Similarly, the second opening 1142 and the second access opening 143 are also configured to enable personnel to access the neutral point equipment 141 in the neutral point equipment cabinet 140 through the second opening 1142 and the second access opening 143 . Therefore, the second opening 1142 and the second inspection opening 143 have a certain area, and the overlapping area between the second opening 1142 and the second inspection opening 143 is also large (the overlapping area is greater than 80% of the second inspection opening 143) , even completely overlapping, so that people can enter. The electrical system 100 also includes a second access baffle 132 removably mounted on the first side panel 114 and shielding the second opening 1142 .
