Estimating the term…
The present disclosure relates to a simultaneous detection method and system for dissolved gas and partial discharge in insulating oil, and belongs to the field of electrical devices. The method includes the steps: freely diffusing the dissolved gas in the insulating oil to an F-P optical fiber interference cavity through an oil-gas separation membrane; coupling pump light and probe light into the F-P optical fiber interference cavity through a frequency division multiplexer; making, by an optoacoustic effect of the dissolved gas stimulated by the pump light and an ultrasonic wave generated by the partial discharge, the oil-gas separation membrane vibrate; detecting, by the probe light, vibration of the oil-gas separation membrane, which changes a cavity length, wherein when the probe light is reflected by the oil-gas separation membrane, an interference signal is generated due to the change of the cavity length.
A simultaneous detection method for dissolved gas and partial discharge in insulating oil, comprising the following steps:
