PURPOSE:To enhance the strength of mechanical force of winding against short circuit and strengthen a supporting structure of winding by dividing a winding into upper and lower two portions, providing insulating stud in such split space and by tightening both ends of stud with bolts. CONSTITUTION:At least one of the low voltage winding 4 and high voltage winding is divided into upper and lower portions. A plurality of insulation studs 22 are arranged in the circumferential direction in the split space thereof. A basic insulating cylinder 20 and a high voltage shield 21 arranged at both ends of winding 5 are tightened and fixed by tightening both ends of stud 22 with bolts. Thereby, strength for mechanical force of winding against short circuit can be improved and supporting structure of winding can be stabilized. |
