A New Vibration Analysis Approach for Detecting Mechanical Anomalies on Power Circuit Breakers

Abstract: On-line monitoring and the diagnosis of the high-voltage circuit breaker (HVCB) have been discussed and investigated significantly in the past few decades. The vibration analysis is a noninvasive and advanced diagnostic technique suitable for the detection of mechanical conditions during the HVCB operation, which plays an important role in improving the operating reliability of HVCB and reduces maintenance costs. However, due to the very complicated mechanical system and extremely short operation time of HVCB,… Show more

“…To give an illustration, deformation of shaft, close coil, insulation pull rod, and damper of CB have been investigated based on the vibration signals in [51]. Similarly, in [53], the malfunction in damper and insulation push/pull rod have been identified using vibration. While the earlier is dealt with absorbing the residual energy and reducing the impact of mechanical collision during HVCB operating, the latter transmits the required energy from operating mechanism to the dynamic contact to perform closing and opening operation.…”

“…The main disadvantage of this method is the dependency of its accuracy on the number of sensors and the post processing techniques as discussed in IV-A. The reason lies in the fact that this signal is quite short in the time domain whereas the inherently highly nonlinear and non-stationary vibration signals are extremely wide in the frequency domain [53].…”

“…This paves the requirement for customized condition monitoring approaches for sea. One of the most powerful tools for predictive or condition-based maintenance is 'Vibration Analysis' [7]. Vibration analysis is a reliable approach for identifying faults at an early stage and preventing unexpected Machine Downtime.…”

“…To address this issue, many methods have been proposed. For example, an energy entropy of Hilbert marginal spectrum based on vibrational mode decomposition is presented to analyze it [11]; another research introduced a non-linear feature mapping in the wavelet package time-frequency energy rate feature space based on random forest binary coding to extend the feature width [12]. In addition, two layers of independent one-class support vector machines are adopted to distinguish normal or fault conditions with known or unknown fault types respectively.…”
