Disconnector switch for voltage transformer

摘要

A disconnector unit for a medium voltage application, with a conductive pen inside a housing. The conductive pen is moveable between an operational position in which an electrical contact is provided between a first terminal and a second terminal positioned inside the housing, and an off position in which no electrical contact is present between the first terminal and the second terminal. The conductive pen includes a first actuating part inside the housing, optionally, in the form of a magnet. The disconnector unit further includes a second actuating part positioned outside the housing, wherein the first actuating part and second actuating part form a non-mechanical link.

1. A disconnector unit for a medium voltage application, the disconnector unit comprising:
a conductive pen disposed inside a housing; and a second actuating art having a second magnet disposed outside the housing, wherein the conductive pen is moveable between an operational position in which an electrical contact is provided between a first terminal and a second terminal disposed inside the housing, and an off position in which no electrical contact is present between the first terminal and the second terminal, wherein the conductive pen comprises a first actuating part having a first magnet, and wherein the first actuating part and second actuating part form a non-mechanical link by the first and second magnets being disposed at corresponding locations on opposite sides of a wall of the housing such that the magnets slide together along the respective opposite sides of the wall of the housing.
