Comprehensive monitoring and protecting device for traction power supply of urban rail transit

Abstract

The invention discloses an urban rail transit traction power supply comprehensive monitoring protection device, and relates to the technical field of monitoring protection. The comprehensive monitoring and protecting device for the traction power supply of the urban rail transit comprises a main body device, the main body device comprises a shell, a monitoring device is arranged in the shell and comprises a base, the lower surface of the base is fixedly connected with the middle of the lower inner wall of the shell, and vertical plates are fixedly connected to the left side and the right side of the upper surface of the base; the upper ends of the two vertical plates jointly penetrate through and are rotationally connected with a main column through a bearing, the outer side of the main column is fixedly sleeved with a rotating cylinder, a cylinder groove is formed in the surface of the rotating cylinder, the cylinder groove is annular and obliquely formed, a groove column is slidably inserted into the cylinder groove and matched with the cylinder groove, and the middles of the faces, close to each other, of the two vertical plates are jointly connected with a lower plate. The comprehensive monitoring and protecting device for the traction power supply of the urban rail transit can detect and protect the traction power supply system of the urban rail transit in real time.

Description

technical field [0001] The invention relates to the technical field of monitoring and protection, in particular to a comprehensive monitoring and protection device for urban rail transit traction power supply. Background technique [0002] Urban rail transit is a vehicle transportation system that adopts rail structure for load-bearing and guidance. According to the requirements of the overall planning of urban transportation, fully enclosed or partially enclosed dedicated rail lines are set up to transport a considerable amount of passenger traffic in the form of trains or bicycles. ; Urban rail transit includes: subway system, light rail system, monorail system, tram, maglev system, automatic guided rail system, and urban express rail system. [0003] At present, the urban rail transit projects all use the traction power supply system, and the traction current required by the train is provided by the traction substation. The traction substation transmits the direct curren...

Problems solved by technology

Stray currents not only cause potential rise, but also cause anode corrosion to equipment. Stray current corrosion can cause damage to concrete structures, corrode rails and their accessories, buried pipelines, burn drainage equipment, interfere with communication, etc., and in severe cases affect The use of equipment is more likely to threaten personal safety, so there is an urgent need for comprehensive monitoring and protection devices for urban rail transit traction power supply to solve the above-mentioned problems
