RU181967U1 - Throttle jumper - Google Patents

Abstract

The throttle jumper is designed to pass the reverse traction current of electric locomotives, as well as to connect choke transformers and can be used in rail circuits to pass the reverse traction current from electric locomotives. The jumper contains a stranded steel-copper wire. A plug is welded to one end of the wire, the other end is welded to the bus. A section of wire passing under the rail is equipped with an insulator. The insulator contains a layer of reinforcing material and a protective shell based on rubber. The utility model is supplemented by a bracket that allows the throttle jumper to be mounted to the rail sole.

Description

The utility model relates to the field of signaling, centralization and blocking in railway transport and can be used in rail circuits for passing reverse traction current of electric locomotives, as well as for connecting choke transformers.

Known throttle jumpers containing wire, plug and bus (V.I. Soroko, V.A. Milyukov. Equipment for railway automation and telemechanics: in 2 books. Book 1, 3rd edition. - M .: NPF Planeta ", 2000, S. 784-787, Fig. 299-301).

The disadvantage of these jumpers is that sections of the jumpers passing under the rails are destroyed under the influence of elevated temperatures and vibration.

Another disadvantage is the uncontrolled contact of the jumpers with the rails.

The closest in technical essence and the achieved effect to the proposed utility model is the "Throttle jumper" containing a stranded steel-copper wire with a plug welded to one end, the other end of the wire welded to the bus, and the section of wire passing under the rail is equipped with an insulator. The insulator contains a layer of reinforcing material and a protective shell based on rubber (RF patent No. 160194, B61L 1/02, priority July 27, 2015, published March 10, 2016 Bull. No. 7).

The disadvantage of this utility model adopted as a prototype is that the sections of the jumpers passing under the rails are destroyed by vibration.

The technical result of this utility model is the development of the design of the throttle jumper, which will provide the possibility of its fastening on the sole of the rail and, as a result, eliminate the possibility of damage to the wire and insulator due to vibration and increase its service life.

The technical result is achieved by the fact that a throttle jumper containing a wire, a plug inserted into the hole of the rail is welded to one end and the other end is welded to the rail, and the wire section passing under the rail is equipped with an insulator consisting of a layer of reinforcing material covered by a protective a rubber-based sheath, and the insulator is fixed to the wire using clamps, is additionally equipped with a bracket fixed to the insulator with clamps and allowing the throttle jumper to be fixed to the soles e rail.

A utility model is illustrated in FIG. one.

The jumper contains a stranded wire 1, to one end of which a plug 2 is welded, inserted into the hole of the rail. The other end of the wire is welded to a bus 3 connected to a choke transformer (not shown). A section of wire passing under the rail is protected by an insulator consisting of reinforcing material 4 and a protective sheath based on rubber 5. This layer of reinforcing material protects the jumper from the influence of traction current and increases its heat resistance. There may be several such layers. To protect against damage, the layer of reinforcing material 4 is covered by a protective shell based on rubber 5, which is attached using clamps 6. The protective shell increases the vibration resistance of the jumper. Thus, the layer of reinforcing material 4 and the protective sheath 5, forming an insulator, exclude the possibility of uncontrolled contact of the jumper with the rail. If necessary, a similar insulator is installed in the area of the wire passing under the second rail. The bracket 7 is made of sheet steel and contains four holes for fastening to the insulator using clamps 6 and allows you to fix the throttle jumper on the bottom of the rail.

The design of the proposed utility model provides an increase in the service life of the device and eliminates the possibility of damage to the throttle jumper due to vibration.
