Series explosion-proof lighting (power) distribution box (hereinafter referred to as the distribution box) is suitable for areas and areas containing hazardous places with explosive gas environments of classes or groups below the level and group. It is used in lines with AC, rated voltage or , used to control the starting and stopping of three-phase asynchronous motors, and can also be used to control motors remotely, with overload and short-circuit protection functions.
, aluminum alloy distribution box
, the components used need to be installed In the explosion-proof cavity, the explosion-proof cavity is used to block electrical leakage and contact with dangerous media at the use site to achieve safe production. During production, attention should be paid to first placing the guide rails in the explosion-proof cavity in the correct direction, and the circuit breaker should be firmly stuck on the guide rails On the top, add the mechanism to align the hole position at the cover. The small details of installing the explosion-proof shaft are: There is a small black snap ring on the shaft, which needs to be clamped to fix and tighten it. Once the position is firmly aligned, the handle can be operated It will be flexible, and the opening and breaking positions are clear. Once the handle is stuck, the handle position needs to be readjusted.
The explosion-proof cavity cover is divided into high cover and low cover. Generally, the low cover is commonly used. If a high cover is used, If it is covered, a high cover must be used for AC and above. If a circuit breaker is installed next to it, a corresponding shaft must be used. / The circuit breaker must use a high cover. In addition, the user has provided components, which should be equipped with corresponding ones according to the actual situation. High and low covers.
Pouring and sealing of the flameproof cavity. The wires connected in the flameproof cavity need to pass through the transition nut. The sealing gasket at the transition nut is very critical. The sealing gasket is based on the diameter of the wire and the Open holes according to the number. Pay special attention to the fact that the diameter of the wire must match the hole diameter, and there should be no gaps. Then press the sealing gasket into the transition nut. It must be pressed flat. When pouring, pay special attention to whether there is glue leakage in the sealing gasket. Check the pouring edge to avoid damaging the components. The pouring and sealing must be even and there should be no bubbles.
There are too many precautions and details involved in the assembly process of explosion-proof distribution boxes, which require all of us to pay attention and understand them. Every link.

, structure and characteristics
This distribution box is universal according to the first part of electrical equipment for explosive gas environments. Requirements", Electrical Equipment for Explosive Gas Environments Part 2 Explosion-Proof Type", Electrical Equipment for Explosive Gas Environments Part 3 Increased Safety Type" standards are designed and manufactured, passed the inspection by the national designated inspection agency, and an explosion-proof certificate was issued.
, the shell is made of cast aluminum alloy die-casting, and the surface is sprayed with plastic. The main cavity adopts a flameproof structure, and the wiring cavity has an increased safety structure. Circuit breakers, AC contactors, thermal relays, explosion-proof control buttons, explosion-proof Signal lights, etc. The distribution box adopts a modular design, various circuits can be freely combined, and the selection of electrical components can be determined by the user. It has a compact structure and beautiful appearance. The incoming and outgoing lines can be routed through steel pipes or cables, and the direction of the incoming and outgoing lines can be determined by user requirements.
The shell of the non-standard distribution box is made of steel plate welded and sprayed with plastic on the surface. It is divided into main cavity and wiring cavity, both of which adopt flameproof structure. High-breaking circuit breakers, AC contactors, thermal relays, control buttons, signal lights and other components can be installed inside. The opening and closing can be realized by operating the handle on the shell cover, and the action performance is Reliable and equipped with opening and closing signal lights. The incoming and outgoing lines can be routed through steel pipes or cables. The direction of the incoming and outgoing lines and internal components can be determined by user requirements. Other materials and shapes can be customized according to user requirements.
