Distribution Cabinets Are Widely Used In The Distribution Control Of Residential Buildings
- Sep 26, 2017 -


The distribution cabinet, also known as the Power Distribution box, is a cabinet that integrates electrical components for power distribution. Power distribution cabinets have two main functions: first, the power equipment for distribution and control, the second is in the circuit overload, Distribution Cabinet short-circuit and leakage, to provide power failure protection.

Because of its good function, the distribution cabinet is widely used in the distribution control of residential buildings, schools and hospitals.

The power distribution cabinet is the general designation of Motor Control Center. The power distribution cabinet is used in the occasions where the load is more dispersed and the circuit is less, Distribution Cabinet and the motor control center is used for load concentration and circuit. They allocate electricity from one circuit of the upper-level distribution device to the nearest load. This level of equipment should provide protection, monitoring and control over load.

Classification:

(1) First-class distribution equipment, collectively referred to as Power Distribution center. They are centrally installed in the enterprise's substation, which distributes electricity to lower power distribution units at different locations. This level of equipment only rely on step-down transformers, Distribution Cabinet so the electrical parameters of higher requirements, output circuit capacity is also larger.

(2) Two-level distribution equipment is a general designation of power distribution cabinets and motor control centers. The power distribution cabinet is used in the occasions where the load is more dispersed and the circuit is less; They allocate electricity from one circuit of the upper-level distribution device to the nearest load. This level of equipment should provide protection, Distribution Cabinet monitoring and control over load.

(3) The final power distribution equipment is always known as the lighting power distribution box. They are far away from the power centers and are decentralized small-capacity distribution devices.

Distribution cabinets are mainly lighting distribution cabinets and power distribution cabinets, Distribution Cabinet their capacity is relatively small, layout is also more decentralized, mainly responsible for the control of the lowest level of load distribution.
