The description of "first" and its variants is merely for the purpose of distinguishing between the parts and does not limit the scope of the invention, which can be written as "second" and so on without departing from the scope of the invention.
The drawings in the present specification are schematic views to assist in explaining the concept of the present invention, and schematically show the shapes of the respective portions and the mutual relationships thereof.
Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to fig. 1 to 14.
The utility model discloses a dual supply change over switch divides disconnected unit and quick conversion equipment including. The breaking unit is provided with a first moving contact support, a second moving contact support and a fixed contact. The breaking units are well known to the person skilled in the art and will not be described in further detail herein.
The quick switching device is arranged on a shell of the dual-power transfer switch and comprises a driving mechanism, wherein the driving mechanism comprises a first actuator 1 and a second actuator 2. Preferably, the first actuator and the second actuator are both electromagnets. The first actuator 1 is provided with a first pusher 101 and the second actuator 2 is provided with a second pusher 201. Further, a first return spring (not shown) is provided to the first actuator, and a second return spring (not shown) is provided to the second actuator.
As shown in fig. 1, when the first actuator 1 is energized, the first pusher 101 may move downward (i.e., in a third direction); when the first actuator 1 is de-energized, the first push member 101 may be reset, i.e. moved up to the initial position, by the first return spring. When the second actuator 2 is energized, the second pusher 201 can move downwards; when the second actuator 2 is de-energized, the second pusher 201 may be reset, i.e. moved upwards to the initial position, by the second return spring.
The quick switching device also comprises a transmission mechanism for transmitting force to the breaking unit so as to realize switching between the two power supplies. The transmission comprises a first drive member 3 pivotably arranged on the housing, a second drive member 4 and a third drive member 5 displaceably arranged on the housing, and a fourth drive member 6 fixedly mounted on the first drive member. For example, the first driver 3 and the fourth driver 6 are provided on the housing by a common pivot shaft, or the first driver 3 and the fourth driver 6 are formed as an integral structure. In this way, the first driver and the fourth driver may rotate together about the pivot axis.
As shown in fig. 2 and 3, the second driving member 4 and the third driving member 5 are racks having toothed edges, and the fourth driving member 6 is a gear. When the gear rotates, the gear drives the second driving part or the third driving part to move upwards or downwards relative to the shell by meshing with the toothed edge.
As shown in fig. 2, the transmission mechanism may further include a first elastic member 7 having one end disposed on the second driving member 4 and the other end fixed to the housing, and a second elastic member 8 having one end disposed on the third driving member 5 and the other end fixed to the housing.
For example, when the second driving member 4 is displaced downwards relative to the housing, the first elastic member 7 can rotate clockwise around its fixed point on the housing and store energy, and after the first elastic member passes through a "dead point" (when the line connecting the two legs of the first elastic member is perpendicular to the direction of movement of the second driving member), the first elastic member releases energy to drive the second driving member to further displace downwards relative to the housing. When the second driving member 4 is displaced upward, the first elastic member 7 rotates past the "dead point" and then drives the second driving member 4 to be further displaced upward. The working principle of the second elastic member is similar to that of the first elastic member, and is not described in detail herein.
As shown in fig. 3, the transmission mechanism may further include a third elastic member 9 having one end disposed on the second driving member 4 and the other end fixed to the housing, and a fourth elastic member 10 having one end disposed on the third driving member 5 and the other end fixed to the housing. The working principle of the third elastic element 9 and the fourth elastic element 10 is similar to that of the first elastic element and will not be described in detail here.
For example, the first to fourth elastic members may be metal torsion springs.
As shown in fig. 4, the first driving member 3 has a disc-like form on which a first stud 31, a second stud 32, a third stud 33 and a fourth stud 34 are arranged. The first and third studs 31, 33 are symmetrically arranged with respect to the centre line of the first drive member (i.e. a line passing vertically through the centre of the disc-shaped first drive member in fig. 4), and the second and fourth studs 32, 34 are symmetrically arranged with respect to the centre line of the first drive member. The first driver 3 is further provided with a first recess 35 and a second recess 36. For example, the first recess and the second recess are arranged to both penetrate the first driver. The first stud 31 is fixedly mounted on the first drive member 3. The second stud 32 is located in the first recess 35 and is mounted to the pivot shaft of the first driver by a first link (on the rear side of the first driver, not shown) and is thus movable along the first recess 35. The first driver is provided with a first biasing spring (not shown) which biases the first link so that the second post 32 abuts a first end wall (shown as the right end wall in the drawings) of the first recess 35. The third stud 33 is fixedly mounted on the first driver 3 and the fourth stud 34 is located in the second recess 36, mounted to the pivot shaft of the first driver by a second link (on the back of the first driver, not shown) and is thus movable along the second recess 36. A second biasing spring (not shown) is provided on the first driver member and applies a biasing force to the second link to urge the fourth post 34 against a second end wall (shown as the left end wall in the drawings) of the second recess 36.
Next, the operation of the dual power transfer switch of the present invention will be described with reference to fig. 4 to 14, and the transfer device of the switch includes only the first elastic member and the second elastic member.
Fig. 4 to 9 → 4 "show the operation of the dual power transfer switch" dual-split position → first power position → dual-split position ".
Fig. 4 shows the fast switching apparatus when the dual power transfer switch is in the double split position. At this time, the first driving member 3 is at the zero position, the second protrusion 32 abuts against the left first end wall of the first groove 35, and the fourth protrusion 34 abuts against the right second end wall of the second groove 36.
Fig. 4 to 7 show the quick changeover device when the dual power changeover switch is switched from the double split position to the first power position.
As shown in fig. 4-5, when the first actuator 1 is energized, the first pushing member 101 moves in the third direction (i.e., downward) for a lost motion and then contacts the second stud 32 of the first driving member 3. In the process, the first pusher accumulates energy and the first driver 3 remains stationary.
As shown in fig. 5-6, the first pushing member 101 rotates the first driving member 3 in the first direction (i.e., counterclockwise) from the zero position to the first intermediate position by pushing the second stud 32 due to the abutment of the second stud 32 against the first end wall on the left side of the first groove. The first driving member 3 drives the second driving member 4 to displace along the third direction (i.e. downward) through the fourth driving member 4 rotating together, so as to drive the first elastic member 7 to rotate along the second direction (i.e. clockwise) and store energy in the first elastic member.
As shown in fig. 6-7, the first elastic member 7 releases energy after passing through the "dead point" to further displace the second driving member 4 in the third direction, so that the fourth driving member 6 further rotates the first driving member 3 in the first direction from the first intermediate position to the first position. In this process, the rotation of the fourth driving member 4 rotates the first movable contact, thereby turning on the first power source.
When the first driver 3 is in the first intermediate position (as shown in fig. 6), the first actuator 1 is de-energized. In case of a loss of power to the first actuator 1, the first pusher 101 can be reset by the action of the first return spring, as shown in fig. 7, the first pusher 101 having returned to its initial position.
Fig. 7 to 9 and 4 show the quick changeover device when the dual power changeover switch is switched from the first power position to the double split position.
As shown in fig. 7-8, the second actuator 2 is energized and the second pusher 201 moves in the third direction for a lost motion and contacts the third post 33 of the first driver 3. In the process, the second pusher accumulates energy and the first driver 3 remains stationary.
As shown in fig. 8-9, since the third stud 33 is fixed on the first driving member 3, the second pushing member 201 rotates the first driving member 3 in the second direction from the first position to the second intermediate position by pushing the third stud. The first driving member 3 drives the second driving member 4 to displace along the fourth direction (i.e. upward) through the fourth driving member 6 rotating together, so as to drive the first elastic member 7 to rotate along the first direction and store energy in the first elastic member.
As shown in fig. 9 and 4, after the first elastic member 7 passes through the "dead point", the energy is released to further displace the second driving member 4 in the fourth direction, so that the fourth driving member 6 further rotates the first driving member 3 in the second direction from the second intermediate position to the zero position. In this process, the rotation of the fourth driving member 4 rotates the first movable contact, thereby disconnecting the first power supply.
When the first driver 3 is in the second intermediate position (as shown in figure 9) the second actuator 2 is de-energised. In case of loss of power to the second actuator 2, the second pusher 201 may be reset by the action of a second return spring, as shown in fig. 4, the second pusher 201 having returned to its initial position.
As shown in fig. 9, the fourth stud 34 may block the second pusher 201 when the second pusher 201 is returned upward. Thus, the fourth stud 34 can move away from the second end wall to the right of the second groove 36 to avoid blocking the movement of the second pusher 201. After the second pusher is reset, the fourth stud 34 may again abut against the second end wall on the right side of the second groove 36 under the action of the second biasing spring.
The first intermediate position and the second intermediate position of the first driver 3 are different. When the third driving piece is positioned at the first middle position, the first elastic piece just rotates to pass a dead point along the clockwise direction; when the third driving member is located at the second intermediate position, the first elastic member rotates in the counterclockwise direction just beyond the "dead point".
Fig. 4 → fig. 10 to fig. 14 → fig. 4 "shows the operation of the dual power transfer switch" dual-split position → second power position → dual-split position ".
Fig. 4, 10 to 12 show the quick changeover device when the dual power changeover switch is switched from the double-split position to the second power-on position.
As shown in fig. 4 and 10, when the second actuator 2 is energized, the second pushing member 201 moves in the third direction (i.e., moves downward) for a lost motion and then contacts the fourth stud 34 of the first driving member 3. In this process, the second pusher accumulates energy and the first driver remains stationary.
As shown in fig. 10-11, the second pushing member 201 rotates the first driving member 3 in the second direction (i.e., clockwise) from the zero position to the third intermediate position by pushing the fourth stud 34 due to the abutment of the fourth stud 34 against the second end wall on the right side of the second groove 36. The first driving member 3 drives the third driving member 5 to displace in the third direction (i.e. downwards) through the fourth driving member 6 rotating together, so as to drive the second elastic member 8 to rotate in the first direction (i.e. anticlockwise) and store energy in the second elastic member.
As shown in fig. 11-12, the second elastic member 8 releases energy after passing through the "dead point" to further displace the third driving member 5 in the third direction, so that the fourth driving member 6 further rotates the first driving member 3 in the second direction from the third intermediate position to the second position. In this process, the rotation of the fourth driving member 4 rotates the second movable contact, thereby turning on the second power source.
When the first driver is in the third intermediate position (as shown in figure 11) the second actuator 2 is de-energised. In case of loss of power to the second actuator 2, the second pusher 201 may be reset by the action of a second return spring, as shown in fig. 12, the second pusher 201 having returned to its initial position.
Fig. 12-14 and 4 show the fast switching apparatus when the dual power transfer switch is switched from the second power position to the double split position.
As shown in fig. 12-13, when the first actuator 1 is energized, the first pusher 101 moves in the third direction for a lost motion and then contacts the first stud 31 of the first driver 3. In the process, the first pusher accumulates energy and the first driver remains stationary.
As shown in fig. 13-14, since the first stud 31 is fixed on the first driving member 3, the first pushing member 101 drives the first driving member 3 to rotate from the second position to the fourth intermediate position in the first direction by pushing the first stud. The first driving member 3 drives the third driving member 5 to displace along the fourth direction (i.e. upwards) through the fourth driving member 6 rotating together, so as to drive the second elastic member 8 to rotate along the second direction and store energy in the second elastic member.
As shown in fig. 14 and 4, after the second elastic member 8 passes through the "dead point", the energy is released to further displace the third driving member 5 in the fourth direction, so that the first driving member 3 is further rotated in the first direction from the fourth intermediate position to the zero position by the fourth driving member 6. In this process, the rotation of the fourth driving member 4 rotates the second movable contact, thereby disconnecting the second power supply.
When the first driver 3 is in the fourth intermediate position (as shown in fig. 14), the first actuator 1 is de-energized. In case of a loss of power to the first actuator 1, the first pusher 101 can be reset by the action of the first return spring, as shown in fig. 4, the first pusher 101 having returned to its initial position.
As shown in fig. 14, the second stud 32 may block the first pusher 101 as the first pusher 101 returns upward. Thus, the second stud 32 can be moved away from the left first end wall of the first recess 25 to avoid blocking the movement of the first pusher. After the first pusher has been reset, the second stud 32 can again abut against the first end wall on the left side of the first recess 25 under the action of the first biasing spring.
The third and fourth intermediate positions of the first driver 3 are different. When the first driving piece is positioned at the third middle position, the first elastic piece rotates along the anticlockwise direction just to pass a dead point; when the first driving member is located at the fourth intermediate position, the first elastic member is rotated just beyond the "dead point" in the clockwise direction.
