れた絶縁劣化検知装置を端子箱等に一体的に設けてなる
こと・。 を特徴とする絶縁劣化検知装置付電動機。[Claim for Utility Model Registration] In an operating electric motor connected to an AC power source, the output of the secondary coil of a zero-phase current transformer generated due to leakage current of the motor is transmitted to a relay via a semiconductor amplifier. In addition, when the output of the zero-phase current transformer reaches a predetermined level, an insulation deterioration detection device configured to operate the relay and activate a response device such as an indicator light is integrated into the terminal box, etc. It will be set up. An electric motor equipped with an insulation deterioration detection device.
