Abstract

The invention discloses a GIL insulating gas self-circulation filtering device. In the GIL insulating gas self-circulation filtering device, a gas extraction system is arranged in a GIL bus to extract a first flow of insulating gas, a gas filtering treatment system is communicated with the gas extraction system to treat the insulating gas, a gas inflation system is arranged in the GIL bus to inflate a second flow of insulating gas, the gas inflation system is communicated with the gas filtering treatment system and a gas cylinder for storing insulating gas through a flow meter, and a pressure sensor is arranged on the inner wall of the GIL bus to measure pressure data of the GIL bus.

Description

technical field [0001] The invention relates to the technical field of electric equipment insulation, in particular to a GIL insulating gas self-circulation filter device. Background technique [0002] Gas-insulated transmission line (Gas-Insulated Transmission Line, GIL) is a metal-enclosed long-distance power transmission equipment, using SF6 gas or a mixture of SF6 and N2 as insulation, with low loss, high reliability and environmental friendliness. Advantages, the application in the field of power transmission is becoming more and more extensive. [0003] During the operation of GIL, a series of chemical reactions such as decomposition and combination of the internal insulating gas will occur, resulting in the generation of impurity gases such as H2S, SO2, CO, etc., which will affect the insulation performance and operation safety of the GIL system. At present, the gas composition can be detected by gas chromatography, infrared spectroscopy and other methods to reflect ...
