RELAY COORDINATION CIRCUIT FOR LIMITING OVERCURRENT AND METHOD THEREOF

摘要

Protection coordination circuit, prevent fuse from cutting first in this way and carry out dynamical system that protection coordination is well on by suitably control circuit overcurrent fault electric current whether gas leakage accident or input distributed power and for its method. Current limit circuit limitation overcurrent flows into transmission line and includes; Switch is connected to transmission line series connection, in item from power device; The transmission line being connected in series between a kind of relcoser is from switch and load; A kind of current limit circuit is connected to the parallel connection of switch. The current limit circuit includes that semiconductor devices and fuse are connected to semiconductor circuit series connection. ;The 2014 of copyright KIPO submissions
