[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core. Its main functions include voltage conversion, current conversion, impedance conversion, isolation, etc. With the continuous development of society and the continuous progress in the field of transformer technology, the working mode and structural design of transformers have become more and more mature. When using transformers, specific protective devices are required to store them. However, the existing protective devices cannot be easily transported during use, and multiple stacked transformers cannot be fixed. In addition, the insulation performance is poor. The existing protective devices are cumbersome to install on the transformer. In many cases, the transformer needs to be lifted to install, which is laborious and inconvenient.

[0004] To achieve the above-mentioned purpose, the main technical solution of the present invention is to provide a transformer with an insulating protective shell, including a transformer body with a support foot at the bottom, a protective shell is inserted on the left and right sides of the transformer body, the protective shell is provided with a groove, a spring and a tubular handle are provided in the groove, the two ends of the spring are respectively connected to the bottom of the groove and the handle, the outer diameter of the handle in the groove of one protective shell is slightly smaller than the inner diameter of the handle in the groove of the other protective shell, the two protective shells are provided with a latch assembly for closing the groove, and the top and bottom ends of the protective shell are hinged with a fixing hook.

[0005] In some embodiments, the longitudinal section of the protective shell is an E-shaped with two slots, and the top and bottom protrusions of the transformer can just be inserted into the two slots of the protective shell.

[0006] In some embodiments, the latch assembly includes a pin seat fixed on the protective shell and a pin rod movably disposed in the pin seat.

[0007] In some embodiments, both the top and bottom ends of the protective shell are provided with accommodating grooves for accommodating fixing hooks.

[0008] In some embodiments, the fixing hook includes a spoke plate hinged in the receiving groove and an arc-shaped hook connected to the spoke plate. The fixing hook can be rotated out to hook the support leg of the transformer, and can be rotated back to be hidden in the receiving groove.

[0009] In some embodiments, the protective shell uses a wooden board or a plastic board as a frame, and a rubber layer is attached to the outside of the frame. BRIEF DESCRIPTION OF THE DRAWINGS
