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.

XL ---- refers to the [power distribution box], in which X represents [box], L represents [power]; The following digital code represents the design and development number. Power distribution box not too much please

Require, different manufacturers, there will be different "standard" configuration, users can choose different brands of components. According to the design drawings in the system diagram can be customized processing.

Information that can be referred to: Building electrical equipment manuals, factories often use electrical equipment manuals, electrical installation engineering atlas.

Now many manufacturers already have their own models, this model is too much. The main domestic models are MLS, GCS, and GCK GGD. The front three are drawers.

GGD is a fixed cabinet. Foreign manufacturers ABB: MD190, MNS, ArTu Schneider models are: Blokset, 8PT and other models

Other foreign manufacturers are different models, the standard is in accordance with GB7251.1
