并联电容补偿装置电抗器过电压保护

Overvoltage Protection of Reactor for Parallel Capacitance Compensation Device

针对电容补偿装置在运行中电抗器着火,既有保护装置不起作用的现状,通过实测电抗器运行中的波形分析,阐述牵引负荷产生的谐波是电抗器绝缘破坏的主要原因,并提出改进措施。

For the status that the protection device is not functioning during the fire is caught on the reactor when the reactance compensation device is in operating, the paper illustrates that the destruction of the reactor insulation is mainly caused by the harmonics produced by the traction load by analyzing the waveforrn tested from the actual operation of the reactor, and puts forward the improving measures.
