聯鎖裝置有機械聯鎖和電氣聯鎖兩種類型。工作原理是： </p> <p> （1）機械聯鎖裝置一般使用鋼絲繩或者杠桿機構，以機械位置的變動（也可采用多功能程序鎖）來保證在斷路器切斷電源以前，隔離開關的操作把手不能動作。 </p> <p> （2）電氣聯鎖裝置電氣聯鎖一般有兩種聯鎖方式，一種是通過操作機構上的聯動輔助接點（常開或常閉）去控制隔離開關的把手。當斷路器未斷開時，隔離開關操作把手不能動作。 </p> <p> 另一種電氣聯鎖是利用距離開關操作機構上的聯動輔助接點（常開或常閉）去控制斷路器。當拉動隔離開關的把手時，聯動輔助接點（常開或常閉）使斷路器動作以切斷電路，從而可防止帶負荷拉動距離開關的事故。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <strong>塑殼式斷路器</strong>如何選型（二） </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> 斷路器額定電流是指斷路器中的脫扣器能長期通過的電流，又稱斷路器脫扣器額定電流。 </p> <p> 同一系列中有多種殼架等級額定電流，同一殼架等級額定電流中又有多種額定電流。 </p> <p> 例如DZ20系列中有100、225、400、630、800、1250等殼架等級額定電流，而100殼架等級額定電流中有16A、20A、25A、32A、40A、50A、63A、80A、100A額定電流；225A殼架等級額定電流中有100A，125A、160A、180A、200A、225A額定電流。 </p> <p> <br /> </p> <p> <br />

<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> <p> <strong>塑殼式斷路器</strong>如何選型（六） </p> <p> 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> 額定運行短路分斷能力是指規(guī)定條件下的分斷能力。按規(guī)定的試驗程序之后，須考慮斷路器繼續(xù)承載它的額定電流。 </p> <p> 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> <br />
