Description
Technical Field
[0001] This invention relates to the field of switchgear technology, specifically to a double-layer removable switchgear with rapidly adjustable stationary contacts and its adjustment method. Background Technology
[0002] Switchgear, as the "joint" of the power system, bears the heavy responsibility of opening, closing, controlling, and protecting the circuits during power generation, transmission, distribution, and energy conversion. Based on the circuit breaker installation method, it can be divided into two main categories: "removable" and "fixed." Removable switchgear consists of a fixed cabinet and a movable trolley: stationary contacts are arranged on the cabinet, and moving contacts are correspondingly arranged on the trolley. Through the precise engagement or disengagement of the moving and stationary contacts, and in conjunction with the circuit breaker inside the trolley, the circuit is switched on and off.
[0003] Due to the influence of assembly precision or environmental vibration during actual production and use, the position of the contact may deviate from the expected position. In order to achieve precise connection between the moving and stationary contacts, the positions of the moving and stationary contacts need to be calibrated. Traditional methods rely on manual adjustment, which is inefficient.
[0004] To address the aforementioned issues, prior art CN108075379B mentions an adjustment device for a withdrawable switchgear. This device involves mounting a stationary contact adjustment body on a contact arm base, pushing a bracket to bring the adjustment body into contact with the stationary contact on the switchgear, adjusting the stationary contact until it aligns with a first adjustment hole, and then fixing the stationary contact in place. While this method improves adjustment efficiency, it requires a stationary contact adjustment body to calibrate the stationary contact position, limiting it to operation only under power-off conditions and making it unsuitable for situations where the stationary contact is energized during operation. Furthermore, to enhance protection, switchgear typically includes a damper to prevent electric shock to users, further complicating visual adjustment by operators. Summary of the Invention
[0005] The purpose of this invention is to provide a double-layer switchgear with a rapidly adjustable stationary contact and an adjustment method, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a double-layer switchgear with rapid adjustment of the stationary contact, comprising: a switchgear body, wherein a handcart is disposed within the switchgear body; a moving contact disposed on the handcart, the moving contact being adapted to a stationary contact disposed within the switchgear body; further comprising: a cross slide structure disposed on the inner wall of the switchgear body and connected to the stationary contact, wherein a support plate is connected to the cross slide structure; and an abutment mechanism disposed on the support plate, the abutment mechanism comprising a lateral movement component and a pressure application component, the lateral movement component being capable of...

[0007] As a further embodiment of the present invention: the cross slide structure includes two sets of longitudinal guide members symmetrically arranged in the switch cabinet body and a horizontal guide member arranged horizontally and capable of sliding along the length direction of the longitudinal guide members. An electrical connection module is slidably installed on the horizontal guide member, and the electrical connection module connects the stationary contact and the support plate.
[0008] As a further embodiment of the present invention: the traverse assembly includes an electric telescopic rod fixedly installed inside the switch cabinet body, a traverse plate connected to the actuating end of the electric telescopic rod, a guide groove provided along the length of the traverse plate, and multiple sets of guide wheels rotatably installed on the support plate capable of rolling within the guide groove; the traverse assembly also includes an inclined surface provided at the end of the traverse plate; the support plate is also provided with an inclined groove, and a coaxial wheel set is rotatably arranged within the inclined groove.
[0009] As a further embodiment of the present invention: the coaxial wheel assembly includes a first grooved wheel, a second grooved wheel, and an abutting wheel coaxially arranged. The first grooved wheel can roll within the inclined groove, the abutting wheel abuts against the inclined surface, and the second grooved wheel is connected to the pressure-applying component. A second cylindrical spring is connected to the shaft of the first grooved wheel, and the end of the second cylindrical spring away from the first grooved wheel is connected to the support plate. When the inclined surface acts on the abutting wheel, the first grooved wheel can move along the inclined groove, so that the second grooved wheel drives the pressure-applying component to operate.
[0010] As a further embodiment of the present invention: the pressure application component includes a limiting sleeve fixedly installed on the support plate and a connecting frame slidably installed on the limiting sleeve. One end of the connecting frame is provided with a vertical groove, and the second grooved wheel can roll in the vertical groove. The pressure application component also includes an abutting part provided at the other end of the connecting frame, and the abutting part abuts and adapts to a damping plate installed in the switch cabinet body.
[0011] As a further embodiment of the present invention: the connecting frame is provided with a limiting groove along its length direction, and a limiting block is provided on the inner wall of the limiting sleeve. The limiting groove and the limiting block cooperate to keep the limiting sleeve and the connecting frame axially locked.
[0012] As a further embodiment of the present invention: the fitting structure includes a straight groove and a spiral groove arranged along the axial direction of the transverse rod, the straight groove and the spiral groove being connected; the fitting structure also includes a convex shaft disposed inside the deflection plate shaft, the convex shaft being able to slide within the straight groove and the spiral groove; a first cylindrical spring is also sleeved inside the transverse rod, one end of the first cylindrical spring being connected to the end of the transverse rod, and the other end being connected to the deflection plate.
[0013] As a further embodiment of the present invention: the misaligned structure includes a sliding connection part that is rotatably connected to the pivot of the transverse rod, the sliding connection part being able to slide along the length direction of the support plate, and the sliding connection part being provided with a hysteresis sleeve that is slidably connected to the moving end of the electric telescopic rod; the misaligned structure also includes a convex ring provided at the moving end of the electric telescopic rod, the convex ring being abutting and adapted to the hysteresis sleeve.
[0014] A method for adjusting a double-layer withdrawable switchgear with rapidly adjustable stationary contacts as described above includes the following steps: Step 1: Move the handcart to the front of the switchgear body using the external support device. As the handcart enters the switchgear body by pushing the external support device, align the through hole on the deflection plate with the moving contact. At this time, the stationary contact will follow the movement of the deflection plate until the moving contact is inserted into the through hole, at which point the moving contact and the stationary contact are coaxial. Step 2: The movement of the lateral component drives the movement of the pressure application component to fix the stationary contact relative to the switch cabinet body; Step 3: The lateral movement component continues to operate, causing the deflection plate to first separate from the moving contact, and then deflect 90°. At this point, the deflection plate can be misaligned with the handcart. Step 4: Push the handcart toward the inside of the switch cabinet body until the moving contact and stationary contact engage, thus locking the handcart.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the designed cross slide structure, abutment mechanism, and deflection plate, the moving contact can be coaxial with the through hole, allowing the stationary contact to be coaxial with the moving contact even before the handcart is pushed in and the valve baffle is closed. This ensures that the coaxial positioning operation can be completed in one go, improving alignment efficiency. Furthermore, after the stationary and moving contacts are coaxial, the pressure component can be used to fix the stationary contact to the switchgear body during the movement of the transverse plate, locking the position of the stationary contact. This ensures that the stationary contact remains coaxial with the moving contact throughout the movement of the handcart towards the switchgear body, guaranteeing coaxiality and connection stability when the stationary and moving contacts abut. The designed interlocking and staggered structures ensure the stability of the deflection plate in its initial state. When the stationary contact is fixed, the deflection plate sequentially performs actions of separating from the moving contact and deflecting 90°, achieving clearance and preventing interference during the handcart's insertion into the switchgear body.

Detailed Implementation
[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.
[0020] Please see Figures 1-11 In this embodiment of the invention, a double-layer switchgear with rapid static contact adjustment includes: a switchgear body 1, a moving contact 5, a cross slide structure, a contact mechanism, a deflection plate 21, and a misalignment structure.
[0021] The switch cabinet body 1 is equipped with a handcart 2. Guide roller sets 4 are provided on both sides of the handcart 2. The guide roller sets 4 are adapted to the guide box 3 provided in the switch cabinet body 1. When the handcart 2 is pushed to move into the switch cabinet body 1, the guide box 3 guides the guide roller sets 4, thereby ensuring the stability of the handcart 2 during the movement into the switch cabinet body 1.
[0022] The moving contact 5 is disposed on the handcart 2, and the moving contact 5 is adapted to the stationary contact 6 disposed in the switch cabinet body 1. In this application, the handcart 2 is provided with two sets of moving contacts 5, which are fixedly connected to the handcart 2. Similarly, two sets of stationary contacts 6 are also disposed in the switch cabinet body 1. The two sets of stationary contacts 6 operate synchronously. In the attached drawings, only one set of moving contacts 5 and stationary contacts 6 are shown.
[0023] The cross slide structure is disposed on the inner wall of the switch cabinet body 1 and connected to the stationary contact 6. A support plate 10 is connected to the cross slide structure. The cross slide structure includes two sets of longitudinal guide members 9 symmetrically disposed in the switch cabinet body 1 and a horizontal guide member 8 that is horizontally disposed and can slide along the length direction of the longitudinal guide members 9. An electrical connection module 7 is slidably installed on the horizontal guide member 8. The electrical connection module 7 connects the stationary contact 6 and the support plate 10.
[0024] In use, when the through hole on the deflection plate 21 is aligned with the moving contact 5, the electrical connection module 7 can be moved by the support plate 10. During this process, under the guidance of the longitudinal guide 9 and the transverse guide 8, the electrical connection module 7 can make transverse, longitudinal and transverse and longitudinal composite movements in the vertical space, and drive the stationary contact 6 to move, so that when the moving contact 5 enters the through hole, the corresponding stationary contact 6 can keep coaxial with the moving contact 5, thereby improving the accuracy of the subsequent docking.
[0025] Furthermore, the connection between the electrical connection module 7 and the switch cabinet body 1 is achieved through the longitudinal guide 9 and the transverse guide 8, which enables better stability during the movement of the electrical connection module 7, and ensures that the support plate 10 remains perpendicular to the inner wall of the switch cabinet body 1 during movement.
[0026] Please see Figures 3-4 , Figures 6-8 , Figure 11The abutting mechanism is disposed on the support plate 10. The abutting mechanism includes a lateral moving component and a pressure applying component. The lateral moving component can drive the pressure applying component to move so that the stationary contact 6 is fixed relative to the switch cabinet body 1. The lateral moving component includes an electric telescopic rod 17 fixedly installed in the switch cabinet body 1. A lateral moving plate 13 is connected to the moving end of the electric telescopic rod 17. The lateral moving plate 13 is provided with a guide groove 1301 along its length direction. Multiple sets of guide wheels 12 rotatably installed on the support plate 10 can roll in the guide groove 1301, so that the directionality is more obvious during the movement of the lateral moving plate 13 and the accuracy of its movement is improved.
[0027] The lateral movement assembly further includes an inclined surface 1302 disposed at the end of the lateral movement plate 13; the support plate 10 is also provided with an inclined groove 1001, and a coaxial wheel set 11 is rolled in the inclined groove 1001. The coaxial wheel set 11 includes a first grooved wheel 1101, a second grooved wheel 1102 and an abutting wheel 1103 coaxially disposed. The first grooved wheel 1101 can roll in the inclined groove 1001, the abutting wheel 1103 abuts against the inclined surface 1302, and the second grooved wheel 1102 is connected to the pressure application assembly; a second cylindrical spring 24 is connected to the shaft of the first grooved wheel 1101, and one end of the second cylindrical spring 24 away from the first grooved wheel 1101 is connected to the support plate 10; when the inclined surface 1302 acts on the abutting wheel 1103, the first grooved wheel 1101 can move along the inclined groove 1001, so that the second grooved wheel 1102 drives the pressure application assembly to move.
[0028] In this embodiment, in the initial state, the second columnar spring 24 is in a stretched state. At this time, under the elastic force provided by the second columnar spring 24, the coaxial wheel assembly 11 is pulled and placed at the lower end of the inclined groove 1001. At this time, the pressure application component is in a released state. When the moving contact 5 is inserted into the through hole and the moving contact 5 is coaxial with the stationary contact 6, the electric telescopic rod 17 is activated. The transverse plate 13 connected to the activated end of the electric telescopic rod 17 can move along its length direction. When the inclined surface 1302 on the transverse plate 13 abuts against the abutting wheel 1103, it can drive the coaxial wheel assembly 11 to move along the inclined groove 1001. At this time, the second columnar spring 24 can be further stretched. At the same time, the coaxial wheel assembly 11 drives the pressure application component to switch from the released state to the fixed state, so that the electrical connection module 7 and the stationary contact 6 can be in a fixed state relative to the switch cabinet body 1, thereby locking the stationary contact 6.
[0029] When the coaxial wheel assembly 11 moves along the inclined groove 1001, the coaxial wheel assembly 11 will also move along the inclined surface 1302. When the coaxial wheel assembly 11 is pushed to the upper surface of the transverse plate 13, the coaxial wheel assembly 11 can be locked, so that even when the transverse plate 13 continues to move, the pressure application component can still remain fixed, thus ensuring the stability of the stationary contact 6 in the locked state.
[0030] Based on the above settings, firstly, the stationary contact 6 and the moving contact 5 can be aligned with the through hole before the trolley 2 enters the switch cabinet body 1, ensuring that the installer has a good working view and that the coaxial positioning operation can be completed in one go, thus improving the debugging speed. Secondly, after the stationary contact 6 and the moving contact 5 are coaxial, the stationary contact 6 and the switch cabinet body 1 can be fixed by the pressure component during the movement of the transverse plate 13, thereby locking the position of the stationary contact 6. As a result, the stationary contact 6 can always maintain the coaxial state with the moving contact 5 during the movement of the trolley 2 toward the switch cabinet body 1, ensuring the coaxiality and connection stability of the stationary contact 6 and the moving contact 5 when they come into contact.
[0031] The pressure-applying assembly includes a limiting sleeve 16 fixedly mounted on the support plate 10 and a connecting frame 14 slidably mounted on the limiting sleeve 16. One end of the connecting frame 14 is provided with a vertical groove 1401, and the second grooved wheel 1102 can roll within the vertical groove 1401. The pressure-applying assembly also includes an abutment portion 15 provided at the other end of the connecting frame 14, the abutment portion 15 abutting and adapting to a damping plate 25 installed in the switch cabinet body 1. The connecting frame 14 is located along... A limiting groove 1402 is provided along its length, and a limiting block 1601 is provided on the inner wall of the limiting sleeve 16. The limiting groove 1402 and the limiting block 1601 cooperate to keep the limiting sleeve 16 and the connecting frame 14 axially locked. This axial locking setting prevents the connecting frame 14 from rotating relative to the limiting sleeve 16 during its movement, thereby ensuring the smooth movement of the second grooved wheel 1102 in the vertical groove 1401 and preventing jamming.
[0032] When the coaxial wheel assembly 11 moves within the inclined groove 1001, the second grooved wheel 1102 can cooperate with the vertical groove 1401 to drive the connecting frame 14 toward the damping plate 25. Specifically, during the movement of the coaxial wheel assembly 11 along the inclined groove 1001, it generates lateral and longitudinal movements. For longitudinal movement, the second grooved wheel 1102 can move upward within the vertical groove 1401. For lateral movement, the connecting frame 14 can drive the abutment part 15 toward the damping plate 25. When the abutment part 15 abuts against the damping plate 25, the abutment wheel 1103 just moves to the upper surface of the transverse plate 13, thereby locking the position of the connecting frame 14 and ensuring the stability of the abutment part 15 in the abutment state with the damping plate 25, thus ensuring the positional stability of the stationary contact 6.
[0033] Please see Figures 3-4 , Figures 6-7 , Figures 9-10 The deflecting plate 21 is slidably sleeved on the horizontal rod 22 mounted on the support plate 10. The deflecting plate 21 has a through hole adapted to the moving contact 5, and the deflecting plate 21 and the horizontal rod 22 are connected by a fitting structure. When the deflecting plate 21 moves along the horizontal rod 22, the fitting structure allows the deflecting plate 21 to rotate 90°. A tapered guide surface 2101 is provided on the side of the through hole facing the moving contact 5, which guides the moving contact 5 into the through hole. The structure includes a straight groove 2201 and a spiral groove 2202 arranged along the axial direction of the transverse rod 22, the straight groove 2201 and the spiral groove 2202 are connected; the fitting structure also includes a convex shaft 2102 arranged inside the rotating shaft of the deflection plate 21, the convex shaft 2102 can slide in the straight groove 2201 and the spiral groove 2202; a first cylindrical spring 23 is also sleeved inside the transverse rod 22, one end of the first cylindrical spring 23 is connected to the end of the transverse rod 22, and the other end is connected to the deflection plate 21.
[0034] In the initial state, the deflector plate 21 is located at the end of the transverse rod 22 away from the spiral groove 2202, and the convex shaft 2102 is located at the end of the straight groove 2201 away from the spiral groove 2202. The deflector plate 21 is axially locked relative to the transverse rod 22, ensuring the accuracy of the coaxiality between the stationary contact 6 and the moving contact 5 when the through hole and the moving contact 5 are coaxial. When the abutting part 15 and the damping plate 25 are in abutting state, locking the position of the stationary contact 6, the electric telescopic rod 17 will continue to move, driving the deflector plate 21 along the length direction of the transverse rod 22. During this process, the convex shaft 2102 first moves along the straight groove 2201, allowing the through hole on the deflection plate 21 to separate from the moving contact 5. Then, when the convex shaft 2102 switches from the straight groove 2201 to the spiral groove 2202, the deflection plate 21 will rotate. When the deflection plate 21 rotates 90°, the convex shaft 2102 moves to the end of the spiral groove 2202 away from the straight groove 2201, so that the deflection plate 21 completes the action of giving way, preventing the movement of the handcart 2 from being obstructed due to the presence of the deflection plate 21 during the process of pushing the handcart 2 toward the switch cabinet body 1.
[0035] The misaligned structure connects the transverse component and the deflection plate 21. When the stationary contact 6 is fixed relative to the switch cabinet body 1, the misaligned structure can drive the deflection plate 21 to move along the length direction of the transverse rod 22. The misaligned structure includes a sliding connection part 20 that is rotatably connected to the shaft of the transverse rod 22. The sliding connection part 20 can slide along the length direction of the support plate 10, and the sliding connection part 20 is provided with a hysteresis sleeve 19 that can be slidably connected to the operating end of the electric telescopic rod 17. The misaligned structure also includes a protruding ring 18 provided at the operating end of the electric telescopic rod 17, and the protruding ring 18 abuts and is adapted to the hysteresis sleeve 19.
[0036] During the process of the transverse plate 13 moving from its initial position to the point where the abutting wheel 1103 is above the transverse plate 13, the abutting part 15 can move toward the damping plate 25 and finally fit tightly against the damping plate 25, thus locking the stationary contact 6. During this process, the actuating end of the electric telescopic rod 17 only drives the transverse plate 13 to move. The sliding connection part 20 can maintain its original state due to the support of the first columnar spring 23. The hysteresis sleeve 19 can slide relative to the actuating end of the electric telescopic rod 17. When the abutting part 15 abuts against the damping plate 25 and locks the stationary contact 6, the abutting wheel 1103 is on the upper surface of the transverse plate 13. At this time, the convex ring 18 of the actuating end of the electric telescopic rod 17 just abuts against the side of the hysteresis sleeve 19, so that during the movement of the electric telescopic rod 17, the deflecting plate 21 can move along the length direction of the transverse rod 22 and complete the action of first separating from the moving contact 5 and then deflecting and repositioning.
[0037] Furthermore, during the movement of the sliding connection 20 and the deflection plate 21 caused by the side contact between the convex ring 18 and the hysteresis sleeve 19, the abutting wheel 1103 is always on the upper surface of the transverse plate 13, and the stationary contact 6 is always in a locked state.
[0038] As an embodiment of the present invention, an adjustment method for a double-layer switchgear with rapid static contact adjustment as described above is also proposed, comprising the following steps: Step 1: Move the handcart 2 to the front of the switch cabinet body 1 using the external support device. Push the external support device to allow the handcart 2 to enter the switch cabinet body 1. During this process, align the through hole on the deflection plate 21 with the moving contact 5. At this time, the stationary contact 6 will follow the movement of the deflection plate 21 until the moving contact 5 is inserted into the through hole, at which point the moving contact 5 and the stationary contact 6 are coaxial. Step 2: The movement of the lateral component drives the movement of the pressure application component, so that the stationary contact 6 is fixed relative to the switch cabinet body 1; Step 3: The lateral movement component continues to operate, causing the deflection plate 21 to first separate from the moving contact 5, and then deflect 90°. At this time, the deflection plate 21 can be misaligned with the handcart 2. Step 4: Push the handcart 2 toward the inside of the switch cabinet body 1 until the moving contact 5 and the stationary contact 6 engage, locking the handcart 2.

9. A method for adjusting a double-layer switchgear with rapid static contact adjustment as described in any one of claims 1 to 8, characterized in that, Includes the following steps: Step 1: Move the handcart to the front of the switchgear body using the external support device. As the handcart enters the switchgear body by pushing the external support device, align the through hole on the deflection plate with the moving contact. At this time, the stationary contact will follow the movement of the deflection plate until the moving contact is inserted into the through hole, at which point the moving contact and the stationary contact are coaxial. Step 2: The movement of the lateral component drives the movement of the pressure application component to fix the stationary contact relative to the switch cabinet body; Step 3: The lateral movement component continues to operate, causing the deflection plate to first separate from the moving contact, and then deflect 90°. At this point, the deflection plate can be misaligned with the handcart. Step 4: Push the handcart toward the inside of the switch cabinet body until the moving contact and stationary contact engage, thus locking the handcart.
