Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and more specifically to a wireless control system for rail transit. Background Technology

[0002] Rail transit refers to a type of transportation vehicle or system that requires vehicles to run on specific tracks. Urban rail transit line DC short-circuit testing is an experiment simulating a DC short-circuit fault in a DC power supply system. By creating abnormal electrical conditions, it observes the system's response, verifies the stability of related equipment, and obtains important equipment parameters to evaluate the performance of the equipment and protection system. Short-circuit testing can verify the performance of electrical equipment under extreme conditions, ensuring that the equipment can withstand short-circuit impacts in actual operation; it can also verify the sensitivity and stability of the protection system, ensuring that the protection system can function promptly and accurately when a short-circuit fault occurs, thereby preventing equipment damage. Short-circuit tests can detect potential problems in power systems, providing a basis for fault analysis and prevention. They can also provide data support for the design, improvement, and optimization of power systems, helping to enhance system reliability and stability. Furthermore, short-circuit test results help improve the skills of operation and maintenance personnel, enabling them to better understand the operating characteristics of equipment under short-circuit conditions and ensuring the safe operation and maintenance of the power system. To ensure the stable operation of the power supply system after the subway line opens, a 1500V DC short-circuit test is required on the 1500V contact network before trial operation to verify and evaluate the performance of the equipment and protection system. Therefore, a DC short-circuit test instrument has been specially developed.
