額定控制電源電壓是塑殼斷路器裝分勵脫扣器及電動機構(gòu)附件時的電壓。有交流和直流兩種電壓，選用時一定注明交流或直流。 </p> <p> 額定極限短路分斷能力是指規(guī)定條件下的分斷能力。按規(guī)定的試驗程序動作之后，不考慮斷路器繼續(xù)承載它的額定電流。 </p> <p>

NZM塑殼斷路器NZMS3-ME350，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(guān)廠CM1-100分為C基本型(25～35kA)、L標準型(35～50kA)，ETAON

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。 </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，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 /> 一步一步教你安裝塑殼斷路器。</p><div style="width:100%;text-align: center;"><img style="max-width:

</p> <p> <strong>塑殼斷路器</strong>的接線方式（一） </p> <p> 斷路器的接線方式有板前、板后、插入式、抽屜式，用戶如無特殊要求，均按板前供貨，板前接線是常見的接線方式。 </p> <p> 1、板后接線方式：板后接線比較大特點是可以在更換或維修斷路器，不必重新接線，只須將前級電源斷開。由于該結(jié)構(gòu)特殊，產(chǎn)品出廠時已按設(shè)計要求配置了**安裝板和安裝螺釘及接線螺釘，需要特別注意的是由于大容量斷路器接觸的可靠性將直接影響斷路器的正常使用，因此安裝時必須引起重視，嚴格按制造廠要求進行安裝。 </p> <p> <br /> </p> <p> <br />

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(chǎn)生電弧，相當(dāng)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(yīng)、電動效應(yīng)和熱效應(yīng)對斷路器和用電設(shè)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(dǎo)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(shè)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(shè)備，有較高的抗沖擊電流能力。 ETAON NZM塑殼斷路器NZMS3-ME350</p><p
