Abstract

Apparatus for switching a high-current power supply, for example for transportable melting systems in melting and remelting plants, with a stationary apparatus part and a movable apparatus part, a contact surface between the stationary and the movable part as well as a device for locking the two parts, the contact surface (2d) on the stationary part (S) being preferably in the form of a hemisphere (2a) and the corresponding contact surface (3d) on the movable part (M) being preferably configured as a conical inside surface (3a) and the contacts being joinable forcibly with one another by means of a clamping device, the clamping device consisting for example of a centering and drawing bolt (2b) and of a corresponding ball clamping device, and that the clamping device is electrically insulated by means of insulators (7, 12) from the current-carrying contacts.
