摘 要：殼式變壓器較芯式變壓器來(lái)講，在耐受雷電沖擊及抗短路方面有其優(yōu)越性。設(shè)計(jì)了一種330 kV三繞組有載調(diào)壓高阻抗殼式變壓器，針對(duì)該產(chǎn)品容量過(guò)小且絕緣等級(jí)高，造成電場(chǎng)集中，變壓器空間過(guò)小，從而使繞組結(jié)構(gòu)、絕緣結(jié)構(gòu)、引線結(jié)構(gòu)均較為復(fù)雜的情況，對(duì)技術(shù)參數(shù)、設(shè)計(jì)方案、產(chǎn)品結(jié)構(gòu)特點(diǎn)及設(shè)計(jì)中的關(guān)鍵技術(shù)進(jìn)行了分析與介紹，試驗(yàn)結(jié)果表明，該產(chǎn)品符合IEC標(biāo)準(zhǔn)及合同要求，且運(yùn)行狀況良好。
關(guān)鍵詞：殼式變壓器；高阻抗；高電壓；開(kāi)發(fā)設(shè)計(jì)

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
