[0042] For details, please refer to Figure 1 One side end of the capacitor compensation cabinet 1 is movably hinged with a door panel 2 through a hinge shaft, and the material of the door panel 2 is stainless steel.

[0043] In this embodiment: the door panel 2 allows maintenance personnel to easily open the door panel 2 to inspect, maintain or replace internal components, thereby improving the efficiency of daily operation and maintenance. Stainless steel is used as the main material. Stainless steel not only has excellent corrosion resistance, but can also withstand erosion under various harsh environmental conditions and maintain long-term beauty and functionality.

[0044] For details, please refer to Figure 4 The lower end of the capacitor compensation cabinet 1 is fixedly connected with an exhaust box 3, and the inner walls on both sides of the capacitor compensation cabinet 1 are fixedly connected with a grid 11 at the close ends.
