The invention provides a verification unit and method of a transmission line breeze vibration monitoring device. By connecting the verification unit to the measurement circuit of the transmission line breeze vibration monitoring device, the switching switch in the verification unit is controlled to control the transmission line breeze vibration Different parts of the monitoring device switch to different verification methods, and conduct an overall functional verification of the transmission line breeze vibration monitoring device, so as to ensure that when the test data of the transmission line breeze vibration monitoring device is unreliable, the staff can timely carry out transmission line breeze vibration monitoring Equipment adjustment and maintenance. The verification unit includes: a verification sensor, which is used to collect data of transmission line breeze vibration; a verification resistance unit, which includes 4 resistors with the same resistance value, and is connected in parallel to the measurement circuit of the transmission line breeze vibration monitoring device; switch, used for The control check sensor or the check resistor is connected to the measurement circuit of the transmission line breeze vibration monitoring device.
Description
technical field [0001] The invention belongs to the field of on-line monitoring of transmission lines, and more specifically relates to a verification unit and method of a transmission line breeze vibration monitoring device. Background technique [0002] When the transmission line is blown by the breeze, it will generate periodic vibrations. If no anti-vibration measures are taken, it may lead to fatigue and broken strands of the wires, which will seriously affect the safety of the line. At present, the power production part generally uses the wind vibration monitoring device of the transmission line to measure and monitor the vibration of the transmission line in real time, so as to select the appropriate anti-vibration measures. However, at the present stage, the reliability of the measurement results of the transmission line breeze vibration monitoring device for the vibration of the conductor cannot be effectively guaranteed. The reason is that wind vibration monitorin...
