摘要： A partial discharge detection apparatus of an electrical rotating machine includes a metal frame connected to a stator frame of the electrical rotating machine, a power line connected to one of a stator winding corresponding to one phase of three phases in the metal frame and a neutral point lead line connected to a neutral point of three-phase stator windings and arranged in the metal frame to propagate a partial discharge signal generated by degradation of the stator winding, a sensor including a rod antenna which is installed around the power line or neutral point lead line in the metal frame to electrostatically and magnetically induce the partial discharge signal propagated to the power line or neutral point lead line, and a detector which receives, via a signal lead line, a signal generated in the sensor and detects partial discharge by signal processing.

摘要： Each coil fixing member is placed between a stator coil and at least one end surface of a stator core in an electric rotary machine in order to suppress a displacement between the stator core and the stator coil. The coil fixing member consists of a spacer and a bolt. The bolt and a corresponding screw hole formed on an end surface of the stator core are used to fix the stator core in the electric rotary machine. The spacer consists of a main body part and a bolt fixing part. The bolt fixing part has a bolt hole. The main body part has a tapered shape. The main body part is placed between the end surface of the stator core and connection parts of windings of the stator coil, and fixed to the stator core by the bolt through the bolt hole of the bolt fixing part.
