The difference between switchgear and distribution cabinet

Release time:2018-11-29 11:09:00 Source:http://wap.gxsenge.net Classification:Company dynamics Views

Many things we hear about high and low voltage switchgear and distribution cabinets in our daily lives are related to controlling electricity. So what is the difference between the two? Below, the editor will briefly discuss the differences between switchgear and distribution cabinets.


Simply put, the box for distributing electrical energy is called a distribution box. Mainly used for controlling and distributing electrical equipment, providing protection against overload, short circuit, and leakage in power lines. Distribution boxes are installed in various places, such as schools, government agencies, hospitals, factories, workshops, homes, etc., such as lighting distribution boxes, power distribution boxes, etc.

A switchgear is a complete set of switchgear and control equipment. It serves as a power center and main distribution device. Mainly used for controlling, monitoring, measuring, and protecting power lines and major electrical equipment. Often installed in substations, distribution rooms, etc.


The equipment inside the switchgear mainly serves the functions of opening and closing, and is called differently due to different functions. It has the same appearance and functions as the main power control. Generally, a switchgear with only one large circuit breaker is called a switchgear, while a distribution cabinet is mainly used for energy distribution. A cabinet that divides energy into different functions and is implemented by different circuits is called a distribution cabinet.


In addition to differences in function, installation environment, internal structure, and controlled objects, the notable characteristics of distribution boxes and switchgear are their different external dimensions. Distribution boxes have a small volume and can be hidden inside walls or stand on the ground; The switchgear has a large volume and can only be installed in substations and distribution rooms.


A distribution cabinet is a low-voltage distribution device that assembles switchgear, measuring instruments, protective appliances, and auxiliary equipment into a closed or semi closed metal cabinet or screen according to electrical wiring requirements. During normal operation, the circuit can be connected or disconnected using manual or automatic switches. There are many classifications of distribution cabinets. When it malfunctions or operates abnormally, use protective appliances to cut off the circuit or give an alarm. By using measuring instruments, various parameters during operation can be displayed, and certain electrical parameters can also be adjusted to prompt or signal deviations from normal working conditions. Commonly used in various power generation, distribution, and substations.


The size of the distribution cabinet is relatively large, enclosed on all four sides, and is generally used for low voltage; The size of the distribution panel is smaller than that of the distribution cabinet, with equipment installed on the front and open on the back. It is generally used for low voltage and DC; The distribution box is relatively simple, enclosed on all sides, with a single general purpose, control and protection, and easy maintenance; A distribution board is usually a flat board with components installed on it, fixed to walls, brackets, or equipment, and is generally used for low voltage.
