CYLINDRICAL LOAD DIVERTER SWITCH FOR TAP-CHANGERS OF TAPPED TRANSFORMERS

摘要

The load switching arrangement for stepwise switching of stepped transformers has a cylindrical oil vessel and a with drawable load switching insert. On the housing there are fixed main and auxiliary contacts while for the feed of constant current there are prearranged constant current contacts. The fixed constant current contacts(20) sit directly on the inner wall of the cylindrical oil vessel(1). In the cylindrical oil vessel there can be inserted a cylindrical load switcher(2). This can have a drive part with a stepped swithching head(3). The housing for the load switcher(2) can be made up of three cylindrical shells(6,7).
