今天在看IEC60335-1时对比GB4706.1发现脉冲发生器的有效阻抗竟然不一致,到底是笔误还是修改了IEC标准,或者是印刷错误?
标准原文:
14 Transient overvoltages
The impulse test voltage has a no-load wave shape corresponding to the 1,2/50 μs standard
impulse specified in IEC 61180-1. It is supplied from a generator having a conventional output impedance not exceeding 42 Ω. The impulse test voltage is applied three times for each polarity with intervals of at least 1 s.
