INTELLIGENT RECOVERY SYSTEM, CAPABLE OF WATCHING AND CONTROLLING THE STATE OF AN EARTH LEAKAGE BREAKER

摘要

PURPOSE: An intelligent recovery system is provided to rapidly cut off or restore an earth leakage breaker by confirming the trip cause of the earth leakage breaker in a remote site.;CONSTITUTION: An automatic recovery device(100) operates the lever of an earth leakage breaker(10) by the trip of the earth leakage breaker. The automatic recovery device comprises a rotary arm, a voltage detecting part, an overload detection part, and a controller. A rotary arm pressurizes the front or rear side of the lever of the earth leakage breaker. The voltage detecting part detects the output of the load side voltage of the earth leakage breaker. The overload detection part detects an excess current of the load side of the earth leakage breaker. The controller outputs a control signal for cutting off or recovering the breaker according to a trip cause. A data collecting unit(200) collects trip information of the earth leakage breaker from the automatic recovery device.;COPYRIGHT KIPO 2010
