铁芯电抗器温升仿真分析

Simulation Analysis of Temperature Rise of Iron Core 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中的大容量高压铁芯电抗器为例,通过仿真手段进行其温升分析,验证了电抗器壳体内部油温较为均匀,内、外部结构设计合理。

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,temperature rise analysis was performed through simulation to verify that the oil temperature inside the reactor shell was relatively uniform,The internal and external structure design is reasonable.
