Overload protection is actuallyThree-phase asynchronous motor manufacturersOverload protection device installed to prevent the main power line from overheating and damaging the protector due to overload. In machinery, overload protection can prevent equipment damage caused by overload when the shaft exceeds the load it can bear.
Three-phase asynchronous motorOverload means that the operating current exceeds the rated value, causing the winding to overheat; There are many reasons for overload, such as sudden increase in load, power supply and voltage reduction, or bearing wear, which will cause overload.
In factAsynchronous motorOverload is similar to overcurrent, but there is also a difference. The main difference is that the effects of the action are different; Overcurrent is caused by electromagnetic effects to cause the protection device to act, which is aimed at the instantaneous size of the current; Overload protection refers to the thermal effect of the current, when a current causes the action of the protective device caused by the accumulation of time. In generalThree-phase AC asynchronous motorIn the same circuit, the current value of the overload protection action is smaller than the overcurrent, but both are smaller than the short-circuit protection action current. It is worth mentioning that short circuit protection, overcurrent protection and overload protection can not be replaced by each other.
Three-phase AC asynchronous motorOverload protection should use thermal relays or motor protectors as protective elements.
