1.- Electrical Insulation Test
500 V DC will be applied for 1 minute between any pole and accessible
metal part1. Insulation value will be up to 2 MΩ
2.- Dielectric Strength
3000 V AC will be applied between any pole and accessible metal part, for
1 minute. No flashover or breakdown shall occur during the test.
3.- Leakage Current
1,06 times rated voltage ( 1,06 x 230 V = 244 V ) will be applied between
any pole and metal part for 5 s.
Leakage current will be lower than 0,75 mA.
现在就是第一个电气绝缘强度是什么测试，是不是包含在打高压里面？作者: ljhclxlxf 时间: 2010-11-21 13:17
1. 测试绝缘强度的, 是有专门仪器的, 我们通常要求是10MΩ, 一般都能过.你的是从哪份标准中拷出来的, 60335里面是没有这个要求的.日本的小家电标准是不要求打高压,只测试绝缘强度的.
2. 就是打高压了.
绝缘强度和打高压是两回事来的.作者: 9000 时间: 2010-11-21 13:17
The first one is for insulation resistance test, and the second one is high voltage test, normally, these two tests can be finished on one test equipment, anyway there is also special use test equipment for the insulation resistance test... 作者: 9000 时间: 2010-11-21 13:17
第一个说的是绝缘电阻测试 作者: 832000 时间: 2010-11-21 13:17
分别是绝缘电阻，打耐压，泄漏电流三个测试。作者: xar7879 时间: 2010-11-21 13:17
Leakage current test should be performed on special tester, not on Dielectric Strength Tester.
