Special-purpose zero value detection tool for insulator of power transmission line

Abstract

The invention relates to a special-purpose zero value detection tool for an insulator of a power transmission line. The tool comprises an intelligent detector, a telescopic rod is mounted at one side of the intelligent detector, one end of the telescopic rod is connected with the intelligent detector, the other end of the telescopic rod is connected with a probe connection board, the probe connection board is hinged to the telescopic rod, the lateral part of the probe connection board is provided with two probes, and the two probes are connected with a lead. According to the special-purpose zero value detection tool, time of zero value detector for the insulator is reduced, on-tower workers are reduced, the utilization rate of staff is improved, and the working efficiency is improved; the on-tower workers need no operation outside the insulator, the detention time and operation risk of high-altitude work of the workers are reduced, and the safety level of work is improved.

Description

technical field [0001] The invention relates to a special tool for zero value detection, in particular to a special tool for zero value detection of transmission line insulators. Background technique [0002] The zero value detection of insulators in transmission lines is one of the important tasks to ensure the safe and stable operation of transmission lines. Convenient, fast, accurate and efficient detection of insulator zero value has always been the focus and difficulty of line operation and maintenance. The existing insulator zero value detection device is composed of three major parts, namely an insulation detection rod, a connecting wire and a detector, and more than 3 staff members are required to work on the tower at the same time during detection. The length of the insulation detection rod is short, and the porcelain bottle needs to be removed for operation during detection, which has a low safety factor; the connecting wire is an ordinary copper wire, and the len...

AI Technical Summary

Problems solved by technology

The length of the insulation detection rod is short, and the porcelain bottle needs to be removed for operation during detection, which has a low safety factor; the connecting wire is an ordinary copper wire, and the length required to meet the measurement requirements is longer, and it must be placed on the tower every time it works. It is easy to cause disordered lines; the zero value detection is generally carried out in good weather. Due to the sun, the reflective readings on the instrument panel are not easy to read; Place it horizontally, otherwise it will affect the numerical indication and cause misjudgment, and it is difficult to find a stable and horizontal place for the uneven angle steel of the iron tower

These have greatly extended the working time on the tower, increased the complexity and danger of the work
