(1)帶負荷合隔離開關(guān)時，即使發(fā)現(xiàn)合錯，也不準將隔離開關(guān)再拉開。因為帶負荷拉隔離開關(guān)，將造成三相弧光短路事故。 (2)帶負荷錯拉隔離開關(guān)時，杭州ETAON 隔離開關(guān)P1-25/EA/SVB/N，在刀片剛離開固定觸頭時，便發(fā)生電弧，這時應(yīng)立即合上，可以消除電弧，杭州ETAON

(6)隔離開關(guān)的結(jié)構(gòu)應(yīng)簡單，動作要可靠，有一定的機械強度；金屬制件應(yīng)能耐受氧化而不腐蝕；在冰凍的環(huán)境里能可靠地分、合閘。 (7)帶有接地開關(guān)的隔離開關(guān)，必須裝設(shè)連鎖機構(gòu)，以保證停電時先斷開隔離開關(guān), 后閉合接地開關(guān)，送電時先斷開接地開關(guān)后閉合隔離開關(guān)的操作順序。 (8)通過輔助觸點，隔離開關(guān)與斷路器之間應(yīng)有電氣閉鎖，以防帶負荷誤拉、合隔離開關(guān)。 (9)對于用在氣候寒冷地區(qū)的戶外型隔離開關(guān)應(yīng)具有設(shè)計要求的破冰能力，在冰凍的環(huán)境里應(yīng)能可靠地分合閘。 (10)對于一般戶外非GIS或HGIS用隔離開關(guān)，其外絕緣爬電距離應(yīng)滿足安裝地點的污穢等級要求，同時應(yīng)根據(jù)設(shè)計要求留有一定裕度。</p><p style="text-indent:25px">【浩蘊自動化】隔離開關(guān)的用途如下： 1.隔離電源。用隔離開關(guān)將需要檢修的開關(guān)柜、配電箱等電氣設(shè)備與帶電的電網(wǎng)可靠地隔離，以保證檢修工作人員的安全。 2.倒母線操作。在開關(guān)柜中使用雙母線制的電路中，利用隔離開關(guān)將電氣設(shè)備或供電線路從一組母線切換至另一組母線上去，即稱倒閘操作。 3.用以接通和切斷小電流的電路。利用隔離開關(guān)可以進行哪些操作： 1.分、合電壓互感器和避雷器及系統(tǒng)無接地的消弧線圈。 2.分、合空載母線及連接于母線上的設(shè)備。 3.分、合電容電流不超過5A的空載線路，線路有接地時除外。 4.分、合勵磁電流不超過2A的空載變壓器。 5.分、合10KV以下，15A以內(nèi)的負荷電流以及10KV以下、70A以內(nèi)的環(huán)流。其實，隔離開關(guān)并不是只用來切斷或接通電源那么簡單，還可以用來做很多事情，通過以上錦泰恒的介紹，我想大家應(yīng)該明白為什么在眾多的開關(guān)柜、配電柜、配電箱等電氣設(shè)備中隔離開光使用量會**多了吧。杭州哪里買得到伊頓穆勒隔離開關(guān)?</p><div

(1)應(yīng)先檢查相應(yīng)回路的斷路器、相應(yīng)的接地開關(guān)確已拉開并分閘到位，確認送電范圍接地線已拆除。 (2)隔離開關(guān)電動操作電壓應(yīng)在額定電壓的 85%-110%。 (3)手動合隔離開關(guān)迅速、果斷、但合閘終了時不可用力過猛。合閘后應(yīng)檢查動、靜觸頭是否合閘到位，接觸是否良好。 (4)手動分隔離開關(guān)，開始時應(yīng)慢而謹慎，當動觸頭剛離開觸頭時應(yīng)迅速，拉開后檢查動、靜觸頭斷開情況。 (5)隔離開關(guān)在操作過程中，如有卡滯、動觸頭不能插入靜觸頭、合閘不到位等現(xiàn)象時，應(yīng)停止操作，待缺點消除后在繼續(xù)進行。隔離開關(guān)有什么優(yōu)點？可靠么？杭州ETAON
