    摘 要:殼式變壓器較芯式變壓器來講,在耐受雷電沖擊及抗短路方面有其優(yōu)越性。設計了一種330 kV三繞組有載調壓高阻抗殼式變壓器,針對該產品容量過小且絕緣等級高,造成電場集中,變壓器空間過小,從而使繞組結構、絕緣結構、引線結構均較為復雜的情況,對技術參數(shù)、設計方案、產品結構特點及設計中的關鍵技術進行了分析與介紹,試驗結果表明,該產品符合IEC標準及合同要求,且運行狀況良好。
    關鍵詞:殼式變壓器;高阻抗;高電壓;開發(fā)設計

    Abstract: Shell transformers are superior to core transformers in terms of resistance to lightning shock and short circuit.This paper designed a kind of 330 kV on-load voltage regulation high impedance shell-type transformer with three windings.Aiming at the conditions of too small capacity and high insulation grade, resulting in the concentration of electric field, too small transformer space, to make the windings structure, insulation structure and lead structure more complex, this paper analyzed and introduced the technical parameters, design scheme, characteristics of product structure and the key technologies in design.The result of the experiment shows that this product conforms to the IEC standard and the contact requirement, with good operational state.
    Key words: shell-type transformer; high impedance; high voltage; research and design
