斷路器在分斷大的短路電流時，其動、靜觸頭分開時產(chǎn)生電弧，有一部分電弧或電離氣體從斷路器電源端噴弧口噴出，電弧本身就是一種巨大的電流，很容易導致裸露的導電體之間和裸露帶電體與"地"(成套設備的金屬外殼是接地的)的相間短路和接地短路事故。為確保安全，LZM塑殼斷路器LZMC1-A25+NZM1-XSV，用戶應根據(jù)制造廠的產(chǎn)品樣本或使用說明書提供的數(shù)據(jù)留一定距離。如配電箱，LZM塑殼斷路器LZMC1-A25+NZM1-XSV，LZM塑殼斷路器LZMC1-A25+NZM1-XSV、柜的高度距離不夠，可選用飛弧距離小或零飛弧的產(chǎn)品，以保證用電安全。

<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、外部轉動操作手柄等附件。 </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為單斷點轉換觸頭，225及以上為橋式觸頭結構，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 /> NZM塑殼斷路器NZMN1-4-A100什么是A類斷路器？什么是B類？</p><div

低壓斷路器的主觸點是靠手動操作或電動合閘的。主觸點閉合后，自由脫扣機構將主觸點鎖在合閘位置上。過電流脫扣器的線圈和熱脫扣器的熱元件與主電路串聯(lián)，欠電壓脫扣器的線圈和電源并聯(lián)。 </p> <p> 當電路發(fā)生短路或嚴重過載時，過電流脫扣器的銜鐵吸合，使自由脫扣機構動作，主觸點斷開主電路。 </p> <p> 當電路過載時，熱脫扣器的熱元件發(fā)熱使雙金屬片上彎曲，推動自由脫扣機構動作，主觸點斷開主電路。 </p> <p> 當電路欠電壓時，欠電壓脫扣器的銜鐵釋放，也使自由脫扣機構動作，主觸點斷開主電路。 </p> <p> 當按下分勵脫扣按鈕時，分勵脫扣器銜鐵吸合，使自由脫扣機構動作，主觸點斷開主電路。 </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。
