304 stainless steel explosion-proof box 300*400*200 flameproof type IIB 316 stainless steel explosion-proof junction box

This type of box can be customized according to customer requirements. The switch button of the inlet and outlet can also be customized according to the drawing

Suitable for:

1. Explosive gas environment zone 1 and zone 2;
2.IIA, IIB and IIC explosive gas environment;
3. Environments with temperature groups T1~T4;
4. Explosive and dangerous environment such as oil mining, storage, chemical industry, medicine, military industry and military facilities;
5. Power conversion, distribution and control in power distribution system;

Product features:
1. There are two types of main and deputy cabinets: left and right, upper and lower. The main cabinet is a positive pressure sealing chamber, front and rear doors are opened, and observation Windows are set on the front.
2. It has the operation functions of automatic air change before opening, air change delay, automatic air supply and automatic control of positive pressure range.
3. The operation is simple and convenient, and the "positive pressure operation" state will be entered upon the end of ventilation.
4. With positive pressure protection (upper and lower limits), sound and light alarm, positive pressure critical lower limit automatic power off, open the door power off, emergency manual power off and other safety interlocking protection functions.
5. Cable voltage coil introduction device.
6. All kinds of instruments, frequency converter, soft starter, PLC programmable controller and computer control system can be installed inside the product, which can realize local and remote control.

Principle of explosion protection:
Explosion-proof distribution cabinet adopts the explosion-proof measure of dielectric isolated ignition source to achieve the purpose of electrical explosion-proof, which is the explosion-proof principle of positive pressure ventilated explosion-proof cabinet. That is, all the electrical components of the user are installed in a shell full of clean media with positive pressure, so that the flammable and explosive mixed gas substances in the external environment cannot touch the electric spark or dangerous temperature generated by the electrical components in normal work, so as to achieve the purpose of electrical explosion protection.
