DHGJ-4-50/170A系列多極管式滑觸線

滑(hua)觸線的(de)(de)結構形式多樣(yang)，但(dan)總的(de)(de)原理如(ru)下(xia)：移(yi)(yi)(yi)動(dong)(dong)(dong)(dong)設(she)備(bei)(bei)(bei)由(you)于移(yi)(yi)(yi)動(dong)(dong)(dong)(dong)，需要不(bu)斷地(di)變換位置，在每(mei)一(yi)個不(bu)同的(de)(de)位置上，移(yi)(yi)(yi)動(dong)(dong)(dong)(dong)設(she)備(bei)(bei)(bei)又(you)(you)要隨時能獲得動(dong)(dong)(dong)(dong)力(li)電(dian)源(yuan)，否則就無法繼(ji)續(xu)移(yi)(yi)(yi)動(dong)(dong)(dong)(dong)。這(zhe)(zhe)時，滑(hua)觸線就應運而生了(le)。我們沿著(zhu)移(yi)(yi)(yi)動(dong)(dong)(dong)(dong)設(she)備(bei)(bei)(bei)的(de)(de)運行(xing)軌道平(ping)行(xing)敷了(le)若干條導體，接通電(dian)源(yuan)。在移(yi)(yi)(yi)動(dong)(dong)(dong)(dong)的(de)(de)設(she)備(bei)(bei)(bei)上，我們又(you)(you)安裝上可(ke)以從導體上取(qu)電(dian)的(de)(de)集(ji)(ji)電(dian)器。這(zhe)(zhe)樣(yang)，當設(she)備(bei)(bei)(bei)移(yi)(yi)(yi)動(dong)(dong)(dong)(dong)時，集(ji)(ji)電(dian)器隨設(she)備(bei)(bei)(bei)同步運行(xing)，并隨時從導體上取(qu)得電(dian)源(yuan)，提供(gong)給設(she)備(bei)(bei)(bei)，以使設(she)備(bei)(bei)(bei)可(ke)繼(ji)續(xu)移(yi)(yi)(yi)動(dong)(dong)(dong)(dong)。這(zhe)(zhe)些導體和集(ji)(ji)電(dian)器組成的(de)(de)裝置就稱作(zuo)滑(hua)觸線。

根據用(yong)電設備的不同，滑觸(chu)(chu)(chu)線有(you)多種形式，如地鐵(tie)，是用(yong)通道側面的鋼(gang)軌做滑觸(chu)(chu)(chu)線，工礦企業的橋式吊車是用(yong)三條角鋼(gang)作為三相滑觸(chu)(chu)(chu)線。

滑觸(chu)線(xian)主要用(yong)于各種起重(zhong)運(yun)(yun)輸機械(xie)，生產流水線(xian)等需移動(dong)供電的設(she)施(shi)和場所，如起重(zhong)機、裝卸橋、電動(dong)葫蘆(lu)、立(li)體倉(cang)庫、游(you)樂(le)設(she)備、空(kong)調(diao)檢測線(xian)等，廣泛應用(yong)在起重(zhong)運(yun)(yun)輸、電力(li)、造船、港口、冶金(jin)、礦山、水廠(chang)、環保、化工、家電、汽車、服裝、煙酒、游(you)樂(le)等眾多行業。

安(an)(an)全(quan)滑(hua)(hua)(hua)觸(chu)(chu)線(xian)(xian)是一種新型移動供電(dian)(dian)(dian)(dian)裝置(zhi)，以其絕緣、安(an)(an)全(quan)、耐溫、抗振、節能等優越性(xing)能逐步(bu)替代了舊式裸露角(jiao)鐵及銅(tong)排滑(hua)(hua)(hua)觸(chu)(chu)線(xian)(xian)。安(an)(an)全(quan)滑(hua)(hua)(hua)觸(chu)(chu)線(xian)(xian)由填(tian)嵌在(zai)工(gong)(gong)(gong)程塑料型管(guan)或槽(cao)板中(zhong)(zhong)的光滑(hua)(hua)(hua)平整的T2銅(tong)排或嵌有(you)(you)耐磨(mo)(mo)導體(ti)的鋁型材作為(wei)載流體(ti)，組合(he)成(cheng)輸(shu)電(dian)(dian)(dian)(dian)導管(guan)，導管(guan)下有(you)(you)開(kai)口槽(cao)以利集(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)運行，并(bing)由集(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)的高耐磨(mo)(mo)銅(tong)基石(shi)墨(mo)電(dian)(dian)(dian)(dian)刷將電(dian)(dian)(dian)(dian)力導向工(gong)(gong)(gong)作電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)。 安(an)(an)全(quan)滑(hua)(hua)(hua)觸(chu)(chu)線(xian)(xian)的使(shi)用為(wei)車間帶來(lai)了安(an)(an)全(quan)，但也有(you)(you)缺點，橋式起重機(ji)在(zai)使(shi)用中(zhong)(zhong)易(yi)斷(duan)電(dian)(dian)(dian)(dian)，有(you)(you)時(shi)在(zai)輸(shu)電(dian)(dian)(dian)(dian)導管(guan)內產生火花，嚴(yan)重時(shi)滑(hua)(hua)(hua)觸(chu)(chu)線(xian)(xian)某(mou)放(fang)炮"，造成(cheng)集(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)更換過(guo)于頻(pin)繁，影響生產。為(wei)此，進(jin)行了如下改進(jin)：（1）增大集(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)電(dian)(dian)(dian)(dian)刷倒(dao)角(jiao)，并(bing)打磨(mo)(mo)光滑(hua)(hua)(hua)；（2）增加(jia)(jia)集(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)兩相對電(dian)(dian)(dian)(dian)刷間彈(dan)簧強度、彈(dan)性(xing)，保(bao)證(zheng)彈(dan)簧恢(hui)復自如；（3）加(jia)(jia)深。加(jia)(jia)固集(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)中(zhong)(zhong)的彈(dan)簧座，保(bao)證(zheng)電(dian)(dian)(dian)(dian)刷的恢(hui)復彈(dan)簧在(zai)工(gong)(gong)(gong)作中(zhong)(zhong)不(bu)易(yi)"串(chuan)位(wei)"；（4）兩段(duan)安(an)(an)全(quan)滑(hua)(hua)(hua)觸(chu)(chu)線(xian)(xian)連(lian)接處(chu)連(lian)接塊要(yao)有(you)(you)倒(dao)角(jiao)，保(bao)證(zheng)集(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)平滑(hua)(hua)(hua)過(guo)渡。同(tong)時(shi)，為(wei)保(bao)證(zheng)安(an)(an)全(quan)滑(hua)(hua)(hua)觸(chu)(chu)線(xian)(xian)的正常(chang)使(shi)用，行車工(gong)(gong)(gong)的規范操作、維修工(gong)(gong)(gong)的定期保(bao)養、定期檢(jian)查也*。

四、供電方式

   在考(kao)(kao)慮安(an)全滑觸(chu)線供(gong)(gong)(gong)電(dian)點(dian)的同時應考(kao)(kao)慮同跨(kua)滑觸(chu)線的用電(dian)設備(bei)的總臺數(shu)總容(rong)量，任務工作制和全線長(chang)度的電(dian)壓降值，及環境（電(dian)壓降計(ji)(ji)算可根據前面導軌參(can)(can)數(shu)表的數(shu)據計(ji)(ji)算）。供(gong)(gong)(gong)電(dian)一般有以下幾種供(gong)(gong)(gong)用戶參(can)(can)考(kao)(kao)：①單端(duan)供(gong)(gong)(gong)電(dian)；②中(zhong)部(bu)(bu)供(gong)(gong)(gong)電(dian)；③兩端(duan)供(gong)(gong)(gong)電(dian)；④兩端(duan)1/6處(chu)供(gong)(gong)(gong)電(dian)；⑤兩端(duan)正/10處(chu)和中(zhong)部(bu)(bu)三點(dian)供(gong)(gong)(gong)電(dian)等。

五、安裝說明
   在安裝滑觸線前先將角鋼支架按照用戶選擇的安裝形式，根據滑觸線的懸掛間距固定好，在安裝現場把每6米一根的滑觸線上套上所需的懸掛座，和兩端接頭護套各一個，還在一端裝上鋁接頭一個，裝鋁接頭時應注意只能將鋁導軌伸進接頭的1/2留給另一根導軌連接用，以上工作準備好后，再把一根一根的滑觸線懸掛在支架上，進行全線連接，連接時應擰緊每個接頭的螺絲。在滑觸線全線長超過200米時應加裝伸縮裝置（伸縮裝置本廠隨時供應），在引接電源線進線時，可在每6米一根的接頭處引接，具體接法可參照前面接頭裝置圖。
   在安裝彎道滑觸線時，懸吊距離應相應縮短，具體尺寸可根據現場條件而定。
   在安裝導電器時先把導電器裝在配套的(de)方管上，選擇與滑觸線(xian)(xian)配合的(de)適當位置(zhi)固(gu)定(ding)在用電設備上，應注意為使導電器與滑觸線(xian)(xian)有(you)很(hen)好(hao)的(de)跟(gen)蹤性能和良好(hao)的(de)接(jie)觸能力，導電器與滑觸線(xian)(xian)應安裝在同一垂(chui)直、水(shui)平方向。

六、維護保養   

    安全滑觸線在正常運行中應做定期檢查，因為用電設備是每個工礦企業的主要生產工具，稍有差錯就會直接影響工廠的生產效益。在檢查滑觸線時應檢查每6米一個接頭處是否有松動、脫開，在檢查導電器時，應檢查活動部位是否轉動靈活，拉簧是否疲勞，電刷磨損等情況（這些情況都會影響到滑觸線導電性能和導電器的跟蹤性能。應及時作好調整）。
   節假(jia)日設備整(zheng)修期，將導電(dian)器脫(tuo)出(chu)(chu)導管，檢查(cha)導電(dian)器電(dian)刷(shua)滾輪(lun)磨(mo)損(sun)情況，如電(dian)刷(shua)伸出(chu)(chu)量小于規定有效長度(du)時(shi)，要(yao)及時(shi)更換(huan)，導向滾輪(lun)變形嚴重時(shi)，亦需(xu)更換(huan)，以保持導電(dian)器運行(xing)正(zheng)常和(he)電(dian)刷(shua)的(de)良好(hao)接觸，并清查(cha)造成的(de)原因(yin)。安全滑觸線(xian)所(suo)有零(ling)部件中(zhong)，電(dian)刷(shua)是*正(zheng)常會磨(mo)損(sun)的(de)零(ling)件。
