PRESSURE RELIEF ENCAPSULATED ELECTRO-MAGNETIC PARTIAL DISCHARGE SENSOR

摘要

PURPOSE: A rupture disk integrated electromagnetic-wave partial-discharge sensor is provided to improve the sensitivity and reduce noises by integrating an electromagnetic wave partial discharge sensor to electric appliances. CONSTITUTION: A rupture disk(11) releases abnormal pressure generated in electric appliances. A sensing part(12) is integrated into the rupture disk. The sensing part detects electromagnetic-wave partial-signal and extracts a power signal. A plurality of opening parts is arranged in the sensing part. In the sensing part, pressure generated in the electric appliances is transmitted to the rupture disk through the opening parts.
