The double-power-supply change-over switch comprises a breaking unit, a rack and a quick change-over device. The frame is installed on the breaking unit, and a first moving contact support, a second moving contact support and a static contact are arranged on the breaking unit.

The quick switching device is mounted to the frame and comprises a drive mechanism comprising a first actuator 1 and a second actuator 2, both of which are preferably electromagnets, which are only movable from the left side of the drawing to the right side of the drawing when energized and return to an initial position under the action of respective return springs when de-energized. The quick switching device further comprises a transmission mechanism, wherein the transmission mechanism is positioned between the driving mechanism and the machine frame and is used for transmitting the force of the driving mechanism to the machine frame and further causing the movable contact support to rotate. The transmission mechanism comprises a first drive member 3, a second drive member 4 and a third drive member 5 pivotally mounted to the frame. In this embodiment, the first driving member, the second driving member and the third driving member are driving gears, and the first driving member is engaged with the second driving member and the third driving member respectively.

The frame 6 is provided with a first spring 61, one end of the first spring 61 is fixed on the frame, and the other end is mounted on the second driving member 4. Specifically, the second driving member 4 is provided with a third recess 41 and a first protrusion 42 located in the third recess 41, the first protrusion 42 being movable along the third recess 41 similarly to the second and fourth posts, and the other end of the first spring is fixed to the first protrusion 42. The first spring 61 is able to store energy in rotation in response to the rotation of the second driver and, after releasing the energy, causes the first movable contact support to move.
The frame 6 is further provided with a second spring 62, one end of the second spring 62 is fixed on the frame, and the other end is mounted on the third driving member 5. Specifically, the third driver 5 is provided with a fourth recess 51 and a second projection 52, and the second projection 52 is movable along the fourth recess 51 similarly to the second and fourth posts, and the other end of the second spring is fixed to the second projection 52. The second spring 62 is capable of storing energy in response to rotation of the third driver and causing movement of the second movable contact support after the energy is released.
Next, the operation of the dual power transfer switch of the present invention is described with reference to fig. 2 to 4.
Fig. 2 shows the dual power transfer switch in a double-split position, in which the first and second actuators are omitted. In the double-split position, as shown in fig. 2, the second post 32 abuts against the right edge of the first recess under the action of the first biasing spring, and the fourth post 35 abuts against the right edge of the second recess under the action of the second biasing spring. The first protruding column, the second protruding column, the third protruding column and the fourth protruding column are symmetrical about the horizontal central axis of the first driving member.
When the dual power transfer switch is switched from the dual-split position to the first power position, the first actuator is energized and moves in a rightward translational motion, which causes the first actuator to abut against the second stud and pulls the first driving member through the second stud 32, causing the first driving member to rotate counterclockwise, thereby causing the second driving member and the third driving member to rotate clockwise. As shown in fig. 5, the first protrusion 42 connected to the first spring 61 is located at the lower end of the third recess, so that clockwise rotation of the second driver directly causes rotational movement of the first spring 61. After the first spring 61 passes a "dead point" (which means that the first spring extends through the pivot center of the second driving member and the fixed point of the first spring on the frame), the first spring 61 releases the stored energy and causes a corresponding movement of the first movable contact carrier from the double-split position to the first power position. When the third driver is rotated clockwise, as shown in fig. 5, the second projection 52 connected to the second spring 62 is located at the upper end of the fourth recess, and therefore, the clockwise rotation of the third driver does not urge the second spring 62 to move, i.e., there is a "backlash" in the third driver. After the dual power transfer switch is switched from the double-split position to the first power position, the first actuator is de-energized and returns to the initial position under the action of its return spring to prepare for the next energization.
When the dual power transfer switch is switched from the first power position to the double split position, the second actuator is energized to move translationally to the right and pulls the first driver through the third post 34, rotating the first driver clockwise, which rotates the second driver and the third driver counterclockwise. In the first power position, as shown in fig. 6, the first projection 42 connected to the first spring 61 is located at the upper end of the third recess, and therefore, the counterclockwise rotation of the third driving member urges the first spring 61 to move. After the first spring 61 passes a "dead point" (which means that the first spring extends through the pivot center of the second driving member and the fixed point of the first spring on the frame), the first spring 61 releases the stored energy and causes a corresponding movement of the first movable contact carrier from the first power position to the double-split position. When the third driver is rotated counterclockwise, as shown in fig. 6, the second protrusion 52 connected to the second spring 62 is located in the fourth recess and does not abut against either end, so that the counterclockwise rotation of the third driver does not push the second spring 62 to move, i.e., there is a "lost motion" in the third driver. After the dual power transfer switch switches from the first power position to the double split position, the fourth post is in the path of the second actuator being normally reset. When the second actuator is powered off, the second actuator moves leftwards under the action of the reset spring, and during the period, the second actuator overcomes the biasing force of the second biasing spring on the fourth stud to enable the fourth stud to move along the second groove, so that the fourth stud moves out of the moving path of the second actuator, and the second actuator is normally reset. It should be understood that the manner of moving the fourth post out of the path of movement of the second actuator is well known in the art and is described only briefly herein and will not be described further.
When the dual power transfer switch is switched from the double-split position to the second power-on position, the second actuator is energized to move rightward, and pulls the first driving member through the fourth stud to rotate the first driving member clockwise, which rotates the second driving member and the third driving member counterclockwise. As shown in fig. 5, the second projection 52 connected to the second spring 62 is located at the upper end of the fourth recess so that counterclockwise rotation of the third driver directly causes rotational movement of the second spring 62. When the second spring 62 passes the "dead point", the second spring 62 releases the stored energy and causes the second movable contact carrier to perform a corresponding movement, switching from the double split position to the second power position. When the second driver is rotated counterclockwise, as shown in fig. 5, the first protrusion 42 connected to the first spring 61 is located at the lower end of the third recess, and therefore, the counterclockwise rotation of the second driver does not push the first spring 61 to move, i.e., there is a "backlash" in the second driver. After the dual power transfer switch is switched from the double-split position to the second power position, the second actuator is de-energized and returns to the initial position under the action of its return spring in preparation for the next energization.
When the dual power transfer switch is switched from the second power position to the double split position, the first actuator is energized to move in translation to the right and pulls the first driving member through the first stud 31, rotating the first driving member counterclockwise, which rotates the second driving member and the third driving member clockwise. In the second power position, as shown in fig. 7, the second projection 52 connected to the second spring 62 is located at the lower end of the fourth recess so that clockwise rotation of the third driver directly causes rotational movement of the second spring 62. When the second spring 62 passes the "dead point", the second spring 62 releases the stored energy and causes the second movable contact carrier to perform a corresponding movement, switching from the second power position to the double-split position. When the second driver is rotated clockwise, as shown in figure 7, the first projection 42 connected to the first spring 61 is located in the third recess and does not abut either end, so that clockwise rotation of the second driver does not urge the first spring 61 to move, i.e. there is a "lost motion" in the second driver.
After the dual power transfer switch switches from the second power-on position to the dual-split position, the second stud is in the path of the first actuator for normal reset. When the first actuator is powered off, the first actuator moves leftwards under the action of the return spring, and during the period, the first actuator overcomes the biasing force of the first biasing spring on the second protruding column, so that the second protruding column moves along the first groove, and moves out of the moving path of the first actuator, and the first actuator is normally reset.
The utility model discloses a quick conversion equipment and dual power transfer switch have been described in detail above with reference to the attached drawing, through the utility model discloses a quick conversion equipment can realize dual power transfer switch fast and switch, has kept the good performance of product simultaneously.
Moreover, the technical features disclosed above are not limited to the combinations with other features disclosed, and other combinations between the technical features can be performed by those skilled in the art according to the purpose of the invention to achieve the aim of the invention.
