Abstract

When the circuit breaker is operated

the opening and closing coil current can reflect the operating state of the circuit breaker operating mechanism or the secondary circuit.Analyzing the characteristics of the opening and closing coil current

which is of great significance for the fault diagnosis of the circuit breaker.In this paper

a method for extracting the current characteristic value of the opening and closing coil based on modified ensemble empirical mode decomposition（MEEMD） is proposed.The method uses MEEMD to decompose the current signal of the opening and closing coil current

obtains the empirical modal component（IMF）

then finds the instantaneous frequency of the component

and uses the coordinates corresponding to the peak in the frequency spectrum to characterize the eigenvalue of the original signal.The experimental results show that the method can correctly and effectively extract the characteristics of the opening and closing coil current.
