GY106 Motor Control Protector

GY106 is a all-round motor intelligent monitoring protectors which are applying the imported integrated circuits, intellectual property rights patented technology and software copyright. It protects and controls the motor by microprocessor and supports the feeder protection to complete the motor operation, autodiagnosis, communication with upper computer and so on.Its measure protection avoided the productive accidents caused by the motor fault like overload , locked-rotor, overvoltage, undervoltage, underload, open-phase, electrical grounding earth etc.,and ensured the equipments ' normal function and safety .
This motor protector is a intergrated device which can collect,calculate,analyze,monitor,alarm and control all kinds of signals from the functioning motor. The device completes the fast correct protection through the fault alarming,protecting action and the action time delay setting to ensure the production safety, and complete the real-time monitoring in the upper computor for the fuctioning motor's slender information. The device will send out limit alarming before the equipment may cause serious fault so that the managerial staff can deal with the fault in time to avoid the unexpected stop making influence to the normal production and maximize the effectiveness of equipment operation and control. When the motor's working parameters reach the set alarming value,the protection device just do the alarming but will not do the tripping.When the working parameters reach the set tripping value,the device will enter the tripping delay time.The tripping action will be cancelled if the equipment return to the normal function within the set tripping delay time.But the tripping action will be carried out if over the tripping delay time,the motor will be power off. Every kinds of protection information will update to the computor manage system through the communication interface while the device do every protection function.
                                                                                         Basic protection function                                              
start-up protection: Only do the protection for the open-phase,overvoltage. Undervoltage,short-circuit and three phase unbalance,overtime start-up within the start-up time.
overvoltage protection: Will function within 6s when the working voltage is bigger than the set value(factory default value is 260V) 
undervoltage protection: Will function within 6s when the working voltage is smaller than the set value(factory default value is 180V) 
open-phase protection: when any phase is power off,function time≤2.0s
locked-rotor protection: when the working current reached the multiples of the set value, function time≤2.0s
unbalance protection: when any two phase's current difference reached the set percentage,function time≤2.0s
underload protection: When the working current is continuously smaller than the set underload limit, function time≤2.0s.
leakage protection: When the zero sequance tansformer detected the leakage current reached the set value, function time≤1.0s.(factory default value is 1) 
Short-circuit protection: when the short-circuit current value reached 5 multiples of the set leakage current value, function time≤2.0s
overload protection: overload protection function time is inverse-time protection or tripping protection,function time
