Embodiment Construction

[0015] Examples of shock-resistant bushing devices are figure 2 As shown: it includes a bracket 4, a metal sleeve and a vertically arranged insulating sleeve 1. The metal sleeve includes a vertically arranged sleeve connecting cylinder 3 and a support cylinder 6 extending axially along the front and rear directions. The support cylinder 6 Welding and fixing on the casing connecting cylinder 3, the metal sleeve is made of an aluminum alloy plate with a wall thickness of 12mm, that is to say, the metal sleeve is a thin-walled shell structure, which makes the metal sleeve deformable, and The aluminum alloy material can further increase the toughness of the metal sleeve, and the rigidity of the metal sleeve is less than that of the bracket. The coaxial line of the insulating sleeve is fixed on the upper end of the sleeve connecting cylinder, and the lower end of the sleeve connecting cylinder is fixed on the upper end of the bracket. The bracket includes a vertically arranged bra...

Abstract

The invention relates to an anti-knock type sleeve device and application thereof. The anti-knock type sleeve device comprises a support, a metal sleeve and an insulation sleeve; the lower end of the insulation sleeve is fixed to the upper end of the metal sleeve, the rigidity of the metal sleeve is smaller than the rigidity of the support, and the lower end of the metal sleeve is fixedly connected with the support, so that shocks of the support to the insulation sleeve are buffered through self deformation of the metal sleeve during earthquakes. By means of the anti-knock type sleeve device and the application of the anti-knock type sleeve device, the problem that in the prior art, the lower end of the insulation sleeve is larger so that the insulation sleeve is prone to breakage during the earthquakes is solved.

Description

technical field [0001] The invention relates to an anti-seismic bushing device and its application. Background technique [0002] The bushing device is located at the end of the (H)GIS equipment and needs to be connected upward to the overhead line of the power station, and downward to the (H)GIS. It bears multiple functions of high voltage insulation load, mechanical load and insulation support. Therefore, the operation stability of the casing device will directly affect the stability of the overall operation of (H)GIS equipment. Once the casing device has a problem, it will definitely affect the operation of the entire power grid, which will bring huge losses to the society and the people. When the casing device is used in non-seismic areas, there will be no problems. However, when the casing device is used in areas with frequent and strong seismic activities such as Qinghai-Tibet and Tianshan, higher requirements are put forward for its operational stability. Casing devi...
