Explosion-proof electrical equipment for reasons of explosion and prevention - News - Global IC Trade Starts Here.

SMD aluminum electrolytic capacitor

1. If the electrical equipment is maintained and repaired, the protective layer will fall off, so that the explosion-proof surface will fall on the dust and other debris. When the matching joint surface is tightened, pits will appear, which may increase the clearance of the flameproof joint. Therefore, when repairing electrical equipment, maintenance personnel must pay attention to the explosion-proof joint surface to prevent coal dust and debris from sticking to it.

2. The outer casing of the explosion-proof electrical equipment with local roof collapse and damage caused by improper movement and relocation can cause the explosion-proof electrical equipment to detonate. For this reason, electrical equipment should be installed in a well-supported location, and care should be taken when moving and relocating equipment.

3. Due to the unfamiliarity of the performance of the equipment, no special tools or misoperations were used during the loading and unloading process. If the end cap of the explosion-proof motor is removed, it may be damaged by the instrument in order to save trouble, or the end cap may be damaged or an inconspicuous crack may occur, and the explosion may occur. When disassembling, the parts are not marked with steel stamps. When they are assembled, there is no check mark and they are mistaken for interchangeability. The gap is too small. If the gap is too small, the movable joint surface may cause friction and damage the flameproof surface. Therefore, each zero Parts must be stamped and matched during assembly.

4. The explosion-proof surface of the screw is not fastened due to the shallow depth of the screw hole or the screw is too long. To this end, the screw hole should be inspected for impurities and the screw is intact. It should be inspected and disposed of before assembly.

5, due to the staff's lack of mastery of the theory of explosion-proof theory, the failure to properly implement the various procedures, as well as the blast-proof requirements of the equipment, may cause explosions. To this end, we should strengthen the study of theoretical knowledge and procedures, and overcome the idea of ​​numbness.
