Abstract
The utility model discloses an outdoor resin insulator which comprises a body. The body is divided into an upper portion and a lower portion, the upper and lower portions are trapezoid and in mirror symmetry, an upper insert is arranged in the upper portion of the body, and a lower insert is arranged in the lower portion of the body. The body is made of an epoxy resin. The middle portion of the body is the round edge, and the upper side of the round edge is the hexagon edge. The outdoor resin insulator has the advantages that the mechanical strength and the insulating strength are high and the insulation protection between high voltage lines and the ground in underground running lines is facilitated.
Description
Technical field
The utility model relates to a kind of insulator in the appliance field, particularly the outdoor resin insulator in a kind of subway power circuit.
Background technology
Insulator is commonly called as porcelain vase, and it is the insulator of supporting wire.Insulator can guarantee that wire and cross-arm, shaft tower have enough insulation, and it is in operation and should be able to bears the loading of wire vertical direction and the pulling force of horizontal direction.It is also standing Exposure to Sunlight, drench with rain, the corrosion of climate change and chemical substance.Therefore, insulator should have good electric property, and enough mechanical strengths are arranged again.The quality of insulator is very important to the safe operation of circuit.At present, the insulator of using in the subway line all is that porcelain is done, and frangible when installing and using, bending strength is low, and dielectric strength is low, in order to overcome above defective, is necessary to make improvements.
The utility model content
The utility model provides a kind of outdoor resin insulator, compares with original technology, and is non-friable, lightweight, and the product mechanical strength is high, and dielectric strength is good, is beneficial in the subway circulation circuit high-tension line and ground insulation are adequately protected.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to provide a kind of outdoor resin insulator, comprise body, described body is divided into part and lower part, described upper part and bottom are divided into trapezoidal shape and mirror image is symmetrical, wherein, be provided with inserts in the upper part of described body, be provided with lower inserts in the lower part of described body.
Above-mentioned outdoor resin insulator, wherein, described body is made by epoxy resin.
Above-mentioned outdoor resin insulator, wherein, the middle part of described body is circular edge, the upside of described circular edge is the hexagon edge.
Above-mentioned outdoor resin insulator, wherein, described upper inserts and lower inserts are stainless upper inserts and lower inserts.
Above-mentioned outdoor resin insulator wherein, arranges projection (4) and groove on the surface of described upper inserts and lower inserts.
The utility model contrast prior art has following beneficial effect: the outdoor resin insulator that the utility model provides; inserts and lower inserts are set in the body; and upper inserts and lower inserts are made by stainless steel; non-friable; lightweight, body is made by the epoxy resin material, and mechanical strength is high; dielectric strength is good, is beneficial to the protection to high-tension line and ground insulation in the subway circulation circuit.
Description of drawings
