Simulation Verification of High Q Value of High-capacity High-voltage Test Reactor

变频串联谐振试验装置是开展高压设备耐压试验的基础,尤其对于长距离大容量超高压电缆而言,需要大容量高压试验电抗器与长距离被试电缆的电容发生串联谐振,以最小电源容量高效完成耐压试验。本文以广州供电局广南—穗西500 kV 22km长距离陆缆耐压试验项目GZHKJXM20160040中的大容量高压试验电抗器为例,对大容量高压试验电抗器进行结构设计与研究,通过仿真手段进行分析,验证了电抗器的电气性能及高Q值设计,满足实际工程要求。

The variable frequency series resonance test device is the basis for carrying out the high-voltage equipment withstand voltage test.Especially for long-distance and large-capacity ultra-high-voltage cables,large-capacity high-voltage test reactors and longdistance tested cables are required to have series resonance in order to The minimum power supply capacity can efficiently complete the withstand voltage test.Taking the large-capacity high-voltage test reactor in the Guangzhou Power Supply Bureau Guangnan-Suixi 500 kV 22km long-distance land cable withstand voltage test project GZHKJXM20160040 as an example,the structural design and research of the large-capacity high-voltage test reactor were analyzed by simulation means,The electrical performance and high Q value design of the reactor are verified to meet the actual engineering requirements.
