摘要
介绍了变频电源的工作原理、试验接线,对现场试验中应该注意的一些突出问题进行了分析,并根据现场经验提出具体解决方法。利用这种加压方式顺利完成了国内第1台三相一体、电压等级500kV、容量720MV·A大型电力变压器局部放电现场测量。这是采用该方式对高电压、大容量变压器局部放电现场测量的一次有益的尝试。
In this paper, the operation principle and the test connecting of frequency conversion power supply are introduced in detail. Some notable problems in field＇ test are analyzed, and the concrete solutions are also put forward according to field practicing. Based on this method, the partial discharge test for the first domestic transformer, three phase in one tank, 500 kV 720 MV·A, is accomplished successfully. This is also a beneficial attempt about partial discharge field measurement of high voltage, huge capacity transformer.
