HIGH-VOLTAGE POWER TRANSFORMER WITH DOLIUK DISTRIBUTION SCREEN (DS)

摘要

The invention relates to electric engineering and may be used in power transformers and reactors of 110...750...1200 kV. A distributing screen (DC) is used as a shunt which takes part of pulse current (for example, a half of current) in case of overvoltage so reducing in this way coils pulse overvoltage drop. This allows reducing size of between-coils insulation and growing reliability of transformers with DC. This invention adds to embodiments of DC to Patent of Ukraine № 73849 decreasing laboriousness of production the last ones.
