The rated current of the low-voltage distribution cabinet is AC 50Hz, and the rated voltage is 380V. As the power source of the distribution system, this product has strong breaking capacity, good dynamic and thermal stability, sensitive electrical design, convenient combination, series and innovative structure. What is the purpose of a low-voltage distribution cabinet? Below, Wuxi Shengminghua will provide a detailed explanation.
1. It has a wide range of uses, suitable for setting up factories, mines, enterprises, shopping malls, hotels, campuses, airports, ports, hospitals, high-rise buildings, residential areas, and other occasions. It can be used as power, lighting distribution, and motor control equipment, suitable for indoor wall mounted and outdoor floor mounted devices.
2. It is also used in power systems with AC 50HZ and voltage below 500V for controlling fire pumps, submersible pumps, fire fans, fans, lighting distribution cabinets, etc. The control methods include direct start control, star delta voltage reduction start control, and soft start control.
Precautions for using distribution cabinets:
1. Fixed positions and responsibilities. Low voltage distribution boxes should be numbered, registered, archived, managed in a hierarchical manner, with clear responsibilities, and regularly inspected and maintained for technical purposes.
2. Set standards and assessments. According to the maintenance schedule of the distribution cabinet, regular inspections should be carried out.
