One end of the bottom plate 1 is provided with an upwardly bent bending part 1.1, and the included angle between the bending part 1.1 and the bottom plate 1 of the embodiment is 135°. This design optimizes the pressure relief channel of the cable chamber, has an advantage in pressure relief compared with the large bending plate cabinet body with a right angle, and the distance from the oblique angle type bending part to the current transformer is increased, the distance between the live copper bar and the ground is increased, and the safety performance is increased. The end of the bending part 1.1 is rotatably connected with a connecting plate 4 through a plurality of hinges 3, a plurality of threaded holes 4.1 are formed in the vertical end of the connecting plate 4, a fastening screw 5 is screwed in each threaded hole 4.1, and the bottom of the back plate 2 is fixed in the threaded hole 4.1 of the connecting plate 4 through a plurality of fastening screws 5. In the embodiment, the back plate is installed on the connecting plate, the connecting plate can be rotated relative to the bottom plate through the hinge, the folding of the back plate and the bottom plate is realized, and the folding structure can reduce the boxing space of the product and reduce the transportation and storage cost.

[0039] Preferably, a limiting plate 1.1.1 extending to the back of the connecting plate 4 is fixedly installed on the back of the bending part 1.1, and is used for limiting the rotation angle of the connecting plate 4. Specifically, when the back plate is unfolded, the limiting plate limits the back plate to be in a vertical state with the bottom plate after unfolding, and has a self-positioning effect during installation, thereby improving the installation efficiency.
