Product Detail

Features

This explosion proof distribution cabinet is suitable for three-phase four-wire (220V/380V) AC power distribution system and all automatic detection systems in explosive environments such as chemical industry, offshore drilling platform, metallurgy, medicine, light industry, textile, food, bioengineering, aerospace engineering, and military industry.
1.The working principle of the positive pressure cabinet is: the use of explosion-proof measures to isolate the ignition source by the medium to achieve the purpose of electrical explosion-proof.
2.This explosion proof distribution cabinet can be equipped with various common detection instruments, analytical instruments, display instruments, monitors, microcomputer touch screens, high-power frequency converters and ordinary electrical components according to user requirements, and there is basically no restriction on the electrical components installed by users.
3.Explosion proof distribution cabinet is mainly composed of cabinet automatic control system, gas circuit system alarm system and power distribution system. The cabinet body is composed of positive pressure chamber and auxiliary chamber. The auxiliary chamber is equipped with automatic control system, alarm system, air source filtering system and user's incoming and outgoing cables. , The user's power distribution system components are installed in the positive pressure chamber.
4.Explosion proof distribution cabinet can be customized into box type, piano table type and cabinet structure according to user requirements. The cabinet type is divided into upper and lower structures and left and right structures. The box type is generally welded by steel plates, the surface is sprayed with plastic, and the front door is operated. Open the door for maintenance. The steel plate material is generally GB710-88 cold-rolled steel plate, and GB3280-84G stainless steel material can also be selected according to user requirements.
5.There are two types of air connection methods: ventilation type and compensation type. The ventilation type is uninterrupted and continuous air supply. The working heat of the components in the positive pressure chamber can be taken away with the air path, which has a good heat dissipation function. The compensation type is intermittent air supply. , the positive pressure chamber has a good sealing, low air consumption.
6. The user must provide an air source, which is required to be purified air or nitrogen, and the pressure of the air source is: 0.2~0.8MPa; usually the instrument air at the user's site can meet the requirements, and according to the user's requirements, our company can design a self-supplied air for it. system.
