Claims

[Scope of utility model registration request]

A first contact is connected in series between a primary main winding and a primary tap winding of a high voltage transformer that are connected in series between high voltage lines, and the primary main winding and the first contact are connected in series. A second contact and a third contact are connected in parallel between the connection point and the tap terminal of the primary tap winding, and a current limiting resistor is connected in series to the third contact. In an uninterruptible tap switching device for a transformer, a common insulated operating shaft is provided for the first to third contacts, and the insulated operating shaft opens and closes the first to third contacts in a predetermined order. An uninterruptible tap switching device for a high voltage transformer, characterized in that it is provided with an opening/closing control member.
