Background technology
The single-phase traction transformer of AT power supply usefulness is because the impedance requirement is very little, and the single winding construction of existing single-phase traction transformer can't satisfy following low-impedance requirement:
For single-phase Ii wiring, (3Z
21+ Z
31-Z
23-1)/4＜(0.45/4) Ω (error is less than ± 10%).
Wherein:
Z
21Be the impedance of seeing from secondary side (traction winding) after the primary side short circuit.
Z
31Be the impedance of seeing from three sides (just presenting winding) after the primary side short circuit.
Z
23-1Be the impedance of seeing from two ends, two, three side windings in series loops after the primary side short circuit.
