Description

Technical Field

[0001] The present invention relates to the field of transformers, and in particular to an energy storage box-type transformer and a high-voltage switch structure thereof. Background Art

[0002] Chinese patent publication number CN207938519U discloses a high-voltage vacuum load switch-fuse combination device, comprising a frame on which a fuse is mounted. To install the fuse in this patent, the user first holds the fuse upright, then places it vertically onto a copper plate, and then connects the connector to the fuse to complete the installation.

[0003] The fuses of the above-mentioned equipment are installed by vertical plug-in. Since the fuses are cylindrical and have a smooth surface, it is difficult for technicians to hold the fuses firmly during vertical installation, which increases the construction difficulties for technicians. Therefore, the installation and removal of the fuses of the above-mentioned equipment are relatively difficult. Summary of the Invention

[0004] The present application provides an energy storage box-type transformer and a high-voltage switch structure thereof, which realizes rapid disassembly and assembly of fuses by means of lateral plugging and rotation, and has the characteristics of simple operation, labor saving and high efficiency.

[0005] The present application provides a high-voltage switch structure that adopts the following technical solution:

[0006] The cam is mounted on the support frame, and the cam is mounted on the support frame, wherein the cam is mounted on the support frame, ...

[0007] By adopting the above technical solution, when installing the fuse, the staff grasps the upper end of the fuse with one hand and supports the fuse with the other hand, holding the fuse horizontally. This method can hold the fuse more firmly. Then insert the lower end of the fuse into the slot, then release the hand holding the fuse, and push the fuse up with the hand holding the upper end of the fuse, so that the fuse rotates with the turntable, and finally the fuse presses the turntable against the mounting base. The technician then cancels the grip on the upper end of the fuse and supports the fuse, so that the fuse is in a vertical installation state. Then the driving mechanism drives the fixed cover downward so that the fixed cover is installed and presses the upper end of the fuse to complete the installation and fixation of the fuse. When removing the fuse, the technician first holds the fuse, and then the driving mechanism drives the fixed cover to move upward so that the fixed cover cancels the fixation of the upper end of the fuse. Then the technician grasps the upper end of the fuse and forces the fuse to tilt so that the fuse tilts toward the technician's body. When the fuse tilts, the first spring will also assist in the tilting of the fuse by driving the turntable to rotate. After the fuse is turned sideways, the lower end of the fuse can be pulled out of the slot. Compared with the vertical plug-in installation method, the installation method of this application is more labor-saving and convenient.

[0008] Preferably, the driving mechanism includes a second spring provided on the mounting head, a push rod connected to the equipment platform for sliding along the X-axis direction, and a handle fixed on the push rod; the second spring is in conflict with the fixed cover, and the second spring always drives the fixed cover to move toward the mounting seat; the push rod is in conflict with the fixed cover, and the push rod is located on the side of the fixed cover close to the equipment platform, and when the push rod moves away from the equipment platform, it drives the fixed cover to move away from the mounting seat.

[0009] By adopting the above technical solution, before installing the fuse, in addition to the technician holding the fuse horizontally, another technician pushes the handle to move the push rod away from the equipment platform. When the push rod moves away from the equipment platform, it pushes the fixed cover to move upward and causes the second spring to be compressed. After the fixed cover moves to a certain height, the technician holding the fuse horizontally inserts the lower end of the fuse into the fuse slot and vertically installs the fuse. Then the technician holding the handle releases the handle, the second spring will rebound and drive the fixed cover to move downward and finally the second spring will press the fixed cover onto the upper end of the fuse, completing the installation of the fuse.

[0010] Preferably, the mounting seat is connected to a limit plate which slides along the Z-axis direction, and the limit plate is used to cooperate with the handle to limit the movement of the push rod toward the equipment platform. The mounting seat is also provided with a first control mechanism for controlling the sliding of the limit plate. In the initial state, the limit plate is located at the highest point and contacts the handle to limit the movement of the push rod close to the equipment platform. At this time, the push rod is located at the position where its movement path is farthest from the equipment platform, and the push rod lifts the fixed cover so that the fixed cover is located at the highest point.

[0011] With this technical solution, after the fuse is inserted into the slot and vertically aligned, the first control mechanism controls the limit plate to move downward, ultimately disengaging it from the handle. Without the limit plate's restraint, the second spring drives the retaining cover downward, ultimately pressing it against the upper end of the fuse, securing the fuse.

[0012] Preferably, the first control mechanism includes a slide groove provided on the mounting seat, a guide rod provided in the slide groove, and a top plate connected to the guide rod for sliding along the Z-axis direction, the limit plate is installed on the top plate, and the turntable rests on the top plate; the first spring is sleeved on the guide rod, the top plate is located between the turntable and the first spring, one end of the first spring is in conflict with the bottom wall of the slide groove, and the other end of the first spring is in conflict with the top plate, and the first spring always drives the top plate to move toward the fixed cover; in the initial state, the first spring pushes the top plate out of the slide groove so that the top plate lifts the turntable to put the turntable in a flipping state; when the turntable is pressed by the fuse, the top plate and the limit plate will slide into the slide groove, and when the turntable moves to conflict with the mounting seat, the limit plate moves to disengage from the handle.

[0013] By adopting the above technical solution, after the fuse is inserted into the slot and upright, the limit plate moves downward and just moves to disengage from the handle. Then, under the action of the second spring, the fixed cover moves downward and presses and fixes the upper end of the fuse. This arrangement allows one person to complete the installation of the fuse. When an old fuse needs to be replaced, the technician first holds the fuse column with one hand, and then uses the other hand to pull the handle to move the push rod away from the equipment platform. The push rod moves away from the equipment platform and pushes the fixed cover upward, canceling the fixed cover's fixation on the fuse. The technician then slowly moves the hand holding the fuse upward until finally grasping the upper end of the fuse, and then applies force to the fuse to rotate the turntable. After the fuse rotates out of the movement path of the fixed cover, the technician's hand holding the handle can cancel its grip on the handle, and together with the other hand, the fuse is supported, allowing the fuse to slowly tilt, making it easier to pull the fuse out of the slot. After removing the fuse from the slot, the technician first presses the turntable against the mounting base. Then, the technician pulls the handle and push rod back to their initial positions. After removing the footsteps on the turntable, the first spring rebounds, causing the limit plate to move up and back against the handle, securing the handle and facilitating the installation of a new fuse. This structure allows one person to easily complete fuse removal and replacement.

[0014] Preferably, a pressing tongue is hinged on the mounting head, and a second control mechanism is provided on the push rod, and the second control mechanism is used to drive the pressing tongue to rotate so that the pressing tongue presses against the upper end of the fuse.

[0015] By adopting the above technical solution, when removing an old fuse, the second control mechanism is used to rotate the detent to press against the upper end of the fuse. After the fixed cover moves away from the upper end of the fuse, the technician can grasp the upper end of the fuse with his hand. The above structure can assist the technician in holding the fuse when removing the old fuse, preventing the technician from losing a firm grip on the fuse and causing it to fall due to gravity.

[0016] Preferably, the second control mechanism includes an active cavity and a limiting cavity which are opened on the top rod and are interconnected, and a roller body slidably arranged in the limiting cavity and the active cavity, the limiting cavity is located on the side of the active cavity away from the equipment platform, and the roller body is connected to the end of the pressing tongue away from the fixed cover; when the roller body is located in the active cavity, the pressing tongue can rotate around the hinge; when the roller body is located in the limiting cavity, the pressing tongue cannot rotate, and when the pressing tongue presses the upper end of the fuse, the roller body is located in the limiting cavity; in the initial state, the roller body is located in the active cavity.

[0017] By adopting the above technical solution, during the downward movement of the fixed cover, the push rod will move closer to the equipment platform. When the push rod moves closer to the equipment platform, the roller body will move from the movable cavity to the limit cavity. When the roller body moves into the limit cavity, the pressing tongue rotates and presses against the upper end of the fuse. At this time, the fixed cover has not yet moved to abut against the upper end of the fuse. At this time, the pressing tongue can assist the technician in holding the fuse. During the removal of the fuse, the technician will pull the handle and the push rod will move away from the equipment platform, causing the push rod to move upward against the fixed cover, while the roller body will move closer to the movable cavity. After the fixed cover completely moves away from the upper end of the fuse, the roller body is still located in the limit cavity, so the pressing tongue is still in a pressing state against the upper end of the fuse. At this time, it can assist the technician in holding the fuse, making it convenient for the technician to move the hand holding the fuse and grasp the upper end of the fuse.

[0018] The energy storage box-type transformer provided in this application adopts the following technical solution:

[0019] Preferably, the above-mentioned high-voltage switch structure is applied.

[0020] By adopting the above technical solution, the difficulty of disassembling and assembling the fuse in the transformer is reduced.

[0021] The technical effects of the present invention are mainly reflected in the following aspects:

[0022] 1. The present invention adopts the method of horizontal plugging and rotating to install the fuse to reduce the difficulty of fuse installation;

[0023] 2. The present invention achieves automatic fixing of the fuse through the cooperation of the second spring, the fixing cover and other components;

[0024] 3. The present invention provides a tongue depressor and a second control mechanism to assist in the installation and removal of the fuse. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention is further described in detail below with reference to the accompanying drawings to make the technical solution of this application easier to understand and grasp. Example 1:

[0037] Reference Figure 1 A high-voltage switch structure of this embodiment includes an equipment platform 1, on which an insulator 11 and a grounding switch 12 are provided. A fixing frame 13 is provided on the insulator 11, and the grounding switch 12 is connected to the fixing frame 13.

[0038] Reference Figure 1-Figure 3 The mounting head 14 is fixed on the equipment platform 1. A fixing cover 3 for pressing the upper end of the fuse 8 is slidably connected to the mounting head 14 along the Z-axis direction. Two rods 31 are integrally formed on the fixing cover 3. The two rods 31 are slidably connected to the mounting head 14 along with the fixing cover 3.

[0039] Reference Figure 1-Figure 3 Two limiting blocks 32 are integrally formed on each of the two rods 1 31 , with the two rods 1 31 positioned between the two limiting blocks 32. The mounting head 14 has two limiting slots 141 defined therein, with the two limiting blocks 32 slidingly connected within the two limiting slots 141 along the Z-axis. The two limiting blocks 32 cooperate with the two limiting slots 141 to prevent the fixed cover 3 and the two rods 1 31 from detaching from the mounting head 14. In this embodiment, damping pads can be provided within the two limiting slots 141 to control the movement speed of the limiting blocks 32, ultimately achieving the purpose of controlling the movement speed of the fixed cover 3.

[0040] Reference Figure 1-Figure 3 The equipment platform 1 is also provided with a driving mechanism 4 for driving the fixed cover 3 to move. The driving mechanism 4 includes two second springs 41, wherein the two second springs 41 are respectively mounted on the two rod bodies 31, and one end of the two second springs 41 is in conflict with the mounting head 14, and the other ends of the two second springs 41 are respectively in conflict with the two limit blocks on the fixed cover 3. The two second springs 41 are always in a state of force compression, and the second springs 41 always drive the fixed cover 3 to move toward the ground.

[0041] Reference Figure 1-Figure 3 The drive mechanism 4 also includes a push rod 42 that is slidably connected to the device platform 1 along the X-axis, and a handle 43 fixed to the push rod 42. The push rod 42 is located on the side of the fixed cover 3 that is close to the device platform 1. The end of the push rod 42 that is away from the device platform 1 contacts the fixed cover 3. The contacting surfaces of the push rod 42 and the fixed cover 3 are both inclined, facilitating force transmission. When the push rod 42 moves away from the device platform 1, it drives the fixed cover 3 to move away from the mounting base 2.

[0042] Reference Figure 1 and Figure 2A mounting base 2 is fixed on the fixing frame 13 and is located below the fixing cover 3. A limit plate 24 is slidably connected to the mounting base 2 along the Z-axis direction. The limit plate 24 is used to cooperate with the handle 43 to limit the movement of the push rod 42 toward the device platform 1.

[0043] Reference Figure 1 and Figure 4 The mounting base 2 is also provided with a first control mechanism 5 for controlling the sliding of the limit plate 24. The first control mechanism 5 includes a slide groove 51 opened on the mounting base 2, two guide rods 52 fixed in the slide groove 51, and a top plate 53 connected to the two guide rods 52 and sliding along the Z-axis direction. The limit plate 24 is fixed on.

[0044] Reference Figures 1-4 , wherein the two guide rods 52 are each sleeved with a first spring 23. One end of the two first springs 23 contacts the bottom wall of the chute 51, and the other end of the two first springs 23 contacts the top plate 53. The two first springs 23 always drive the top plate 53 to move toward the fixed cover 3. In the initial state, the two first springs 23 push the top plate 53 out of the chute 51. The top plate 53 and the limit plate 24 are at the highest point. The limit plate 24 contacts the handle 43. The limit plate 24 is located on the side of the handle 43 close to the equipment platform 1. The limit plate 24 restricts the movement of the handle 43 and the push rod 42 close to the equipment platform 1. At this time, the push rod 42 is at the position farthest away from the equipment platform 1 in its movement path. The push rod 42 lifts the fixed cover 3 so that the fixed cover 3 is at the highest point.

[0045] Reference Figure 1 and Figure 4 A turntable 21 is hingedly mounted on the mounting base 2, with its hinge axis parallel to the Y-axis. A slot 22 is provided on the turntable 21, which engages with the lower end of the fuse 8. When the lower end of the fuse 8 is inserted into the slot 22 and the fuse 8 presses the turntable 21 against the mounting base 2, the upper end of the fuse 8 is positioned below the fixed cover 3 and within the fixed cover's motion path.

[0046] Reference Figure 1 and Figure 4 The turntable 21 rests against the top plate 53, which is located between the turntable 21 and the two first springs 23. Initially, the two first springs 23 push the top plate 53 out of the chute 51, lifting the turntable 21 and placing it in a flipped position. When the turntable 21 is in the flipped position, the notch 22 of the locking slot 22 faces away from the equipment platform 1. When the turntable 21 is pressed by the fuse 8, the top plate 53 and the limit plate 24 slide into the chute 51. When the turntable 21 contacts the mounting base 2, the limit plate 24 moves away from the handle 43.

[0047] Reference Figure 1-Figure 3A detent 6 is hingedly mounted on the mounting head 14, with its hinge axis parallel to the Y-axis. Two sets of second control mechanisms 7 are also provided on the top rod 42, which are used to rotate the detent 6 so that it presses against the upper end of the fuse 8. A first escape groove 33 is defined in the fixed cover 3. As the detent 6 rotates, it passes through the first escape groove 33 and presses against the upper end of the fuse 8. The provision of the first escape groove 33 prevents interference between the detent 6 and the fixed cover 3.

[0048] Reference Figure 1-Figure 3 The push rod 42 is provided with a second avoidance groove 421, and the end of the pressing tongue 6 away from the fixed cover 3 extends into the second avoidance groove 421. Two sets of second control mechanisms 7 are symmetrically arranged on both sides of the pressing tongue 6. The second control mechanism 7 includes a movable cavity 72 and a limiting cavity 73, which are provided on the side wall of one side of the second avoidance groove 421 and are interconnected, and a roller body 71 slidably arranged in the limiting cavity 73 and the movable cavity 72. The limiting cavity 73 on the same side is located on the side of the movable cavity 72 away from the equipment platform 1. The two roller bodies 71 are both connected to the pressing tongue 6.

[0049] Reference Figure 1-Figure 3 When the roller body 71 is located in the movable cavity 72, the pressing tongue 6 can rotate around the hinge; when the roller body 71 is located in the limiting cavity 73, the pressing tongue 6 cannot rotate. When the pressing tongue 6 presses against the upper end of the fuse 8, the roller body 71 is located in the limiting cavity 73; in the initial state, the roller body 71 is located in the movable cavity 72.

[0050] The steps for disassembling and assembling the fuse 8 in this embodiment are as follows:

[0051] Reference Figure 1 、 Figure 5 When installing the fuse 8, the worker first grasps the upper end of the fuse 8 with one hand and supports the fuse 8 with the other hand, holding the fuse 8 horizontally. Then, the worker inserts the lower end of the fuse 8 into the slot 22. The worker then releases the hand holding the fuse 8 and pushes the fuse 8 upward with the hand holding the upper end of the fuse 8, causing the fuse 8 to rotate with the turntable 21. During this process, the turntable 21 presses against the top plate 53, causing the top plate 53 to move downward, compressing the two first springs 23 and causing the limit plate 24 to move downward.

[0052] Reference Figure 1 、 Figure 5-Figure 7, and finally the fuse 8 presses the turntable 21 against the mounting base 2, and at this time the limit plate 24 also moves to disengage from the handle 43. Without the restriction of the limit plate 24, the two second springs 41 will rebound and drive the fixed cover 3 to move downward. During the downward movement of the fixed cover 3, the top rod 42 will move close to the equipment platform 1. When the top rod 42 moves close to the equipment platform 1, the roller body 1 71 will move from the movable cavity 72 to the limit cavity 73. When the roller body 1 71 moves into the limit cavity 73, the pressing tongue 6 rotates and presses the upper end of the fuse 8. At this time, the fixed cover 3 has not moved to abut against the upper end of the fuse 8. In this way, the pressing tongue 6 can assist the technician in holding the fuse 8.

[0053] Reference Figure 1 、 Figures 8-10 Subsequently, the two second springs 41 rebound and press the fixing cover 3 onto the upper end of the fuse 8, so that the fixing cover 3 cooperates with the card slot 22 to fix the fuse 8, completing the installation operation of the fuse 8.

[0054] Reference Figure 1 、 Figure 5-Figure 7 When fuse 8 is to be removed and replaced, the technician first holds the column of fuse 8 with one hand, and then uses the other hand to pull handle 43 to move the push rod 42 away from the equipment platform 1. As the push rod 42 moves away from the equipment platform 1, it pushes the fixed cover 3 upward, releasing the fixed cover 3 from fixing the fuse 8. At the same time, as the push rod 42 moves away from the equipment platform 1, the roller body 1 71 moves closer to the movable cavity 72.

[0055] Reference Figure 1 、 Figure 5-Figure 7 After the fixed cover 3 completely moves away from the upper end of the fuse 8, the roller body 71 is still located in the limiting cavity 73, so the pressing tongue 6 is still in the pressing state on the upper end of the fuse 8, which can assist the technician to hold the fuse 8.

[0056] Reference Figure 1 、 Figure 4-Figure 7 After the fixed cover 3 moves away from the upper end of the fuse 8, the technician can move the hand holding the fuse 8 up to grasp the upper end of the fuse 8, and then apply force to the fuse 8 to make the fuse 8 rotate with the turntable 21. After the fuse 8 rotates out of the movement path of the fixed cover 3, the technician's hand holding the handle 43 can cancel the grip on the handle 43, and hold the fuse 8 together to let the fuse 8 slowly fall down. When the fuse 8 falls down, the two first springs 23 will also rebound and drive the top plate 53 to rise to assist the falling of the fuse 8.

[0057] Reference Figure 1 、 Figure 4-Figure 7, after the fuse 8 is tilted to a certain angle, the fuse 8 is pulled out of the slot 22. After the fuse 8 is pulled out of the slot 22, the technician first steps on the turntable 21 to press the turntable 21 against the mounting base 2, allowing the top plate 53 and the limit plate 24 to move downward to prevent the top plate 53 from interfering with the reset of the handle 43. The technician then pulls the handle 43 and the top rod 42 back to their initial positions, and then stops stepping on the turntable 21. The two first springs 23 will rebound, causing the limit plate 24 to move upward and back against the handle 43, completing the limit of the handle 43 and facilitating the installation of a new fuse 8. The above structure allows one person to easily complete the disassembly and assembly of the fuse 8. Example 2:

[0058] An energy storage box-type transformer applies the above-mentioned high-voltage switch structure.

[0059] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
