The inside of the explosion-proof electrical box enclosure will enter the surrounding explosive gas mixture due to respiration. When the equipment generates sparks and dangerous high temperatures, it will ignite the explosive gas mixture in the shell, forming endless blasting force and shock waves. On the one hand, the flameproof enclosure should be able to accept the internal burst pressure without damage; on the other hand, the joint surface of the explosion-proof enclosure should be able to prevent the blasting flame from transmitting the surrounding blasting gas mixture out of the enclosure. Therefore, the explosion-proof enclosure should have two functions: anti-explosion and explosion-proof. So how to purchase the explosion-proof distribution box correctly? Here's a specific introduction to this issue:

1. In the selection and purchase of explosion-proof electric boxes, the manufacturer of explosion-proof boxes must be selected to meet the strict requirements for the use of electrical components. Some manufacturers who use defective electrical components must be removed. Manufacturers also have to strictly follow the production requirements for production, and continue to improve the inductive nature of production personnel, so that they can do a careful job, reduce the chance of presenting defective goods. Manufacturers should inspect the explosion-proof boxes coming out of the output and do a good job of safety inspection.

2, explosion-proof electrical box device: First of all to understand the color of all the surface of the wire, the switch to understand the logo, all kinds of wire must be careful and regular emissions, but also to be bundled. If it is some very simple parts that show movement, they can be fixed with spikes. If the explosion-proof box is selected by the method of clear installation, then the height from the ground may reach 1.2 meters. If the box is a meter box, then the distance is about 1.8 meters. It must not be possible to open holes in the explosion-proof box with electrical welding.

3, the protection of explosion-proof electrical box : There must be a complete equipment protection *, do a good job of the normal protection of the explosion-proof box, but also to conduct business guidance for these protection personnel, and then to very good protection. In addition, it is necessary to increase investment in the protection of explosion-proof boxes and establish a complete monitoring and protection system.

Carefully read the above information about the installation and placement of the explosion-proof electrical box can have a clear layout in the actual use of the process.
