POWER DISTRIBUTION SWITCHBOARD COMPRISING MULTI FEEDER RELAY HAVING AUTOMATIC SETTING FUNCTION, AND AUTOMATIC SETTING METHOD FOR OPERATING PROPERTIES OF MULTI FEEDER PROTECTION RELAY

摘要

The present invention relates to a power distribution switchboard comprising a multi feeder relay having an automatic setting function (high-tension panel/low-tension panel/MCC panel/panel board) to which a multi feeder relay setting technology is applied, wherein the multi feeder relay setting technology does not require setting each feeder one by one via additional correction calculation by allowing a corresponding feeder relay to be automatically selected and set by only setting a main relay of a multi feeder relay. The power distribution switchboard comprising a multi feeder relay having an automatic setting function according to an embodiment of the present invention comprises: a main over-current relay (OCR) module and a main over-current grounding relay (OCGR) module for controlling operations of a circuit breaker installed in an input end; a feeder over-current relay (OCR) module and a feeder over-current grounding relay (OCGR) module for controlling operations of a circuit breaker installed in each feeder; and a control unit for setting operating properties of the main OCR module, the main OCGR module, the feeder OCR module, and the feeder OCGR module. The control unit automatically calculate and set operating properties of each feeder OCR module and each feeder OCGR module.;COPYRIGHT KIPO 2016
