Abstract

Abstract:

Domestic SF6 gas-insulated electrical equipment often has partial discharge faults, expounds the common causes of partial discharge faults, proposes ultrasonic detection technology for partial discharge of electrical equipment, performs partial discharge fault detection and diagnosis on electrical equipment, and simultaneously applied to power transformers. On line monitoring for was given a test map of the power transformer. The ultrasonic verification of SF6 gas-insulated electrical equipment was carried out. The results showed that the ultrasonic technology can detect the corona discharge and suspension discharge of electrical equipment sensitively.

Key words: gas insulation, partial discharge, ultrasonic, troubleshooting
