The utility model is described in further detail for mode.
Please refer to Fig.1 and Fig. 2, Fig. 1 be oil pipe short-circuit device provided by the utility model a kind of specific embodiment
Structure diagram；Fig. 2 is a kind of knot of specific embodiment center tap of oil pipe short-circuit device provided by the utility model
Structure schematic diagram.
Specific embodiment of the present invention provides a kind of oil pipe short-circuit device of traction transformer of locomotive, is connect including two
First 1 and a hose 2, two connectors 1 are respectively communicated with transformer flowline and oil return pipe, i.e. two connectors 1 connect transformer
One end is head end, and the other end is end, and the head end of two connectors 1 is both provided with connector, is detachably connected transformer flowline
Or oil return tube opening, the both ends of hose 2 connect the end of two connectors 1 respectively, and pass through hose 2 and two connectors 1 are connected.
Transformer flowline and oil return pipe are respectively communicated with by two connectors 1, and passes through hose 2 and connects two connectors 1, by
In hose 2 can random variation, can adapt to the different distance of various model transformer flowlines and oil return pipe, and pass through connector
It is detachably connected, it is simple and light, it is quick for installation, it does not need to remove transformer section oil inlet pipe or oil return pipe, improves work effect
Rate.
Wherein connector can have diversified forms, can be the ring flange 11 for being set to 1 head end of connector, stable connection,
It is easily installed dismounting.Specifically, according to the structure of transformer flowline and oil return pipe, the ring flange 11 for connecting flowline is rectangular
Flange, the quadrangle of square flange are provided with connecting hole, and the ring flange 11 for connecting oil return pipe is hexagon flange, hexagon flange
Quadrangle is provided with connecting hole.Also can according to circumstances adjust flange has shape, such as be arranged to circular flange or using other
Connection mode, such as coordinated using the seal sleeve of suit with nut is tightened, it is within the protection scope of the utility model.
In the oil pipe short-circuit device provided in specific embodiment of the present invention, in order to be stably connected with hose 2, it can connect
First 1 end sets connecting tube 12, and for the end sleeve of hose 2 loaded on connecting tube 12 and tight connecting tube 12, connector 1 passes through connection
Hose 2 is connected in pipe 12.That is the both ends of connecting tube 12 are both provided with opening, and simultaneously connector 1 is connected in 1 end of one end open jointing,
Another end opening is set in by hose 2 in hose 2, hose 2 is connected, and the outer diameter of connecting tube 12 is slightly larger than the internal diameter of hose 2, but
Due to hose 2 have certain elasticity, be hose 2 can tight connecting tube 12, prevent from revealing.
Hose 2 comes off in order to prevent simultaneously, multiple tracks can be set to prevent being disengaged from the groove in 12 periphery of connecting tube, and multiple tracks prevents being disengaged from the groove along even
12 extending direction of take over is set gradually, and with guiding surface, and when installing hose 2, guiding surface forward direction enters hose 2, when having
During abjection trend, guiding surface meeting reverse movement makes connecting tube 12 be difficult to, improves stabilization of equipment performance.For the ease of installing,
Can 12 end of connecting tube, i.e. one end far from connector 1 be provided with hemisphere guide head, i.e. the end of connecting tube 12 has streamline

In the oil pipe short-circuit device provided in specific embodiment of the present invention, 1 middle part of connector, which is provided with, to be bent in an arc shape,
Make the opening direction of 1 head end of connector perpendicular to the opening direction of 1 end of connector, i.e., connector 1 is a bend pipe, and bending angle is
90 degree, bending angle is also can adjust, adapts to different transformers.
In installation process, according to the different location that different model transformer flowline and oil return pipe are set, two connectors 1
Mounting means can also adjust accordingly, if flowline and oil return pipe are horizontally disposed with and are open and be located in same perpendicular, then
The head end opening of two connectors 1 is located at towards identical and opening in same perpendicular, and the distal opening of two connectors 1 is opposite to be set
Put, and tilt down, i.e., after connection flexible pipe 2, whole device is in alphabetical V-type, ensures that fluid flowing is smooth, according to flowline and
The difference of oil return pipe distance, the angle of V-type change therewith, are critical distance after hose 2 stretches, can pass through replacement at this time
The longer hose 2 of length realizes follow-up work.
It, can also be on the top at 1 middle part of connector on the basis of the oil pipe short-circuit device provided in above-mentioned each specific embodiment
Gas outlet is provided with, the drain tap 13 for controlling with extraneous conducting state is provided at gas outlet.It connects and stores up in transformer
In the case of Oil Tank, after opening the valve on flowline or oil return pipe, drain tap 13 is beaten, connector 1 is made to be connected with extraneous, in weight
Under the action of power, fluid is from the hose 2 that oil conservater flows to oil pipe short-circuit device, and gas therein is from gas outlet via air bleeding valve
Door 13 is emitted into the external world, prevents gas during oil cycle from entering transformer, improves stability, after the completion of exhaust, closes drain tap
13, completely cut off extraneous and connector 1, continue oily cycle.Gas outlet is set to the peak of connector 1, row during convenient for oiling
Gas works.
In order to observe exhaust gas conditions, transparent hose can be connected in 13 exit of drain tap, when lasting in transparent hose
After the pure oil for flowing out bubble-free, that is, represent that exhaust is completed, and can close drain tap 13.
In addition to above-mentioned oil pipe short-circuit device, specific embodiment of the present utility model also provides a kind of short including above-mentioned oil pipe
The traction transformer of locomotive of connection device, refer to the prior art for the structure of other each sections of the traction transformer of locomotive, herein not
It repeats again.
Traction transformer of locomotive provided by the utility model and its oil pipe short-circuit device are described in detail above.
Specific case used herein is expounded the principle and embodiment of the utility model, and the explanation of above example is only
It is the method and its core concept for being used to help understand the utility model.It should be pointed out that the ordinary skill for the art
For personnel, under the premise of the utility model principle is not departed from, can also to the utility model, some improvement and modification can also be carried out,
These improvement and modification are also fallen into the protection domain of the utility model claims.
