Technical Field

Background
Along with the continuous improvement of the power demand of China, particularly in the application of an ultrahigh voltage direct current power transmission and transformation system, the safety and reliability of the power system are ensured. The high voltage equipment is often damaged due to the factors such as arc, corona, partial discharge and the like, and even the damage of paralysis of a power system can be caused.
Just like corona discharge occurring on high voltage transmission lines, it causes not only loss of electric power but also interference with broadcast television signals. The corona activity of the transmission line, particularly the remote transmission line, is detected in the air, so that the safety of the line and the power transmission and transformation equipment is facilitated. However, the corona discharge can seriously affect the personal safety, so that timely and accurate detection of the position and strength of the corona discharge has important significance for ensuring reliable operation of a power system, reducing equipment damage and ensuring personal safety. Meanwhile, the successful early detection and early warning can save tens of millions of expenses for an electric company, so that the detection of corona generated by overhead transmission lines and power transformation equipment has great commercial value.

Abnormal corona caused by insulation defects outside a circuit is often accompanied by electromagnetic radiation and optical radiation, and the optical detection has good anti-interference performance and high sensitivity, and has a relatively high application prospect in online monitoring of abnormal corona of the circuit. In general, the optical detection method judges the defect state by receiving the optical pulse signal sent by the discharge fault source through the optical sensor, and can avoid the influence of sunlight on the measurement result by adopting an ultraviolet filtering mode, but the mode reduces the sensitivity of optical detection and sacrifices the discharge spectrum components of ultraviolet band, so that the detection capability of the defect is limited in actual use, and the sensitivity is not high.
