A tape special DC converter transformer design methodology ice melting apparatus

The present invention is a special converter transformers with direct current ice melting apparatus design method. Comprising the steps of 1) determining melting ice covers the circuit means; 2) preselected current ice melting wire; 3) determining the maximum allowed current conductor; 4) Calculation of DC power at a preselected pressure drop and ice-melting current; 5) determining nominal parameters ice melting apparatus ; 6) calculates the ideal no-load direct voltage; 7) calculates commutation reactors valve side rated voltage; 8) calculating converter transformer commutating reactance side rated voltage; 9) calculates the AC side of the converter rated current; 10) is calculated commutating reactor inductance; 11) calculates the rated capacity of the converter transformer; 12) calculating the inductance converter transformer; 13) or TSR TCR determining the rated capacity and current branch; 14) determining a total value of the TCR or TSR inductive branch; 15) determining the TCR or TSR branches need to increase the inductance value; 16) determining a zero power circuit inductance; 17) determining the minimum allowable current zero power; 18) AC filter design.
