Electric control cabinet
The high-speed railway control cabinet is a crucial component of the high-speed railway system.
Classification:
The high-speed railway control cabinet is a crucial component of the high-speed railway system, responsible for controlling, protecting, and monitoring the electrical system. The following is a brief introduction to the high-speed railway control cabinet:
Structural composition
The high-speed railway control cabinet usually consists of three main parts: control cabinet, power cabinet, and distribution cabinet. The control cabinet integrates controllers and key components, responsible for controlling the operational status of the electrical system; The power cabinet provides various power sources such as high voltage, low voltage, and direct current to ensure the power supply of the electrical system; The distribution cabinet is responsible for outputting power to the onboard equipment and motor drive system, achieving the normal operation of various functions of the train.
major function
1. Power control: The high-speed railway control cabinet can ensure the correct output of power in the vehicle system, and through precise control and monitoring mechanisms, ensure the safety and stability of power.
2. System protection: It has multiple protection measures such as power short circuit, overvoltage, undervoltage, overcurrent, etc., effectively preventing damage to the electrical system due to faults and ensuring the safety of train operation.
3. Operation status monitoring: It can detect the operation status of the electrical system in real time and provide relevant information, which facilitates the timely detection and handling of potential problems by operation and management personnel.
