The safety and reliability of the explosion-proof distribution box is the key to controlling the explosion. Some improper operations in daily life will bring safety hazards to explosion-proof distribution boxes. For example, in the repair process, even some seemingly insignificant factors may be the fuse of the explosion. In order to avoid such uncontrollable accidents. The maintenance procedure itself does not cause the possibility of fire and explosion. For soldering and chips, an effective way to reduce the risk of fire is to carefully check the hidden dangers to safety caused by various changes in the design and structural materials. However, there will be minor changes in maintenance, so the risks that these minor changes bring to the entire device should be correctly evaluated and preventive maintenance should be carried out. During the repair process, parts made of qualified materials must follow their correct installation methods.



During maintenance, ensure that the equipment requirements are as follows:

1. The explosion-proof distribution box has neat wiring and no articulation;

2. The wires are tightly connected and will not damage the core wire or break the strands;

3. The cross-sectional area of the conductor on both sides of the screw under the washer is the same;

4. There are no more than two wires connected to the terminal on the same terminal;

5. Check that the gasket has complete parts and tight wire connections;

6. For some explosion-proof distribution boxes that need to be opened, pay attention to the opening of the hole not to be very rough;

7. The internal wiring layout of the explosion-proof distribution box should not be messy, and the places that need to be fixed must be reinforced;

8. The explosion-proof distribution box should be installed firmly to facilitate future operation and maintenance;

9. During maintenance, ensure that the wires in the distribution box should be well insulated, arranged neatly, and fixed firmly. The ends of the wires should be connected by bolts or crimping.
