DC Converter Transformers for Electrified Railways - TРДТНП-16000/110 Ж

Designed for DC electric drives of large rolling mills, excitation systems of synchronous electric machines, including powerful turbo- and hydro generators, aluminium, copper, chlorine electrolysis plants, etc. Rectifiers parameters - current up to 100 kA, voltages from 12 to 20000 V. The main rectification schemes are zero and bridge, with the connection schemes of transformer windings usually having the following connections Y(D)/Ynr-Ynr-0-6(5-11) and Y(D)/D-Y-11-0(0-1) respectively. Complex conversion schemes are also used when it is necessary to reduce the ripple of rectified voltage and current and to improve the utilisation of semiconductor gates. Voltage regulation is carried out both built-in and realised on a separate autotransformer, by means of on-load tap-changers and off-load tap-changers in a wide range from 5% to 100%, including equal regulation stages. Thanks to the design features, the quality of electrical energy is ensured - the requirements on the level of distortion...
