[0050] The embodiment of the present application discloses a box-type substation that facilitates maintenance. The principle of operation is as follows: when the baffle 6 and the fixing plate 5 are locked and high-voltage equipment or low-voltage equipment needs to be inspected, the handle 8 is first driven to move along the axis of the slot 73. The handle 8 drives the block 75 via the driving rod 77 to move, causing the block 75 to disengage from the first slot 58. Simultaneously, the handle 8 drives the locking block 91 to move synchronously. When the fixing slot 811 is aligned with the limiting slot 78, the locking spring 92 resets, driving the locking block 91 to insert into the limiting slot 78, thereby limiting the handle 8 and, in other words, the block 75. The mounting plate 7 is then driven to rotate, causing the mounting plate 7 to disengage from the locking slot 57 and insert the block 75 into the second slot 62. Finally, the baffle 6 is driven to rotate, opening the operating hole 52, facilitating maintenance of the high-voltage equipment in the high-voltage chamber 13 or the low-voltage equipment in the low-voltage chamber 11 within the transformer chamber 12. Otherwise, the baffle 6 blocks the operating hole 52.
