Wind Power Application
Shinenergy wind power transformer in the power grid is for pressuring change and isolating the power grid of the three harmonic equipment, protect the heating and insulation materials to reduce the life of the generator.
The function of control transformer in fan control circuit: the control circuit is usually isolated from the main circuit by control transformer. The voltage used in the control circuit is different from main circuit. The main circuit voltage may be 380V, while the control loop can be 220V, which is not affected by the loop voltage. Thus, the insulation level requirements in the control circuit can be reduced.
