    安(an)(an)全是鐵(tie)路(lu)運輸的(de)(de)永恒主題。隨著鐵(tie)路(lu)運行(xing)列車向(xiang)高(gao)速、重載、安(an)(an)全、智能化的(de)(de)快速發(fa)展,鐵(tie)路(lu)通信(xin)(xin)信(xin)(xin)號系(xi)(xi)統(tong)(tong)的(de)(de)安(an)(an)全性、可靠性尤(you)為重要(yao)(yao),要(yao)(yao)求也越來(lai)越高(gao)。因(yin)此對(dui)配套系(xi)(xi)統(tong)(tong)軟硬件的(de)(de)要(yao)(yao)求更加細化、完善、嚴(yan)格。應用于鐵(tie)路(lu)信(xin)(xin)號系(xi)(xi)統(tong)(tong)的(de)(de)鐵(tie)路(lu)數(shu)字(zi)信(xin)(xin)號電(dian)(dian)纜(lan),對(dui)保障鐵(tie)路(lu)信(xin)(xin)號系(xi)(xi)統(tong)(tong)的(de)(de)安(an)(an)全正常運行(xing)至關重要(yao)(yao)。因(yin)此,應提(ti)高(gao)電(dian)(dian)纜(lan)的(de)(de)傳輸性能穩定性與抗外界(jie)電(dian)(dian)磁場干(gan)擾能力,避免因(yin)電(dian)(dian)纜(lan)因(yin)素造成系(xi)(xi)統(tong)(tong)故(gu)障而影響行(xing)車安(an)(an)全。

    在鐵路數字信號(hao)電(dian)纜的(de)制造過程中,應從以下幾個(ge)方(fang)面(mian)進(jin)行質量控制:

    合(he)理(li)的指導性文(wen)件

    鐵路數字信(xin)號電纜指(zhi)導(dao)性(xing)工(gong)(gong)藝技術文件(jian)的(de)制定依據是TB/T3100《鐵路數字信(xin)號電纜》及(ji)其后續的(de)修改單以及(ji)標準(zhun)中(zhong)規定的(de)規范性(xing)引(yin)用文件(jian)。指(zhi)導(dao)性(xing)的(de)工(gong)(gong)藝技術文件(jian)、作業指(zhi)導(dao)書、檢(jian)驗檢(jian)測文件(jian)必須具備準(zhun)確性(xing)、指(zhi)導(dao)性(xing)、可操作性(xing),文件(jian)需細化(hua)至產(chan)品實現的(de)每(mei)一(yi)個操作及(ji)控制要(yao)點(dian)、每(mei)一(yi)個工(gong)(gong)藝參數,能(neng)夠指(zhi)導(dao)完成(cheng)產(chan)品的(de)工(gong)(gong)藝過(guo)程及(ji)檢(jian)驗檢(jian)測,能(neng)夠指(zhi)導(dao)實現產(chan)品標準(zhun)中(zhong)所規定和(he)各項(xiang)性(xing)能(neng)指(zhi)標,并(bing)嚴格按質(zhi)量體(ti)系的(de)要(yao)求對文件(jian)資料進行(xing)管理。

    優質(zhi)的(de)原材料

    鐵路數字信(xin)號電纜所用的(de)(de)銅線坯、絕(jue)緣料(liao)(liao)、銅鋁帶等主要原(yuan)(yuan)材料(liao)(liao),直接決定(ding)(ding)了電纜的(de)(de)電氣性能(neng)和(he)機械物(wu)理(li)性能(neng)。原(yuan)(yuan)材料(liao)(liao)的(de)(de)選(xuan)型與質量控(kong)制(zhi)是先決條件,是產(chan)品(pin)質量控(kong)制(zhi)的(de)(de)基(ji)礎。因此,應(ying)(ying)按(an)(an)產(chan)品(pin)的(de)(de)技(ji)術要求(qiu)選(xuan)擇理(li)想的(de)(de)原(yuan)(yuan)材料(liao)(liao),對進廠原(yuan)(yuan)材料(liao)(liao)應(ying)(ying)按(an)(an)檢驗(yan)規(gui)范逐批進行檢測,確保投(tou)入(ru)的(de)(de)原(yuan)(yuan)材料(liao)(liao)合格;絕(jue)緣材料(liao)(liao)、銅帶、鋁帶等關(guan)鍵材料(liao)(liao)在使用和(he)存放過程(cheng)中(zhong),應(ying)(ying)防止污染(ran)、氧(yang)化、受潮;有使用期限的(de)(de)原(yuan)(yuan)材料(liao)(liao)應(ying)(ying)在規(gui)定(ding)(ding)的(de)(de)有效期內(nei)使用;各(ge)種絕(jue)緣材料(liao)(liao)的(de)(de)標志、標識一定(ding)(ding)要明確、準(zhun)確,防止混用。

    完好的(de)生(sheng)產設備

    各生產設備應(ying)(ying)確(que)保(bao)完好,應(ying)(ying)能保(bao)證實現產品(pin)(pin)持(chi)續穩定(ding)的(de)(de)(de)加(jia)工能力(li),設備中的(de)(de)(de)產品(pin)(pin)通道應(ying)(ying)確(que)保(bao)產品(pin)(pin)不被磨損、刮(gua)傷(shang)、擠壓(ya)變(bian)形(xing)、過(guo)度(du)彎(wan)曲等,張力(li)機構(gou)應(ying)(ying)穩定(ding)可(ke)靠(kao),避免因張力(li)失控而造(zao)成的(de)(de)(de)產品(pin)(pin)質量(liang)缺陷;設備的(de)(de)(de)溫度(du)、壓(ya)力(li)、速(su)度(du)、長(chang)度(du)、直(zhi)徑及(ji)同心度(du)、電容、火花檢(jian)測(ce)等儀器(qi)儀表及(ji)傳感(gan)器(qi)應(ying)(ying)計量(liang)準確(que)、顯示清晰、便于觀察,應(ying)(ying)按(an)其相應(ying)(ying)的(de)(de)(de)規(gui)定(ding)及(ji)要(yao)求(qiu)經常清理(li)維護,并定(ding)期進行檢(jian)定(ding)、校驗(yan)。

    重要的自(zi)檢(jian)互(hu)檢(jian)

    電纜生(sheng)產制(zhi)造(zao)過(guo)程(cheng)中的(de)自檢(jian)與(yu)(yu)互(hu)(hu)檢(jian)非常重(zhong)要(yao),生(sheng)產作(zuo)業人(ren)員通(tong)過(guo)自檢(jian)與(yu)(yu)互(hu)(hu)檢(jian)掌握本(ben)工序(xu)各班次之(zhi)間(jian)的(de)質量動態(tai)、了解(jie)差異(yi)、及(ji)時修正并排除,有利于產品(pin)的(de)一致性(xing);也可(ke)以通(tong)過(guo)自檢(jian)與(yu)(yu)互(hu)(hu)檢(jian)銜接上(shang)下道(dao)工序(xu),保證產品(pin)的(de)正確性(xing),防止不合格品(pin)流入下道(dao)工序(xu)造(zao)成產品(pin)的(de)不合格及(ji)更大的(de)損失。

    嚴格的出廠把關

    產(chan)品的(de)(de)檢(jian)測(ce)(ce)(ce)主要(yao)有生產(chan)過程中各工(gong)序質量控制的(de)(de)專(zhuan)檢(jian)及(ji)成品的(de)(de)出廠把關檢(jian)測(ce)(ce)(ce)。首先,各檢(jian)測(ce)(ce)(ce)儀(yi)(yi)表(biao)(biao)應(ying)按(an)規定(ding)(ding)的(de)(de)期限及(ji)要(yao)求進行(xing)檢(jian)定(ding)(ding)校驗(yan),確保(bao)檢(jian)測(ce)(ce)(ce)儀(yi)(yi)器、儀(yi)(yi)表(biao)(biao)的(de)(de)完好(hao)準確狀態,確保(bao)檢(jian)測(ce)(ce)(ce)數(shu)據具(ju)有一定(ding)(ding)的(de)(de)真實性、可靠性、重復(fu)性,其次(ci),檢(jian)測(ce)(ce)(ce)人(ren)員應(ying)熟知儀(yi)(yi)器儀(yi)(yi)表(biao)(biao)的(de)(de)操作規程,并嚴格按(an)檢(jian)驗(yan)作業指(zhi)導書(shu)的(de)(de)規定(ding)(ding)進行(xing)規范(fan)的(de)(de)檢(jian)測(ce)(ce)(ce)作業及(ji)儀(yi)(yi)表(biao)(biao)維護;另外,檢(jian)測(ce)(ce)(ce)儀(yi)(yi)表(biao)(biao)用(yong)電(dian)源電(dian)壓的(de)(de)穩定(ding)(ding)性、儀(yi)(yi)表(biao)(biao)的(de)(de)有效接(jie)地、檢(jian)測(ce)(ce)(ce)的(de)(de)環境溫度、電(dian)磁干擾及(ji)儀(yi)(yi)表(biao)(biao)自(zi)身溫度等(deng)都(dou)會影響檢(jian)測(ce)(ce)(ce)數(shu)據的(de)(de)真實準確性,檢(jian)測(ce)(ce)(ce)過程中應(ying)具(ju)體分析,排除(chu)因(yin)環境因(yin)素及(ji)儀(yi)(yi)表(biao)(biao)自(zi)身的(de)(de)不穩定(ding)(ding)因(yin)素所造(zao)成的(de)(de)檢(jian)測(ce)(ce)(ce)數(shu)據的(de)(de)不確定(ding)(ding)性。
