Title:
POWER TAP CHANGER
Document Type and Number:
Japanese Patent JP3594419
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To safely, quickly and easily change the tap even in the active state by tightly mounting continuity nuts on bolts of tap changing terminals through an insulation plate until conductive members of the nuts strike against a conductive plate to bring the bolts of the tap changing terminals into a continuity with the conductive plate.
SOLUTION: A continuity nut 14 is inserted into a window hole 31 of any tap changing terminal e.g. 102 of an insulator cover 30 and its cap nut (conductive member) is tightly mounted on a bolt 16 of the terminal 102. The outside hexagonal part of an insulation grip 25 is held by spanner to rotate the nut 14 to tighten a conductive plate 13 until the lower end face of the cap part 15b of the nut strikes against the surface of the plate 13 to thereby safely bring the bold 16 into a continuity with the plate 13 through the cap nut. Thus a prim. coil circuit is formed between the tap of the prim. coil connected to a terminal 18 and variable terminal of the conductive plate 13.
