[0002] A double autotransformer is a special transformer with two inductively coupled coils and two magnetic cores. This transformer can achieve two different voltage conversions through two independent coils. Double autotransformers are usually used in some special circuits, such as power amplifiers and communication equipment.

[0026] Example

[0027] Reference Figure 1-Figure 5 The utility model provides a technical solution: a double autocoupler double-device transformer, including a shell 1 and a protective mechanism 3, a coil 2 is installed inside the shell 1, the protective mechanism 3 includes an insulating plate 31, a mounting frame 311 is installed inside the shell 1, the inside of the mounting frame 311 is set to be hollow and penetrates the outer surface of the mounting frame 311, an insulating plate 31 is installed inside the mounting frame 311, an insulating disk 32 is arranged on one side of the mounting frame 311, the insulating disk 32 is sleeved on a round rod 321, a plastic support seat 33 is fixedly installed inside the mounting frame 311, and a mounting hole 331 is opened on the plastic support seat 33.

[0028] In a preferred embodiment, an insulator 4 is installed on the top of the shell 1. There are several insulators 4, which are evenly arranged on the top of the shell 1. By installing the insulator 4 on the top of the shell 1, it is convenient to wind the cable around the insulator 4, so as to ensure stable voltage transmission and prevent damage to the transformer.

[0029] In a preferred embodiment, two mounting frames 311 are provided and are respectively installed inside the shell 1. An insulating plate 31 is installed inside each of the two mounting frames 311. The top of the mounting frame 311 is set to be open. In order to improve the insulation effect, the device is provided with two mounting frames 311. An insulating plate 31 is installed inside each mounting frame 311, and there is a certain distance between the two mounting frames 311, so as to ensure the isolation effect of the coil 2 and prevent the two coils 2 from having an electrical short circuit during operation.

[0030] In a preferred embodiment, the two ends of the round rod 321 are respectively fixedly connected to the two mounting frames 311 for mounting the insulating disk 32. Two insulating disks 32 are installed on the round rod 321. In actual use, in order to prevent the two mounting frames 311 from still having current, an insulating disk 32 is installed between the two mounting frames 311. Through the cooperation between the insulating disk 32 and the insulating plate 31, the current can be prevented from changing the original path, thereby ensuring that the transformer can be used normally.

[0031] In order to ensure that the mounting frame 311 can be stably installed inside the shell 1, a mounting plate 5 is fixedly installed at the bottom of the shell 1. A threaded hole 6 is opened on the upper surface of the mounting plate 5. The mounting plate 5 is installed at the inner bottom position of the shell 1 and is installed on the shell 1 by bolts, thereby ensuring the stable use of the mounting frame 311 and the stable use of the insulating plate 31.

[0032] The mounting frame 311 is positioned for stable use, and the insulating plate 31 is also positioned for stable use. Therefore, a positioning mechanism 7 is also installed inside the shell 1. The positioning mechanism 7 includes a connecting rod 71, a universal coupling 72, an extrusion rod 73 and a spring 74. The connecting rod 71 is installed on the round rod 321. The universal coupling 72 is rotatably installed on one end of the connecting rod 71. The universal coupling 72 is rotatably connected to the rectangular block 8. A groove is opened on one side of the rectangular block 8. A spring 74 is installed inside the groove. One end of the spring 74 is fixedly connected to the extrusion rod 73. The extrusion rod 73 is used to extrude and position the insulating plate 31.

[0033] The insulating plate 31 is placed inside the mounting frame 311, and then the rectangular block 8 is rotated to move the squeezing rod 73 to a position corresponding to the insulating plate 31. At the same time, under the action of the spring 74, the squeezing rod 73 can squeeze the insulating plate 31, so that the insulating plate 31 can be stably installed inside the mounting frame 311, so that the insulating plate 31 can be stably used. In order to prevent the connecting rod 71 from hindering the rotation of the rectangular block 8, a universal coupling 72 is installed between the rectangular block 8 and the connecting rod 71 to ensure that the rectangular block 8 can rotate normally, thereby controlling the insulating plate 31 to be stably used.

[0034] Specifically, the working process or working principle of a drone testing platform is as follows: two coils 2 are installed inside a double autotransformer, and the two coils 2 are set to be adjacent to each other. In actual use, due to the close distance between the two coils 2, the current bypasses the original circuit and easily causes an electrical short circuit, thereby damaging the transformer and affecting the normal use of the transformer. Therefore, this device is designed to solve this problem.

[0035] Since two coils 2 are installed in the device and the two coils 2 are relatively close to each other, an insulating plate 31 is installed between the two coils 2 to ensure that the device can be used normally. By placing the insulating plate 31 into the interior of the mounting frame 311 through the device, the outer side surface and the top of the mounting frame 311 are respectively set as openings. Therefore, when the insulating plate 31 is installed in the interior of the mounting frame 311, the insulating plate 31 will be exposed so as to insulate the two coils 2 and prevent the current generated by the two coils 2 when working from bypassing the original circuit and easily causing an electrical short circuit.

[0036] In order to improve the use effect, an insulating disk 32 is also installed between the two mounting frames 311 to ensure that the coil 2 can be used normally and prevent electrical short circuits. Since the insulating plate 31 is placed inside the mounting frame 311 for use, in order to ensure that the insulating plate 31 can be used stably, after the insulating plate 31 is placed inside the mounting frame 311, the rectangular block 8 can be rotated. Since a universal joint 72 is installed on the rectangular block 8, the rotation of the rectangular block 8 will not be hindered by the connecting rod 71. The extrusion rod 73 is moved to the position corresponding to the insulating plate 31, and the extrusion rod 73 is pushed by the spring 74 to only press against the insulating plate 31, so that the insulating plate 31 can be tightly attached to the inner wall of the mounting frame 31, so that the insulating plate 31 is stably installed inside the mounting frame 311, and the insulating plate 31 is stably used.

[0037] The insulating plate 31 is affected by various factors such as electric field, humidity and heat during long-term use, which may cause the performance of the insulating plate 31 to deteriorate, so the insulating plate 31 needs to be replaced regularly. At this time, the shell 1 is disassembled, and then the rectangular block 8 is controlled to rotate to disengage the extrusion rod 73 from the insulating plate 31, and then the insulating plate 31 is taken out from the top of the mounting frame 311, which is convenient for replacing the insulating plate 31 to meet the needs of use.
