The invention belongs to a helicopter rotor anti-icing and de-icing technology, and particularly relates to a main paddle distributor with a fault isolation function and a fault isolation method. The main paddle distributor is composed of a switch element, a control module of the switch element, a signal processing module, a switch element voltage checking module, a current checking module and a power supply module. The switch element and the control module thereof are used for controlling on-off of an alternating current power supply of the main blade heating element; the signal processing module is connected with the switch element voltage checking module, the heating current checking module and the power supply module, and is used for controlling the on-off of the switch element, collecting fault information, isolating faults, and judging and reporting the faults; the switch element voltage checking module is used for detecting the voltage state of the switch element; and the current checking module is used for detecting the C-phase heating current state of the main paddle blade. According to the invention, the problem that the main paddle heating element is difficult to isolate from the main paddle distributor fault is solved, the testability and fault response capability of the main paddle distributor are improved, and the accuracy and safety of the architecture are improved.
