In addition, the terms "first", "second" and "third" are only used for descriptive purposes and are not to be construed as indicating or implying relative importance.

[0025] like Figure 1-4 It is a structural schematic diagram of an open-type transformer in a preferred embodiment of the utility model. In this embodiment, an open-type transformer includes a transformer body 1, which is composed of a first shell 2 and a second shell 3. The first shell 2 and the second shell 3 are both designed with a semicircular structure. A first connecting device 4 is fixedly connected to the left and right sides of the outer wall of the first shell 2, and a second connecting device 5 is fixedly connected to the left and right sides of the outer wall of the second shell 3. The first connecting device 4 passes through the second connecting device 5 and is threadedly connected with a butterfly nut 7, thereby realizing a locking effect on the first shell 2 and the second shell 3 after assembly. A plurality of protective devices 6 are fixedly connected to the inner walls of the first shell 2 and the second shell 3. The protection of the cable is achieved by setting the protective device 6, thereby solving the problems raised in the background technology.

[0026] In this embodiment, the protection device 6 includes a connecting seat 61 and an anti-collision pad 62. A sliding groove 63 is provided on the connecting seat 61. The anti-collision pad 62 is slidably connected in the sliding groove 63, thereby realizing the replacement function of the anti-collision pad and having the function of long-term use.
