Drive for a switch disconnector with C O switching capacity
View Patent ↗Exemplary embodiments relate to a drive for a switch disconnector having C or O switching capacity and a switching pin acting as switching contact. A spindle drive is driven by an electric motor and has a spindle nut. An actuating element, which is loaded by a compression spring and is capable of pivoting about a fixed pivot point, is acted upon by the spindle nut. The actuating element for its part interacts with an actuating apparatus which actuates the switching pin.
1. A drive for a switch disconnector comprising:
a closed and off (C and O) switching capacity with a switching pin acting as a switching contact;
a spindle drive driven by an electric motor having a spindle nut; and
an actuating element which is loaded by a compression spring and is capable of pivoting about a fixed pivot point and is acted upon by the spindle nut,
wherein the actuating element interacts with an actuating device that actuates the switching pin, and
wherein the actuating element is a double switching fork having a first switching fork and a second switching fork separated from each other by a fork opening and each of the first and second switching forks being at a predetermined angle with respect to each other, the double switching fork being configured to be engaged by the spindle nut, and to act upon an actuating disk or an actuating cylinder.
2. The drive as claimed in claim 1 , wherein the actuating element is flexibly connected to the compression spring.
3. The drive as claimed in claim 1 , wherein the compression spring is formed by a spring assembly which is bistably mounted.
4. The drive as claimed in claim 2 , wherein the compression spring is mounted on a side opposite the connecting point of the actuating element.
5. The drive as claimed in claim 4 , wherein the compression spring is mounted on the side opposite the connecting point of the actuating element via an immovable mount.
6. The drive as claimed in claim 1 , wherein the actuating device is formed by an actuating disk or an actuating cylinder, a peripheral surface of the actuating disk or actuating cylinder engages with an actuating shaft in order to actuate the switching pin.
7. The drive as claimed in claim 6 , wherein a face surface of the actuating disk or of the actuating cylinder is provided with at least one concentrically arranged actuating bolt which can be acted upon by the actuating element for the purpose of rotationally actuating the actuating cylinder.
8. The drive as claimed in claim 2 , wherein the actuating device is formed by an actuating disk or an actuating cylinder, a peripheral surface of the actuating disk or actuating cylinder engages with an actuating shaft in order to actuate the switching pin.
9. The drive as claimed in claim 8 , wherein a face surface of the actuating disk or of the actuating cylinder is provided with at least one concentrically arranged actuating bolt which can be acted upon by the actuating element for the purpose of rotationally actuating the actuating cylinder.
10. The drive as claimed in claim 3 , wherein the actuating device is formed by an actuating disk or an actuating cylinder, a peripheral surface of the actuating disk or actuating cylinder engages with an actuating shaft in order to actuate the switching pin.
11. The drive as claimed in claim 10 , wherein a face surface of the actuating disk or of the actuating cylinder is provided with at least one concentrically arranged actuating bolt which can be acted upon by the actuating element for the purpose of rotationally actuating the actuating cylinder.
12. The drive as claimed in claim 4 , wherein the actuating device is formed by an actuating disk or an actuating cylinder, a peripheral surface of the actuating disk or actuating cylinder engages with an actuating shaft in order to actuate the switching pin.
13. The drive as claimed in claim 12 , wherein a face surface of the actuating disk or of the actuating cylinder is provided with at least one concentrically arranged actuating bolt which can be acted upon by the actuating element for the purpose of rotationally actuating the actuating cylinder.
14. The drive as claimed in claim 1 , wherein the compression spring has a spring force which establishes the C and O switching capacity of the drive.
15. The drive as claimed in claim 1 , wherein the compression spring has a spring force which establishes the C and O switching capacity of the drive.
