Gas supply system and method for gas insulated switchgear

The invention discloses a gas supply system and method for gas insulation combined electrical equipment, and the system comprises a monitoring camera, a data processing module and an electromagnetic control valve, and the data processing module is connected with the monitoring camera and the electromagnetic control valve; the monitoring camera is used for acquiring pressure image data of an SF6 pressure gauge on the gas insulated switchgear; the data processing module is used for judging whether a pressure value corresponding to the pressure image data reaches a preset threshold value or not and generating a judgment result; and the electromagnetic control valve is used for opening a corresponding valve after the SF6 gas cylinder, the gas filling pipeline and the gas insulation combined electrical equipment are connected based on the judgment result. The technical problem that in the prior art, maintenance personnel need to be frequently contacted to supplement air, and consequently large manpower and materia
