Problems solved by technology

At present, the measurement of the near-end electrical distance needs to be carried out through the use of a steel tape and an operating rod. This method cannot be read directly. It needs to be marked on the operating rod, and then use the steel tape to measure and mark after the tower is on or off the tower. The marked distance at the location, the cumbersome measurement operation steps are easy to make the error value superimpose, and finally lead to the distortion of the measurement result, and consume a lot of working time
However, there is still no safe and reliable measurement method for the measurement of the remote electrical distance

Abstract

The invention discloses a power transmission line near-end and far-end electric distance measurement device. The top end of a measurement rod is provided with a contact terminal, the bottom end of the measurement rod is provided with a handle, a rod body of the measurement rod is provided with scale, and the rod body of the measurement rod is successively provided with different-color warning color blocks for warning a safety distance from the top end to the bottom end. A far-end auxiliary measurement rod is a telescopic rod, the top end of the far-end auxiliary measurement rod is provided with an internal thread hole extending along the axis of the far-end auxiliary measurement rod, a connecting anchor ear is an anchor ear having an adjustable hole pitch, and the connecting anchor ear is provided with an external threaded rod matching the internal threaded hole of the far-end auxiliary measurement rod. The device is convenient to carry, has the advantages of simple operation and an accurate measurement result, and has the advantage that whether the measurement result is qualified is easy to determine; and the device can shorten operation time, reduce labor intensity, improve working efficiency and the work personnel's personal safety factor, and overcome the problem that a far-end electric distance cannot be measured in an electrified manner.

Description

technical field [0001] The invention relates to a tool for maintenance and acceptance of a power transmission line, in particular to a measuring device for measuring the electrical distance between the near and far ends of a power transmission line. Background technique [0002] In recent years, due to the intensification of power grid construction, the acceptance tasks of new lines and technically upgraded lines are arduous, and defects of insufficient electrical distances are often seen in the acceptance, so accurate measurement of various electrical distances is particularly important for the safe and stable operation of lines. At present, the measurement of the near-end electrical distance needs to be carried out through the use of a steel tape and an operating rod. This method cannot be read directly. It needs to be marked on the operating rod, and then use the steel tape to measure and mark after the tower is on or off the tower. The marked distance at the place, the c...
