Abstract
The utility model discloses an accessory of a strain insulator, which relates to an accessory of an insulator, and aims to solve the problems that traditional power grid line insulators are easy to have flashover phenomenon, damage power grid lines and have safety hidden hazards. The accessory comprises an outer insulation piece, a first connection piece, a second connection piece and an epoxy resin glass fiber rod; the outer insulation piece is provided with through holes along the axial direction; the through holes sequentially comprise a first large-diameter hole, a small-diameter hole and a second large-diameter hole from up to down; the epoxy resin glass fiber rod is arranged in the small-diameter hole, and both ends of the epoxy resin glass fiber rod are respectively arranged outside the small-diameter hole; the outside of one end of the epoxy resin glass fiber rod is compression jointed with the first connection piece; one end of the first connection piece is arranged in the first large-diameter hole, and the other end thereof is matched with the bowl head of the insulator in shape; the outside of the other end of the epoxy resin glass fiber rod is compression jointed with the second connection piece; and one end of the second connection piece is arranged in the second large-diameter hole. The accessory of the strain insulator is matched with the strain insulator.
Description
Technical field
The utility model relates to a kind of annex of insulator.
Background technology
The residing environmental pollution of power network line at present is serious day by day, cause power circuit to be covered with one deck dunghill with high-tension insulator, dunghill forms electric pathway on the surface of insulator, flashover takes place, pollution flashover voltage is difficult to be improved, short along the face leakage distance, very easily cause insulator to discharge over the ground, there is potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of annex of strain insulator formula insulator, to solve existing power grid line insulator the pollution flashover phenomenon takes place very easily, destroys power network line, has the problem of potential safety hazard.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: described annex is by outer insulator, first connector, second connector and epoxy glass fiber bar construction, described outer insulator has through hole vertically, described through hole is from top to bottom successively by first diametric hole, small diameter bore and second largest diametric hole constitute, described epoxy glass fiber rod is contained in the small diameter bore, and the two ends of epoxy glass fiber rod respectively are located at the outside of small diameter bore, the outside of one end of epoxy glass fiber rod and the first connector crimping, one end of first connector is located in the first diametric hole, the other end shape of first connector and insulator bowl head are complementary, the outside of the other end of epoxy glass fiber rod and the second connector crimping, an end of second connector is located in the second largest diametric hole.
The utlity model has following beneficial effect: the utility model is connected with insulator and is used the compressive resistance increased insulator, increased creepage distance, makes the insulator resistant dodge grade and strengthens, and reduces potential safety hazard.
