The current distribution is achieved mechanically by a device (A) in which a current-carrying shaft (1) with a laterally arranged convex carbon contact (2) rotates and successively contacts a desired number of circularly arranged concave carbon brushes (3). In this process, the current is rapidly routed through the respective brushes (3) via power cables to the respective exposure zones and then completely interrupted. The special feature here is that the rotating convex carbon contact (2) is slightly larger or longer than the stationary concave carbon brushes. This allows the nearest carbon brush to make minimal contact even while the main current is still flowing into the current brush – see Figure 1. The amount of current transferred to the nearest carbon brush is so small that no sparking occurs upon initial contact.Similarly, with further rotation, at the end of the contact time the carbon contact has only a small point of contact with the carbon brush, while the main current is already flowing at the subsequent carbon brush – see drawing 2. Due to the small current and the smooth transition, no sparking occurs during the break-off.

The current-carrying vertical axis is driven directly or indirectly on the opposite upper side by a frequency-controlled electric motor (8) and is separated from the drive system by an insulator (9).The adjustable rotational speed allows the current pulses, and consequently the pause times, to be made shorter or longer. The housing can ideally be designed to be gas-tight with plastic cable glands that are gas-tight up to a pressure of 10 bar. The rotating shaft is fitted with a mechanical seal and is also gas-tight. The housing can then be filled with an inert gas. 3 The gas must be filled to completely prevent any sparking. The gas SF6 (sulfur hexafluoride), previously used for such applications in control cabinets, wind turbines, and electrical installations, should not be used due to its extreme environmental hazards.
