Composite insulator climbing system

Abstract

The invention discloses a composite insulator climbing system which comprises an encircling type frame capable of being opened and closed, an opening, closing and locking mechanism, a moving mechanism and a battery control cabinet. An umbrella skirt of an insulator is wrapped with the encircling type frame. The opening, closing and locking mechanism is arranged outside of the encircling type frame and controls the encircling type frame to be opened, closed and locked. The moving mechanism is fixed to the encircling type frame and drives the encircling type frame to move along an insulator chain. The battery control cabinet is fixed to the encircling type frame and provides power for the moving mechanism, a detection mechanism and the opening, closing and locking mechanism. According to the composite insulator climbing system, a shifting wheel shifts continuously, an up-down traveling mode is adopted, the moving speed is high, the operation efficiency is high, the operation time is shortened, and the operation cost is reduced easily; automatic opening and closing are achieved through rotation of a motor, and thus the online and offline operation difficulty is lowered easily.

Description

technical field [0001] The invention relates to a composite insulator climbing system. Background technique [0002] Composite insulators have been widely used in power systems due to their light weight, high strength, strong pollution flashover resistance, and convenient manufacturing and maintenance, breaking the long-term dominance of porcelain and glass insulators. With the popularization and use of composite insulators in power systems and the increase of service life, the aging problem of insulators has become more and more prominent. Throughout the country, there have been many failures of composite insulators, many composite insulators have abnormal heating phenomena, and many composite insulator fracture accidents have also occurred. However, since the structure and materials used of composite insulators are different from ordinary insulators, how to track and monitor the operation status of composite insulators and how to clean them are urgent problems to be solve...

However, since the structure and materials of composite insulators are different from ordinary insulators, how to track and monitor the operation status of composite insulators and how to clean them are problems that need to be solved urgently.

[0003] Patent CN203376421U introduces the realization of a principle and method of electric field detection, but does not provide an effective moving mechanism, while patent CN103822854A mainly introduces an auxiliary operating rod of a hydrophobicity detection device, and the hydrophobicity detection method mainly judges the outer surface of composite insulators. Surface defects, internal defects of composite insulators cannot be detected

[0004] The existing vertical insulator detection and decontamination robot, the climbing mechanism is not perfect, and the climbing mechanism has too high requirements on the shape and position error of the insulator string, and it is easy to damage the antifouling coating on the surface of the insulator. Some climbing mechanisms are bulky and complicated to install, and it is very difficult to install them on the insulator string, wasting valuable work time
