Ultrasonic transducer for detection and location of the acoustic emission signals, generated by partial discharges

摘要

The ultrasonic converter (1) for the detection and location of acoustic emissions signals generated by incomplete discharges shall be characterised by the fact that the transformer housing, fitted with the outlet (15) and the flange (9) of the inspection window, is made of high mechanical strength dielectric material, Inside it are at least four piezoelectric elements, each equipped with a pair of electrodes, a pair of electrical wires, a fitting element and a damping element.
