Description

Lightning protection column type porcelain insulator with fault indication

Technical Field

The invention relates to the technical field of porcelain insulators, in particular to a lightning protection column type porcelain insulator with a fault indication function.

Background

The insulator is a special insulating control and can play an important role in an overhead transmission line. Early-year insulators are mostly used for telegraph poles, and a plurality of disc-shaped insulators are hung at one end of a high-voltage wire connecting tower which is gradually developed, are used for increasing creepage distance and are usually made of glass or ceramics, namely insulators.

Through retrieval, the patent with the publication number of CN212322745U discloses a lightning protection column type porcelain insulator with fault indication, and the device realizes the effect of dual indication from the visual sense and the auditory sense by arranging a small bell and a filling nail, and is convenient for a worker to quickly find out the insulator to be maintained.

The existing device is the same as the fixing mode of the conventional porcelain insulator, the device is bound outside the electric wire by winding an external metal strip, the fixing mode causes that a worker cannot replace the insulator quickly and conveniently when finding the fault insulator, and the worker has to replace and install the insulator by using a safety rope as a fulcrum through two hands due to complicated dismounting modes, so that the safety of the worker cannot be guaranteed, moreover, the insulator fails and is generated due to excessive impurities on the surface of the insulator, so the worker needs to clean the outer surface of the device, the existing method mostly adopts cleaning cloth to clean, but most of the insulators are vertically hung on a cable, so the worker can have danger when cleaning the lower part of the insulator, and other existing insulator cleaning devices adopt a climbing robot to carry out spiral motion cleaning, however, the design requires two hands to be matched and can not be operated by one hand, in addition, the climbing robot is expensive, and the insulator is generally used in a high-voltage transmission line, so that the interference of the strong magnetic field is serious, the design of the climbing robot has high requirements, and the stability of the climbing robot is low.

In view of the above, we propose a lightning protection column type porcelain insulator with fault indication.
