Structure and characteristics
This distribution box is in accordance with
Electrical equipment for explosive gas environments
Part 1 General Requirements",
"Electrical Equipment for Explosive Gas Atmospheres
Part 2 Explosionproof Types
",
"Electrical Equipment for Explosive Gas Atmospheres
Third Part of the increased safety type
》standard design and manufacture, passed the inspection by the national designated inspection agency, and issued an explosion-proof certificate.
The shell is made of cast aluminum alloy die-casting, and the surface is sprayed with plastic. The main cavity is explosion-proof type structure, the wiring cavity has an increased safety structure. It can be equipped with circuit breakers, AC contactors, thermal relays, explosion-proof control buttons, explosion-proof signal lights, etc. The distribution box adopts a modular design, with various The circuits can be freely combined, and the selection of electrical components can be determined by the user. It has a compact structure and beautiful appearance. The incoming and outgoing wires can be routed by steel pipes or cables, and the direction of the incoming and outgoing wires can be determined by the user's requirements.
Non-standard power distribution The box shell is made of steel plates welded and sprayed with plastic on the surface. It is divided into a main cavity and a wiring cavity, both of which adopt explosion-proof structures. High-breaking circuit breakers, AC contactors, thermal relays, control buttons, signal lights and other components can be installed inside. The handle on the shell cover realizes opening and closing, with reliable action performance, and is equipped with an opening and closing indicator light. The incoming and outgoing lines can be routed by steel pipes or cables, and the direction of the incoming and outgoing lines and internal components can be determined by user requirements.

and use
Use
Before installing and using the product, check whether the technical data on the nameplate is consistent with the usage
Installation The front-end power supply must be cut off before maintenance and repair
The incoming and outgoing cables pass through the rubber sealing ring and must be compressed with washers and compression nuts to ensure that the sealing and cables do not loosen
If the sealing ring is corroded, brittle, deformed, sticky or has a hardness change exceeding that of the factory during use
it should be purchased and replaced from the manufacturer in time to ensure reliable explosion-proof performance
During maintenance and disassembly, pay attention to the explosion-proof surface not to be bumped, scratched or corroded, and apply anti-rust oil regularly
The distribution box should be inspected regularly during use to ensure its good operation
br/>
Non-professionals are strictly prohibited from opening the cover for maintenance and inspection.
