An insulation string detection device

Abstract

The invention discloses an insulator string detection device. The insulator string detection device comprises a cage, a walking mechanism, a detection mechanism and a control mechanism, wherein the cage encircles an insulator string, and the walking mechanism, the detection mechanism and the control mechanism are fixedly arranged on the cage. The cage comprises an upper cage body and a lower cage body, one side of the lower cage body is hinged to the upper cage body, and the other side of the lower cage body is connected with the upper cage body through a buckle in a buckled mode. The walking mechanism comprises a walking motor, a walking shifting piece and a storage battery, wherein the walking motor is fixedly arranged on the upper cage body, the walking shifting piece is fixedly arranged on the output shaft of the walking motor, and the storage battery is used for supplying power to the walking motor. According to the insulator string detection device, a mechanical mechanism is adopted to drive a detection head to walk on the insulator string and drive the detection head to carry out detection, and the previous method that an electrician on a tower connects a liver insulator tester to one end of an insulation operation rod, the electrician holds the other end of the insulation operation rod by hand to carry out live detection on tension support porcelain insulators one by one is changed; the purposes of saving time and labor and being safe are achieved.

Description

technical field [0001] The invention relates to a live detection device for transverse porcelain insulators used in tension towers of high-voltage transmission lines. Background technique [0002] Insulators are insulation equipment used between towers and conductors of high-voltage overhead transmission lines. In order to prevent accidents caused by problems with insulators, frequent inspections are required. When testing the porcelain insulators on the tension tower of the transmission line, if the electrician on the tower uses the operating rod to detect the porcelain insulators, the physical strength of the electrician on the tower is high; because the insulation operating rod needs to be held horizontally by the electrician on the tower to inspect the porcelain insulators one by one , and the 500KV line tension tower porcelain insulator live detection uses an insulating operating rod with a length of 5.5 meters to 7.5 meters. Holding such a long insulating operating rod...

AI Technical Summary

Problems solved by technology

When testing the porcelain insulators on the tension tower of the transmission line, if the electrician on the tower uses the operating rod to detect the porcelain insulators, the physical strength of the electrician on the tower is high; because the insulation operating rod needs to be held horizontally by the electrician on the tower to inspect the porcelain insulators one by one , while the 500KV line tension tower porcelain insulator live detection uses an insulating operating rod with a length of 5.5 meters to 7.5 meters. Holding such a long insulating operating rod horizontally to detect the porcelain insulators piece by piece, the electrician on the tower consumes a lot of physical strength

At present, with the serious air pollution and the improvement of the insulation level of transmission lines, the number of tensile tower porcelain insulators of some 500KV transmission lines has increased from 32 to 42, and the length is about 8 meters, which makes it very difficult to use the operating rod to detect. High labor intensity and high-altitude operations are very dangerous
