Wind Inverter High Power Variable Crowbar Braking Resistor

The Power of the Braking resistors: Pr=P0/ΔK=P1×(1-0.2)×η/ΔK
P0:The power of the Motor
ΔK:Braking resistor allows multiple over load in
short-term work,Specific numerical value according to the condition check chart
P1:Average braking power
η:Transmission efficiency,Drive mechanical system in
braking,provide and efficiency corresponding brake damping.
0.2:Motor resistance consumes 20% braking energy.
Brake rate: 100s
operation as a cycle,braking time percentage according to brake current Udc/R and the braking ratio ED to choose brake unit.
