Rail Traffic
The application of low-voltage components in the field of rail transit mainly includes intelligent low-voltage distribution system, lighting control system, etc. These systems ensure the safe, reliable and efficient operation of rail transit through intelligent control technology.
Intelligent Low-voltage Distribution System
Intelligent low-voltage power distribution system is an important part of rail transit. Through information technology, system network and other technical means, remote control and monitoring of low-voltage components are realized. Its main functions include real-time data acquisition, remote control, fault analysis, historical event recording and equipment maintenance management, etc., to ensure the stability and safety of electric power transportation.
Lighting Control System
Lighting control system is also widely used in rail transit. Because most rail transit facilities are built underground, the station lacks natural lighting, so the lighting system needs to provide continuous lighting during operation. Intelligent lighting control technology can adjust the lighting brightness according to the actual demand, and realize energy saving and intelligent management.
Typical Low-voltage Components And Their Functions
Circuit breaker: used for on-off control of the circuit to protect the circuit from overload and short circuit.
Contactor: used to control the start, stop and reverse of motors and other electrical equipment.
Relay: used to automatically control the on-off of the circuit, often used for signal control and protection.
Switch: used to connect or cut off the circuit and control the opening and closing of the equipment.
Fuse: When the circuit is overloaded, it can quickly cut off the circuit and protect the equipment and lines.
Leakage protector: detect leakage current to prevent electrical fire and personal electric shock accidents.
These components ensure the normal operation and safety of the rail transit system through the functions of control, regulation and protection.
