A Model-Based Fault Detection Framework for Vacuum Circuit Breaker by Trip Coil Analysis
Vacuum circuit breaker becomes more and more complicated, integrated, high-speed and intellectualized. To insure vacuum circuit breaker in its good conditions, the function of fault diagnosis gets more important than before in the process of repairing. This paper is addressed a modelbased fault detection framework for vacuum circuit breaker by trip coil analysis. At first, the electromagnetic m...
متن کاملThe EMvibe: An Electromagnetically Actuated Vibraphone
The EMvibe is an augmented vibraphone that allows for continuous control over the amplitude and spectrum of individual notes. The system uses electromagnetic actuators to induce vibrations in the vibraphone’s aluminum tone bars. The tone bars and the electromagnetic actuators are coupled via neodymium magnets affixed to each bar. The acoustic properties of the vibraphone allowed us to develop a...
متن کاملControl of an Electromagnetically Actuated Resonance Punch
In the area of metal forming the production of micro-components in huge quantities by cutting plays a central role. These components are often manufactured on modified mechanical high speed presses with stroke rates of up to 4,000 strokes per minute (spm) and punching forces of up to 2,000 kN. In terms of maximum cutting force and overall size of the punching machine, this may represent a signi...
متن کاملReliability modeling and data analysis of vacuum circuit breaker subject to random shocks
The electrical substation components are often subject to degradation due to over-voltage or over-current, caused by a short circuit or a lightning. A particular interest is given to the circuit breaker, regarding the importance of its function and its dangerous failure. This component degrades gradually due to the use, and it is also subject to the shock process resulted from the stress of iso...
متن کاملAutomated Analysis of Circuit Breaker Operation
In this paper a new approach to the analysis of test results for circuit breakers is discussed. It is implemented through new software called Automated Circuit Breaker Monitoring system ACBM. The circuit breaker performance is evaluated based on the analysis of Digital Fault Recorder (DFR) recordings taken from circuit breaker control circuitry. This paper describes the testing procedure and us...
