Abstract

PURPOSE: To rationally use change-over switches, by making connection among the three-phase change-over switches, which are produced by arranging the change-over switching portions of each phase at locations where the circumferential directions are divided into three portions, and each tap selector differ every tap changer when each load.
CONSTITUTION: When each connecting each-change over switch 1A, 1B, 1C, which are formed by arranging three-phase change-over switching portions U, V, W at locations where the circumferential directions are divided into three portions, and tap selectors 2A, 2B, 2C, said switches and selectors are connected in shapes that these are shifted every portion corresponding to one phase so that these each differ about tap changers I, II, III when each load. Consequently, idle phase can substantially be eliminated by successively using the change-over switches in a method that the change-over switch 1A is changed over to 1B and 1B to 1C at the points of the time when the life of the arc contacts of the change-over switching portions expires because there are each idle phase corresponding to two phase in the tap changes I, II, III when each load, thus rationally allowing to use change-over switches.
