Abstract
A circuit breaker and/or earthing switch are disclosed wherein a rotatable spindle nut, which is mounted in a spindle housing, displaces a spindle in a translatory manner, thus displacing contact elements of the switching device. The spindle actuates a contact pin that is configured in a contact carrier by a connection yoke that is common to all phases or poles and an isolating bar for each phase or pole.
Claims9
A spindle drive for a switch disconnector and/or grounding switch, in which a spindle nut which is mounted in a spindle nut housing such as it can rotate moves a spindle translationally and during which process contact-making elements of the switching device can be moved translationally, wherein the spindle operates a contact pin, which is guided in a contact mount, via a connecting yoke, which is shared by all the phases and poles, and an isolation rod for each phase and pole.
A spindle drive for a switch disconnector and/or grounding switch, in which a spindle nut which is mounted in a spindle nut housing such as it can rotate moves a spindle translationally and during which process contact-making elements of the switching device can be moved translationally, wherein the spindle operates a contact pin, which is guided in a contact mount, each pole having a separate associated spindle with a separate drive.
