overview

The motor protection and measurement device is an intelligent, networked, and digital low-voltage motor protection and measurement device developed in accordance with IEC international standards; It has changed the traditional mode of motor protection and controlThe formula replaces conventional electrical components such as thermal relays, current transformers, intermediate relays, and transmitters, fully realizing the integration of protection, measurement, and control while incorporating advanced network communication technologyIntegrating distributed intelligent technology into MCC control center; This provides a scientifically effective on-site protection and measurement unit for industrial production process control.It has multiple digital protection functions such as overload, current imbalance, grounding/leakage, undercurrent, locked rotor, undervoltage, overvoltage, underpower, and startup acceleration timeout, meeting the requirements of direct startup and dual protectionStarting methods such as directional starting, star/delta starting, etc;Rich recording function, which can record the instantaneous values of parameters when multiple faults occur, guiding fault analysis;Flexible protection function configuration, convenient for users to balance safety production and continuous production;The protection control module and display operation unit adopt a separate installation structure, making installation/maintenance extremely flexible;Realize the measurement of various electrical parameters such as three-phase current and grounding current in the motor circuit;It can achieve network communication with RTU, PLC, and various microcomputer industrial control configuration software (iFIX, WinCC, Intouch, Kingview, MCGS) to form a distributed comprehensive power monitoring system.
