Problems solved by technology

[0003] Most of the low-voltage distribution box rooms are usually unattended distribution box rooms, and the environmental conditions of the distribution box rooms are different. The sulfur hexafluoride leak detector used in each distribution box only has the pressure of the air chamber. Detection and alarm function, when the pressure value alarm signal is sent out, it has reached the time limit for gas inspection and repair, otherwise continuous leakage will cause the density circuit breaker to be blocked and affect the safety of equipment operation
Since the gas leakage in the gas chamber cannot be detected in time, the gas chamber with slow leakage and annual leakage rate exceeding the standard cannot be quickly found, which will cause hidden dangers to the stable operation of the equipment

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to a sulfur hexafluoride environmental monitoring system and method based on a rapid response mechanism. Background technique [0002] Sulfur hexafluoride (sulfur hexafluoride) is a colorless, odorless, non-toxic, non-flammable stable gas. Since SF6 gas has excellent arc extinguishing performance, insulation performance and good chemical stability, since the mid-1960s, SF6 is widely used as an insulating medium for high-voltage electrical equipment. SF6 gas-insulated fully enclosed switchgear occupies a much smaller area than conventional open high-voltage power distribution devices, so it is not only widely used in extra-high voltage and extra-high voltage power systems, but also has begun to be used in power distribution networks, especially low-voltage distribution systems. In the electrical box room, the SF6 gas insulated circuit breaker has the adv...
