Switch drive
First Claim
1. Switch drive assembly, comprising a switch having a contact and a control shaft for actuating said contact and switching substantially currentlessly, and a drive having a drive motor, a flywheel accumulator connected to said drive motor for receiving a charge from said drive motor immediately prior to a switching process, said flywheel accumulator being coupled to said control shaft for discharging during the switching process and executing the previously initiated switching process, said drive motor acting as a generator for generation of a flywheel-driven voltage supply;
- and an electrical control being driven by said flywheel-driven voltage supply for controlling the switching process during discharge of said flywheel accumulator.

Abstract
A switch drive assembly includes a switch having a contact and a control shaft for actuating the contact and switching substantially currentlessly, and a drive having a drive motor, a flywheel accumulator connected to the drive motor for receiving a change from the drive motor immediately prior to a switching process, the flywheel accumulator being coupled to the control shaft for discharging during a switching process and executing a previously initiated switching process, the drive motor acting as a generator for generation of a self-sufficient voltage supply during discharge of the flywheel accumulator.

6. Switch drive assembly, comprising a switch having a contact and a control shaft for actuating said contact and switching substantially currentlessly, and a drive having a drive motor, a flywheel accumulator connected to said drive motor for receiving a charge from said drive motor immediately prior to a switching process, said flywheel accumulator being coupled to said control shaft for discharging during the switching process and executing the previously initiated switching process, said drive motor acting as a generator for generation of a flywheel-driven voltage supply;
- and an electrical control being driven by said flywheel-driven voltage supply for controlling the switching process during discharge of said flywheel accumulator, the switch including a gear disposed on said control shaft, and the drive including another shaft rigidly interconnecting said drive motor and said flywheel accumulator, and a pinion loosely disposed on said other shaft and meshing with said gear, said pinion being fixed in place during charging of said flywheel accumulator and being coupled to said other shaft during discharging of said flywheel accumulator.
