Summary:PROBLEM TO BE SOLVED: To provide a switchgear for power distribution that can enhance reliability by expanding protection range to enable short-circuit protection of the entire loads side including circuit breakers. SOLUTION: Circuit breakers 11 arranged in series, current transformers 12, and a zero-phase current transformer 10 are configured in unit, which are mounted on a carrier 14 and accommodated in an incoming switchboard 1. A switchgear unit 9 for power distribution is contactably and separably comprised of a conductor at power supply side 20 and conductors on load side 33, 34. The zero-phase current transformer 10 is arranged at power supply side of the circuit breakers 11 side. COPYRIGHT: (C)2008,JPO&INPIT
