Abstract: A fan mounting assembly includes a mounting bracket and a fan support. The mounting bracket is arranged on a side of the power device, and the fan support connected to the fan and detachably secured to the mounting bracket. The mounting bracket has a supporting surface for supporting the fan support. The mounting bracket has a first limiter on a side of the mounting bracket towards the power device, the fan support has a second limiter, and the second limiter is matched with the first limiter so that the second limiter is limited from moving relative to the first limiter in a first direction, the first direction is perpendicular to the supporting surface. The fan support is lockable to the mounting bracket on a side of the mounting bracket away from the power device.

Abstract: A cabinet and a substation for photovoltaic power generation are provided. The cabinet includes a cabinet body and branch switches arranged in the cabinet body; each branch switch includes a load switch and fuses; at least two input terminals and at least two output terminals are respectively provided for the load switch and are sequentially distributed in the depth direction of the cabinet body; the fuses, the input terminals, and the output terminals are in one-to-one correspondence; fuse output ends of the fuses are electrically connected to the input terminals; at least two fuses in the branch switch are sequentially distributed in the depth direction of the cabinet body; and the depth direction of the cabinet body is perpendicular to the width direction and the height direction of the cabinet body. According to the structural layout, the depth space of the cabinet body is fully utilized.
