[0035] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific examples.

[0036] The present application provides a transformer product with a side line outlet, and a structure diagram of the transformer product with a side line outlet is as shown in Figure 1 and Figure 2 The transformer product with a side line outlet includes a shell 10, an inner core (not shown in the figure) arranged in the shell 10, an external wire group 30, and a shielding cover 40. The inner core includes an iron core and a winding arranged on the iron core. One end of the external wire group 30 is connected to the winding, and the other end is a free end. The free end penetrates through the side wall of the shell 10 to be led out to the outside of the shell 10. The shielding cover 40 is arranged on the shell 10 and covers the free end to shield and protect the free end.

[0037] According to the prior art, it can be known that a sleeve is usually arranged on the free end. The sleeve is protrudingly arranged on the side of the shell 10. This arrangement effectively reduces the overall height of the transformer and facilitates the stacking and transportation of the transformer. Importantly, the free end of the present embodiment is located on the side of the shell 10. Although the overall height of the transformer is effectively reduced, the side is more likely to have problems such as collision or scratching. Therefore, the shielding cover 40 shields and protects the free end or the sleeve on the free end.

[0038] In addition, the overall frame of the shell 10 is a hexahedron, which includes two large sides and two small sides. Preferably, the free end is arranged on the large side.

[0039] Optionally, the shielding cover 40 comprises a housing 41 and a door body 42; the housing 41 is arranged on the shell 10 and surrounds the circumferential side of the free end, and the door body 42 covers the side of the housing 41 away from the shell 10 to shield the free end.

[0040] Illustratively, the housing 41 is a tetrahedral frame, so that the housing 41 is sleeved around the free end, and the door body 42 is rotatably arranged on the housing 41, and the door body 42 is closed to shield the free end. In addition, the outer side of the door body 42 is provided with a door handle for grasping and controlling the opening and closing of the door body 42.

[0041] In addition, in the vertical direction, the top of the housing 41 is inclined downward and away from the shell 10, so as to avoid the influence of dust accumulation on the top on the free end when the door body 42 is opened. In addition, the bottom of the housing 41 is provided with an opening, which is used for other external lines to pass through and connect with the free end.

[0042] Optionally, the external line group 30 comprises a high-voltage input line 31, a high-voltage output line 32, a low-voltage input line 33 and a low-voltage output line 34; one end of each of the high-voltage input line 31, the high-voltage output line 32, the low-voltage input line 33 and the low-voltage output line 34 is connected to the winding, and the other end is the respective free end.

[0043] Among them, according to the prior art, it is known that the winding generally comprises a primary coil and a secondary coil. In this embodiment, the primary coil is taken as the high-voltage end, and the secondary coil is taken as the low-voltage end, so that the high-voltage input line 31 and the high-voltage output line 32 are connected to the primary coil respectively, and the low-voltage input line 33 and the low-voltage output line 34 are connected to the secondary coil respectively. At this time, the four lines correspond to four free ends. Preferably, in the vertical direction, the free ends of the high-voltage input line 31 and the high-voltage output line 32 are arranged in alignment, and the free ends of the low-voltage input line 33 and the low-voltage output line 34 are the same. In addition, it should be noted that a safety distance is reserved between each free end according to the power design requirement, which will not be expanded here.

[0044] Optionally, all the free ends are arranged on the same side wall of the shell 10.

[0045] Illustratively, all the free ends are arranged on the same large side, so that all the free ends can be shielded by one shielding cover 40. The number of shielding covers 40 is reduced, and the overall structure is simplified.

[0046] Optionally, it further comprises a wiring assembly 50, and the wiring assembly 50 comprises a wiring slot 51, one end of which is connected to the side of the shell 10, and the other end extends to the edge of the side and is at least aligned with the edge of the side.
