1. the turbodynamo water-cooled winding internal water circulation system method of inspection is characterized in that it comprises the steps:

  • one, on the rising pipe outside surface of each stator winding temperature-measuring element is set respectively;

    Two, simultaneously to feeding the normal-temperature water of uniform temp in each stator winding;

    Three, reach the steady state (SS) of temperature after, in each stator winding, feed the high-temperature water of uniform temp again;

    Meanwhile write down the process of temperature variation on the rising pipe outside surface;

    Four, calculate the speed that each rising pipe hull-skin temperature changes, less than the rising pipe of average ramp rate more than 10%, assert that it is the stator winding that there is stopping state in inside for rate temperature change.
