摘要： PURPOSE:To enable a windmill to be stopped in a short time with a large brake power when the revolution speed of the windmill power generator increases close to the breakdown limit in case of a strong wind, by installing a mechanical brake, and to reduce the grade of the breakage of the apparatus even if the power generator is started with brake application. CONSTITUTION:When a windmill power generator 28 is brought closely into the hait state by application of an electromagnetic brake 24, the electromagnetic brake 24 is released, and a mechanical brake 29 is applied. Said brake 29 is operated in the friction system with the spring force, and an electromagnetic solenoid is energized in case of both setting ON and OFF of the brake 29, but the brake 29 does not require supply of the energy in case of locking revolution. As the revolution power generated by a Dalius-type windmill in stop state is remarkably small, the windmill power generator can be kept in the hait state for a long time by the friction system 29 with a spring force having a relatively small brake power even in a strong wind range. Further, even if the power generator is started with the erroneous application of brake, water-out of brake shoe can be reduced.
