Product features of positive pressure dust explosion proof distribution cabinet
1. The shell of the product is welded with high-quality steel plate or stainless steel, and the surface is sprayed with electrostatic powder after high-speed polishing, with beautiful appearance;
2. This product is an improved explosion-proof product of "Zhongtong electric", which can be installed with various common detection instruments, analysis instruments, display instruments, transformers, soft starters, frequency converters, PLC, various buttons, switches, micro-computer touch screen and ordinary electrical components according to the user's requirements, so the installation of electrical components by users is not limited;
3. Diversified design, including cabinet type (upper and lower form, left and right form), wall hanging type, piano table type, plane type, etc;
4. The power distribution cabinet is composed of cabinet body, control system, gas distribution system, alarm system and power distribution system;
Some explosion-proof components of control system and power distribution system components of users are installed in positive pressure chamber (split type or online type can be customized according to customer requirements);
5. The air intake mode of the left and right cabinets is ventilation type, i.e. continuous gas supply. The working heat of the components installed in the positive pressure chamber can be taken away with the gas path, which has good heat dissipation effect.
6. Table guard door can be added according to customer's requirements, which can display the display or action of internal control part;
7. Wiring mode: steel pipe or cable, explosion-proof hose can be used;

Explosion proof principle of positive pressure dust explosion proof distribution cabinet
Flame proof medium isolation measures are adopted.That is: the electrical components used by users are installed in a cabinet full of positive pressure clean gas, so that the flammable and explosive mixed gas in the external environment can not contact the electric spark or dangerous temperature produced by the electrical components in normal operation, so as to achieve the purpose of explosion-proof electrical appliances.
