System of GIS Flashover Accident Based on Vibration Method

Abstract

Gas-insulated metal enclosed switchgear (GIS) improved the security of EHV transmission applications, which was used more and more widely in recent years in the power system. However, due to the internal insulation defects of the GIS may cause GIS flashover accident, at present, it has studied discharge breakdown by more research for a long time both at home and abroad, which makes reference to the study of fast discharge breakdown caused by flashover, it caused great harm and easy to cause the smart grid paralysis, it should be timely quickly repaired. Based on Piezoelectric film sensors, STM32F3 microcontroller and ZigBee networking technology, this paper designed the GIS flashover quickly locating Scheme based on method of vibration, which achieved the expected flashover fast fault location function, and has a small size, easy operation and low cost advantages.
