intelligent high voltage variable load phase advancer

intelligent high voltage variable load phase advancer
Product Detailed
accurate compensation for changing-load motor for 75kw---10000kw AC wire-coiling motor man-machine display control system

 Intelligent high voltage variable load phase advancer & compensation equipment

    

range of application

Successfully applied in  Three Georges project, national engineering designing institute, mining company, cement mill, stell mill,sugar factory,wood industry, chemical industry, city planning, and other place with big power motor and high electric consume place.

  It applicable for 75kw--10000kw  wound rotor asynchronous motor reactive power local compensation and power save.

especially for places where always working in changing-load condition.

Adopt double CPU control and adjusting the related parameters according to changing load , realize dynamic compensation  and make power factor in optimal state all the time

decrease the stator current and winding temperature rising, improving power factor and efficiency, to reduce the loss of the motor and power system.

   

 characteristic

increase motor power factor to over 0.95---0.99;

reduce reactive power more than 60%

reduce motor stator current 10-20%;

save line loss and copper loss 20-30%

environment temperatue: -40C---+50C

relative humidity of air no exceed 90%

 it is a New invention in national field of changing load motor  compensation control.

independent working system from motor, can adjust and maintenance without stop the motor

Automatic tracking rotor current ,for constant torque load and changing torque load

 with function of malfucntion record, over current, low voltage, less phase, outer fault, communication failure, parameter mistake protetion

Friendly man-machine interface, LCD screen interface , simple operation, with reliable and all-round automatic fault protection function without influence on production in paintenance and take-care .

can take back the cost within half a year

standard of conformity: GB3797; Q/XWZ11-2066

 when motor work in load , rotor current is l2e, stator current is l1e, drawing as above

U: voltage vector; l1 stator current vector ; l2 rotor current vector; lm exciting current vector;

l1e stator current rated vector; l2e rotor current rated vector; Φ1 motor rated power angle factor
