Jumper sag automatic measuring device for tower transmission line

Abstract

An automatic sag measurement device for jumper wires of tower transmission lines, including a first power supply module, a second power supply module, and a first clamping frame and a second clamping frame that cooperate with the horizontal ends of the jumper wire, the first clamping frame, the second Electric push rods are installed under the clamping frame, and the lower ends of the two sets of electric push rods are respectively equipped with a photoelectric emission module and a photoelectric induction module. The induction window of the photoelectric induction module is set opposite to the emission window of the photoelectric emission module. Trigger switch, the trigger switch is connected with the signal of the infrared rangefinder fixed on the first clamping frame or the second clamping frame, the end of the electric push rod below the infrared rangefinder is equipped with a reflector plate, and the upper edge plane of the launch plate is in line with the The central points of the emission window and the sensing window are located on the same plane, and the infrared range finder is provided with a data memory, which is connected to the output terminal of the infrared range finder by signal. The invention can realize the automatic detection of jumper sag, greatly reduces the labor intensity, and the measurement data is more accurate.

Description

technical field [0001] The invention relates to an auxiliary tool for a power system, in particular to an automatic sag measuring device for jumper wires of tower transmission lines. Background technique [0002] In recent years, due to frequent occurrence of local convective weather and low design standards of old lines, in power transmission lines, there have been many accidents of wind deflection and gate failure due to the discharge of towers in severe weather such as strong winds due to too long bow lines. , The long sag of the jumper has become a hidden danger that seriously affects the safe operation of the line. Retrofitting bow-zinc lines that do not meet the new design requirements of transmission lines is an important way and protective measure to ensure that wind deflection discharge faults do not occur. Therefore, in the acceptance of new lines or the construction of anti-wind deflection of old lines, it is necessary to accurately measure the sag distance of ju...

Problems solved by technology

Compared with the prior art, this invention greatly reduces the labor intensity, but it still needs to manually record the data and read the sag length, which is prone to errors, thus reducing the accuracy of the measurement data
