Design of Power Distribution Line System for Whole Factory
Nowadays, the importance of electricity in the daily life of people is increasing. In the production process of the factory, in order to ensure the efficient and optimized operation of the production, it is very important to establish a reasonable power distribution line system. In this paper, the relevant design issues of the whole factory power distribution line system are discussed.
1 Design Type
The design of the power distribution line system for the whole factory mainly includes the selection of line type and configuration. According to the customers specific conditions, the design type should be determined. Generally, various sections are set up in order to facilitate the increased power demand due to the customers production process and the increase of machines. In addition, in order to meet the requirements of ground lightning protection and electromagnetic interference, some insulated wires need to be designed as correct.
2 Material Selection
The selection of materials for the power distribution line system mainly depends on the customers site conditions and the requirements of the operation. In general, the main materials used are aluminum, copper and steel. Copper is often selected due to its convenient installation and low resistivity. Moreover, good electrical conductivity ensures the stability of power supply and the normal operation of the machinery. Aluminum is also a quite commonly used material for its light and oxidation resistance.
3 Cable Selection
The selection of cable is also very important for the power distribution line system. Generally, the selection should be based on the voltage and current of the system, as well as the safety standards. In addition to the cable, insulation materials should also be selected. For example, XLPE, FEP and other heat-resistant materials can be used.
4 Protection, Testing and Monitoring
In addition to the design of the power distribution line system, it is also necessary to ensure the safe operation of the power in the production process. Therefore, a comprehensive protection, testing and monitoring system should be configured. In the system, protective devices such as circuit breakers, fuses, disconnectors and earthing switches should be provided to protect the safety of the electric power. In addition, various test instruments can also be used to detect and monitor the safety and stability of the electrical equipment.
5 Control System
Finally, in order to ensure the efficient and optimized operation of the power distribution line system, a centralized control system should be established. Generally, modern systems use programmable logic controllers or distributed control systems. These systems can integrate the data from the whole production process, monitor the parameters in real time, intelligently control the operation, and reduce operating costs and labor costs.
Overall, the design of the power distribution line system for the whole factory has many contents. Various materials and cables must be selected according to the specific conditions of the plant in order to obtain a safe, efficient and optimized electrical system. In addition, some protective and control devices should be set up to ensure the safe operation of the system.
