| 摘要 | The device is used for locking an access for actuating two switching devices of high-voltage switchgear with the aid of a drive shaft transmitting drive force onto the two switching devices. In order to increase the operational safety of the high-voltage switchgear with little outlay, the locking device comprises a closing disk which is fastened on the drive shaft, a rocker bar arrangement containing at least four rocker bars, and a slider. The slider can be moved, on-site, into two positions, the first of which releases an access for the actuation on-site and blocks an access for the actuation from a remote location, and the second of which blocks the access for the on-site actuation and releases the access for the remote actuation. | ||||||
