Description
Technical Field
[0001] The present invention relates to the field of transformers, and particularly to an energy storage box-type transformer and its high-voltage switch structure. Background Art
[0002] Chinese Patent with Publication No. CN207938519U discloses a high-voltage vacuum load switch-fuse combination electrical appliance, including a frame on which a fuse is installed. When placing the fuse of the above patent, first hold the fuse vertically, then place the fuse vertically into the copper plate, and then connect the clamping member to the fuse to complete the installation of the fuse.
[0003] The fuse of the above device adopts a vertical plug-in installation method. Since the fuse is a cylinder and its surface is smooth, it is difficult for technicians to firmly grasp the fuse during vertical installation, which increases the construction difficulty for technicians. Therefore, the installation and disassembly of the fuse of the above device are relatively difficult. Summary of the Invention
[0004] This application provides an energy storage box-type transformer and its high-voltage switch structure, which realizes the rapid disassembly and assembly of the fuse through the methods of horizontal plug-in and rotation, and has the characteristics of simple operation, labor-saving and high efficiency.
[0005] The high-voltage switch structure provided by this application adopts the following technical solutions: A high-voltage switch structure includes an equipment platform, on which an insulator and an earthing switch are provided. A fixing frame is provided on the insulator, and the earthing switch is connected to the fixing frame. An installation seat is provided on the fixing frame, and a turntable is hinged on the installation seat. A card slot is provided on the turntable, and the card slot is in plug-in fit with the lower end of the fuse. A first spring is provided on the installation seat, and the elastic force of the first spring acts on the turntable to make the turntable in a flipped state. When the turntable is in the flipped state, the notch of the card slot faces away from the equipment platform. An installation head is provided on the equipment platform, and a fixing cover for pressing the upper end of the fuse is slidably connected along the Z-axis direction on the installation head. The fixing cover is located above the installation seat. A driving mechanism for driving the movement of the fixing cover is also provided on the equipment platform. When the lower end of the fuse is inserted into the card slot and the fuse presses the turntable against the installation seat, the upper end of the fuse is located below the fixing cover and on the movement path of the fixing cover.
[0006] By adopting the above technical solution, when installing the fuse, a worker grabs the upper end of the fuse with one hand and then holds the fuse with the other hand, supporting the fuse in a horizontal holding manner. This method can firmly hold the fuse. Then, insert the lower end of the fuse into the card slot, and then release the hand supporting the fuse. The hand holding the upper end of the fuse pushes the fuse upward forcefully, causing the fuse to rotate with the turntable. Eventually, the fuse presses the turntable against the mounting base. Then, the technician releases the grip on the upper end of the fuse and holds the fuse to make the fuse in a vertical installation state. Then, the driving mechanism drives the fixed cover to move downward so that the fixed cover sleeves and presses the upper end of the fuse to complete the installation and fixation of the fuse. When disassembling 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 releases the fixation of the upper end of the fuse. Then, the technician grabs the upper end of the fuse and forces the fuse to tilt, causing the fuse to tilt towards the technician's body. When the fuse tilts, the first spring will also assist the tilting of the fuse by driving the turntable to rotate. After the fuse lies horizontally, just pull out the lower end of the fuse from the card slot. Compared with the vertical plug-in installation method, the installation method of this application is more labor-saving and convenient.
[0007] Preferably, the driving mechanism includes a second spring provided on the mounting head, a push rod slidably connected to the equipment platform in the X-axis direction, and a handle fixed on the push rod; the second spring abuts against the fixed cover, and the second spring always drives the fixed cover to move towards the mounting base; the push rod abuts against the fixed cover, 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 base.
[0008] 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 make the push rod move away from the equipment platform. When the push rod moves away from the equipment platform, it will push the fixed cover upward and compress the second spring. After the fixed cover moves up to a certain height, the technician holding the fuse horizontally inserts the lower end of the fuse into the card slot and makes the fuse vertical. Then, the technician holding the handle releases the handle, and 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 to complete the installation of the fuse.
[0009] Preferably, a limit plate is slidably connected to the mounting base in the Z-axis direction. The limit plate is used to cooperate with the handle to limit the movement of the push rod towards the equipment platform. A first control mechanism for controlling the sliding of the limit plate is also provided on the mounting base. In the initial state, the limit plate is at the highest point and abuts against the handle to limit the movement of the push rod close to the equipment platform. At this time, the push rod is at the position farthest from the equipment platform in its movement path, and the push rod jacks up the fixed cover so that the fixed cover is at the highest point.
[0010] By adopting the above technical solution, after the fuse is inserted into the card slot and vertically, the first control mechanism controls the limit plate to move downward and finally allows the limit plate to move away from the handle. Without the restriction of the limit plate, the second spring will drive the fixed cover to move downward, and finally the second spring will press the fixed cover onto the upper end of the fuse to complete the installation and fixation of the fuse.
[0011] Preferably, the first control mechanism includes a slide groove provided on the mounting seat, a guide rod provided in the slide groove, a top plate slidably connected to the guide rod 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.
[0012] By adopting the above technical solution, after the fuse is inserted into the card slot and vertically, the limit plate moves down and just moves to be separated from the handle, and then the fixed cover will move down under the action of the second spring and press and fix the upper end of the fuse. This setting allows one person to complete the installation of the fuse. When the old fuse needs to be replaced, the technician first holds the column of the fuse with one hand, and then uses the other hand to pull the handle to move the top rod away from the equipment platform. The top rod moves away from the equipment platform and moves up against the fixed cover, canceling the fixation of the fixed cover on the fuse. Then the technician's hand holding the fuse slowly moves up and finally grasps the upper end of the fuse, and then applies force to the fuse to make the fuse rotate with the turntable. After the fuse rotates out of the movement path of the fixed cover, the technician's hand holding the handle can cancel the grip of the handle, and together hold the fuse to let the fuse slowly tip over, so that the fuse can be pulled out of the card slot. After the fuse is pulled out of the slot, the technician first steps on the turntable to press it against the mounting seat, then pulls the handle and the push rod back to the initial position, and then stops stepping on the turntable. The first spring will rebound to make the limit plate move up and abut against the handle again, thus completing the limit of the handle and facilitating the installation of a new fuse. The above structure allows one person to easily complete the replacement of the fuse.
[0013] Preferably, a pressing tongue is hinged on the mounting head, and a second control mechanism is also 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.
[0014] By adopting the above technical solution, when disassembling the old fuse, the second control mechanism is used to make the pressure tongue rotate and 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 by hand. The above structure can assist the technician in holding the fuse when disassembling the old fuse, preventing the phenomenon that the technician cannot firmly grasp the fuse and the fuse topples due to gravity.
[0015] Preferably, the second control mechanism includes a movable cavity and a limiting cavity that are opened on the ejector rod and communicate with each other, and a first roller that is slidably arranged in the limiting cavity and the movable cavity. The limiting cavity is located on the side of the movable cavity away from the equipment platform, and the first roller is connected to the end of the pressure tongue away from the fixed cover; when the first roller is located in the movable cavity, the pressure tongue can rotate around the hinge; when the first roller is located in the limiting cavity, the pressure tongue cannot rotate, and the pressure tongue presses against the upper end of the fuse when the first roller is located in the limiting cavity; in the initial state, the first roller is located in the movable cavity.
[0016] By adopting the above technical solution, during the downward movement of the fixed cover, the ejector rod will move closer to the equipment platform. When the ejector rod moves closer to the equipment platform, the first roller will move from the movable cavity to the limiting cavity. When the first roller moves into the limiting cavity, the pressure tongue rotates and presses against the upper end of the fuse. At this time, the fixed cover has not moved to abut against the upper end of the fuse, and at this time, the pressure tongue can assist the technician in holding the fuse. During the disassembly process of the fuse, the technician will pull the handle and the ejector rod will move away from the equipment platform, causing the ejector rod to push the fixed cover upward, and at the same time, the first roller will move closer to the movable cavity. After the fixed cover completely moves away from the upper end of the fuse, the first roller is still located in the limiting cavity, so the pressure tongue is still in the pressing state against the upper end of the fuse, which can assist the technician in holding the fuse at this time and facilitate the technician to move the hand holding the fuse and grasp the upper end of the fuse.
[0017] A kind of energy storage box-type transformer provided by the present application adopts the following technical solution: Preferably, the above high-voltage switch structure is applied.
[0018] By adopting the above technical solution, the disassembly and installation difficulty of the fuse in the transformer is reduced.
[0019] The technical effects of the present invention are mainly reflected in the following aspects: 1. The present invention reduces the installation difficulty of the fuse by adopting the method of horizontally inserting and rotating to install the fuse; 2. The present invention completes the automatic fixation of the fuse through the cooperation of components such as the second spring and the fixed cover; 3. The present invention sets a pressure tongue and a second control mechanism to assist in the installation and disassembly of the fuse. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0031] The following further elaborates on the present invention in conjunction with the attached drawings to make the technical solutions of this application easier to understand and master. Embodiment 1:
[0032] Reference Figure 1 , a high - voltage switch structure according to this embodiment includes an equipment platform 1. An insulator 11 and an earthing switch 12 are provided on the equipment platform 1. A fixing frame 13 is provided on the insulator 11, and the earthing switch 12 is connected to the fixing frame 13.
[0033] Reference Figures 1-3 , an installation head 14 is fixed on the equipment platform 1. A fixing cover 3 for pressing the upper end of a fuse 8 is slidably connected to the installation head 14 along the Z - axis direction. Two rod bodies 31 are integrally formed on the fixing cover 3, and the two rod bodies 31 slide along with the fixing cover 3 and are connected to the installation head 14.
[0034] Reference Figures 1-3 , two limiting blocks 32 are integrally formed on each of the two rod bodies 31, and the two rod bodies 31 are located between the two limiting blocks 32. Two limiting grooves 141 are formed on the installation head 14, and the two limiting blocks 32 are slidably connected to the two limiting grooves 141 along the Z - axis direction respectively. The cooperation between the two limiting blocks 32 and the two limiting grooves 141 prevents the fixing cover 3 and the two rod bodies 31 from detaching from the installation head 14. In this embodiment, damping pads can be provided in the two limiting grooves 141 to control the movement speed of the limiting blocks 32, and ultimately achieve the purpose of controlling the movement speed of the fixing cover 3.
[0035] Reference Figures 1-3 , a driving mechanism 4 for driving the fixing cover 3 to move is also provided on the equipment platform 1. The driving mechanism 4 includes two second springs 41. The two second springs 41 are respectively sleeved on the two rod bodies 31. One end of each of the two second springs 41 abuts against the installation head 14, and the other ends of the two second springs 41 respectively abut against two limiting blocks on the fixing cover 3. The two second springs 41 are always in a compressed state under force, and the second springs 41 always drive the fixing cover 3 to move towards the ground.
[0036] Reference Figures 1-3 , the driving mechanism 4 further includes a push rod 42 slidably connected to the equipment platform 1 along the X - axis direction and a handle 43 fixed on the push rod 42. The push rod 42 is located on the side of the fixing cover 3 close to the equipment platform 1. The end of the push rod 42 away from the equipment platform 1 abuts against the fixing cover 3. The mutually - abutting surfaces of the push rod 42 and the fixing cover 3 are both inclined planes, which is convenient for force transmission. When the push rod 42 moves away from the equipment platform 1, it drives the fixing cover 3 to move away from the mounting seat 2.
[0037] Reference Figure 1 and Figure 2 , a mounting seat 2 is fixed on the fixing frame 13. The mounting seat 2 is located below the fixing cover 3. A limiting plate 24 is slidably connected to the mounting seat 2 along the Z - axis direction. The limiting plate 24 is used to cooperate with the handle 43 to limit the movement of the push rod 42 towards the equipment platform 1 direction.
[0038] Referring to Figure 1 and Figure 4 , a first control mechanism 5 for controlling the sliding of the limiting plate 24 is further provided on the mounting base 2. The first control mechanism 5 includes a sliding groove 51 formed in the mounting base 2, two guide rods 52 fixed in the sliding groove 51, and a top plate 53 slidably connected to the two guide rods 52 along the Z-axis direction. The limiting plate 24 is fixed to...
[0039] Referring to Figures 1-4 , first springs 23 are sleeved on both of the two guide rods 52. One ends of the two first springs 23 are both abutted against the bottom wall of the sliding groove 51, and the other ends of the two first springs 23 are both abutted against the top plate 53. The two first springs 23 always drive the top plate 53 to move towards the fixed cover 3. In the initial state, the two first springs 23 push the top plate 53 out of the sliding groove 51. The top plate 53 and the limiting plate 24 are at the highest point. The limiting plate 24 abuts against the handle 43. The limiting plate 24 is located on the side of the handle 43 close to the equipment platform 1. The limiting plate 24 restricts the movement of the handle 43 and the ejector rod 42 close to the equipment platform 1. At this time, the ejector rod 42 is at the position farthest from the equipment platform 1 in its movement path. The ejector rod 42 jacks up the fixed cover 3 so that the fixed cover 3 is at the highest position.
[0040] Referring to Figure 1 and Figure 4 , a turntable 21 is hinged on the mounting base 2. The hinge axis of the turntable 21 is parallel to the Y-axis. A card slot 22 is provided on the turntable 21. The lower end of the fuse 8 is inserted and matched with the card slot 22. When the lower end of the fuse 8 is inserted into the card slot 22 and the fuse 8 presses the turntable 21 against the mounting base 2, the upper end of the fuse 8 is located below the fixed cover 3 and is on the movement path of the fixed cover 3.
[0041] Referring to Figure 1 and Figure 4 , the turntable 21 abuts against the top plate 53; the top plate 53 is located between the turntable 21 and the two first springs 23. In the initial state, the two first springs 23 push the top plate 53 out of the sliding groove 51 so that the top plate 53 jacks up the turntable 21 to make the turntable 21 in a flipped state. When the turntable 21 is in a flipped state, the notch of the card 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 limiting plate 24 will slide into the sliding groove 51. When the turntable 21 moves to abut against the mounting base 2, the limiting plate 24 moves away from the handle 43.
[0042] Referring to Figures 1-3, a tongue depressor 6 is hinged on the installation head 14, and the hinge axis of the tongue depressor 6 is parallel to the Y-axis. Two groups of second control mechanisms 7 are further provided on the ejector rod 42, and the second control mechanism 7 is used to drive the tongue depressor 6 to rotate so that the tongue depressor 6 presses against the upper end of the fuse 8. A first avoidance groove 33 is formed on the fixed cover 3. When the tongue depressor 6 rotates, it passes through the first avoidance groove 33 and then presses against the upper end of the fuse 8. By providing the first avoidance groove 33, interference between the movement of the tongue depressor 6 and the fixed cover 3 is prevented.
[0043] Refer to Figures 1-3 , wherein a second avoidance groove 421 is formed on the ejector rod 42, and the end of the tongue depressor 6 away from the fixed cover 3 extends into the second avoidance groove 421. The two groups of second control mechanisms 7 are symmetrically arranged on both sides of the tongue depressor 6. The second control mechanism 7 includes a movable cavity 72 and a limit cavity 73 that are formed on one side wall of the second avoidance groove 421 and communicate with each other, and a first roller 71 that is slidably arranged in the limit cavity 73 and the movable cavity 72. The limit cavity 73 on the same side is located on the side of the movable cavity 72 away from the equipment platform 1, and both first rollers 71 are connected to the tongue depressor 6.
[0044] Refer to Figures 1-3 , when the first roller 71 is located in the movable cavity 72, the tongue depressor 6 can rotate around the hinge; when the first roller 71 is located in the limit cavity 73, the tongue depressor 6 cannot rotate. When the tongue depressor 6 presses against the upper end of the fuse 8, the first roller 71 is located in the limit cavity 73; in the initial state, the first roller 71 is located in the movable cavity 72.
[0045] The disassembly and assembly steps of the fuse 8 in this embodiment are as follows: Refer to Figure 1 、 Figure 5 , when installing the fuse 8, first, a worker grabs the upper end of the fuse 8 with one hand and then holds the fuse 8 with the other hand. The fuse 8 is held in a horizontal embrace and then the lower end of the fuse 8 is inserted into the card slot 22. Then, the hand holding the fuse 8 is released, and the hand grabbing the upper end of the fuse 8 pushes the fuse 8 upward forcefully, so that the fuse 8 drives the turntable 21 to rotate. During this process, the turntable 21 will press against the top plate 53, causing the top plate 53 to move downward, so that the two first springs 23 are compressed and the limit plate 24 moves downward.
[0046] Refer to Figure 1 、 Figures 5-7, finally, the fuse 8 presses the turntable 21 against the mounting base 2. At this time, the limiting plate 24 just moves away from the handle 43. Without the restriction of the limiting 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 ejector rod 42 will move closer to the equipment platform 1. When the ejector rod 42 moves closer to the equipment platform 1, the first roller 71 will move from the movable cavity 72 to the limiting cavity 73. When the first roller 71 moves into the limiting cavity 73, the pressure tongue 6 rotates and presses against the upper end of the fuse 8. At this time, the fixed cover 3 has not yet moved to abut against the upper end of the fuse 8, so that the pressure tongue 6 can assist the technician in holding the fuse 8.
[0047] Refer to Figure 1 , Figures 8-10 , subsequently, the two second springs 41 rebound and press the fixed cover 3 against the upper end of the fuse 8, so that the fixed cover 3 cooperates with the card slot 22 to fix the fuse 8 together, completing the installation operation of the fuse 8.
[0048] Refer to Figure 1 , Figures 5-7 , when the fuse 8 needs to be disassembled and replaced, the technician first holds the column of the fuse 8 with one hand, and then uses the other hand to pull the handle 43 to make the ejector rod 42 move away from the equipment platform 1. When the ejector rod 42 moves away from the equipment platform 1, it will push the fixed cover 3 upward, canceling the fixation of the fixed cover 3 on the fuse 8. At the same time, during the process of the ejector rod 42 moving away from the equipment platform 1, the first roller 71 will move closer to the movable cavity 72.
[0049] Refer to Figure 1 , Figures 5-7 , after the fixed cover 3 completely moves away from the upper end of the fuse 8, the first roller 71 is still located in the limiting cavity 73. Therefore, the pressure tongue 6 is still in the state of pressing against the upper end of the fuse 8, so that it can assist the technician in holding the fuse 8.
[0050] Refer to Figure 1 , Figures 4-7 , after the fixed cover 3 moves away from the upper end of the fuse 8, the hand of the technician holding the fuse 8 can move upward 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 hand of the technician grasping the handle 43 can cancel the grasp of the handle 43 and together hold the fuse 8 to make the fuse 8 slowly tilt. When the fuse 8 tilts, the two first springs 23 will also rebound to assist the tilting of the fuse 8 by driving the top plate 53 to rise.
[0051] Refer to Figure 1 , Figures 4-7, after the fuse 8 is tilted at a certain angle, the fuse 8 is pulled out of the card slot 22. After the fuse 8 is pulled out of the card slot 22, the technician first steps on the turntable 21 to press the turntable 21 against the mounting base 2, so that the top plate 53 and the limiting plate 24 move downward to prevent the top plate 53 from interfering with the reset of the handle 43. Then the technician pulls the handle 43 and the ejector rod 42 back to the initial position, and then cancels the stepping on the turntable 21. The two first springs 23 will rebound so that the limiting plate 24 moves upward and abuts against the handle 43 again, completing the limiting of the handle 43 and facilitating the installation of the new fuse 8. Through the above structure, a person can easily complete the disassembly and assembly operation of the fuse 8. Embodiment 2:
