    摘要： The present disclosure provides a vacuum interrupter pole for a circuit breaker and its associated electrical device. The vacuum interrupter pole comprises: a vacuum interrupter; an insulation supporting shell for accommodating and supporting the vacuum interrupter and having a top wall and side walls defining a U shape, where the vacuum interrupter is adapted to be placed within an interior space limited by the side walls via an opening side of the U shape; and a conductive connector with a first end and a second end, wherein the first end is fastened between the top wall and the vacuum interrupter and electrically connected to the vacuum interrupter, and the second end is adapted to act as a supporting point for a moving knife component of an isolation switch that is electrically connected with the circuit breakers.

    摘要： The present invention relates to a medium voltage or high voltage equipment, comprising:
    - a first part (20);
    - a second part (10);
    - a field control element (100);

    wherein the first part is formed from a conducting material;
    wherein the second part is formed from an insulating material;
    wherein the first part is connected to the second part at a junction;
    wherein the medium voltage or high voltage equipment is configured such that the first part can be held at an operational voltage;
    wherein the field control element is formed from a conducting material; and
    wherein the field control element is located in contact with an outer surface of the first part, and wherein the field control element is located adjacent to the junction.

    摘要： The present invention relates to a medium or high voltage circuit breaker (1). The circuit breaker comprises a first vacuum interrupter (10), a second vacuum interrupter (20), and a heat sink (30). The heat sink is in thermal contact with a fixed contact carrier (12) of the first vacuum interrupter. The heat sink is in thermal contact with a fixed contact carrier (22) of the second vacuum interrupter.
