The invention discloses a lightning protection device of pitch control system accessories. The lightning protection device is characterized by being formed by a power collector plate, a carbon fiber brush and a gasket pressing plate; a base plate of the carbon fiber brush plate is fixed in the middle of the front edge of the power collector plate through a screw in a stacked mode; the gasket pressing plate is fixed in the middle of the upper plate surface of the power collector plate through a bolt in a stacked mode. According to the lightning protection device of the pitch control system accessories, the lightning electric charge quantity can be effectively absorbed and released through a power collector claw, meanwhile the electric charge produced in the operation process of a pitch control system is released through a spark discharger, and accordingly the lightning stroke of an insulator, a lead and a fan circuit which are arranged in the pitch control system can be effectively prevented, the structure is simple, the maintenance is convenient, and the installation is easy.
