On-site explosion-proof junction box introduction and installation operation

First of all, we must first clearly know what the explosion-proof junction box is, the explosion-proof junction box is also called explosion-proof terminal box, explosion-proof junction box, explosion-proof foundation box, explosion-proof protection box, his role is to distribute power, electrical equipment and external Where the line is connected, this place needs a device to protect the line. In this place, a box is added for protection. The inside of the box usually has a terminal block or a terminal without a terminal but a switching device. Aluminum alloy, steel plate welding, stainless steel, engineering plastics, etc.

Field explosion-proof junction box introduction and installation operation mode

Zhejiang Chuangfeng Explosion Electric specializes in the production of explosion-proof box products. Below we introduce the selection and detailed explanation of the explosion-proof junction box.

Explosion-proof junction box selection:

Whether the junction box is flameproof or increased or not, is not the signal inside, but only where the junction box is. If the junction box is located in Zone 1 or Zone 2, it is ok to choose explosion-proof or increase-safety; if it is in the normal zone, you can choose a normal junction box.

Explosion-proof junction box type:

The explosion-proof junction box is a special equipment used in various high-risk places. Compared with the civilian junction box, it is an explosion-proof junction box that has been modified by various explosion-proof functions. It is made of aluminum alloy die-casting or stainless steel welding. The explosion-proof and anti-corrosion junction box is classified 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 structure of use, it is divided into: wall-mounted explosion-proof junction box and vertical explosion-proof junction box.

Applicable environment and location:

1. Zone 1 and Zone 2 hazardous gas sites;

2. Group IIA, IIB, IIC T1-T5 explosive gas or vapor environment;

3. Combustible dust environment 20, 21, 22

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

detailed introduction:

1. Before installing and using the product, check whether the technical data on the nameplate matches the usage.

2. The front stage power supply must be cut off before installation and maintenance;

3. The inlet and outlet cables pass through the rubber sealing ring and must be pressed with washers and compression nuts to ensure that the seals and cables are not loose;

4. The seal ring is corroded, brittle, deformed, sticky or the hardness changes during use.

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

5. During maintenance and disassembly, please note that the explosion-proof surface must not be bumped, scratched or corroded, and regularly coated with 204-1 anti-rust oil;

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

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