Problems solved by technology

The traditional falling lump compensator can judge whether the tension of the compensator at both ends is stable according to the number of falling lumps. This method is time-consuming and not intuitive and convenient; for the traditional spring compensator, it is even more impossible to judge the state of tension compensation. , such as the attenuation of tension and the failure of springs, thus causing railway safety accidents

Embodiment Construction

[0029] Such as Figure 1-3 As shown, the present invention provides a wire tension monitor, comprising a first connecting device 1 connected to one end 41 of the wire, a second connecting device 2 connected to the other end 42 of the wire, and a wire tension monitor arranged between the first connecting device and the wire. The elastic element 3 in the middle of the second connecting device, the change of the tension between one end and the other end of the thread is transmitted to the first connecting device and the second connecting device, resulting in a change in the size of the elastic element, through the The tension state of the thread is monitored through the displacement between the first connecting device and the second connecting device caused by the dimensional change of the elastic element. There is a mark on the first connecting device or the second connecting device, when there is a displacement between the first connecting device and the second connecting devic...

Abstract

The invention discloses a cable tension monitor. The cable tension monitor comprises a first connection device connected with one end of a cable, a second connection device connected with the other end of the cable, and an elastic component arranged between the first connection device and the second connection device, changes of tension between one end of the cable and the other end of the cable is transmitted to the first connection device and the second connection device so that dimensional changes of the elastic component are caused, and the tension state of the cable is monitored through displacement, generated through the dimensional changes of the elastic component, between the first connection device and the second connection device.

Description

technical field [0001] The invention relates to a tension compensation system, in particular to a tension compensation device used for tension monitoring of a cable catenary or contact wire in a power supply network of an electrified railway, which can effectively guide the maintenance personnel on site to perform simple Effective monitoring ensures the safe and reliable operation of the tension compensator. Background technique [0002] In the power supply catenary of electrified railway, under any weather conditions, the overhead cable catenary (or sling) and contact wire (or cable) should always be in a state of tension to ensure the normal operation of the power supply catenary . However, due to the influence of objective environmental conditions such as thermal expansion and contraction, the size of the cable catenary (or sling) and contact wire (or cable) will change under different climatic conditions. Therefore, tension compensators for cable catenaries or catenary...
