（1）高壓(ya)電瓷(ci)表面的(de)清洗(xi)：

電力(li)設(she)施(shi)(設(she)備(bei))的清(qing)洗(xi)，主要(yao)是對裸(luo)露在(zai)戶外的部件表面進(jin)行清(qing)洗(xi)(防護)，其方法(fa)是定期進(jin)行清(qing)洗(xi)和(he)涂有機硅涂料。其目的是清(qing)除瓷表面上(shang)的污穢(hui)。

以前(qian)使用(yong)(yong)的(de)(de)(de)水(shui)(shui)(shui)(shui)沖(chong)(chong)(chong)(chong)洗(xi)(xi)(xi)(xi)(xi)絕緣子表面污穢方法進行帶(dai)(dai)(dai)電(dian)(dian)水(shui)(shui)(shui)(shui)沖(chong)(chong)(chong)(chong)洗(xi)(xi)(xi)(xi)(xi)設(she)備，由于種種原因(yin)，不(bu)(bu)安全的(de)(de)(de)現象時有(you)(you)發(fa)生，發(fa)生了一(yi)(yi)些人身和(he)設(she)備閃(shan)絡(luo)(luo)事故。原因(yin)是帶(dai)(dai)(dai)電(dian)(dian)水(shui)(shui)(shui)(shui)沖(chong)(chong)(chong)(chong)洗(xi)(xi)(xi)(xi)(xi)要(yao)(yao)求條件(jian)(jian)比較高(gao)，稍有(you)(you)疏忽，就有(you)(you)發(fa)生不(bu)(bu)安全現象的(de)(de)(de)可能。部頒安規(gui)中電(dian)(dian)氣設(she)備帶(dai)(dai)(dai)電(dian)(dian)水(shui)(shui)(shui)(shui)沖(chong)(chong)(chong)(chong)洗(xi)(xi)(xi)(xi)(xi)導(dao)則規(gui)定(ding)的(de)(de)(de)沖(chong)(chong)(chong)(chong)洗(xi)(xi)(xi)(xi)(xi)條件(jian)(jian)很(hen)嚴(yan)。其(qi)(qi)(qi)一(yi)(yi)，帶(dai)(dai)(dai)電(dian)(dian)水(shui)(shui)(shui)(shui)沖(chong)(chong)(chong)(chong)洗(xi)(xi)(xi)(xi)(xi)的(de)(de)(de)水(shui)(shui)(shui)(shui)阻率要(yao)(yao)求一(yi)(yi)般不(bu)(bu)低于1500Ω·cm；其(qi)(qi)(qi)二，要(yao)(yao)了解進行水(shui)(shui)(shui)(shui)沖(chong)(chong)(chong)(chong)洗(xi)(xi)(xi)(xi)(xi)的(de)(de)(de)帶(dai)(dai)(dai)電(dian)(dian)設(she)備污穢的(de)(de)(de)絕緣子的(de)(de)(de)鹽密值(zhi)，其(qi)(qi)(qi)鹽密值(zhi)不(bu)(bu)能大于導(dao)則中規(gui)定(ding)的(de)(de)(de)值(zhi)。這項(xiang)工作很(hen)麻煩。其(qi)(qi)(qi)三，帶(dai)(dai)(dai)電(dian)(dian)水(shui)(shui)(shui)(shui)沖(chong)(chong)(chong)(chong)洗(xi)(xi)(xi)(xi)(xi)前(qian)要(yao)(yao)確(que)知設(she)備絕緣良(liang)好，有(you)(you)零值(zhi)或低絕緣子及(ji)瓷質有(you)(you)裂紋時一(yi)(yi)般不(bu)(bu)可沖(chong)(chong)(chong)(chong)洗(xi)(xi)(xi)(xi)(xi)，作好這項(xiang)目也有(you)(you)一(yi)(yi)定(ding)的(de)(de)(de)難度；其(qi)(qi)(qi)四，水(shui)(shui)(shui)(shui)沖(chong)(chong)(chong)(chong)洗(xi)(xi)(xi)(xi)(xi)的(de)(de)(de)方法也有(you)(you)嚴(yan)格要(yao)(yao)求，注意風向和(he)沖(chong)(chong)(chong)(chong)洗(xi)(xi)(xi)(xi)(xi)角度，防止濺閃(shan)(即影響鄰近(jin)設(she)備發(fa)生閃(shan)絡(luo)(luo))；其(qi)(qi)(qi)五(wu)，對充油套管(guan)不(bu)(bu)能采用(yong)(yong)水(shui)(shui)(shui)(shui)沖(chong)(chong)(chong)(chong)洗(xi)(xi)(xi)(xi)(xi)。其(qi)(qi)(qi)六、水(shui)(shui)(shui)(shui)本(ben)身沒有(you)(you)除油污能力。總之，帶(dai)(dai)(dai)電(dian)(dian)水(shui)(shui)(shui)(shui)沖(chong)(chong)(chong)(chong)洗(xi)(xi)(xi)(xi)(xi)雖(sui)然可收到一(yi)(yi)定(ding)的(de)(de)(de)效果，但是除了要(yao)(yao)求保持安全距離及(ji)水(shui)(shui)(shui)(shui)柱長度等前(qian)提條件(jian)(jian)外，還要(yao)(yao)滿足上述的(de)(de)(de)幾個條件(jian)(jian)。條件(jian)(jian)如此苛刻，所以帶(dai)(dai)(dai)電(dian)(dian)水(shui)(shui)(shui)(shui)沖(chong)(chong)(chong)(chong)洗(xi)(xi)(xi)(xi)(xi)推廣應用(yong)(yong)受到一(yi)(yi)定(ding)局限。

化學清洗的安全性和效果都遠比水沖洗好得多，特別是對進入跨世紀的超高壓大電網，更需要定期對電力設備電瓷表面進行清洗，以保持高壓電瓷表面的清潔，防止污閃事故的發生。廣州海日帶電清洗方法采用帶電清掃和化學清洗加絕緣養護三部分組成，也稱“三位一體”清洗法。

（2）開關柜和二次線端子(zi)排的清(qing)洗：

開關柜和二(er)次線端子排雖(sui)然是(shi)裝在(zai)室內，運行(xing)(xing)時(shi)間長了也有一個污穢(hui)(hui)清(qing)洗(xi)(xi)的(de)(de)(de)問題，這(zhe)(zhe)些設備(bei)是(shi)不(bu)能(neng)停電(dian)的(de)(de)(de)，只能(neng)在(zai)運行(xing)(xing)中對(dui)其清(qing)洗(xi)(xi)。用(yong)帶電(dian)清(qing)洗(xi)(xi)劑來清(qing)洗(xi)(xi)這(zhe)(zhe)些設備(bei)污穢(hui)(hui)效(xiao)果很好，而(er)(er)且也安全(quan)可靠。通過清(qing)洗(xi)(xi)劑的(de)(de)(de)沖洗(xi)(xi)，表面(mian)污穢(hui)(hui)將一掃而(er)(er)光，使接(jie)(jie)點接(jie)(jie)觸良(liang)好了，而(er)(er)且通過這(zhe)(zhe)種化學清(qing)洗(xi)(xi)還會發現接(jie)(jie)觸不(bu)良(liang)發熱的(de)(de)(de)缺陷。清(qing)洗(xi)(xi)劑的(de)(de)(de)燃點在(zai)500℃以下，不(bu)會燃燒(shao)起火，所(suo)以完全(quan)可以在(zai)載流的(de)(de)(de)設備(bei)接(jie)(jie)頭進行(xing)(xing)清(qing)洗(xi)(xi)。

（3） 注油設備及套(tao)管的清洗：

要(yao)保(bao)護電網的(de)(de)安全運行(xing)，電力注油設備就要(yao)消除油的(de)(de)滲漏及其(qi)表(biao)面的(de)(de)油污，用帶電清(qing)洗劑去清(qing)洗并用特殊的(de)(de)粘(zhan)結劑進行(xing)堵(du)漏，就可達到清(qing)潔和防止(zhi)滲漏的(de)(de)目的(de)(de)。

開(kai)展輸變(bian)電設備(bei)瓷表面污(wu)穢清掃(sao)工作是恢復設備(bei)原有絕緣水平(ping)、防止污(wu)閃事故發生、保證電網安全(quan)運行的有效措施。隨著電網電壓(ya)等級的提高(gao)和系統容(rong)量的增長，設備(bei)停電的機會越(yue)來(lai)越(yue)少，停電時間也越(yue)來(lai)越(yue)短。高(gao)壓(ya)輸變(bian)電設備(bei)帶電清掃(sao)作業(ye)勢在必行。

我們(men)提供的高(gao)壓電力(li)設備帶電清洗維(wei)護(hu)技術能對380V-550KV的高(gao)壓電力(li)設備在(zai)不停電的情況下，進行帶電清洗維(wei)護(hu)，徹底消除(chu)絕(jue)緣子、母排(pai)、端子箱、變壓器等表(biao)面(mian)及(ji)深(shen)層(ceng)的各(ge)種(zhong)污染(ran)物(wu)質，防范(fan)污閃、霧閃事故(gu)發(fa)生（消除(chu)事故(gu)隱患），保證電力(li)設備正(zheng)(zheng)常工作避免重大惡(e)性事故(gu)發(fa)生，提高(gao)電力(li)企業及(ji)用(yong)電企業的經濟(ji)效益，保證社會生產、生活的正(zheng)(zheng)常秩(zhi)序
