[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch operating device used for a power pole switch or the like.

[0002]

2. Description of the Related Art A conventional switch operating device, when automatically operated, is held by a spring energy and a mechanical latch mechanism at the time of closing and closing, and energizes a solenoid coil according to a closing and closing command. The latch mechanism is released, and closing and closing are performed by the spring force of the spring.

In the case of manual operation, the latch mechanism is released by another latch release mechanism, and the operation is performed by a handle.

[0004]

In the case of the above-mentioned conventional apparatus, when the automatic operation is performed, the stored energy of the spring is held by a latch mechanism, and the latch mechanism is released by excitation of a solenoid coil, and the switch is turned on and off. Therefore, there is a problem that a latch mechanism and a solenoid coil are required, and the structure becomes complicated.

Further, there is a problem that a manual operation requires a separate latch release mechanism for releasing the latch mechanism.

In view of the foregoing, the present invention simplifies the structure by eliminating the need for a latch mechanism and a solenoid.
It is an object of the present invention to provide a switch operating device that can be easily operated manually without the need for a latch release mechanism.

[0007]

In order to solve the above-mentioned problems, a switch operating device of the present invention has a central portion fixed to an operating shaft and rotates in a closing direction by a forward rotation of a motor.

A fixed operating body, a driving lever rotatably supported on the operation shaft, a support pin provided on the driving lever, a spring provided between the pins, and a driving lever provided on the driving lever A driving roller, a main shaft for turning on and off a switch by rotation, a main shaft lever having a base fixed to the main shaft, and a tip end of the main shaft lever, and the driving roller is loosely inserted. Opening and closing In the closing state and the closing state, the closing stopper and the closing stopper with which the closing part and the breaking part of the driving lever abut, respectively, and in the closing state where the breaking part abuts on the breaking stopper. A closing switch which is turned on immediately before a dead point of the spring at the time of closing which is located on a line connecting the operating shaft and the support pin; In the closing state in which the abutment contacts the closing stopper, the operating body that moves in the blocking direction abuts, and the energy-storing pin is located on a line connecting the operating shaft and the support pin. The switch is turned on just before the dead point, and the switch is turned on when the closing switch or the closing switch is turned on to stop the rotation of the motor. An electromagnetic brake for holding the stored state of the spring immediately before the dead point of the spring at the time or the dead point of the spring at the time of disconnection, wherein the electromagnetic brake is activated by a closing command or a disconnecting command to the switch. When the spring is turned off, the motor is rotated in the closing direction or the shutoff direction, and the spring energy storage lever is rotated in the closing direction or the shutoff direction via the rotating plate and the operating shaft. The release lever rotates the drive lever in the closing direction or the closing direction, and rotates the main shaft in the closing direction or the closing direction via the driving roller, the long hole and the main shaft lever, thereby closing or closing the switch. It is something to do.

Therefore, in the shut-off state in which the shut-off portion of the drive lever abuts the shut-off stopper, the rotation of the motor rotates the rotary plate to which the operating shaft is fixed, and also rotates the spring energy storage lever to close the shut-off lever. The actuating body that moves in the direction turns on the closing switch, and the energy-saving pin is on the line connecting the operating shaft and the support pin. In the closing state where the closing part of the drive lever abuts the closing stopper, the shutoff switch is turned on by the operating body that moves in the shutoff direction, and the energy storage pin is located on the line connecting the operation shaft and the support pin. Since the motor was turned off just before the dead point at the time to put the spring in the charged state, and the charged state at the time of closing and closing was held by the electromagnetic brake, the latch was used. Without using a configuration and solenoid coil, it is possible to energizing the spring, it is possible to simplify the structure.

According to a second aspect of the present invention, there is provided the operating device, wherein the operating lever has a base fixed to the operating shaft; a closing locking portion and a blocking locking portion formed on the operating lever; A connecting shaft rotatably provided on the axis of the operating shaft and having a handle for manual operation detachably mounted thereon, a connecting lever having a base fixed to the connecting shaft, and a connecting lever implanted on the connecting lever; A connection pin positioned between the locking portions, and a return spring connected to the rotation lever to position the connection pin at a predetermined position, wherein the rotation of the connection shaft causes the connection lever or the connection pin to rotate. The operating shaft is rotated in the closing direction or the blocking direction via the both locking portions and the operating lever.

Therefore, by rotating the connecting shaft, the connecting lever is rotated, and the connecting pin located between the closing locking portion and the blocking locking portion of the operation lever is brought into contact with one of the locking portions. Since the operating shaft is rotated in the closing direction or the closing direction via the operating lever in contact with the operating shaft, the manual operation can be easily performed simply by operating the handle mounted on the connecting shaft.
