The rated current of the low-voltage distribution cabinet is 50Hz alternating current, and the rated voltage is 380v. Power distribution system is used for power conversion and control of power, lighting and distribution. The product has the characteristics of strong breaking ability, good dynamic and thermal stability, flexible electrical scheme, convenient combination, strong series and practicality, novel structure and so on.
Extended data:
The wiring process is as follows:
1. site selection: in order to ensure the normal and safe operation of the low-voltage distribution cabinet, the low-voltage distribution room should be located near the load center, and the place should be free of dust and corrosive media, otherwise it should be cleaned in time. In order to ensure safety, it is best to have a dry environment and try not to have vibration.
2. Layout of power distribution equipment: The layout of power distribution equipment in low-voltage distribution room must be based on the premise of safety, reliability, applicability and economy, and be convenient for installation, operation, handling, maintenance, testing and monitoring. The high and low voltage electrical equipment rooms located in the same room and the power distribution cabinets arranged in rows must have a proper distance and access exits.
When arranging distribution equipment, necessary safety measures should be taken. If there is a potential danger, the exposed charged body should be shielded or placed out of people's reach. When it is difficult to use the protective cover and cover, a barrier can be used for protection.
Three. The layout of distribution lines shall meet the following conditions: conform to the environmental characteristics of the installation site and the characteristics of buildings, consider the moderate distance between people and lines, consider the electromechanical stress that may be caused by short circuit, and consider other stresses that may be suffered by lines during installation and use and the weight of conductors.
4. What factors will affect the use of distribution lines: prevent external heat from affecting the use, prevent water from affecting the use, prevent external mechanical damage from affecting the use, prevent dust from falling on the wiring and prevent strong radiation from affecting the use.
