汽車線束使用損壞的原因分析

Release time:2020-10-08 Number of hits:1672

【摘要】汽車線束換導(dǎo)線時(shí)未按規(guī)定選用導(dǎo)線(導(dǎo)線過細(xì)),大電流通過時(shí)產(chǎn)生較大壓降而發(fā)熱,致使導(dǎo)線表皮逐漸老化損壞;

          1.汽車線束換導(dǎo)線時(shí)未按規(guī)定選用導(dǎo)線(導(dǎo)線過細(xì)),大電流通過時(shí)產(chǎn)生較大壓降而發(fā)熱,致使導(dǎo)線表皮逐漸老化損壞;

          2.安裝蓄電池時(shí)粗心大意,正、負(fù)極性接反,交流發(fā)電機(jī)內(nèi)短路、各絕緣墊片及絕緣套損壞,交流發(fā)電機(jī)磁場線和搭鐵線接反等均會(huì)引起線束燒毀;

          3.汽車線束常采用薄鐵皮卡固定,其邊緣鋒利有如刀口,并且鐵皮卡表面又未加絕緣措施,車輛在長期行駛中振動(dòng)、顛簸,電源線束難免被磨壞、割破而搭鐵,造成線束燒毀;

汽車線束

          4.汽車線束臨時(shí)連接電氣設(shè)備時(shí),未搞清熔斷器電流進(jìn)、出口,即隨意引出電源線,或熔斷器燒損后,未按要求換相同規(guī)格的熔斷器,或用粗銅絲代替熔斷器,失去保護(hù)作用而燒毀線束;

          5.電流表的兩接柱常采用塑料絕緣套,塑料散熱差,既要承受電流,又要承受顛簸和振動(dòng),若電流表接線松動(dòng)或接觸不好,就會(huì)導(dǎo)致溫度上升,導(dǎo)致塑料燒熔而搭鐵,造成汽車線束的燒毀;

          6.接柱連接不牢靠,產(chǎn)生較大的壓降而發(fā)熱,時(shí)間久了,絕緣墊片就會(huì)損壞而搭鐵短路。注意電流表及其他儀表后的接柱要連接好,另外固定在車架接線板上的導(dǎo)線連接螺釘也不宜過長,以免搭鐵而燒毀線束。
