Abstract

PURPOSE:To protect a vacuum bulb housed in a change-over switch chamber partitioned by an insulating cylinder and a lower plate from intruding surge positively by arranging a disconnecting switch between the switch chamber and a tap selector in a three-phase one cylinder type phase adjusting load tap changer. CONSTITUTION:The three-phase one cylinder type phase adjusting vacuum bulb system on-load tap changer 42 is formed in such a manner that the tap selector 24, the disconnecting switch 28 and the change-over switch chamber 44 mainly constituted by the vacuum bulb 32 are disposed successively toward an upper section from a lower section. Thus, the disconnecting switch 28 is newly mounted additionally between the tap selector 24 and the change-over switch chamber 44, these are operated by means of a horizontal driving shaft 52 connected to an electromotive operating machine 46, a vertical driving shaft 62, a disc cam 68, etc. and connecting between the change-over switch chamber 44 and the tap selector 24 is cut by using the disconnecting switch 28 as necessary. Consequently, the disconnecting switch is incorporated into the tap selector, and the vacuum bulb is protected sufficiently from intruding surge.
