Overview of Electrical Equipment
Xinchi Electric focuses on the research and production of electrical equipment, including DC circuit breakers, DC surge protectors, photovoltaic fuses, dual power supplies kb0、 Multiple fields including fire monitoring, multifunctional instruments, intelligent lighting modules, etc. In addition, we also offer a wide range of products including molded case circuit breakers, miniature circuit breakers, surge protectors, high-voltage circuit breakers, and high-voltage isolating switches.
The distribution box is an important component of the electrical system, which collects a large amount of data and parameters. In the field of low-voltage distribution, it carefully combines switchgear, measuring instruments, protective appliances, and auxiliary equipment in enclosed or semi enclosed metal cabinets according to the requirements of electrical wiring, thus forming a low-voltage distribution box. This system can not only connect or disconnect circuits manually or automatically during normal operation, but also quickly cut off circuits or issue alarm signals through protective appliances in case of faults or abnormal operation. In addition, the distribution box is equipped with measuring instruments to display the real-time conductivity status and various operating parameters of the circuit, while providing necessary adjustment and control functions.
Functions of distribution boxes and cabinets
Low voltage distribution box
Distribution cabinets (boxes) are key equipment in power distribution systems, divided into types such as power distribution cabinets (boxes), lighting distribution cabinets (boxes), metering cabinets (boxes), etc. They are responsible for distributing the electrical energy of the higher-level distribution equipment to nearby loads in a reasonable manner, while providing necessary protection, monitoring, and control functions.
Power distribution cabinet
The power cabinet is an electrical control cabinet combination that provides power for the normal operation of the entire machine, which may include key equipment such as contactors, frequency converters, high-voltage cabinets, transformers, etc. Its role is crucial to ensure that the machine can operate stably and efficiently. Power cabinet, as a type of distribution cabinet, is designed to provide power and control for power equipment such as electric motors. Both 10kV high voltage cabinets and 400V low voltage cabinets, regardless of their functions (incoming, outgoing, metering, capacitance, interconnection, etc.), can be collectively referred to as distribution cabinets.
The relationship between distribution cabinet and control cabinet
Below 400V low-voltage cabinet, if the load is power facilities (such as fans, motors, pumps, etc.), it is called a power cabinet; If the load is equipment such as lamps, switches, sockets, etc., it is called a distribution box. As a small power distribution box, the distribution box contains power switches and safety devices inside. The control box is similar, but it also adds relays or contactors for controlling designated equipment, such as electric motors. Distribution cabinets and control cabinets are large-scale versions of distribution boxes and control boxes, providing power or control outputs with greater power or more channels. The control screen is a special form where all internal devices are installed on the panel and only provide a front control interface.
