Automatic start of abnormal indoor status: If the sub-zone control function is not defined, the system will automatically start the fan if the SF6 concentration or oxygen level alarm of any indoor detection unit is generated. The duration of continuous ventilation is the set time for continued ventilation until SF6 and oxygen are restored to normal.

At present, the application of SF6 leak monitoring and alarm system in the market is divided into qualitative detection and quantitative detection. Qualitative generally adopts thermal cracking and laser technology, qualitative testing products have high stability and high detection accuracy, which can meet most customer needs; The quantitative detection products use the principle of infrared spectroscopy, that is, the principle of infrared laser, its detection accuracy is high, up to 1ppm, but

With the rapid development of China's electric power industry and the improvement of technical equipment level, SF6 electrical equipment has been put into operation in large quantities. SF6 gas relative molecular mass is large, its density is more than 5 times that of air, once the leakage, SF6 gas will be deposited in the lower part of the air, resulting in a large amount of accumulation of SF6 gas in the lower part of the equipment, resulting in the occurrence of anoxic asphyxia accident.

SF6 gas is widely used in power equipment as an insulating medium and arc extinguishing gas, especially in high-voltage circuit breakers, transformers, transformers, capacitors, arresters, fuses and so on. Leakage occurs, the equipment pressure is reduced, and the insulation capacity is reduced; Pollute and destroy the atmosphere, increase the greenhouse effect; Accumulation in the lower space, resulting in brain hypoxia, and even rapid suffocation accidents; Under the influence of partial disch
