Abstract
The utility model discloses a windage-yaw-preventing suspension-type combined insulator including an insulating core rod, a silicon rubber umbrella sleeve and fixed assemblies fixed on two ends of the insulating core rod. The silicon rubber umbrella sleeve is coupled with the outer wall of the insulating core rod. The insulating core rod is in a structure of a solid rod. The silicon rubber umbrella sleeve is coupled with the outer wall of the insulating core rod by adopting an integral injection vulcanization technique. The fixed assemblies are fixed on the two ends of the insulating core rod by adopting a pressing joint method. The windage-yaw-preventing suspension-type combined insulator provided by the utility model is characterized in that the number of components is reduced while guaranteeing the anti-bending strength; the structure is simple; a probability of the existence of bulbs in a boundary is reduced substantially by adopting the integral injection vulcanization technique, and accidents that the boundary is struck through when an electric field is over-high are prevented; and the service life and safety performance of the windage-yaw-preventing suspension-type combined insulator are improved.
Description
Technical field
The utility model relates to power domain, is meant the compound suspension insulator of a kind of anti-windage yaw especially.
Background technology
Flourish along with China's power domain, electric pole is widely used in power domain, also extensively applies on the electric pole, in order to securing electric lines at the compound suspension insulator of supporting electric wire this part; Prevent electric wire under the interference of wind, the trolley wire bar, the compound suspension insulator of existing anti-windage yaw is made up of three parts of fixation kit at insulation mandrel, silicon rod glue umbrella cover and two ends; And scribble coupling agent at mandrel surface, the silicon rubber umbrella cover is socketed on the plug outer wall, and contact-making surface between the two is the interface; This spline structure is provided with, and usually there is bubble in the interface, under the excessive situation of electric field; Cause the interface breakdown, cause the useful life of the compound suspension insulator of whole anti-windage yaw shorter, particularly under the situation of the above electric pressure of 110KV; Requirement of strength to insulator is very big, and the compound suspension insulator of existing anti-windage yaw adopts two joint versions, the middle flange ways of connecting that adopts; Such complex structure causes manufacturing cost higher, and security performance reduces.
The utility model content
To the deficiency that prior art exists, the purpose of the utility model is to provide a kind of simple in structure and compound suspension insulator that manufacturing cost is lower.
For realizing above-mentioned purpose; The utility model provides following technical scheme: the compound suspension insulator of a kind of anti-windage yaw; Comprise insulation mandrel, silicon rubber umbrella cover and be fixed in the fixation kit at insulation mandrel two ends; Described silicon rubber umbrella cover is coupled to the insulation mandrel outer wall; It is characterized in that: described insulation mandrel is the solid bar structure, and described silicon rubber umbrella cover vulcanizes the outer wall that is coupled to insulation mandrel through general injection, and described fixation kit is also fixed through the mode of crimping and the two ends of insulation mandrel.
Through adopting technique scheme; When guaranteeing compression strength, a plurality of parts have been reduced; And it is simple in structure; Use crimping to connect and greatly reduce the probability that is prone to exist bubble on the interface, and prevent the breakdown accident in interface when electric field is excessive, improved the useful life and the security performance of the compound suspension insulator of anti-windage yaw.
The utility model further is set to: described fixation kit comprises flange and connects bulb.
Wherein, described connection bulb comprises fixed part, bulb and connects the connecting portion of fixed part and bulb respectively that described fixed part is sheathed on an end of plug.
Through adopting technique scheme, adopt the connected mode of flange fairly simple, and the connection bulb is easy to securing electric lines.
Described connection bulb comprises fixed part, bulb and connects the connecting portion of fixed part and bulb respectively that described fixed part is sheathed on an end of plug.
The utility model further is set to: described flange surface is provided with through hole.
Through adopting technique scheme, the through hole gram of setting supplies to confine screw and passes, and is easy to processing, and is fixing relatively more firm.
The utility model further is set to: described silicon rubber umbrella cover surface is provided with a plurality of full skirts.
Through adopting technique scheme, increased creepage distance, improved insulation property greatly.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work property, can also obtain other accompanying drawing according to these accompanying drawings.
