Problems solved by technology

This kind of insulator that glues the silicone umbrella cover to the porcelain part still has not solved the key problem of mutual cooperation between the silicone cover and the porcelain post, so it is difficult to form a large batch in production

Embodiment Construction

[0009] Below in conjunction with accompanying drawing, the utility model is described in further detail.

[0010] see figure 1 The utility model includes a porcelain column 1 and a silicone rubber umbrella cover 3 arranged on the porcelain column. The inner and outer edges of two adjacent silicone rubber umbrella covers 3 are respectively provided with concave platforms 4 and 7 that are interlocked up and down. And the glass fiber insulation layer 2 for adjustment is provided between the inner circular wall of the silicone rubber umbrella cover and the ceramic core that are interlocked with each other, and the inner edge concave platform of the silicone rubber umbrella cover is arranged at the lower or upper part of the inner edge, so The outer edge concave platform of the silicone rubber umbrella cover is set on the upper or lower part of the outer edge, and the glass fiber insulation layer for adjustment between the inner circular wall of the silicone rubber umbrella cover a...

Abstract

An insulator structure comprises a porcelain column and silicone rubber umbrella sleeves arranged on the porcelain column. The inner and outer edges of the two silicone rubber umbrella sleeves are respectively provided with concave platforms which are vertically mutually buckled, and a glass fiber insulating layer for adjustment is arranged between the inner circular walls of the mutually buckledsilicone rubber umbrella sleeves and the porcelain core. It not only solves the problem of difficult mass production, but also makes the length of the product adjustable according to the need. The arrangement of the glass fiber layer not only makes up for the deficiency of low precision of the porcelain core rod, but also improves the strength of the porcelain core rod, so that the insulator of the invention has the comprehensive mechanical properties of light weight, high rigidity, good toughness and has high anti-dirt performance.

Description

technical field [0001] The utility model relates to a high-voltage insulating element, in particular to a combined insulating structure for high-voltage power transmission and transformation. Background technique [0002] At present, most of the high-voltage post insulators used for high-voltage power transmission and transformation are all-ceramic or porcelain-silicone composite insulators. The former is heavy, has a short service life, and poor anti-pollution performance; the latter has limited mechanical strength. Although there are many studies on this at home and abroad, its structure is still not ideal. For example, a 25KV combined post insulator for electric railways proposed by British Raychem Company, it is coated with sealant on the porcelain rod and then covered with a heat-shrinkable silicone rubber umbrella cover. This structure is not only expensive, difficult to manufacture, but also difficult to apply in practice. in production. For this reason, the Chinese...
