Abstract

PURPOSE:To facilitate the protective cooperation of a nonbreak interruption power unit while enabling the continuous supply of power to sound load by a method wherein the currents of branch load circuits are detected when they reache to a fixed value is detected and the branch load circuit are then interrupted. CONSTITUTION:A plurality of branch load are connected to a power source device formed by a plurality of power source devices having a drooping characteristic. Breakers formed by circuits among terminals 6, 7 are connected in series with each branch load. Load currents are detected by means of detecting coils 17, currents which the detected currents are rectified and potential-divided are compared with the voltage of reference voltage power sources 18, external voltage tripping coils 21 are energized by output from the comparators 17 when the load currents exceed the reference value, and breakers 20 are broken. The inverter power source device, whose output is lowered by the drooping characteristic, recovers output again after the branch load circuits are interrupted.
