What is electronic Motor Protector
Electronic motor protectors have evolved from transistors to integrated circuits to date, and have been developed into micro-processing chip thick-mode circuits. They are generally divided into phase-off protection, comprehensive protection (multi-function protection), temperature protection and intelligent protection. The protector has the advantages of energy saving, sensitive action, high precision, shock and vibration resistance, good repeatability, complete protection function and low power consumption.
1. The motor protector (motor protector) is based on the principle of detecting line current changes (including taking, positive sequence, negative sequence, zero sequence and overcurrent) to detect phase failure or overload signals. In addition to the phase failure protection function, it also has overload and stall protection functions.
2.Intelligent protection: It integrates protection, telemetry, communication, remote control and integrated motor protection device to protect the motor from phase failure, overload, short circuit, undervoltage, overvoltage and leakage. It also has current and voltage display, time. Control, software self-diagnosis, call self-recovery, self-start sequence, fault memory, self-contained and remote transmission alarm, display current and voltage faults at the time of fault, flashing alarm with code, configure RS485 communication interface, realize computer networking. At the same time, it can monitor and monitor the functions of 256 motors.
