The Distribution Cabinet Is A Decentralized Small Capacity Distribution Equipment
- Aug 24, 2017 -

Distribution cabinet is the motor control center collectively, the distribution cabinet used in the load is more dispersed, less circuit occasions. In general we see the distribution cabinet are installed in the more subtle corner.

The power distribution cabinet can change the state and parameters of the circuit automatically or manually according to the requirements of the operation signal or the external field signal, Distribution Cabinet and realize the control, protection, measurement, indication and adjustment of the circuit or the controlled object. The role of distribution cabinet are:

(1) control functions such as the elevator up and down movement, fast and slow automatic switching and automatic stop layer.

(2) protection according to the characteristics of equipment, equipment, environment, Distribution Cabinet and personal protection, such as motor overheating protection, power short circuit protection, leakage protection.

(3) Measurement of the use of equipment and the corresponding electrical appliances, equipment, power grids or other non-electrical parameters, such as current, voltage, power, speed, temperature, humidity and so on.

(4) regulating the role of power distribution cabinet can be some of the electricity and non-power to adjust to meet the requirements of users, Distribution Cabinet such as diesel engine throttle adjustment, room temperature and humidity regulation, automatic adjustment of illumination and so on.

(5) to indicate the role of the use of power distribution cabinet control, protection and other functions, to detect the operation of the equipment and electrical circuit work, Distribution Cabinet such as insulation monitoring, protection from the card instructions.

(6) conversion role in the conversion between the electrical equipment or the distribution cabinet, the control circuit put into operation in time to achieve the function switch, such as the excitation device manual and automatic conversion, power supply and self-power switch The

Power distribution cabinet sub-power distribution cabinet (box) and lighting distribution cabinet (box), measuring cabinet (box), is the final power distribution system equipment. Distribution cabinet is the motor control center collectively. Distribution cabinet used in the load is more dispersed, less circuit occasions; Distribution Cabinet motor control center for the load concentration, the circuit more occasions. They allocate the power of a circuit of a power distribution equipment to a nearby load. This level of equipment should provide protection, Distribution Cabinet monitoring and control of the load.

Grading

(1) a power distribution equipment, collectively referred to as power distribution center. They are concentrated in the enterprise substation, the power distribution to different locations of the lower power distribution equipment. This level of equipment only step-down transformer, Distribution Cabinet so the higher electrical parameters, the output circuit capacity is also larger.

(2) secondary power distribution equipment, power distribution cabinets and motor control center collectively. Power distribution cabinet used in the load is more dispersed, fewer circuits; motor control center for the load concentration, the circuit more occasions. Distribution Cabinet They allocate the power of a circuit of a power distribution equipment to a nearby load. This level of equipment should provide protection, monitoring and control of the load.

(3) the final power distribution equipment is called lighting power distribution box. They are far from the power supply center and are scattered small capacity distribution equipment.
