2、如果跨接初-次极的元器件的实际工作电压Vrms或Vpeak大於输入电压,则考虑元器件的实际工作电压。作者: dotzuv 时间: 2011-11-23 21:46
请问这个原则是根据什么呢?标准里能找到吗?作者: qinglang 时间: 2011-11-23 21:46
以下引自EN 60950-1-2006 clause 2.10.2 Determination of working voltage
g) The WORKING VOLTAGE between any point in the PRIMARY CIRCUIT and earth, and between any point in the PRIMARY CIRCUIT and a SECONDARY CIRCUIT, shall be assumed to be the greater of the following:
– the RATED VOLTAGE or the upper voltage of the RATED VOLTAGE RANGE; and
– the measured voltage.作者: dotzuv 时间: 2011-11-23 21:47
看来我还是要好好翻翻标准了
