PURPOSE:To reduce current before a current limiting circuit breaker is actuated by making a current limiting request to each end circuit when the current over the setting does flow. CONSTITUTION:If the current flowing to an incoming line exceeds the set value, then the primary request to limit the current will be made from an output section 8 of a current limiting control circuit 2 and a load in less importance will be interrupted corresponding to the primary demand by supply control circuits 14, 15 and 16. Unless the current flowing to the incoming line gets below the set value for all that, then the secondary request to limit the current will be made from the output section of a current limiting control circuit 2 and a load in less importance next to supply control circuits 14, 15 and 16 will be interrupted. Not withstanding unless the current flowing to the incoming line gets below the set value, all the power supply will then the interrupted by the actuation of a circuit breaker 3. |
