Abstract
The utility model discloses a connection structure of a no hard-point non-bonded high-speed contract line section insulator, comprising a contact wire, a connector, a diversion rod and an insulation rod, wherein the contact wire, the diversion rod and the insulation rod are all arranged on the bottom surface of the connector and are connected with the connector. The distance between the contact wire on the connector and a line of action of resultant force of the diversion rod and the insulation rod is shorter than 10mm. The insulation rod and the surface of the insulation rod are attached with a layer of material not easy to bond contaminants, in particular a layer of material not easy to bond pantograph pan carbon powder. As the section insulator has no hard points and does not bond the carbon powder, the section insulator can adapt to the needs of a high-speed electrified railway.
Description
Technical field
The utility model relates to the section insulator connection structure of using on a kind of electrification railway contact net.
Background technology
Section insulator is the vitals on the electrification railway contact net.Its effect is that contact system is carried out the power supply of branch section.The section insulator that uses on contact system at present has 2 shortcomings: the 1st, the hard spot of section insulator is too big, the bow situation often occurs beating, the time have pantograph to be smashed by section insulator report; The 2nd, the insulating bar of section insulator is polluted easily, reduces insulating capacity.In the friction process of pantograph pan and insulating bar, also can the bond carbon dust of pantograph pan of this insulating bar loses insulating capacity.The fault that section insulator is burnt happens occasionally.
The reason that hard spot appears in present section insulator is because contact wire connects in the bottom of joint, and the axis of insulating bar and diversion rod 15mm place above contact wire is connected with the joint of section insulator, make the not conllinear of making a concerted effort of the axle power of contact wire and insulating bar and diversion rod, form a very big couple, cause the contact wire at the section insulator two ends warpage that makes progress.
In order to improve the resistance to abrasion of the insulating bar in the section insulator, the insulating bar of section insulator adopts the method at glass-felt plastic (glass fiber laminate, below all be called glass-felt plastic) surface parcel high alumina ceramic sheath at present.Though high alumina ceramic is wear-resisting, the carbon dust on the pantograph pan that bonds easily loses insulating capacity.
As long as can find the surface of a kind of not only wear-resisting but also inadhesive material, just can solve the sticking carbon problem of insulating bar attached to insulating bar.
The utility model content
Technical problem to be solved in the utility model provides a kind ofly both can eliminate the section insulator hard spot, the non-caked high speed contact system of the no hard spot section insulator connection structure of the pantograph pan carbon dust of can avoiding again boning.
In order to solve the problems of the technologies described above, the non-caked high speed contact system of the no hard spot section insulator connection structure that the utility model provides, comprise contact wire, joint, diversion rod and insulating bar, contact wire all is connected with described joint in the bottom surface of described joint with insulating bar with described diversion rod.
The distance of the force action line of the described contact wire of described joint and described diversion rod, insulating bar is less than 10mm.
The surface attachment of described insulating bar and insulating bar one deck should not bond material of pollutants, particularly adhered to should not the bond material of pantograph pan carbon dust of one deck.
Adopt the non-caked high speed contact system of the no hard spot section insulator connection structure of technique scheme, all contact wire all is connected with joint in the bottom surface of joint with all rod members (diversion rod and insulating bar).Making that the distance between the force action line of the axis of contact wire and diversion rod, insulating bar is as far as possible little, is good to be no more than 3mm.Insulating bar is connected with joint from the bottom with flathead screw, contact wire, insulating bar and diversion rod are connected with the bottom of flathead screw from sectionalizing joint, make the axis of the axis of contact wire and diversion rod, insulating bar be positioned at same plane, the conllinear of making a concerted effort of the axle power of realization contact wire and insulating bar, diversion rod, just can eliminate the hard spot at section insulator two ends, reach the purpose of eliminating the segmentation hard spot.Next be in the surface attachment of insulating bar should not the bond material of pollutants of one deck.The carbon dust of the non-caked pantograph pan of this material can keep the insulating power of insulating bar.This is suitable for novel method of separating never sticking pantograph pan carbon dust is to take place to be pasted with polytetrafluoroethylene film or other material that should not adhere on the face of friction with pantograph pan.These materials not only can accomplish not adhere to the carbon dust of pantograph pan, and also should not boning, other reduces the pollutants of insulating power.
Because neither there is hard spot in this section insulator, non-caked again carbon dust can adapt to the needs of high-speed electric railway.
In sum, the utility model is a kind ofly both can eliminate the section insulator hard spot, the non-caked high speed contact system of the no hard spot section insulator connection structure of the pantograph pan carbon dust of can avoiding again boning.
