The function of the power distribution cabinet is to distribute electrical energy to various load locations through power distribution control, and to maintain a power-off state when the line is short-circuited, overloaded, or leaked. The types of power distribution cabinets include fixed panel power distribution cabinets, protective power distribution cabinets, drawer power distribution cabinets, and power lighting distribution cabinets. Let’s take a look at the structure and use of power distribution cabinets.
1.Fixed panel distribution cabinet
The fixed panel type power distribution cabinet is also called the power electrical panel. The front is the power distribution cabinet panel, which can be used for shielding and opening and closing, and the back and sides are opening and closing, which can contact live equipment.
The protection panel of the fixed panel type has a low protection level and can only be used in some cases where the safety requirements are not high and the power supply is continuous. For example, it can be used in rooms where industrial and mining enterprises collect power transformers.
2. Protect the distribution box
Compared with the fixed-panel power distribution cabinet, the protective power distribution cabinet has a cabinet transposition in the true sense. In addition to the installation surface, there are baffles sealed around it. The cabinet of the protective power distribution cabinet is composed of insulation materials, internal electrical components and external partitions, and these components can also be selected between the partitions. Therefore, the protective power distribution cabinet has a high level of security and can be applied TECHNICAL FIELD A power distribution device.
3.Drawer type distribution cabinet (Withdrawable Switchgear )
Drawer type distribution cabinet is one of the countries with the highest security of power distribution equipment. A large number of manufacturers of power distribution boxes should choose steel cabinets for the type of drawers. The internal equipment of the cabinet has a drawer. To form an independent functional unit. Drawer-type power distribution cabinets are more reliable, interchangeable, and safer than the above two types of power distribution cabinets, and are suitable for centralized control power distribution bases that require high power reliability.
4. Power lighting distribution cabinet
Power lighting distribution cabinets use enclosed devices, and the safety levels are different and different according to the requirements of the application. Power lighting distribution cabinets are mainly used as primary power distribution equipment, such as power distribution control at the production site of industrial and mining enterprises.
