[0036] Specifically, the cabinet body 1 includes a first fixed plate, a second fixed plate 12, a third fixed plate 13, a fourth fixed plate 14, a fifth fixed plate 15, and a sixth fixed plate 16. The first fixed plate, the second fixed plate 12, the third fixed plate 13, the fourth fixed plate 14, the fifth fixed plate 15, and the sixth fixed plate 16 are combined with each other to form a cuboid-shaped cabinet body 1, and are fixedly connected by bolts to facilitate disassembly. The first chamber 7 is formed by the gap between the second fixed plate 12 and the transformer 21, and the second chamber 8 is formed by the gap between the fourth fixed plate 14 and the transformer 21.
