Distribution box

The distribution box is the total circuit distribution box for all users.

working principle

The distribution box is according to the electrical wiring requirements of the switch equipment, measuring instruments, protective appliances and auxiliary equipment assembled in a closed or semi-enclosed metal cabinet or screen, constitute a low-voltage power distribution device. Normal operation can be manual or automatic switching Through or cut off the circuit. Fault or abnormal operation with the protection of electrical cut off the circuit or alarm by measuring the instrument can display the various parameters in operation, but also for some electrical parameters to adjust the deviation from the normal working state of the prompt or issued The signal is often used in the hair, with, substation.

Structural use

Distribution boxes and distribution cabinets, power distribution boards, power distribution screen, is a centralized installation switches, meters and other equipment, complete sets of devices.

category

Common distribution boxes are made of wood and metal two, because the metal distribution box protection level to be higher, so the metal is used more.

use

The use of distribution box: a reasonable distribution of energy to facilitate the opening and closing of the circuit operation. Have a higher level of security, can be intuitive display circuit on-state. Easy to manage, when the circuit fault is conducive to maintenance.
