Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment, and in particular to a grounding switch with a spring mechanism. Background Art

[0002] The grounding switch is a kind of power switch configured on the line side of the power transmission and transformation outgoing line loop. It has the ability to open and close the capacitive current generated by electrostatic induction and the inductive current generated by electromagnetic induction of the overhead line, as well as the ability to close the fault current. At present, some actions of the grounding switch, such as closing and opening, are mostly performed by an electric spring mechanism. The electric spring mechanism stores energy in the spring through the motor, and the spring releases the stored energy when the mechanism needs to move to realize the action of the driving mechanism. However, in the current electric spring operating mechanism, the action of the motor on the spring is mostly through the rotation of the worm and worm gear, and then drives the crank arm to rotate to compress the spring to store energy. Similarly, when the spring energy is released, it also requires a connecting rod system to realize the opening and closing operation of the grounding switch; the action of the above-mentioned motor on the spring and the action of the spring on the grounding switch require a long transmission system, which is complex in structure and difficult to stabilize the performance, resulting in the need to complete the closing from the beginning to the completion of the closing in seconds, affecting the response speed of the equipment.

[0003] Therefore, how to reduce the structural complexity of the grounding switch and its actuating mechanism and improve its operational stability is a technical problem that needs to be urgently solved by those skilled in the art. Summary of the invention

[0008] A driving motor, which is externally arranged on the frame and drivingly connected to the lower baffle;

[0009] A motion shaft, insulated and connected to the action end of the switch portion;

[0010] The lower baffle moves toward the fixed plate to further compress the first spring and the second spring, and allows the grounding switch to store energy when moving to the first position.

[0012] Preferably, in the above-mentioned grounding switch with spring mechanism, it also includes a closing state. When the grounding switch is in the closing state, the lower baffle is limited to the first position by the opening latch, the first spring remains compressed and stores energy, the second spring releases energy and drives the upper baffle away from the lower baffle, the moving shaft moves to a third position, and the third position is a position closer to the actuating end than the second position; the actuating end is in an extended state.

[0013] Preferably, in the above-mentioned grounding switch with a spring mechanism, the moving shaft is limited and locked by a balancing latch when in the third position.

[0014] Preferably, in the above-mentioned grounding switch with spring mechanism, it also includes an open state. When the grounding switch is in the open state, the first spring releases energy and drives the lower baffle plate away from the fixed plate, the moving shaft moves to the second position and is limited and locked by the closing latch, and the action end is in a retracted state.

[0015] Preferably, in the above-mentioned grounding switch with a spring mechanism, first spring washers are provided in areas on the balancing latch and the closing latch for limiting the movement axis.

[0016] Preferably, in the above-mentioned grounding switch with a spring mechanism, the moving shaft and the action end are connected to form an integral structure via an insulating plate, and the insulating plate and the moving shaft are connected via bolts.

[0017] Preferably, in the above-mentioned grounding switch with a spring mechanism, the distance between the balancing latch and the closing latch in the moving direction of the moving shaft is a preset breaking distance.

[0018] Preferably, in the above-mentioned grounding switch with spring mechanism, at least three balancing latches are evenly arranged in the circumferential direction of the moving axis, and the closing latch and the opening latch are arranged in the same manner; at least three second springs are evenly arranged in the circumferential direction of the moving axis.

[0023] It can be seen from the above technical solution that the grounding switch with a spring mechanism provided by the present invention integrates the switch part at one end of the frame, and the drive motor for spring energy storage is arranged outside the frame, so as to reduce the number of structural components arranged on the frame and reduce the volume of the frame; the shaft seal between the switch part and the frame can make the moving shaft pass through the contact plane between the switch part and the frame, and smoothly realize the connection drive of the action end in the switch part. The driving motor is connected to the lower baffle plate arranged on the frame in a transmission manner so as to drive the lower baffle plate to move toward the fixed plate, thereby cooperating with the fixed plate and the upper baffle plate to realize compression energy storage of the first spring and the second spring. The energy storage process is realized by a single lower baffle plate, which can improve the degree of integration of components on the frame, thereby reducing the volume and complexity of the grounding switch. At the same time, the energy storage process is a further compression of the first spring and the second spring, that is, the lower baffle plate moves toward the fixed plate to realize spring energy storage, and there is no idle stroke, which not only accelerates the energy storage process, but also the lower baffle plate has a greater compression amount of the first spring and the second spring when the same stroke as the prior art is achieved, and can achieve a faster response speed through stronger elastic potential energy in the subsequent process of the grounding switch requiring the spring to release energy for state switching.

DETAILED DESCRIPTION

[0031] The core of the present invention is to disclose a grounding switch with a spring mechanism to reduce the structural complexity of the grounding switch and its actuating mechanism.

[0032] In order to make the technical personnel in this field better understand the scheme of the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the content of the invention recorded in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary for the solutions of the invention recorded in the claims.

[0033] like Figure 1 As shown, the grounding switch with spring mechanism provided by the embodiment of the present invention mainly includes a switch part 10 and a frame 20, wherein the switch part 10 is the action execution end of the grounding switch, and an action end 110 is arranged inside the switch part 10, so as to generate a position through the telescopic movement of the action end 110, thereby realizing the operation state adjustment of the grounding switch. The frame 20 is used as the main bearing structure, and the switch part 10 is fixedly arranged at one end of the frame 20 to form an integrated structure with the frame 20, and a shaft seal is arranged between the switch part 10 and the frame 20, and the shaft seal can keep the switch part 10 and the frame 20 in a connected state to realize power transmission, while independently separating the switch part 10 from the adjustment part on the frame 20 to maintain the stability of the movement of the two areas.

[0034] The frame 20 is a bearing structure, on which a fixing plate 210 is fixedly arranged. The fixing plate 210 is a reference structure of the adjusting part on the frame 20. At the same time, an upper baffle 220 and a lower baffle 230 are respectively arranged at intervals on both sides of the fixing plate 210 in the first direction. It should be noted here that the first direction is the direction in which the adjusting part on the frame 20 drives the action end 110 of the switch part 10 to move, which is preferably perpendicular to the direction of the fixing plate 210. On this basis, the fixing plate 210 and the lower baffle 230 are connected in a floating manner through the first spring 240, and the upper baffle 220 and the lower baffle 230 are connected in a floating manner through the second spring 250.

[0035] In particular, the grounding switch with spring mechanism provided in the embodiment of the present invention is also provided with a driving motor 30 to charge the first spring 240 and the second spring 250. The driving motor 30 is externally arranged on the frame 20 and is connected to the lower baffle 230 through a transmission structure. The externally arranged driving motor 30 can reduce the difficulty of the structural arrangement of the frame 20, and it will not occupy the arrangement of the components on the frame 20. At the same time, it can drive the lower baffle 230 so that the lower baffle 230 moves toward the fixed plate 210 to compress the first spring 240 and the second spring 250, thereby completing the charging process of the first spring 240 and the second spring 250. In order to meet the movement of the action end 110 on the switch part 10, a motion shaft 40 insulated from the action end 110 is also provided on the frame 20, so that the movement of the action end 110 is realized through the movement of the motion shaft 40, thereby changing the working state of the grounding switch.

[0036] On the basis of the above structure, the driving motor 30 can at least drive the lower baffle 230 to move toward the fixed plate 210, and the lower baffle 230 can further compress the first spring 240 and the second spring 250 in the process of moving toward the fixed plate 210, and at the same time, the lower baffle 230 makes the grounding switch store energy when it moves to the first position; it should be noted that the further compression of the lower baffle 230 here specifically refers to the first spring 240 and the second spring 250 being in a compressed state in the absence of external force, and the energy storage process is to further compress the first spring 240 and the second spring 250 in a compressed state to meet the potential energy accumulation requirements of the spring, which can store energy for the first spring 240 and the second spring 250 when the lower baffle 230 starts to move, so that there is no idle part in the energy storage stage, and the kinetic energy applied by the driving motor 30 is used as much as possible, and at the same time, the spring can accumulate more potential energy under the same stroke, and can also accelerate the closing action in the subsequent action process. In the above structure, Figure 2As shown, when the grounding switch is in the energy storage state, the lower baffle 230 is locked in the first position by the limiting structure, and cooperates with the fixed plate 210 to maintain the compressed energy storage state of the first spring 240; and the upper baffle 220 first moves to the position abutting the moving shaft 40 under the pushing action of the second spring 250, and the moving shaft 40 is limited and locked in the second position, and the upper baffle 220 is limited to maintain the compressed state of the second spring 250, and it should be noted that at this time, the moving shaft 40 is limited and locked in the second position, and no thrust is applied to the action end 110 of the switch part 10, that is, the grounding switch is only in the energy storage state.

[0037] In the grounding switch with a spring mechanism provided in an embodiment of the present invention, the switch part 10 is integrated at one end of the frame 20, and the drive motor 30 for spring energy storage is externally arranged on the frame 20, so as to reduce the number of structural components arranged on the frame 20 and reduce the volume of the frame 20; the shaft seal between the switch part 10 and the frame 20 enables the moving shaft 40 to pass through the contact plane between the switch part 10 and the frame 20, and smoothly realizes the connection drive of the action end 110 in the switch part 10. The driving motor 30 is transmission-connected to the lower baffle plate 230 provided on the frame 20 so as to be able to drive the lower baffle plate 230 to move toward the fixed plate 210, thereby cooperating with the fixed plate 210 and the upper baffle plate 220 to realize the compression energy storage of the first spring 240 and the second spring 250. The energy storage process is realized by a single lower baffle plate 230, which can improve the degree of integration of components on the frame 20, thereby reducing the volume and complexity of the grounding switch. At the same time, the energy storage process is a further compression of the first spring 240 and the second spring 250, that is, the lower baffle plate 230 moves toward the fixed plate 210 to realize spring energy storage, and there is no idle stroke, which not only accelerates the energy storage process, but also the lower baffle plate 230 has a greater compression amount of the first spring 240 and the second spring 250 when the same stroke is achieved as the prior art, and can achieve a faster response speed through stronger elastic potential energy in the subsequent process of the grounding switch requiring the spring to release energy for state switching.

[0038] On the basis of the above embodiments, in combination with the commonly used component structures of the grounding switch, in some embodiments of the present invention, a disconnect latch 510 and a closing latch 520 are further provided on the frame 20. Specifically, when the grounding switch is in the energy storage state, the lower baffle 230 is limited and locked by the disconnect latch 510 in the first position, so that the lower baffle 230 maintains a stable position, that is, the lower baffle 230 maintains a fixed distance from the fixed plate 210, and the first spring 240 is in a stable compressed energy storage state; at the same time, the moving shaft 40 is limited and locked by the closing latch 520 in the second position, so that the moving shaft 40 blocks the upper baffle 220 in the second position, so that the upper baffle 220 and the lower baffle 230 bracket maintain a fixed distance, and the second spring 250 is in a stable compressed energy storage state. The structures and actions of the opening latch 510 and the closing latch 520 are the same as those of the commonly used grounding switches, and for the limit locking of the lower baffle 230 in the first position, the opening latch 510 can be achieved by abutting against a side plate structure of the lower baffle 230; for the limit locking of the moving shaft 40 in the second position, the closing latch 520 can be embedded in the side wall of the moving shaft 40, or a component with an integrated structure extending from the moving shaft 40, for the closing latch 520 to abut against and achieve limit.

[0039] Further, based on the above-mentioned grounding switch capable of realizing the energy storage state, and in combination with the use requirements of the grounding switch, the grounding switch with a spring mechanism provided in the embodiment of the present invention also includes a closing state. It should be noted that the closing state is a state in which the grounding switch is started and executed when the closing state is required after the grounding switch is in the energy storage state. Specifically, Figure 3 As shown, when the closing state needs to be switched, first, the lower baffle plate 230 is still stably located in the first position under the action of the opening latch 510, the first spring 240 remains in a compressed state, and the lower baffle plate 230 provides a support basis for the energy release of the second spring 250; secondly, the closing latch 520 releases the moving shaft 40, and the moving shaft 40 loses its limiting locking effect on the upper baffle plate 220, and the end of the second spring 250 connected to the lower baffle plate 230 remains in a fixed position, while the end connected to the upper baffle plate 220 will push the upper baffle plate 220 and act on the moving shaft 40 when the elastic potential energy of the second spring 250 is released. 40 leaves the second position and moves in the direction away from the fixed plate 210, thereby pushing the action end 110 to move; and it should be noted that the design of the second spring 250 must meet the requirement that after the closing latch 520 releases the moving shaft 40, it can push the moving shaft 40 to move to the third position, and the third position is a position closer to the action end 110 than the second position. When the moving shaft 40 moves to the third position, the action end 110 will follow the displacement and switch to the extended state. The change in the position of the action end 110 can realize the change in the operating state of the grounding switch, so that the grounding switch switches from the energy storage state to the closing state to meet the use.

[0040] It should be noted that in the process of switching the grounding switch from the energy storage state to the closed state, it is only necessary to operate the closing latch 520 to release the moving shaft 40, and the switching can be completed through the automatic action of the second spring 250. The operation is convenient and quick. At the same time, in the aforementioned embodiment, the second spring 250 has a stronger elastic potential energy accumulation, and can realize the switching of the closed state of the grounding switch faster than the prior art, thereby improving the response speed of the equipment.

[0041] In order to further optimize the above technical solution, the embodiment of the present invention further provides a balancing latch 530 on the frame 20. The balancing latch 530 is used to limit and lock the moving shaft 40 when the moving shaft 40 moves to the third position, so that the position of the moving shaft 40 is fixed, and the action end 110 is kept in a stable extended state. The balancing latch 530 can adopt the same structure as the closing latch 520, and is arranged at intervals in the first direction, so as to meet the purpose of limiting and locking the moving shaft 40 at the third position and the second position respectively.

[0042] Furthermore, the grounding switch provided in the embodiment of the present invention also includes an opening state, and it should be noted that the opening state is an operation state after the closing state in the above embodiment, so the opening state is mostly described based on the states of the various components in the closing state. Specifically, Figure 4 As shown, when the grounding switch needs to be switched from the closed state to the open state, the second spring 250 has released its energy, and the moving shaft 40 is limited and locked in the third position by the balancing latch 530. Therefore, the opening latch 510 and the balancing latch 530 in the grounding switch are actuated to release the lower baffle 230 and the moving shaft 40 respectively. At this time, the end of the first spring 240 connected to the fixed plate 210 remains in a fixed position, while the end connected to the lower baffle 230 is able to move in the first spring 240 because the lower baffle 230 is unlocked. The released potential energy pushes the lower baffle 230 to move in the direction away from the fixed plate 210. At the same time, the displacement of the lower baffle 230 acts on the moving shaft 40, driving the moving shaft 40 to switch back from the third position to the second position, and the moving shaft 40 is limited and locked to the second position by the closing latch 520. Similarly, since the moving shaft 40 moves to the second position, the action end 110 will be driven and is in a retracted state, the grounding switch is in an open state, and waits for the subsequent drive motor 30 to realize the next energy storage process.

[0043] Furthermore, since the areas on the balancing latch 530 and the closing latch 520 used to limit and lock the moving shaft 40 are mostly in rigid contact with the moving shaft 40, in order to reduce the damage to the moving shaft 40 caused by the rigid contact, it is preferred that the areas on the balancing latch 530 and the closing latch 520 for limiting the moving shaft 40 are both provided with a first spring gasket 610 to reduce the damage to the moving shaft 40 during the limiting process.

[0044] In addition, in some embodiments of the present invention, the moving shaft 40 and the action end 110 are connected as an integrated structure through the insulating plate 410, so as to achieve effective driving of the action end 110 by the moving shaft 40 while maintaining the independent movement of the switch part 10 and the bracket. It should be noted that the insulating plate 410 and the moving shaft 40 are connected by bolts to maintain a stable connection and meet the disassembly and assembly requirements.

[0045] Further, in the above embodiment, when the grounding switch switches from the energy storage state to the closing state, and from the closing state to the opening state, the effective movement distance of the motion shaft 40 is the distance between the second position and the third position. In order to reduce the structural complexity of the grounding switch, it is preferred that the movement of the motion shaft 40 between the second position and the third position is a linear movement, and the balancing latch 530 and the closing latch 520 are arranged on the same straight line in the movement direction of the motion shaft 40, which not only simplifies the running path of the motion shaft 40, but also simplifies the arrangement of the balancing latch 530 and the closing latch 520 and the limiting of the motion shaft 40. At this time, the distance between the balancing latch 530 and the closing latch 520 in the movement direction of the motion shaft 40 is the preset disconnection distance, that is, the effective distance that the action end 110 meets to extend to realize the state switching of the grounding switch, and it should be noted that the preset disconnection distance can be adjusted as needed by adjusting the position of at least one of the balancing latch 530 and the closing latch 520.

[0046] In order to improve the stability of the moving shaft 40 during the grounding switch operation, as Figure 1 and Figure 5As shown, preferably, at least three balancing latches 530 are evenly arranged in the circumferential direction of the moving shaft 40, so that when the moving shaft 40 is in the third position, the limiting effect is evenly applied from three directions in the circumferential direction of the moving shaft 40, and the stable state of the moving shaft 40 is maintained. At least three balancing latches 530 can serve as backup for each other, reduce the risk of slipping of the moving shaft 40, and improve the operating stability of the grounding switch. It should be noted that the closing latch 520 and the opening latch 510 are preferably arranged in the same structural form, that is, at least three closing latches 520 and opening latches 510 are evenly arranged in the circumferential direction of the moving shaft 40 to achieve a stable limiting effect of the moving shaft 40, that is, the lower baffle 230. At the same time, in the direction parallel to the moving shaft 40, the balancing latch 530, the closing latch 520 and the opening latch 510 can be arranged on the same straight line to improve the uniformity of the frame 20 structure and the convenience of setting the limiting structure.

[0047] Furthermore, in some embodiments of the present invention, the upper baffle plate 220 and the lower baffle plate 230 are both slidably sleeved on the outer periphery of the moving shaft 40 so as to be able to slide relative to the moving shaft 40 to realize energy storage and driving actions. At the same time, the moving shaft 40 is preferably arranged through the center of the upper baffle plate 220 and the lower baffle plate 230, so that the upper baffle plate 220 and the lower baffle plate 230 can be more uniform when applying force to the moving shaft 40. At the same time, the spring and the limiting structure are easy to set, such as the second spring 250, which can be evenly arranged in the circumferential direction of the moving shaft 40. The moving shaft 40 is arranged through the center of the upper baffle plate 220 and the lower baffle plate 230, and the second spring 250 used to connect the upper baffle plate 220 and the lower baffle plate 230 can be arranged around the central axis, which improves the stability of the connection between the upper baffle plate 220 and the lower baffle plate 230. During the energy storage and energy release process of the second spring 250, the baffle is subjected to uniform force and can realize stable moving action.

[0048] It should be noted that, based on the above-mentioned embodiment, the moving shaft 40 can be set to an axis structure with a variable cross-section in the first direction, and the cross-sectional area of ​​the area used to sleeve the upper baffle 220 and the lower baffle 230 and for the upper baffle 220 and the lower baffle 230 to slide is relatively small. Based on this, when the grounding switch is switched to the open state, the lower baffle 230 can be abutted against the moving shaft 40 through the variable cross-section of the moving shaft 40, and drive the moving shaft 40 to move. The moving shaft 40 does not need to be provided with other limiting structures, thereby reducing the structural complexity of the moving shaft 40.

[0049] In addition, in order to improve the convenience of driving the moving shaft 40, in some embodiments of the present invention, a moving plate 420 is fixedly provided on the moving shaft 40. When the grounding switch is in the energy storage state, the upper baffle 220 is attached to and abuts against the moving plate 420. At this time, the force between the upper baffle 220 and the moving shaft 40 is applied through the moving plate 420, and the surface-to-surface contact structure can achieve more uniform force transmission. At the same time, in the process of limiting and locking the moving shaft 40 by the closing latch 520 and the balancing latch 530, the closing latch 520 and the balancing latch 530 only need to clamp or abut the moving plate 420 from the edge of the moving plate 420 to meet the locking of the moving shaft 40, which reduces the structural design difficulty of the closing latch 520 and the balancing latch 530 and improves the convenience of limiting the moving shaft 40.

[0050] On the basis of the above embodiment, a second spring washer 620 is provided on the side of the moving plate 420 facing the upper baffle 220. When the upper baffle 220 stores energy in the second spring 250 and abuts against the moving plate 420, it can achieve flexible contact with the second spring washer 620 to avoid damage caused by a direct rigid collision with the upper baffle 220. It should also be noted that in the grounding switch with a spring mechanism provided in the embodiment of the present invention, a spring washer can be provided between any two components that may cause a rigid collision to avoid damage to the components by the rigid collision, which will not be described in detail herein.

[0051] Furthermore, in the grounding switch with a spring mechanism provided in an embodiment of the present invention, the driving motor 30 is transmission-connected to the lower baffle 230 via a crank-connecting rod mechanism 310. The crank-connecting rod mechanism 310 can not only realize the driving of the lower baffle 230 arranged in the frame 20 by the driving motor 30 external to the frame 20 through its own structure, but also the crank-connecting rod mechanism 310 can continue to move after the driving motor 30 drives the lower baffle 230 to move to the first position, and reset after completing one circle, and wait for the subsequent energy storage process.
