Wire type live line measurement method

Abstract

The invention relates to a wire type live line measurement method and a dedicated testing ruler, belonging to the technical field of power supply overhauling and maintenance. The technical scheme is as follows: the ruler comprises a body (4), slots (2), a permanent magnet (1) and an insulating tension pole connecting mechanism (3), wherein the body is a rectangular insulating plate; two sides of the rectangular insulating plate in the length direction are provided with a plurality of slots; the width of each slot is matched with the diameter of one type of wires; the end of the rectangular insulating plate in the width direction is provided with the permanent magnet; the other end in the width direction is provided with the insulating tension pole connecting mechanism. The ruler disclosed by the invention has the beneficial effects that the slots are processed according to the wire diameter strictly; the measured wires with steel-cored aluminum strands are arranged at one side while the measured wires without steel-cored aluminum strands are arranged at the other side, and the wires are distinguished by number and colors, which is clear at a glance; the result is accurate; the measurement can be performed in a live state without cutting off the power, and the production can not be influenced; and by carrying out actual live line measurement on different lines, the use is more convenient and the wire type measurement is more accurate.

Description

technical field [0001] The invention relates to a method for measuring live wire type and belongs to the technical field of power supply maintenance. Background technique [0002] Due to the long service life of the power supply system, the original data on some old wire models may be lost or lost, or the existing data is obviously inconsistent with the actual line model, or cannot be confirmed. In the process of planned maintenance or temporary power outage, due to the heavy workload, it is too late to use the vernier caliper to measure one by one. At the same time, the vernier caliper is inconvenient to carry; especially when the line runs for a long time and stretches due to tension, some key parts cannot be measured. In place, this work is arranged separately, and a power outage is required, which affects the reliability of power supply. Contents of the invention [0003] The purpose of the present invention is to provide a live wire measurement method, which can comp...
