Support and fastener for polarization resistors of on-load tap changer

Abstract

A support module () for polarization resistors of an on-load tap changer comprises:—a supporting region () for at least one polarization resistor; —a first joint region (); —a second joint region () which is compatible with the first joint region. A support frame () for polarization resistors of an on-load tap changer comprises:—two such support modules which are joined by virtue of the second joint region of the first support module bearing at least partially against the first joint region of the second support module. A fastening element () for polarization resistors () comprises:—two electrically conductive accommodating sections (), which each have an accommodating opening () for one of the ends () of a polarization resistor ();—an electrically conductive connecting section (), which connects the two accommodating sections () mechanically and electrically to one another;—a first piece (), which comprises the first accommodating section () and an adjoining first part of the connecting section (); —a second piece (), which comprises the second accommodating section () and an adjoining second part of the connecting section (); wherein:—the first and second parts are in the form of a plug-type connection.
