The basic safety device of the core "motor" of the industrial site

Update:08-05-2023
The motor is the core equipment of the industrial site, and its safe operation is directly related to the production efficiency and quality. In order to ensure the safe operation of the motor, it is necessary to configure some basic safety devices, such as overload relay, thermal relay, short circuit protector, grounding protector, etc. These safety devices can cut off the power supply in time when the motor is abnormal, so as to avoid greater losses and dangers. The overload relay is used to protect the motor from overload or stalling. When the motor load exceeds the rated value, the overload relay will act to stop the motor. The thermal relay is used to protect the motor from overheating. When the temperature of the motor exceeds the set value, the thermal relay will act to stop the motor. The short-circuit protector is used to protect the motor from short-circuit. When the motor circuit is short-circuited, the short-circuit protector will act to stop the motor. The grounding protector is used to protect the motor from the influence of the ground fault. When the ground fault occurs in the motor line, the grounding protector will act to stop the motor.
