style="text-indent:25px">產(chǎn)品質(zhì)量引起的故障在農(nóng)網(wǎng)改造中當(dāng)時(shí)由于需求的配電箱數(shù)量大、施工期短，配電箱廠需要有關(guān)低壓電器的供貨時(shí)間急且數(shù)量多，因而產(chǎn)生了對產(chǎn)品質(zhì)量的要求不嚴(yán)格的現(xiàn)象，造成了一些產(chǎn)品投入運(yùn)行后不久就發(fā)生故障。如有些型號交流接觸器在配電箱投運(yùn)后不久，就因3接觸器合閘線圈燒壞，而無法運(yùn)行。配電箱內(nèi)電器選擇不當(dāng)引起的故障由于在制造時(shí)對交流接觸器容量選擇不很恰當(dāng)，對不同出線回路安裝同容量的交流接觸器，且未考慮到三相負(fù)荷的不平衡情況，而未能將部分出線接觸器電流等級在正常選擇型號基礎(chǔ)上，提高一個(gè)電流等級選擇 </p><p style="text-indent:25px">常見故障原因 1．1環(huán)境溫度對低壓電器影響引起的故障配電箱中的低壓電器，由熔斷器、交流接觸器、剩余電流動作保護(hù)器、電容器及計(jì)量表等組成。周圍空氣溫度的上限不超過40℃；周圍空氣溫度24h的平均值不超過35℃；周圍空氣溫度的下限不低于-5℃或-25℃。農(nóng)網(wǎng)改造的配電箱在室外運(yùn)行，它不但受到陽光的直接照射產(chǎn)生高溫，同時(shí)運(yùn)行中自身也會產(chǎn)生熱量，所以在盛夏高溫季節(jié)，箱體內(nèi)的溫度將會達(dá)到60℃以上，這時(shí)的溫度**超過了這些電器規(guī)定的環(huán)境溫度
