At the same time, pipe joints are designed on both sides of the partition, and the two cabinets are connected through a connecting pipe 4, which maximizes the space saving of the connecting pipe.

[0027] Specifically, the connecting pipe 4 is connected between the main oil conservator 2 and the switch oil conservator 1, and the connecting pipe 4 includes a butt pipe 401, a connecting pipe 402, and a connecting pipe 403.
