500kV支柱绝缘子防污闪措施的试验研究

Testing Research of the Measure for Proventing form Pollution Flashover of 500kV Support Insulators

500kV支柱绝缘子由于防污闪性能差，急需研究行之有效的施措，提高防污闪性能．介绍通过人工污秽试验和现场试运行，提出500kV支柱绝缘子的防污闪措施，对确保电网的安全运行有重要意义．

Bccausc of the low ability of anh-contamination nashovcr, it is nccessary to research an effcctive mcasures to improve this ability of 500kV rod insulators. In this papcr a kind of mcasure of prcventing form contamination flashovcr of 500kV rod insulators is presentcd by mannual contamination tcst and site operation. It is important for the safe operation of powcr network.
