Description

Technical Field

[0001] The present invention relates to the technical field of power supply equipment, and particularly to a disconnector drive structure and a switch cabinet. Background Art

[0002] Disconnectors play a crucial role in the power system. They not only ensure the safety of staff but also promote the stable operation of the power system.

[0003] Specifically, disconnectors act as isolators in the circuit. Their design and use purpose are to ensure safety by disconnecting the circuit during equipment maintenance or replacement. However, disconnectors may encounter various problems during actual operation, one of which is overheating of the contact part. This situation may be caused by various reasons, including but not limited to scratches at the connection of the knife blades, which mainly occur during the opening and closing process of the disconnector.

[0004] The existence of scratches may affect the smoothness of the contact part, resulting in poor contact, which in turn increases the contact resistance.

Specific embodiments

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, which can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation manner.

[0047] Please refer to Figures 1 to 11, in the embodiments of the present invention, an isolating switch driving structure includes: a support frame 2, a conductive rod 4, an abutting structure, a rotating disk 13, a driven shaft 15, and a storage assembly. During the movement of the follower sleeve 16, through the cooperation of the first protrusion 1601 and the first arc-shaped groove 2101, and the second protrusion 1602 and the second arc-shaped groove 2201, the abutting plate 7 and the conductive rod 4 can act alternately, so that when the isolating switch is disconnected, the two abutting plates 7 can act first and the conductive rod 4 can act later; when the isolating switch is connected, the conductive rod 4 can act first and the abutting plate 7 can act later. Thus, it effectively avoids the occurrence of friction and scratches between the abutting plate 7 and the conductive rod 4 during the operation of the isolating switch, reduces the risk of heat melting at the connection between the abutting plate 7 and the conductive rod 4 when the circuit is connected, and improves the stability of the power supply system. Specifically as follows:

[0048] An inclined mounting surface 201 is provided on the support frame 2, and a pair of insulators 3 are mounted on the inclined mounting surface 201;

[0049] The conductive rod 4 is rotatably connected to a connecting member 5 provided on one of the insulators 3. Among them, a limiting rod 501 is provided on the connecting member 5. When the limiting rod 501 abuts against the conductive rod 4, the conductive rod 4 is in a state of deflecting towards the support frame 2;

[0050] It should be noted that due to the existence of the inclined mounting surface 201, the conductive rod 4 can have a tendency to move towards the abutting structure under the action of its own gravity without external interference, so that when the conductive rod 4 is connected to the abutting structure, the connection state is more stable. When the conductive rod 4 abuts against the limiting rod 501, the isolating switch is in the disconnected state. At this time, the conductive rod 4 is still in a state of tilting towards the support frame 2, so that when the isolating switch is connected, the conductive rod 4 can act preferentially under the action of its own weight, thereby realizing the preferential positioning of the conductive rod 4 and then the action of the abutting structure, preventing friction between the end of the conductive rod 4 and the abutting structure during the process of connecting the isolating switch, which may cause scratches on the conductive rod 4, and reducing the occurrence of deeper scratches on the conductive rod 4 and heat melting phenomenon after power-on during the process of connecting the isolating switch multiple times.

[0051] Please refer to Figures 5 to 7 , the abutting structure is provided on the other group of insulators 3. Two abutting plates 7 adapted to the end of the conductive rod 4 are provided on the abutting structure. The abutting structure includes a bracket 6 detachably mounted on the insulator 3. Two transverse rods 8 are symmetrically and slidably mounted on the bracket 6. One end of the transverse rod 8 is connected to the abutting plate 7, and a sheave 9 is rotatably mounted at the other end. Further, the above-mentioned abutting plate 7 and transverse rod 8 are both made of conductive materials, such as iron and steel;

[0052] A fitting groove is provided on the side plate 10 slidably connected to the bracket 6. The grooved wheel 9 can roll in the fitting groove to make the two horizontal rods 8 approach or move away from each other. Specifically, a guiding groove 1001 is provided on the side plate 10 along its length direction, and the guiding groove 1001 is slidably connected to a sliding connection part 601 provided on the bracket 6. The fitting groove includes a vertical groove 1002 and an inclined groove 1003 provided on the side plate 10. The vertical groove 1002 is communicated with the inclined groove 1003. When the grooved wheel 9 rolls in the inclined groove 1003, the two horizontal rods 8 can approach or move away from each other.

[0053] When the grooved wheel 9 is at the end of the inclined groove 1003 far from the vertical groove 1002 (the grooved wheel 9 does not move to the end of the inclined groove 1003), the horizontal rod 8 can drive the corresponding two abutting plates 7 to abut against the conductive rod 4. At this time, the disconnecting switch is in the on state. Due to the existence of the storage component, the side plate 10 has a tendency to continue moving away from the support frame 2, and the horizontal rod 8 has a tendency to drive the two abutting plates 7 to continue approaching, so as to ensure the degree of fit between the abutting plate 7 and the conductive rod 4 and prevent an arc from being generated due to a gap between the two, resulting in a thermal melting phenomenon of the abutting plate 7 or the conductive rod 4. When the grooved wheel 9 is in the vertical groove 1002, the two abutting plates 7 are in a state of moving away from each other and separating from the conductive rod 4. At this time, the disconnecting switch is off. Since the length direction of the horizontal rod 8 is perpendicular to the length direction of the vertical groove 1002, when the disconnecting switch is in the off state, the horizontal rod 8 cannot drive the abutting plate 7 to move, thereby improving the position stability between the abutting plate 7 and the conductive rod 4 and preventing the distance between the abutting plate 7 and the conductive rod 4 from being too small, resulting in the generation of an arc.

[0054] Specifically, when disconnecting the disconnecting switch, under the guidance of the guiding groove 1001 and the sliding connection part 601, the side plate 10 will move towards the support frame 2. At this time, the grooved wheel 9 can move towards the vertical groove 1002 along the length direction of the inclined groove 1003, and the grooved wheel 9 can drive the horizontal rod 8 to move away from the conductive rod 4 along the length direction of the horizontal rod 8, so that the two abutting plates 7 can move away from each other. At this time, the abutting plate 7 can separate from the conductive rod 4. Since the abutting plate 7 moves perpendicular to the conductive rod 4, it is ensured that when the abutting plate 7 moves, there will be no friction between the abutting plate 7 and the conductive rod 4, and thus no scratches will be generated on the fitting surface between the abutting plate 7 and the conductive rod 4.

[0055] When making the disconnecting switch conductive, the side plate 10 will move in the reverse direction, and the horizontal rod 8 will drive the two abutting plates 7 to move closer to each other until the two abutting plates 7 abut against the conductive rod 4. Similarly, no scratches will be generated on the fitting surface between the abutting plate 7 and the conductive rod 4.

[0056] With the above settings, when the side plate 10 moves towards or away from the support frame 2, the grooved pulley 9 can drive the abutting plate 7 to move perpendicular to the conductive rod 4 through the cooperation with the vertical groove 1002 and the inclined groove 1003, thereby avoiding relative friction between the abutting plate 7 and the conductive rod 4, reducing the oxidation and rusting speed of the joint surface between the abutting plate 7 and the conductive rod 4 due to friction, and the risk of heat melting between the two.

[0057] Please refer to Figure 4 、 Figure 7 As shown in FIGS. [FIG NUMBERS], the abutting structure further includes a deflecting rod 12 rotatably mounted on the support frame 2. One end of the deflecting rod 12 is connected to the side plate 10 through a fitting kit. The fitting kit includes a first straight groove 1201 arranged along the length direction of the deflecting rod 12, and the first straight groove 1201 is slidably sleeved with a first convex shaft 11 rotatably mounted on the side of the side plate 10. The other end is provided with the connecting groove.

[0058] The rotating disk 13 is rotatably mounted on the support frame 2. Specifically, the rotating disk 13 is connected to a vertical plate provided on the support frame 2. A second convex shaft 1301 is mounted on the rotating disk 13. The second convex shaft 1301 cooperates with the connecting groove provided on the abutting structure, enabling the abutting structure to drive the two abutting plates 7 to approach or move away from each other. The connecting groove includes a second straight groove 1202 provided on the deflecting rod 12 and an arc groove 1203 connected to the second straight groove 1202. The circumferential radius of the arc groove 1203 is the same as the radius of the circular motion of the second convex shaft 1301.

[0059] In the initial state, the second convex shaft 1301 is at the end of the second straight groove 1202 away from the arc groove 1203. In this state, due to the presence of the storage component, the second convex shaft 1301 still has a tendency to move downward in a circular motion following the rotating disk 13 (please refer to Figure 7 ). At this time, one end of the deflecting rod 12 is pressed downward, and the other end is lifted upward, causing the side plate 10 to have an upward movement tendency. Under this tendency, the two abutting plates 7 can maintain close contact with the conductive rod 4, thereby improving the connection stability between the two.

[0060] When the rotating disk 13 moves in the reverse direction, the second convex shaft 1301 will move in a reverse circular motion. At this time, the second convex shaft 1301 will move along the length direction of the second straight groove 1202, and the end of the deflecting rod 12 facing the rotating disk 13 will move away from the support frame 2. At this time, the other end of the deflecting rod 12 will move towards the support frame 2. The deflecting rod 12 can drive the side plate 10 to move towards the support frame 2 through the cooperation of the first convex shaft 11 and the first straight groove 1201, so that the two abutting plates 7 can move away from each other.

[0061] Please note that the [FIG NUMBERS] in the translation of line 7 should be replaced with the actual figure numbers in the original text. Since they are not provided in the given content, I left them as placeholders.When the grooved pulley 9 moves into the vertical groove 1002, the maximum relative distance is reached between the two abutting plates 7. At this time, the second convex shaft 1301 just moves to the end of the second straight groove 1202. In this state, the center of the circular arc groove 1203 is coaxial with the rotation axis center of the rotating disk 13. So that during the continuous rotation of the rotating disk 13, the second convex shaft 1301 can move in the circular arc groove 1203, locking one end of the deflecting rod 12, and improving the position stability between the abutting plate 7 and the conductive rod 4 in this state.

[0062] Please refer to Figures 8 to 11 , the driven shaft 15 is rotatably installed on the support frame 2. Specifically, the driven shaft 15 is rotatably connected to the connecting plate 20 connecting the vertical plate. The driven shaft 15 is respectively connected to the rotation shafts of the rotating disk 13 and the conductive rod 4 through a differential structure. When the driven shaft 15 rotates, it can drive the abutting plate 7 and the conductive rod 4 to act alternately. Further, an operating rod 14 is connected to one end of the driven shaft 15;

[0063] The differential structure includes a follower sleeve 16 coaxially connected to the driven shaft 15. A first driven wheel 21 is rotatably installed coaxially on the follower sleeve 16. The first driven wheel 21 is connected to the rotation shaft of the conductive rod 4 through a second connecting belt 24;

[0064] The differential structure further includes a second driven wheel 22 rotatably connected to the driven shaft 15. The second driven wheel 22 is connected to the rotation shaft of the rotating disk 13 through a first connecting belt 23. Among them, the above-mentioned first connecting belt 23 and second connecting belt 24 are preferably toothed belts;

[0065] A first arc groove 2101 is provided on the side of the first driven wheel 21. A second arc groove 2201 is provided on the side of the second driven wheel 22. The first protrusion 1601 and the second protrusion 1602 provided on the follower sleeve 16 are respectively in sliding fit with the first arc groove 2101 and the second arc groove 2201. It should be noted that the central angle of the first arc groove 2101 is larger than the central angle of the second arc groove 2201;

[0066] In the initial state, the first protrusion 1601 abuts against one side wall of the first arc-shaped groove 2101, and the second protrusion 1602 abuts against one side wall of the second arc-shaped groove 2201. In this state, the end of the conductive rod 4 can abut against the bracket 6, and the abutting plate 7 can abut against the conductive rod 4. At this time, the disconnecting switch is in the conducting state. During the process of the energy storage component storing energy, the driven shaft 15 will move and drive the follower sleeve 16 to move. At this time, the first protrusion 1601 will move along the first arc-shaped groove 2101, and the second protrusion 1602 will move along the second arc-shaped groove 2201. When the energy storage component actively drives the driven shaft 15 to move, since the central angle of the first arc-shaped groove 2101 is larger than that of the second arc-shaped groove 2201, the second protrusion 1602 will first abut against the other side wall of the second arc-shaped groove 2201. The second driven wheel 22 will drive the rotating disk 13 to rotate through the first connecting belt 23. At this time, the two abutting plates 7 will move away from each other until the distance between the two abutting plates 7 is the largest. At this time, the second convex shaft 1301 moves to the end of the second straight groove 1202, and the first protrusion 1601 abuts against the other side wall of the first arc-shaped groove 2101. During the continuous movement of the follower sleeve 16, it can drive the first driven wheel 21 to rotate and drive the conductive rod 4 to deflect by using the second connecting belt 24. At the same time, during this process, the second convex shaft 1301 moves in the arc-shaped groove 1203 to keep the distance between the two abutting plates 7 constant. Based on the above principle, during the process of disconnecting the disconnecting switch, the two abutting plates 7 will move away from each other and separate from the conductive rod 4, and then the conductive rod 4 deflects, that is, the staggered movement of the abutting plate 7 and the conductive rod 4 is realized, effectively preventing relative sliding and friction between the abutting plate 7 and the conductive rod 4 and avoiding the generation of scratches.

[0067] After the conductive rod 4 deflects to a certain angle, the conductive rod 4 will abut against the limiting rod 501. At this time, the position of the conductive rod 4 is locked, and the conductive rod 4 is still in the state of deflecting towards the support frame 2. If it is necessary to connect the disconnecting switch at this time, it is necessary to control the energy storage component to act. During the process of the energy storage component storing energy, as the driven shaft 15 rotates, the conductive rod 4 can deflect in the reverse direction under the action of its own gravity. When the energy storage component actively drives the driven shaft 15 to act, the conductive rod 4 can first abut against the bracket 6, and then the two abutting plates 7 move closer to each other, realizing the prior positioning of the conductive rod 4 and the subsequent positioning of the abutting plate 7, and also preventing relative sliding between the abutting plate 7 and the conductive rod 4.

[0068] With the above settings, during the movement of the follower sleeve 16, through the cooperation of the first protrusion 1601 and the first arc groove 2101, and the second protrusion 1602 and the second arc groove 2201, the abutting plate 7 and the conductive rod 4 can act alternately. When the disconnecting switch is disconnected, the two abutting plates 7 can act first and the conductive rod 4 can act later. When the disconnecting switch is connected, the conductive rod 4 can act first and the abutting plate 7 can act later. Thus, it effectively avoids the friction and scratches between the abutting plate 7 and the conductive rod 4 when operating the disconnecting switch, reduces the risk of heat melting at the connection between the abutting plate 7 and the conductive rod 4 when the circuit is connected, and improves the stability of the power supply system.

[0069] It should be further noted that in order to improve the position stability of the two abutting plates 7 when the driven shaft 15 acts to store energy in the storage and release assembly, damping sleeves can be provided at the rotating shaft of the deflecting rod 12 and the connection between the side plate 10 and the sliding connection part 601. When the driven shaft 15 acts to store energy in the storage and release assembly, the position state between the two abutting plates 7 is more stable, and the excessive resistance of the relative movement between the second driven wheel 22, the driven shaft 15, and the follower sleeve 16 is avoided, so that the second driven wheel 22 directly follows the movement of the follower sleeve 16. On the one hand, it can prevent the generation of electric arcs, and on the other hand, it can avoid the interference between the conductive rod 4 and the abutting plate 7 when the conductive rod 4 is reset.

[0070] Please refer to Figures 8 to 9 , the storage and release assembly is connected to the driven shaft 15, and the storage and release assembly can actively drive the rotation of the driven shaft 15 by storing energy. The storage and release assembly includes two spiral grooves 1501 symmetrically arranged on the driven shaft 15. The two spiral grooves 1501 are connected, and a protrusion 1502 is formed at the position where the two spiral grooves 1501 are connected;

[0071] A connecting sleeve 17 is slidably sleeved on the driven shaft 15. A third convex shaft 1701 is arranged in the connecting sleeve 17, and the third convex shaft 1701 can slide in the two spiral grooves 1501;

[0072] The storage and release assembly further includes an elastic telescopic rod connecting the connecting sleeve 17. The elastic telescopic rod includes a guiding shaft 1702 connected to the connecting sleeve 17 and a guiding sleeve 19 slidably sleeved on the guiding shaft 1702. A spring 18 is arranged between the guiding shaft 1702 and the guiding sleeve 19. Wherein, one end of the guiding sleeve 19 away from the connecting sleeve 17 is connected to the connecting plate 20.

[0073] In the initial state, the spring 18 is in a stretched state. At the same time, the third convex shaft 1701 is at one end (not the end) of one of the spiral grooves 1501 away from the protrusion 1502, causing the driven shaft 15 to have a tendency to continue rotating in one direction. Under this tendency, when the disconnecting switch is in the on state, it can ensure the force exerted by the abutting plate 7 on the conducting rod 4 and the force exerted by the conducting rod 4 on the bracket 6, making the fit between the abutting plate 7 and the conducting rod 4 higher, and at the same time, the position state of the conducting rod 4 is more stable. When the disconnecting switch is off, it can ensure the maximum relative distance between the two abutting plates 7 and the position stability of the conducting rod 4 after deflection (in this state, one end of the conducting rod 4 is in a state of abutting against the limiting rod 501).

[0074] When the driven shaft 15 is rotated by the operating rod 14, the spiral groove 1501 will rotate relative to the connecting sleeve 17, enabling the third convex shaft 1701 to move along the length direction of the spiral groove 1501. At this time, the connecting sleeve 17 moves away from the connecting plate 20, and the spring 18 is further stretched to store elastic potential energy. During this process, although the follower sleeve 16 rotates with the driven shaft 15, the first protrusion 1601 will slide in the first arc groove 2101 (only occurs when disconnecting the disconnecting switch), and the second protrusion 1602 will slide in the second arc groove 2201. That is, during the energy storage stage, the first driven wheel 21 and the second driven wheel 22 will not rotate (only the first driven wheel 21 will not rotate when disconnecting the disconnecting switch).

[0075] After the third convex shaft 1701 moves past the protrusion 1502, the spring 18 can release the elastic potential energy, driving the follower sleeve 16 to move actively, thereby quickly driving the second driven wheel 22 to rotate, enabling the two sets of abutting plates 7 to perform relative movement quickly. By a faster action speed, the generation of electric arcs can be reduced, and overheating at the connection between the abutting plate 7 and the conducting rod 4 can be avoided.

[0076] Through the above settings, on the one hand, it can improve the position stability between the abutting plate 7 and the conducting rod 4 in the off and on states of the disconnecting switch, making the fit between the abutting plate 7 and the conducting rod 4 higher when the disconnecting switch is on, and at the same time, the position state of the conducting rod 4 is more stable. When the disconnecting switch is off, it ensures the maximum relative distance between the two abutting plates 7 and the position stability of the conducting rod 4 after deflection. On the other hand, by releasing the elastic potential energy, it can actively and quickly drive the abutting plate 7 to move, suppressing the generation of electric arcs and avoiding overheating at the connection between the abutting plate 7 and the conducting rod 4.

[0077] As an embodiment of the present invention, a switch cabinet is also proposed, which includes the disconnecting switch driving structure as described above, and also includes the switch cabinet body 1.
