額定絕緣電壓是設計斷路器的電壓值，電氣間隙和爬電距離應參照此值而定。有些斷路器沒有明確規(guī)定額定絕緣電壓，應將額定工作電壓中比較大值視作額定絕緣電壓，在任何情況下，比較大額定工作電壓不超過額定絕緣電壓，斷路器的額定絕緣電壓與工頻試驗電壓見表1。額定工作電壓是指通斷能力以及使用類別相關的電壓值，塑殼斷路器的額定工作電壓多為50Hz、380V，但也有50Hz、600V，額定工作電壓380V、50Hz的塑殼斷路器，***不允許用到660V或1140V的電源電壓上。

聯(lián)鎖裝置有機械聯(lián)鎖和電氣聯(lián)鎖兩種類型。工作原理是： </p> <p> （1）機械聯(lián)鎖裝置一般使用鋼絲繩或者杠桿機構，以機械位置的變動（也可采用多功能程序鎖）來保證在斷路器切斷電源以前，隔離開關的操作把手不能動作。 </p> <p> （2）電氣聯(lián)鎖裝置電氣聯(lián)鎖一般有兩種聯(lián)鎖方式，一種是通過操作機構上的聯(lián)動輔助接點（常開或常閉）去控制隔離開關的把手。當斷路器未斷開時，隔離開關操作把手不能動作。 </p> <p> 另一種電氣聯(lián)鎖是利用距離開關操作機構上的聯(lián)動輔助接點（常開或常閉）去控制斷路器。當拉動隔離開關的把手時，聯(lián)動輔助接點（常開或常閉）使斷路器動作以切斷電路，從而可防止帶負荷拉動距離開關的事故。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <strong>塑殼斷路器</strong>的接線方式（一） </p> <p> 斷路器的接線方式有板前、板后、插入式、抽屜式，用戶如無特殊要求，均按板前供貨，板前接線是常見的接線方式。 </p> <p> 1、板后接線方式：板后接線比較大特點是可以在更換或維修斷路器，不必重新接線，只須將前級電源斷開。由于該結構特殊，產品出廠時已按設計要求配置了**安裝板和安裝螺釘及接線螺釘，需要特別注意的是由于大容量斷路器接觸的可靠性將直接影響斷路器的正常使用，因此安裝時必須引起重視，嚴格按制造廠要求進行安裝。 </p> <p> <br /> </p> <p> <br />

4)欠電壓脫扣器用作線路及電源設備的久電壓保護，使用時欠電壓脫扣器線圈接在斷路器電源側，欠電壓脫扣器通電后斷路器才能合閘，否則斷路器合不上閘。使用者應確認線路與欠電壓脫扣器的工作電壓是否一致。欠電壓的工作范圍為(70％～35％)Un。欠電壓脫扣器也有多種額定工作電壓和不同電源頻率，可供不同場合，不同電源時選用。 </p> <p> 5)電動操作機構用于斷路器的自動控制和遠距離的閉合和斷開之用。有電動操作機構和電磁操作機構兩種：電動操作機構由電動機驅動，一般適用于殼架等級額定電流400A及以上斷路器，電磁鐵操作機構適用于殼架等級額定電流225A及以下斷路器。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br />

<strong>塑殼斷路器</strong>各種分斷能力關系（七） </p> <p> 人的分斷能力 </p> <p> 分斷能力，是人在種種情況下，作出判斷的基本能力。分段開關和聯(lián)絡開關的區(qū)別一、聯(lián)絡開關顧名思義就是起聯(lián)絡作用的。主要用在兩個電源，兩臺變壓器的配電系統(tǒng)中，兩臺變壓器的主控柜分別出線到聯(lián)絡柜里面。聯(lián)絡柜的上，下口分別接兩臺主控的出線，即一個采用上口進線，一個采用下口進線，一般兩臺柜子要形成互鎖，不能同時使用，平時只開其中一臺，另外一臺備用。二、分段開關線路自動分段開關，簡稱分段開關，是配電網(wǎng)提高可靠性和自動化程度的一個重要設備，***的應用于配電線路的分支線或區(qū)段線路上用來隔離長久故障；它不具備開斷短路故障電流的能力，不能單獨作為主保護開關設備，只能與電源側前級開關設備想配合，在無電流的情況下自動分閘。 </p> <p> 它們既有相同點，也有各自的特點。 </p> <p> <br /> </p> <p> <br /> 伊頓穆勒塑殼斷路器NZMB1-4-A20</p></p><br /><p>文章來源地址: http://www.cdcfah.com/cp/3096698.html</p></div></div></div></div></div><div id="88wycwi"
