1000A單極滑觸線銅膨脹段選項表

1000A單極滑觸線銅膨脹段系統1.包括插入一根6米長的滑導線中的一級滑動部件 2.重疊在一起的銅條可以作為滑導線的接觸面，而且可以保證導電的連續性。
銅桿在滑套3中滑動，從而起到機械的導向作用和可靠電接觸。
大間隙為200mm 每個膨脹系統由一導體護套4和一接口護套5給予保護。在接口護套的兩端內扣裝一端蓋！ 

膨脹段原理分析與描述

膨(peng)(peng)(peng)(peng)脹(zhang)(zhang)(zhang)段(duan)(duan)是(shi)根據滑(hua)觸(chu)(chu)(chu)線(xian)(xian)(xian)(xian)(xian)在(zai)不同溫度(du)環(huan)境工(gong)作(zuo)的(de)(de)情況下，對滑(hua)觸(chu)(chu)(chu)線(xian)(xian)(xian)(xian)(xian)在(zai)熱脹(zhang)(zhang)(zhang)冷縮(suo)(suo)(suo)時(shi)(shi)(shi)(shi)所(suo)產(chan)生的(de)(de)直線(xian)(xian)(xian)(xian)(xian)形變(bian)（型  材擠壓對頂）和(he)(he)(he)冷縮(suo)(suo)(suo)時(shi)(shi)(shi)(shi)（型材收(shou)縮(suo)(suo)(suo)）而(er)造成(cheng)(cheng)(cheng)斷電(dian)(dian)(dian)而(er)設(she)計(ji)的(de)(de)。它由兩個可(ke)移動(dong)(dong)(dong)段(duan)(duan)與滑(hua)觸(chu)(chu)(chu)線(xian)(xian)(xian)(xian)(xian)干線(xian)(xian)(xian)(xian)(xian)本(ben)(ben)(ben)體(ti)直截串聯連接(jie)而(er)成(cheng)(cheng)(cheng)，其(qi)基本(ben)(ben)(ben)原(yuan)理為：它由相(xiang)(xiang)對的(de)(de)靜(jing)態(tai)滑(hua)片和(he)(he)(he)動(dong)(dong)(dong)態(tai)滑(hua)片疊插(cha)組成(cheng)(cheng)(cheng)一個與滑(hua)觸(chu)(chu)(chu)線(xian)(xian)(xian)(xian)(xian)本(ben)(ben)(ben)體(ti)截面(mian)相(xiang)(xiang)吻合的(de)(de)過(guo)渡(du)體(ti)，在(zai)滑(hua)觸(chu)(chu)(chu)線(xian)(xian)(xian)(xian)(xian)環(huan)境溫度(du)變(bian)化時(shi)(shi)(shi)(shi)可(ke)自由地進行直線(xian)(xian)(xian)(xian)(xian)移動(dong)(dong)(dong)。由于(yu)(yu)(yu)靜(jing)態(tai)滑(hua)片和(he)(he)(he)動(dong)(dong)(dong)態(tai)滑(hua)片疊插(cha)后(hou)，無論怎樣伸展與收(shou)縮(suo)(suo)(suo)，它都能(neng)夠給集(ji)電(dian)(dian)(dian)器(qi)的(de)(de)電(dian)(dian)(dian)刷一個直線(xian)(xian)(xian)(xian)(xian)過(guo)渡(du)的(de)(de)平(ping)面(mian)，從而(er)克服了較早時(shi)(shi)(shi)(shi)期膨(peng)(peng)(peng)(peng)脹(zhang)(zhang)(zhang)接(jie)頭而(er)帶(dai)來的(de)(de)膨(peng)(peng)(peng)(peng)脹(zhang)(zhang)(zhang)范圍(wei)窄，集(ji)電(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)刷跨越困難而(er)造成(cheng)(cheng)(cheng)斷電(dian)(dian)(dian)，接(jie)觸(chu)(chu)(chu)面(mian)變(bian)小(xiao)而(er)跳火等故(gu)障。由于(yu)(yu)(yu)靜(jing)態(tai)滑(hua)片和(he)(he)(he)動(dong)(dong)(dong)態(tai)滑(hua)片兩端與滑(hua)線(xian)(xian)(xian)(xian)(xian)本(ben)(ben)(ben)體(ti)直截連接(jie)后(hou)，同時(shi)(shi)(shi)(shi)又(you)設(she)置(zhi)兩根滑(hua)動(dong)(dong)(dong)導(dao)桿將靜(jing)態(tai)滑(hua)片和(he)(he)(he)動(dong)(dong)(dong)態(tai)滑(hua)片穿插(cha)導(dao)向(xiang)，因此，它具有良好的(de)(de)同軸度(du)。與此同時(shi)(shi)(shi)(shi)，在(zai)靜(jing)態(tai)滑(hua)片和(he)(he)(he)動(dong)(dong)(dong)態(tai)滑(hua)片兩端的(de)(de)上方(fang)還設(she)置(zhi)兩根與滑(hua)接(jie)片相(xiang)(xiang)并聯的(de)(de)軟電(dian)(dian)(dian)纜，從而(er)穩(wen)定和(he)(he)(he)增加該膨(peng)(peng)(peng)(peng)脹(zhang)(zhang)(zhang)段(duan)(duan)的(de)(de)載流量，使整個系統(tong)不致(zhi)于(yu)(yu)(yu)因膨(peng)(peng)(peng)(peng)脹(zhang)(zhang)(zhang)段(duan)(duan)的(de)(de)設(she)置(zhi)而(er)影(ying)響(xiang)整線(xian)(xian)(xian)(xian)(xian)額定載流量 .膨(peng)(peng)(peng)(peng)脹(zhang)(zhang)(zhang)段(duan)(duan)的(de)(de)可(ke)伸縮(suo)(suo)(suo)范圍(wei)可(ke)在(zai) 0~200mm之間調節，可(ke)以吸收(shou)滑(hua)線(xian)(xian)(xian)(xian)(xian)導(dao)軌本(ben)(ben)(ben)體(ti)材料為鋁、銅，膨(peng)(peng)(peng)(peng)脹(zhang)(zhang)(zhang)點(dian)距離150米/段(duan)(duan)、周邊環(huan)境溫度(du)－40℃～＋115℃時(shi)(shi)(shi)(shi)，所(suo)產(chan)生膨(peng)(peng)(peng)(peng)脹(zhang)(zhang)(zhang)系數而(er)引發(fa)的(de)(de)伸縮(suo)(suo)(suo)距離,并使集(ji)電(dian)(dian)(dian)器(qi)能(neng)順(shun)暢通過(guo)而(er)不影(ying)響(xiang)其(qi)供(gong)電(dian)(dian)(dian)質量。
