摘要/Abstract

摘要： 在进行GB 4706.1的13.3章和16.3章的电气强度试验时,对使用设备耐压仪的高压电源容量要求试验电压≥4000V时,短路电流I_s≥200mA,跳闸电流I_r≥100mA。而JJG 795检定规程里只有对I_r检定,没有对I_s检定,故实验室需要掌握一种验证I_s的方法。本文从耐压仪工作原理出发理解I_r和I_s,然后分别介绍了间接验证和直接测量I_s的方法。

Abstract: When conducting the electrical strength test of Chapters 13.3 and 16.3 of IEC 60335-1, the short-circuit and release energy requirements for the high-voltage power supply capacity of the equipment when the test voltage is≥4000V, the short-circuit current I_s≥200mA, trip current I_r≥100mA. In the JJG 795 verification procedure, only I_r is verified, and I_s is not verified, so the laboratory needs to master a method of verifying I_s. This article understands I_r and I_sfrom the working principle of the high voltage tester, and then introduces the methods of indirect verification and direct measurement of I_s.
