Abstract
An on-load tap changer is for uninterrupted diverter switch operation. The on-load tap changer includes: a first module having a first module shaft; and a second module having a second module shaft. The first module shaft is configured to actuate the first module. The second module shaft is configured to actuate the second module. The first module shaft and the second module shaft are mechanically coupled to one another in such a way that the first module shaft is configured to drive the second module shaft and the second module is configured to be actuated with a time delay with respect to the first module.
Claims11
An on-load tap changer for uninterrupted diverter switch operation, the on-load tap changer comprising:
- a first module comprising a first module shaft;
- a second module comprising a second module shaft;
- and
- a third module comprising a third module shaft;
- wherein:
- the first module shaft is configured to actuate the first module;
- the second module shaft is configured to actuate the second module;
- the first module shaft and the second module shaft are mechanically coupled to one another in such a way that the first module shaft is configured to drive the second module shaft and the second module is configured to be actuated with a time delay with respect to the first module, and
- the third module shaft is configured to actuate the third module and the second module shaft and the third module shaft are mechanically coupled to one another in such a way that the second module shaft is configured to drive the third module shaft and the third module is configured to be actuated with a second time delay with respect to the second module.
An on-load tap changer for uninterrupted diverter switch operation, the on-load tap changer comprising:
- a first module comprising a first module shaft;
- a second module comprising a second module shaft;
- a drive configured to actuate the first module and the second module by causing the first module shaft and the second module shaft to turn;
- a first insulating shaft having a first end and a second end, the first end of the first insulating shaft being coupled to the drive and the second end of the first insulating shaft being coupled to the first module shaft;
- and
- a second insulating shaft having a first end and a second end, the first end of the second insulating shaft being coupled to the first module shaft and the second end of the second insulating shaft being coupled to the second module shaft,
- wherein the first module shaft is configured to actuate the first module;
- wherein the second module shaft is configured to actuate the second module;
- wherein the first module shaft and the second module shaft are mechanically coupled to one another in such a way that the first module shaft is configured to drive the second module shaft and the second module is configured to be actuated with a time delay with respect to the first module,
- wherein each of the first module shaft and the second module shaft have a first end and a second end,
- wherein the on-load tap changer further comprises a respective first connecting pin at the first end of each of the first module shaft and the second module shaft and positioned at a first axial orientation, and
- wherein the on-load tap changer further comprises a respective second connecting pin at the second end of each of the first module shaft and the second module shaft and positioned at a second axial orientation.
