Composite suspension type silicon rubber insulator structure

Abstract

The invention discloses a composite suspension type silicon rubber insulator structure. The composite suspension type silicon rubber insulator structure comprises a supporting core body and a composite outer sleeve, wherein a winding binding head and a mounting base frame are fixedly mounted at two ends of the supporting core body respectively; the winding binding head is made of glass fiber epoxyresin ceramic; the composite outer sleeve is made of silicon rubber; the composite outer sleeve covers the outer surface of the supporting core body; annular bulges are arranged at connecting parts of the supporting core body, the winding binding head and the mounting base frame; outer surfaces of the annular bulges are covered with silicon rubber ring sleeves; umbrella skirts are fixedly mountedon the outer surface of the supporting core body; a step type lap joint structure is arranged between each two adjacent umbrella skirts; a lap joint ring is fixedly mounted at the outer edge of eachumbrella skirt; a differentiation structure is adopted so that a creepage distance is not limited by the distance between the umbrella skirts; while the self insulating capability is improved, point discharge also can be prevented, so that the insulating capability is greatly improved; an umbrella skirt structure is improved so that the transverse mechanical property is improved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a composite suspension silicone rubber insulator structure. Background technique [0002] In the early years, insulators were mostly used on utility poles, and gradually developed into high-voltage wire connection towers where many disc-shaped insulators were hung at one end. It was used to increase the creepage distance, usually made of glass or ceramics, and was called an insulator. Insulators play two basic roles in overhead transmission lines, namely supporting wires and preventing current from returning to the ground. These two functions must be guaranteed. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions. Otherwise, the insulator will not play a significant role, and it will damage the service life and operating life of the entire line. [0003] Most of the current composit...

AI Technical Summary

Problems solved by technology

[0005] (1) In the existing technical means, the creepage distance of the insulator is always limited by the sheds, that is to say, the creepage distance is always limited by the distance between the sheds;

[0006] (2) In the application of insulators, their insulation needs to be further improved. In particular, in harsh application environments or ultra-high loads, the insulation of insulators is not fully guaranteed, and there is a risk of high voltage leakage;

[0007] (3) The mechanical properties of insulators such as installation stability and lateral tensile resistance need to be further improved, especially for installations with large creepage distance requirements, this process is limited
