Title:
HIGH-SPEED SWITCH
Document Type and Number:
WIPO Patent Application WO/2020/091250
Kind Code:
A1
Abstract:
The present invention relates to a high-speed switch. In the present invention, one actuator (30) provides a driving force in one direction to drive a driving shaft (33), and a guide pin (18) installed in a frame (10) is guided to a cam groove (24) of a cam (20) rotatably installed on the driving shaft (33), thereby generating movement and rotation of the cam (20). An elastic member (42) is supported at the end portion of the driving shaft (33) to provide a restoring force in the direction opposite to the driving force provided by the actuator (30). When the guide pin (18) is positioned in a closed part (26) or an open part (28) of the cam groove (24), a position of a movable electrode of a circuit breaker connected to the driving shaft (33) is installed, and thus an on/off operation may be generated. In the present invention, there are advantages such as the number of components of the high-speed switch being minimized, since only one actuator (30) is used to perform a switching action and one elastic member (42) is used to provide a force to maintain the on state and the off state.
