摘要
Abstract
Flash faults of ac filters at Gaopo substation of Guizhou-Guangdong 500 kV HVDC transmission system have heppened many times. The mechanism of the flash is analyzed in this paper, and through artificial contamination tests for displaying the voltage change of flash the cause of these flash faults is discovered as follows: The outer insulation of filthy circuit breaker's arc-chute lowered by the inclement weather condition in the high altitude area. Furthermore, countermeasures against the flash of filthy circuit breaker are proposed based on the experimental results.关键词
