US 11,948,761 B2 · Method for carrying out a switchover of at least two switching means for equipment, and drive system for at least two switching means in equipment

Abstract

A method carries out a switchover of a first switch or at least one second switch for equipment. The method includes receiving, by a controller, a switching signal; selecting, by the controller, the first switch or at least the second switch for switchover on the basis of the switching signal; querying, by the controller, at least one parameter of the first switch or the at least second switch; checking a locking condition on the basis of the at least one queried parameter for the first switch or a locking condition for the at least second switch; and carrying out the switchover by the selected first switch or the at least second switch based upon the corresponding locking condition being met.

Dependent claims

A method of operating a tap-changer of a transformer for carrying out a switchover of a first switch or at least one second switch, the tap-changer comprising the first switch and the at least one second switch, the method comprising:

receiving, by a controller, a switching signal;
selecting, by the controller, the first switch or the at least one second switch for switchover on the basis of the switching signal;
querying, by the controller, at least one parameter of the first switch or the at least one second switch;
checking a locking condition on the basis of the at least one queried parameter for the first switch or a locking condition for the at least one second switch;
and
carrying out the switchover by the selected first switch or the at least one second switch based upon the corresponding locking condition being met,
wherein the first switch is a diverter switch and the at least one second switch comprises a selector.

4 more elements

A tap-changer, the tap changer comprising:

a first switch connected to a first motor via a drive shaft;
at least one second switch being connected to at least one respective second motor via a second drive shaft;
a respective feedback system, which is associated with each of the first motor and the at least one second motor, the respective feedback system being configured to ascertain at least one parameter of the respective one of the first switch or the at least one second switch;
and
a controller, which is connected in a communicating manner to a power section, configured to operate the first switch using the first motor and to operate the at least one second switch using the at least one second motor, and further configured to selectively operate one from the group of the first switch and the at least one second switch based upon a switching signal and upon the corresponding locking condition being met by the at least one determined parameter that is evaluated in the controller,
wherein the first switch is a diverter switch and the at least one second switch comprises a selector.
