[0002] Test transformers are essential testing equipment for the inspection and preventive testing of power equipment.

[0003] While existing gas-filled test transformers have solved the problems of large size, heavy weight, and high maintenance costs of traditional hydraulic test transformers, the gas-filled test transformers and their control cabinets are usually set up separately. This results in them occupying a lot of vehicle space during transportation to the construction site, increasing the difficulty of transportation and on-site setup, and making them inconvenient to carry.

[0004] Therefore, a solution is needed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art by proposing a portable gas-filled test transformer.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a portable gas-filled test transformer, comprising a transformer body, a high-voltage system and a control cabinet, wherein the transformer body and the high-voltage system are detachably connected via a bushing flange, a plurality of locking blocks are evenly distributed on the top of the control cabinet, a protective base is fixedly provided on the bottom of the transformer body, and the protective base is provided with locking slots corresponding to the positions of the locking blocks, and a locking assembly is provided between the locking blocks and the locking slots.

[0007] The present invention is further configured such that: the sidewalls of the card block and the card slot are provided with slides; the carding assembly includes a magnet and a metal ball that magnetically attracts the magnet; the magnet is embedded in the slide of the card block; the metal ball is slidably disposed in the slide of the card slot; and a reset member is provided for the sliding of the metal ball and the card slot.

[0008] The present invention is further configured such that: the reset component is a tension spring, and the tension spring is fixedly connected to the metal ball and the bottom wall of the slide.

[0009] The present invention is further configured such that: the control cabinet is provided with a storage cabinet for placing the high-voltage system, and the storage cabinet is provided with an openable and closable cabinet door.

[0010] The present invention is further configured such that: the transformer body is provided with a ring handle for easy handling, and the ring handle is provided with an insulating rubber sleeve.

[0011] The present invention is further configured such that: each of the four corners of the bottom of the control cabinet is provided with a caster wheel, and each caster wheel is provided with a braking device.

[0012] In summary, this utility model has the following beneficial effects: connecting the transformer body and the control cabinet together through a card block, a card slot, and a card-connecting assembly reduces the total floor space occupied by both and facilitates the overall carrying of the equipment.

[0018] 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. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present 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 the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] A portable gas-filled test transformer, such as Figures 1-4 As shown, it includes a transformer body 1, a high-voltage system 2 and a control cabinet 3. The transformer body 1 and the high-voltage system 2 are connected by a bushing flange 4. Several locking blocks 6 are evenly distributed on the top of the control cabinet 3. A protective base 5 is fixedly installed at the bottom of the transformer body 1. The protective base 5 is provided with a slot 7 corresponding to the position of several locking blocks 6. A locking assembly is provided between the locking blocks 6 and the slot 7.

[0020] Specifically, the sidewalls of the card block 6 and the card slot 7 that are in contact with each other are provided with slides 8. The carding assembly includes a magnet 9 and a metal ball 10 that is magnetically attracted to the magnet 9. The magnet 9 is embedded in the slide 8 at the card block 6, and the metal ball 10 is slidably disposed in the slide 8 at the card slot 7. The metal ball 10 and the slide at the card slot 7 are provided with a reset component. Specifically, the reset component is a tension spring 11, which is fixedly connected to the metal ball 10 and the bottom wall of the slide 8 respectively.

[0021] During transport, the transformer body 1 and the control cabinet 3 are connected together by the card block 6, the card slot 7 and the card connection assembly, which reduces the total floor space occupied by both and facilitates the overall transport of the equipment.

[0022] like Figures 1-4 The control cabinet 3 shown is equipped with a storage cabinet 12 for placing the high-voltage system 2. The storage cabinet 12 is equipped with an openable cabinet door 13. During transportation, the high-voltage system 2 can be disassembled and placed in the storage cabinet 12, reducing the overall height of the equipment and further optimizing the carrying of the equipment.
