| Abstract: | In this paper, the design of relay protection system for main transformers of the 330 kV substation is studied. The corresponding backup protection system is designed to address all kinds of faults which are not covered by the main protection system. A design scheme of fixed water spray automatic fire extinguishing system for transformers is proposed,which can effectively reduce the risk of transformer fire. This paper can provide reference for the related research design and implementation of the same type of main transformer protection system. |
