The rigid suspension double-wire catenary is mainly characterized in that two parallel copper contact wires (2) are embedded in an aluminum alloy busbar (1) on which three droop bodies (3) form two groups of dovetail notches, and two connecting plates (6) are arranged in two empty positions of the three droop bodies (3) to form an intermediate joint. The aluminum alloy busbar is good in extrusion process, large in transmission current, zero in break line fault, convenient to mount and reliable in connection. The rigid suspension double-wire catenary meets a power supply requirement of subway electric locomotives with the speed of 120km/h.
Description
Technical field
The utility model relates to a kind of rigidity suspension bifilar contact net, belongs to the equipment that power supply of urban orbit traffic is used.
Background technology
Before the utility model is made, in prior art, urban track traffic often adopts rigid suspended single line contact system to power to electric locomotive in tunnel.Because subway line electric current is up to 3000A, the temperature rise of rigid suspended single line contact system reaches 90 DEG C, and contact wire temperature reaches+and 135 DEG C, exceed international electrical engineering standard, dangerous, abrasion are large, keep strengthening electric conductor sectional area under prerequisite that 110mm is constant overcome its shortcoming in the urgent need to bus duct height.Though having the patent No. is the combined rigidity suspension bifilar contact net that 200420122393.5 rigidity suspension bifilar contact net device and the patent No. are 200720152966.2, because manufacturing process difficulty cannot be implemented greatly.And in the time that electric power locomotive speed will reach 120km/h, line current, up to 4000A, more will strengthen the sectional area of electric conductor.
Utility model content
The purpose of this utility model is to strengthen electric conductor sectional area under the prerequisite of bus duct height maintenance 110mm, reduces manufacturing process difficulty, and a kind of rigidity suspension bifilar contact net of high reliability is provided.
The main technical schemes that the utility model is dealt with problems is achieved in that and adopts the aluminum alloy bus duct 1 that forms two groups of dovetail groove orifices by three pendant 3 bottoms to embed two copper contact wires 2 arranged side by side, form center coupling by two connecting panels, 6 and 8 harness fasteners, be aided with suspension hook, insulating part, rigid-flexibility transition section etc. and form the traction power supply net to locomotive power supply.
Compared with the prior art the utility model has the following advantages:
1, electric conductor sectional area strengthens, and transmission current is large, temperature rise is low, without disconnection fault, wears away little.
2, the extrusion process of aluminum alloy bus duct is good, and dovetail furrow opening is even, reliable to copper contact wire clamping.
3, easy for installation, connect reliable.
4, Electric Locomotive is strengthened, speed can be brought up to 120km/h from 80km/h.
Brief description of the drawings
Fig. 1 is the cross-sectional configuration figure of agent structure of the present utility model.
Fig. 2 is the drawing in side sectional elevation of adjacent bus duct junction in the utility model.
Detailed description of the invention
With the embodiment in accompanying drawing, detailed description of the invention of the present utility model is described below.
It above in Fig. 1, is the horizontal plate of aluminum alloy bus duct 1, three pendants 3 dangle in its below, two pendant bottoms, left and right respectively have a claw to stretch to interior side-lower, a middle pendant bottom has two claws to stretch to outer side-lower, two dovetail furrow openings of four claw compositions, in order to clamp two copper contact wires 2.The original width of dovetail furrow opening is than also narrow 3mm left and right, the narrowest place of waist of copper contact wire 2, when copper contact wire 2 is embedded into after the dovetail groove orifice of bus duct 1, about 3mm is respectively opened in the bottom of left and right pendant, pendant is in elastic range, the neck of copper contact wire 2 is produced to side direction gripping power, this gripping power is far longer than the friction force and the vibratory force that are produced by motorcycle pantograph, and copper contact wire can not come off from the dovetail groove orifice of bus duct.In the case of the height of bus duct 1 and the bus duct height of rigid suspended single line contact system is consistent and pendant consistency of thickness, the sectional area of the bus duct 1 of rigidity suspension bifilar contact net has increased by 50%, reaches 3300mm
2, and copper contact wire in the situation that diameter is consistent because many sectional areas double, reach 300mm
2, total equivalent copper area change 65% left and right.Therefore this kind of rigidity suspension bifilar contact net electric current can be brought up to 4000A from 3000A, and temperature rise, lower than 45 DEG C, meets international electrical engineering standard.Therefore electric power locomotive speed can bring up to 120km/h from 80km/h.The below of three pendants 3 of bus duct 1 has the groove 4 of three 40 ° to regulate the opening and closing width of dovetail groove orifice for rule installation car.There is symmetrical projection 5 in two outsides, bottom of bus duct 1 for supporting rule installation car, and the supporting rollern of rule installation car rotates and drives rule installation car to vertically move at the upper surface of projection 5, and copper wiring 2 is embedded in the dovetail groove orifice of bus duct 1 continuously.
Fig. 2 is the drawing in side sectional elevation of adjacent bus duct junction.2 connecting panels 6 are placed at two neutral gear places at three pendants 3, and itself and 8 harness fasteners form center coupling.Be adjacent at the upper surface of bolt effect lower connecting plate 6 and the inside face of bus duct 3, the longitudinal half of connecting panel 6 is positioned at one end of a bus duct, second half is positioned at the abutting end of next bus duct, and connecting panel 6 plays electric current from a upper effect that bus duct passes to next bus duct.The parallel connection of two connecting panels 6 has improved the conduction reliability of center coupling, has reduced the temperature rise of junction.
After subway tunnel roof is installed crossbeam, hang up insulator, its lower end hangs over 12m or the long aluminum alloy bus duct order of 18m in the air through suspension hook, utilizes center coupling that adjacent bus duct is linked up.The leave the right or normal track distance of longitudinal centerline of the center of each insulator is gradual change, makes the line of centers of bus duct and track longitudinal centerline form a little angle, meets the requirement of " stagger ", makes motorcycle pantograph abrasion evenly.Finally utilize rule installation car copper contact wire to be embedded in the dovetail groove orifice of bus duct, composition power transmission network---a kind of rigidity suspension bifilar contact net, transmission DC1500V, 4000A electric current, make the pantograph of electric locomotive obtain electric current on two copper contact wires, electric locomotive is with the speed motion of 120km/h.
