6Whether the micro-moisture content of blanket gas, density, dew point, pressure, temperature all can play vital effect by reliability service to high-voltage switch gear, are mainly manifested in: as high-voltage switch gear protection gas SF
6Density be lower than a certain numerical value or moisture and surpass certain numerical value, will bring the switch insulation performance to reduce, cause high-voltage breakdown; Produce shelf depreciation because insulating capacity descends near two end electrodes, the time has been grown and has caused the connectivity flashover; Directly affect the break performance of high-voltage switch gear.Therefore, need to be to SF in the high-voltage switch gear GIS equipment
6The parameters such as the micro-moisture content of gas, density detect in real time.
At SF
6In the measurement of gas micro-moisture content, traditional method often adopts the portable micro-water measuring instrument, and its shortcoming is that the portable micro-water measuring instrument can not be to SF
6Gas micro-moisture content carries out online in real time measurement, is merely able to regularly micro-water content be measured, and when micro-water content is measured, need to emit a part of SF in air chamber
6Gas, General Requirements Measuring Time are 5～10 minutes, air release flow value 5L/min, and the air release amount that each detection brings is very large, and the test process more complicated is not easy to operation, and for the less SF of air chamber
6Switch can't adopt the method to detect especially.Simultaneously, owing to from air chamber, emit the SF of a part
6SF in the gas, air chamber
