Explosion-proof control cabinet shell welded steel or cast aluminium alloy or 304 stainless steel die-casting, high-pressure electrostatic spraying surface, the product as a whole is generally used in explosion-proof shell and increased safety shell combined into a composite structure.

Explosion-proof shell components can be installed inside the explosion-proof buttons, explosion-proof components, explosion-proof signal lamps, explosion-proof switch and explosion-proof instrumentation and other explosion-proof components and AC contactors, thermal relays, temperature controllers and a variety of functional modules and other common electrical components; increase the safety of the shell inside the installation of buttons, control switches, instruments, etc. are explosion-proof components. The internal components of the control box are arranged according to the user's requirements, and a variety of functions can be achieved. The internal components and the colour of signal lamps should be specified by the user when selecting the type, and the product has many variations according to the user's requirements, and the electrical wiring diagram must be provided when ordering. Explosion-proof control cabinet can be divided into vertical, hanging type.

Explosion-proof control cabinet operation principle: explosion-proof control cabinet is equipped with clean gas or inert gas that does not contain explosive gases, sealed cabinet, the pressure inside the cabinet is slightly higher than the air pressure outside the cabinet, the pressure gauge is mounted in the cabinet, which is usually used for on-line analysis of the pressure gauge. Positive pressure explosion-proof distribution cabinet with computer, PLC, operating station or other pressure gauges. The explosion-proof principle of the positive pressure cabinet is to introduce the protective gas from the safety zone into the positive pressure chamber by means of the control system in the explosion-proof control cabinet together with the pneumatic system, which is thoroughly cleaned. combustible gases in the positive pressure chamber. After replacement, the pressure inside the positive pressure chamber is maintained, preventing the entry of combustible gases and conductive dust from the external hazardous environment, thus achieving the purpose of explosion protection.

Design of a fully cemented enclosure which is rigorously designed, manufactured and equipped with all connections. The explosion protection methodology is based on extremely strict design and manufacturing standards, as well as rigorous operating procedures for installation, wiring and maintenance. Electrical equipment and pressure gauges identified as explosion-proof by this method are usually very large and heavy and must be shut down for operation, but in many cases it is also a very useful method.
