电源产品,耐压测试时,漏电流设置多大?标准中有没详细规定?
请教各位安规同仁:950电源类产品,耐压测试时,漏电流应该设置多大?标准中有没详细规定? 先搜索看看,论坛应该很多人问了啊~~ For equipment powered from an AC MAINS SUPPLY, the test is performed with a voltage equal to
the RATED VOLTAGE of the equipment or to the upper voltage of the RATED VOLTAGE RANGE. For
equipment powered from a DC MAINS SUPPLY, the test is performed with a voltage equal to the
highest nominal voltage of the AC MAINS SUPPLY in the region where the equipment is to be
used, for example, 230 V for Europe or 120 V for North America.
The current flowing in the test circuit of Figure 6A shall not exceed 10 mA. 抱歉剛剛沒傳好... sky0805 发表于 2014-3-18 08:36 static/image/common/back.gif

你这个回答应该是不正确的,耐压测试时关键不是这个漏电流设置多小,而是确认这个设置不影响你测试结果判断。实际说,如果打3000V,你设置漏电流是1mA,实际漏电流是2mA报警了,判断测试失败就很可能误判了。如果设置100mA漏电流,实际漏电流可能是50mA,但是绝缘系统在测试时间内不击穿,没有伴随电压下降的闪络等现象,测试还是通过的。 煩您教導大家何謂正確觀念,並上傳該條文與規範...相信樓主很期待您專業的回應!!!:lol 看标准判断描述
漏电流多少没关系,别超过100mA就行,击穿了就是击穿了,设置一个100mA只是保护你的测试设备。 有时你设置到10mA的话,他会报警,但是你设置到100mA的话是没问题的 原来10MA是有根据的,以前我也认为是只要绝缘不击穿不误判就行!!!
