Simulative discharger for GIS (gas-insulated switchgear) partial discharge detection

Abstract

The invention relates to the technical field of GIS (gas-insulated switchgear) partial discharge detection, in particular to a simulative discharger for GIS partial discharge detection. The simulative discharger for GIS partial discharge detection is characterized in that the simulative discharger comprises a self-excited oscillation circuit, a high voltage rectification and energy accumulation circuit, a booster circuit, a discharge gap circuit and a discharge loop, the self-excited oscillation circuit is respectively connected with a 1.5V direct-current power supply, the discharge loop and the high voltage rectification and energy accumulation circuit, and the booster circuit is respectively connected with the discharge loop, the discharge gap circuit and the high voltage rectification and energy accumulation circuit. Compared with the prior art, the simulative discharger for GIS partial discharge detection has the advantage that the simulative discharger can judge whether GIS partial discharge detection equipment is in the fault state or not at any time, consequently, the GIS partial discharge detection equipment can operate in a stable state, the reliability of the result of measuring a detected object by the GIS partial discharge detection equipment is guaranteed, and the purpose of guaranteeing the safe and reliable operation of the detection equipment is achieved.

Description

technical field [0001] The invention relates to the technical field of GIS partial discharge detection, in particular to an analog discharger for GIS partial discharge detection. Background technique [0002] With the acceleration of my country's economic development and urbanization, the demand for GIS (Sulphur Hexafluoride Enclosed Combined Appliance) equipment has increased sharply. Due to the fact that there are many manufacturers of GIS (Sulphur Hexafluoride Enclosed Combined Electrical Appliances) at present, the manufacturing levels are different, and the product quality is highly dispersed. Moreover, the GIS (Sulfur Hexafluoride Closed Combined Electrical Appliance) put into operation in my country in the early stage has entered the middle and late stages of its life, and the operation of equipment has entered a period of frequent failures; The probability and risk of failure of closed combination electrical equipment are also very high, which creates a huge contradi...

Problems solved by technology

However, the existing portable partial discharge detection system based on the UHF detection principle is difficult to judge whether there is a fault during use due to different storage conditions and other external factors, and the state of the detection equipment is uncertain; When testing the detection equipment to detect GIS (Sulphur Hexafluoride Enclosed Combined Electrical Appliance) equipment, if no partial discharge signal is detected, it cannot be determined whether the GIS (Sulphur Hexafluoride Enclosed Combined Electrical Appliance) equipment itself has no partial discharge or whether it is Due to the failure of the partial discharge detection equipment due to improper storage, the partial discharge signal was not detected, resulting in a large hidden danger
