use
This device is suitable for power distribution systems in power plants, petroleum, chemical industry, metallurgy, textiles, high-rise buildings and other industries. In large power plants, petrochemical systems and other places with a high degree of automation that require computer interfaces, it can be used as a three-phase AC frequency of 50 (60 )Hz, a low-voltage complete power distribution device used for power distribution, motor centralized control, and reactive power compensation in power generation and power supply systems with a rated operating voltage of 380V (400V) and (660V) and a rated current of 4000A and below .
Model and meaning
Conditions of use
a. The ambient air temperature is not higher than +40°C and not lower than -5°C. If the average temperature within 24 hours is not higher than +35°C, the equipment must be derated according to actual conditions when operating above the above ambient temperature;
b. For indoor use, the altitude of the use location shall not exceed 2000m
c. Relative humidity of the surrounding air It should not exceed 50% when the maximum temperature is +40°C. A larger relative humidity is allowed at lower temperatures, such as 90% at +20°C. It should be considered that condensation may occasionally occur due to temperature changes. Influence;
d. When the device is installed, the inclination with the vertical plane does not exceed 5%, and the entire cabinet row is relatively flat (in compliance with GBJ232 standards);
e. The device should be installed in a location that is free from severe vibration and impact and is not sufficient to expose electrical components to undue stress. Corrosive places;
f. When users have special requirements, they can negotiate with the manufacturer.

Structural description
The main frame of the device is made of 8MF steel. The frame adopts two structural forms: assembly and partial connection. There are mounting module holes E=20mm on the main frame.
The functional rooms of the device are strictly separated. The compartments are mainly divided into functional unit rooms and busbar rooms. The functions of each unit are relatively independent.
The device does not adopt the traditional design of placing the horizontal main busbar on the top of the cabinet, so that there are outlet channels above and below the cable room. It solves the problem of old products not being able to go offline.
The size series of the device cabinet are as follows:
