[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a transformer comprehensive tester, including a transformer comprehensive test instrument 1, an external circuit interface 3, and a manual operation switch 4. A component storage groove 2 is provided on the front side frame of the transformer comprehensive test instrument 1, and the external circuit interface 3 and the manual operation switch 4 are installed inside the component storage groove 2, and the external circuit interface 3 and the manual operation switch 4 are fixedly connected to the transformer comprehensive test instrument 1. A first positioning iron sheet 5 is installed on the inner side of the front end of the transformer comprehensive test instrument 1, and a second positioning iron sheet 6 is installed on the left surface of the transformer comprehensive test instrument 1. A sealing protection frame 7 is installed on the front side of the transformer comprehensive test instrument 1, and a stable straight bar 8 and a combined frame 9 are installed on the outer surface of the frame of the sealing protection frame 7, and the combined frame 9 is located inside the component storage groove 2. A magnetic attraction stone 10 is installed on the frame of the combined frame 9, and the magnetic attraction stone 10 is connected to the first positioning iron sheet 5.

[0021] The first positioning iron sheet 5 and the second positioning iron sheet 6 are fixedly connected to the transformer comprehensive test instrument 1 by inlaying, and the connection method between the first positioning iron sheet 5 and the second positioning iron sheet 6 and the magnetic attraction stone 10 is magnetic connection, so that the first positioning iron sheet 5 and the second positioning iron sheet 6 can be fixed on the transformer comprehensive test instrument 1 and then stabilized by magnetic connection with the magnetic attraction stone 10, improving the installation positioning stability.

[0022] The connection method between the sealing protection frame 7 and the stable straight bar 8 is heat fusion fixing, and the stable straight bars 8 are symmetrically distributed on the sealing protection frame 7, so that the stable straight bars 8 can be fixed on the sealing protection frame 7. When the sealing protection frame 7 is disassembled later, it can be pulled through the stable straight bars 8, and the operation is convenient and fast.

[0023] The combined frame 9 and the sealing protection frame 7 are integrally structured, and the length and width of the combined frame 9 are greater than those of the sealing protection frame 7, and the connection method between the combined frame 9 and the component storage groove 2 is snap connection, so that the sealing protection frame 7 can be snap-positioned with the component storage groove 2 through the combined frame 9, which is convenient, stable and suitable for performing protection work.

[0024] The connection mode of the magnet block 10 and the combined frame 9 is inlaid and fixed. The magnet blocks 10 are symmetrically distributed on the combined frame 9, and the outer surface of the magnet block 10 is flush with the outer surface of the combined frame 9. According to the magnet blocks 10 on the combined frame 9, it is beneficial to magnetically stabilize the combined frame 9 through the magnet blocks 10 subsequently, which is convenient for positioning.

[0025] Working principle: According to Figures 1-4 , when it is necessary to conduct a comprehensive test on the transformer through the external circuit interface 3 and the manual operation switch 4 on the transformer comprehensive test instrument 1, the stable straight bar 8 on the sealed protection frame 7 can be manually toggled. The stable straight bar 8 pulls the sealed protection frame 7, and the sealed protection frame 7 drives the combined frame 9 to slide and separate from the component storage groove 2. At the same time, the magnet block 10 on the combined frame 9 is magnetically separated from the first positioning iron sheet 5, which is convenient for opening operation. Then, after the sealed protection frame 7 and the combined frame 9 are installed on the left side of the transformer comprehensive test instrument 1, the magnet block 10 on the combined frame 9 is attached to the second positioning iron sheet 6 on the transformer comprehensive test instrument 1, so as to perform magnetic positioning and avoid the phenomenon of mutual separation and loss. Then, the operation can be carried out through the external circuit interface 3 and the manual operation switch 4 on the transformer comprehensive test instrument 1. The transformer comprehensive test instrument 1, the external circuit interface 3 and the manual operation switch 4 are known and existing technologies in the market, and will not be described in detail here. The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
