<P>PROBLEM TO BE SOLVED: To reduce wiring working man-hours for a compressor in a driving device configured of a driving circuit for driving the compressor, a zero-phase current transformer provided in a power supply input part, and an interruption circuit for detecting a state of the zero-phase current transformer and operating itself. <P>SOLUTION: The driving device 1 for driving the compressor 2 includes: the driving circuit 8; the zero-phase current transformer 5 provided in the power supply input part; and the interruption circuit 7 for detecting the state of the zero-phase current transformer 5 and operating itself. Accordingly, as the wiring 9 for power supply to the compressor 2 is only employed, the man-hour for installing an overload protection device is not needed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
