變壓器/電機投退涌流及過電壓抑制應用場景
變壓(ya)(ya)器(qi)(qi)在(zai)(zai)空載(zai)投入時(shi)產(chan)生(sheng)勵磁涌(yong)流對設(she)備(bei)損害(hai)巨大，且在(zai)(zai)投退時(shi)產(chan)生(sheng)的操作過(guo)電(dian)壓(ya)(ya)會(hui)對設(she)備(bei)絕(jue)(jue)緣造(zao)成較大破壞；電(dian)動(dong)(dong)機(ji)在(zai)(zai)退出時(shi)也會(hui)產(chan)生(sheng)極大的操作過(guo)電(dian)壓(ya)(ya)，破壞電(dian)動(dong)(dong)機(ji)絕(jue)(jue)緣，故(gu)此兩種設(she)備(bei)投退時(shi)頻發安(an)全(quan)事故(gu)。針對新(xin)建(jian)、改(gai)建(jian)、擴(kuo)建(jian)項目合閘涌(yong)流及操作過(guo)電(dian)壓(ya)(ya)問題，可在(zai)(zai)變壓(ya)(ya)器(qi)(qi)電(dian)源側安(an)裝(zhuang)Spark- T裝(zhuang)置(zhi)，在(zai)(zai)電(dian)動(dong)(dong)機(ji)前端安(an)裝(zhuang)Spark-B裝(zhuang)置(zhi)，如下圖(tu)。
利用(yong)(yong)Spark-T裝置可(ke)有效(xiao)抑(yi)制變壓(ya)(ya)(ya)器(qi)空(kong)載合閘涌流(liu)及操作(zuo)(zuo)過電壓(ya)(ya)(ya)，利用(yong)(yong)Spark-B裝置可(ke)有效(xiao)抑(yi)制電動機的操作(zuo)(zuo)過電壓(ya)(ya)(ya)，利用(yong)(yong)兩種(zhong)裝置可(ke)以極大(da)提高(gao)設備(bei)的安全性、穩定性。
