Summary of the invention
The purpose of this invention is to provide a kind of reasonable in designly, have reliable dielectric strength, the machine body structure of the single-phase traction transformer of overload and anti-short circuit capability.
The present invention is the machine body structure of single-phase traction transformer, comprise core limb, series connection also places two high-tension coil and low-voltage coils on the core limb respectively, it is characterized in that low-voltage coil is radial splitted construction, form by two or four coils, be provided with paper web oil clearance insulation system between two or four coils; The high-tension coil head end is for being entangled with the formula winding structure, other line segment is the continous way winding structure, be provided with electrostatic ring between high-tension coil head end and high-tension coil end and the end circle, the terminal interlayer with core insulation of high-tension coil head end and high-tension coil is arranged with the twice square ring.
The top of described high-tension coil and low-voltage coil is fixed by the pressing plate of band spring pressed stud.
Can be located by location-plate between four jiaos of described core limb and last fuel-economizing case, the bottom is located by locating pin.
The present invention compared with prior art has following outstanding advantage and good effect:
1, paper web oil clearance insulation system is set on low-voltage coil, electrostatic ring and square ring are set on the high-tension coil, good insulation preformance, improved anti-short circuit capability, promptly apply rated voltage, under the condition of secondary side dead short circuit, under the effect of short circuit current at primary side, in 2 seconds and 3 seconds in secondary pulse, can not cause any heat and mechanical damage;
2, adopt " four jiaos of location " structure in the transformer body, location-plate everywhere makes core limb and four jiaos of location of last fuel-economizing case, it all can not be moved in any direction, and the locating pin location is adopted in the bottom, guarantees needn't carry out pendant-core examination after transformer transports the scene to this;
3, high-tension coil and low-voltage coil adopt the Rational structure that spring pressed stud evenly distributes and compresses, that during assembling the winding height on high-tension coil and the low-voltage coil is all adjusted is in full accord, make each winding stressed evenly, and the suffered electric power of winding is cushioned to some extent and winding is resetted immediately, so its anti-frequent short circuit and running overload ability are strong.
The present invention is reasonable in design, has reliable dielectric strength, and overload and anti-short circuit capability are used for the single-phase railway traction transformer of AT supply power mode,, can satisfy the demand of present electric railway.
