隨著“制造2025”“互聯(lián)網(wǎng)+”“網(wǎng)絡強國”等戰(zhàn)略的深入實施，通信及自動控制技術(shù)、傳
感技術(shù)等信息技術(shù)快速發(fā)展、不斷滲透應用，“數(shù)字工廠”概念應運而生。
通信設(shè)備制造業(yè)迎轉(zhuǎn)型拐點
信息通信行業(yè)是國民經(jīng)濟基礎(chǔ)性、戰(zhàn)略性、先導性產(chǎn)業(yè)，對我國經(jīng)濟轉(zhuǎn)型升級有著重要的支撐作用，
而通信設(shè)備制造業(yè)為信息通信行業(yè)提供基礎(chǔ)設(shè)施，是其基礎(chǔ)性領(lǐng)域。
通信設(shè)備制造業(yè)呈現(xiàn)出以下特點：產(chǎn)業(yè)鏈鏈條清晰，產(chǎn)業(yè)規(guī)模和新產(chǎn)品市場空間以技術(shù)發(fā)展為爆發(fā)點
；需求方規(guī)模經(jīng)濟效應突出；對其他行業(yè)出高滲透性；市場競爭日趨加大，行業(yè)需求，利潤

4．峰值耐受電流反映了斷路器承受由于短路電流產(chǎn)生電動力的耐受性能，它決定斷路器的導電部分和絕緣支撐件的機械強度以及觸頭的結(jié)構(gòu)形式。
5．操作性能
（1）全開斷時間 是指斷路器接到分閘命令瞬間起到電弧熄滅為止的時間間隔。即
（4-10-4）
式中 ——全開斷時間，s；
——分閘時間，s；從斷路器接到分閘命令瞬間到
所有相的觸頭都分離的時間間隔，亦稱為斷
路器固有分閘時間；
——燃弧時間，s；是指某一相首先起弧瞬間到所
有相電弧全部熄滅的時間間隔。
全開斷時間是說明斷
路器開斷過程快慢的主
要參數(shù)，它直接影響故
障對設(shè)備的損壞程度、
故障范圍、傳輸容量和
系統(tǒng)的穩(wěn)定性。 斷路器開斷時間示意圖
（2）合閘時間 處于分閘位置的斷路器，從接
到合閘命令瞬間起到所有相的觸頭均接觸為止的
時間稱為合閘時間。
6．自動重合閘性能
自動重合閘的操作循環(huán)：分— —合分— —合分。 為斷路器開斷故障電路，從電弧熄滅起到電路重新接通的時間，稱為無電流間隔時間，一般為0.3s或0.5s； 為強送電時間，一般為180s。
斷路器開斷時間與無電流間隔時間之和稱為自動重合閘時間。
金屬短接時間系指斷路器重合閘操作后，觸頭閉合到第二次觸頭分開所需用的時間。
