Introduction and installation operation method of on-site explosion-proof junction box

First of all, we must first clearly know what the explosion-proof junction box is. The explosion-proof junction box is also called an explosion-proof terminal box, an explosion-proof branch box, an explosion-proof base box, and an explosion-proof protection box. His role is to distribute power, use electrical equipment and external Where the line is connected, this place needs a device to protect the line, and a box will be added as a protection in this place. The inside of the box will generally have a line terminal block or a terminal without a terminal but with a switching device. The general material is Aluminum alloy, steel plate welding, stainless steel, engineering plastics, etc.

Jinshen explosion-proof electrical specializes in the production of explosion-proof box products. Let us introduce the selection and detailed explanation of explosion-proof junction boxes.

Selection of explosion-proof junction box:

Whether the junction box is flameproof or increased safety or non-explosion-proof, it is not what kind of signal is inside, but only where the junction box is located. If the junction box is located in zone 1 or zone 2, it is possible to choose explosion-proof or increased safety; if it is located in a normal area, it is enough to choose a common junction box.

Type of explosion-proof junction box:

Explosion-proof junction box is a special equipment used in various high-risk places. Compared with civil junction box, it is a junction box with explosion-proof function after various explosion-proof transformations. It is made of aluminum alloy die-casting or welded with stainless steel. Explosion-proof and anti-corrosion junction boxes are classified according to: according to the functional material form: explosion-proof explosion-proof junction box, aluminum alloy explosion-proof junction box, stainless steel explosion-proof junction box, steel plate explosion-proof junction box; According to the use structure, it is divided into: wall-mounted explosion-proof junction box and vertical explosion-proof junction box.

Applicable environment and place:

1. Zone 1 and Zone 2 hazardous gas locations;

2. Explosive gas or vapor environment of T1-T5 group â…¡A, â…¡B and â…¡C;

3. Combustible dust environment 20 zone, 21 zone, 22 zone

4. Indoor and outdoor (IP54, IP65 need to be mentioned when ordering).

detailed introduction:

1. Before installing and using the product, check whether the technical data on the nameplate is consistent with the usage;

2. Before installation and maintenance, the power supply of the previous stage must be cut off;

3. The incoming and outgoing cables pass through the rubber sealing ring, which must be compressed with a gasket and a compression nut to ensure that the seal and the cable cannot be loose;

4. During the use of the sealing ring, corrosion, brittleness, deformation, tackiness or hardness change exceed the factory

20% should be purchased and replaced from the manufacturer in time to ensure reliable explosion-proof performance;

5. During maintenance and disassembly, pay attention to that the explosion-proof surface must not bump, scratch or corrode, and regularly apply 204-1 anti-rust oil;

6. The distribution box should be checked regularly during use to ensure its good operation;

7. Non-professionals are strictly prohibited to open the cover for maintenance and inspection.
