Abstract
A switching module is for an on-load tap-changer. The switching module has: a plate having a first side and a second side that is opposite the first side; a vacuum interrupter; and a bridge switch. The vacuum interrupter is on the first side, and the bridge switch, which is directly behind the vacuum interrupter, is on the second side.
Claims10
A switching module for an on-load tap-changer, the switching module comprising:
- a plate having a first side and a second side that is opposite the first side;
- a vacuum interrupter;
- and
- a bridge switch,
- wherein the vacuum interrupter is on the first side,
- wherein the bridge switch, which is directly behind the vacuum interrupter, is on the second side,
- wherein the vacuum interrupter comprises a first contact and a second contact,
- wherein a first fixed contact is mechanically and electrically connected to the first contact,
- wherein a second fixed contact is mechanically and electrically connected to the second contact,
- wherein the first fixed contact and the second fixed contact extend through the plate from the first side to the second side,
- wherein the bridge switch comprises a movable bridge contact,
- wherein the movable bridge contact is configured to be moved into at least three positions, and
- wherein the bridge contact contacts at least one free end of the first fixed contact and at least one free end of the second fixed contact in each case individually or simultaneously and connects the free end of the first fixed contact and the free end of the second fixed contact to a load take-off lead.
