In the working process of the dual-power automatic transfer switch, the reliability of the transfer and the running stability are directly related to the continuous power supply output state of the power transmission and distribution line; the dual-power automatic transfer switch is provided with two automatic transfer switches of two positions and three automatic transfer switches of three positions; the two-position automatic transfer switch is switched between two states of normal side power supply switching-on (simultaneous standby side power supply switching-off) and standby side power supply switching-on (simultaneous normal side power supply switching-off), so that continuous, stable and reliable electric energy output of a power transmission and distribution line is realized.
The operating mechanism is used as a core part in the dual-power automatic conversion switch, provides kinetic energy during position conversion of the automatic conversion switch, and is linked with a contact system of the automatic conversion switch through an output part of the operating mechanism to convert a closing position state between a common side power supply and a standby side power supply; the operating mechanism of the automatic transfer switch at two positions has two states, which correspond to the common side power switch-on position and the standby side power switch-on position respectively. However, in the automatic transfer switch of two positions in the prior art, locking mechanisms are respectively arranged on the common side and the standby side, and the locking mechanisms on the common side and the standby side are in complementary interference, so that only one of the common side and the standby side is easily locked, and the other side is not locked, so that misoperation occurs.

In this embodiment, when the common side power supply is in the closing position, the position states of the components are as follows: as shown in fig. 2, the operating mechanism is in a state of closing the power supply at the normal side, at this time, the sliding plate 2 is at the leftmost position of the sliding maximum stroke, the normal side sliding plate shaft 201 on the sliding plate 2 is linked with the normal side pulling lever a201 to enable the normal side pulling lever a201 to be at the leftmost position of the sliding maximum stroke, and the normal side pulling lever a201 drives the movable iron core a101 of the normal side electromagnet A1 through the normal side connecting rod a202 to enable the movable iron core a101 to be in a retracted state; meanwhile, when the sliding plate 2 is at the leftmost position of the sliding maximum stroke, the standby side sliding plate shaft 202 on the sliding plate 2 is linked with the standby side pulling lever B201, so that the standby side pulling lever B201 is located at the leftmost position of the sliding maximum stroke, and the standby side pulling lever B201 drives the movable iron core B101 of the standby side electromagnet B1 through the standby side connecting rod B202, so that the movable iron core B101 is in an extended state.
When the operating mechanism is in a state of a common side power supply closing position, the main spring C105 is connected with the swing lever C1 through the guide lever C103 to enable the swing lever C1 to be at a maximum position of anticlockwise rotation; meanwhile, the swing lever C1 is linked with the linkage hole C202 of the rotating lever C2 through the linkage shaft C102 at the lower part of the swing lever C1, and the rotating lever C2 is positioned at the maximum position of anticlockwise rotation; because the rotating lever C2 is mounted on the output shaft 3, the output shaft 3 is at the maximum position of anticlockwise rotation, the position of the output shaft 3 ensures the closing position of the power supply on the common side of the operating mechanism, and the standby opening spring 5 is in a stretched state.

When the common side power supply is switched on when the standby side power supply is switched on, the switching-on is carried out: the toggle lever 6 is rotated clockwise to the right, and the slide 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 through the standby side connecting rod B202, 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 and slides the sliding plate 2 rightward; in the sliding process of the sliding plate 2, a first driving part 204 of the sliding plate is linked with a swinging linkage part C101 on a swinging lever C1, so that the swinging lever C1 rotates and swings clockwise around the rotation center of the swinging lever C1; in the rotation process of the swing lever C1, the main spring C105 is compressed through the guide movement of the guide lever C103 positioned in the guide sleeve C104;
In the process of sliding the slide plate 2 to the right, 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 bracket 1, so that when the common side locking lever D1 rotates clockwise, the first limiting part D103 of the common side locking lever D1 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 common side power opening operation is performed on the operating mechanism.
As shown in fig. 13a and 13b, when the swing lever C1 is rotated clockwise to the vertical state, the center line of the main spring C105 coincides with the rotation center point of the swing lever C1, the main spring C105 is compressed to the maximum state, and the spring force value is also accumulated to the maximum; at the moment, the toggle lever 6 is continuously rotated clockwise or the movable iron core B101 is continuously retracted, the sliding plate 2 is linked with the swinging lever C1 to continuously rotate clockwise, at the moment, the center line of the main spring C105 is changed to the left side of the rotation center point of the swinging lever C1, and the main spring C105 is released; after the main spring C105 is released, it pushes the guide lever C103 and links the swing lever C1 to accelerate the swing lever C1 to rotate clockwise.
In the process of clockwise rotation of the swing lever C1, the linkage shaft C102 is linked with the linkage hole C202 of the rotating lever C2, and the rotating lever C2 overcomes the spring force of the standby brake separating spring 5 to rotate clockwise, and the rotating lever C2 is mounted on the output shaft 3, so that 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; the double-power automatic transfer switch finishes the transfer from the common side power switching-on state to the standby side power switching-on state.
In the process of rightward sliding of the sliding plate 2, the third locking linkage part E102 of the standby side locking lever E1 is pressed by the bottom surface of the inner side of the bracket 1 to be positioned in the second slotted hole, and the standby side locking lever E1 rotates clockwise under the action of the standby side locking lever return spring E2; when the standby side locking lever E1 rotates clockwise, the second limiting part E103 of the standby side locking lever E contacts with the corresponding stop shaft C203 on the side surface of the rotating lever C2 and limits and locks the rotating lever C2; at this time, the connection line from the contact point of the second limit part E103 and the corresponding stop shaft C203 to the axis of the corresponding stop shaft C203 passes through the standby lever rotation shaft E101 of the standby side locking lever E1 (i.e. the three points are collinear to form a dead point position), so as to lock the position of C2, and complete the state locking of the standby side power closing position as shown in fig. 14.
When the standby side power is switched on, the output shaft 3 rotates clockwise, the spring mounting shaft 303a on the cantilever 303 drives the standby switching-off spring 5 to act, and the output shaft 3 receives a counterclockwise rotation moment due to the spring force of the standby switching-off spring 5.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art will appreciate that; the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
