Abstract

A break control method for electric breaker converts phase current flown through breaker to voltage type via one proper resistor, then sampling the value with constant sampling frequency fs=nfAC(in which fs is sampling frequency, n is sampling times of every power cycle, fAC is power frequency). When sampling reaches one power cycle, then calculating current average value according the sampled value, squaring the current average value and multiplying it with power cycle to get energy value of one power cycle. According to breaking condition set by external, values corresponding to a variety of breaking reference ones pre-stored in memory are read out, and compared with the energy value, if breaking condition is satisfied, then immediately controls the breaker to break.
