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(shù)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(chǎn)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(chǎn)品，NZM塑殼斷路器NZMC3-S320-E。 </p> <p> 應(yīng)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，NZM塑殼斷路器NZMC3-S320-E，NZM塑殼斷路器NZMC3-S320-E，電壓、短路電流(有效值)和功率因數(shù)(cos)已調(diào)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(dǎo)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(yīng)的功率因數(shù)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(shù)。

運行短路分斷能力的試驗條件極為苛刻(一次分斷、二次通斷)，由于試后它還要繼續(xù)承載額定電流(其次數(shù)為壽命數(shù)的5%)，因此它不單要驗證脫扣特性、工頻耐壓，還要驗證溫升。IEC947_2(以及1997新版IEC60947_2)和我國國家標準GB140482規(guī)定，Ics可以是極限短路分斷能力Icu數(shù)值的25%、50%、75%和**(B類斷路器為50%、75%和**，B類無25%是鑒于它多數(shù)是用于主干線保護之故)。 </p> <p> 上文提到的選擇斷路器的一個重要原則是斷路器的短路分斷能力≥線路的預(yù)期短路電流，這個斷路器的短路分斷能力通常是指它的極限短路分斷能力。 </p> <p> <br /> </p> <p> <br /> 伊頓穆勒塑殼斷路器NZMC1-4-A80一步一步教你安裝塑殼斷路器。</p><div style="width:100%;text-align: center;"><img

<p> <br /> </p> <p> 空氣斷路器的內(nèi)部附件（四） </p> <p> 欠電壓脫扣器：欠電壓脫扣器是在它的端電壓降至某一規(guī)定范圍時，使斷路器有延時或無延時斷開的一種脫扣器，當電源電壓下降(甚至緩慢下降)到額定工作電壓的70%至35%范圍內(nèi)，欠電壓脫扣器應(yīng)運作，欠電壓脫扣器在電源電壓等于脫扣器額定工作電壓的35%時，欠電壓脫扣器應(yīng)能防止斷路器閉合；電源電壓等于或大于85%欠電壓脫扣器的額定工作電壓時，在熱態(tài)條件下，應(yīng)能保證斷路器可靠閉合。因此，當受保護電路中電源電壓發(fā)生一定的電壓降時，能自動斷開斷路器切斷電源，使該斷路器以下的負載電器或電氣設(shè)備免受欠電壓的損壞。使用時，欠電壓脫扣器線圈接在斷路器電源側(cè)，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。

4.過載延時保護：過載延時保護是指負荷電流超過設(shè)備的限定范圍有燒毀設(shè)備的危險，保護裝置能在一定時間內(nèi)切斷電源。過載有個熱量積累的過程，保護動作不需要過于迅速。對于短時過電流，保護不應(yīng)該動作。 </p> <p> 5.隔離功能：隔離功能就是要求斷路器斷開后的泄漏電流不致對人身和設(shè)備產(chǎn)生危害。多次短路跳閘后開關(guān)性能下降，泄漏電流會增大。對人體而言30mA以下為安全漏電電流，而在惡劣的環(huán)境中，超過300mA的泄漏電流持續(xù)2小時以上，就可能使絕緣損壞發(fā)生相地短路進而引發(fā)火災(zāi)。 </p> <p> <br /> </p> <p> <br
