DESIGNING OF SERIES DIFFRENCE PROTECTOR FOR EAF TRANSFORMER
Mingqiang Chen · Hunan Metallurgy · 2001
A EAF transformer shall be broken easy by a breakdowns of the voltage series difference while its air switchs is operated frequently as a result of the voltage of EAF transformer is abjeused largely in a melting process. A design about the series difference protector for its contral lines of the EAF transformer was introduced in this paper. The protector can control the operations effectively and avoid breaking of the EAF transformer.
