Automatic measuring device for pole and tower electric transmission line jumper sag

Abstract

The invention provides an automatic measuring device for a pole and tower electric transmission line jumper sag. The automatic measuring device comprises a first power supply module, a second power supply module, and a first clamping frame and a second clamping frame which are matched with the two horizontal ends of a jumper, electric pushing rods are installed on the lower parts of the first clamping frame and the second clamping frame correspondingly, a photoelectric emission module and a photoelectric sensing module are installed at the lower ends of the two sets of electric pushing rods correspondingly, a sensing window of the photoelectric sensing module is arranged opposite to an emitting window of the photoelectric emission module, a trigger switch is arranged on the photoelectric sensing module, and connected with an infrared rangefinder which is fixed to the first clamping frame or the second clamping frame through signals, a reflecting plate is installed on the position, below the infrared rangefinder, of the end of the corresponding electric pushing rod, the upper edge plane of an emitting plate is located in the same plane as center points of the emitting window and thesensing window, a data storage device is arranged on the infrared rangefinder, and connected with the output end of the infrared rangefinder through signals. According to the automatic measuring device for the pole and tower electric transmission line jumper sag, the jumper sag can be automatically detected, the labor intensity is greatly lowered, and measured data are 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
