GY102The Motor Intelligent Monitoring and Protection Device is a crystallization of accumulated experience in the development and production of motor protection devices and microcomputer protection devices, combined with modern technology. The Motor Intelligent Monitoring and Protection Device, produced using integrated circuits and proprietary technology, as well as software copyrights, features a fieldbus interface. It is controlled by a microprocessor to execute motor protection and control, and supports feeder protection, completing operations such as motor operation, self-diagnosis, and communication with the host computer. It provides measurement protection for motors, avoiding production accidents caused by faults such as overloading, stalling, overvoltage, undervoltage, light load, phase failure, three-phase imbalance, and grounding, thereby maximizing the effectiveness of equipment operation.
A comprehensive motor protector collects, calculates, analyzes, monitors, alarms, and controls various operational data of the motor during its operation. By utilizing fault alarms, protective actions (release mechanisms), and setting action delays, it achieves immediate and accurate protection, ensuring normal production. This protector can also communicate data information to enable real-time monitoring of the motor's operating status on a higher-level computer, providing management information through data processing. Before equipment potential faults occur, over-limit alarms can promptly remind management personnel to address them, avoiding unnecessary downtime and impacting normal production, thereby maximizing the effectiveness of equipment operation and control. When the motor operating parameters reach the preset warning values, the protective device only issues a warning without triggering the release mechanism; however, when the over-limit value reaches the preset release value, the protective device enters a release trigger delay period. If the equipment returns to normal operation within the preset release delay time, the release action is canceled; otherwise, the protective device sends a release signal to drive the actuator, cutting off power and stopping the motor. While the motor control device implements various protection functions, the protective information is also generated by the device and transmitted to the computer management system via communication interfaces.
