The difference between central cabinet and ring network cabinet (whether the high-voltage cabinet adopts central cabinet or ring network cabinet)

1, the difference between central cabinet and ring network cabinet.

2. The difference between central cabinet and ring network cabinet.

3. Video of the difference between central cabinet, fixed cabinet and ring network cabinet.

4. The difference between central distribution cabinet and ring network cabinet.

1. Central cabinet, the so-called metal armored movable central closed switchgear.

2. It belongs to high-voltage distribution equipment, with the highest working voltage of 12kV. It is a complete set of indoor power distribution equipment with three-phase AC 50Hz single bus subsection system or double bus subsection system.

3. It is used to receive and distribute 6 to 12kV network power supply, and control, protect, monitor and measure the power supply circuit.

4. The central switch cabinet is mainly used for power transmission of power plants and small and medium-sized generators, power reception and transmission of secondary substations in the power system, power distribution of industrial and mining enterprises and institutions, and starting of large high-voltage motors.

5. The ring network cabinet is a set of electrical equipment with power transmission and distribution equipment (high-voltage switchgear) installed in a metal or nonmetal insulated cabinet or made into an assembled interval ring network power supply unit. Its core part adopts load switch and fuse, which has the advantages of simple structure, small volume, low price, improved power supply parameters and performance, and safe power supply.

6. Widely used in urban residential quarters, high-rise buildings, large public buildings, factories and enterprises and other load center distribution stations and box-type substations.
