描述

5SHY3545L0020

處理故障電容器應(yīng)在斷開電容器的斷路器,拉開斷路器兩則的隔離開關(guān),并對電容器組經(jīng)放電電阻放電后進行。電容器組經(jīng)放電電阻(放電變壓器或放電電壓互感器)放電以后,由于部分殘存電荷一時放不盡,仍應(yīng)進行一次人工放電。放電時先將接地線接地端接好,再用接地棒多次對電容器放電,直至無放電火花及放電聲為止,然后將接地端固定好。由于故障電容器可能發(fā)生引線接觸不良、內(nèi)部斷線或熔絲熔斷等,因此有部分電荷可能未放盡,所以檢修人員在接觸故障電容器之前,還應(yīng)戴上絕緣手套,先用短路線將故障電容器兩極短接,然后方動手拆卸和更換。對于雙星形接線的電容器組的中性線上,以及多個電容器的串接線上,還應(yīng)單獨進行放電。
電容器在變電所各種設(shè)備中屬于可靠性比較薄弱的電器,它比同級電壓的其他設(shè)備的絕緣較為薄弱,內(nèi)部元件發(fā)熱較多,而散熱情況又欠佳,內(nèi)部故障機會較多,制造電力電容器內(nèi)部材料的可燃物成分又大,所以運行中極易著火。因此,對電力電容器的運行應(yīng)盡可能地創(chuàng)造良好的低溫和通風條件。當電容器噴油、爆炸著火時,應(yīng)立即斷開電源,并用砂子或干式滅火器滅火。此類事故多是由于系統(tǒng)內(nèi)、外過電壓,電容器內(nèi)部嚴重故障所引起的。為了防止此類事故發(fā)生,要求單臺熔斷器熔絲規(guī)格必須匹配,熔斷器熔絲熔斷后要認真查找原因,電容器組不得使用重合閘,跳閘后不得強送電,以免造成更大損壞的事故。
電容器的斷路器跳閘,而分路熔斷器熔絲未熔斷。應(yīng)對電容器放電3min后,再檢查斷路器、電流互感器、電力電纜及電容器外部等情況。若未發(fā)現(xiàn)異常,則可能是由于外部故障或母線電壓波動所致,并經(jīng)檢查正常后,可以試投,否則應(yīng)進一步對保護做全面的通電試驗。通過以上的檢查、試驗,若仍找不出原因,則應(yīng)拆開電容器組,并逐臺進行檢查試驗。但在未查明原因之前,不得試投運。
當電容器的熔斷器熔絲熔斷時,應(yīng)向值班調(diào)度員匯報,待取得同意后,再斷開電容器的斷路器。在切斷電源并對電容器放電后,先進行外部檢查,如套管的外部有無閃絡(luò)痕跡、外殼是否變形、漏油及接地裝置有無短路等,然后用絕緣搖表搖測極間及極對地的絕緣電阻值。如未發(fā)現(xiàn)故障跡象,可換好熔斷器熔絲后繼續(xù)投入運行。如經(jīng)送電后熔斷器的熔絲仍熔斷,則應(yīng)退出故障電容器,并恢復(fù)對其余部分的送電運行。

2、由位控邏輯入手,逐漸增加定時、計數(shù)等條件,把或、與、非關(guān)系理順;
3、進而練習整數(shù)運算、實數(shù)運算、類型轉(zhuǎn)換;
4、量程轉(zhuǎn)換、PID調(diào)節(jié)回路的建立及P、I、D參數(shù)的理解(最好是有個物理回路驗證,比如變頻器+電機+測速傳感器);
5、循環(huán)、順序、跳轉(zhuǎn)等程序控制(盡量避免跳轉(zhuǎn),非跳不可時也是跳的越近越好);
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機器人配件DSQC系列和Motorola MVME系列,GE 卡件 模塊 驅(qū)動器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌,由于PLC的基本框架大同小異,學會一種至于其它的學習起來也就簡單了。
