Combined insulator for power distribution

Abstract

The invention discloses a combined insulator for power distribution. The combined insulator comprises a round core rod, wherein an external threaded sleeve is fixedly arranged on the round core rod, the external threaded sleeve is in threaded connection by the round core rod, a fixed ring and a pull ring are conveniently limited at two ends of the external threaded sleeve, a group of positioning rods are arranged at a right side wall of the fixed ring and are arranged opposite to each other, a first screw rod is fixedly arranged at a right end of each positioning rod, a fixed disc and a silicon rubber insulation umbrella conveniently and movably sleeve the first screw rod by the first screw rod, meanwhile, a left side wall of the fixed disc is extruded on a right side wall of the positioning rod, and the fixed disc can be limited; and by arranging a positioning sleeve at an inner side of the fixed disc, the first screw rod and a second screw rod are conveniently in threaded connectionwith two ends of the positioning sleeve, a pull rod is inserted to the pull ring, and the group of fixed rings arranged opposite to each other and the silicon rubber insulation umbrella are conveniently limited and fixed between the fixed ring and the pull ring under matching of the second screw rod and a limitation baffle disc.

Description

technical field [0001] The invention relates to the related technical field of insulators, in particular to a combined insulator for power distribution. Background technique [0002] Post insulators are indispensable accessories in power distribution. Post insulators play an important role in overhead transmission lines. They are usually made of silica gel or ceramics. They play the role of supporting wires and preventing current from returning to the ground. This function must be guaranteed, otherwise the service life and operating life of the entire line will be damaged. [0003] The structure of the existing post insulator is relatively simple. The silicone rubber insulating umbrella cover and the circular mandrel on the post insulator are all of an integrated structure. Due to the integrated structure, the post insulator has defects in actual use: when the silicone rubber insulating umbrella If any one of the sleeve and the round mandrel is damaged, both must be replace...

AI Technical Summary

Problems solved by technology

[0003] The existing post insulator has a relatively simple structure. The silicone rubber insulating sheath and the circular mandrel on the post insulator are of an integrated structure. Due to the integrated structure, the post insulator has defects in actual use: when the silicone rubber insulating umbrella Any one of the sleeve and the round mandrel is damaged, so that both have to be replaced, which increases the cost. Therefore, a combined insulator for power distribution is proposed
