Abstract
The utility model discloses a system for an internal combustion locomotive. The system comprises a coil circuit LLC, a coil circuit LC and a relay 6ZJ, wherein a tachometer generator is put into work when the coil circuit LLC is electrified; an exciter is put into work when the coil circuit LC is electrified; two pairs of normally-closed contacts of the relay 6ZJ are respectively connected into the coil circuit LLC and the coil circuit LC and are respectively short-circuited through two short-circuit wires. According to the technical scheme, the two pairs of normally-closed contacts of the relay 6ZJ are short-circuited, so that the potential safety hazard problem that the unloading fault of the locomotive is not displayed because of poor contact between the normally-closed contacts of the relay 6ZJ can be thoroughly eliminated.
Description
Technical field
The utility model relates to diesel locomotive field, particularly, relates to a kind of system for diesel locomotive.
Background technology
DF12 type locomotive is the heavy shunting locomotive of large power, electrically transmission that Ziyang locomotive works produce, be a kind ofly doublely shunt, the high-mobility, multipurpose, wheeled vehicle locomotive of little running and main line shipping.
Fig. 1 is the structural representation of a system in this diesel locomotive.As shown in Figure 1, this system only has 1,2HKF reverser, without mode switch.So this type locomotive only have traction forward, draw function backward, without traction, braking translation function, without from load, rheostatic brake function.When driver controller handle is put system position, contact SK-4 closure, relay 6ZJ obtains electric, and two pairs of normally closed interlocks in its switch-on coil circuit LLC, LC disconnect, and have cut off respectively coil circuit LLC, LC, make locomotive unloading.
But the design of said system and diesel locomotive all require coil circuit LLC(tachogenerator to devote oneself to work under traction working condition or under damped condition) and coil circuit LC(exciting dynamo devote oneself to work) requirement that must energized action is contrary.In addition, two couples of normally closed interlock (4012-4013; 4009-4010) access respectively in coil circuit LLC, LC, because of loading station coal dust more, shunter work under bad environment, thinner coal dust easily enters contact inside, pad contact, cause contact bad (contact virtual connection), make locomotive unloading, bring serious potential safety hazard to the normal operation of locomotive, also can have influence on normal shunting service order simultaneously.
Therefore, in existing system, relay 6ZJ design is unreasonable, is in operation and often occurs that the locomotive causing because of the virtual connection of 6ZJ contact, without stream fault with no pressure, very easily causes locomotive failure operation to occur slowly.
Utility model content
The purpose of this utility model is to provide a kind of system for diesel locomotive, and it can be revised relay 6ZJ and design irrational defect, avoids locomotive failure and operation to occur slowly.
To achieve these goals, the utility model provides a kind of system for diesel locomotive, and this system comprises: coil circuit LLC, and this coil circuit LLC obtains when electric, and tachogenerator is devoted oneself to work; Coil circuit LC, this coil circuit LC obtains when electric, and exciting dynamo is devoted oneself to work; And relay 6ZJ, two pairs of normally closed interlocks of this relay 6ZJ access respectively described LLC coil circuit and LC coil circuit, and described two pairs of normally closed interlocks are respectively by two shorting stubs and by short circuit.
By technique scheme, short circuit two pairs of normally closed interlocks of relay 6ZJ, can thoroughly eliminate the locomotive that causes because of the bad contact of relay 6ZJ normally closed interlock without the security hidden trouble that shows unloading fault.
Other feature and advantage of the present utility model are described in detail the detailed description of the invention part subsequently.
Brief description of the drawings
Accompanying drawing is to be used to provide further understanding of the present utility model, and forms a part for specification sheets, is used from explanation the utility model, but does not form restriction of the present utility model with detailed description of the invention one below.In the accompanying drawings:
Fig. 1 is the structural representation of a system in diesel locomotive; And
The structural representation of the system for diesel locomotive that Fig. 2 provides for the utility model.
Description of reference numerals
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.Should be understood that, detailed description of the invention described herein only, for description and interpretation the utility model, is not limited to the utility model.
The structural representation of the system for diesel locomotive that Fig. 2 provides for the utility model.As shown in Figure 2, the utility model provides a kind of system for diesel locomotive, and this system comprises: coil circuit LLC, and this coil circuit LLC obtains when electric, and tachogenerator is devoted oneself to work; Coil circuit LC, this coil circuit LC obtains when electric, and exciting dynamo is devoted oneself to work; And relay 6ZJ, two pairs of normally closed interlocks of this relay 6ZJ access respectively described LLC coil circuit and LC coil circuit, and described two pairs of normally closed interlocks are respectively by shorting stub 10 and shorting stub 20 and by short circuit.
By two couples of normally closed interlock (4012-4013 of short circuit relay 6ZJ; 4009-4010), can thoroughly eliminate because of pollution caused by coal dust, contact dust stratification too much, contact reduces, the aging rear bad contact of contact causes locomotive is without showing unloading fault.In addition, by relay 6ZJ is retained in coil circuit, can be this type locomotive and install rheostatic brake function later additional and do the design of a reserved property.
After above-mentioned technological change, to relay 6ZJ misoperation or the bad LLC causing of contact, LC coil circuit dead electricity discharge, locomotive unloading problem can be solved.
Scheme of the present utility model is applicable to DF12 type locomotive, also applicable to the diesel-electric locomotive of other model such as DF4B, DF4C.Certainly be not limited to this, any locomotive that adopts the utility model scheme is all applicatory.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition each the concrete technical characterictic described in above-mentioned detailed description of the invention, in reconcilable situation, can combine by any suitable mode.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible array modes.
In addition, also can carry out combination in any between various embodiment of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
