First, the role of power distribution cabinet
1, to the power supply equipment (power supply to the device);
2, start and stop operation of electrical equipment (with start and stop button);
3, the operation of testing equipment (set signal indicator, a current meter voltmeter);
4, protection of electrical equipment (circuit breaker) Power cabinet is the power distribution cabinet, is designed to power equipment (generally refers to the motor) to provide power and control of the power distribution cabinet.

Second, the power distribution cabinet Scope:
Suitable for industrial and civil buildings for the exchange frequency of 50Hz, rated voltage 380V and below, three-phase four-wire, three-phase five-wire power system power distribution, lighting distribution and motor control.

Third, the power distribution cabinet types:
1, according to the applicable venue power cabinet can be divided into outdoor and indoor two
2, according to the system capacity and switch size, the cabinet width of 600, 700, 800, 1000mm four, the cabinet depth of a 400mm, box height of 1600, 1700, 1800, three.

Fourth, the power distribution cabinet installation conditions
(1) installation height does not exceed 1000 meters above sea level;
(2) ambient temperature is not higher than +40 ℃, not lower than -20 ℃;
(3) the relative humidity of air does not exceed 85%;
(4) there is no conductive dust and sufficient to corrode the metal and damage the insulation of gas places;
(5) where there is no danger of explosion;
(6) there is no violent vibration and bumps and vertical tilt of not more than 5 ° place.
(7) After treatment with wet and tidal requirements, the power tank can be used in areas where the relative humidity of air does not exceed 95%, there is condensation and mold.
