Abstract

A vacuum interrupter arrangement may be used in a tap changer. The vacuum interrupter arrangement has a vacuum interrupter; a metal shield configured to shield against external magnetic fields, the metal shield having a hollow cylindrical design and being arranged around at least a part of a cylindrical outer surface of the vacuum interrupter; and a holder, which is arranged on the outside of the metal shield and the vacuum interrupter, and which surrounds the metal shield and the vacuum interrupter at least partially coaxially. The holder has a plurality of holding elements which hold the metal shield in position relative to the vacuum interrupter.
