An ice-melting composite insulator comprises a common composite insulator skirt and an ice-melting skirt, wherein the ice-melting skirt is a material layer used for melting the surface ice layer on the insulator and is arranged on the surface of the common composite insulator skirt. The material layer for melting the surface ice layer of the insulator is a semiconductor coating layer. The utility model aims at the special operation requirements of power lines in icing regions, improves the skirt structure and surface material of the insulator and enables the insulator to be anti-icing and have automatic ice-melting function after icing. The ice-melting composite insulator sufficiently utilizes the special structure of the composite insulator skirt and the spontaneous heating property of the composite material in special occasions to guarantee the anti-icing and automatic ice-melting properties of the insulator, accordingly avoids overloading and ice flashover trip accidents and is beneficial to safe operation of lines.
Description
Technical field
The utility model relates to the composite insulator that uses in a kind of power transmission and transformation technical field.
Background technology
Icing accumulated snow is common natural phenomena.For transmission line, icing accumulated snow can cause serious accident.China is one of the most serious country of powerline ice-covering in the world, has caused a lot of accidents over the years, and wherein main is, and icing causes that insulator is scurried flashover, and the icing overload causes that shaft tower collapses and wire fracture, damage.Behind the covering ice for insulator except that causing the mechanical breakdown, because covering ice for insulator or be bridged the back leakage distance and shorten, and during ice-melt, icing insulator surface resistance significantly reduces, thereby cause flashover fault, and the sustained arc insulator of also may burning in flashover fault causes that insulator damages and electrical strength reduces.China in recent decades large tracts of land ice damage accident happen occasionally, at present electrical production, run unit are just extensively explored anti-ice damage, are prevented the measure of icing.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of can effectively prevent the circuit overload that the line insulator icing causes and the generation of flashover fault, guarantees the ice-melt type composite insulator of electric power netting safe running.
The technical solution of the utility model is: a kind of ice-melt type composite insulator, comprise common composite insulator full skirt, and on described common composite insulator full skirt surface the material layer that melts the insulator surface ice sheet is arranged, become the ice-melt full skirt.The material of common composite insulator is the silastic elastomer material.
The described material layer that melts the insulator surface ice sheet is the semi-conductive coating layer.
Described ice-melt full skirt can melt ice sheet under the situation of energising.
The utility model is coated semi-conductive coating at the specific (special) requirements of the regional transmission line operation that icing is arranged in the compound inslation sub-surface, has improved the umbrella skirt construction and the surfacing of insulator, make its can be anti-icing and freeze after initiatively ice-melt.The utility model has made full use of the performance of semi-conductive coating energising back heating, utilized the spontaneous hot of the special construction of composite insulator full skirt and composite material special occasions, guarantee the anti-icing and autonomous ice-melt of performance composite insulator, thereby avoid transshipping and icing the generation of dodging the tripping operation accident, help the line security operation.
Description of drawings
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Embodiment
Among Fig. 1, Fig. 2, on common composite insulator full skirt 1 surface the material layer that melts the insulator surface ice sheet is arranged, this material layer is to be coated with the semi-conductive coating layer 2 that semi-conductive coating forms on common composite insulator full skirt 1 surface.
Claims (2)
1. an ice-melt type composite insulator comprises common composite insulator full skirt (1), it is characterized in that: described common composite insulator full skirt (1) has the material layer that melts the insulator surface ice sheet on the surface.
