Abstract

An on-load tap changer module for an on-load tap changer, including a carrier, a diverter switch with a vacuum interrupter and a bridge switch, a selector, a change-over selector, and a drive module, wherein the diverter switch, the selector, and the change-over selector are arranged on the carrier and are activated centrally by the drive module.

First claim

The invention claimed is:

1. An on-load tap changer module for an on-load tap changer, the on-load tap changer module comprising:
a single carrier, which is a single plate;
a diverter switch comprising a vacuum interrupter and a bridge switch;
a selector;
a change-over selector; and
a drive module,
wherein the diverter switch, the selector, and the change-over selector are arranged on the carrier and are configured to be centrally activated by the drive module.

2. The on-load tap changer module as claimed in claim 1 , wherein the drive module comprises a drive shaft with at least one activating element.

3. The on-load tap changer module as claimed in claim 1 , wherein the selector, the change-over selector, and the diverter switch are distributed evenly on the carrier and are arranged around the drive module.

4. The on-load tap changer module as claimed in claim 1 , wherein:
the selector has a plurality of selector contacts,
the selector contacts are arranged in a circle and extend from a first side of the carrier to a second side of the carrier, and
the selector contacts are routed to a first side wall of the carrier.

5. The on-load tap changer module as claimed in claim 1 , wherein the carrier has a connecting element for a transition resistor or a reactor.

6. The on-load tap changer module as claimed in claim 1 , wherein the drive module is arranged on the carrier centrally between the diverter switch, the selector, and the change-over selector, wherein the drive module comprises at least one activating element arranged on a drive shaft, the at least one activating element being configured as a toothed wheel, cam contour, partially toothed wheel, driver, or dual driver, and wherein the at least one activating element is configured to directly or in directly activate the diverter switch, the selector, and the change-over selector.

7. The on-load tap changer module as claimed in claim 1 , wherein the drive module comprises:
a first activating element that is configured to activate a first selector arm of the selector,
a second activating element that is configured to activate a second selector arm of the selector,
a third activating element that is configured to activate the vacuum interrupter of the diverter switch, and
a fourth activating element that is configured to activate the bridge switch of the diverter switch.

8. The on-load tap changer module as claimed in claim 7 , wherein the second activating element is configured to activate the change-over selector.

9. The on-load tap changer module as claimed in claim 7 , wherein the first, second, third, and fourth activating elements are designed as a single piece or multiple pieces.

10. An on-load tap changer module for an on-load tap changer, the on-load tap changer module comprising:
a carrier;
a diverter switch comprising a vacuum interrupter and a bridge switch;
a selector;
a change-over selector; and
a drive module,
wherein the diverter switch, the selector, and the change-over selector are arranged on the carrier and are configured to be centrally activated by the drive module,
wherein the drive module comprises:
a first activating element that is configured to activate a first selector arm of the selector,
a second activating element that is configured to activate a second selector arm of the selector,
a third activating element that is configured to activate the vacuum interrupter of the diverter switch, and
a fourth activating element that is configured to activate the bridge switch of the diverter switch.

11. The on-load tap changer module as claimed in claim 10 , wherein the second activating element is configured to activate the change-over selector.

12. An on-load tap changer module for an on-load tap changer, the on-load tap changer module comprising:
a single carrier, which is a single plate;
a diverter switch comprising a vacuum interrupter and a bridge switch;
a selector;
a change-over selector; and
a drive module,
wherein the diverter switch, the selector, and the change-over selector are arranged on the carrier and are configured to be centrally activated by the drive module,
wherein the drive module is arranged on the carrier centrally between the diverter switch, the selector, and the change-over selector, wherein the drive module comprises at least one activating element arranged on a drive shaft, the at least one activating element being configured as a toothed wheel, cam contour, partially toothed wheel, driver, or dual driver, and wherein the at least one activating element is configured to directly or in directly activate the diverter switch, the selector, and the change-over selector.
