小型组合式电抗器在500 kV电压互感器现场校验中的应用

介绍了一套更符合现场试验特点的升压系统.该系统基于串联谐振升压原理,通过固定高压电抗器、积木式高压可调电抗器的各种组合方式实现不同电容量的500 kV电压互感器的串联谐振升压.其方式更轻便、更灵活.

A voltage -boosting system which is more suitable for field calibration is presented. This system is based on the principle of voltage - boosting via series resonant. With various combinations of fixed high - voltage reactors and building - block high - voltage tunable reactors, the series resonant voltage - boosting of 500 kV voltage transformer for various capacitance can be achieved, which is more portable and more flexible.
