The motor protector brings great convenience to the management of industrial production process control. The equipment adopts high-speed integrated high-speed processor for data acquisition and processing. Based on the realization of traditional low-voltage motor protection, it integrates measurement, control, measurement and operation. Recording and communication functions, truly digital, intelligent, networked, protection, measurement and control, with small size, light weight, powerful, high reliability, flexible configuration, beautiful appearance, easy installation.
The function of the motor protector is to protect the motor's one-sided surface. In the motor, overcurrent, undercurrent, phase failure, stall, short circuit, overvoltage, undervoltage, leakage, three-phase unbalance, overheating, grounding protection, bearing wear, When the rotor is fair, the alarm or protection is installed. The perfect motor protector is a comprehensive installation of collecting, calculating, analyzing, monitoring, alarming and controlling various operational information data in the motor running history.
At present, the design of the integrated motor protector on the market mainly adopts the scheme of AC sampling mode + high-performance single-chip microcomputer. The motor protector adopting the design method has many measurement parameters, high measurement precision, and can provide more perfect protection functions, but adopts this The cost of the design method is high, and the selling price is also high. There is no cost performance when it is only necessary to provide overload and break equal basic fault protection for the motor. Therefore, a simple design and functions can meet the basic protection requirements, and are mainly used for Motor protectors that replace thermal relays will have a large market. Kaimin motor protector adopts low-cost design scheme, which can accurately display and trip the various types of faults encountered in the operation of the motor, which can effectively prevent the accidental burning of the motor and save a lot of users. The funds are an ideal replacement for thermal relays. Therefore, the widespread use of motor protectors can not only improve the accuracy and scientificity of process control, reduce the accident rate, but also play a positive role in improving the automation level of the electric control system and developing the national economy.
