vibrometer of suddenpressure relay in power transformer and controlling method thereof

摘要

PURPOSE: A device, for measuring the vibration of pressure relay for converter, and a controlling method thereof are provided to prevent the malfunction of a pressure relay due to high frequency vibration. CONSTITUTION: A device, for measuring the vibration of pressure relay for converter, comprises an enclosure vibration measurement sensor(310), a relay vibration measurement sensor, a signal analyzer, and a display part. A plurality of enclosure vibration measurement sensors is installed at the enclosure and respectively measures the vibrations about the enclosure. A plurality of relay vibration measurement sensors measures all kinds of the vibrations which are generated from the pressure relay. The signal analyzer receives vibration data and changes into data of frequency domain. The display part displays data of the frequency domain which is transformed by the signal analyzer.
