Abstract

The invention discloses an insulating gas treatment device and a control method thereof, and relates to the technical field of insulating gas treatment. The insulating gas treatment device and the control method thereof are invented for solving the problems that when an existing insulating gas treatment device recycles insulating gases, the recycling efficiency is low. The insulating gas treatmentdevice comprises a first connector, a second connector and a recycling branch. The recycling branch comprises a first branch and a second branch. The first branch is connected between the first connector and the second connector, and the first branch is sequentially provided with a first control valve, a pressure reduction valve, a first compressor and a heat exchanger in the direction from the upstream to the downstream. The second branch comprises a plurality of branch paths connected in parallel, one end of each branch path is connected with the part, on the upstream side of the first control valve, of the first branch, the other end of each branch path is connected to the part, between the pressure reduction valve and the first compressor, of the first branch, and each branch path issequentially provided with a second control valve and a vacuum pump in the direction from the upstream to the downstream. The insulating gas treatment device and the control method thereof can be usedfor recycling and other treatment on SF6 and other insulating gases.

Description

technical field [0001] The present invention relates to the technical field of insulating gas treatment, and in particular, to an insulating gas treatment device and a control method thereof. Background technique [0002] In the power industry, insulating gases such as sulfur hexafluoride are widely used in electrical equipment such as Gas Insulated Switchgear (GIS), Gas Insulated Line (GIL) and other electrical equipment for insulation and arc extinguishing . During the operation of electrical equipment, due to the existence of various factors, the insulating gas will inevitably decompose, for example, sulfur hexafluoride (SF 6 ) will decompose under the conditions of electric spark, discharge, etc., and generate sulfurous acid fluoride and hydrofluoric acid, and sulfurous acid fluoride and hydrofluoric acid are highly toxic, which will corrode electrodes and insulating materials, and cause safe operation of operating equipment. Threats, and it is easy to pollute the surr...
