近幾年，我國的跌落式熔斷器產(chǎn)品的整體性能有著明顯的提升，同時(shí)制造企業(yè)的生產(chǎn)技術(shù)與加工工藝都向著期望的方向發(fā)展，跌落式熔斷器產(chǎn)品的品種與規(guī)格都在逐漸完善中，對(duì)于產(chǎn)品的**技術(shù)也在不斷摸索中，國內(nèi)的企業(yè)在發(fā)展中不斷吸收發(fā)達(dá)國家的先進(jìn)技術(shù)，更新改造新的技術(shù)，同時(shí)對(duì)產(chǎn)品大膽的創(chuàng)新，產(chǎn)品的整體適應(yīng)性加強(qiáng)，能滿足國內(nèi)不同工況的需求，改善了工藝的不足之處，生產(chǎn)的產(chǎn)品符合很高的質(zhì)量水平，同時(shí)產(chǎn)品的各項(xiàng)性能接近于國際水平。我們知道跌落式熔斷器被廣多用于電力、石油、化工、環(huán)保、造紙、汽車、船舶等行業(yè)，是其電力系統(tǒng)中不可缺少的保護(hù)元件之一，為設(shè)備提供強(qiáng)有力的保護(hù)，間接的推動(dòng)著我國工業(yè)的發(fā)展，同時(shí)保障工業(yè)生產(chǎn)的可靠性與電力系統(tǒng)的穩(wěn)定性，為各行業(yè)的正常運(yùn)作有著重要的作用。 </p> <p> <br /> </p> <p> <br /> </p><p style="text-indent:25px">高壓跌落式熔斷器三相的操作順序。停電操作時(shí)，應(yīng)先拉中間相，后拉兩邊相。送電時(shí)則先合兩邊相，后合中間相。停電時(shí)先拉中相的原因主要是考慮到中相切斷時(shí)的電流要小于邊相(電路一部分負(fù)荷轉(zhuǎn)由兩相承擔(dān))，因而電弧小，對(duì)兩邊相無危險(xiǎn)。操作第二相(邊相)跌落式熔斷器時(shí)，電流較大，而此時(shí)中相已拉開，另兩個(gè)跌落式熔斷器相距較遠(yuǎn)，可防止電弧拉長造成相間短路。遇到大風(fēng)時(shí)，要按先拉中間相，再拉背風(fēng)相，之后拉迎風(fēng)相的順序進(jìn)行停電。送電時(shí)則先合迎風(fēng)相，再合背鳳相，末尾合中間相，這樣能夠防止風(fēng)吹電弧造成短路。熔斷器的維護(hù)方面應(yīng)該注意什么？</p><div
