2.(2)把額定條件下的開斷能力稱為額定斷流容量。三相電路的額定斷流容量,以
(MVA)表示。
我國根據(jù)國際電工委員會(IEC)的規(guī)定,現(xiàn)只把額定開斷電流作為表征開斷能力的參數(shù),而斷流容量僅作為描述斷路器特性的一個數(shù)值。
3.關(guān)合能力
說明斷路器關(guān)合短路故障能力的參數(shù)為額定關(guān)合電流。其數(shù)值以關(guān)合操作時,瞬態(tài)電流個大半波峰值來表示,制造部門對關(guān)合電流一般取額定開斷電流的 倍即
(4-10-1)
式中 ——額定關(guān)合電流,kA;
——額定開斷電流,kA。
斷路器關(guān)合短路電流的能力除與滅弧裝置性能有關(guān)外,還與斷路器操動機(jī)構(gòu)的合閘功率的大小有關(guān)。
耐受性能
斷路器應(yīng)具有足夠的耐受短時短路電流作用的能力,簡稱耐受能力。
(1)短時熱電流(熱穩(wěn)定電流) 在規(guī)定的時間內(nèi)(規(guī)定標(biāo)準(zhǔn)時間為2s,需要大于2s時推薦4s)斷路器在合閘位置,可能經(jīng)受的短時熱電流有效值(kA),稱為短時熱電流(或短時耐受電流),斷路器標(biāo)準(zhǔn)中規(guī)定
(4-10-2)
短時熱電流通過斷路器時,各零部件的溫度不應(yīng)超過短時發(fā)熱高允許溫度,且不致出現(xiàn)觸頭熔接或軟化變形,以及其它妨礙正常運(yùn)行的異?,F(xiàn)象。允許發(fā)熱高溫度數(shù)值隨材料而異。
(2)峰值耐受電流 峰值耐受電流亦稱動穩(wěn)定電流,即在規(guī)定的使用條件和性能下,斷路器在合閘位置時所能經(jīng)受的電流峰值。它與關(guān)合電流不同的是,峰值耐受電流是斷路器處于合閘位置時通過的短路電流,而關(guān)合電流則是由于斷路器關(guān)合短路故障所產(chǎn)生的短路電流。峰值耐受電流也是以短路電流的個大半波峰值電流來表示,且
