style="text-indent:25px">跌落式熔斷器的安裝和運(yùn)行維護(hù)：跌落式熔斷器瓷件應(yīng)良好，熔絲管不應(yīng)有吸潮膨脹、彎曲變形現(xiàn)象。熔絲管上下觸頭的中心線與熔絲管軸線應(yīng)在同一平面內(nèi)，不得扭歪。跌落式熔斷器應(yīng)安裝牢固、排列整齊，不得左右轉(zhuǎn)動，10kV跌落式熔斷器相間水平距離不應(yīng)小于0.5m。為便于操作和熔絲熔斷時(shí)自跌，使熔絲管軸線有一定傾斜度，瓷座軸線與地面垂線的夾角一般為20°~30°。分、合閘操作應(yīng)靈活、可靠，接觸緊密。合閘前調(diào)整上下觸頭應(yīng)有一定的壓縮行程。在運(yùn)行中，跌落式熔斷器熔絲熔斷3~4次后，應(yīng)檢查熔絲管內(nèi)徑是否增大，如果增大2~3mm,則應(yīng)考慮更換新的熔絲管。在運(yùn)行中如發(fā)現(xiàn)跌落式熔斷器分、合閘不靈活、則應(yīng)立即檢修調(diào)整。</p><p> 熔絲不正常熔斷熔絲熔斷引起掉管，從理論上說是熔絲保護(hù)起到了作用。但是，從往年的統(tǒng)計(jì)圖表中可明顯地看出，不正常熔斷有時(shí)間規(guī)律和氣候規(guī)律，反映在每年的7～8月間，氣溫高、用電負(fù)荷大、配變負(fù)載上升快，熔絲熔斷掉管故障集中多發(fā)。這說明了熔絲不正常熔斷，其原因有：(1)熔絲容量與配變?nèi)萘颗渲貌划?dāng)，達(dá)不到熔絲配置的技術(shù)標(biāo)準(zhǔn)。(2)熔絲的質(zhì)量不過關(guān)，熔斷特性比較差。熔絲軋斷從往年的統(tǒng)計(jì)圖表中還可看出，熔絲由于軋傷引起掉管沒有特別的時(shí)間規(guī)律和氣候規(guī)律，而從熔絲本體軋斷的部位來分析，發(fā)現(xiàn)一是熔絲兩端固定的螺栓處，二是熔絲在熔絲管兩端的金屬鑄件轉(zhuǎn)角處。
