Description
Technical field
The present invention relates to a kind of railway high voltage traction transformer, belong to the manufacturing technology field of transformer.
Background technology
China railways traction circuit is 27.5kV to the voltage of track, is generally 110kV or 220kV for the supply voltage of the three-phase electrical power system of traction line powering.At present, the employed traction transformer of China railways traction circuit mostly is the 110kV electric pressure greatly, and the line loss of 110kV level traction transformer power transformation operation is very big, and operating cost is also very high.Along with the continuous development of China's electric railway, the 220kV electric power system has more stability and reliability, and single phase power supply more meets railway electricity consumption characteristics, and protection is simple, input is little, can effectively reduce railway operating expense.Therefore, the single-phase railway traction transformer of 220kV level arises at the historic moment.But because transformer will be subjected to the seismic force effects that various impulsive contact forces (swing of the jolting of the start-stop of train, highway transportation, water route transportation etc.) and transformer in service may be subjected to by manufactory in the transportation of erecting bed, casing and device body are easy to generate unallowed displacement or damage, winding and iron core are easy to generate loosening, thereby influence dielectric strength, overload and the anti-short circuit capability of transformer.
Summary of the invention
The object of the present invention is to provide a kind of reasonable in designly, can satisfy the instructions for use of rail traction circuit, do not need to carry out the railway high voltage traction transformer of pendant-core examination during on-the-spot the installation.
The present invention is a railway high voltage traction transformer, comprise with the casing at the bottom of two casees, place the device body that constitutes by winding and iron core in the casing, the fuel tank that constitutes by last fuel-economizing case and lower oil tank, the two ends that it is characterized in that winding are provided with insulating end ring, are provided with cardboard cylinder in the winding; Iron core is by curb girder, and last drawstring fills up pin, arm-tie, and high pressure upper clamping piece and low pressure upper clamping piece form a firm integral body; The iron core bottom places in the lower oil tank, with the wedging all around of wedging wooden unit; The end of winding also is provided with pressing plate, cooperates by the arm-tie on nail of the pressure on the pressing plate and the iron core to axially fasten; Last fuel-economizing case is provided with four positioners; The device body that is made of winding and iron core places on two casees baseplanes.
The outside, bottom of described iron core also can be provided with the layback band, with further tension iron core.
Also can be provided with stretching screw between at the bottom of described pressing plate and two casees, the axial pressing force of the device body that constitutes by winding and iron core with further reinforcement.
Described device can be 2-4 and is set up in parallel in casing.
The present invention compared with prior art has following outstanding advantage and good effect:
1, the used cardboard of the insulating end ring at winding two ends hot forming after overstockedization processing is provided with cardboard cylinder in winding inner diameter, and has interior outer stay to guarantee the winding mechanical strength, fixes with the colligation of contraction bands bowknot lifting one's head the position, cannot not cause looseningly.
2, iron core has formed a firm integral body by curb girder, drawstring, pad pin, arm-tie, folder and iron core, sets up layback band tension iron core again in the mandrel lower outside, makes whole iron core column consolidation more.
3, adopt the mode of closely cooperating between winding and insulating part, insulating part and winding, winding and iron core, made winding, insulating part, iron core form a fastening integral body, guaranteed not produce each other horizontal displacement, loosening.At winding overhang certain thickness high strength pressing plate is set, cooperates with spring pressed stud, iron core arm-tie to axially fasten, the axial pressing force of pressing nail has increased by four Φ, 24 axial stretching screws much larger than the axial force of calculating again in order to strengthen axial pressing force; Device on one's body, the lower yoke cushion block all passes through the hot-pressing processing postforming, and is corresponding with cushion block on the winding, stay position, guarantees each winding, cushion block, the equilibrium of insulating part pressurized, implements, no unsettled.
4, iron core is embedded in the lower oil tank, with the wedging all around of wedging wooden unit, can make iron core be in stable state fully.Last fuel-economizing case has four positioners, can make four jiaos of location of iron core and last fuel-economizing case, and it all can not be moved in any direction, and device body then seat is placed on two casees baseplanes of flute profile fuel tank, because supporting surface is big at the bottom of two the casees, helps the stable of device body.
The present invention passes through the series of optimum design between above-mentioned each parts and the parts thereof, make the overall structure of railway high voltage traction transformer more become reasonable, closely cooperate between each parts, can guarantee that transformer is in transportation, do not produce displacement or damage between casing and the device body, need not carry out pendant-core examination after transporting the scene to, can effectively improve dielectric strength, overload and the anti-short circuit capability of railway high voltage traction transformer, satisfy the instructions for use of rail traction circuit.
