Low-voltage distribution cabinet model meaning interpretation

There are many types of low voltage distribution cabinets such as: GGD, GCS, MNS, JYD, GCK, etc

The standard is generally in accordance with GB7251.

GGD/M/J123 G-switched low-voltage distribution cabinet G-fixed installation of electrical components, fixed wiring D/M/J-D: power cabinet

M: Panel operation J: Electrostatic Capacitor 1 Design No.: 1. Breaking capacity is 15kA; 2. Breaking capacity is 30kA; 3. Breaking capacity is 50kA

2-main circuit program code 3- auxiliary circuit program code

PGL □—□ P-Low-Voltage Open Distribution Cabinet G-Electrical Component Fixed Installation, Fixed Wiring L-Power

Front □ - Designation number Back □ - Main circuit scheme number PGL1 type is 15KA (effective value), PGL2 type is 30KA (valid value);

Now that PGL is basically unused, most of the power is taken by GGD.

GGD AC low-voltage distribution cabinet: G--low-voltage distribution cabinet; G--fixed installation, fixed wiring; D--power cabinet

GCK AC low-voltage distribution cabinet: G - cabinet structure; C - withdrawable; K - control center.

GCS AC low-voltage distribution cabinet: G - closed-type switchgear; C - withdrawable; S - Senyuan electrical system The price is not divided, mainly depends on the choice of internal components.

The model of the low-voltage cabinet may be different due to different manufacturers, and the model is slightly different. General low-voltage cabinet can be divided into fixed, drawer, frame type. As long as you are sure which situation to use,

The short-circuit capacity of the cabinet, the bus current, the specifications of the main line switch, and the specifications of each branch can allow manufacturers to assist in the selection. Although it is best to have a one-line diagram
