What Is The Internal Structure Of The Distribution Box And Distribution Cabinet?

"Distribution box", also called power distribution cabinet, is a general term for motor control center. The distribution box is a low-voltage power distribution device that assembles switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on the screen according to the electrical wiring requirements.

The distribution box is a mass of parameters on the data, which generally constitutes a low-voltage forest. According to the electrical wiring, switchgear, measuring instruments, protective appliances and auxiliary equipment are required to be assembled in a closed or semi-enclosed metal cabinet or on the screen to form a low-voltage power distribution. box. During normal operation, the circuit can be switched on or off by means of manual or automatic switches.

The purpose of distribution box:

Reasonable distribution of electric energy to facilitate the opening and closing operations of the circuit. It has a high safety protection level and can visually display the conduction state of the circuit.

The principle of distribution box: The distribution box is a low-voltage distribution box that assembles switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on the screen according to the electrical wiring requirements. During normal operation, the circuit can be switched on or off by means of manual or automatic switches. In the event of failure or abnormal operation, the circuit can be cut off or alarmed by means of protective appliances. By means of measuring instruments, various parameters in operation can be displayed, and some electrical parameters can also be adjusted to prompt or send signals for deviations from the normal working state.

Power distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), which are the final equipment of the power distribution system. Power distribution cabinet is a general term for motor control center. The power distribution cabinet is used in situations where the load is relatively scattered and there are few circuits; the motor control center is used in the situations where the load is concentrated and there are many circuits. They distribute the electrical energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This class of equipment shall provide protection, monitoring and control of the load.

Power cabinet refers to the combination of electrical control cabinets that provide power for the normal operation of the entire machine, including contactors, frequency converters, high-voltage cabinets, transformers, etc.
