It is noted that the terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
In one preferred embodiment of the present application, as shown in fig. 1 to 14, a double-action switch device includes a mounting base 1, a mounting cavity 100 is provided inside the mounting base 1; the switch component 2 and the linkage mechanism 3 are arranged in the mounting cavity 100; so that the entire double-acting switching device is fixedly mounted by means of the mounting 1. The switch assembly 2 is arranged at the lower part of the mounting cavity 100, and the switch assembly 2 comprises a cover 21, an upper feeler lever part 22 and a lower feeler lever part 23; the housing 21 is in sliding fit with the mounting cavity 100, the upper contact rod member 22 is slidably mounted on the upper portion of the housing 21, and the lower contact rod member 23 is mounted on the lower portion of the housing 21 and is in fit connection with the housing 21. The double-acting switch device is arranged in a high-voltage circuit, and the high-voltage circuit can be closed or opened through opening or closing the switch component 2. Specifically, the high-voltage circuit can be closed or opened by the contact or separation of the upper contact rod part 22 and the lower contact rod part 23. And the mounting frame 12 is fixedly mounted on the mounting seat 1, and the linkage mechanism 3 is mounted on the mounting frame 12 and is positioned above the switch component 2. The linkage mechanism 3 is respectively connected with the upper feeler lever part 22 and the housing 21, so that the linkage mechanism 3 can drive the upper feeler lever part 22 and the housing 21 to synchronously move towards or away from each other, and the lower feeler lever part 23 can synchronously move along with the housing 21 in the moving process of the housing 21; and the upper contact rod part 22 and the lower contact rod part 23 are driven by the linkage mechanism 3 to be mutually contacted or separated to close or open the high-voltage circuit. The upper feeler lever part 22 and the housing 21 are driven by the linkage mechanism 3 to synchronously move in the opposite direction or in the opposite direction so as to further realize the synchronous opposite direction or in the opposite direction of the upper feeler lever part 22 and the lower feeler lever part 23, thereby realizing the double-acting operation of the on-off or the on-off of the high-voltage circuit, further effectively shortening the time of the on-off or the on-off of the switch component 2, and protecting the use safety and prolonging the service life of the double-acting switch device.
It can be understood that, after the mounting base 1 is vertically mounted, the upper end of the mounting base 1 is provided with an upper terminal 400; meanwhile, the upper end of the upper feeler lever part 22 is provided with a connecting plate 500, and the connecting plate 500 is a copper plate and has certain elastic deformation capacity; the lower end of the upper terminal 400 may be connected to the connection plate 500, and the upper end of the upper terminal 400 is inserted into a high voltage circuit. The lower end of the lower feeler lever member 23 may extend to the outside of the lower end of the mounting base 1 and may be connected to the lower terminal of the high-voltage circuit by a connecting plate 500 made of a copper plate. Therefore, in the process of contacting or separating the upper feeler lever part 22 and the lower feeler lever part 23, the upper feeler lever part 22 and the lower feeler lever part 23 can move through the elastic deformation of the connecting plate 500, so that the problem that the upper feeler lever part 22 and the lower feeler lever part 23 cannot move due to rigid connection is avoided.
It will also be appreciated that the double-action switchgear of the present application can be used as a vacuum interrupter, as well as a conventional circuit breaker. When the vacuum circuit breaker is used as a vacuum circuit breaker, the upper part of the installation cavity 100 is also provided with a disconnecting switch, the disconnecting switch is respectively connected with the upper wiring terminal 400 and the connecting plate 500 at the upper end of the upper feeler lever part 22, and meanwhile, the disconnecting switch is also in driving connection through the linkage mechanism 3, so that when the vacuum circuit breaker is switched on and off, the linkage mechanism 3 can drive the switch component 2 to be switched on and off firstly and then drive the disconnecting switch to be switched off; when the vacuum circuit breaker is closed, the linkage mechanism 3 can drive the disconnecting switch to be closed firstly and then drive the switch component 2 to be closed. The specific structure of the disconnector and the specific connection to the linkage 3 are prior art in this field and are not described here.
In this embodiment, as shown in fig. 5, 7, and 11 to 14, the lower end of the upper contact rod member 22 and the upper end of the lower contact rod member 23 are provided with contacts 200. The upper and lower contact rod members 22 and 23 can be opened or closed by the contact 200.
In this embodiment, as shown in fig. 1 to 6, 11 and 12, the lower end of the installation cavity 100 is provided with a guide seat 11; the side of the mounting frame 12 adjacent to the casing 21 is provided with a through hole 120. The lower part of the housing 21 is in sliding fit with the guide seat 11, the upper end of the housing 21 is in sliding fit with the through hole 120 by being provided with an upper extension sleeve 211, and the housing 21 is connected with the linkage mechanism 3 by the upper extension sleeve 211, so that the housing 21 can be driven by the linkage mechanism 3 to perform axial stable movement.
In one embodiment of the present application, as shown in fig. 3, 6, 7, 13 and 14, the lower end of the housing 21 is provided with a lower extension 212, while the lower end of the mount 1 is provided with a guide sleeve 13 communicating with the guide base 11. The lower rod section of the lower feeler lever part 23 passes through the lower extension sleeve 212 and the guide sleeve 13 in succession. And the lower rod section of the lower feeler lever member 23 is respectively connected with the lower extension sleeve 212 and the guide sleeve 13 through a deflection structure, so that in the process that the lower feeler lever member 23 moves synchronously with the housing 21, the lower feeler lever member 23 generates relative movement along the movement direction of the housing 21 through the deflection structure, and further the opposite or back movement of the lower feeler lever member 23 and the upper feeler lever member 22 is accelerated, so as to further shorten the time for opening or closing the high-voltage circuit by the upper feeler lever member 22 and the lower feeler lever member 23.
Specifically, as shown in fig. 3, 6, 7, 13 and 14, the deflecting structure includes a first sliding groove 130, a second sliding groove 2120, a first slider 231 and a second slider 232. The first sliding slot 130 is obliquely arranged on the inner wall of the guide sleeve 13, and the second sliding slot 2120 is obliquely arranged on the inner wall of the lower extension sleeve 212; the inclination angle of the first sliding slot 130 is greater than that of the second sliding slot 2120; the first slider 231 and the second slider 232 are disposed at an interval on the sidewall of the lower trolley part 23, so that the first slider 231 and the second slider 232 are respectively engaged with the first sliding slot 130 and the second sliding slot 2120. Therefore, during the movement of the cover 21, the lower feeler lever member 23 deflects in the movement direction of the cover 21 and simultaneously generates a relative movement in the same direction as the movement direction of the cover 21 by the cooperation of the first slider 231 and the second slider 232 with the first slide groove 130 and the second slide groove 2120, respectively.
The deflecting structure may be disposed in such a manner that the first and second sliding grooves 130 and 2120 are obliquely disposed on the side wall of the lower trolley bar part 23; the inclination angle of the first sliding slot 130 is greater than that of the second sliding slot 2120; the first slider 231 is disposed on the inner wall of the guiding sleeve 13, and the second slider 232 is disposed on the inner wall of the lower extending sleeve 212, such that the first slider 231 is engaged with the first sliding slot 130, and the second slider 232 is engaged with the second sliding slot 2120.
It will be appreciated that when the switch assembly 2 opens the high voltage circuit, the upper feeler lever member 22 moves vertically upwards in the axial direction under the drive of the linkage 3; the housing 21 can drive the lower feeler lever part 23 to synchronously move vertically downwards along the axial direction under the driving of the linkage mechanism 3; and during the downward movement of the housing 21, the lower feeler lever member 23 can be deflected by the deflecting structure and can move downward relative to the housing 21 while being deflected, thereby further shortening the time required for the upper feeler lever member 22 and the lower feeler lever member 23 to be separated to a certain distance. When the switch assembly 2 closes the high-voltage circuit, the upper contact rod part 22 moves vertically downwards along the axial direction under the driving of the linkage mechanism 3; the housing 21 can drive the lower feeler lever part 23 to move vertically upwards along the axial direction synchronously under the driving of the linkage mechanism 3; and during the process of moving the housing 21 upwards, the lower feeler lever part 23 can deflect through the deflection structure and generate the upwards movement relative to the housing 21 while deflecting, thereby further shortening the time required for the upper feeler lever part 22 to contact with the lower feeler lever part 23.
Taking the example that the first slider 231 and the second slider 232 are disposed on the lower feeler lever member 23 in the deflecting structure, the following description is made by specific parameters: the distance between a first slide block 231 and a second slide block 232 arranged on the side wall of the lower feeler lever part 23 is set to be L; the first slide groove 130 is inclined at an angle β, and the second slide groove 2120 is inclined at an angle α.
As shown in fig. 13, when the switch assembly 2 is in the closed state, the upper contact rod member 22 and the lower contact rod member 23 are in contact connection through the contact 200, and the distance between the upper end of the lower contact rod member 23 and the bottom of the inner cavity of the housing 21 is X.
As shown in fig. 14, when the switch assembly 2 is opened and closed, the upper feeler lever member 22 is vertically moved upward by the driving of the linkage 3, while the cover 21 is synchronously vertically moved downward by the driving of the linkage 3. During the downward movement of the housing 21, the lower feeler lever member 23 is connected to the second slide slot 2120 via the second slide block 232, so that the lower feeler lever member 23 can synchronously vertically deflect and move downward along with the housing 21. At any deflection angle, if the radial distance from the initial position of the first slider 231 and the second slider 232 is R, the downward movement distance of the first slider 231 relative to the first sliding chute 130 is Rtan β; likewise, the downward movement distance of the second slider 232 relative to the second runner 2120 is Rtan α, and since the inclination angle β of the first runner 130 is larger than the inclination angle α of the second runner 2120, the value of Rtan β is larger than Rtan α, that is, the relative distance between the first runner 130 and the second runner 2120 in the deflecting direction is gradually increased.
Because the mounting seat 1 is fixed, the position of the first sliding slot 130 is always unchanged, and thus when the lower touch rod assembly 23 moves down along the housing 21, the distance between the first sliding slot 130 and the second sliding slot 2120 is gradually reduced, but the distance between the first sliding block 231 and the second sliding block 232 is kept unchanged, so that the lower touch rod assembly 23 can only perform deflection sliding along the first sliding slot 130 and the second sliding slot 2120 by the first sliding block 231 and the second sliding block 232 respectively, so that the lower touch rod assembly 23 can perform deflection downward movement relative to the housing 21, and the gradually reduced distance between the first sliding slot 130 and the second sliding slot 2120 is balanced by the increased relative distance between the first sliding slot 130 and the second sliding slot 2120 corresponding to the deflection downward movement along the deflection direction.
When the switch assembly 2 is completely switched off, the distance between the upper end of the lower feeler lever member 23 and the bottom end of the inner cavity of the housing 21 is Y, i.e. the lower feeler lever member 23 moves downwards by a distance X-Y with respect to the housing 21. I.e., the upper contact rod member 22 and the housing 21, at a constant moving speed, it is possible to obtain a desired specific distance between the upper contact rod member 22 and the lower contact rod member 23 by the relative movement of the lower contact rod member 23 with respect to the housing 21 with a further reduction of the moving distance, thereby further reducing the time required for the switch assembly 2 to be completely opened.
When the switch assembly 2 is closed from the open state, the process of opening and closing the switch assembly 2 can be reversed.
In one embodiment of the present application, as shown in fig. 4, 8-12, the linkage mechanism 3 includes a manipulating member 31, a driving member 32, a first linkage plate 33, and a second linkage plate 34. Wherein the driving part 32 is rotatably mounted on a supporting seat 121 arranged at the top of the mounting frame 12 through the middle part; the first linkage plate 33 and the second linkage plate 34 are rotatably arranged on the mounting frame 12 through the middle parts; the upper ends of the first linkage plate 33 and the second linkage plate 34 are connected with the lower end of the driving part 32, and the lower ends of the first linkage plate 33 and the second linkage plate 34 are respectively connected with the upper end of the upper feeler lever part 22 and the upper end of the housing 21. One end of the operating component 31 is connected with the driving device, and the other end of the operating component 31 is connected with the upper end of the driving component 32, so that the operating component 31 can drive the driving component 32 to rotate around the supporting seat 121 under the driving of the driving device, and further, the first linkage plate 33 and the second linkage plate 34 can be driven to rotate in opposite directions respectively through the rotation of the driving component 32, and the upper touch rod component 22 and the housing 21 can be pulled to move in the opposite directions or in the opposite directions respectively.
It should be noted that, in the present embodiment, reference is made to the mounting direction of the mounting bracket 12 for the upper and lower ends of the respective components of the link mechanism 3. The mounting frame 12 is arranged in a direction perpendicular to the axial direction of the switch assembly 2; therefore, the upper part along the installation direction of the installation frame 12 is the upper end, and the lower part along the installation direction of the installation frame 12 is the lower end.
It will be appreciated that the drive means is prior art in the art and may be a drive motor or a drive cylinder or the like. When the switch component 2 needs to switch on or off the high-voltage circuit, the driving device can drive the driving component 32 to rotate through the driving control component 31, and then drive the first linkage plate 33 to rotate anticlockwise and drive the second linkage plate 34 to rotate clockwise through the driving component 32, so that the upper touch rod component 22 can be driven to vertically move upwards through the anticlockwise rotation of the first linkage plate 33, and the second linkage plate 34 can drive the lower touch rod component 23 to synchronously vertically move downwards through the clockwise rotation of the housing 21. When the switch assembly 2 needs to close a high-voltage circuit, the first linkage plate 33 and the second linkage plate 34 can respectively rotate clockwise and counterclockwise under the driving of the driving part 32, so as to drive the upper feeler lever part 22 to move vertically downwards and drive the housing 21 and the lower feeler lever part 23 to move vertically upwards.
In this embodiment, the specific structural shapes and sizes of the driving member 32, the first linkage plate 33 and the second linkage plate 34 are designed by those skilled in the art according to specific practical requirements, so that there are many specific embodiments of the driving member 32, the first linkage plate 33 and the second linkage plate 34, and a preferred embodiment thereof will be described below.
As shown in fig. 8 to 12, the middle portion of the driving member 32 is rotatably connected to the first rotating hole 1210 formed on the supporting seat 121 through the third pin 322. The upper end of the driving part 32 is hinged with one end of the operating part 31 through a second pin 321; the lower end of the driving member 32 is hinged to the upper ends of the first and second linkage plates 33 and 34, respectively, by a fourth pin 323.
The middle part of the first linkage plate 33 is rotatably connected with a second rotating hole 123 arranged on one side, far away from the switch component 2, of the upper part of the mounting frame 12 through a fifth pin shaft 332, the upper end of the first linkage plate 33 is connected with a fourth pin shaft 323 through a first connecting groove 331, and the lower end of the first linkage plate 33 is connected with a first pin shaft 221 arranged at the upper end of the upper touch rod part 22 through a second connecting groove 333, so that the upper touch rod part 22 axially moves under the driving of the first linkage plate 33.
The middle part of the second linkage plate 34 is rotatably connected with the rotating pin 122 arranged at one side of the upper part of the mounting frame 12 close to the switch component 2 through a third rotating hole 342; the upper end of the second coupling plate 34 is connected to the fourth pin shaft 323 through the third connection groove 341, and the lower end of the second coupling plate 34 is connected to a pin 2110 provided at an end side wall of the upper extension sleeve 211 through the fourth connection groove 343, so that the housing 21 is axially moved by the second coupling plate 34.
The specific working process of this embodiment: as shown in fig. 11 to 12, when the switch assembly 2 needs to disconnect the high-voltage circuit, the driving part 32 is driven by the operating part 31 to rotate clockwise around the third pin 322, and in the process of rotating the driving part 32, the driving part is respectively in press fit with the first connecting groove 331 on the first linkage plate 33 and the third connecting groove 341 on the second linkage plate 34 through the fourth pin 323 at the lower end, so as to apply a moment to the upper end of the first linkage plate 33 in a counterclockwise direction relative to the fifth pin 332, and further, the lower end of the first linkage plate 33 rotates counterclockwise to drive the upper contact rod part 22 to move vertically upward; meanwhile, a moment in a clockwise direction with respect to the third rotation hole 342 is applied to the upper end of the second linkage plate 34, and the lower end of the second linkage plate 34 rotates clockwise to drive the housing 21 to move vertically downward. Similarly, when the switching element 2 is required to switch off the high voltage circuit, the above process is reversed.
In this embodiment, as shown in fig. 4, 11 and 12, the lower side wall of the mounting bracket 12 is provided with a guide groove 124 along the axial direction of the switch assembly 2, the first pin 221 can be connected with the guide groove 124 in a sliding fit manner, and the guide groove 124 can prevent the upper contact rod part 22 from being subjected to deflection resistance during the movement process, so as to reduce the wear generated when the upper contact rod part 22 moves.
It can be understood that, since the movement of the first linkage plate 33 is a rotation around the fifth pin 332, the force applied to the first pin 221 by the lower end of the first linkage plate 33 during the rotation can be decomposed into a component parallel to the axial direction of the upper feeler lever member 22 and a component perpendicular to the axial direction of the upper feeler lever member 22, wherein the component parallel to the axial direction of the upper feeler lever member 22 can be used to drive the upper feeler lever member 22 to move axially, and the component perpendicular to the axial direction of the upper feeler lever member 22 can deflect and bend the upper feeler lever member 22 during the movement of the upper feeler lever member 22, thereby increasing the wear of the upper feeler lever member 22 and the upper extension sleeve 211 of the housing 21. By the sliding fit of the first pin shaft 221 and the guide groove 124, the vertical component of the force of the first linkage plate 33 can be offset by the press fit of the first pin shaft 221 and the side wall of the guide groove 124, so that the upper feeler lever part 22 can only receive the axial component of the force.
In this embodiment, as shown in fig. 5, 11 and 12, the upper end of the upper lever member 22 is connected to the first pin 221 through the pulling part 220. The drawing part 220 may be an insulating material, and a connection plate 500 at the upper end of the upper trolley part 22 is provided at a position where the drawing part 220 is connected to the upper trolley part 22. Meanwhile, the cover 21 is made of an insulating material, so that the linkage mechanism 3 and the switch assembly 2 can be prevented from being electrically contacted by the cover 21 and the traction portion 220. In addition, the actuating element 31 can likewise be provided with an insulating section in order to insulate it from the drive element 32.
In order to insulate the lower contact rod member 23 from the mounting seat 1, the mounting seat 1 may be made of an insulating material, or an insulating layer may be disposed on an outer side wall of the lower contact rod member 23.
It should be noted that the above-described insulating structure provides only one possible embodiment, and is not the only embodiment. The electrical design and insulation design that may be involved in the present application are understood to be common general knowledge and are not the focus of the discussion of the present application, but this does not prevent them from becoming an implicit technical feature of the present application.
It should be noted that the double-acting switch device of the present application may be designed as a vacuum interrupter (i.e., a vacuum interrupter), or may be a switch with other arc extinguishing modes or a common switch, which mainly depends on the specific structure of the housing 21 and the arc extinguishing medium filled in the housing 21.
The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and these changes and modifications are intended to be within the scope of the application as claimed. The scope of protection claimed by this application is defined by the following claims and their equivalents.
