Floresan fiber optik sıcaklık ölçümü, stator sargı sıcaklığı ölçümü, Büyük jeneratörler için stator çekirdek sıcaklığı ölçümü

Due to the fact that the main heating parts of the stator of a hydroelectric generator are located in various parts of the inner iron core of the stator, stator voltajı çok yüksek olduğunda, demir kaybı artar; Or as the load current increases, the copper loss in the stator winding increases; Veya güç faktörü azalırsa, rotorun önceki akımı artar; Veya dengesiz üç fazlı yük akımı gibi faktörler stator sıcaklığının artmasına neden olabilir.. When the temperature rises too quickly or reaches the warning value, derhal ilgili önlemler alınmazsa, it will reduce the insulation performance of the insulation layer wrapped in the stator core or cause insulation breakdown, which is prone to problems and lead to malignant power outages. Öyleyse, Hidroelektrik jeneratörlerin stator sıcaklığının gerçek zamanlı izlenmesi çok önemlidir. Bir enerji santralinin ana ekipmanı olarak, Jeneratörün sağlık durumu güvenlik açısından büyük önem taşıyor, güvenilir, ve ünitenin verimli çalışması. Jeneratör gövdesindeki arıza türlerinde, Aşırı yüklemeden kaynaklanan aşırı ısınma hataları, soğutma sistemi tıkanıklığı, su kesintisi, vesaire. stator sargı sıcaklığında hızlı bir artışa neden olabilir, damage insulation parts and conductors, cause faults in the generator and its connected electrical equipment, and have an impact on the power grid. Ek olarak, generator failures require a long maintenance cycle and extremely high maintenance costs. If not detected and dealt with early, it will bring great hidden dangers.

The stator sıcaklık sensörü is responsible for measuring the actual temperature of the stator winding of the motor. Due to the large current flowing through the stator of the motor during operation, the heating of the stator is very severe, and the temperature rises rapidly. The sensor is arranged inside the stator winding to measure the actual temperature of the stator winding in real time. Fakat, once the stator overheats, the entire motor control system will be very dangerous, and the motor may be burned out and cause serious accidents. Öyleyse, stator temperature sensors are very important in motor control systems. Once the stator temperature sensor malfunctions, the motor control system must take corresponding emergency measures to protect the entire motor system. With the continuous improvement of national requirements for power safety, the operating temperature of generator sets, as an important indicator of safe operation of generator sets, has become particularly important. Aralarında, the stator operating temperature of the generator set is the most important non electrical quantity monitoring parameter of the generator, which is directly related to the safe and stable operation of the generator set and the working life of the generator set.

In the generator stator temperature monitoring system, by simultaneously monitoring the temperature of the stator coil, stator iron core, and stator air outlet of the generator, it can also facilitate relevant personnel to determine the fault location of the generator, thereby improving the management efficiency of the staff. The generator stator and rotor fiber optik sıcaklık ölçüm sistemi includes a power station backend control system, unit status monitoring screen, stator system signal regulator, stator fiber optic probe, rotor system signal regulator, rotor fiber optic probe, rotor slip ring, industrial computer, relay device, communication conversion module, photoelectric conversion module, wireless transmitter, wireless receiver, wireless transmitter power supply, wireless receiver power supply, VGA transmitter, VGA receiver. The fiber optic temperature measurement system for generator stator and rotor can resist electromagnetic interference, be safe, withstand high voltage, kimyasal korozyon, yüksek sıcaklık, yaşlanma, and has small size, yüksek hassasiyet, hızlı tepki hızı, düşük enerji tüketimi, ve yüksek doğruluk. Öyleyse, they are widely used in strong electric and magnetic field environments. After being applied to generator sets, it can accurately measure the real-time temperature of the stator and rotor of the generator set online, which helps to understand and evaluate the technical performance of the generator and ensure the safety of large and medium-sized generators.
