The invention relates to the field of high-voltage power transmission and transformation, particularly to a flexible assembly for high-voltage cable power transmission. The flexible assembly for high-voltage cable power transmission comprises an insulator fixing component and a cable directing component, wherein the insulator fixing component comprises an upper fixing plate and a lower fixing plate which are matched and connected with each other, a mounting through hole for fixing an insulator is formed at the center of each of the upper fixing plate and the lower fixing plate, a flashover preventing shield is arranged at the top of the upper fixing plate, first linear slots which are evenly distributed in parallel are formed at the top of the upper fixing plate, a T-shaped slot is formed at the bottom of the upper fixing plate and is internally provided with a fastening bolt which can slide relative to the T-shaped slot, the cable directing component comprises a left arc-shaped plate and a right linear slot plate which are integrated into a whole, second linear slots are arranged at the top of the right linear slot plate, a through hole is formed at the left end of the left arc-shaped plate, the fastening bolt is bolted to a fastening nut after passing through the through hole, and finally the fastening nut is screwed down to connect and fix the insulator fixing component and the cable directing component together. The flexible assembly for high-voltage cable power transmission is simple in structure; with adoption of the flexible assembly, a high-voltage cable can be bent flexibly and bird damage can be prevented.
Description
technical field [0001] The invention relates to the field of high-voltage power transmission and transformation, in particular to high-voltage cable power transmission bending components. Background technique [0002] Ceramic insulators are an important part of substations and high-voltage transmission lines. The main function is to connect high-voltage cables to the brackets for insulation, mechanical connection and support. In the prior art, usually, the high-voltage cable is directly connected to the groove at one end of the ceramic insulator, or is wound between the sheds of the ceramic insulator. In this connection mode, the general high-voltage cables can only be connected in a straight line through the ceramic insulator, and cannot be turned to meet different environmental requirements; in addition, the ceramic insulator is exposed to the outside, and it is easy to cause flashover due to bird pecking or bird droppings. Eventually, the circuit will be blacked out. C...
