Description

Explosion-proof block terminal with function of putting out a fire

Technical Field

The invention relates to the technical field of electrical equipment, in particular to an explosion-proof distribution box with a fire extinguishing function.

Background

The explosion-proof distribution box is characterized in that parts which can generate sparks, electric arcs and dangerous temperatures are all placed in an explosion-proof shell, and the internal space of equipment is separated from the surrounding environment by the explosion-proof shell. The explosion-proof shell has a gap, and due to the respiration and gas permeation of the electrical equipment, an explosive gas mixture can exist in the explosion-proof shell, when the explosion-proof shell explodes, the shell can bear the generated explosion pressure without damage, and meanwhile, the shell structure gap can cool flame, reduce the flame propagation speed or stop an accelerating chain, so that flame or dangerous flame products cannot penetrate through the explosion-proof gap to ignite an external explosive environment, and the explosion-proof purpose is achieved.

Even as an explosion-proof distribution box, explosion and fire cannot be completely avoided, so that the distribution box has a fire extinguishing function, and the Chinese patent application with publication number of CN114759447A discloses an intelligent fire extinguishing distribution box. Including block terminal, stationary blade, divide electric module, power transmission pipe, transmission pipe etc. the upper and lower both sides middle part of block terminal rear side all is equipped with the stationary blade, is equipped with the power transmission pipe in the middle of the inside rear side of block terminal, and power transmission pipe top is equipped with divides electric module, divides electric module top interval to be equipped with three transmission pipe, and the power transmission pipe upper portion all wears out the block terminal top. When the top plate of the technical scheme moves upwards, the electric switch can be driven to move downwards, so that the electricity distribution module is powered off, the increase of fire is avoided, meanwhile, the balancing weight can be driven to drop downwards, the fire extinguisher can start working, and accordingly fire extinguishing work is completed.
