跟著我國現代化進程的(de)(de)(de)不斷(duan)(duan)加速，電(dian)力(li)資源現已進入(ru)人(ren)們(men)日(ri)子的(de)(de)(de)方(fang)(fang)方(fang)(fang)面面，成(cheng)為人(ren)們(men)賴以日(ri)子、出產的(de)(de)(de)根底，對整(zheng)個電(dian)網的(de)(de)(de)作(zuo)(zuo)業(ye)提出了更高的(de)(de)(de)要求。跌(die)落(luo)式(shi)熔(rong)(rong)(rong)(rong)斷(duan)(duan)器廣泛(fan)用于35kV及以下(xia)的(de)(de)(de)配(pei)電(dian)線路分(fen)支線和配(pei)電(dian)變(bian)壓器上(shang)，作(zuo)(zuo)業(ye)時能供給的(de)(de)(de)明顯斷(duan)(duan)開(kai)點，熔(rong)(rong)(rong)(rong)管內置的(de)(de)(de)熔(rong)(rong)(rong)(rong)絲，使其具有了作(zuo)(zuo)為輸配(pei)電(dian)線路和配(pei)電(dian)變(bian)壓器的(de)(de)(de)過載和短路維護以及分(fen)合額定(ding)電(dian)流(liu)的(de)(de)(de)效果。但幾年來連續(xu)發生的(de)(de)(de)幾起(qi)電(dian)力(li)出產事端，是在人(ren)員拉合跌(die)落(luo)式(shi)熔(rong)(rong)(rong)(rong)斷(duan)(duan)器操作(zuo)(zuo)不當所構成(cheng)，就此翻開(kai)對遙控跌(die)落(luo)式(shi)熔(rong)(rong)(rong)(rong)斷(duan)(duan)器的(de)(de)(de)研發和運用，旨在保證供電(dian)可(ke)靠性的(de)(de)(de)一(yi)同(tong)減(jian)少人(ren)工操作(zuo)(zuo)，完(wan)畢電(dian)力(li)作(zuo)(zuo)業(ye)自動(dong)化。

1、對傳統手動跌落式(shi)熔斷器(qi)的(de)運用(yong)辦(ban)法的(de)分析

近(jin)年以來，我國的(de)中(zhong)低壓配網發(fa)展(zhan)迅速，大量的(de)跌落式熔斷器被設備于35kV及以下(xia)配電變壓器(qi)上，因為自身功用和結(jie)構所致，成為電力(li)行業作業者(zhe)在作業中接觸(chu)最多(duo)(duo)，被操作次數最多(duo)(duo)的(de)電力(li)設備(bei)之一(yi)。在進行傳統(tong)跌落式(shi)熔斷(duan)器的操作(zuo)時，根據(ju)跌落式熔斷器(qi)裝(zhuang)設(she)的(de)方位來挑選(xuan)不(bu)同(tong)長度的(de)絕(jue)緣(yuan)(yuan)(yuan)操(cao)作(zuo)(zuo)(zuo)桿(gan)(gan)，由操(cao)作(zuo)(zuo)(zuo)人(ren)抬高至熔管(guan)操(cao)作(zuo)(zuo)(zuo)扣環處(chu)擺開或取(qu)下熔管(guan)。在實踐中常常發生因熔管(guan)多年沒有操(cao)作(zuo)(zuo)(zuo)，部件(jian)老化過(guo)火嚴(yan)峻，上部動、靜觸頭之間(jian)出(chu)現(xian)銹蝕粘合的(de)情(qing)況，這時(shi)(shi)(shi)(shi)候(hou)依托(tuo)人(ren)力無(wu)法取(qu)下熔管(guan)，究(jiu)竟只好(hao)將整(zheng)段(duan)線路進(jin)行(xing)停(ting)(ting)電(dian)處(chu)理，增(zeng)大了(le)停(ting)(ting)電(dian)范圍；有時(shi)(shi)(shi)(shi)出(chu)現(xian)人(ren)工操(cao)作(zuo)(zuo)(zuo)時(shi)(shi)(shi)(shi)熔斷器(qi)裝(zhuang)設(she)方位過(guo)高，現(xian)場僅有的(de)絕(jue)緣(yuan)(yuan)(yuan)操(cao)作(zuo)(zuo)(zuo)桿(gan)(gan)長度無(wu)法滿足高度要求、或絕(jue)緣(yuan)(yuan)(yuan)操(cao)作(zuo)(zuo)(zuo)桿(gan)(gan)過(guo)長而操(cao)作(zuo)(zuo)(zuo)人(ren)員進(jin)行(xing)運用時(shi)(shi)(shi)(shi)十分困難(nan)的(de)情(qing)況；也發生過(guo)現(xian)場作(zuo)(zuo)(zuo)業人(ren)員一時(shi)(shi)(shi)(shi)心急，爬至裝(zhuang)設(she)臺架上運用操(cao)作(zuo)(zuo)(zuo)桿(gan)(gan)，存在電(dian)氣(qi)安(an)全距離缺少(shao)，導致人(ren)員觸電(dian)的(de)危險現(xian)象，遇(yu)到雨天等惡劣氣(qi)候(hou)條件(jian)下的(de)操(cao)作(zuo)(zuo)(zuo)時(shi)(shi)(shi)(shi)難(nan)以進(jin)行(xing)。以上情(qing)況在實踐出(chu)產(chan)作(zuo)(zuo)(zuo)業中時(shi)(shi)(shi)(shi)有發生，跌落式熔斷(duan)器的(de)(de)運用對(dui)電網(wang)的(de)(de)作業(ye)(ye)供給了便利(li)快捷，但近年(nian)來不斷(duan)添加的(de)(de)新裝電力用戶(hu)數，日益偏重(zhong)的(de)(de)供電可靠性，以及電力員(yuan)工的(de)(de)安全作業(ye)(ye)需求，這(zhe)些都對(dui)跌落式熔斷器的運用(yong)功率提出了更高的要(yao)求。

2、遙控(kong)跌落式熔斷器簡介

遙控跌落式熔斷器的運(yun)用(yong)，旨在(zai)處理戶外10kV配電(dian)線路(lu)和配電(dian)變(bian)壓器(qi)變(bian)電(dian)站(zhan)一(yi)次側對(dui)熔斷(duan)器(qi)投、切操(cao)作(zuo)(zuo)，遙動分合且(qie)三相一(yi)同(tong)斷(duan)開、合閘功(gong)用(yong)，完(wan)畢(bi)操(cao)作(zuo)(zuo)安全性的意圖。不(bu)只完(wan)畢(bi)了分、合閘遙控(kong)自動化，一(yi)同(tong)減(jian)輕勞動強度與操(cao)作(zuo)(zuo)難(nan)度。

3、遙控跌落式熔斷(duan)器作業原理

遙控（現場遙控器或通(tong)過其他(ta)端口到體系(xi)后(hou)臺）宣告指令，電(dian)(dian)子驅動特種(zhong)直(zhi)流旋(xuan)轉電(dian)(dian)動機(ji)(ji)。由電(dian)(dian)動機(ji)(ji)推進耐高壓的推拉桿，跟(gen)著電(dian)(dian)動機(ji)(ji)正(zheng)轉或回轉帶動旋(xuan)轉力臂向上向下(xia)運(yun)動來(lai)完畢跌落式熔(rong)斷器的電(dian)動分閘(zha)與合(he)閘(zha)。

現(xian)場遙控(kong)操(cao)作器的作業(ye)原理：選(xuan)用單(dan)片機控(kong)制(zhi)和數字(zi)濾波電路(lu)，運用遠紅外(wai)通訊完畢近距離（20m內）控制跌落熔(rong)斷器分、合，抗干擾(rao)能力強(qiang)，操(cao)(cao)作安(an)穩可靠。遙控器帶暗碼鎖，具有(you)(you)防誤操(cao)(cao)作和自維護功(gong)用。當地遙控操(cao)(cao)作具有(you)(you)暗碼敞開優先性。

遠(yuan)程遙控操作的(de)作業原理：充分運用智能化配(pei)電(dian)臺區現(xian)有的(de)用電(dian)負荷處理終端（遠(yuan)程抄表(biao)終端），在(zai)后臺開宣告跌落式熔斷器(qi)處理(li)模塊，該操(cao)(cao)(cao)作(zuo)(zuo)(zuo)(zuo)(zuo)模塊分為(wei)遠(yuan)程(cheng)(cheng)后(hou)臺(tai)操(cao)(cao)(cao)作(zuo)(zuo)(zuo)(zuo)(zuo)和手機提(ti)示(shi)操(cao)(cao)(cao)作(zuo)(zuo)(zuo)(zuo)(zuo)兩部分。遠(yuan)程(cheng)(cheng)后(hou)臺(tai)操(cao)(cao)(cao)作(zuo)(zuo)(zuo)(zuo)(zuo)通(tong)(tong)過(guo)暗(an)(an)碼進(jin)入遠(yuan)程(cheng)(cheng)操(cao)(cao)(cao)作(zuo)(zuo)(zuo)(zuo)(zuo)界面，為(wei)了安全起見，完畢二次暗(an)(an)碼供認(ren)發送操(cao)(cao)(cao)作(zuo)(zuo)(zuo)(zuo)(zuo)指(zhi)(zhi)令，進(jin)入當地臺(tai)區(qu)終端(duan)宣告指(zhi)(zhi)令電子(zi)驅(qu)動分合閘。手機提(ti)示(shi)操(cao)(cao)(cao)作(zuo)(zuo)(zuo)(zuo)(zuo)是(shi)當地處理(li)電工(gong)通(tong)(tong)過(guo)撥打后(hou)臺(tai)專(zhuan)用操(cao)(cao)(cao)作(zuo)(zuo)(zuo)(zuo)(zuo)電話，根據現場(chang)情況通(tong)(tong)過(guo)語(yu)音提(ti)示(shi)進(jin)行手機操(cao)(cao)(cao)作(zuo)(zuo)(zuo)(zuo)(zuo)，手機操(cao)(cao)(cao)作(zuo)(zuo)(zuo)(zuo)(zuo)的指(zhi)(zhi)令通(tong)(tong)過(guo)后(hou)臺(tai)與處理(li)終端(duan)完畢直接通(tong)(tong)訊，到達現場(chang)遙控操(cao)(cao)(cao)作(zuo)(zuo)(zuo)(zuo)(zuo)的意圖。手機提(ti)示(shi)操(cao)(cao)(cao)作(zuo)(zuo)(zuo)(zuo)(zuo)要進(jin)行暗(an)(an)碼安全認(ren)證(zheng)。

4、遙控跌落式熔斷器與傳統(tong)手動(dong)跌落式熔(rong)斷器(qi)比較具有的優越性

（1）遙(yao)控熔斷器(qi)不只能運用絕緣棒手動(dong)操(cao)作(zuo)，一同還能線控、現場遙(yao)控或手機和電(dian)腦后臺控制操(cao)作(zuo)，脫離高壓電(dian)分、合閘，使人(ren)身安全有保證。

（2）不受風、雨、霧、雪氣候和夜間操作(zuo)影響(xiang)，全天候操作(zuo)。

（3）不受操作(zuo)人員操作(zuo)水平緩熟練程(cheng)度致使設(she)備損壞(huai)和(he)束縛供電功(gong)率。

（4）分合閘(zha)準確到位，不需登高爬攀，簡略(lve)便利(li)。

（5）由(you)所以(yi)帶(dai)鎖功用變壓(ya)器被盜發生，免于人為破壞電力設(she)施(shi)和竊電險情(qing)。

（6）具有(you)預(yu)案(an)前(qian)沿性，變壓器(qi)及線(xian)路老化一旦發生災情隨時堵截電源。

（7）智能檢測(ce)體系可(ke)實(shi)時查看(kan)變壓器(qi)臺(tai)區(qu)用電情況(kuang)，在缺(que)(que)點時回(hui)傳(chuan)缺(que)(que)點信息，并在需(xu)求時自動堵截缺(que)(que)點線路。

（8）三相(xiang)同步(bu)分閘，處(chu)理了拉弧(hu)危險處(chu)無弧(hu)情況(kuang)操作(zuo)。

畢竟，為(wei)使遙控跌落式熔斷器更可靠、安全(quan)的作(zuo)業，除加強(qiang)日常的巡視查看外，也因留意以(yi)下(xia)幾點：

熔(rong)斷器熔(rong)絲的限流值(zhi)要(yao)恰當，保(bao)證發生缺點時能及時堵截缺點，維護同(tong)線路其(qi)他設備。（2）對每(mei)次的操(cao)作前后時應仔細查看(kan)跌落熔斷(duan)器(qi)外觀、絕(jue)(jue)緣(yuan)瓷瓶無裂紋(wen)，必要時運用絕(jue)(jue)緣(yuan)搖(yao)表(biao)進行絕(jue)(jue)緣(yuan)實驗，在分合后應供認熔斷(duan)器(qi)上靜觸(chu)頭和上動觸(chu)頭的接觸(chu)可(ke)靠。

（3）熔絲的挑(tiao)選有必要符合規定，不(bu)得運(yun)用(yong)鋁絲代替，制止(zhi)運(yun)用(yong)將熔管(guan)同上靜觸頭作綁縛運(yun)用(yong)。
