In the conventional thermal conduction gas purity measuring device configured as shown in Fig. 2, the gas pressure inside the rotating electric machine 1 is used to send out the analysis gas, so as the gas pressure decreases and approaches atmospheric pressure, The required flow rate could no longer flow through the gas purity transmitter 5, and measurement could not be performed. Another drawback was that the gas after measurement had to be constantly discarded, albeit in a small amount.

いため計測が不可能となる。 In addition, in the gas purity measuring device configured as shown in Fig. 3, there is no need to release the analysis gas to the atmosphere, and even if the gas pressure inside the rotating electrical machine 1 reaches atmospheric pressure, it rotates integrally with the rotating electrical machine 1 shaft. As long as the gas in the rotating electric machine 1 is circulated by the fan, a blower differential pressure is generated, and it is possible to secure the flow rate necessary for the gas purity transmitter 5. However, when the rotating electric machine 1 itself is stopped, even if the gas pressure is high, there is no high pressure zone or low pressure zone and gas does not flow, making measurement impossible.
