[0025] The following is a combination of the appended examples of the present invention Figure 1-6 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] As shown in the figure, a transformer that is easy to maintain includes a transformer body 1, a base 2 and a shell 3. A front door hole 31 is provided on the front side of the shell 3, and a front door panel 4 is provided on the front door hole 31. The transformer body 1 is fixedly provided on the base 2, and the shell 3 can be slidably provided on the base 2 forward and backward. The shell 3 slides backward to make the transformer body 1 completely exposed from the shell 3.

[0027] Specifically, the shell 3 is slidably arranged on the base 2: a sliding support plate 21 with a length greater than the width of the base 2 is provided on each of the left and right sides of the base 2, and a first sliding groove 22 is provided on the inner side of the sliding support plate 21. The lower ends of the left and right sides of the shell 3 are each rotatably provided with a plurality of first rollers 32 that match the first sliding groove 22, and the first rollers 32 are retained in the first sliding groove 22.

[0028] Specifically, the front door panel 4 is arranged on the front door opening 31: a second sliding groove 33 is provided on the left and right side walls of the front door opening 31, and the lower ends of the left and right sides of the front door panel 4 are rotatably connected to a second roller 41 that matches the second sliding groove 33, and the second roller 41 remains in the second sliding groove 33.

[0029] In the above embodiment, under normal conditions, the transformer is located on the base 2 in the space formed by the shell 3 and the front door panel 4, which protects the transformer. When a small-scale maintenance is required on the transformer body 1, the front door panel 4 is pulled upward to make the second roller 41 roll upward in the second sliding groove 33. When the second roller 41 rolls to the uppermost end of the second sliding groove 33, the front door panel 4 leaves the position limited by the port of the front door opening 31 and can rotate on the shell 3 through the rotation of the second roller 41 in the second sliding groove 33, so that the front door panel 4 can be Figure 6 As shown, the front door 4 is flipped and placed on the upper end of the shell 3. At this time, the front side of the transformer can be easily inspected, and because the front door panel 4 is flipped, it will not be located on the left or right side of the front door hole 31 after the door of the traditional transformer cover is opened, thereby avoiding obstruction to the inspection operation, thereby facilitating the inspection of the transformer. When a larger range of inspection is required on the transformer body 1, that is, when inspection operations are required on the front, back, left and right sides of the transformer body 1, after opening the front door panel 4, the shell 3 is pushed, and the first roller 32 rolls in the first slide groove to make the shell 3 slide backward on the base 2, so that the transformer body 1 passes through the front door hole 31 and is completely exposed in the shell 3. Figure 6 As shown, at this time, since the front, back, left and right sides of the transformer body 1 are not blocked, the maintenance operation on the transformer body 1 is convenient.

[0030] Preferably, the sliding support plate 21 is composed of a fixed plate 211 and a swinging plate 212. The fixed plate 211 is fixedly connected to the base 2, and the swinging plate 212 is rotatably connected to the fixed plate 211. The fixed plate 211 and the swinging plate 212 are respectively provided with a fixed slide groove 221 and a swinging slide groove 222. When the swinging plate 212 swings to connect with the end of the fixed plate 211, the swinging slide groove 222 is aligned with the fixed slide groove 221 to form a first sliding groove 22. In normal state, the swinging plate 212 is swung to make it swing on the fixed plate 211 and fold relative to the fixed plate 211, thereby reducing the space occupied by the sliding support plate 21 and facilitating the transportation and installation of the transformer. When the transformer needs to be converted to a maintenance state, the swinging plate 212 is swung to make its end aligned with the fixed plate 211.

[0031] Preferably, the fixed plate 211 and the swing plate 212 are respectively fixedly connected with a first connecting rod 213 and a second connecting rod 214, and the first connecting rod 213 is provided with a tension spring 215 whose other end is provided on the second connecting rod 214. Under the action of the tension spring 215, the swing plate 212 can be more stably maintained in a position folded relative to the fixed plate 211 or aligned with the end of the fixed plate 211.

[0032] Preferably, a rear door hole 34 is provided on the rear side of the shell 3, and a rear door panel 5 is provided on the rear door hole 34. Specifically, a third sliding groove 35 is provided on the left and right side walls of the rear door hole 34, and the lower ends of the left and right sides of the rear door panel 5 are rotatably connected to a third roller 51 that matches the third sliding groove 35. The third roller 51 remains in the third sliding groove 35. The rear door panel 5 can be opened and flipped over and placed on the shell 3 in the same way as opening the front door panel 4, which is convenient for operations when only the rear side of the transformer body 1 needs to be inspected.

[0033] Preferably, a handle 6 is fixedly connected to the outer side of each of the front door panel 4 and the rear door panel 5 , and the handle 6 is used to facilitate opening the front door panel 4 or the rear door panel 5 .

[0034] Preferably, the base 2 is provided with a locking plate 23 located below the front door panel 4, and a locking groove 231 matching the front door panel 4 is provided on the upper end surface of the locking plate 23. A locking bolt 24 is passed through the locking plate 23. When the front door panel 4 slides downward so that the lower end of the front door panel 4 is inserted into the locking groove 231, the locking bolt 24 is screwed onto the front door panel 4. When the transformer is in normal state, the locking bolt 24 cooperates with the locking groove 231 to lock the front door panel 4. By locking the front door panel 4, the sliding of the shell 3 on the base 2 is limited, so that the transformer can be kept more stably in normal state.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
