Abstract

The invention discloses a supersonic online detection system of a 1000kV GIS, and relates to the field of electronic technology. Supersonic probes are mounted on a casing or basin-type insulator of the 1000kV GIS, and collect internal discharge signals of the GIS in real time, the signals are transmitted to an optical relay station via fibers and converted into electric signals, the electric signals are amplified, processed and stored, and then analyzed by a host computer, and display, printing and teletransmission functions are provided. The supersonic online detection system of the 1000kV GIS can be applied to the field in detecting partial discharge defect of the common 1000kV GIS, the problems as inaccurate positioning and slow response of a traditional detection method are effectively solved, and the system of the invention is worthy of popularization and use widely.

Description

technical field [0001] The invention relates to the technical field of a partial discharge detection method for UHV equipment, in particular to a 1000kV GIS ultrasonic on-line detection system. Background technique [0002] Partial discharge is a discharge phenomenon that occurs in a local area of ​​a metal-enclosed gas-insulated combined electrical appliance (GIS). If partial discharge exists for a long time, it will cause insulation damage, resulting in a penetrating breakdown inside the GIS. At present, the GIS partial discharge ultrasonic detection device widely used in the power grid can realize the detection and accurate positioning of internal discharge during GIS operation, and plays an important role in timely discovering hidden dangers of equipment. [0003] However, there is currently a lack of necessary technical means to realize a real-time monitoring system for the partial discharge of GIS equipment, which is very unfavorable to the evaluation of the actual ope...
