中文摘要：
为了消除静电放电时产生的辐射场对静电放电抑制器测试结果的影响,基于法拉第笼的屏蔽效应、依据国际电工委员会IEC61000-4-2标准和国军标GJB911-1990,利用静电放电模拟器和静电放电电流波形测试装置等设备,测试了某型号聚合物静电放电抑制器的抑制特性。测试结果表明,采用IEC61000-4-2标准规定的电流靶结合法拉第笼的方法,测试静电放电时通过抑制器的电流,能够保证电流波形不失真;而加在抑制器两端的电压,须使用有效带宽足够宽的电压探头配合示波器来测量,同时应尽可能消除静电放电时产生的辐射场对电压探头的影响。
英文摘要：
Electrostatic discharge （ESD） suppressor is the chief way by which the susceptibility to electrostatic discharge of equipment can be decreased. Prior to each application, the ESD suppressor has to be tested in order to evaluate its performances. In the paper, the influence of ESD radiation on the ESD suppressor test was experimentally studied through discharging to the suppressor by ESD simulator. Based on the shielding effectiveness of Faraday cage, the test set-up for ESD circuit waveform composed of ESD simulator, current target, the output cables and oscillograph was made. According to IEC 61000-4-2 and GJB 911-90, using relevant ESD simulator and test set-up for ESD circuit waveform, the suppressing characteristics of a polymer ESD suppressor were tested. The testing resuits show that the measurement, which uses current target and Faraday cage specified in IEC 61000-4-2 to test current on ESD suppressor, is correct; and the voltage wave of suppressor can be tested by oscillograph and voltage probe with an enough efficient bandwidth, and the influences of ESD radiation on voltage probe should be furthest eliminated.
