Title:
DISCONNECTOR FOR HIGH-FREQUENCY CURRENT
Document Type and Number:
Japanese Patent JP3769887
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent connecting deficiency at a connecting portion of a disconnector and eliminate intrusion of chips by constituting the disconnector of a dipole structure in which a pair of conductors are disposed opposite to each other via insulating plates, connecting one end of the conductor on a movable side to a power source while connecting one end of the conductor on a fixed side to a load, turning the turning conductor by a first driver, and pressing the pressing conductors by a second driver.
SOLUTION: Turning conductors 6a, 6b are suspended downward in a disconnected state. In this state, when a command for rotating an output shaft of a motor 14 in a certain direction is given, the rotation of the output shaft of the motor 14 is transmitted to a connecting shaft via a pinion gear and a spur gear, and further, to a turning shaft 10 via a worm and a worm wheel 21. Since insulating couplings 11a, 11b are fixed to the turning shaft 10 via a slide key, the turning conductors 6a, 6b are turned in a horizontal direction while being pressed by movable side conductors 2a, 2b by springs 13a, 13b, so that a dog part presses a limit switch 25 so as to stop the motor 14.
