西宁变750kV电容式电压互感器误差试验

Error Test of Capacitance Potential Transformer in 750kV Xining Substation

随着高电压、大容量、远距离输电工程的建设,750 kV西宁输变电工程中高压电能计量的准确可靠性成为亟待解决的问题。本文主要介绍了电容式电压互感器的结构,工作原理,以及利用串联谐振电路进行750kV电容式电压互感器的误差试验。

Along with the construction of high voltage, large capacity and long distance transmission engineering, the accuracy and reliability of high voltage energy metering in 750kV Xining substation becomes an urgent problem to be solved. The paper mainly introduces the structure and working principle of capacitance potential transformer, as well as the error test of 750kV capacitance potential transformer using series resonance circuit.
