GY600 motor protector


Product Overview


Motor protection device is researched and developed to protect and control motor with high performance digital microprocessor technology, based on the research of similar products abroad and summary of MCC electrical system home.The motor protection device possess international advanced protection function, support professional way of motor control and provide accurate monitoring function, can run for a variety of motor control, monitoring, protection, interlock, measure, remote communication, remote communication, remote control, fault information management.
The motor protection device is a kind of multi-functional protector, greatly improve the design and the production efficiency and reduces the user site debugging and maintenance cost,, so as to improve the scene of the scientific and effective protection of the production process, the measurement and control unit, which is protected by intellectual property and software copyright.
Motor protection device adopt modular design structure, with those advantages of small in size, compact structure, guide rail or the self-contained bolt installation, suitable for various kinds of stationary and drawer cabinet where can be installed directly to use.Apply to three-phase asynchronous motor and motor protection control, motor production device is the best ideal products for many fields such as chemical, petroleum, electric power, mining, coal, metallurgy, municipal, paper making, the nuclear industry involving three-phase motor protection.

Overload control protection When the motor overload carrying, control protection device track and calculate overload current according to the heat capacity (Q) of the motor thermal.  In thermal overload protection fully considered in the calculation of the motor stator and rotor temperature rise, meanwhile considering the unbalanced three-phase affect motor heatin. When the current increases to control protection value, giving alarm prompt action to trip value time.
Underload (flow) protection when protected current through less than the setting value, action set alarm, and give the alarm or stop work.
Motor Shaft Lock Protection To prevent the occurrence of severe motor running blockage or motor overload operation while the multiple of current reach setting current, give signal alarm or stop
Unbalance protection of three-phase current Through three phase current or three-phase voltage according to the ratio of the minimum line current and maximum line current alarms when the set values for the reach or exceed hint to trip condition
Open-phase protection When any phase in three phase current in the current ratio is greater than the imbalance Angle value is defined as the phase failure fault
Over voltage protection Monitor three-phase voltage values, any phase voltage higher than the set value alarm prompt in action time
Low voltage protection Monitor three-phase voltage values, any phase voltage lower than the set value alarm prompt in action time
ground protection Through external zero sequence current transformer measurement, according to  the current of motor phase the conductor (PE) or (PEN) whether to start the leakage fault protection function, when greater than the setting values of the leakage protection device, protective device sends an alarm to trip time
Anti-interference protection monitor continuously the voltage of the equipment, when the system voltage instantaneous fall then recover, motor can restart
Start timeout protection Continuously monitor the starting current delay time, when the current is greater than the delay time to complete the boot device, three phase current was 1.2 times greater than the set current start timeout tripping protection action
Reverse protection When detect three-phase voltage phase sequence is not correct, stop and can not start the motor
External fault protection When check the external switch input signal and the default state of switch input  is inconsistent, the device can not start
