Explosion-proof distribution cabinet of explosion-proof structure composition

 Explosion-proof power distribution cabinet has a good explosion-proof ability, which is widely used in the explosive environment with high risk, especially in the mine.Explosion-proof distribution cabinet structure can be divided into two parts, one is the external structure, the second is the internal structure.

1. External structure

External use was made of 304 stainless steel explosion-proof power distribution cabinet, and each welding mouth tight. In order to prevent the cupboard door open into explosive gas, installed automatically cut off power supply protection device, when open cupboard door just at that moment, it will cut off power supply. The installation outside the cabinet put oneself in another's position the fire or flame arrester, the spark inside the positive pressure tank sputtering to the outside of the tank. Cabinet put oneself in another's surface through special processing, high-speed after blasting powder electrostatic pensu. Cabinet put oneself in another's position, outlet and sealing metal pipe connection, absolutely explosion-proof.

2. Internal structure

The explosion-proof distribution cabinet is filled with air or inert gas, so that the internal pressure of the cabinet is higher than the external pressure, so that explosive gas or dust cannot enter the cabinet. The internal components are also equipped with explosion-proof components, such as explosion-proof buttons, explosion-proof signal lights, explosion-proof switches and explosion-proof instruments.

The explosion-proof power distribution cabinet has two structures, inside and outside, so as to achieve the overall explosion-proof capability. Only in order to effectively achieve the explosion-proof capability, can guarantee the life safety of workers working in this kind of environment.
