Additional wire monitoring device for overhead contact mesh

Abstract

The invention relates to an additional wire monitoring device for overhead contact mesh. The additional wire monitoring device comprises a cylinder-shaped shell body, and an electronic device for real-time monitoring and data transmission is arranged inside the shell body; through holes which are passing holes for additional wire are formed in the shell body in the axial direction, and clamps are arranged on both ends of the through holes; an antenna for monitoring data wireless transmission is arranged outside the shell. The product is simple in structure and easy to use, the technical effect is remarkable, the additional wire monitoring device can be widely used in the occasion of online monitoring product design of additional wire for the overhead contact mesh, the field environment work request of the overhead contact mesh system is satisfied, the real-time monitoring of the swinging, vibration, electrical current, and temperature of the additional wire for the overhead contact mesh is achieved, and reliable, accurate and comprehensive monitoring data can be provided.

Description

technical field [0001] The invention relates to the technical field of electrified railway catenary monitoring, in particular to a monitoring device for additional conductors of the catenary. Background technique [0002] The electrified railway catenary is arranged in the open air along the railway line, and the line is long and there is no backup. With the rapid development of electrified railways, especially the expansion of the scale of high-speed electrified railway network, the railway department has put forward higher requirements for the operation safety of traction power supply system. Catenary system is an important part of high-speed railway power supply system. Its infrastructure Maintenance is faced with an urgent need to ensure safety, improve efficiency, and reduce costs. [0003] The catenary system is eroded by wind, frost, rain, snow and other natural environments all the year round, as well as the impact and vibration of the pantograph during high-speed o...

AI Technical Summary

Problems solved by technology

[0004] In the field environment, the additional conductors of the catenary will spontaneously ignite and swing due to the influence of wind. When the swing frequency of the additional conductors reaches a specific condition, galloping or vibration will easily occur on the site, which will accelerate the fatigue loss of the additional conductors and cause serious damage to the catenary infrastructure. security risks

[0005] At present, catenary monitoring mainly adopts manual patrol method, which has problems such as low efficiency, poor accuracy, and slow response speed. It not only consumes a lot of labor costs, but also is limited by time and weather conditions. Hidden dangers in safe and stable operation
