    摘要： An on-load tap changer which comprises a rotary selector switch including a plurality of contacts which are divided according to phases into groups which are arranged in the axial direction of the tap changer, a rotary change-over switch including a plurality of contacts, and an intermittent drive mechanism connected between the selector switch and the change-over switch for intermittently transmitting the rotary motion of the selector switch to the change-over switch, the intermittent drive mechanism having an asymmetrical shape which provides a closest portion that is closest to the contacts of the change-over switch. The arrangement is such that the contacts of the change-over switch are divided into groups according to phases which are arranged in the circumferential direction of the change-over switch, the intermittent drive mechanism is at an electrical potential equal to that of the contacts of the selector switch closest to the intermittent drive mechanism, and the closest portion of the intermittent drive mechanism is positioned within a phase region within which the closest portion is positioned.

    摘要： A contact switching device has a driving link pivoted on its one end, a spring loaded slide slidably disposed within a longitudinal guide groove disposed on the other end portion of the driving link, a connecting link pivoted at one end on the slide and at the other end on an intermediate point of a driven link pivoted on its one end and having a movable contactor disposed on the other end portion of the driven link to separably engage two stationary contacts. Alternatively two connecting links having equal lengths may be pivoted at one end on the slide and at the other ends on respective driven links at points equidistant from the pivot on which the driven links are pivoted. The driven links have equal length and movable contactors for separably engaging pairs of stationary contacts. The contact of one pair is connected to one contact of the other pair.
