<p>The two main switching paths are each formed by series-connected contacts, while two resistive switching paths are formed each by a series connection of two contacts with a resistor. Each resistive switching path is parallel to one main switching path between a common terminal and a selector contact of a tap changer. A connecting line (21) of a diode (22) is connected to the junction point of the contacts (11, 12) of a main switching path (7), as well as to junction points of the contacts (19, 20) of the resistive switching path (10), parallel to the other main switching path (8). The other connecting line (23) of the diode is connected to the junction points of the other main switching path (8) contacts (13, 14), as well as the junction points of the contacts (17, 18) of the resistive path (9) parallel to the first switching path (7).</p> |
