The transverse testing mechanism comprises an upper inspection seat and a lower inspection seat, an information feedback system is installed on the testing device, the information feedback system comprises an information acquisition end and an information collection end, the information collection end is connected with an information processing terminal, and the information processing terminal is provided with an early warning information parameter system. The information collection end transmits collected information to the information collection end, the information collection end transmits the collected information into the early warning information system, the information collection end is connected with a vehicle system mileage system, and through processing and information collection of the device and the system, collection of damage or abrasion conditions of an overhead line system is completed. And safe operation of the line is ensured.

Description

technical field [0001] The invention relates to the technical field of track catenary, in particular to a safety warning device and system for testing catenary lines. Background technique [0002] With the rapid economic development, the pace of urbanization is gradually accelerating, and the urban traffic is more and more worthy of consideration. The power supply system is an important part of urban rail transit. The reliable and safe power supply of the power supply system ensures the normal operation of the subway. The subway power supply system consists of two parts: one part is the high-voltage power supply system (external power supply), that is, the urban power grid, which often has three power supply modes: centralized, decentralized and hybrid; The lighting power supply system is composed together to rectify the three-phase high-voltage AC provided by the traction substation into low-voltage DC suitable for the application of subway vehicles. Various types of ligh...

AI Technical Summary

Problems solved by technology

Once the subway catenary fails, it will lead to the interruption of subway operation and cause major economic losses

Therefore, real-time detection of key nodes of catenary is very necessary. Due to long-term use and wear during use, line failures and gaps in lines will occur, but this will cause safety hazards, and this hidden danger will be greatly increased. In order to ensure the safety and stability of the line, it is necessary to design a safety warning device and system that can perform a catenary line test.
