Host controlling system for SF6 leakage warning system and controlling method thereof

Abstract

The invention discloses a host controlling system for an SF6 leakage warning system. The host controlling system for the SF6 leakage warning system comprises a main controlling module, a displaying module, a warning module and a power source module, wherein the main controlling module is respectively connected with an external sampling analyzing unit and a fan controlling unit through a bus, the displaying module is connected with the main controlling module through a circuit, the warning module is connected with the main controlling module through a circuit, and the power source module supplies electric energy to the host controlling system. The invention further provides a controlling method of the host controlling system for the SF6 leakage warning system. According to the host controlling system for the SF6 leakage warning system and the controlling method of the host controlling system, by means of the GSM mobile network, the conditions of a leakage warning site are reported to maintenance personnel through a short message, and therefore the defects that an SF6 switch gear room is short of an effective communication mode and remote monitoring is difficult to conduct are overcome. Therefore, the host controlling system for the SF6 leakage warning system and the controlling method of the host controlling system achieve remote monitoring of the system, break through geographic restrictions and environmental restrictions, achieve concentration and monitoring, and guarantee safe production of electric power.

Description

Technical field [0001] The invention relates to a gas leakage alarm system, in particular to a gas leakage alarm system used for SF 6 The host control system of the leakage alarm system and its control method. Background technique [0002] Sulfur hexafluoride (SF 6 ) The gas has good electrical insulation performance and excellent arc extinguishing performance, and is widely used in electrical switchgear; at the same time, it is a kind of asphyxiant, exposed to oxygen content <19.5% of the atmosphere can cause dizziness, vomiting, loss of consciousness or death; SF 6 The decomposition product sulfur tetrafluoride (SF 4 ), sulfur difluoride (SF 2 ) Is highly toxic and harmful to human eyes and respiratory system. Sulfur hexafluoride (SF 6 1) Gas leakage has a great impact on personal safety and environmental protection. To this end, the national "Electrical Industry Safety Work Regulations" and "SF 6 The Regulations on the Management of Operation, Maintenance and Overhaul of Sw...
