HIGH VOLTAGE CIRCUIT BREAKER FOR INTERRUPTING FAULT CURRENT BY DELAYED ZERO CROSSING

摘要

the present invention relates to a circuit breaker for highvoltage capable of cutting fault current.pseudo period t and zero crossing delay fromafter a certain period of time, from zero to the maximum tzmax afterthe time to onset of failure, this time tzmax.as determined by simulation or testing, includinga plurality of chambers in series with power (1)how to open a moment later.the second failure to and ways of blowing of the arcdesigned to operate between time t1 and a time tcprior to the second tzmax. there are ways toreduction in flow adapted to the blowingthe swelling is extended up to a time t2 between- and tzmax tzmax + t.
