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.
