Synchronous machine j p, 187. As shown in Figure 14.56 (Denki University Publishing Bureau), the space between the hydrogen gas release valve and the atmosphere release pipe is always filled with air, and when the hydrogen gas release valve opens, the atmosphere and hydrogen gas mix inside the pipe. was configured to do so.

った。However, when hydrogen gas mixes with oxygen in the atmosphere, it becomes explosive gas, and when sparks are generated due to static electricity, it can explode and burn. Therefore, when hydrogen gas is actually released, hydrogen explosion or combustion may occur. It was dangerous.

管内の大気を不活性ガスで置換することにより達成され
る。The above object is achieved by installing an inert gas supply device between the hydrogen gas release valve and the atmosphere release pipe, and replacing the atmosphere in the pipe with the inert gas prior to hydrogen gas release.

Automatically seals inert gas into the pipe from the inert gas supply device. As a result, the atmosphere (including oxygen) that was present in the tube is pushed out into the atmosphere, and the tube is filled only with inert gas.
この状態で、水素ガス放出弁を開くと、管内のどこにも
、水素ガスの燃焼・爆発の可能性はなくなり、安全な水
素ガス放出装置が得られる。When the hydrogen gas release valve is opened in this state, there is no possibility of combustion or explosion of hydrogen gas anywhere in the pipe, and a safe hydrogen gas release device is obtained.
以下、本発明の一実施例を第1図により説明する。 An embodiment of the present invention will be described below with reference to FIG.

電機1内の水素ガスを大気中へ放出する。Hydrogen gas is supplied to the generator 1 from a hydrogen gas supply device 2 . When releasing the hydrogen gas in the generator 1 into the atmosphere, open the hydrogen gas atmosphere release valve 3 and open the atmosphere release pipe 4.
The conventional method was to release hydrogen gas into the atmosphere through a In the present invention, since the inert gas supply device 5 is provided between the hydrogen gas release valve 3 and the atmosphere release pipe 4, first, the inert gas is supplied from the hydrogen gas release valve 3 by the inert gas supply device 5. The hydrogen gas is sealed in a pipe leading to the atmosphere, and after the atmosphere is no longer present in the pipe, the hydrogen gas release valve 3 is opened and the hydrogen gas in the generator 1 is released into the atmosphere.

計22でも良い。The method of knowing when to open the hydrogen gas release valve 3 may be any method as long as it can ensure that there is no atmosphere in the pipe, for example, a method using a timer 11 as shown in Fig. 2 may be used. The flow meter 21 or the gas concentration meter 22 shown in FIG. 1 may be used.
また、不活性ガスの種類は、水素と爆発的に反応しない
ガスなら何でも良く、例えば、窒素ガス。Further, the type of inert gas may be any gas that does not react explosively with hydrogen, such as nitrogen gas.
炭酸ガス、アルゴンガスなどが挙げられる。Examples include carbon dioxide gas and argon gas.
