Abstract

The utility model discloses a main transformer of an electric locomotive for passenger and freight. Secondary winding coils comprise a first traction coil a1*1, a second traction coil a2*2, a third traction coil a3*3, a fourth traction coil a4*4, a fifth traction coil a5*5, a sixth traction coil a6*6, a first auxiliary coil a7*7, a second auxiliary coil a8*8, a first power supply coil a9*9 and a second power supply coil a10*10 all do not connect with one another. The main transformer provided by the utility model has the advantages that the layout is reasonable and the structure is compact; the power supply coils can be additionally arranged in the limited space of the present main transformer of the electric locomotive for passenger and freight, and windings adopt layered structures while the secondary winding coils are not connected with one another, solving the decoupling problem among the windings; the impedance voltage of the traction coils in various work (freight and passenger) combinations is constant, meeting the requirement of the locomotive for passenger and freight; and no another electric locomotive is needed, so that the transport cost can be reduced.

Description

The passenger-cargo dual-purpose electric locomotive main transformer

Technical field:

The utility model relates to a kind of locomotive main transformer, especially a kind of passenger-cargo dual-purpose electric locomotive main transformer that can satisfy passenger-cargo two kinds of electric locomotive demands simultaneously, reduce cost of transportation.

Background technology:

At present, the electric locomotive that is moving has passenger traffic, freight locomotive, and when transportation demands such as spring transportation were big, freight locomotive was wherein taken on the traction of Passenger Electric Locomotive.Because the main transformer of existing freight locomotive has only hauling-eye and ancillary coil not to have the locomotive power supply coil, all need to increase a joint power supply car when drawing is the compartment power supply of Passenger Electric Locomotive at every turn, has strengthened cost of transportation.

Summary of the invention:

The utility model is in order to solve the above-mentioned technical problem of existing in prior technology, a kind of passenger-cargo dual-purpose electric locomotive main transformer that can satisfy passenger-cargo two kinds of electric locomotive demands simultaneously, reduce cost of transportation to be provided.

Technical solution of the present utility model is: a kind of passenger-cargo dual-purpose electric locomotive main transformer, winding construction adopts laminar, primary winding coil is high-tension coil A-X, it is characterized in that: the secondary winding coil has the first hauling-eye a1x1, the second hauling-eye a2x2, the 3rd hauling-eye a3x3, the 4th hauling-eye a4x4, the 5th hauling-eye a5x5, the 6th hauling-eye a6x6, the first ancillary coil a7x7, the second ancillary coil a8x8, the first power supply coil a9x9 and the second power supply coil a10x10, does not connect mutually between the secondary winding coil.

The utility model is rationally distributed, compact conformation, can in having the limited space of freight locomotive main transformer now, increase the power supply coil, the structure of each winding adopts laminar and secondary winding not to connect mutually, has solved the decoupling problem between each winding, can make hauling-eye under various work (shipping, passenger traffic) combination, impedance voltage is invariable, to satisfy the demand of visitor, two kinds of locomotives of goods, need not to add in addition a power supply car, can reduce cost of transportation.

Description of drawings:

Fig. 1 is the elementary diagram of the utility model embodiment.

Embodiment:

Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: the same with existing freight locomotive main transformer, the integrated transformer of employing underslung mounting means, winding construction adopts laminar, primary winding coil is high-tension coil A-X, adopt the Nomex paper covered wire, have the thermal endurance class height, the characteristics that mechanical strength is big.Different is that the secondary winding coil has the first hauling-eye a1x1, the second hauling-eye a2x2, the 3rd hauling-eye a3x3, the 4th hauling-eye a4x4, the 5th hauling-eye a5x5, the 6th hauling-eye a6x6, the first ancillary coil a7x7, the second ancillary coil a8x8, the first power supply coil a9x9 and the second power supply coil a10x10 with prior art, does not connect mutually between the secondary winding coil.

When electric locomotive used as lorry, the power supply coil windings was not worked, all the other coil windings work; When electric locomotive drew use as passenger vehicle, all coils winding was all worked.

Claims

1. passenger-cargo dual-purpose electric locomotive main transformer, winding construction adopts laminar, primary winding coil is high-tension coil A-X, it is characterized in that: the secondary winding coil has the first hauling-eye a1x1, the second hauling-eye a2x2, the 3rd hauling-eye a3x3, the 4th hauling-eye a4x4, the 5th hauling-eye a5x5, the 6th hauling-eye a6x6, the first ancillary coil a7x7, the second ancillary coil a8x8, the first power supply coil a9x9 and the second power supply coil a10x10, does not connect mutually between the secondary winding coil.
