概述
FN5-12R(L)型戶內(nèi)交流高壓負(fù)荷開(kāi)關(guān)-熔斷器組合電器是我廠吸收消化過(guò)外先進(jìn)技術(shù)，結(jié)合我國(guó)的供電要求，自行設(shè)計(jì)研制而成的。該產(chǎn)品經(jīng)全面型式試驗(yàn)和長(zhǎng)期的試運(yùn)行考核，性能達(dá)到IEC420《交流高壓負(fù)荷開(kāi)關(guān)-熔斷器組合電器》（1990版）和GB3804《3-63kV交流高壓負(fù)荷開(kāi)關(guān)》標(biāo)準(zhǔn)要求，與國(guó)外同類產(chǎn)品比較，技術(shù)參數(shù)已經(jīng)達(dá)到同類產(chǎn)品水平，具有體積小、重量輕，可用于環(huán)網(wǎng)柜和箱式變電站，廣泛用于12kV線路的電能分配，并有效地避免了設(shè)備的缺相運(yùn)行。
該產(chǎn)品的研制成功填補(bǔ)了國(guó)內(nèi)空白，可實(shí)現(xiàn)開(kāi)關(guān)、隔離和接地三工位。
