Explosion-proof distribution box is a special type of electrical equipment, which is mainly used in flammable and explosive places such as petroleum, chemical industry, and mining. In order to ensure the safety of these places, the installation of explosion-proof distribution boxes needs to be carried out in strict accordance with the specifications. This article will give you a detailed introduction to the installation method and method of explosion-proof distribution box.
1. Choose the right installation location.
The explosion-proof distribution box should be installed in a dry, well-ventilated place free of corrosive gases and dust, avoiding the influence of direct sunlight and heat sources. At the same time, sufficient maintenance and ventilation space should be maintained around the distribution box.
Second, the installation of the foundation.
In order to stabilize the explosion-proof distribution box, a foundation needs to be installed first. The material of the foundation can be metal or concrete, and its dimensions should be suitable for the weight of the distribution box and the installation location. The foundation should be level, and ensure that the distribution box can be firmly placed on the foundation.
3. Connect the power supply.
According to the needs of the equipment, the switches and fuses in the distribution box are reasonably arranged. Ensure that the voltage and current of each equipment meet the requirements. Then, use a cable to connect the distribution box with the power supply, making sure that the cable connection is secure and not loose.
4. Install explosion-proof seals and gaskets.
Install explosion-proof seals and gaskets near the terminal blocks to ensure the sealing performance between the electrical equipment and the distribution box. First, place the explosion-proof gasket inside the terminal hole and place the explosion-proof gasket on the seal. Finally, use a screwdriver to secure the gasket and sealing ring to the terminal block.
5. Tighten the explosion-proof screws.
After connecting the cable, use a screwdriver and screws to tighten the explosion-proof screws to ensure that the terminal block is securely connected to the cable. At the same time, be careful not to use excessive force to avoid damage to the explosion-proof distribution box.
6. Check the wiring.
After wiring, use a wire gauge to check that each connection point is secure and reliable. If there is any abnormal situation, please deal with it in time.
With the above steps, you have successfully completed the installation of the explosion-proof distribution box. Please note that in daily use, regularly check the wiring of the explosion-proof distribution box to ensure the safe operation of electrical equipment.
