Analysis on the Infrared Imaging Diagnosis Technology for the Insulation State, Fault Types, and Components of Coupling Capacitor

Abstract:

Along with the continuous development of Chinese economy, the power consumption continues to rise in China, and many high-voltage electric transmission lines are constantly put in construction. Among them, coupling capacitor is a major coupling device in the carrier communication of the power frequency high-voltage lines, and also a device that has been widely used for measuring and extracting electric energy, and controlling high-frequency protection in the electric power system. However, there are many problems in the application of coupling capacitor to high-voltage electric transmission lines. In the following, some common problems in the application of infrared imaging diagnosis technology to the coupling capacitor in high-voltage electric transmission lines are tested, so that the corresponding problems are found timely and accurately and also the right processing is made.
