<strong>塑殼斷路器</strong>能夠在電流超過跳脫設(shè)定后自動切斷電流。塑殼指的是用塑料絕緣體來作為裝置的外殼，用來隔離導體之間以及接地金屬部分。塑殼斷路器通常含有熱磁跳脫單元，而大型號的塑殼斷路器會配備固態(tài)跳脫傳感器。其脫扣單元分為：熱磁脫扣與電子脫扣器。常用的額定電流共有以下幾種16、25、30、40、50、63、80、100、125、160、200、225、250、315、350、400、500、630A。塑殼斷路器也被稱為裝置式斷路器，所有的零件都密封于塑料外殼中，輔助觸點，欠電壓脫扣器以及分勵脫扣器等多采用模塊化。

塑殼式斷路器如何選型（四） </p> <p> 脫扣器電流整定值是指脫扣器調(diào)整到動作電流值。它是指額定電流In的倍數(shù)，是動作電流值，例如：過電流整定到電流的1.2、1.3、5、10倍，就寫成Ir＝1.2In，1.3In、5In、10In等?，F(xiàn)在一些電子脫扣器，它的過載長延時額定電流是可調(diào)的，所調(diào)整的電流，其實仍是額定電流，是可長期通過的比較大電流。 </p> <p> 額定工作電流是斷路器在裝輔助觸頭(附件)時觸點在一定工作電壓下的實際工作電流，電流為3A或6A，用于控制和保護回路。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <strong>塑殼式斷路器</strong>如何選型（八） </p> <p> 附件作為斷路器功能的派生和補充，為斷路器增加了控制手段和擴大保護功能，是斷路器不可分割的一個重要部分，主要包括輔助觸頭、報警觸頭、分勵脫扣器、欠電壓脫扣器、電動操作機構(gòu)、外部轉(zhuǎn)動操作手柄等附件。 </p> <p> 1)輔助觸頭主要用于斷路器分、合狀態(tài)顯示但無法顯示是否故障脫扣，接在斷路器的控制電路中，塑殼斷路器殼架等級額定電流100為單斷點轉(zhuǎn)換觸頭，225及以上為橋式觸頭結(jié)構(gòu)，約定發(fā)熱電流3A；殼架等級額定電流400及以上可裝兩常開、兩常閉，約定發(fā)熱電流為6A。 </p> <p> 2)報警觸頭主要用于斷路器的負載出現(xiàn)過載、短路或欠電壓等故障時而自由脫扣。報警觸頭的工作電流是：AC380V、0.3A、DC220V、0.15A，一般不會超過1A，而發(fā)熱電流可以是1～2.5A范圍。 </p> <p> <br /> </p> <p> <br /> 塑殼斷路器的工作原理是怎樣的？</p><div style="width:100%;text-align:

<p> <br /> </p> <p> <br /> </p> <p> 空氣斷路器的內(nèi)部附件（三） </p> <p> 分勵脫扣器：是一種用電壓源激勵的脫扣器，它的電壓可與主電路電壓無關(guān)。分勵脫扣器是一種遠距離操縱分閘的附件。當電源電壓等于額定控制電源電壓的70%-110%之間的任一電壓時，就能可靠分斷斷路器。分勵脫扣器是短時工作制，線圈通電時間一般不能超過1S，否則線會被燒毀。塑殼斷路器為防止線圈燒毀，在分勵脫扣線圈串聯(lián)一個微動開關(guān)，當分勵脫扣器通過銜鐵吸合，微動開關(guān)從常閉狀態(tài)轉(zhuǎn)換成常開，由于分勵脫扣器電源的控制線路被切斷，即使人為地按住按鈕，分勵線圈始終不再通電就避免了線圈燒損情況的產(chǎn)生。當斷路器再扣合閘后，微動開關(guān)重新處于常閉位置。

</p> <p> <strong>塑殼斷路器</strong>各種分斷能力關(guān)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(guān)和聯(lián)絡(luò)開關(guān)的區(qū)別一、聯(lián)絡(luò)開關(guān)顧名思義就是起聯(lián)絡(luò)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(luò)柜里面。聯(lián)絡(luò)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(guān)線路自動分段開關(guān)，簡稱分段開關(guān)，是配電網(wǎng)提高可靠性和自動化程度的一個重要設(shè)備，***的應(yīng)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(guān)設(shè)備，只能與電源側(cè)前級開關(guān)設(shè)備想配合，在無電流的情況下自動分閘。
