电源避雷器设计及测试
摘要
随着电子技术的快速发展,集成电路对电压和电流脉冲的敏感程度越来越高,除直击雷影响外,雷电流流经室内金属物引起的感应雷成为电子设备损坏和工作中断新的主要因素.而避雷器对这种感应雷的保护很有效,因此避雷器在现代雷电防护中被广泛应用.
避雷器分为电源避雷器和信号避雷器,本研究就是设计电源避雷器及其测试.根据氧化锌电阻的压敏特性,把电源避雷器并联到保护电路的相线上,并且与PE线相连.当有雷电流或者过电压达到氧化锌电阻的阀值时,氧化锌电阻迅速导通,将雷电流泄放到大地,从而对电路起到保护作用.为了随时知道SPD是否正常工作,本设计专门提供了温度与通断状态的检测接口.
关键词:电源避雷器;温度测试;遥信测试.

《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.
