Abstract

The invention relates to a cable vibration monitoring device and system. The cable vibration monitoring device is provided with an insulating shell, an elastic assembly, a capacitor assembly, a capacitor detection assembly and a control assembly, and when a cable vibrates, the elastic assembly pushes a second pole plate of the capacitor assembly to move relative to a first pole plate, so the distance between the first pole plate and the second pole plate is changed, and the capacitance value of the capacitor assembly is changed. The control assembly can calculate the moving distance between the first pole plate and the second pole plate through the variation of the capacitance value, namely the amplitude of the vibration cable is obtained. According to the cable vibration monitoring device provided by the embodiment of the invention, the technical problem that a vibration cable detector in the prior art can only detect the vibration frequency of the vibration cable and cannot determine the amplitude of the vibration cable is solved, and the technical effect of effectively detecting the amplitude of the vibration cable is achieved.

Description

technical field [0001] The present application relates to the technical field of power monitoring, in particular to a cable vibration monitoring device and system. Background technique [0002] The cables are usually installed outdoors, where the cables are in a state of vibration for a long time due to wind, electromagnetic effects between cables, etc. The cable is one of the important equipment in the power system, and its vibration characteristics are the key factors affecting the stable operation of the power system. Therefore, it is necessary to monitor the vibration characteristics of the cable in real time. [0003] At present, the monitoring of the cable vibration characteristics mainly adopts the electromagnetic induction vibration cable detector. When in use, the coil of the vibration cable detector is set on the outer periphery of the vibration cable, and the coil is energized to generate an electromagnetic field, and the vibration cable and the coil move relative...
