The insulation slideway and the flow guiding slideway are alternate with and connect with each other to form a diamond structure. The insulation slideway is formed by the coating layer which is arranged on the outer surface of a core rod. The connection wire clamps and the connection end of the flow guiding slideway extend, which is folded to an angle of alpha degrees. The end head of the connection end is acuminate. The upper surface of the end head and the connection wire clamps are on the same height. The lower surface is oblique upwards. The hanger of which the height is adjustable is arranged on the connection wire clamps on the both ends of the bridge. The utility model can considerably improve the quality and service life of the section insulator used for the contacting net in electric railway. The hanger of which the height is adjustable is arranged on the connection wire clamps on both ends of the bright insulator. The utility model can considerably improve the quality and service life of the section insulator used for the contacting net in electric railway.
Description
The utility model relates to a kind of contact nets in electrified railways sectioning.
China's contact nets in electrified railways section insulator is since the eighties, introduced the section insulator of Britain BB company, by the insulation slideway, the water conservancy diversion slideway, the bridge insulator, starting rod, joint wire clamp and connecting clamp are formed, insulation slideway and water conservancy diversion slideway are by the alternate diamond structure that is connected into connecting clamp of joint wire clamp, vertical two diagonal angles and the contact system cable of this structure are affixed, horizontal two diagonal angles are connected by the bridge insulator, this kind section insulator compact conformation, weight is lighter, be convenient to installation and maintenance, but its arc extinguishing rate is lower, anti-tracking performance is undesirable, install and use in be difficult to the plateau that guarantees the levelness of section insulator and using when, bend with electricity and be easy to produce electric arc when contacting even hit the bow phenomenon.
The purpose of this utility model is to overcome above-mentioned weak point, designs a kind of are-tight section insulator.
The technical solution of the utility model is: the are-tight section insulator of contact nets in electrified railways is by insulation slideway (1), water conservancy diversion slideway (2), bridge insulator (3), starting rod (4), joint wire clamp (5), connecting clamp (6) and dropper (7) are formed, insulation slideway (1) and water conservancy diversion slideway (2) are by the alternate diamond structure that is connected into connecting clamp (6) of joint wire clamp (5), vertical two diagonal angles and the contact system cable of this structure are affixed, horizontal two diagonal angles are connected by bridge insulator (3), insulation slideway (1) is provided with clad (9) by plug (8) outside face and constitutes, connecting clamp (6) extends with water conservancy diversion slideway (2) coupling end, itself and the water conservancy diversion slideway α angle of turning back, its termination is pointed, the termination upper surface is concordant with connecting clamp (6), lower surface is inclined upwardly, and bridge insulator two ends connecting clamps (6) top is provided with height-adjustable dropper (7).
The utility model can improve the quality and the life-span of contact nets in electrified railways section insulator greatly, the utility model insulation slideway is made up of plug and clad, plug mainly plays and holds lotus effect and also play insulating effect simultaneously, clad plays insulation, anti-electric arc, wear-resisting, improves effects such as anti-tracking performance.The connecting clamp elongated end constitutes the effect of horn gap extinguishing arc, improves the arc extinguishing rate, and the joint wire clamp adopts the silicon brass precision casting process to make, and the albronze wire clamp all commonly used at aspects such as resistance to abrasion, intensity, frictions is good, and the reliability of working under load is good.The raising of wire clamp quality will make the regulation that can reach the standard TB1848.87 of the Ministry of Railways with the sliding load of contact wire joint fully.Above the connecting clamp of bridge insulator two ends, be provided with dropper, cooperate under the tension force situation of section insulator two end cables, install and use in can guarantee the levelness of section insulator and the plateau when using, thereby when contacting with the electricity bow unlikely generation electric arc with hit the bow phenomenon.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model front view.
Fig. 2 is the utility model birds-eye view.
Fig. 3 is insulation slideway schematic cross-section.
The are-tight section insulator of contact nets in electrified railways is by insulation slideway 1; water conservancy diversion slideway 2; bridge insulator 3; starting rod 4; joint wire clamp 5; connecting clamp 6 and dropper 7 are formed; insulation slideway 1 and water conservancy diversion slideway 2 are by joint wire clamp 5 and the connecting clamp 6 alternate diamond structures that are connected into; vertical two diagonal angles and the contact system cable of this structure are affixed; horizontal two diagonal angles are connected by bridge insulator 3; water conservancy diversion slideway 2 tops are provided with starting rod 4; extend formation starting rod 4 with insulation slideway 1 bonded assembly connecting clamp 6 one ends; four starting rods 4 constitute the parallelogram plane above shackle; protection insulation component during lightning surge; prevent to burn out; play the arc extinguishing effect, dwindle the accident scope.Insulation slideway 1 is provided with clad 9 by plug 8 outside faces and constitutes, plug 8 mainly plays and holds the lotus effect while and also play insulating effect, with alkide resin-epoxy resin is matrix, is reinforcing material with the high-strength glass fibre of handling through chemical treatments, and glass fibre as prescribed direction is arranged during the preparation plug.Clad 9 is to adopt the composite material of polyester-fluoropolymer and short glass fiber to make, has good resistance to abrasion to reach, arc resistance, anti-tracking and good power frequency wet withstand voltage performance, play insulation, anti-electric arc, wear-resisting, improve effect such as anti-tracking performance.Connecting clamp 6 is connected an end and extends with water conservancy diversion slideway 2, itself and water conservancy diversion slideway knuckle α are 15 °～30 °, its termination is pointed, the termination upper surface is concordant with connecting clamp (6), and lower surface is inclined upwardly, and joint wire clamp 5 and connecting clamp 6 are made by silicon brass, connecting clamp 6 tops, bridge insulator two ends are provided with Connection Block 10, dropper 7 bottoms are fixed on the Connection Block 10, and dropper 7 by being threaded, can be regulated dropper 7 height by adjusting screw thread by two sections swing pipes.Dropper 7 tops are fixed on the contact system catenary.When not having electric locomotive to pass through, section insulator with the electricity of two sections by rhombus opposite side insulation slideway 1, bridge insulator 3 is isolated, when electric locomotive passes through, locomotive electricity bow passes through joint wire clamp 5 and insulation slideway 1 by cable conductor, water conservancy diversion slideway 2 connects, when moving to the section insulator centre, the electricity bow contacts with the copper connecting clamp 6 of bridge insulator 3 two ends respectively, make electric locomotive accept two section power supplies simultaneously, continue operation, the other both sides that enter rhombus then promptly the electricity bow again with insulation slideway 1,2 contacts of water conservancy diversion slideway, the zone of sailing another section electricity by connecting clamp 6 into.Contact, break away from moment at electric locomotive electricity bow and bridge insulator 3 two end connecting clamps 6 and be easy to produce arc spark, at this moment, starting rod 4 and connecting clamp 6 extension discharging sharp-angles have discharge, extinguishing arc effect, avoid electric arc that insulating part is burnt out.Dropper 7 has guaranteed that the levelness of section insulator makes the electricity bow steadily contact with bridge insulator 3 two ends, thus the danger that can avoid the generation of electric arc and hit bow.
