Saat ini, under normal operation of the generator, the temperature rise in the middle section of the stator core is much higher than that at the end. Namun, during the phase leading operation of the generator, komponen struktur logam di ujung inti stator akan menghasilkan suhu lokal yang tinggi, dan kenaikan suhunya bahkan mungkin lebih tinggi daripada kenaikan suhu bagian tengah inti stator. Dalam perancangan pembangkit listrik tenaga air skala kecil dan menengah, resistor pengukur suhu hanya ditanam di bagian bawah slot inti stator dan di antara dua lapisan kumparan stator untuk memantau suhu operasi bagian tengah inti stator (dan kumparan). Namun, ketika generator beroperasi secara fasa, ada kurangnya pemantauan yang diperlukan untuk pemanasan akhir inti stator. Huaguang Tianrui telah mengembangkan lampu neon secara mandiri pengukuran suhu serat optik perangkat yang dapat memonitor suhu perangkat jari tekanan stator generator pembangkit listrik tenaga air.
The stator pressure finger temperature measuring device and fluorescent fiber optic stator end temperature monitoring system of the hydroelectric generator can monitor the heating at the end of the stator core in real time through sensor suhu serat optik neon, effectively ensuring the safe operation of the unit
With the increasing demand for electricity in modern society and the improvement of technological level, large generator sets at present usually have characteristics such as high capacity and large parameters. The requirements for various systems of large generators are becoming increasingly high, especially for the operation and maintenance of the generator cooling water system. Namun, dalam kenyataan, the cooling water system of generators often fails to meet relevant standards, resulting in some generators being overheated and damaged. Accidents in the generator cooling water system can have many impacts on the normal operation of the generator, and even lead to safety accidents. In view of this, power generation institutions must pay attention to the phenomenon of abnormal temperature rise of large generator stator bars, master corresponding preventive technologies and measures to manage large generator stator bars, and prevent safety accidents from occurring.
To detect the abnormal temperature rise of large generator stator bars, FJINNO’s fluorescent fiber temperature monitoring technology needs to be used. Its function is to monitor the temperature of large generator stator bars 24/7. If the temperature is found to be abnormally rising or has exceeded the standard temperature, an early warning will be issued as soon as possible. Saat ini, relevant personnel can confirm the cause of the temperature anomaly and take action.
