The built-in resistance thermometer is also used to measure the stator temperature. The temperature measuring element is integrated into the stator core. Firstly, put the temperature measuring element into a suitable groove on a fan-shaped insulating connecting piece, and then stick 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 part. In some parts, the resistive elements are taken out with shielded wires.
For water-cooled generators, since the stator core operates at a higher temperature and the peripheral core may cause local overheating, more temperature measuring elements are generally buried, and some are even buried evenly along the circumference. points. Along the axis, there are numerous measuring points at the ends.ities, 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 arch. The iron core of the tooth root is measured when placed at the root of the tooth. It is placed on the arch to measure the temperature of the iron core at the arch.
