巻線保護装置。In a protection device for protecting a motor winding of the compressor, which is installed in a heat pump refrigeration cycle in which a compressor, an outdoor heat exchanger, a pressure reduction mechanism, etc. are connected in sequence, the outdoor heat exchanger is connected to the outdoor heat exchanger from the discharge side of the compressor. A hot gas bypass pipe is provided to bypass the discharged gas to the pipe line connecting the and the pressure reducing mechanism.
The hot gas bypass pipe is provided with an on-off valve to open and close it, and the temperature of the winding is detected by the temperature of the compressor case or the discharged gas discharged from the compressor case, and the detected temperature reaches the set temperature. A motor winding protection device for a compressor of a refrigeration cycle, characterized in that the control circuit is provided with a control circuit that opens the on-off valve and allows the discharged gas to pass through the hot gas bypass pipe when the temperature reaches the hot gas bypass pipe.
