Abstract
A cooling medium temperature monitoring system for a rotary electric machine for cooling stator coils by as cooling medium flowing in a plurality of cooling medium passages provided in the stator coils, has a plurality of temperature detectors for measuring the temperatures of the cooling medium in the outlets of the plurality of cooling medium passages; and a circuit for setting the temperature warning value at a value which is responsive to the output of a generator, and a calculator circuit for comparing the detected outputs of the temperature detectors with the set value of the warning value setting circuit to generate an alarm signal when the output of any one of the detectors exceed the set warning value.
Claims5
A cooling medium temperature monitoring system for a rotary electric machine for cooling stator coils by means of a cooling medium flowing in a plurality of cooling medium passages provided in the stator coils, comprising:
- a plurality of temperature detecting means for measuring the temperatures of the cooling medium in the outlets of the plurality of cooling medium passages and for providing outputs corresponding thereto;
- a means for setting temperature warning values as a function of the output of a generator, and
- a means for respectively comparing said outputs of said plurality temperature detecting means with said set warning values of said warning value setting means and for generating an alarm signal when said output of any of said plurality of detecting means exceeds a corresponding set warning value.
