Abstract
The utility model relates to an insulating cross arm, the cross arm body is a hollow rectangle body, and the both ends of this rectangle body are the opening tip, the face is connected for the arc in two liang of vertical plane's junction in the rectangle body. Insulating cross arm adopts rectangle body structure and glass silk material to make from raw and other materials and structural improvement, satisfies the intensity of cross arm and bears the weight of gravity, solves the circuit and leads to the fact the line tripping phenomenon because of the overvoltage.
Description
Technical field
The utility model relates to power system lightning protection field, is specifically related to a kind of insulator crossarm.
Background technology
According to result of study, lightning stroke flashover depends on overvoltage value and line insulation level, and research showing the to be struck by lightning electric arc order of severity that causes reduces along with the reduction of the electric-force gradient along flashover path.So the insulating properties improving line insulation level and the shaft tower that increases electric power significantly can improve lightning stroke flashover.And at present both at home and abroad distribution network system major part electric force pole tower is horizontal irony cross-arm, wooden cross-arm, porcelain cross-arm.Wooden cross-arm insufficient strength, corrosion resistance is weak; Porcelain cross-arm insufficient strength, resist bending ability is inadequate; Irony cross-arm insulating properties are poor, easily get rusty.
Current the whole of 10KV power transmission and distribution line pole employing are iron cross arms, and by angle bar galvanizing process, then punched, galvanizing environmental pollution is very serious; In addition, traditional iron cross arm is employing 63 angle steel, installs heavy inconvenient, and does not have the effect of insulation, runs bring a lot of trouble to circuit.For adapting to the development of social spring tide, insulator crossarm will be breakthrough and the innovation of power product one leap property.
Utility model content
The purpose of this utility model is to overcome defect of the prior art, design a kind of insulator crossarm, insulator crossarm courageously breaks through from raw material, traditional iron cross arm is employing 63 angle steel, do not have the effect of insulation, we consider composite factor, make important improvement from material, meet intensity and the carrying gravity of cross-arm simultaneously.
For achieving the above object, the technical scheme that the utility model adopts is a kind of insulator crossarm, described cross-arm body is a hollow rectangular tube, and the two ends of this rectangular tube are open end, and in described rectangular tube, the junction of vertical plane is arc joint face between two.
Preferred version is wherein, described arc joint face comprises medial surface and lateral surface, and described medial surface is to the contour body bending near described lateral surface direction, and described lateral surface is the contour body to bending away from described medial surface direction.
Preferred version is wherein, the thickness of pipe wall of described rectangular tube is 6-10mm.
Preferred version is wherein, the thickness of pipe wall of described rectangular tube is 8mm.
Preferred version is wherein, described rectangular tube adopts glass wire quality to make.
Preferred version is wherein, four planes of described rectangular tube are specially the second plane composition of first plane on two the parallel long limits minor face parallel with two.
Preferred version is wherein, two described first planes are provided with some groups of corresponding manholes and/or strip through hole.
Preferred version is wherein, two described second planes are provided with some groups of corresponding manholes and/or strip through hole.
Advantage of the present utility model and beneficial effect are:
1, insulator crossarm structure of the present utility model is novel, employing rectangular tube constructs, its smooth surface, there is self-cleaning, avoid leaving moisture or dustiness etc. thereon and cause the surface insulated decline of cross-arm, also made certain breakthrough from energy-conservation aspect, after particularly installing insulator crossarm of the present utility model, circuit is no longer because overvoltage causes line tripping.
2, the medial surface of arc joint face and lateral surface are bandy contour body, in its mechanical performance of guarantee, can also improve shaft tower insulating properties, can reduce the electric discharge of most advanced and sophisticated place, increase lightning flash over path, improve line thunder protection effect.
3, the insulator crossarm adopting glass steel wire winding to make, mainly solves: circuit insulate completely with the earth, even if after insulator breakdown, circuit also can not ground connection, thus no longer cause line tripping.
4, its rectangular tube structure is installed light and handy convenient, and body is provided with the operation that the manhole of the correspondence of some groups and/or strip through hole optimize convenient installation further.
