熔斷器的短路保護(hù)性能好，過(guò)載保護(hù)性能一般。如確需在過(guò)載保護(hù)中使用，需要仔細(xì)匹配線路過(guò)載電流與熔斷器的額定電流。熔斷器的選擇主要依據(jù)負(fù)載的保護(hù)特性和短路電流的大小選擇熔斷器的類型。對(duì)于容量小的電動(dòng)機(jī)和照明支線，常采用熔斷器作為過(guò)載及短路保護(hù)，所以希望熔體的熔化系數(shù)適當(dāng)小些。一般選用鉛錫合金熔體的RQA系列熔斷器。對(duì)于較大容量的電動(dòng)機(jī)和照明干線，則應(yīng)著重考慮短路保護(hù)和分?jǐn)嗄芰?。一般選用具有較**斷能力的RM10和RL1系列的熔斷器；當(dāng)短路電流很大時(shí)，宜采用具有限流作用的RT0和RTl2系列的熔斷器。

在春檢停電檢修時(shí)應(yīng)對(duì)熔斷器做如下內(nèi)容的檢查：靜、動(dòng)觸頭接觸是否吻合，緊密完好，有否燒傷痕跡。熔斷器轉(zhuǎn)動(dòng)部位是不是靈活，是不是銹蝕、轉(zhuǎn)動(dòng)不靈等異常，零部件是不是損壞、彈簧有否銹蝕。熔體本身有否受到損傷，經(jīng)長(zhǎng)期通電后有無(wú)發(fā)熱伸長(zhǎng)過(guò)多變得松弛無(wú)力。熔管經(jīng)多次動(dòng)作管內(nèi)產(chǎn)氣用消弧管是否燒傷及日曬雨淋后是否損傷變形、長(zhǎng)度是不是縮短。清掃絕緣子并檢查有無(wú)損傷、裂紋或放電痕跡，拆開(kāi)上、下引線后，用2500V搖表測(cè)試絕緣電阻應(yīng)大于300MΩ。檢查熔斷器上下連接引線有無(wú)松動(dòng)、放電、過(guò)熱現(xiàn)象。對(duì)上述項(xiàng)目檢查出的缺點(diǎn)一定要認(rèn)真檢修處理。
