标题: 泄露电流与耐压的问题 [打印本页] 作者: tnq1 时间: 2011-11-19 23:21 标题: 泄露电流与耐压的问题 请各位同志朋友，讨论一下：
1。 为什么有的公司是先打耐压后作泄露电流测试呢？ 标准上有要求吗？
2。 在做耐压测试的时候，耐压仪器的电流到底是2mA /5mA/还是10mA 甚至30mA 呢？作者: lotushell 时间: 2011-11-19 23:21
在IEC标准中应该是先打泄露再打耐压，标准中有明确要求（IEC60335-1）：
13.3：（承接13.2）The appliance is disconnected from the supply and the insulation is immediately subjected to a voltage having a frequency of 50 Hz or 60 Hz for 1 min, in accordance with
IEC 61180-1.
16.3：Immediately after the test of 16.2, the insulation is subjected to a voltage of
substantially sinusoidal waveform having a frequency of 50 Hz or 60 Hz for 1 min. The values
of the test voltage for different types of insulation are given in table 7.
