Explosion-proof control cabinet explosion-proof level requirements
Posted on

Explosion-proof level requirements of explosion control cabinets, there are material requirements, and which components are there are no provisions which manufacturer, the domestic main or Chint, Delixi, Changshu, foreign is the most Schneider; general like If there is an electronic circuit diagram for the explosion-proof control cabinet, this is the basis for the supplier's engineer's quotation. Engineers will give you a reasonable size, compact and reasonable structure, versatility, and flexibility. The basic focus is on these
This depends on the size, material, explosion-proof signs, and degree of protection of the BXK explosion-proof electrical control box. Explosion-proof electrical equipment belongs to safety-related special equipment, and procurement must be prudent; there are many fake goods on the Internet, and some people are unaware of fearlessness, irresponsibility, and dare to do it.
How to choose the suitable explosion-proof box explosion-proof distribution box
First of all, to meet the electrical performance;
On the other hand, to meet the explosion-proof requirements, the selected explosion-proof signs must meet the explosion-proof requirements for hazardous gases at the place of use. Explosion-proof distribution boxes can be used in hazardous locations where flammable or explosive gases or flammable dust are present, through explosion-proof certification of qualified third party inspection agencies.
Aluminum alloy explosion-proof distribution box how much money
Explosion-proof box is divided into: gas explosion-proof explosion-proof type, increased safety type, dust explosion-proof type; explosion-proof type in the IIB, IIC; and the size is different, the introduction of different quantities of the device prices vary greatly.
Can explosion-proof electrical control cabinets have touch screens
Can install the display screen, but the touch screen is difficult, after all, the touch screen is not explosion-proof, and the touch screen is still exposed.
If it only plays a role in display, the control cabinet can be made into two layers, and an explosion-proof transparent glass can be added on the outside, so that the touch screen has no way to touch, and it becomes a display screen.
What is the role of AC contactors in explosion-proof distribution boxes?
The electrical components in the explosion-proof distribution box are the same as the normal distribution box. The contactor controls the load. The difference between the explosion-proof distribution box and the ordinary distribution box is the difference in the structure of the box.
What is the difference between explosion-proof and anti-corrosion power distribution box and water discharge dust-proof and anti-corrosion distribution box?
Explosion-proof anti-corrosion distribution box material is generally engineering plastics, protection class is generally IP54, waterproof, dustproof and anti-corrosion distribution box material is generally engineering plastics, the protection level is higher, will not be lower than IP56.
Non-standard customized explosion-proof distribution box
1, first provide explosion-proof distribution box rating, such as EX de IIBT6. The explosion-proof signs show the explosion-proof distribution box explosion-proof type and applicable environment.
2, suggest that customers provide drawings, pictures, parameter model data as much as possible. Such as electrical schematics, outline drawings.
3, if you can not provide detailed drawings and data, we need to understand the type of explosion-proof cabinet you want to customize: such as lighting, power, wiring.
Determine the enclosure material of the explosion-proof box (cast aluminum, carbon steel, stainless steel, other), protection class (IP65/IP55/other),
Anti-corrosion grade (WF1/WF2), installation form (wall, vertical, mobile, other).
4, explosion-proof box control requirements: the need for several loops, the loop current and voltage, whether with leakage.
5, explosion-proof box component brand: Our common component brands are: Chint, Schneider, ABB, there are specific component brands please communicate with our technical people.
6, under normal circumstances, the explosion-proof distribution box master switch is 3P, sub switch is 2P; Explosion-proof power distribution box master switch and sub switch are 3P; if the switch technology has different requirements, need to be described separately.
7, Explosion-proof distribution box switch with leakage, corresponding to the number of loops to describe the leakage current.
8, can be customized according to special requirements: install the instrument, heat, etc.
