Briefly Understand The Power Distribution Cabinet

The power distribution cabinet is the general name of the motor control center. The power distribution cabinet is used in occasions where the load is scattered and the circuits are few. Generally, we see that power distribution cabinets are installed in relatively hidden corners.

Friends who are interested in the power distribution cabinet can simply understand the type of the power distribution cabinet and the relevant information of the power distribution cabinet drawing.

Distribution cabinet model:

There are many types of power distribution cabinets, generally different manufacturers have their own models. Domestic models are MLS, GCS, GCK GGD, etc.; foreign manufacturers ABB are: MD190, MNS, ArTu, Blokset, 8PT, etc.

The general standard model is GB7251.

1 Model cabinet meaning:

First place: P-open low-voltage switchgear, G-closed low-voltage switchgear

Second place: G-fixed dead, C-drawable, H-fixed, drawable mixed type.

Third place: L (or D)-power, K-control, S-Senyuan electrical system GGD is cheaper, GCS, GCK are economical. Example: GGD/M/J①②③ G- AC low-voltage distribution cabinet G- fixed installation of electrical components, fixed wiring D- power cabinet M- panel operation J- electrostatic capacitor ①- Design number: 1. Breaking capacity is 15kA; 2. The breaking capacity is 30kA; 3. The breaking capacity is 50kA ②-main circuit program code ③-auxiliary circuit program code.

2 Magnetic drawing of power distribution cabinet:

1. When we usually see electricity from multiple households, most of them are sent from a distribution cabinet. The simple wiring diagram is like this.

2. The circuit diagram of the distribution board is divided into a primary schematic diagram and a secondary schematic diagram. The primary schematic diagram is the main circuit schematic diagram, and the secondary schematic diagram is the control circuit schematic diagram.

3. The above are the schematic diagram, expansion diagram, terminal block diagram, installation wiring diagram, etc. of the intelligent power distribution cabinet. These wiring are troublesome, and the intelligent power distribution cabinet is more convenient to operate.

The primary components of the power distribution cabinet are: air switch, knife open, contactor, thermal relay, etc.; the secondary components on the panel are: voltmeter, ammeter, transfer switch, indicator light, button, etc.; the secondary components installed in the cabinet are : Intermediate relay, time relay, etc.; auxiliary accessories are: wire, terminal, fuse, etc. In addition, there are many power distribution cabinets equipped with: PLC, inverter.
