Description

Technical Field

[0001] This invention relates to the field of current transformer installation, and more specifically, to a quick-installation and disassembly current transformer installation device and method. Background Technology

[0002] A transformer (or current transformer) is a device used in power systems for current and voltage measurement, control, and protection. It uses the principle of electromagnetic induction to convert larger or higher voltages / currents into lower, more easily measurable signals, ensuring safe and effective measurement and control. A current transformer, in particular, is an electromagnetic induction device primarily used to convert high currents into lower-ratio, safer, and more easily measurable signals for protection. It is crucial in power systems, ensuring the safety and accuracy of measurement, control, and protection.

[0003] For example, a current transformer disclosed in Chinese Patent Publication No. CN205282277U solves the problem that it is difficult to detect when the temperature of the transformer housing exceeds its maximum allowable temperature, which can easily lead to accidents. The key technical points of this solution are: it includes a transformer housing with an alarm device. The alarm device includes: a temperature detection unit for detecting the temperature of the transformer housing and outputting a corresponding temperature detection signal; a control unit that responds to the temperature detection signal and outputs a corresponding control signal; and an alarm unit that responds to the control signal to activate or deactivate the alarm function. In this current transformer, the temperature detection unit can detect the temperature of the transformer housing and then transmit the acquired value to the control unit. When the temperature of the transformer housing exceeds its maximum allowable temperature, the control unit outputs a control signal to cause the alarm unit to sound an alarm, reminding personnel to take safety measures.

[0004] The current transformers in the above technical solutions are usually installed in switch cabinets. However, after a large number of electrical components are installed in the switch cabinet, the space left for the installation of the transformers is limited. Furthermore, the limited space around the installation location of the transformer restricts the operator's hand movement and tool use, which increases the difficulty of disassembly and assembly and affects the efficiency of disassembly and assembly.

[0005] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a quick-installation and disassembly device and method for current transformers. The installation and disassembly of the current transformer can be completed with just one push and one press, and the installation and disassembly efficiency will not be affected by space limitations.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a quick-installation and disassembly current transformer installation device and installation method, comprising: a current transformer, wherein single-hole plug-in sockets are fixed on both sides of the current transformer;

[0008] The mounting mechanism is used to quickly fix and install the current transformer.

One end of each of the two plug-in posts is provided with an inner groove. The two mounting grooves are respectively connected to the two inner grooves. The inner surface of each of the two inner grooves is provided with two through holes.

[0009] Both of the through holes have a recessed rotating seat on their inner side, and both of the recessed rotating seats have a locking head on their inner side.

[0010] Both inner grooves are provided with a retraction component on their inner sides, both mounting grooves are provided with a push-out component on their inner sides, and the mounting base is provided with a telescopic steering component, which is used to adjust the position and angle of the mounting base.

[0011] By adopting the above technical solution, the two single-hole plug-in sockets on the current transformer are respectively fitted into the two plug-in posts.

[0014] Both of the triangular blocks have rotatable push-pull rods on their outer surfaces, one end of each push-pull rod is rotatably connected to two push plates, and both of the triangular blocks have double grooves on their outer surfaces, with an H-shaped plate sliding between the two double grooves.

[0015] The present invention is further configured such that: the telescopic steering component includes a telescopic component, the telescopic component includes a connecting seat, the front side of the connecting seat is provided with two transverse grooves, the inner surface of each of the two transverse grooves is provided with a sliding groove, a sliding seat is slidably disposed in each of the two sliding grooves, a telescopic rod is rotatably disposed on each of the two sliding seats, one end of each of the two telescopic rods is connected to a mounting seat through a rotating component, the other end of each of the two telescopic rods is provided with a telescopic groove, and a positioning component is provided on the inner side of each of the two transverse grooves.

[0016] The present invention is further configured such that: the positioning component includes a telescopic column that slides inside the telescopic groove, a first magnetic suction plate fixed to the top of the inner wall of the transverse groove, a limiting piece fixed to the slide block, and two fixing strips fixed to the inner side wall of the transverse groove;

[0017] One end of the telescopic column extends to the top of the limiting plate, and a shifting plate is fixed to one end of the telescopic column. Two locking holes are provided on the top of the shifting plate, and a second magnetic suction plate is provided on the top of the shifting plate. At least two inner holes are provided at the bottom of the two fixing strips. An inclined cylinder slides inside the inner hole, and a third spring is provided between the top of the inner wall of the inner hole and one end of the inclined cylinder.

[0018] The present invention is further configured such that: the rotating component includes a fixed base, the outer surface of the fixed base is provided with two rotating grooves, one end of each of the two telescopic rods rotates within the two rotating grooves, the interior of the fixed base is provided with a mounting groove, a rotating shaft is rotatably mounted on the inner side of the mounting groove, one end of the rotating shaft extends to the outside of the fixed base and is fixed to the mounting base, the outer surface of the rotating shaft is provided with a rotating groove, and a driving component is provided on the inner side of the rotating groove.

[0019] The present invention is further configured such that: the driving component is used to drive the rotating shaft to rotate; the driving component includes a guide rod fixed inside the mounting groove and a lead screw rotating inside the mounting groove; a driving arm slides on the outer surface of the guide rod; one end of the driving arm passes through the interior of the rotating groove; the driving arm is threaded to the outer surface of the lead screw; and one end of the lead screw extends to the outside of the fixed seat and is fixed with an anti-slip knob.

[0020] A method for installing a quick-assembly and disassembly current transformer mounting device includes the following steps:

[0021] Step 1: Before installing the current transformer, fix the mounting mechanism in a suitable position with bolts and double-hole connecting plates. Insert the two single-hole plugs into the two plugs respectively. The two locking heads rotate into the concave rotating seat under the pushing of the single-hole plugs. After the single-hole plugs are attached to the mounting seat, the locking heads reset and press against the front of the single-hole plugs to complete the installation of the current transformer.

[0022] Step 2: Press down on the two connecting pieces respectively. The insert rod will drive the fixing piece and the drive rod to slide. The drive rod will drive the concave rotating seat and the locking head to deflect into the inner groove, releasing the locking head from the single-hole plug-in seat. At the same time, push the H-shaped plate so that the triangular block drives the push-pull rod to push the push plate. The push plate pushes the single-hole plug-in seat out of the plug-in post to complete the disassembly.

[0023] Step 3: Pull the mounting base, and the fixed base will pull the telescopic rod and slide. At this time, the telescopic rod will deflect away from the connecting base, thereby pushing the fixed base and mounting base away from the connecting base, so that the current transformer can be moved out of the congested space, making it easier to disassemble and assemble the current transformer.

[0024] Step 4: Rotate the anti-slip knob to drive the lead screw to rotate. The drive arm moves along the lead screw under the action of the guide rod. The thrust of the drive arm moving in the rotating groove drives the rotating shaft to rotate, thereby causing the mounting base and the current transformer to deflect at a certain angle, increasing the flexibility during installation.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. Insert the two single-hole sockets on the current transformer into the two corresponding plug posts. The locking head will rotate into the concave rotating seat under the push of the single-hole socket. After the single-hole socket is attached to the mounting base, the locking head will return to its original position and press against the front of the single-hole socket to complete the installation. When disassembling, press the connecting piece. The insertion rod will deflect the locking head to the inner groove through the drive rod. The push-pull rod will be pushed by the H-shaped plate and the triangular block, so that the pushing plate will remove the single-hole socket from the plug post. The current transformer can be disassembled and assembled with just one push and one press. The disassembly and assembly will not be affected by space limitations, which will increase the difficulty of disassembly and assembly and affect the efficiency.

[0027] 2. Pulling the mounting base causes the fixed base to slide along the sliding groove along the telescopic rod and slide block. The telescopic rod will deflect away from the connecting base, thereby pushing the fixed base and mounting base away from the connecting base. This pushes out the current transformer and its mounting structure on the mounting base, and the telescopic rod is fixed by the inclined cylinder and the locking hole. This moves the current transformer out of the crowded surrounding space, making it easier to disassemble, install, and maintain the current transformer. It also allows for proper adjustment of the current transformer's installation position to avoid excessive crowding caused by stacking it up and down.

[0028] 3. When it is necessary to change the orientation of the current transformer during maintenance or due to space requirements, the anti-slip knob can be rotated to rotate the lead screw, thereby causing the drive arm to move along the lead screw under the action of the guide rod. When the drive arm moves, it will move in the rotating groove. The thrust of the drive arm moving in the rotating groove will drive the rotating shaft to rotate, thereby causing the mounting base and the current transformer to deflect at a certain angle, increasing the flexibility of installation.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings.

[0039] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0040] like Figure 1-8 As shown, a quick-installation and disassembly instrument transformer installation device and method include an instrument transformer 1 and an installation mechanism 3. Single-hole connectors 2 are fixed to both sides of the instrument transformer. The installation mechanism 3 is used to quickly fix and install the instrument transformer 1. The installation mechanism 3 includes a mounting base 31. Connecting posts 32, whose dimensions are adapted to the holes on the single-hole connectors 2, are fixed to both sides of the front of the mounting base 31. Mounting grooves 33, corresponding to the positions of the connecting posts 32, are opened on both sides of the front of the mounting base 31. An inner groove 34 is opened at one end of each of the two connecting posts 32. Two mounting slots 33 are connected to two inner slots 34 respectively. Two through holes 35 are opened on the inner surface of each inner slot 34. A concave rotating seat 36 is rotatably mounted on the inner side of each through hole 35. A locking head 37 is rotatably mounted on the inner side of each concave rotating seat 36. A positive magnetic plate 38 is fixed on the inner surface of each concave rotating seat 36. A negative magnetic plate 39 is fixed on the outer surface of each locking head 37. When no external force is applied to the locking head 37, the locking head 37 protrudes from the outer surface of the insertion post 32.

[0041] Both inner grooves 34 are equipped with a retraction component on their inner sides. Both sides of the two concave rotating seats 36 are provided with inclined grooves 310. The retraction component is used to rotate the concave rotating seats 36 into the inner grooves 34. The retraction component includes an insertion rod 311 that passes through the insertion post 32 and a drive rod 315 that slides in the inclined groove 310. A connecting piece 312 is fixed to one end of the insertion rod 311 outside the insertion post 32. A fixing piece 313 is fixed to the outer surface of the insertion rod 311. The fixing piece 313 is fixedly connected to the drive rod 315. A groove is provided on the inner surface of the inner groove 34 at the position corresponding to the drive rod 315. One end of the drive rod 315 slides in the groove to help limit the sliding path of the drive rod 315 and the insertion rod 311. A first spring 314 is fixed between the fixing piece 313 and the inner groove 34. When the first spring 314 is at its original length and no external force is applied, the fixing piece 313 drives the drive rod 315 to the lower end of the inclined groove 310.

[0042] Both mounting slots 33 have push-out components on their inner sides. The mounting base 31 has two corresponding hidden slots 316 on both sides of its front side. Each push-out component includes two mounting rods 317 fixed to the top and bottom of the inner wall of the mounting slot 33, and push plates 318 sliding in the two hidden slots 316. Triangular blocks 319 slide on the outer surfaces of both mounting rods 317, with their inclined surfaces facing each other. A second spring 320 is fixed to the outer surface of each of the two triangular blocks 319. The other end of the second spring 320... Fixed on the inner wall of the mounting groove 33, two second springs 320 are respectively sleeved on the outside of the two mounting rods 317. The outer surfaces of the two triangular blocks 319 are rotatably equipped with push-pull rods 321. One end of the two push-pull rods 321 is rotatably connected to the two push plates 318 respectively. The outer surfaces of the two triangular blocks 319 are provided with double grooves 322. An H-shaped plate 323 slides between the two double grooves 322. The size of the horizontal plate in the H-shaped plate 323 is smaller than the distance between the two mounting rods 317. There is a certain distance between the H-shaped plate 323 and one end of the through rod 311.

[0043] Before installing the current transformer 1, the mounting mechanism 3 is fixed in a suitable position using bolts and a double-hole connecting plate. Then, the two single-hole plug-in seats 2 on the current transformer 1 are respectively fitted onto the two plug-in posts 32 on the mounting base 31. As the single-hole plug-in seats 2 are fitted onto the plug-in posts 32 and move toward the surface of the mounting base 31, the two protruding locking heads 37 on the plug-in posts 32 will rotate into the concave rotating seat 36 under the pushing of the single-hole plug-in seats 2 until the single-hole plug-in seats 2 are completely fitted onto the mounting base 31. At this time, the compression on the locking heads 37 will disappear, and the locking heads 37 will be reset under the repulsive action of the positive magnetic plate 38 and the negative magnetic plate 39. The locking heads 37 will press against the front of the single-hole plug-in seats 2 to prevent the single-hole plug-in seats 2 from sliding off the plug-in posts 32, thus completing the installation of the current transformer 1.

[0044] When the current transformer 1 needs to be replaced, press the connecting pieces 312 on both sides of the current transformer 1 with your thumbs to press the connecting pieces 312 toward one end of the plug-in post 32. The connecting pieces 312 will push the insertion rod 311 to move the fixing piece 313. The fixing piece 313 will pull the first spring 314 and drive the drive rod 315 to slide in the groove. When the drive rod 315 slides, it slides in the inclined groove 310, pulling the inclined groove 310 downward. This causes the concave rotating seat 36 to drive the locking head 37 to deflect into the inner groove 34, releasing the locking head 37 from the single-hole plug-in seat 2. After the concave rotating seat 36 drives the locking head 37 to deflect into the inner groove 34, the insertion rod 311 continues to move under force to push the H-shaped plate 323. The H-shaped plate 323 will push the two triangular blocks 319 to move away from each other. 19 will drive the push-pull rod 321 to move its connected end. At the same time, the push-pull rod 321 will deflect away from the mounting rod 317 when it moves, pushing the push plate 318 out of the hidden groove 316. The push plate 318 will push the single-hole plug 2 to the position of the locking head 37. The current transformer 1 can be pulled out by releasing the connecting piece 312. The locking head 37 is restricted to prevent the locking head 37 from automatically deflecting out and obstructing the single-hole plug 2 from moving out. When disassembling, the current transformer 1 can be easily disassembled with just one press. It is easy, convenient and saves time and effort. After the single-hole plug 2 is removed from the position of the locking head 37, the two triangular blocks 319 will drive the H-shaped plate 323 to automatically reset under the elastic force of the second spring 320. The insertion rod 311 will automatically reset under the elastic force of the first spring 314, so that the locking head 37 is reset for the next installation.

[0045] The mounting base 31 is provided with a telescopic steering component, which is used to adjust the position and angle of the mounting base 31. The telescopic steering component includes a telescopic component and a connecting base 324. Both sides of the connecting base 324 are fixed with double-hole connecting plates. The connecting base 324 is fixed in a suitable installation position by bolts passing through the holes in the double-hole connecting plates. The front of the connecting base 324 has two vertically corresponding horizontal grooves 325. The inner surface of the two horizontal grooves 325 is provided with a sliding groove 326. The sliding blocks 327 with a cross-section of the uppercase letter L slide in the two sliding blocks 326. The two sliding blocks 327 are rotatably mounted on the two sliding blocks 327. One end of the two telescopic rods 328 is connected to the mounting base 31 through a rotating component. The other end of the two telescopic rods 328 is provided with a telescopic groove 329. The inner side of the two horizontal grooves 325 is provided with a positioning component.

[0046] The positioning components include a telescopic column 330 that slides inside the telescopic groove 329, a first magnetic suction plate 331 fixed to the top of the inner wall of the transverse groove 325, a limiting piece 332 fixed to the slide block 327, and two fixing strips 333 fixed to the inner side wall of the transverse groove 325. One end of the telescopic column 330 extends to the top of the limiting piece 332. Due to the restriction of the limiting piece 332, the telescopic column 330 can only move vertically within the limiting piece 332. When the telescopic rod 328 rotates, it will not cause the telescopic column 330 to rotate with it. One end of the telescopic column 330 is fixed with a shifting piece 334, and the top of the shifting piece 334 has two locking holes 335. The top of the transposition piece 334 is provided with a second magnetic suction plate 336, and the first magnetic suction plate 331 is provided at one end near the fixing strip 333. The first magnetic suction plate 331 and the second magnetic suction plate 336 are respectively N-pole magnet plate and S-pole magnet plate. The two attract each other, causing the transposition piece 334 to move upward. The bottom of each of the two fixing strips 333 is provided with at least two inner holes 337. An inclined cylinder 338 slides inside the inner hole 337. A third spring 339 is fixed between the top of the inner wall of the inner hole 337 and one end of the inclined cylinder 338. When the third spring 339 is at its original length, one end of the inclined cylinder 338 extends to the outside of the inner hole 337.

[0047] If the space around the installation location is too cramped and it is located deep inside, the mounting base 31 can be pulled out to a certain distance during disassembly and assembly, so that the mounting base 31 and the current transformer 1 can be moved to a more spacious position, which facilitates the disassembly and assembly work. Alternatively, the installation position of the current transformer 1 can be adjusted to a more spacious space, and the mounting base 31 can be pulled directly, so that the mounting base 31 pulls the telescopic rod 328 connected to it through the fixed base 340. The telescopic rod 328 will drive the slide 327 to slide along the slide groove 326. When the slide 327 slides, the telescopic rod 328 deflects away from the connecting base 324, thereby pushing the fixed base 340 and the mounting base 31 away from the connecting base 324, thereby pushing out the current transformer 1 and the mounting structure of the current transformer 1 on the mounting base 31, moving it out of the cramped space, and making it easier to disassemble and assemble the current transformer 1.

[0048] When the telescopic rod 328 and the slide block 327 slide, the shifting piece 334 pushes the inclined cylinder 338 through the inclined surface of the inclined cylinder 338 to squeeze the third spring 339 and slide into the inner hole 337. When the locking hole 335 on the shifting piece 334 corresponds to the inclined cylinder 338, the inclined cylinder 338 is pushed into the locking hole 335 under the reset of the third spring 339, thus fixing the position of the telescopic rod 328. This fixes the gap pushed out by the mounting base 31, preventing the mounting base 31 from being easily moved by force during disassembly, assembly or maintenance of the current transformer 1, which would affect work efficiency. If it is necessary to move the mounting base 31 back to the installation position, the mounting base 31 needs to be pulled further away from the connecting seat 324 until the slide block... 327 drives the telescopic rod 328 to one end of the slide groove 326. At this time, under the attraction of the first magnetic plate 331 and the second magnetic plate 336, the shifting piece 334 drives the telescopic column 330 to move upward. The shifting piece 334 moves to the space above the fixing strip 333. Then, the mounting base 31 is pushed towards the connecting base 324. The mounting base 31 drives the telescopic rod 328 and the slide 327 to move along the slide groove 326 to the original position. At this time, the shifting piece 334 will move with the telescopic rod 328 to one end of the fixing strip 333. Without the attraction of the first magnetic plate 331, the telescopic column 330 and the shifting piece 334 will fall back to their original positions. The shifting piece 334 will be below the fixing strip 333 again.

[0049] The rotating component includes a fixed base 340. Two connecting grooves 341 are formed on the outer surface of the fixed base 340. One end of each of the two telescopic rods 328 rotates within the two connecting grooves 341. A mounting groove 342 is formed inside the fixed base 340. A rotating shaft 343 rotates within the mounting groove 342. One end of the rotating shaft 343 extends to the outside of the fixed base 340 and is fixed to the mounting base 31. A rotating groove 344 is formed on the outer surface of the rotating shaft 343. A driving component is provided inside the rotating groove 344. The driving component drives the rotating shaft 343 to rotate, which in turn drives the mounting base 31 connected to it to deflect, thereby achieving the rotation of the rotating component. The current transformer 1 deflects, and the driving component includes a guide rod 345 fixed inside the mounting groove 342 and a lead screw 346 rotating inside the mounting groove 342. A driving arm 347 slides on the outer surface of the guide rod 345. One end of the driving arm 347 passes through the inside of the rotating groove 344. The driving arm 347 is threaded to the outer surface of the lead screw 346. One end of the lead screw 346 extends to the outside of the fixed seat 340 and is fixed with an anti-slip knob 348. An indicator arrow is provided on the anti-slip knob 348. The direction of the arrow is marked with "left" or "right", indicating which direction the mounting seat 31 will deflect when the anti-slip knob 348 is rotated in the specified direction.

[0050] When it is necessary to change the orientation of the current transformer 1 during maintenance or due to space requirements, the anti-slip knob 348 can be rotated directly. The anti-slip knob 348 will drive the lead screw 346 to rotate. The rotation of the lead screw 346 causes the drive arm 347 to move along the lead screw 346 under the action of the guide rod 345. When the drive arm 347 moves, it will move in the rotating groove 344. The thrust of the drive arm 347 moving in the rotating groove 344 will drive the rotating shaft 343 to rotate, thereby causing the mounting base 31 and the current transformer 1 to deflect at a certain angle, increasing the flexibility of installation.

[0051] A method for installing a quick-assembly and disassembly current transformer mounting device includes the following steps:

[0052] Step 1: Before installing the current transformer 1, fix the mounting mechanism 3 in a suitable position with bolts and double-hole connecting plates. Insert the two single-hole plug-in seats 2 into the two plug-in posts 32 respectively. Under the pushing of the single-hole plug-in seats 2, the two locking heads 37 rotate into the concave rotating seat 36. After the single-hole plug-in seats 2 are attached to the mounting base 31, the locking heads 37 reset and press against the front of the single-hole plug-in seats 2 to complete the installation of the current transformer 1.

[0053] Step 2: Press down on the two connecting pieces 312 respectively. The insert rod 311 will drive the fixing piece 313 and the drive rod 315 to slide. The drive rod 315 will drive the concave rotating seat 36 and the locking head 37 to deflect into the inner groove 34, releasing the locking head 37 from limiting the single hole plug seat 2. At the same time, push the H-shaped plate 323 so that the triangular block 319 drives the push-pull rod 321 to push the push plate 318. The push plate 318 pushes the single hole plug seat 2 out of the plug post 32 to complete the disassembly.

[0054] Step 3: Pull the mounting base 31, and the fixed base 340 will pull the telescopic rod 328 and the slide 327 to slide. At this time, the telescopic rod 328 will deflect away from the connecting base 324, thereby pushing the fixed base 340 and the mounting base 31 away from the connecting base 324, so that the current transformer 1 can be moved out of the cramped space, making it easier to disassemble and assemble the current transformer 1.

[0055] Step 4: Rotate the anti-slip knob 348 to drive the lead screw 346 to rotate. The drive arm 347 moves along the lead screw 346 under the action of the guide rod 345. The drive arm 347 drives the rotating shaft 343 to rotate under the thrust of moving in the rotating groove 344, thereby causing the mounting base 31 and the current transformer 1 to deflect at a certain angle, increasing the flexibility during installation.

After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

A method for installing a quick-assembly and disassembly current transformer mounting device, the method being applied to the mounting device as described in claim 5, comprising the following steps: Step 1: Before installing the current transformer (1), fix the installation mechanism (3) in a suitable position with bolts and double-hole connecting plates. Insert the two single-hole plug-in seats (2) into the two plug-in posts (32) respectively. The two locking heads (37) rotate into the concave rotating seat (36) under the pushing of the single-hole plug-in seats (2). After the single-hole plug-in seats (2) are attached to the mounting seat (31), the locking heads (37) reset and press against the front of the single-hole plug-in seats (2) to complete the installation of the current transformer (1). Step 2: Press down on the two connecting pieces (312) respectively. The insert rod (311) will drive the fixing piece (313) and the drive rod (315) to slide. The drive rod (315) will drive the concave rotating seat (36) and the locking head (37) to deflect into the inner groove (34), releasing the locking head (37) from the single hole plug-in seat (2).

Step 4: Rotate the anti-slip knob (348) to drive the lead screw (346) to rotate. The drive arm (347) moves along the lead screw (346) under the action of the guide rod (345). The drive arm (347) drives the rotating shaft (343) to rotate under the thrust of moving in the rotating groove (344). This causes the mounting base (31) and the current transformer (1) to deflect at a certain angle, increasing the flexibility during installation.
