FDZ2/10-1.7-1W放電線圈

• 本型放電線圈系單相戶內(nèi)、戶外裝置，環(huán)氧樹脂絕緣的全封閉產(chǎn)品與高壓并聯(lián)電容器組并聯(lián)連接，當(dāng)電容器組與系統(tǒng)斷開后，能在5s 內(nèi)將電容器組上的剩余電壓由 2 Un 降至50V 以下。在正常運(yùn)行時(shí)，二次繞組可以作電壓指示，剩余繞組接成開口三角，當(dāng)電容器極間局部發(fā)生故障時(shí)，會(huì)產(chǎn)生零序電壓，驅(qū)動(dòng)繼電保護(hù)裝置。本型放電線圈特點(diǎn)為體積小，重量輕、無局部放電、抗過電壓能力強(qiáng)、空載損耗小，空載電流小、防污能力強(qiáng)、使用安裝方便、免維護(hù)，是替代油浸式放電線圈的*產(chǎn)品。
• This type of discharge coil is single-phase,cast resin insulated used indoors or outdoors connected with high voltage parallel connection capacitor group.When the capacitor group is cut off from the system,it can take only five second to reduce the residual voltage of the capacitor group from 2Un to below 50V.When operating normal,the secondary winding is used as voltage indicator and the residual winding is connected as split triangle.If the pole of capacitor partial breaks down,it would bring the zero sequence voltage to drive relay protection gear.The product is small,light,little partial discharge energy and high resistance to over voltge,It is a new product for superseding the oil type discharge coil．
