1、 Concept of complete distribution cabinet
A complete distribution cabinet is a comprehensive power distribution equipment that integrates energy distribution, short-circuit protection, overload protection, undervoltage protection, leakage protection, grounding protection, and intelligent control and monitoring. It is a common power equipment in small and medium-sized distribution systems.
2、 The functions and characteristics of a complete set of distribution cabinets
1. Electricity distribution: A complete set of distribution cabinets can distribute electricity to different electrical equipment according to different electricity needs.
2. Protection and control: The complete distribution cabinet can provide various protection measures for the power system, such as short circuit, overload, undervoltage, leakage and grounding protection, to ensure the safe operation of the system.
3. High reliability: The structure of the complete distribution cabinet is complex, but it is well-designed and has the characteristics of high reliability and long service life.
4. Easy maintenance: The complete set of distribution cabinets is easy to maintain and replace electrical and protective components, ensuring the reliable operation of the equipment.
5. Intelligence: In recent years, the intelligence level of complete distribution cabinets has been continuously improved, which can monitor energy consumption, achieve precise measurement and remote control.
3、 Application scope
Complete distribution cabinets are widely used in industrial, commercial, and residential fields. In the industrial field, complete distribution cabinets are usually used in the power systems of small and medium-sized factories and enterprises to meet the power needs of different occasions. In the commercial field, complete sets of distribution cabinets are widely used in places such as shopping malls, supermarkets, hotels, and office buildings to ensure the safe and stable operation of the power system. In the residential field, complete sets of distribution cabinets are mainly used in large residential areas such as high-rise buildings and villas to ensure the safety of residents' electricity use.
4、 The role of complete distribution cabinets in power distribution systems
The power distribution system is a complex electrical system consisting of incoming cabinets, switch cabinets, distribution cabinets, transformer and distribution rooms, low-voltage distribution rooms, etc. Among these devices, the complete set of distribution cabinets plays a crucial role. The complete distribution cabinet is the last branch in the system, responsible for delivering electrical energy to various electrical equipment and providing complete protection for the power system. The complete distribution cabinet has multiple functions such as converting power, protecting power, controlling power, measuring power, and monitoring power, enabling the power system to operate smoothly, safely, and efficiently.
【 Summary 】
A complete distribution cabinet is a comprehensive distribution equipment in the power system that integrates functions such as energy distribution, protection, control, and monitoring. It has the characteristics of high reliability, easy maintenance, and intelligence. In the power distribution system, complete distribution cabinets play a crucial role in ensuring the safe, stable, and efficient operation of the power system.
