Analysis of Distribution Cabinet Model

Distribution cabinet is the motor control center collectively, the distribution cabinet used in the load is more dispersed, less circuit occasions. In general we see the distribution cabinet are installed in the more subtle corner.

Power distribution cabinet model
There are many power distribution cabinet models, generally different manufacturers have their own models.
Domestic models are MLS, GCS, GCK GGD, etc .;
Foreign manufacturers ABB: MD190, MNS, ArTu, Blokset, 8PT and so on.
The general standard model is GB7251.1

Power distribution cabinet model
First: P-open low-voltage switchgear, G-closed low-voltage switchgear
Second: G-fixed dead, C-withdrawable, H-fixed, out of mixed.
Third place: L (or D) - power, K-control, S-source electrical system
GGD is cheaper, GCS, GCK is economical.
Example: GGD / M / J ①②③
G-AC low-voltage distribution cabinet
G-electrical components fixed installation, fixed wiring
D-power cabinet
M-panel operation
J-static capacitor
① - design number: 1. breaking capacity of 15kA; 2. breaking capacity of 30kA; 3. breaking capacity of 50kA
② - the main circuit program code
③ - auxiliary circuit program code

Power distribution cabinet drawings
1, we usually see more than a few households when the electricity, mostly from a distribution cabinet inside the issue, the simple wiring diagram is like this.

2, the circuit board is divided into a schematic diagram and the second schematic diagram: a schematic diagram is the main circuit schematic diagram, the second schematic diagram is the schematic diagram of the control circuit.
