The explosion-proof motor terminal box is a part of the explosion-proof motor casing. Usually, the explosion-proof motor is connected to the wire inside the explosion-proof motor terminal box to prevent the wire and the air from contacting and causing safety accidents.
 
Features of explosion-proof motor terminal box
The cable sealing structure of explosion-proof motor terminal box is an important part to ensure the explosion-proof performance of the terminal box. Its main functions are: first, to meet the sealing requirements; second, to meet the explosion-proof requirements. The sealing structure of explosion-proof motor terminal box cable has various forms such as sealing ring compression sealing, packing sealing, rubber sealing, etc., but for high-voltage explosion-proof motors, it is mostly sealing ring compression sealing structure. Because this structure is more flexible for the arrangement and connection of various rubber multi-core power cables and signal transmission cables, it has strong adaptability.
 
Precautions for the use and maintenance of explosion-proof motor terminal boxes
1. If you need to disassemble and assemble the explosion-proof motor terminal box, special attention should be paid to protecting the explosion-proof surface and windings from bumps. If multiple units are disassembled and assembled at the same time, the disassembled parts should be stored separately, and mixed assembly is not allowed. If the dismantled parts will be put aside for a period of time, the necessary anti-rust treatment should be carried out on the flameproof surface.
2. Non-professionals are strictly prohibited from disassembling and repairing the explosion-proof motor terminal box and any other parts of the explosion-proof motor.
3. Set up short-circuit, overload, overheating, and lack of equal protection in strict accordance with the requirements, and regularly check these protection devices to ensure that they are effective.
 
The explosion-proof motor terminal box contacts the power line of the explosion-proof motor inside the motor to avoid direct contact with the air. It should be noted that the explosion-proof motor terminal box seal must be handled properly, and the temperature of the explosion-proof motor terminal box should be paid attention to in time.
