Abstract

The invention discloses an electrical intelligent SF6 gas charging device. The electrical intelligent SF6 gas charging device comprises an environment monitoring device, a rated pressure lock alarming device, an automatic gas charging pipeline purifying device, a bolt-clamping-type gas charging pipe, a gas pressure meter, a pressure release valve and a multifunctional connector. The electrical intelligent SF6 gas charging device can automatically distinguish whether the environment meets requirement and automatically purify the gas charging pipeline during gas charging, so that the SF6 gas purity and the micro-water content are qualified; the rated pressure lock alarming function also solves the SF6 gas 'over-charge' problem; moreover, the gas charge pipe is dismounted rapidly, and the gas charging efficiency and the gas charging quality are improved.

Description

technical field [0001] The invention relates to an intelligent SF6 inflatable device for electrical equipment, which can monitor the inflated environment in real time, automatically purify the inflated pipe, quickly disconnect and connect the inflated pipe, and lock and alarm the rated pressure when in use. Background technique [0002] The power industry standard stipulates that the SF6 gas pressure of power equipment in normal operation must meet the rated pressure; when performing SF6 inflation operation, the ambient temperature must be ≥ 0 °C and the humidity ≤ 80%; the SF6 gas purity of the SF6 inflation device after the new inflation is ≥ 99.8%; The moisture content of SF6 inflators with arc decomposition products is ≤150 μL / L (the micro water content of SF6 inflators without arc decomposition products is ≤250 μL / L). At present, there are two kinds of SF6 gas charging devices for electrical equipment used in the power production process, the manual charging device with...
