关于60335-2-65中16.101章的测试方法
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.The duration of the test is
– 60 s, for frequencies up to twice the rated frequency, or
– 120 × rated frequency/test frequency s, with a minimum of 15 s, for higher frequencies
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？
倍压倍频的测试，输出不接负载的，没有什么影响。在变压器之类的标准里很常见的测试 该测试只针对高压变压器，如果没什么影响，那么该测试有啥意义呢？ 这是一个俗称的“匝间短路”测试，是测量高压变压器内部绝缘是否充分，测试时绕组之间或同一绕组的相邻匝间不应发生击穿。
试验频率提高，试验的电压也同时提高，这样次级才能产生两倍的工作电压。
