Abstract
A diverter switch, which is for an on-load tap-changer, includes a housing; and a carrier. The carrier has elements configured to carry out a diverter switch operation. The carrier and the elements are at least partly encapsulated in the housing.
Claims8
1:
- A diverter switch for an on load tap changer, the diverter switch comprising:
- a housing;
- and
- a carrier with comprising elements configured to carry out a diverter switch operation;
- wherein the carrier and the elements are at least partly encapsulated in the housing.
2 more elements
2:
- The diverter switch as claimed in claim 1, wherein:
- the housing is configured in a shape of a tank or cup;
- the housing has a first region;
- and
- the carrier is at least partly arranged in the first region.
2 more elements
3:
- The diverter switch as claimed in claim 1, wherein:
- the carrier is configured as a circuit board.
4:
- The diverter switch as claimed in claim 1, wherein:
- the carrier and the elements are at least partly or completely encapsulated or potted with a casting resin or a silgel in the housing.
5:
- The diverter switch as claimed in claim 1, wherein:
- the elements for carrying out the diverter switch operation comprise at least one semiconductor switching element, a varistor, or a controller.
6:
- The diverter switch as claimed in claim 1, the diverter switch further comprising:
- an optical communication interface and electrical contacts, which are at least partly encapsulated or potted and arranged on the carrier.
7:
- The diverter switch as claimed in claim 1, wherein;
- the diverter switch is connected to a controller via an optical communication interface and is connected to a selector via electrical contacts.
8:
- A method for producing a diverter switch as claimed in claim 1, the method comprising:
- in a first step, the carrier with elements configured to carry out a diverter switch operation is arranged in a first region of the housing;
- in a second step, the carrier with the elements is at least partly potted in the first region such that the carrier is connected to the housing;
- and
- in a third step, the housing with the potted carrier and the elements is dried.
