GIS equipment vibration signal detector

Abstract

The invention discloses a GIS equipment vibration signal detector. The GIS equipment vibration signal detector comprises a sensor, a signal processing unit, a signal acquisition unit and an upper computer; the sensor is arranged on a detection point of GIS equipment and is used for detecting local vibration signals generated in the GIS equipment; the signal processing unit is used for filtering, amplifying and detecting the detected signals; the signal acquisition unit is used for converting amplified electric signals into digital quantity; and the upper computer detects the characteristic quantity of the signals and carrying out waveform statistics analysis so as to realize fault detection. With the GIS equipment vibration signal detector adopted, the mechanical and discharge faults of the GIS equipment can be accurately detected; the launch of the state maintenance work of the GIS substation electrical equipment can be effectively guided; the latent defects of the equipment can be detected timely; huge economic losses caused by the maintenance and disassembly of the GIS can be prevented; and the safety, reliability and stability of the GIS equipment can be improved.

Description

Technical field: [0001] The invention relates to a device for detecting GIS mechanical and discharge faults, in particular to a GIS device vibration signal detector. Background technique: [0002] Vibration is any movement that is repeatedly reproduced after a certain time interval. Vibration theory refers to the theory that studies the relationship between the vibration law of an object and the force acting on the object. The principle of mechanical vibration is the reciprocating motion of an object near the equilibrium position. Vibration is very common in engineering technology. Mechanical vibration is a ubiquitous phenomenon in engineering. Parts and complete machines of mechanical equipment vibrate to varying degrees. The vibration of mechanical equipment often affects its working accuracy, aggravates the wear of the machine, and accelerates fatigue damage; and with the increase of wear and fatigue damage, the vibration of mechanical equipment will become more severe,...
