The utility model discloses an anti-thunder protective device for accessories of a variable-pitch control system. The device is characterized by being composed of a collector plate, a carbon fiber brush and a gasket pressing plate, wherein a seat board of the carbon fiber brush is fixedly overlapped with the middle part of a front edge of the collector plate by a screw; the gasket pressing plate is fixedly overlapped with the middle part of an upper plate surface of the collector plate by a bolt. According to the anti-thunder protective device for the accessories of the variable-pitch control system, the quantity of thunder strike electric charge can be effectively received and released through current collection claws, and meanwhile electric charge generated in a running process of the variable-pitch control system can be released by a spark discharger, so an insulator, wires and a fan circuit of the variable-pitch control system can be prevented from thunder strike more effectively, and the anti-thunder protective device is simple in structure, convenient to maintain and easy to install.
