变频串联谐振试验装置原理说明及使用

我们已知,在回路频率f=1/2π√LC时,回路产生谐振,此时试品上的电压是励磁变高压端输出电压的Q倍。Q为系统品质因素,即电压谐振倍数,一般为几十到一百以上。先通过调节变频电源的输出频率使回路发生串联谐振,再在回路谐振的条件下调节变频电源输出电压使试品电压达到试验值。由于回路的谐振,变频电源较小的输出电压就可在试品CX上产生较高的试验电压。
变频串联谐振试验主要应用于:
1、6kV-500kV高压交联电缆 的交流耐压试验
2、发电机 的交流耐压试验
3、GIS和SF6开关的交流耐压试验
4、6kV-500kV变压器 的工频耐压试验
5、其它电力高压设备如母线,套管,互感器的交流耐压试验。
