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.# v5 }/ \5 v& L6 X
The duration of the test is
" d9 M3 G( r! z. j k( t– 60 s, for frequencies up to twice the rated frequency, or9 d* G; [) u5 F! O2 f& c7 ?( b
– 120 × rated frequency/test frequency s, with a minimum of 15 s, for higher frequencies& o4 F) e: J4 p; Y' w6 I/ u
A maximum of one-third of the test voltage is applied and is then rapidly increased without creating transients. At the end of the test, the voltage is decreased in a similar manner to approximately one-third of its full value before switching off."

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?$ E1 X6 p6 _7 J7 H2 Q
