Description

The invention relates to a diverter switch for an on-load tap changer of a variable transformer and a permanent main switch and a disconnector for a diverter switch of an on-load tap changer and generally a switch for a switching device.

DE 10 2010 015 051 A1 describes a mechanical switching contact which has at least two pivotable between two end positions, electrically conductively interconnected contact fingers, which are operatively connected via multi-lever joints with a rotatable switching shaft, which has circumferential guide slots for actuating the multi-lever joints and coupled therewith deflection of the contact fingers. This known switching contact is designed as a circuit breaker, circuit breaker or switch, in which the two contact fingers are mounted on an electrically conductive common axis which is arranged parallel to the switching shaft, each of the two contact fingers a separate mechanical, electrically conductive stop to form the respectively connected End positions of the disconnector, disconnector or changeover switch is assigned. The first contact finger is in a first end position of the switch contact at its stop and establishes an electrically conductive connection between the axis and the stop, while the second contact finger is lifted from its associated stop. The first contact finger is lifted in the second end position of the switching contact of the associated stop, while the second contact finger rests against the associated stop and makes an electrically conductive connection between the axis and the stop. If a current is passed through a contact finger and the abutting contact with it, between them repulsive forces arise, which depend on the current and at an on-load tap-changer, which per switch contact is designed for short-time currents of 10 kA and more, can be at least 100 N. The switching contact must apply a correspondingly high contact force in order to be able to hold the contact finger securely against the stop. The axle is constantly attached to the contact fingers.

The moving contacts are jointly movable by rotating the switch main shaft relative to the contact ring and the fixed contact such that they bear a first position in which they bear against the contact ring and the fixed contact, and a second position in which they bear against the contact ring Fixed contact are separated, can take. In the first position are the contact ring and the fixed contact between the moving contacts. The contact ring is constantly on the moving contacts.
