Abstract

The invention discloses SF6 gas monitoring device, method and system of high-voltage electrical equipment. The device comprises a gas circulating mechanism and a micro-water detector for detecting gas in the gas circulating mechanism, wherein the gas circulating mechanism comprises a gas storage tank and a heating device for heating the gas storage tank; and the gas storage tank is provided with a circulating vent hole which is in sealed communication with a sulfur hexafluoride gas storage chamber in the high-voltage electrical equipment. According to the SF6 gas monitoring device, method and system, the sealed gas circulating mechanism is used for circulating the gas in the sulfur hexafluoride gas storage chamber in the high-voltage electrical equipment to the gas storage tank outside the high-voltage electrical equipment, so that the humidity of sampling points inside and outside the sulfur hexafluoride gas storage chamber can be rapidly balanced; and accurate measurement is carried out by the micro-water detector and a lot of SF6 gas does not need to be exhausted, so that a detection result is accurate and the performance is safe.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a SF 6 Gas monitoring devices, methods and systems. Background technique [0002] Currently, SF 6 (Sulfur hexafluoride) electrical equipment has been widely used in the power sector, industrial and mining enterprises, and promoted the rapid development of the power industry. In recent years, with the rapid economic development, the capacity of my country's power system has expanded rapidly, and SF 6 The amount of electrical equipment is increasing. SF 6 The role of gas in high-voltage electrical equipment is arc extinguishing and insulation, and SF in high-voltage electrical equipment 6 If the micro-water content of the gas exceeds the standard and the density decreases, it will seriously affect the SF 6 Safe operation of high-voltage electrical equipment: 1) With the participation of some metal objects, SF 6 The gas can undergo hydrolysis reaction with water at a ...
