SWITCHING MODULE, AND ON-LOAD TAP CHANGER COMPRISING A SWITCHING MODULE

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.

Description

Claims

1. 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; anda bridge switch,wherein the vacuum interrupter is on the first side, andwherein the bridge switch, which is directly behind the vacuum interrupter, is on the second side.

2. The switching module for the on-load tap-changer as claimed in claim 1, wherein: the vacuum comprises a first contact and a second contact,the first contact has-comprises a first fixed contact, andthe second contact has-comprises a second fixed contact, andthe first fixed contact and the second fixed contact extend through the plate from the first side to the second side.

3. The switching module for the on-load tap-changer as claimed in claim 2, wherein: the bridge switch has-comprises a movable bridge contact,the movable bridge contact is configured to be moved into at least three positions,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.

4. The switching module for the on-load tap-changer as claimed in claim 2, wherein: the first fixed contact and the second fixed contact are formed from, in each case, two electrically conducting wires,a fixed end of the first fixed contact and a fixed end of the second fixed contact are connected mechanically and in an electrically conducting manner to the first contact and the second contact,a free end of the first fixed contact and a free end of the second fixed contact are arranged on the second side to surround the vacuum interrupter.

5. The switching module for the on-load tap-changer as claimed in claim 1, wherein: the bridge contact comprises a housing with at least one contact lamella,the at least one contact lamella is connected to a load take-off lead in an electrically conducting manner.

6. The switching module for the on-load tap-changer as claimed in claim 5, wherein: the bridge contact with the housing and the contact lamella, and free ends of the first fixed contact and the second fixed contact form the bridge switch.

7. The switching module for the on-load tap-changer as claimed in claim 1, the switching module further comprising: a bearing block which serves as a guide for the first contact and as a mounting for a rocker lever.

8. The switching module for the on-load tap-changer as claimed in claim 1, wherein: the vacuum interrupter and the bridge switch are configured to be actuated via a common drive shaft.

9. The on-load tap-changer with the switching module as claimed in claim 1, wherein: a selector and a change-over selector are arranged on the plate.

10. The on-load tap-changer as claimed in claim 9, the on-load tap-changer comprising: a transition resistor or a connecting piece to a throttle on the plate.
