Infrared-temperature-measurement-based Method for Maintenance of Running High-voltage Equipment
Aiming at timely and effective fault perception of running electrical equipment,this study introduced infrared temperature measurement technology to maintenance of running high-voltage equipment and performed a case verification on an actual apparatus.According to the maintenance requirements,surface temperature of the electrical equipment was detected using infrared temperature measurement. Temperature losses of running medium and high voltage electrical e-quipment were measured and calculated to compensate the measured temperature.According to relevant standards and technological specifications,thermal failure of running equipment was clearly defined,and the abnormal temperature rise warning value was determined,so as to achieve calculation of abnormal temperature rise and fault maintenance.The ex-ample application results showed that the proposed method can achieve accurate fault troubleshooting and maintenance of running high-voltage equipment on the basis of improving perception accuracy of infrared spectrum temperatures,and con-sequently ensure stability and reliability of electrical equipment operation in power system.
