[0035] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0036] The invention includes a differential pressure vector sensor, a high-frequency carrier communication module and an analysis device. The differential pressure vector sensor is set in the insulating oil of electrical equipment to collect discharge information; the high-frequency carrier communication module is used to send the information transmitted by the differential pressure vector sensor to the analysis device; the analysis device is set in the control room for The information collected by the differential pressure vector sensor is analyzed to obtain the specific location of the partial discharge source.
[0037] The differential pressure vector sensor includes a spherical structure in which there are six double-stacked bending piezoelectric ceramic sensors 3, six data acquisition modules 4, and a connecting rod for fixing the double-stacked ...
