[0023] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] With reference to Figures 1 to 3 The utility model provides an embodiment: three -dimensional volume iron core oil immersed transformer, including body 1, the body 1 here is transformer body, it is mainly based on electromagnetic induction law. When primary side winding is connected to ac power supply, alternating magnetic field will be produced, the magnetic field passes through the iron core of the equilateral triangle three -dimensional structure that is spliced by three same rectangular single frame iron core, due to the high magnetic permeability of the iron core, the magnetic circuit loss is small. This alternating magnetic field induces electromotive force in secondary winding, thereby realizing voltage transformation. Meanwhile, the iron core and winding are immersed in insulating oil, the insulating oil not only plays an electrical insulation role, but also can transfer the heat generated during the operation of the transformer from the coil to the radiator, to ensure that the transformer works in the normal operating temperature range. The top end of body 1 is fixedly connected with a plurality of connectors 2, and the connector 2 is used for connecting external electrical equipment, and the connector 2 here is the connecting port of the above-mentioned side winding for connecting external electrical equipment.

[0025] The side, away from the connector 2, of the body 1 is fixedly connected with two support steels 3, the shape of the support steel 3 is U type, the U type design of the support steel 3 here reduces the cost while ensuring the support strength of itself, and the side, away from the body 1, of the two support steels 3 is detachably connected with a mounting plate 4, the mounting plate 4 here is used for fixing the transformer, the inner wall of the support steel 3 is slidably connected with two slide columns 5, the outer portion of the slide column 5 is slidably connected to the inner wall of the mounting plate 4, the support steel 3 here provides a stable sliding space for the slide column 5, one end of the slide column 5 is fixedly connected with a knob 6, pulling or rotating the knob 6 here can drive the slide column 5 to move in the same way, the other end of the slide column 5 is fixedly connected with a clamping block 7, the outer portion of the clamping block 7 is slidably connected to the inner wall of the mounting plate 4, a plurality of clamping grooves 8 are formed in the inner portion of the mounting plate 4, the clamping block 7 and the clamping groove 8 are in clamping relationship, the shape of the clamping groove 8 here is similar to a circle with three fourths cut off, only one fourth is reserved, so that the clamping block 7 can be clamped after being inserted into the inner wall of the mounting plate 4 and being rotated about 90 degrees.

[0026] The outer part of the sliding column 5 is connected with a gasket I 9, one side of the gasket I 9 is in contact with the inner wall of the support steel 3, the outer part of the sliding column 5 is fixedly connected with a gasket II 10, one side of the gasket II 10 is in contact with the inner wall of the support steel 3, the outer part of the sliding column 5 is sleeved with a spring 11, the spring 11 is in a compressed state and will release a counterforce to both ends, and the gasket I 9 and the gasket II 10 can provide stable support for the spring 11, so that the sliding column 5 further extrudes the spring 11 when descending, so that the spring 11 generates a stronger counterforce, ensuring the clamping state of the clamping block 7 and the clamping groove 8, preventing accidental disengagement, one end of the spring 11 is fixedly connected to one side of the gasket I 9, and the other end of the spring 11 is fixedly connected to one side of the gasket II 10.

[0027] Working principle: When the primary winding is connected to an AC power source, an alternating magnetic field is generated. This alternating magnetic field passes through the iron core of the equilateral triangular three-dimensional structure formed by splicing three identical rectangular single-frame iron cores. Due to the high magnetic permeability of the iron core, the magnetic circuit loss is minimized. This alternating magnetic field induces an electromotive force in the secondary winding, thereby achieving voltage transformation.

[0028] At the same time, the iron core and winding are immersed in insulating oil. The insulating oil not only plays an electrical insulation role, but also transfers the heat generated during the operation of the transformer from the coil to the heat sink, ensuring that the transformer operates within the normal operating temperature range.

[0029] In order to ensure the stability and safety of the device, the device also includes multiple connectors for connecting external electrical equipment. These connectors provide stable electrical connection ports, allowing the device to be reliably connected to external equipment.

[0030] In addition, the device is equipped with support steel and mounting plates to provide additional support and fixing functions. The support steel is designed in a U-shaped form, which not only ensures its support strength, but also reduces costs.

[0031] When it is necessary to disassemble the machine body 1 for routine maintenance, the knob 6 can be pressed first to extrude the sliding column 5 and the clamping block 7, so that the clamping block 7 is movable inside the clamping groove 8, and then the knob 6 is turned clockwise by about 90 degrees. Since the spring 11 is originally in a compressed state, when the knob 6 is pressed, the gasket I 9 and the gasket II 10 exert a force on the spring 11, making it contract more obviously, and the resulting counterforce is also stronger. At this time, the hand is released, and the strong counterforce of the spring 11 drives the sliding column 5 and the clamping block 7 to move upward rapidly, so that the clamping block 7 is disengaged from the clamping groove 8, thereby disassembling the machine body 1 from the top end of the mounting plate 4.

[0032] After finishing, only need to align the card block 7 when installing the slot of the card slot 8 opened at the top end of the mounting plate 4, then turn the knob 6, make it can smoothly put into the inside of the card slot 8, then counterclockwise rotate about 90 degrees, make that the card block 7 and the card slot 8 re-form the card engagement relationship can be.

[0033] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
