As the core component of the power system, the electrical cabinet carries vital functions.
It is not only responsible for distributing electrical energy, but also the key to ensuring the safe and stable operation of equipment. Of course, there are many types of distribution cabinets, including fixed panel type, protective type, drawer type, and power lighting distribution cabinets. Their main function is to distribute electrical energy and ensure that electricity can be smoothly delivered to various load points. At the same time, the distribution cabinet also has a power-off protection function to deal with abnormal situations such as circuit short circuit, overload or leakage. In short, the distribution cabinet is a cabinet device that integrates a variety of electrical components and is specially used for power distribution and protection.
Distribution cabinets are widely used in living places such as residential buildings, schools, hospitals, and corporate factories and workshops. In these scenarios, distribution cabinets often appear in the form of lighting distribution boxes and power distribution boxes to provide stable power support for life and work. In addition, distribution cabinets are also divided into primary, secondary and low-level tertiary distribution equipment to meet the power needs of different occasions.
The structure and function of the distribution box
As the core component of the power supply system, the distribution box has a relatively complex structure and a large output circuit capacity. It is usually installed in a substation and is responsible for distributing electric energy from the primary distribution equipment to the secondary distribution cabinet. The distribution box contains a variety of components, such as busbars, circuit breakers, relays, integrated relay protection devices, metering instruments, etc., which work together to achieve effective monitoring and control of the power system.
Classification of electrical cabinets
Distribution cabinets can be divided into many types according to their functions and application scenarios. Among them, power distribution cabinets and motor control centers are two common distribution cabinets. Power distribution cabinets are usually used in occasions with fewer circuits and dispersed loads, while motor control centers are suitable for areas with more circuits and concentrated loads. It mainly undertakes the power distribution task of the primary distribution cabinet and reasonably distributes the power to nearby loads. In addition, lighting distribution cabinets and power distribution cabinets are also indispensable components of the distribution system. They have relatively small capacity and are arranged more dispersedly, and are mainly responsible for controlling the lowest level of load distribution.
1. Fixed panel distribution cabinet
Fixed panel distribution cabinet, also known as distribution panel, has a design feature that the front is equipped with a cabinet panel, which has both shielding and opening and closing functions. The back and sides are open structures, so that the live devices are exposed. This design makes the protection level of the fixed panel distribution cabinet relatively low. Therefore, it is mainly suitable for those occasions where safety requirements are not very strict and continuous power supply is required, such as centralized power supply in the transformer room of industrial and mining enterprises.
2. Drawer-type distribution cabinet
Drawer-type distribution cabinet is famous for its excellent safety. Its cabinet body is made of steel plate and is equipped with retractable drawers inside. Various electrical components are installed in these drawers, and each drawer constitutes an independent functional module. This design not only improves the reliability and interchangeability of the distribution cabinet, but also ensures its safety, which is far better than the two distribution cabinets mentioned above. Therefore, the drawer-type distribution cabinet has become an ideal choice for centralized control distribution centers that have high standards for power supply reliability.
