Abstract: Introduction was made to the detecting principle of ultrasonic partial discharge (PD) detection in gas insulated switchgear (GIS). This paper gave the overall design scheme of ultrasonic 1 000 kV GIS PD on-line detection system, including the hardware and software of the detection system. The simulation test and the characteristic parameters of four conventional types of partial discharge were concluded and the characteristics of ultrasound were summarized. This paper analyzed an actual case of 1 000 kV GIS basin insulator damage in the ultra-high voltage (UHV) substation. The effectiveness of the proposed 1 000 kV GIS ultrasonic testing system was verified.
Key words: ultrasonic; 1 000 kV gas insulated switchgear; partial discharge; system structure
