500kV均压环对绝缘子放电现象的分析与处理

Analysis and Processing of 500 kV insulator grading ring discharge phenomenon

500 kV支柱绝缘子均压环管径取60 mm,通过恰当调整均压环与绝缘子之间的距离,可以降低均压环表面及绝缘子高压端的电场强度,保证正常运行情况下不引起电晕。

500 kV post insulators grading ring diameter taken 60 mm,through adjusted the distance between grading ring and insulator appropriately which could reduce electric field intensity of grading ring and high pressure side of insulator,that ensured normal operation situation do not caused corona.
