Abstract

The invention discloses a sulfur hexafluoride (SF6) gas micro water on-line monitoring device of a high-voltage electrical device, a method and a system, wherein the high-voltage electrical device SF6 gas micro water on-line monitoring device comprises a computer data processing system, a gas circulation mechanism and a micro water detector which detects gas in the gas circulation mechanism, wherein the gas circulation mechanism comprises an air cylinder, a piston and a driving device which enables the piston to move back and forth in the air cylinder, the air cylinder is provided with a circulation air vent which is sealed and communicated with a sulfur hexafluoride gas storage chamber which is arranged in a high-voltage electrical device, and the gas circulation mechanism is arranged in a sealed cavity. Gas in the sulfur hexafluoride gas storage chamber arranged in the high-voltage electrical device is circulated to the air cylinder which is arranged outside the high-voltage electrical device through the sealed gas circulation mechanism, thereby enabling humidity of sampling points inside and outside the sulfur hexafluoride gas storage chamber to be capable of rapidly achieving balance, not needing to discharge a large number of SF6 gas by adopting the micro water detector to accurately detect, and being accurate in detection result and safe in performance.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a high-voltage electrical equipment SF 6 Gas micro-water online monitoring device, system and method. 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 ga...
