<P>PROBLEM TO BE SOLVED: To provide an air conditioner which can prevent the abnormal heating of the other reactor caused by current concentration by detecting the opening by wire breaking of either of reactors connected in parallel by one CT. <P>SOLUTION: The currents of a first rector 1 and a second reactor 2 are inputted in a direction of negating each other into an AC detecting means 4, whereby in case that either reactor is opened, the AC detecting means 4 can detect the open state, at the same set value as a conventional overcurrent set value. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
