DZ20-100和DZ20-225兩種殼架等級中都有100A額定電流，但斷路器體積外形和分斷能力不相同，因此在選用時要把型號填寫完整即具體的殼架等級額定電流內的斷路器額定電流。額定電流分級是按(1.25)優(yōu)先系數來選擇的：一方面是符合和滿足比較大線路和電器元件額定電流的需要；另一方面是為了標準化，以取得比較好的使用導線及加工的效益。 </p> <p> 因此它所規(guī)定的級別是：3(6)、8、10、12.5、16，20、25、32、40、50、63、80，100、125、160、200、250、315，伊頓穆勒 NZM塑殼斷路器NZMN3-VE400-S、400A等。由于此規(guī)定，當線路計算負載為90A時，伊頓穆勒 NZM塑殼斷路器NZMN3-VE400-S，則只能選100A規(guī)格，伊頓穆勒 NZM塑殼斷路器NZMN3-VE400-S，因此在一定程度上影響它的保護性能。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 自動化技術之塑殼斷路器型號。伊頓穆勒 NZM塑殼斷路器NZMN3-VE400-S</p><div style="width:100%;text-align: center;"><img style="max-width:

</p> <p> <strong>塑殼斷路器</strong>的作用 </p> <p> 1.正常倩況下接通和斷開高壓電路中的空載及負荷電流; </p> <p> 2.在系統(tǒng)發(fā)生故障時能與保護裝置和自動裝置相配合迅速切斷故障電流防止事故擴大從而保證系統(tǒng)安全運行。 </p> <p> 一般情況下塑殼斷路器本身不存在潤滑方面的問題，需要潤滑的常常是它的操動機構。熱繼電器的作用是電動機過負荷時自動切斷電源，熱繼電器的構造是兩片膨脹系數不同的金屬片構成，電流過大時膨脹系數大的先膨脹，起到切斷電源的作用。熱繼電器動作后有人工復位和自動復位。熔斷器作用：當電路發(fā)生故障或異常時，伴隨著電流不斷升高，并且升高的電流有可能損壞電路中的某些重要器件或貴重器件，也有可能燒毀電路甚至造成火災。

</p> <p> 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。由于結構非常緊湊，塑殼斷路器基本無法檢修。其多采用手動操作，大容量可選擇電動分合。由于電子式過電流脫扣器的應用，塑殼斷路器也可分為A類和B類兩種，B類具有良好的三段保護特性，但由于價格因素，采用熱磁式脫扣器的A類產品的市場占有率更高。塑殼斷路器是將觸頭、滅弧室、脫扣器和操作機構等都裝在一個塑料外殼內，一般不考慮維修，適用于作支路的保護開關，過電流脫扣器有熱磁式和電子式兩種，一般熱磁式塑殼斷路器為非選擇性斷路器，*有過載長延時及短路瞬時兩種保護方式，電子式塑殼斷路器有過載長延時、短路短延時、短路瞬時和接地故障四種保護功能。部分電子式塑殼斷路器新推出的產品還帶有區(qū)域選擇性連鎖功能。大多數塑殼斷路器為手動操作，也有部分帶電動機操作機構。

電動操作機構：是用于遠距離自動分閘和合閘斷路器的一種附件，電動操作機構有電動機操作機構和電磁鐵操作機構兩種，電動機操作機構為塑殼式斷路器殼架等級額定電流400A及以上斷路器，電磁鐵操作機構適用于塑殼斷呼器殼架等級額定電流225A及以下斷路器，無論是電磁鐵或電動機，它們的吸合和轉動方向都是相同，*由電動操作機構內部的凸輪的位置來達到合、分，斷路器在用電動機構操作時，在額定控制電壓的85%-110%之間的任一電壓下，應能保證斷路器可靠閉合。

塑殼斷路器廣泛應用于工農業(yè)、交通、礦山、民用建筑和**等部門，對電力的傳輸和分配、電路的控制與保護起很大作用，是一種使用量大，面廣的產品。由于使用者對塑殼斷路器的特性和技術要求了解不深或不***，有些概念容易互相混淆，在實際應用中就經常出現(xiàn)一些偏失和誤解。本文對用戶在選擇和使用塑殼斷路器時容易出現(xiàn)的問題做一介紹，以幫助用戶合理選擇使用塑殼斷路器。 </p> <p> 斷路器殼架等級額定電流是指基本尺寸相同的框架和塑料外殼中能裝的比較大脫扣器的額定電流。 </p> <p> <br /> </p> <p> <br /> 空氣斷路器的主要作用是什么？伊頓穆勒 ETAON NZM塑殼斷路器NZMN2-S125</p><p style="text-indent:25px">高海拔環(huán)境下塑殼斷路器熱脫和穩(wěn)定性研究。伊頓穆勒

斷路器在分斷大的短路電流時，其動、靜觸頭分開時產生電弧，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，用戶應根據制造廠的產品樣本或使用說明書提供的數據留一定距離。如配電箱、柜的高度距離不夠，可選用飛弧距離小或零飛弧的產品，以保證用電安全。 </p> <p>
