Problems solved by technology
[0004] The present invention provides an online charging device for SF6 mixed gas in a GIS pipeline to solve the problem that the existing technology cannot judge the position of gas leakage, The mixed gas inflating cannot be realized according to the concentration of the gas leakage position. The invention can realize the inflating of the corresponding component gas after the leakage of the SF6 mixed gas, so as to ensure that the gas concentration of each component is in the process of GIS operation. Meet the operating concentration standard

The invention discloses an online inflation device for SF6 mixed gas in a GIS pipeline. The online inflation device comprises a SF6 gas storage tank, a buffer gas storage tank, a controller, the GIS pipeline and SF6 concentration detection devices; the GIS pipeline is formed by connecting a plurality of GIS tank bodies, and at least two SF6 concentration detection devices are arranged at the connecting position of every two adjacent GIS tank bodies; the SF6 gas storage tank is connected with SF6 gas inlet ends of the GIS tank bodies through a SF6 gas control valve and a first pipeline, and the buffer gas storage tank is connected with buffer gas inlet ends of the GIS tank bodies through a buffer gas control valve and a second pipeline; and data ends of the SF6 concentration detection devices are connected to a signal input end of the controller, and the SF6 gas control valve and the buffer gas control valve are controlled by the controller. According to the online inflation device for the SF6 mixed gas in the GIS pipeline, after the SF6 mixed gas leaks, inflation of gas with corresponding component can be realized.
Description
technical field [0001] The invention relates to a mixed gas online charging device, in particular to a SF in a GIS pipeline 6 Mixed gas online charging device. Background technique [0002] SF 6 Due to its excellent electrical properties, gas is widely used in the power industry, especially high-voltage power equipment such as high-voltage circuit breakers, gas-insulated metal-enclosed switchgear (Gas Insulated Switchgear, GIS). However, SF 6 As a strong greenhouse gas, the gas has 23,900 times the impact on the greenhouse effect than carbon dioxide, so it will have a serious impact on the environment after it leaks into the atmosphere. Existing technology by the SF 6 / N 2 or SF 6 / CO 2 Mixed gas as insulating medium instead of pure SF 6 The gas is used in high-voltage electrical equipment, thereby reducing SF 6 Gas usage. [0003] However, during GIS operation, the SF within the GIS pipeline 6 Gas leakage often occurs in mixed gases. Existing testing equipment ca...
