Which is a good IIC explosion-proof distribution box

定制Instructions：

To customize an explosion-proof distribution box, the first step is to provide the explosion-proof mark of the box. For example: Ex de II B T6

2. Can you directly provide the model, external drawing, and electrical schematic of the explosion-proof distribution box; If none are available, the category of explosion-proof distribution box (lighting or power) needs to be provided

Product features (number of circuits), inlet and outlet ports (quantity, size, and direction), leakage protection, installation environment and method, internal electrical brands (Tengyang conventional electrical brands are ABB, Schneider), etc.

Under normal circumstances, the main switch of the explosion-proof lighting distribution box is 3P, and the sub switch is 2P; the main switch and sub switch of the explosion-proof power distribution box are both 3P; if there are different requirements for switch technology, they need to be described separately. （Which is a good IIC explosion-proof distribution box）

4. If the specifications, directions, and switch currents of the inlet and outlet of the switch are different, corresponding circuit numbers must be described separately

5. If the explosion-proof distribution box switch is waiting for leakage, the leakage current must be described separately for the corresponding number of circuits.

6. Customization can be made according to special requirements. The commonly used materials for Wochuan explosion-proof are copper free aluminum alloy, carbon steel, and stainless steel. Technical data for BEP56 explosion-proof distribution box!

Dangerous area: Combustible gases and combustible dust may appear simultaneously or separately

The shell is welded with steel plates and sprayed with plastic on the surface. Both the main chamber and the wiring chamber adopt explosion-proof structures,

Optional components such as high breaking circuit breakers, AC contactors, thermal relays, control buttons, and signal lights can be installed inside. The opening and closing can be achieved by operating the handle on the shell cover, with reliable performance and indicator lights. Both steel pipes and cables can be used for incoming and outgoing lines, and the direction and internal components of the incoming and outgoing lines can be determined.

Specially designed explosion-proof components for our company, with reliable explosion-proof and electrical functions. （Which is a good IIC explosion-proof distribution box）

routine maintenance

1. The wires in the stationary and fixed contacts should be *, the contacts should be in close contact, and sufficient pressure should be ensured.

2. The grounding device of the column is in good condition

3. Check the performance and fixing condition of all electrical components and accessories.

4. Check the corrosion resistance of metal busbars and wiring terminals, as well as the deformation of busbars under pressure.

5. Inspect and clean all power distribution equipment.

6. The action of the operating mechanism should be flexible, and the auxiliary contacts should be opened and closed correctly.

7. Clean the inside and outside of the power distribution equipment.

8. Pay close attention to the display of instruments and whether various electrical connectors are overheated during work.

9. Check if all connections are in good condition.

10. Check porcelain bottles, sleeves, busbars, and various electrical connectors.

11. After installation or maintenance, attention should be paid to keeping the sealing ring tightly pressed at the inlet of the device to avoid affecting the explosion-proof performance of the product or causing water ingress inside the product and resulting in malfunction.

12. Regularly inspect the sealing ring of the introduction device, and replace it immediately if aging is found on the sealing ring.

13. Regularly inspect the explosion-proof surface and promptly apply anti rust oil to the explosion-proof surface.
