Example Embodiment

[0028] The present invention will be described in detail below in conjunction with specific embodiments.

[0029] The present invention relates to a catenary tension monitoring device. The device comprises a cylindrical shell, which is provided with a through hole along the axial direction, which is a through hole for a catenary clue (including: a load-bearing cable, an additional wire, etc.). The aperture can be adjusted adaptively according to the diameter of the catenary leads of different specifications. The shell is axially divided into two left and right sections. The left section of the housing includes a left upper housing 1 and a left lower housing 2, which are axially symmetrically butted up and down and fixed by screws; the right section of the housing includes a right upper housing 6 and a right lower housing 7, both axially Butt up and down symmetrically and fixed by screws. After being closed, it has a cylindrical cylindrical structure with good wind resistance. ...

Abstract

The present invention relates to a contact net tension monitoring device. The device comprises a cylindrical housing, the housing is divided into left and right sections along an axial direction, the right section is internally provided with a tension sensor and a temperature sensor, and the left section is internally provided with a communication circuit configured to output sensor monitoring data; the housing is provided with a through hole along the axial direction, the through hole is the via hole of the contact net cable, and the two ends of the through hole are provided with a clamp; and an antenna configured to monitor wireless transmission of data is arranged at the external portion of the left section of the housing. The contact net tension monitoring device is simple in structure, easy to use and substantial in technology effect, can be widely applied to occasions of contact net cable product design online monitoring to satisfy field environment work requirement of a contact net system, realize real-time monitoring of tension (stress) and temperature of the contact net and provide reliable, accurate and comprehensive monitoring data.

Description

technical field [0001] The invention relates to the technical field of electrified railway catenary monitoring, in particular to a catenary tension monitoring device. 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 operation. Its mechanical ...
