空氣斷路器，又名空氣開關(guān)，是斷路器的一種。是一種只要電路中電流超過額定電流就會自動斷開的開關(guān)。空氣開關(guān)是低壓配電網(wǎng)絡(luò)和電力拖動系統(tǒng)中非常重要的一種電器，它集控制和多種保護功能于一身。除能完成接觸和分斷電路外，尚能對電路或電氣設(shè)備發(fā)生的短路、嚴重過載及欠電壓等進行保護，同時也可以用于不頻繁地啟動電動機。 </p> <p> 空氣斷路器的主要作用 </p> <p> 在正常情況下，過電流脫扣器的銜鐵是釋放著的；一旦發(fā)生嚴重過載或短路故障時，與主電路串聯(lián)的線圈就將產(chǎn)生較強的電磁吸力把銜鐵往下吸引而頂開鎖鉤，使主觸點斷開。欠壓脫扣器的工作恰恰相反，在電壓正常時，電磁吸力吸住銜鐵，主觸點才得以閉合。一旦電壓嚴重下降或斷電時，銜鐵就被釋放而使主觸點斷開。當電源電壓恢復正常時，必須重新合閘后才能工作，實現(xiàn)了失壓保護。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <strong>塑殼斷路器</strong>各種分斷能力關(guān)系（四） </p> <p> 額定運行短路分斷能力(Ics)，是指在一定的試驗參數(shù)(電壓、短路電流和功率因數(shù))條件下，經(jīng)一定的試驗程序，能夠接通、分斷的短路電流，經(jīng)此通斷后，還要繼續(xù)承載其額定電流的分斷能力，它的試驗程序為O—t（線上）CO—t(線上)CO。 </p> <p> 短時耐受電流(Icw),是指在一定的電壓、短路電流、功率因數(shù)下，忍受0.05、0.1、0.25、0.5或1s而斷路器不允許脫扣的能力，Icw是在短延時脫扣時，對斷路器的電動穩(wěn)定性和熱穩(wěn)定性的考核指標，它是針對B類斷路器的，通常Icw的最小值是：當In≤2500A時，它為12In或5kA，而In＞2500A時，它為30kA(DW45_2000的Icw為400V、50kA，DW45_3200的Icw為400V、65kA)。

輔助觸頭：輔助觸頭是斷路器主電路分、合機構(gòu)機械上連動的觸頭，主要用于斷路器分、合狀態(tài)的顯示，接在斷路器的控制電路中通過斷路器的分合，對其相關(guān)電器實施控制或聯(lián)鎖。例如向信號燈、繼電器等輸出信號。塑殼斷路器殼架等級額定電流100A為單斷點轉(zhuǎn)換觸頭，225A及以上為橋式觸頭結(jié)構(gòu)，約定發(fā)熱電流為3A；殼架等級額定電流400A及以上可裝兩常開、兩常閉，約定發(fā)熱電流為6A。操作性能次數(shù)與斷路器的操作性能總次數(shù)相同。

4)欠電壓脫扣器用作線路及電源設(shè)備的久電壓保護，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。使用者應(yīng)確認線路與欠電壓脫扣器的工作電壓是否一致。欠電壓的工作范圍為(70％～35％)Un。欠電壓脫扣器也有多種額定工作電壓和不同電源頻率，可供不同場合，不同電源時選用。 </p> <p> 5)電動操作機構(gòu)用于斷路器的自動控制和遠距離的閉合和斷開之用。有電動操作機構(gòu)和電磁操作機構(gòu)兩種：電動操作機構(gòu)由電動機驅(qū)動，一般適用于殼架等級額定電流400A及以上斷路器，電磁鐵操作機構(gòu)適用于殼架等級額定電流225A及以下斷路器。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p>
