Description

Technical Field

[0001] The invention belongs to the technical field of detection equipment, and in particular to a multi-point casing vibration online monitoring system and method based on self-energy extraction. Background Art

[0002] As an important power equipment, the operating conditions of the pressure bushing are relatively harsh, and both external insulation and internal insulation problems must be considered. Among various high-voltage bushings, porcelain bushings are the most widely used due to their many advantages. Porcelain bushings adopt high-temperature firing technology, with good structural stability, excellent insulation performance, high voltage resistance, and can adapt to various harsh environments such as high temperature, high pressure, low temperature and humidity, and have a long service life. However, there are two relatively important factors that restrict the application of porcelain bushings. One is that porcelain bushings are highly brittle, have low fracture toughness, low damage tolerance, and are sensitive to cracks; the other is that there is a lack of means to detect the state of mechanical strength (cracks) during the operation of porcelain bushings, and there are insufficient means to prevent explosion accidents.

[0003] In view of the hidden dangers of existing bushing failures, it is difficult to monitor the mechanical strength status of the bushing due to its appearance design and installation position, and there is a lack of effective monitoring methods. The existing bushing monitoring is based on the vibration method to realize bushing status monitoring, and mostly adopts offline monitoring methods, that is, vibration testing is performed when the bushing is tested at the factory or power outages for maintenance. The factory test cannot eliminate the safety hazards generated during the operation of the bushing, and the frequency of power outage maintenance testing is too low to timely discover and eliminate hidden faults. A small number of online monitoring methods mainly monitor the bushing close to the ground potential area. When detecting other potential areas of the bushing, especially the high potential areas, it is necessary to equip the corresponding high-voltage isolation transformer for external power supply and related electromagnetic shielding components. When monitoring multiple potential areas of the bushing at the same time, each point needs to be equipped with an isolation transformer of the corresponding potential, which requires huge costs and is difficult to achieve.

The storage unit 12 is provided with an associated storage unit, and the associated storage unit stores the call information corresponding to the exact time after the sorting unit 13 classifies and sorts based on the time. The control unit is used to input a call signal into the storage unit 12, and call the call information in the associated storage unit in the storage unit 12 and the corresponding associated time-stamped vibration information, the associated time-stamped comparison result information and the associated time-stamped warning information. The display unit 11 is used to display the associated time-stamped vibration information, the associated time-stamped comparison result information and the associated time-stamped warning information, and display the associated time-stamped vibration information, the associated time-stamped comparison result information and the associated time-stamped warning information of the casing to the user, that is, display the vibration waveform and the corresponding warning information.
