The embedded resistance thermometer is also used to measure the stator temperature. The temperature measuring element is embedded in the stator core. First, place the temperature measuring element in a suitable groove on a fan-shaped insulating connecting piece, and then glue it with epoxy resin. When stacking the iron core, fold the fan-shaped piece into a certain part of the iron core like a silicon steel piece. In selected parts, the resistive elements are led out with shielded wires.
For water-cooled generators, because the stator core operates at a higher temperature and the edge core may cause local overheating, more temperature measuring elements are generally buried, and some are even buried evenly along the circumference. Many points. Along the axis, there are many measuring points at the ends, and most of the measuring points in the middle are buried in the hot air section; along the radial phase, they can be placed at the tooth root or the yoke. The temperature of the tooth root core is measured when placed at the tooth root. It is placed on the yoke to measure the temperature of the iron core at the yoke.
