Rotation type three-proofing insulator

Abstract

The invention relates to a rotation type three-proofing insulator which comprises a fixed handle, suspension shafts, an insulator umbrella skirt and a suspension line handle. The fixed handle is mounted at the upper end of the upper suspension shaft, and the lower end of the upper suspension shaft is rotatably arranged inside an upper rotating shaft. The suspension line handle is mounted at the lower end of the lower suspension shaft, and the upper end of the lower suspension shaft is rotatably mounted inside a lower rotation shaft. The upper rotating shaft and the lower rotating shaft are coaxially connected through a connecting shaft, and a rotating blade and the insulator umbrella skirt are coaxially mounted on the connecting shaft between the upper rotating shaft and the lower rotating shaft. The rotation type three-proofing insulator is scientific in design, reasonable in structure, easy to manufacture and convenient to use. Except for the basic functions of the insulator, the functions of fouling proofing, windage yaw proofing and ice coating proofing are achieved by the insulator through the effects of natural force and centrifugal force, and the purposes of improving the safety level of the insulator in a power grid and saving maintenance cost are achieved.

Description

technical field [0001] The invention relates to an insulator used for fixing lines and insulating in the field of power grid transmission equipment, in particular to a rotary three-proof insulator.

Problems solved by technology

Dust is easy to deposit on the surface of conventional insulators, and it is unevenly distributed on the shed of the insulator. Under adverse conditions such as fog, dew, and drizzle, flashover may occur on dirty insulators under low voltage. Insulation flashover accidents caused by pollution It is one of the main forms of power grid accidents, which has caused major economic losses to people's production and life every year; the wind-biased grounding of insulators means that the suspension insulators deviate from the vertical position to the iron tower body under strong wind conditions and cause a certain phase line to be grounded. In recent years, many such accidents have occurred on lines above 110kV, seriously affecting and threatening the safe operation of the power grid system; insulators in snowy weather are often covered with ice and snow, which increases the possibility of flashover grounding of insulators and poses a serious threat to the safe operation of the power grid

[0003] At present, insulators for high-voltage overhead lines in the power grid are basically divided into two types: pillar type and suspension type. Strengthening measures in the three aspects of coatings requires a lot of manpower, material and financial resources

In addition, there are currently no insulators with wind deflection resistance
