Power Distribution Cabinet

Power Distribution Cabinet
1. Definition: refers to the final level equipment of power distribution cabinet, lighting distribution cabinet, metering cabinet and other distribution systems.
2. Classification: (1) class I power distribution equipment is collectively referred to as power distribution center. They are centrally installed in the enterprise’s substation and distribute electric energy to lower level distribution equipment in different locations. This level of equipment is close to the step-down transformer, so it has high requirements for electrical parameters and large output circuit capacity.
(2) Power distribution cabinet and power distribution center are collectively referred to as power distribution equipment. The power distribution cabinet is used in occasions with scattered load and few circuits; Motor control center is used for occasions with concentrated load and many circuits. They distribute the electric energy of a certain circuit of the upper level distribution equipment to the nearby load. This level of equipment shall provide protection, monitoring and control for the load.
(3) The final power distribution equipment is generally called lighting power distribution box. They are far away from the power supply center and are scattered small capacity power distribution equipment.
3. The installation requirements are: the distribution board (box) shall be made of non combustible materials; Open distribution boards can be installed in production places and offices with low risk of electric shock; Closed cabinets shall be installed in processing workshops, casting, forging, heat treatment, boiler room, carpentry room and other places with high risk of electric shock or poor working environment; In hazardous workplaces with conductive dust or flammable and explosive gases, closed or explosion-proof electrical facilities must be installed; All electrical components, instruments, switches and circuits of the distribution board (box) shall be arranged in order, firmly installed and easy to operate. The bottom surface of the floor mounted plate (box) shall be 5 ~ 10 mm higher than the ground; The height of the center of the operating handle is generally 1.2 ~ 1.5m; There are no obstacles within the range of 0.8 ~ 1.2m in front of the plate (box); The protection line is reliably connected; No bare electrified body shall be exposed outside the board (box); The electrical components that must be installed on the outer surface of the board (box) or on the distribution board must have reliable screen protection.
4. Features: the product also adopts a large screen LCD touch screen to comprehensively monitor the power quality such as voltage, current, frequency, useful power, useless power, electric energy, harmonic and so on. Users have a clear view of the operation status of the power distribution system in the machine room, so as to find potential safety hazards and avoid risks as soon as possible. In addition, users can also choose ATS, EPO, lightning protection, isolation transformer, UPS maintenance switch, mains power output shunt and other functions to ensure the safety and stability of the power distribution system in the machine room.
