TAP CHANGER AND VACUUM INTERRUPTER FOR A TAP CHANGER OF THIS KIND |
摘要 |
The invention relates to a tap changer for switching over between winding taps of a tap transformer without interruption, wherein two load branches are provided for each phase which is to be switched and each load branch has a vacuum switching contact, which acts as a main contact and, parallel to said vacuum switching contact, at least one series circuit comprising a transition resistor and in each case a further vacuum switching contact. In this case, in each case one vacuum switching contact of each load branch is structurally combined to form a single vacuum interrupter having two separate, fixed contacts (5, 8), which can be selectively connected, and a single moving contact (4). |
