Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary technology for power supply equipment, and in particular to an automatic detection platform for power metering transformers. Background Technology
[0002] Voltage transformers are similar to transformers in that they are instruments used to transform voltage. However, transformers transform voltage to facilitate the transmission of electrical energy, so their capacity is very large, usually measured in kilovolt-amperes or megavolt-amperes. On the other hand, voltage transformers transform voltage primarily to power measuring instruments and relay protection devices, to measure the voltage, power, and energy of a line, or to protect valuable equipment, motors, and transformers in the event of a line fault. Therefore, voltage transformers have a very small capacity, typically only a few volt-amperes or tens of volt-amperes.
[0003] A search of existing Chinese patent technology reveals a "self-lifting power testing platform device" with publication number "CN212646967U". This device eliminates the need for disassembling, reassembling, and calibrating current transformers during use, maintaining the high reliability of the integrated current transformers. However, during testing, the device requires sequential placement and testing of the current transformers, which means that subsequent operations cannot be performed if a current transformer is not being tested, thus reducing the testing efficiency of the current transformers. Utility Model Content
[0004] Therefore, it is necessary to address the issue that during testing, current transformers need to be placed and tested sequentially, which prevents subsequent operations from being performed if a transformer is not being tested, thus reducing the testing efficiency. To address this, an automatic testing platform for power metering current transformers is provided, comprising: a base, on which a testing instrument is fixedly connected; and a platform mechanism mounted on the upper end of the base, located inside the testing instrument. The platform mechanism includes a guide mechanism mounted on the upper end of the base, a rotating component located inside the guide mechanism, and multiple positioning components located on the upper end of the rotating component.
[0005] In one embodiment, the rotating assembly includes a thrust bearing fixedly connected to the upper end of the base. A rotating platform is fixedly connected to the upper end of the thrust bearing. A servo motor fixedly connected to the upper end of the base is disposed inside the rotating platform. A connecting plate is fixedly connected to the output shaft of the servo motor. The surface of the connecting plate is fixedly connected to the inner wall of the rotating platform. Multiple sector plates are fixedly connected to the surface of the rotating platform. A mounting seat is slidably connected to the upper end of each sector plate. A sliding frame is fixedly connected to the lower end of each sector plate. A sliding seat is slidably connected to the inner wall of the sliding frame. The servo motor drives the rotating platform to rotate via the connecting plate. The lower end of the rotating platform maintains stable rotation via the thrust bearing, so that when the sector plates move, the sliding frame drives the sliding seat to move accordingly.
[0006] In one embodiment, the positioning component includes two side plates fixedly connected to the inside of the mounting base. Two round tubes are fixedly connected to the side plates away from the mounting base. An abutment post is provided inside the round tube. Two round holes are opened on one side of the side plates. The inner wall of the round holes is slidably connected to the inner wall of the abutment post. An abutment plate is fixedly connected to the end of the abutment post away from the round tube. An adhesive strip is fixedly connected to the side of the abutment plate away from the side plates.
[0007] In one embodiment, the guiding mechanism includes a guide frame disposed on the upper end of the base, with a plurality of support rods fixedly connected to the lower end of the guide frame, and the lower ends of the support rods fixedly connected to the upper end of the base. Rolling wheels are located on the inner and outer sides of the guide frame, wherein the cross-section of the guide frame is pear-shaped. When the rolling wheels follow the arc-shaped plate in an arc-shaped motion, the guide frame abuts against the rolling wheels.
[0008] In one embodiment, the upper end of the sliding seat is fixedly connected to the lower end of the adjacent mounting seat, and two rollers are fixedly connected to the lower end of the sliding seat.
[0009] In one embodiment, a sliding block is fixedly connected to the end of the abutting post away from the abutting post, and the sliding block is slidably connected to the inner wall of the circular tube.
[0010] In one embodiment, a spring is fixedly connected to the inner wall of the circular tube, and the other end of the spring is fixedly connected to the surface of the sliding block. The elastic potential energy of the spring causes the sliding block to move synchronously with the abutment plate via the abutment post, thus causing the adhesive strip to adhere to the surface of the workpiece.
[0011] Beneficial effects
[0012] 1. The above-mentioned automatic testing platform for power metering transformers, through the cooperation of the rotating component and the guiding mechanism, enables the power transformers to be automatically moved to the bottom of the testing instrument after the operator places them during the transportation process. The guiding mechanism ensures that the testing position matches the position of the power transformer. Furthermore, multiple transformers can be placed and tested sequentially during the testing operation, thereby improving the testing efficiency of the transformers.
[0013] 2. With the help of the rotating and positioning components, the power transformer can be quickly placed inside the mounting base. At this time, two abutments are provided to clamp the power transformer. The abutment post and the round hole ensure a good clamping effect on the power transformer. The adhesive strip ensures a tight fit while clamping the power transformer. Attached Figure Description

[0026] The following is combined Figures 1-4This invention describes an automatic testing platform for power metering transformers.
[0027] In one embodiment, an automatic testing platform for power metering transformers includes: a base 1, with a tester 2 fixedly connected to the surface of the base 1; and a platform mechanism 3, which is installed on the upper end of the base 1 and disposed inside the tester 2. The platform mechanism 3 includes a guide mechanism 33 installed on the upper end of the base 1, a rotating component 31 disposed inside the guide mechanism 33, the rotating component 31 being installed on the upper end of the base 1, and a plurality of positioning components 32 disposed on the upper end of the rotating component 31.
[0028] It should be noted that: existing detectors generally use mechanical positioning devices and lifting components to achieve automatic alignment of voltage transformer pins and detection contacts, and complete multi-dimensional spatial precise positioning through a drive mechanism to improve detection efficiency; some platforms integrate image recognition technology to monitor the equipment status in real time through high-definition cameras;
[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the rotating assembly 31 includes a thrust bearing 311 fixedly connected to the upper end of the base 1. A rotating platform 313 is fixedly connected to the upper end of the thrust bearing 311. A servo motor 312 fixedly connected to the upper end of the base 1 is provided on the inner side of the rotating platform 313. A connecting plate 314 is fixedly connected to the output shaft of the servo motor 312. The surface of the connecting plate 314 is fixedly connected to the inner wall of the rotating platform 313. A plurality of sector plates 315 are fixedly connected to the surface of the rotating platform 313. A mounting seat 319 is slidably connected to the upper end of the sector plate 315.
[0030] A sliding frame 316 is fixedly connected to the lower end of the sector plate 315. A sliding seat 317 is slidably connected to the inner wall of the sliding frame 316. The upper end of the sliding seat 317 is fixedly connected to the lower end of the adjacent mounting seat 319. Two rolling wheels 318 are fixedly connected to the lower end of the sliding seat 317. The guide mechanism 33 includes a guide frame 331 disposed on the upper end of the base 1. A plurality of support rods 332 are fixedly connected to the lower end of the guide frame 331. The lower ends of the support rods 332 are fixedly connected to the upper end of the base 1.
[0031] In this embodiment, the device drives the servo motor 312 to drive the rotating table 313 to rotate via the connecting plate 314. The lower end of the rotating table 313 maintains a stable rotation via the thrust bearing 311. When the sector plate 315 moves, the sliding frame 316 drives the sliding seat 317 to move accordingly. The sliding seat 317 drives two rolling wheels 318 to move synchronously in an arc. The two rolling wheels 318 are located on the inner and outer sides of the guide frame 331. The cross-section of the guide frame 331 is pear-shaped. When the rolling wheels 318 follow the sector plate 315 in an arc, the guide frame 331 abuts against the rolling wheels 318, which allows the rolling wheels 318 to translate relative to the sliding frame 316. This allows the workpiece to be placed on the mounting seat 319 and gradually moved to the bottom of the detector 2 for detection. After the detection is completed, the workpiece can be reset.
[0032] like Figure 1 , Figure 2 and Figure 4 As shown, the positioning component 32 includes two side plates 321 fixedly connected to the inner side of the mounting base 319. Two round tubes 322 are fixedly connected to the side of the side plate 321 away from the mounting base 319. An abutment post 323 is provided inside the round tube 322. Two round holes 324 are opened on one side of the side plate 321. The inner wall of the round hole 324 is slidably connected to the inner wall of the abutment post 323. An abutment plate 325 is fixedly connected to the end of the abutment post 323 away from the round tube 322. An adhesive strip 326 is fixedly connected to the side of the abutment plate 325 away from the side plate 321.
[0033] A sliding block 327 is fixedly connected to one end of the abutment post 323 away from the abutment post 323. The sliding block 327 is slidably connected to the inner wall of the round tube 322. A spring 328 is fixedly connected to the inner wall of the round tube 322. The other end of the spring 328 is fixedly connected to the surface of the sliding block 327.
[0034] In this embodiment, the device uses two abutment plates 325 to form an auxiliary clamp for the current transformer, ensuring that the current transformer does not undergo large displacement when moving with the mounting base 319. Furthermore, the two adhesive strips 326 bring the current transformer closer together to form a relatively good squeezing effect. During operation, the operator can directly place the current transformer between the two abutment plates 325. Through the elastic potential energy of the spring 328, the sliding block 327 drives the abutment plates 325 to move synchronously through the abutment column 323, so that the adhesive strips 326 adhere to the surface of the workpiece, providing a buffering effect during the movement of the workpiece.
[0035] Working principle: During operation, the operator places the power transformer directly between the two abutment plates 325. Through the elastic potential energy of the spring 328, the sliding block 327 drives the abutment plate 325 to move synchronously through the abutment column 323. The rubber strip 326 adheres to the surface of the workpiece, providing a buffer effect during the movement of the workpiece. The drive servo motor 312 drives the rotating table 313 to rotate through the connecting plate 314. When the sector plate 315 moves, it drives the sliding seat 317 to move along through the sliding frame 316. The sliding seat 317 drives the two rolling wheels 318 to move synchronously in an arc. The two rolling wheels 318 are located on the inner and outer sides of the guide frame 331. The cross-section of the guide frame 331 is pear-shaped. When the rolling wheels 318 follow the arc movement of the sector plate 315, the guide frame 331 abuts against the rolling wheels 318 and moves horizontally under the sliding frame 316. The workpiece is placed on the mounting seat 319 and gradually moves to the bottom of the detector 2 for testing. After the test is completed, the workpiece is reset.
[0036] It should be noted that the detector 2 and servo motor 312 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the detector 2 and servo motor 312 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.
[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0038] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
