  "textContent": "The invention discloses a power distribution system, including a system power supply, a main control unit, a power line and a number of subsidiary control units. The main control unit comprises a main controller and a main power circuit protection device connected to the main controller. The input end of the main power circuit protection device is connected to the power output end of the system power supply, and the output end of the main power circuit protection device is connected to an end of the power line. Each subsidiary control unit comprises a subsidiary controller and a subsidiary power circuit protection device connected to the subsidiary controller. The input end of the subsidiary power circuit protection device is connected in parallel to the power line, and the output end of the subsidiary power circuit protection device is connected to the electrical device. The present invention constructs a two-level power supply protection architecture from the system power supply to the electrical device in a structural form consisting of a main control unit, a subsidiary control unit and a power line. The main control unit constitutes the protection of the power line, and the subsidiary control unit constitutes the protection of itself and connected electrical devices.",
