Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to an auxiliary component for testing current transformers. Background Technology

[0002] An instrument transformer is a device that can convert high voltage to low voltage and large current to small current. It is used in measurement or protection systems to standardize and miniaturize measuring instruments, protection devices, and automatic control equipment. At the same time, instrument transformers can also be used to isolate high voltage to ensure the safety of personnel and equipment.

[0003] Comparing with the published patent number CN222748698U, a current transformer testing auxiliary mechanism is disclosed, which relates to the technical field of current transformer testing auxiliary devices. It includes a testing platform, on which an auxiliary testing mechanism is set. The auxiliary testing mechanism includes a circulating connector connection unit and multiple sets of component transmission units. The circulating connector connection unit includes a mounting plate, on which symmetrically distributed push slides are provided. An adjustment slide groove is provided in the push slide, and an extension slider is provided in the adjustment slide groove. A conductive plug seat is provided on the extension slider, and a conductive plug port is provided in the middle of the conductive plug seat.

[0004] Although the above solution allows for quick connection between the current transformer and the conductive plug by changing the shape of the conductive plug to correspond to different current transformers, thus enabling rapid testing of a large number of current transformers, this method requires changing the conductive plug when testing current transformers with different plugs. This presents certain inconveniences when testing a large number of current transformers with different plugs, resulting in relatively low efficiency in the current transformer testing operation. Utility Model Content

[0005] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to solve the problems raised in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary component for testing current transformers, comprising a testing platform and a support platform. A testing base is slidably mounted on the inner side of the testing platform. A first limiting groove is formed on the surface of the testing base, and a second limiting groove is formed on the surface of the testing platform. A hydraulic telescopic rod is welded and mounted on the surface of the support platform. A conductive plug assembly plate is fixedly mounted on the lower end of the hydraulic telescopic rod. An extension platform and a material distribution platform are welded and mounted on the surface of the testing platform, with the material distribution platform located below the extension platform.

[0007] Preferably, a limiting rectangular plate is slidably installed on the inner side of the detection platform, and a limiting slide rod is welded to the surface of the limiting rectangular plate. The lower end of the limiting slide rod is slidably installed on the inner side of the detection platform.

[0008] Preferably, the surface of the limiting rectangular plate is composed of a combination of a rectangular surface and an inclined surface.

[0009] Preferably, the surface of the extension platform is provided with a discharge groove, and the shape of the extension platform is L-shaped.

[0010] Preferably, an extension rod is welded to the surface of the testing platform, and the end of the extension rod away from the testing platform is welded to the surface of the support platform, and the surface of the support platform is provided with a placement groove.

[0011] Preferably, a limiting guide rod is welded to the surface of the extension platform, and the surface of the limiting guide rod is slidably mounted inside the detection base.

[0012] Preferably, the surface of the limiting slide bar is slidably fitted with an elastic component, and the two ends of the elastic component abut against the surfaces of the limiting rectangular plate and the detection platform, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) The auxiliary component for transformer testing allows the operator to remove defective transformers individually while the testing base is still above the testing platform. Then, the testing base is moved to the extension platform, and the qualified transformers fall through the unloading groove on the extension platform to the distribution platform for collection. When testing multiple transformers with different plugs, the auxiliary component can be simultaneously positioned and tested. This greatly improves the cumbersome process of replacing components and testing transformers with different plugs, thus improving the efficiency of testing multiple transformers. It also ensures the convenience of positioning and automatic detachment of multiple transformers, thereby improving the efficiency of transformer testing.

[0014] (2) The auxiliary component for testing current transformers reaches a predetermined position through the testing base and testing platform. The testing base no longer obstructs the limiting rectangular plate. At this time, the limiting rectangular plate is pushed back by the elastic performance of the compressed elastic component, so that the inclined surface of the limiting rectangular plate abuts against the testing base through the testing base. This method not only ensures that the testing base and testing platform have convenient adjustment and movement effects when docking, but also ensures the smoothness of the adjustment and positioning of the testing base through the cooperation of the inclined surface and rectangular surface of the limiting rectangular plate.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] Please see Figure 1-4This utility model provides a technical solution: an auxiliary component for testing current transformers, including a testing platform 1, an extension rod 2 welded to the surface of the testing platform 1, a support platform 3 welded to the end of the extension rod 2 away from the testing platform 1, and a placement groove 4 provided on the surface of the support platform 3, where the relevant current transformer can be temporarily placed.

[0022] Furthermore, a testing base 5 is slidably installed on the inner side of the testing platform 1. A first limiting groove 6 is opened on the surface of the testing base 5, and a second limiting groove 7 is opened on the surface of the testing platform 1. When testing multiple sets of current transformers, it is only necessary to fit the multiple sets of current transformers into the inner wall of the first limiting groove 6 on the testing base 5 in sequence. The testing platform 1 limits and blocks the first limiting groove 6 on the testing base 5, so the current transformer can be stably placed at the first limiting groove 6 on the testing base 5. Then, after controlling the testing base 5 to enter the predetermined position inside the testing platform 1, the first limiting groove 6 on the testing base 5 and the second limiting groove 7 on the testing platform 1 are aligned and matched. At this time, the current transformer will be effectively positioned and placed at the testing platform 1.

[0023] Furthermore, a limiting rectangular plate 8 is slidably installed on the inner side of the detection platform 1, and a limiting slide rod 9 is welded and installed on the surface of the limiting rectangular plate 8. The lower end of the limiting slide rod 9 is slidably installed on the inner side of the detection platform 1, and an elastic component 10 is slidably sleeved on the surface of the limiting slide rod 9. The two ends of the elastic component 10 are respectively abutted and installed on the surfaces of the limiting rectangular plate 8 and the detection platform 1. The surface of the limiting rectangular plate 8 is composed of a rectangular surface and an inclined surface.

[0024] Furthermore, when the detection base 5 and the detection platform 1 are closed and positioned, the detection base 5 pushes the inclined surface of the limiting rectangular plate 8 so that the limiting rectangular plate 8 can be housed inside the detection platform 1 until the detection base 5 and the detection platform 1 reach the predetermined position. At this time, the detection base 5 no longer obstructs the limiting rectangular plate 8. The limiting rectangular plate 8 is then pushed back to its original position by the elasticity of the compressed elastic component 10, so that the inclined surface of the limiting rectangular plate 8 abuts against the detection base 5 through the detection base 5. This method not only ensures that the detection base 5 and the detection platform 1 have convenient adjustment and movement when docking, but also ensures the smoothness of the adjustment and positioning of the detection base 5 through the cooperation of the inclined surface and the rectangular surface of the limiting rectangular plate 8.

[0025] Furthermore, a hydraulic telescopic rod 15 is welded and installed on the surface of the support platform 3. A conductive plug assembly plate 16 is fixedly installed at the lower end of the hydraulic telescopic rod 15. After the current transformer is effectively limited at the detection platform 1 by the detection base 5, the hydraulic telescopic rod 15 works to drive the conductive plug assembly plate 16 to descend. Then, when the hydraulic telescopic rod 15 moves to the predetermined position, the conductive plugs on the conductive plug assembly plate 16 can respectively connect and test with multiple sets of adapted current transformers. The hydraulic telescopic rod 15 and the conductive plug assembly plate 16 are both existing publicly available technologies, and the related power components and electrical components are also publicly available technologies, which will not be described in detail here.

[0026] Furthermore, an extension platform 11 is welded and installed on the surface of the detection platform 1. A limiting guide rod 12 is welded and installed on the surface of the extension platform 11. The limiting guide rod 12 is slidably installed inside the detection base 5. A discharge groove 13 is opened on the surface of the extension platform 11. The extension platform 11 is L-shaped. By limiting the detection base 5 through the limiting guide rod 12, the detection base 5 can have a stable adjustment effect when sliding and adjusting at the detection platform 1. The L-shape of the extension platform 11 can effectively limit the adjustment distance of the detection base 5. When the detection base 5 slides to the predetermined position, the current transformer inside the first limiting groove 6 on the detection base 5 will automatically fall out and be unloaded because the first limiting groove 6 on the detection base 5 is no longer blocked.

[0027] Furthermore, a material distribution platform 14 is welded and installed on the surface of the testing platform 1. The material distribution platform 14 is located below the extension platform 11. By setting the material distribution platform 14 below the extension platform 11, the current transformers that have passed the test and been de-materialized are collected and discharged.

[0028] Working principle: An auxiliary component for testing current transformers. When multiple current transformers need to be tested, the operator places multiple sets of current transformers into the inner wall of the first limiting groove 6 on the testing base 5 in sequence. After adjusting the testing base 5 to align with the testing platform 1, the hydraulic telescopic rod 15 drives the conductive plug assembly plate 16 to descend, allowing the conductive plug assembly plate 16 to align with the positioned current transformers for testing. After the current transformers have completed testing, the testing base 5 separates from the testing platform 1. While the testing base 5 is still above the testing platform 1, the operator can remove the current transformers that fail to meet the quality standards. At this point, the testing base 5 is moved to the extension platform 11, and the current transformers that meet the quality standards fall through the unloading groove 13 on the extension platform 11 to the distribution platform 14 for collection and processing.

[0029] Contents or structures not described in detail in this specification are existing technologies known to those skilled in the art, and therefore will not be elaborated upon further.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
