In order to solve the above problems, a double-bus power distribution system is proposed, as shown in patent No. CN212114888U, but the double-bus system is relatively disordered in actual use and is easy to cause short circuit due to cross use due to misoperation; and the reliability is poor, for example, if one mini bus is in power failure for maintenance, and the equipment connected to the other mini bus needs maintenance, the normal use of the subsequent equipment cannot be ensured. Accordingly, there is a need for a new distributed power distribution system.
