating test),好快你就可以揾到问题既所在,医病要断根,一次过搞掂。
