The daily maintenance content of the motor protector mainly lies in three aspects: daily maintenance, process inspection and regular inspection. Daily maintenance requires different adjustments based on the actual protector usage and location, and cannot be generalized.
1. The body surface of the motor protector needs to be kept clean. Excessive dust on the surface will easily reduce the overall insulation resistance of the protector and cause malfunctions. Especially in some dusty workplaces, this point needs to be paid attention to daily.
2. Check whether the output and input terminals, contacts or plug-ins of the motor protector are in good contact from time to time? Is there any phenomenon such as overheating of the body and damage of the connecting line due to poor contact? Are the installation positions of the protector and the connector firmly maintained?
3. Observe whether the display status of the indicator light, digital tube or LCD screen of the protector is normal?
4. Is the set current value consistent with the original set value? Especially protectors that use potentiometer knobs and dial switches to operate devices are easy to change the original set value due to the random adjustment of the operator.
