Description

Background Art

[0002] As an important power transmission and transformation equipment, the number and scope of use of gas-insulated-switchgear (GIS) are growing rapidly. However, when partial discharge occurs, a large number of GIS ultra-high frequency sensors lose sensitivity due to serious aging and unreasonable layout, resulting in missed alarms. There is still a lack of effective solutions.

[0003] For the calibration of the UHF built-in sensors pre-installed inside the GIS, due to the attenuation of the UHF electromagnetic waves when propagating in the GIS cavity and the complex electromagnetic environment inside the equipment, they cannot be disassembled and placed in the GTEM electromagnetic compatibility chamber for calibration. At present, the calibration method of equivalent pulse field strength injection is usually adopted at home and abroad. This method simulates the UHF electromagnetic waves excited by local discharge by injecting voltage pulses into the adjacent built-in sensors of the built-in sensors to be calibrated. The electromagnetic waves propagate in the GIS and eventually reach the sensors to be calibrated and output voltage signals. If the sensor to be calibrated can detect the pulse signal injected by the adjacent sensor, it is considered that the performance of the sensor meets the minimum requirements; otherwise, it is considered that the sensitivity of the sensor decreases or a fault occurs. However, the current equivalent field strength injection method has high requirements for the amplitude of the injection amount. When the injection amount is too large, even if the sensitivity of the built-in sensor to be calibrated decreases, there may be obvious voltage output due to the strong electromagnetic waves caused by the excessive injection voltage; and when the injection amplitude is too low, even if the performance of the built-in sensor to be calibrated is good, there may be no obvious output due to insufficient electromagnetic waves excited by the adjacent sensors. Therefore, it is urgent to provide a technical solution to solve the above problems. Summary of the invention
