Abstract

PURPOSE:To enable to simplify the remodeling work on a no-voltage tap changing system as well as to cut duwn the expenses for remodeling by a method wherein an adjustment transformer is connected to a three-phase hight-tension winding, and the tap winding of said adjustment transformer and the tap changing device are connected in series to the high tension winding. CONSTITUTION:The tap winding 5 of the adjustment transformer and an on-load tap changing device 6 are connected in series to the high-tension winding of each phase, the exciting winding 7 of the adjustment transformer is connected in parallel in between U and Y, and W and Z respectively, the tap winding 5 and the exciting winding 7 are wound around on the same core and the constitution of the adjustment transformer is completed. Thus, as the remodeling of the transformer of no- voltage tap changing system can be accomplished by merely performing remodeling on a high-tension lead and by attaching the adjustment transformer and the on-load tap changing device, the remodeling work can be done in a short time at a small expenses.
