摘要
An on-load tap changer (1) having at least two vacuum interrupters (3) is disclosed. The on-loader tap changer comprises a selector (7) for selecting a respective winding tap (n, n+1) of a tapped transformer (9), a load changeover switch (5) for changing over from the connected winding tap (n) to the respectively preselected winding tap (n+1), a rotatable drive shaft (11) which is mechanically coupled to the selector (7), and a gear mechanism (15) for operating a moving contact (17) of a respective vacuum interrupter (3). In each case one spindle (19) which can move in a direction of the axis (A) and is coupled to the moving contact (17) can be operated by means of the gear mechanism (15). The invention also relates to a drive for a load changeover switch having at least two vacuum interrupters.
