AN ACOUSTIC EMISSION SENSOR TO DETECT PARTIAL DISCHARGE IN TRANSFORMER

摘要

PURPOSE: A non-directional sound radiating sensor for detecting a partial discharge of a transformer is provided to manufacture devices for detecting radiating signals and analyzing dissolved gases in oil to be integrated, thereby obtaining the reliability of a transformer safety inspection technology. CONSTITUTION: A non-directional sound radiating sensor for detecting a partial discharge of a transformer comprises: an oil path(13) installed in an outer wall of the transformer; a sound radiating sensor(15) installed inside the oil path; and a sensor supporting unit(16) fixing the sound radiating sensor.
