Motor protection Motor protection

Motor protection is www.dongfeng-motor.com to give comprehensive protection,that is,in the motor overload,open phase,locked-rotor,short circuit,overvoltage,undervoltage,electric leakage,three-phase imbalance,overheating,Bearing wear using the rotor eccentricity and axial channeling,radial runout,shall report to the police or protection;For motor protection device is a motor protector,including thermal relay generator stator core Apparatus,electronic protector and intelligent protector is present large and important motor generally adopts the intelligent protection device.The differential protection www.dongfeng-motor.com Motor differential protection with differential quick break protection and with or without second harmonic brake complex percentage differential protection,can be used in the three largest side of the differential current input (three times),for an equipment voltage current analog and switch quantity of powerful collection complete,equipped with standard RS485 and stator industry CAN communication,and communication Through the rational allocation of main transformer differential protection implemented three times,two main transformer differential protection,two laps with a variable differential protection and generator differential protection,differential protection and the electric motor Protection of protection and control functions.
