Embodiment Construction

[0031] The present invention will be described in detail below in combination with specific embodiments.

[0032] The present invention relates to a catenary system contact suspension monitoring device, comprising a collector 11 for monitoring catenary vibration data and a concentrator 10 for monitoring catenary cable 3 state data. The collector 11 is installed on the contact wire suspension string clamp 13 through screws, and the collector 10 is installed on the catenary cable 3 through the clamp 6 . The collector 11 and the concentrator 10 perform data transmission by connecting cables or wireless communication.

[0033] The collector 11 includes the collector housing 2 and the vibration sensor 8 inside the collector housing 2, which are used to monitor the vibration data of the contact line, and through the analysis and calculation of the acceleration data, confirm the vibration frequency, vibration amplitude and maximum displacement of the contact wire when vibrating and ...

Abstract

The invention relates to a contact suspension monitoring device for an overhead line system, and the device comprises a collector for monitoring the vibration data of a contact line and a gathering device for monitoring the state data of a carrier cable. The collector is installed on a contact line suspended wire clamp through a screw, and the gathering device is installed on the carrier cable through a clamping hoop. The collector and the gathering device carry out the data transmission through a connection cable or in a wireless communication mode. The device is simple in structure, is easy to use, is remarkable in technical effects, can be widely used for occasions of online monitoring product design of contact suspensions (carrier cables and contact lines), meets the working requirements of the outdoor environment of the overhead line system, achieves the real-time monitoring of the swinging, vibration, current and temperature of the contact suspensions (carrier cables and contact lines) and can provide reliable, accurate and complete monitoring data.

Description

technical field [0001] The invention relates to the technical field of catenary monitoring for electrified railways, in particular to a contact suspension monitoring device for a catenary system. 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-spe...
