Excitation transformer
At present, the excitation transformers used in the excitation systems of large-scale hydropower and thermal power units mainly have the following insulation types in terms of insulation methods: resin-cast dry-type transformers with epoxy resin as insulation materials; non-alkali glass fiber winding impregnated transformers; Dry-type transformers; MORA-type dry-type transformers; NOMEx-type dry-type transformers; new synthetic grease oil stained transformers. Among the above-mentioned insulation methods of transformers, the two insulation methods of resin casting and winding dry are the most widely used at present. In the excitation systems of the Three Gorges 700Mw unit and the Longtan 700Mw unit, the dry type of epoxy resin insulation material is used. transformer
