Before the sliding plate 2 slides leftwards, the sliding plate 2 is interlocked with the common side locking lever D1, and the inner bottom surface of the sliding plate 2 presses a locking linkage part D102 of the common side locking lever D1; the sliding plate 2 slides leftwards, the slotted hole of the sliding plate releases the pressing of the locking linkage part D102, the common side locking lever D1 performs anticlockwise rotation due to the action of the common side locking lever return spring D2, and the limiting part D103 of the common side locking lever D1 is contacted with the corresponding stop shaft C203 of the rotating lever C2; and the connection line from the contact point of the first limiting part D103 and the corresponding stop shaft C203 to the axis of the corresponding stop shaft C203 passes through the common side lever rotating shaft D101 of the common side locking lever D1 (namely, the three points are collinear to form a dead point position), so that the position of the rotating lever C2 is locked, the output shaft 3 is locked, and the state locking of the common side power supply closing position is finally completed.

In the manual closing process of the common side power supply, the sliding plate 2 slides leftwards, the common side sliding plate shaft 201 is linked with the common side pulling lever A201 to rotate anticlockwise, and is simultaneously linked with the common side connecting rod A202, so that the movable iron core A101 of the common side electromagnet A1 is linked to act; while the slide plate 2 slides leftwards, the standby side slide plate shaft 202 is linked with the standby side pulling lever B201 to rotate anticlockwise, and is linked with the standby side connecting rod B202, so that the movable iron core B101 of the standby side electromagnet B1 is linked to act; when the common side power supply is switched on, the movable iron core a101 of the common side electromagnet A1 is in a retracted state, and the movable iron core B101 of the standby side electromagnet B1 is in an extended state.

When the switching-on of the common side power supply is completed, the output shaft 3 rotates anticlockwise, the cantilever 303 drives the common switching-off spring 4 to act, and the output shaft 3 receives a clockwise rotation moment due to the spring force of the common switching-off spring 4.

As shown in fig. 16, when the switching-on of the common side power supply is switched to the double-split position, the toggle lever 6 is rotated clockwise to the right when the common side power supply is in a switching-on state, and the sliding plate 2 is linked to slide rightwards by the toggle lever 6; similarly, the standby electromagnet B1 may be energized to retract the movable iron core B101, the movable iron core B101 is linked with the standby pulling lever B201 through the standby connecting rod B202, and the standby pulling lever B201 is rotated clockwise, and during the clockwise rotation of the standby pulling lever B201, the standby sliding plate shaft 202 is linked with the sliding plate 2 to slide rightward; in the process of rightward sliding of the slide plate 2, the first driving part 204 drives the swinging linkage part C101 on the swinging lever C1, so that the swinging lever C1 rotates and swings clockwise around the rotation center of the swinging lever C1; in the process of clockwise swinging of the swinging lever C1, a guide lever C103 arranged on a linkage shaft C102 compresses a main spring C105;

when the toggle lever 6 is in linkage with the slide plate 2 and the swing lever C1 is in the vertical position, the unlocking limiting lever F1 moves upwards under the action of the unlocking limiting lever return spring F3, the contact between the unlocking abdication part F103 and the limiting unlocking shaft C107 on the swing lever C1 is changed into the contact between the unlocking limiting part F102 and the limiting unlocking shaft C107 on the swing lever C1, and the limiting unlocking shaft C107 is limited; similarly, when the standby side electromagnet B1 is energized to enable the movable iron core B101 to be interlocked with the slide plate 2 and enable the swinging lever C1 to be in the vertical position, the standby side electromagnet B1 is energized to enable the stroke of the movable iron core B101 to reach the limit capable of moving, the swinging lever C1 is limited by the unlocking limiting lever F1 to power off the standby side electromagnet B1, and the standby side electromagnet B1 is energized to enable the movable iron core B101 to be reset and extend under the action of the pulling spring shaft B201d and the movable iron core reset spring in the movable iron core B101. When the swing lever C1 is in the vertical position and locked, the main spring C105 is in the compressed maximum force position.

In the process of rightward sliding of the sliding plate 2, the first locking linkage part D102 of the common side locking lever D1 is changed from being positioned in the first slotted hole to being pressed by the bottom surface of the inner side of the sliding plate 2, so that the common side locking lever D1 rotates clockwise; when the common side locking lever D1 rotates clockwise, the limiting part D103 of the common side locking lever is separated from contact with the corresponding stop shaft C203 on the side surface of the rotating lever C2, and the limiting locking of the rotating lever C2 is released; at this time, the output shaft 3 rotates clockwise due to the spring force of the common opening spring 4 and is stabilized to the intermediate position; the middle position at this time is a position where the power supply on the normal side and the power supply on the standby side are not connected, namely a double-divided position.

As shown in fig. 17a,17b and 17C, when the double-split position is switched to the standby side power supply, the unlocking limiting lever F1 is pressed or the unlocking electromagnet F2 is electrified, so that the unlocking limiting lever F1 moves downwards, the limiting of the limiting unlocking shaft C107 on the swinging lever C1 by the unlocking limiting part F102 of the unlocking limiting lever F1 is released, the limiting unlocking shaft C107 on the swinging lever C1 is positioned in the unlocking yielding part F103, the toggle lever 6 is rotated clockwise to the right, and the sliding plate 2 is linked to slide rightwards by the toggle lever 6; similarly, the standby side electromagnet B1 may be energized to retract the movable iron core B101, the movable iron core B101 is linked with the standby side pulling lever B201 by pulling the spring shaft B201d, and the standby side pulling lever B201 is rotated clockwise, and during the clockwise rotation of the standby side pulling lever B201, the standby side sliding plate shaft 202 is linked with the sliding plate 2 to slide rightward; in the sliding process of the sliding plate 2, the first driving part 204 drives the swinging linkage part C101 on the swinging lever C1, so that the swinging lever C1 rotates and swings clockwise around the rotation center; after the swing lever C1 rotates by a certain angle, the maximum compression dead point position of the main spring C105 is destroyed, the spring force of the main spring C105 is released rapidly, and due to the action of the spring force, the main spring C105 rotates clockwise through the guide lever C103 and the swing lever C1 in an acceleration manner; during the rotation of the swing lever C1, the linkage shaft C102 links the linkage hole C202 of the rotation lever C2 and rotates the rotation lever C2 clockwise, and since the rotation lever C2 is mounted to the output shaft 3, the output shaft 3 rotates clockwise and finally rotates in place; when the double-power automatic transfer switch rotates in place, closing action of the standby side power supply of the double-power automatic transfer switch is completed; namely, the double-power automatic transfer switch completes the switching from the double-split position to the standby-side power switching-on, as shown in fig. 18.

Before the sliding plate 2 does not slide rightwards, the inner bottom surface of the sliding plate 2 presses the locking linkage part three E102 of the standby side locking lever E1; the sliding plate 2 slides rightwards, the slotted hole II 206a releases the pressing of the locking linkage part III E102, the standby side locking lever E1 rotates clockwise under the action of the standby side locking lever return spring D2, and the limiting part II E103 contacts with the corresponding stop shaft C203 on the side surface of the rotating lever C2; and the connecting line from the contact point of the second limiting part E103 and the corresponding stop shaft C203 to the axis of the corresponding stop shaft C203 passes through the standby side lever rotating shaft E101 (namely, the three points are collinear to form a dead point position), so that the position locking of the rotating lever C2 is realized, and finally, the state locking of the closing position of the common side power supply is finished.

In the manual closing process of the standby side power supply, the sliding plate 2 slides rightwards, the standby side sliding plate shaft 202 is linked with the standby side pulling lever B201 to rotate clockwise, and meanwhile is linked with the standby side connecting rod B202, so that the movable iron core B101 of the standby side electromagnet B1 is linked to act; while the sliding plate 2 slides rightwards, the common side sliding plate shaft 201 is linked with the common side pulling lever A201 to rotate anticlockwise, and is linked with the common side connecting rod A202, so that the movable iron core A101 of the common side electromagnet A1 is linked to act; when the standby side power supply is switched on, the movable iron core B101 of the standby side electromagnet B1 is in a retracted state, and the movable iron core a101 of the common side electromagnet A1 is in an extended state.

When the switching-on of the common side power supply is completed, the output shaft 3 rotates anticlockwise, the spring mounting shaft 303a on the cantilever 303 drives the common switching-off spring 4 to act, and the output shaft 3 receives a clockwise rotation moment due to the spring force of the common switching-off spring 4.
