当防直击雷的人工接地体距建筑物出入口或人行道小于3m时可采取哪些措施?

其实主要是看雷的带电量,不论哪种形式的雷,带电量大的威力就大.

《Design and Test on Power Source Arresters》
Abstract
With the rapid development of electronic technology,the sensitivity of integrated circuits influenced by voltage and current pulse is getting higher and higher,apart from the influence of the direct stroke,the induction stroke caused by the lightning current flowing through the indoor metals becomes the new major factor which damages the electronic equipments and disrupts our works.However,the protection of a arrester is quite effective to the induction stroke,so that the arresters have been widely used in modern lightning protection.
The arrestor can be divided into two types of power source arrester and signal arrester.This paper is researching on the design and test for a power source arrester.Based on the voltage-sensitive characteristic of zinc oxide resistor,we parallel the power source arresters with the protection phrase line,and connect it to the PE lines.When a lightning current or over-voltage reaches the threshold value of the zinc oxide resistor,the resistance of the zinc oxide quickly breakover and bleed the lightning current to the earth,thus protecting the circuit.in order to know whether the SPD is in work any time,this paper also provides a design of the interface detecting the status of the temperature and the on-off state.
Key words:power source arresters; temperature test; remote signal test.

The designing and testing of power lightning arrester
Abstract
With the rapid development of electronic technology,the sensitive degree of voltage and current pulse for integrated circuits is getting higher and higher,Apart from the impact of direct lightning strike,the lightning current flowing through the interior metal mine causes the indirect lightning ,which is a new major factors of electronic equipment damage and disruption .The arrester on the prevention of this sensor is very effective,so in the modern lightning protection surge arresters have been widely used.
Lightning arresters are divided into power lightning arresters and signal lightning arresters .this study is to design and test the power lightning arrester.Based on the voltage-sensitive characteristics of zinc oxide resistance ,make the power lightning arresters parallel with the protected circuit ,and connect with the PE line .When a lightning current or over-voltage reach the threshold of zinc oxide resistance,the zinc oxide resistance conducts quickly,and discharges the flow of the lightning on the earth,thus protects the circuit.In order to know whether SPD is working at any time ,the study specially provides the detection interface of the temperature and on-off state.
Key words:power lightning arrester; temperature testing; remote communication testing.
