Description of the Related Art In order to protect the temperature of a rotating electric machine winding, a thermocouple or a resistance temperature detector may be attached to monitor the temperature. Generally, a resistance thermometer is used in many cases, and a vertical cross-sectional view of a rotating electric machine showing the mounting method of the resistance thermometer used for the conventional temperature monitoring of the stator winding and the main part of the stator. 4 and 5 are cross-sectional views of FIG. Regarding the mounting position of the resistance temperature detector, it is necessary to store it in the part where the temperature becomes the highest, so it is generally inserted between the upper coil and the lower coil of the stator winding 4 as shown in FIG. Target. On the other hand, since the number of RTDs 6 to be mounted is usually only one or two for each phase, spacers 7 are inserted in many other stator slots 3 to leave a space in the stator slots 3. I was adjusting.

た。In the conventional method of attaching the resistance temperature detector described above, the resistance temperature detector 6 is placed in the stator slot 3.
Since it is necessary to provide a space for storing the
Was provided with a space for storing. For this reason, it is necessary to upsize the rotating electric machine because copper loss increases as compared with the rotating electric machine in which the resistance temperature detector 6 is not attached. Further, the resistance temperature detector 6 is usually installed in a small number of one or two for each phase, and many stator slots 3 in which the resistance temperature detector 6 is not installed.
It was necessary to insert a spacer 7 in the to adjust the gap of the stator slot 3, and it was necessary to perform a very wasteful work.

少となり回転電機の大形化が防げる。According to the method of mounting the resistance temperature detector used for monitoring the temperature of the winding according to the present invention, the space of the winding slot required for mounting the resistance temperature detector is smaller than that of the mounting portion of the resistance temperature detector. Since there is only a winding slot, the increase in copper loss is smaller than in the past, and it is possible to prevent the size of the rotating electrical machine from increasing.

Therefore, the measured temperature is higher than other parts, and the highest temperature of the winding can be measured.

の導体断面積と同一となる。According to the method of mounting the resistance temperature detector 6 of the present invention, the number of windings of the stator winding 4 of the stator slot 3 is reduced only in the stator slot 3 of the portion where the resistance temperature detector 6 is mounted. The number of windings of the stator winding 4 is set to the extent that the body 6 can be inserted. Therefore, many stator slots 3 to which the resistance temperature detector 9 is not attached have the same conductor cross-sectional area of the stator winding when the resistance temperature detector 6 is not used.

Further, it is not necessary to insert the spacer 7 of the stator slot 3 to which the resistance temperature detector 6 is not attached. Regarding the problems of resistance, reactance, and magnetic balance, there is no problem because the resistance temperature detectors 6 are mounted in the same number each and the mechanical angles are 120 °.
