Sulfur hexafluoride booster ventilation device of transformer substation

Abstract

The invention belongs to the field of an auxiliary electrical device of a transformer substation, relates to a ventilation device for forcedly discharging the sulfur hexafluoride gas leaked from a high-voltage switch device of the transformer substation, and in particular relates to a sulfur hexafluoride booster ventilation device of the transformer substation, and the sulfur hexafluoride booster ventilation device comprises a transformer substation environmental intelligent security box which is arranged inside the transformer substation, wherein a sulfur hexafluoride sensor which is connected with the transformer substation intelligent environmental security box is arranged inside the transformer substation, one side wall of the transformer substation is provided with an air inlet and a toxicity discharging fan, the other side wall of the transformer substation is provided with the transformer substation intelligent environmental security box, and the side wall of a transformer substation door is provided with a display screen. The sulfur hexafluoride booster ventilation device is installed inside the transformer substation, so that the sulfur hexafluoride concentration inside the transformer substation can be monitored and adjusted; and meanwhile, the display screen which is installed on the outer wall of the transformer substation can be used for displaying and operating the indoor sulfur hexafluoride concentration value in real time.

Description

technical field [0001] The invention belongs to the field of substation auxiliary electrical equipment, and relates to a ventilation device for forcibly exhausting sulfur hexafluoride gas leaked from high-voltage switchgear in a substation, in particular to a substation sulfur hexafluoride pressurized ventilation device. Background technique [0002] As an inert gas, sulfur hexafluoride is widely used in the power industry. At present, sulfur hexafluoride gas is mainly used in high and medium voltage power equipment to play the role of insulation or arc extinguishing. Sulfur hexafluoride gas itself is non-toxic, but it is heavier than air, so when leakage occurs, it will accumulate at the bottom of the indoor air. At this time, if people enter the substation room, they will suffer from hypoxia and even suffocation; Under the action of power arc, spark discharge and corona discharge, sulfur hexafluoride gas can decompose and release various products, mainly SF4 and SF2, and a...

Problems solved by technology

Sulfur hexafluoride gas itself is non-toxic, but it is heavier than air, so when leakage occurs, it will accumulate at the bottom of the indoor air. At this time, if people enter the substation room, they will suffer from hypoxia and even suffocation; Under the action of power arc, spark discharge and corona discharge, sulfur hexafluoride gas can decompose and release various products, mainly SF4 and SF2, and a small amount of fluorine compounds such as S2, F2, S, F, etc., fluorine compounds will cause Damage to insulating materials, fluorine compounds or highly toxic gases
