１１の連結作用によって回転を始める空気機械（例えば
プロワ−）１２より構成されている。As shown in Figure 2, the overspeed prevention device of this wind power motor is connected to the rotating shaft 7' of the generator Y, and is a non-powered, non-controlled type that transmits rotational force by its own centrifugal force when the rotation exceeds a certain level. It consists of a coupling device (also called a clutch) 11, and an air machine (for example, a blower) 12 that starts rotating by the coupling action of the coupling device 11.
以上のように構成された風力原動機の過回転防止装置に
ついて、以下その動作について説明する。The operation of the wind power motor overspeed prevention device configured as above will be described below.
先ず通常の風速では、風車翼１が風を受けて動力軸３が
回転し、増速機５．軸継手６を介して発電機７を駆動す

で可変ピッチ装置２の故障やまた突風等により風車翼２
の回転が異常に高くなったときは直ちに、制動機４を制
御器８により作動させて、風車翼２の回転を止めるよう
にしている。First, at normal wind speed, the wind turbine blades 1 catch the wind, the power shaft 3 rotates, and the speed increaser 5. A generator 7 is driven via a shaft coupling 6. Next, when the wind speed increases, the variable pitch device 2 is controlled by the controller 8.
, and suppresses the increase in rotation of the wind turbine blade 1. Here, due to a failure of the variable pitch device 2 or a gust of wind, etc., the wind turbine blades 2
When the rotation of the wind turbine blade 2 becomes abnormally high, the brake 4 is immediately activated by the controller 8 to stop the rotation of the wind turbine blade 2.
しかしながら強風下において可変ピッチ装置２の故障の

選定することにより風車翼による回転動力は、プロワ−
１２の仕事にすべて消費され、風車の過回転は防止され

たのは、作動流体として空気が取扱いが簡単で故障し々
いこと、また、空気機械（例えばプロワ−や圧縮機）の
動力は回転数のほぼ３乗に比例しているため、風車の出
力が回転数のほぼ３乗に比例することと相殺される形に
なることによる。However, in a strong wind, if the variable pitch device 2 fails, the brake 4 fails, or the controller 8 or power supply 1o fails, the wind turbine blade 2 may rotate at an abnormally high speed. In such a case, when a certain rotation is reached, the coupling device 11 is activated, and this coupling device drives the air machine (for example, a blower) 12 to select the capacity of the blower above a certain level. The rotational power generated by the wind turbine blades is then transferred to the propeller.
All 12 jobs will be consumed and the windmill will be prevented from over-speeding. The reason why an air machine was used to absorb the rotational power is because air is easy to handle as a working fluid and tends to break down easily, and the power of air machines (e.g. blowers and compressors) is approximately 3 times the rotational speed. This is because the output of the wind turbine is approximately proportional to the third power of the rotation speed, which cancels out the output of the wind turbine.
