分斷能力，是人在種種情況下，作出判斷的基本能力。分段開關和聯絡開關的區(qū)別一、聯絡開關顧名思義就是起聯絡作用的。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絡柜里面。聯絡柜的上，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，伊頓穆勒

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。

<strong>塑殼斷路器</strong>各種分斷能力關系（六） </p> <p> 無論A類或B類斷路器，它們的運行短路分斷能力絕大多數是小于它的極限短路分斷能力Icu的。A類：DZ20系列Ics＝50%～77%Icu，CM1系列Ics＝58%～72%Icu，TM30系列Ics＝50%～75%Icu，(個別產品Ics＝Icu)。B類：DW15系列Ics＝60%左右的Icu，(個別的如630AIcs＝Icu，但短路分斷能力*400V時30kA)，DW45系列Ics＝62.5%～80%Icu。 </p> <p> 不管是A類或B類斷路器，只要它的Ics符合IEC947_2(或GB14048.2)標準規(guī)定的Icu百分比值都是合格產品。 </p> <p> 應提到的是，所有斷路器的短路分斷能力(無論是Icu還是Ics)都是周期分量有效值。在短路試驗中的“C0”的C(close接通)的電流是峰值電流Ich。在試驗站進行短路分斷試驗時，電壓、短路電流(有效值)和功率因數(cos)已調整好，它的接通電流也就被確定了。接通電流試驗(“C”試驗)，是以峰值電流來考核觸頭和其他導電體承受的電動斥力和熱穩(wěn)定性的能力，有什么樣的有效值電流(分斷電流)，在其相應的功率因數下，便有什么樣的峰值電流，使用者毋須去考慮峰值電流這個參數。

為了滿足不同用戶需要，現在國內許多斷路器生產廠家，對于同一殼架等級額定電流的短路分斷能力分為不同級別，例如常熟開關廠CM1-100分為C基本型(25～35kA)、L標準型(35～50kA)、M較**斷型(50～75kA)、H**斷型(85～100kA)。用戶在選用時，要符合斷路器的極限短路分斷能力，線路預期短路電流就能滿足要求，不必人為地加上保險系數，以免造成浪費。 </p> <p> 額定運行短路分斷能力的值可為額定極限短路分斷能力的25％、50％、75％、100％，大多數斷路器是50％～75％，極個別的有100％(Ics＝Icu)，如法國施耐德的梅蘭日蘭公司的NS產品。 </p> <p> <br /> </p> <p> <br /> 斷路器中板前式接線方式的介紹。</p><div style="width:100%;text-align: center;"><img

</p> <p> <br /> </p> <p> <br /> </p> <p> 空氣斷路器的主要附件 </p> <p> 空氣斷路器的內部附件（二） </p> <p> 報警觸頭：用于斷路器事故的報警觸頭，且此觸頭只有當斷路器脫扣分斷后才動作，主要用于斷路器的負載出現過載短路或欠電壓等故障時而自由脫扣，報警觸頭從原來的常開位置轉換成閉合位置，接通輔助線路中的指示燈或電鈴、蜂鳴器等，顯示或提醒斷路器的故障脫扣狀態(tài)。由于斷路器發(fā)生因負載故障而自由脫扣的機率不太多，因而報警觸頭的壽命是斷路器壽命的1/10。報警觸頭的工作電流一般不會超過1A。 </p>

⑻限流分斷能力 </p> <p> 限流分斷能力是指電路發(fā)生短路時，斷路器跳閘時限制故障電流的能力。電路發(fā)生短路時，斷路器觸頭快速打開，產生電弧，相當于在線路中串入1個迅速增加的電弧電阻，從而限制了故障電流的增加，降低了短路電流的電磁效應、電動效應和熱效應對斷路器和用電設備的不良影響，延長斷路器的使用壽命。斷路器斷開時間越短，限流效果就越好，Ics就越接近Icu。 </p> <p> ⑼微型斷路器的脫扣特性 </p> <p> 斷路器脫扣特性分為A、B、C、D、K等幾種，各自的含義如下： </p> <p> A型脫扣特性：脫扣電流為（2～3）In，適用于保護半導體電子線路，帶小功率電源變壓器的測量線路，或線路長且短路電流小的系統(tǒng)； </p> <p> B型脫扣特性：脫扣電流為（3～5）In，適用于住戶配電系統(tǒng)，家用電器的保護和人身安全保護； </p> <p> C型脫扣特性：脫扣電流為（5～10）In，適用于保護配電線路以及具有較高接通電流的照明線路和電動機回路； </p> <p> D型脫扣特性：脫扣電流為（10～20）In，適用于保護具有很高沖擊電流的設備，如變壓器、電磁閥等； </p> <p> K型脫扣特性：具備1.2倍熱脫扣動作電流和8～14倍磁脫扣動作范圍，適用于保護電動機線路設備，有較高的抗沖擊電流能力。伊頓穆勒
