Description

Technical Field

[0001] The invention belongs to the technical field of transformers, and in particular relates to an amorphous alloy transformer. Background Art

[0002] An amorphous alloy transformer is a transformer that uses an amorphous alloy material as its core. This type of transformer has a high magnetic permeability and low loss, so it has high efficiency, low operating costs, and low noise. It is currently widely used in power systems in industrial areas, commercial areas, residential areas, and other places.

[0003] A winding is sleeved on the iron core of the transformer, and the winding is connected to the lead wire that passes through the transformer. In order to protect and position the lead wire, a sleeve needs to be provided on the outside of the lead wire. In actual use, in order to be able to replace the sleeve when it is damaged, a presser foot is usually detachably installed around the sleeve. The end of the presser foot contacts the sleeve to press and fix it. After the presser foot is removed, the sleeve can be pulled out.

[0004] In actual use, in order to ensure that the sleeve is pressed and fixed more stably, multiple presser feet are provided around each sleeve. This means that when the sleeve is replaced, all presser feet need to be disassembled and installed in turn, which is time-consuming and labor-intensive. In addition, during the disassembly process, the presser feet are easily lost, which is inconvenient. Summary of the invention

[0005] The existing amorphous alloy transformer has a bushing which is fixed by multiple pressing feet, which makes it difficult to quickly disassemble and install it. To solve this problem, the following invention is proposed:

[0006] An amorphous alloy transformer includes a transformer body and a top cover, wherein the top cover is fixedly mounted on the transformer body, a sleeve and a plurality of fixing mechanisms arranged in an arc shape with the sleeve as the center are provided on the top cover, a tube pin that fits the top cover is provided on the sleeve, the fixing mechanism is also fixedly connected to the top cover, a fixing block is elastically connected inside the fixing mechanism, a fixing head and a driving arm are provided on the fixing block, the fixing head is pressed against the top of the tube pin to fix the sleeve on the top cover, a driving inclined surface is provided on the driving arm, a disassembly sleeve that contacts the driving inclined surface is provided above the driving arm, and the disassembly sleeve is movably connected to the top cover. After the disassembly sleeve moves downward, it contacts the driving inclined surface to drive the driving arm to move toward the side away from the sleeve, and then the fixing head will be separated from the top of the tube pin and will no longer press against it, thereby releasing the fixing of the sleeve.

[0007] Furthermore, the fixing mechanism also includes a mounting seat and a mounting cover, the mounting seat is fixedly mounted on the top cover, the top cover is provided with a guide hole for the driving arm to move through, and a mounting groove is also provided in the mounting seat, and the fixing block is elastically connected to the mounting groove through a spring.

[0008] Furthermore, a fixing column extending vertically from the top cover and penetrating the mounting seat and the mounting cover is provided on the fixing block, and a guide groove for movably inserting the fixing column is provided on the fixing block. When the fixing block moves, the guide groove moves horizontally relative to the fixing column, and a first fixing piece is threadedly connected to the top of the fixing column to fix the mounting cover and the mounting seat on the top cover.

[0009] Furthermore, a first positioning column is vertically extended from the top cover, and a positioning hole matching the first positioning column is provided at the bottom of the mounting seat to prevent the mounting seat from rotating relative to the fixing column.

[0010] Furthermore, a guiding slope is also provided at the end of the fixing head, and when the sleeve moves downward from the upper part of the fixing head, the tube pin contacts the guiding slope to push the fixing head to move.

[0011] Furthermore, a plurality of second positioning posts are vertically extended on the top cover, and a plurality of positioning sleeves are provided on the disassembly sleeve. The second positioning posts are inserted into the positioning sleeves to flexibly connect the top cover and the disassembly sleeve. After the disassembly sleeve moves vertically, the positioning sleeve moves vertically on the second positioning posts.

[0012] Furthermore, at least one second positioning column is provided with an external thread, and a second fixing member located above the positioning sleeve and a third fixing member located below the positioning sleeve are threadedly connected to the second positioning column with the external thread. By adjusting the positions of the second fixing member and the third fixing member, the disassembly sleeve can be fixed at any angle, thereby changing the contact area between the fixing head and the pin.

[0013] Furthermore, a spring column is provided in the installation slot, a spring slot is provided on the fixing block, one end of the spring is sleeved on the spring column and abuts against the installation slot, and the other end is inserted into the spring slot to elastically connect the installation slot and the fixing block.

[0014] Furthermore, a matching plate extending downward and attached to the outer side of the mounting seat is provided on the mounting cover, and the matching plate prevents the mounting cover from deviating relative to the mounting seat.

[0015] The present invention proposes an amorphous alloy transformer, on the top cover of which a bushing and a fixing mechanism are provided, wherein a fixing block is elastically connected inside the fixing mechanism and is pressed against the pin of the bushing to fix the bushing, and a disassembly sleeve is provided above the fixing block, which can drive the fixing block to move and release the pressure on the pin after moving downward. The beneficial effect of the present invention is that the operator only needs to move the disassembly sleeve to quickly fix or release the bushing, thereby making the installation and disassembly process of the bushing more time-saving and labor-saving, and reducing the possibility of parts loss.
