背景技術:
:
避雷(lei)器就是在線(xian)(xian)(xian)(xian)路上(shang)或設(she)備上(shang)人(ren)為制(zhi)造絕(jue)(jue)緣(yuan)(yuan)薄(bo)弱點即間隙的(de)裝(zhuang)置,間隙的(de)擊(ji)穿電(dian)(dian)壓比線(xian)(xian)(xian)(xian)路或設(she)備的(de)雷(lei)電(dian)(dian)沖擊(ji)絕(jue)(jue)緣(yuan)(yuan)水平低,在正常運行電(dian)(dian)壓下間隙處于絕(jue)(jue)緣(yuan)(yuan)隔離狀(zhuang)態,在過(guo)電(dian)(dian)壓下間隙被擊(ji)穿接地,放電(dian)(dian)、降壓起到保護(hu)線(xian)(xian)(xian)(xian)路或設(she)備絕(jue)(jue)緣(yuan)(yuan)的(de)作用(yong)(yong)。金屬(shu)氧(yang)化鋅避雷(lei)器因(yin)其性能(neng)優良被廣泛應用(yong)(yong)于10kV配電(dian)(dian)線(xian)(xian)(xian)(xian)路中,用(yong)(yong)以限制(zhi)過(guo)電(dian)(dian)壓,保護(hu)配電(dian)(dian)線(xian)(xian)(xian)(xian)路或設(she)備。
在實(shi)際(ji)應用(yong)中,由于運行年限長、運行環境惡劣(lie),特別是在雷(lei)電活動較為活躍的地區,一(yi)些避雷(lei)器經常會發生老(lao)化、故障等情況,嚴重影響(xiang)配電線路和設備的安全運行,需(xu)要對這些避雷(lei)器進行更換。
停電(dian)更換避雷器(qi)需要(yao)中斷某(mou)一區域的(de)電(dian)力供(gong)應,影響(xiang)大量用戶的(de)正常生(sheng)產和(he)生(sheng)活,降低(di)供(gong)電(dian)可靠(kao)性,這(zhe)種作業方(fang)式已(yi)經越(yue)來越(yue)不(bu)適應供(gong)電(dian)公司優質(zhi)服務的(de)要(yao)求(qiu)和(he)當(dang)今電(dian)網(wang)的(de)發展(zhan)趨勢(shi),非(fei)必須時一般(ban)不(bu)采用。
目前帶電(dian)更換避(bi)雷器工作(zuo)(zuo)(zuo)是(shi)通過(guo)中(zhong)間電(dian)位(wei)(wei)作(zuo)(zuo)(zuo)業(ye)(ye)(ye)法進行,即作(zuo)(zuo)(zuo)業(ye)(ye)(ye)人(ren)(ren)員(yuan)戴絕(jue)緣安全(quan)帽,穿全(quan)套絕(jue)緣服,操作(zuo)(zuo)(zuo)絕(jue)緣斗臂(bei)車絕(jue)緣斗接(jie)近作(zuo)(zuo)(zuo)業(ye)(ye)(ye)位(wei)(wei)置(zhi)(zhi)進行檢修作(zuo)(zuo)(zuo)業(ye)(ye)(ye)。中(zhong)間電(dian)位(wei)(wei)作(zuo)(zuo)(zuo)業(ye)(ye)(ye)法更換避(bi)雷器存在(zai)四處(chu)不足(zu):一是(shi)受地(di)形條件限(xian)制,電(dian)桿若處(chu)在(zai)山地(di)、果園等復(fu)雜(za)地(di)形時,絕(jue)緣斗臂(bei)車無法到(dao)達作(zuo)(zuo)(zuo)業(ye)(ye)(ye)位(wei)(wei)置(zhi)(zhi),無法開展作(zuo)(zuo)(zuo)業(ye)(ye)(ye);二是(shi)企業(ye)(ye)(ye)成本高,需要出動作(zuo)(zuo)(zuo)業(ye)(ye)(ye)人(ren)(ren)員(yuan)數量多,出動大型車輛絕(jue)緣斗臂(bei)車;三是(shi)作(zuo)(zuo)(zuo)業(ye)(ye)(ye)人(ren)(ren)員(yuan)存在(zai)安全(quan)風險,配電(dian)線路緊(jin)湊,電(dian)氣設備布置(zhi)(zhi)密集,作(zuo)(zuo)(zuo)業(ye)(ye)(ye)范圍窄小,作(zuo)(zuo)(zuo)業(ye)(ye)(ye)人(ren)(ren)員(yuan)靠近帶電(dian)體作(zuo)(zuo)(zuo)業(ye)(ye)(ye),容(rong)易發生(sheng)相地(di)短路或相間短路危險;四是(shi)工作(zuo)(zuo)(zuo)效率低,作(zuo)(zuo)(zuo)業(ye)(ye)(ye)步驟(zou)多,程序(xu)復(fu)雜(za),工作(zuo)(zuo)(zuo)耗時長。
地(di)電(dian)位作(zuo)業法(fa)即作(zuo)業人員通過腳扣攀(pan)登桿(gan)(gan)塔至適當位置(zhi),通過絕緣操作(zuo)桿(gan)(gan)進(jin)行(xing)帶電(dian)檢修作(zuo)業,應用(yong)此方法(fa)更換避(bi)雷器可以克(ke)服中(zhong)間電(dian)位法(fa)更換避(bi)雷器時存在(zai)的不足,但是目前無(wu)(wu)地(di)電(dian)位法(fa)更換避(bi)雷器的專用(yong)工(gong)具,導(dao)致地(di)電(dian)位法(fa)更換避(bi)雷器工(gong)作(zuo)無(wu)(wu)法(fa)開(kai)展(zhan)。

1. 結構簡單、安(an)(an)裝(zhuang)(zhuang)方便。易形套(tao)筒(tong)(tong)的絕緣下底座左(zuo)側(ce)(ce)的前(qian)后兩端各連(lian)接一個橫(heng)擔(dan)卡(ka)槽(cao),右側(ce)(ce)有一操作(zuo)桿(gan)卡(ka)環(huan),頂部(bu)左(zuo)側(ce)(ce)安(an)(an)裝(zhuang)(zhuang)有可拆(chai)卸套(tao)筒(tong)(tong),將(jiang)絕緣操作(zuo)桿(gan)穿過操作(zuo)桿(gan)卡(ka)環(huan)并連(lian)接到(dao)操作(zuo)桿(gan)套(tao)筒(tong)(tong)連(lian)接頭,用操作(zuo)桿(gan)將(jiang)工具挑(tiao)至避(bi)雷(lei)(lei)(lei)器(qi)橫(heng)擔(dan)處,避(bi)雷(lei)(lei)(lei)器(qi)置于兩個橫(heng)擔(dan)卡(ka)槽(cao)中間(jian),橫(heng)擔(dan)卡(ka)槽(cao)卡(ka)到(dao)避(bi)雷(lei)(lei)(lei)器(qi)橫(heng)擔(dan)上(shang),同時(shi)將(jiang)套(tao)筒(tong)(tong)套(tao)到(dao)避(bi)雷(lei)(lei)(lei)器(qi)上(shang)樁頭螺(luo)母上(shang)即(ji)完成安(an)(an)裝(zhuang)(zhuang)。避(bi)雷(lei)(lei)(lei)器(qi)抓手(shou)(shou)為(wei)夾(jia)取避(bi)雷(lei)(lei)(lei)器(qi)專(zhuan)用工具,通過操作(zuo)桿(gan)抓手(shou)(shou)連(lian)接頭把避(bi)雷(lei)(lei)(lei)器(qi)抓手(shou)(shou)和操作(zuo)桿(gan)緊密(mi)連(lian)接,旋轉操作(zuo)桿(gan)帶動長絲桿(gan)旋轉控制錐形頂頭伸縮(suo),實現對(dui)抓手(shou)(shou)開(kai)口大小進行控制,從(cong)而抓緊和松開(kai)避(bi)雷(lei)(lei)(lei)器(qi)。
2. 安全可(ke)靠。本發明主(zhu)要構件(jian)全部由環(huan)氧樹脂絕緣材料(liao)制作(zuo),部分金(jin)屬(shu)構件(jian)表面(mian)也由環(huan)氧樹脂絕緣罩(zhao)覆蓋(gai),絕緣性能好,可(ke)以防止工具在(zai)使(shi)用過程中(zhong),由于操(cao)作(zuo)幅度(du)過大使(shi)工具同時接觸帶電體和接地體,發生相地和相間短路危險;同時,作(zuo)業人(ren)員通過絕緣操(cao)作(zuo)桿進(jin)行作(zuo)業,時刻處在(zai)安全距離以外(wai),作(zuo)業人(ren)員的安全得到可(ke)靠保障。
3. 適(shi)用(yong)范(fan)圍廣。本發明的使用(yong)不(bu)受地形條件的限制,可以
實現全(quan)地形范圍更換避雷器(qi)的工(gong)作。
4. 提高帶電作業(ye)效率。使(shi)用(yong)本發明進行(xing)(xing)地電位(wei)法更換避雷(lei)器,作業(ye)人員通過絕緣操(cao)作桿進行(xing)(xing)作業(ye),減少了許多不必要的絕緣遮(zhe)蔽步驟(zou),優化了作業(ye)流程(cheng),減少了作業(ye)時間(jian),降低了作業(ye)人員勞動強度(du),提高了帶電作業(ye)效率。
5. 降低企業(ye)成本。中間電(dian)位法進行(xing)更(geng)換(huan)(huan)避雷器工(gong)作(zuo)需(xu)要5人工(gong)作(zuo)小組,同(tong)時需(xu)要出動(dong)絕緣斗(dou)臂車;采用本發明地電(dian)位法更(geng)換(huan)(huan)避雷器只需(xu)要4人工(gong)作(zuo)小組,無需(xu)出動(dong)大(da)型車輛(liang)。
