Main Insulation Electric Field Simulation of EHV Shunt Reactor

目前,特高压电网建设是我国电力系统的发展方向,与之配套的特高压设备发展也势在必行。在国家特高压交流输电工程中并联电抗器发挥着举足轻重的作用,特高压并联电抗器在工作运行中受到各类过电压的影响,主绝缘结构电场仿真计算对于产品的设计起到重要的参考作用。本文仿真使用Ansoft公司的Maxwell软件对特高压并联电抗器的A柱线圈和X柱线圈分别到铁芯饼和旁轭的电场强度进行了计算,计算结果的安全裕度满足工作要求。研究结论对特高压电气产品的仿真分析具有重要的工程实践参考价值。

The current high-voltage grid construction is the direction of the development of the power system in our country,and the development of the high-voltage equipment is also imperative. Shunt reactor in national EHV ac transmission project plays an important role in the operation of the high voltage shunt reactor in work under the influence of all kinds of over-voltage,main insulation structure electric field simulation play an important reference for the design of the product. Simulation using Ansoft company Maxwell software for EHV shunt reactor coil and A column of X column coil respectively to the iron core is bread and yoke of electric field strength was calculated,the calculation results of safety margin meet the job requirements. Conclusion the simulation analysis of high voltage electrical products is of great value in engineering practice.
