Description

Technical Field

[0001] This utility model relates to the field of transformer testing technology, and in particular to a transformer testing device. Background Technology

[0002] In recent years, transformers, as an important component of the power system, have been crucial for ensuring the stability and safety of power transmission. With the development of the Internet of Things and big data technologies, the use of intelligent technologies for real-time monitoring of transformers has become a new trend.

[0003] In traditional transformer testing equipment, the transformer is usually fixed manually or by screwing it onto a platform, which takes about 5-10 minutes. Then, external testing instruments are used to test the transformer's values.

[0004] However, fixing the transformer with screws is time-consuming and laborious to disassemble, and cannot be adjusted according to different transformer sizes, resulting in low applicability and reduced work efficiency. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the prior art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where manual bolt fixing is time-consuming, and to propose a transformer testing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A transformer testing device includes a base, a housing on top of the base, a fixed shell fixedly connected to the housing, a bidirectional threaded rod rotatably connected between the inner walls of the two sides of the fixed shell, two sliders threadedly connected to the outer sides of the bidirectional threaded rod, a fixed column fixedly connected to the top of each of the two sliders, an L-shaped clamping block fixedly connected to the top of each of the two fixed columns, a sliding groove opened on the top of the fixed shell, and the two L-shaped clamping blocks sliding within the sliding groove, with a transformer body disposed between the two L-shaped clamping blocks.

[0008] As a further embodiment of this utility model, a step is fixedly connected to one side of the base, and a scissor lift frame is provided inside the base, with one end of the scissor lift frame fixed to the shell.

[0009] As a further embodiment of this utility model, one end of the bidirectional threaded rod passes through the fixed shell and is fixedly connected to a handle, and a nut is threadedly connected to the outer side of the bidirectional threaded rod.

[0010] As a further embodiment of this utility model, a guide rail is fixedly connected between the inner walls of the two sides of the fixed shell, and the two sliders slide within the guide rail.

[0011] As a further embodiment of this utility model, two hinges are fixedly connected to one side of the housing, and a door panel is fixedly connected to one end of each of the two hinges. A handle is fixedly connected to one side of each of the two door panels.

[0012] As a further embodiment of this utility model, the top of one of the door panels is rotatably connected to a movable block via a bearing, and a socket is provided on one side of the movable block and the top of the other door panel, with a plug inserted into the two sockets.

[0013] As a further embodiment of this utility model, anti-slip pads are fixedly connected to one side of each of the two L-shaped clamps, and one side of the anti-slip pads is integrally formed with anti-slip texture.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model is equipped with a bidirectional threaded rod. By setting the bidirectional threaded rod, slider and L-shaped clamps, the bidirectional threaded rod is rotated, and then the two L-shaped clamps slide in opposite directions in the sliding groove, thereby adjusting the distance between the L-shaped clamps and realizing the clamping and loosening of the transformer. This allows for clamping of transformer bodies of different sizes, enhances the applicability of the equipment, and takes about 1 minute, greatly improving efficiency.

[0016] 2. This utility model is equipped with a scissor lift frame. The connection between the scissor lift frame and the housing improves the convenience of inspection. By operating the scissor lift frame, the height position of the housing can be changed, thereby changing the height position of the transformer. This allows for convenient adjustment of the transformer's height and facilitates inspection work for operators.

[0017] 3. This utility model is equipped with a movable block, which, after the door panel is closed, allows the door panel to be fixed by inserting the plug into the hole on the door panel and the movable block. This effectively prevents external factors from interfering with the transformer testing process, while also protecting internal components and increasing the safety of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-4 A transformer testing device includes a base 1, a housing 3 on the top of the base 1, a fixing shell 6 fixed to the housing 3 by bolts, and a sliding groove 15 on the top of the fixing shell 6.

[0025] A bidirectional threaded rod 18 is rotatably connected between the inner walls of the two sides of the fixed shell 6 via an embedded bearing. The bidirectional threaded rod 18 is inclined between the diagonals of the fixed shell 6. The bidirectional threaded rod 18 has a trapezoidal thread structure. Two sliders 19 are threadedly connected to the outer side of the bidirectional threaded rod 18. A fixing post 14 is welded to the top of each slider 19. An L-shaped clamping block 4 is fixed to the top of each fixing post 14 by bolts. Both L-shaped clamping blocks 4 slide in the slide groove 15. An anti-slip pad 20 is glued to one side of each L-shaped clamping block 4. The anti-slip pad 20 has an integral anti-slip texture on one side. The anti-slip pad 20 is made of nitrile rubber material with a Shore hardness of 60±5. The transformer body 5 can be clamped between the two L-shaped clamping blocks 4. During use, it can effectively prevent the transformer body 5 from sliding during the clamping process and ensure the stability of the transformer body 5 during the testing process.

[0026] One end of the bidirectional threaded rod 18 passes through the fixed shell 6 and is welded with a handle 11. The outer thread of the bidirectional threaded rod 18 is connected with a nut 16. When in use, the bidirectional threaded rod 18 can be rotated through the handle 11, which is convenient for the operator to operate and increases the convenience of the device. The bidirectional threaded rod 18 can be locked through the nut 16 to prevent it from shifting during use.

[0027] The inner walls of the two sides of the fixed shell 6 are fixed with guide rails 17 by bolts, and the two sliders 19 slide in the guide rails 17. The guide rails 17 can guide the sliders 19 and increase the stability of the sliders 19 when sliding.

[0028] In use, the transformer body 5 is placed on the fixed shell 6, and the bidirectional threaded rod 18 is rotated. The rotation of the bidirectional threaded rod 18 causes the two sliders 19 to move towards or away from each other along the guide rail 17, thereby driving the two L-shaped clamps 4 to slide in the slide groove 15, thereby clamping or releasing the transformer body 5. Then, external testing instruments are connected to the transformer body 5, so that transformers of different sizes can be clamped, enhancing the applicability of the equipment.

[0029] In this utility model, a step 8 is fixed to one side of the base 1 by bolts. A scissor lift frame 12 is provided inside the base 1. The scissor lift frame 12 is powered by a matching hydraulic drive device. The hydraulic drive device is installed inside the base 1, and one end of the scissor lift frame 12 is fixed to the housing 3. When in use, the scissor lift frame 12 is activated, so that the housing 3 together with the transformer body 5 rises or falls to a suitable position, thereby changing the height position of the transformer, making it convenient to adjust the height of the transformer, and facilitating the operator to carry out inspection work.

[0030] In particular, two hinges 7 are fixed to one side of the housing 3 by bolts, and a door panel 2 is fixed to one end of each hinge 7 by bolts. A handle 11 is fixed to one side of each door panel 2 by bolts.

[0031] One of the door panels 2 has a movable block 9 rotatably connected to its top via a bearing. Both the side of the movable block 9 and the top of the other door panel 2 have insertion holes, into which insert blocks 10 are inserted. In use, after the insert blocks 10 are pulled out of the two insertion holes, the door panel 2 can be opened through the handle 11. The two door panels 2 can be opened by rotating around the hinge 7, thereby allowing the door panels 2 to be closed or opened. The cooperation between the door panels 2 and the housing 3 protects the device inside the housing 3, increasing the safety of the device.

[0032] Working principle: When monitoring the transformer is required, after pulling out the plug 10 from the two sockets, the door panel 2 can be opened by the handle 11. The two door panels 2 can be opened by rotating around the hinge 7. The transformer body 5 is placed on the fixed shell 6. By rotating the handle 11, the bidirectional threaded rod 18 is rotated. The rotation of the bidirectional threaded rod 18 causes the two sliders 19 to move towards or away from each other along the guide rail 17, thereby driving the two L-shaped clamps 4 to slide in the slide groove 15, realizing the clamping or loosening of the transformer body 5. Then, the testing instrument is connected to the transformer body 5. Subsequently, if it is necessary to adjust the height of the transformer body 5, the scissor lift frame 12 can be operated to raise or lower the shell 3 together with the transformer body 5 to a suitable position, thereby enabling the clamping of transformers of different sizes and enhancing the applicability of the equipment.

[0033] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
