محافظ اضافه بار موتور دو فلزی کوچک

The necessity of motor overload protection:

When the motor is running, it is generally allowed to overload for a short time (the output power exceeding the rated value is called overload). هر چند, if the overload time is too long and the temperature rise of the motor exceeds the allowable value, it will cause insulation aging, shorten the service life, and even burn the windings in severe cases. از این رو, in order to prevent damage to the motor due to long-term overload operation, the overload time must be limited. This protection is overload protection.

معمولا, 5AP/2MP/6AP به عنوان وسیله حفاظت از اضافه بار موتور استفاده می شود. هنگام استفاده, عنصر حرارتی را وصل کنید (سه فاز یا دو فاز) محافظ اضافه بار به صورت سری به مدار اصلی موتور. کنتاکت اصلی رله حرارتی را به صورت سری به مدار سیم پیچ کنتاکتور وصل کنید.

When the motor overload operation, the current is increased, the heating element temperature rises, the bimetal gently curved, and thus exceeds the predetermined value, and finally open the normally closed contacts, so that the motor coil is deenergized. So as to cut off the power of the motor and avoid the motor from being burnt due to long-term overload operation.
