Abstract
PURPOSE: To prevent the machine parts from damage in a stage of overcurrent by a method wherein the secondary current generated based on motor line current is compared with a preset value and according to its result the operation of a compressor is controlled.
CONSTITUTION: When the line current comes to rise during the operation of the compressor motor 107 the secondary output current of current transformers 100, 101 rises to above the normal value. Said value is put in a comparison circuit 102 to be compared with the current value preset by a circuit 103. And when said value is bigger than the set value the comparison circuit 102 sends a compressor motor stop signal to an output circuit 104 to release a contact 105. In this way the compressor motor 107 is made to stop. At a time of starting, a stop cancell circuit 106 operates to cancel the stop signal due to overcurrent detection and to continue the operation.
