    摘要： An electric switch for application to high- and very high-voltage circuit breakers and switches comprising a flexible toroidal helical spring (8) placed in a groove of a control rod (1) carrying a movable resistance-insertion contact (2), and springs (4) placed about the movable resistance-insertion contact to cause the springs to be compressed until a certain value is reached, at which value the movable resistance-insertion contact causes the flexible toroidal helical spring (8) to deform under pressure enabling the movable resistance-insertion contact (2) to be withdrawn. Among other uses, the switch is suitable for use in a resistance-inserting device that does not need additional mechanical moving parts.For application to high- and very high-voltage circuit breakers and switches.

    摘要： A circuit including arcing contacts is connected in parallel with main contacts of a disconnector to facilitate interruption of a loop current caused through the disconnector when switching main bus bars in a power station. A switching surge suppression resistor is adapted to be inserted in and removed from the circuit of the arcing contacts. Plural pairs of arcing contacts are provided in the circuit of arcing contacts.
