Circuit emergency cut-off switch

Abstract

The invention discloses a circuit emergency cut-off switch, and relates to the field of fire emergency. The circuit emergency cut-off switch comprises a male head and a female head which connect two cables together, the male head and the female head are located in a connector box, the side surfaces of the male head and the female head are provided with a male head connecting piece and a female head connecting piece which are matched with each other, and the male head connecting piece and the female head connecting piece are provided with corresponding jacks. A plug pin is inserted in the jack, on and off of the electromagnetic coil is controlled through a water path capable of automatically spraying water, and through a series of linkage mechanisms, after the electromagnetic coil is closed, a cable can be snapped from a connector through an energy storage spring immediately so that a circuit can be automatically and rapidly cut off when a fire occurs. And meanwhile, when a cable joint is disconnected, an arc extinguishing gas can be automatically sprayed to the joint so that new potential safety hazards caused by electric arcs generated when a circuit is emergently cut off are prevented.

Description

technical field [0001] The invention relates to the field of fire rescue, in particular to a circuit emergency cut-off switch. Background technique [0002] At present, the city has a large population and dense buildings. All kinds of buildings need to pay attention to the issue of safety and fire protection. At present, most urban buildings are equipped with automatic fire extinguishing systems. When a fire is detected, they will automatically spray water to extinguish the fire, and then kill most of the fires in the cradle. [0003] At the same time, electric energy is used as the main energy source in urban buildings, and various electrical equipment and electrical circuits are distributed in every corner of the building. Both the circuit and the electrical equipment will generate heat, and even leakage, short circuit and other phenomena may occur. When a fire occurs, the energized electrical equipment and circuits are very easy to ignite, and when spraying fire, the wa...

AI Technical Summary

Problems solved by technology

When a fire occurs, the energized electrical equipment and circuits are extremely easy to ignite, and when spraying water to extinguish the fire, the water can easily cause a short circuit in the energized state

[0004] Therefore, when a fire occurs, it is best to disconnect the circuit, and the circuit disconnection must be manually shut down, or the air switch will automatically trip when there is a leakage or a short circuit. These two disconnection methods are relatively slow.
