[0011] Furthermore, the interiors of the protective plate 1 and the protective plate 2 are filled with sound-absorbing cotton.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] Through the cooperation between the T-block and the T-slot, when the staff silences the transformer, they can directly align the T-block on the protective plate 1 with the slot and install it inside, so that the protective plate 1 can be fixed to the transformer body, which is convenient for the staff to quickly install and disassemble, avoids the need to use tools for installation, and indirectly reduces the labor cost of the staff.
