60335-2-65中16.101章的标准上提到“Twice the working voltage is induced in the secondary winding of the transformer by applying a sinusoidal voltage having a frequency higher than rated frequency to the primary terminals.% s9 r" Y/ w& ^* K

有没有人实际操作过该测试?按照标准要求,是否在变压器初级施加一高于额定频率的正弦波电压,使次级产生两倍的工作电压。问题是初级施加高于额定频率的正弦波电压,次级是否可以产生两倍的工作电压?. o1 q2 B& B+ g+ x; w+ ` o4 m
