摘 要:為解決農(nóng)村電網(wǎng)電壓不合格問題,研制了一款新型電力智能調(diào)壓器。該調(diào)壓器采用新型自耦變壓器、有載分接開關(guān)及線路自動監(jiān)測與控制技術(shù)等,具有調(diào)節(jié)擋位多、精細調(diào)節(jié)、用戶無瞬間斷電等特點。有載分接開關(guān)采用機械傳動裝置,機械開關(guān)采用間歇式傳動機構(gòu),且通過加裝SSRA電子開關(guān)實現(xiàn)觸頭無燃弧開合,大大增強了使用壽命和運行的安全性。
關(guān)鍵詞:變壓器;電力智能調(diào)壓器;傳動機構(gòu);有載分接開關(guān)

Abstract: In order to solve the problem of unqualified voltage in rural power grid, this paper developed a new type of intelligent electric voltage regulator, which adopted a new type of autotransformer, on-load tap-changer, line automatic monitoring and control technology etc, with many advantages, such as adjusting the number of gears, adjusting the precision, and no instantaneous power failure etc features. The on-load tap-changer adopted mechanical transmission and the mechanical switch adopted the intermittent-type transmission mechanism. The SSRA electronic switch was added to realize the contact non-arc opening and closing, which greatly enhances the safety of service life and operation.
Key words: transformer; electric power intelligent voltage regulator; transmission mechanism; on-load tap-changer
