1. Observe whether the instrument works normally at any time, pay attention to whether the various electrical connectors are hot to avoid leakage.
2. Check the performance and fixation of all electrical components and their accessories;
3. Regularly check the explosion-proof power distribution box device to see if there is a fault;
4. The movement of the operating mechanism should be kept flexible, and the separation and closing of auxiliary contacts should be correct.
5. Whether the conductive function of each line is good;
6. The column grounding device should be intact.
7. Check whether porcelain insulators, bushings, bus bars and various electrical connector parts are intact;
8. Fixed contacts and fixed contacts should be connected by the same wire, and ensure sufficient pressure.
9. The surface of the cabinet is subjected to electrostatic spraying, and the spraying material must be anti-corrosion and wear-resistant plastic powder;
10. The external fasteners of the explosion-proof distribution box are made of hexagonal stainless steel screws, flat washers and spring washers are also necessary, so that the cabinet can be made tight without any gaps.
11. The rated value of the main switch is compatible with the rated value of the auxiliary switch. 一机一门一保护 ” 实现。 Three-level power distribution is realized by " one machine, one door and one protection " .
