A, explosion-proof distribution box shell cast aluminum alloy die casting molding, appearance spray. The main chamber chooses the flameproof structure, and the wiring chamber increases the safety structure. It can be equipped with circuit breakers, contactors, thermal relays, transformers, fuses, Ex explosion-proof control buttons, signal lamps, transfer switches, etc. The power distribution cabinet adopts modular planning, various circuits can be freely combined, and the selection of electrical components can be determined by the user. The structure is compact and the appearance is beautiful. Inlet and outlet lines can be selected by using steel pipes or cables. The direction of the entrance and exit lines can be determined by the user's requirements.
B, explosion-proof non-standard distribution box: shell steel plate welding, plastic spray appearance. The main chamber and wiring chamber are divided into explosion-proof structures. Components such as high breaking circuit breakers, communication contactors, thermal relays, control buttons, and signal lamps can be selected. After the operation covers are closed, the handles are completed and the operation functions are completed. Solid and equipped with indicator lights. The inlet and outlet wires can be selected by using steel pipes or cables. The direction of the inlet and outlet ports and internal components can be determined by the user's requirements.
The function of the distribution box is that the distribution control distributes the electric energy to each load location, and performs power off maintenance when the circuit is short circuited, overloaded, and leaked. Today, we Luoping Explosion-proof Electric Co., Ltd. introduced us to the distribution control circuit of the distribution box.
(1) The primary distribution equipment is collectively referred to as the middle of power distribution. They will be installed in the company's substations to distribute power to lower-level power distribution equipment at different locations. This level equipment is close to the step-down transformer, so the electrical parameters demand is higher and the output circuit capacity is also larger.
(2) Secondary distribution equipment is the general term for the middle of power distribution cabinets and motor control. The power distribution cabinet is used in applications where the load is relatively loose and there are few loops. In the middle of the motor control, it is used in occasions where the load gathers and the loop is large. They distribute the electrical energy of a certain circuit of the upper distribution equipment to the nearest load. This class of equipment should maintain, supervise and control the load supply.
(3) The final power distribution equipment is collectively referred to as the lighting power distribution box. They are far away from the middle of power supply and are scattered small-capacity power distribution equipment.
