WVP motor compensation device controller cabinet

Specifications

Model: high voltage motor compensation device controller cabinet 

1)range of application

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.

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.

2) Unique feature:

1: WVP is national patented products

2:accurate compensation according to actual loading situation

3: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

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

3)characteristic

1:high efficiency

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%

2: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

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

4: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 .

 5:can take back the cost within half a year

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

relative humidity of air no exceed 90%

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

Φ2  after compensation power angle factor
