Abstract

The invention discloses an insulation assembly. The insulation assembly comprises an insulation sleeve which is provided with a first end and a second end opposite to the first end; and an insulation umbrella skirt which is formed on the outer wall of the insulation sleeve. The insulation assembly further comprises an insulation pedestal made of an insulation material, and the insulation pedestal is connected to the first end of the insulation sleeve. According to the invention, a conventional metal flange is replaced by the insulation pedestal, and thus the manufacturing cost of the insulation assembly is decreased. Besides, the boning strength between the insulation pedestal and the insulation sleeve is good, slits are not easily generated between the two, and the sealing performance of the insulation assembly is improved. Furthermore, the insulation pedestal can effectively prolongs the creepage distance and dry-arc distance of the insulation assembly, can substantially improve the electric field distribution of the insulation assembly and optimizes the electrical performance of the insulation assembly.

Description

technical field [0001] The invention relates to an insulating assembly. Background technique [0002] In the electrical power industry, it is often necessary to use electrically isolated insulating components (or simply insulators). [0003] In the prior art, the insulation assembly usually includes an insulation sleeve, an insulation umbrella group and a metal flange. In the prior art, the cost of the metal flange is relatively high, which increases the manufacturing cost of the insulating assembly. In addition, due to the different materials of the metal flange and the insulating sleeve, the thermal expansion coefficients of the two are different, resulting in a gap between the two, and the SF6 gas filled in the insulating sleeve is easy to flow from the gap between the metal flange and the insulating sleeve. The gap leaked out. [0004] In addition, in the prior art, metal flanges have disadvantages such as heavy weight and reduced electrical performance of insulating ...
