中國(guó)已經(jīng)發(fā)展成為西門子**重要的研發(fā)**。截至2016財(cái)年(2015年10月1日至2016年9月30日),西門子在中國(guó)擁有4500多名研發(fā)人員,20個(gè)研發(fā)中心以及超過(guò)11000項(xiàng)有效專利和專利申請(qǐng)。目前,西門子中國(guó)研究院的研發(fā)機(jī)構(gòu)遍布北京、上海、蘇州、南京、武漢、無(wú)錫、青島、天津等地。2016年初,西門子推出“西門子中國(guó)創(chuàng)新中心”計(jì)劃,在自主系統(tǒng)、工業(yè)大數(shù)據(jù)分析、工業(yè)物聯(lián)網(wǎng)、智慧交通、工業(yè)信息安全、數(shù)字化企業(yè)、數(shù)字化電廠等領(lǐng)域推進(jìn)數(shù)字化創(chuàng)新。
此外,西門子在中國(guó)不遺余力地打造開(kāi)放的創(chuàng)新生態(tài)系統(tǒng),攜手當(dāng)?shù)卣?*企業(yè)、中、小、微及初創(chuàng)企業(yè),以及大學(xué)和科研機(jī)構(gòu),共同發(fā)展面向未來(lái)的創(chuàng)新,實(shí)現(xiàn)多方共贏。西門子在研發(fā)領(lǐng)域與中國(guó)87所高校和教育機(jī)構(gòu)合作,與清華大學(xué)建立知識(shí)交流中心(CKI)戰(zhàn)略合作關(guān)系,促進(jìn)雙方在科研技術(shù)和人才培養(yǎng)方面的交流與合作。

2.(2)把額定條件下的開(kāi)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(guó)根據(jù)國(guó)際電工委員會(huì)(IEC)的規(guī)定,現(xiàn)只把額定開(kāi)斷電流作為表征開(kāi)斷能力的參數(shù),而斷流容量?jī)H作為描述斷路器特性的一個(gè)數(shù)值。
3.關(guān)合能力
說(shuō)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(shí),瞬態(tài)電流個(gè)大半波峰值來(lái)表示,制造部門對(duì)關(guān)合電流一般取額定開(kāi)斷電流的 倍即
(4-10-1)
式中 ——額定關(guān)合電流,kA;
——額定開(kāi)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(dòng)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(shí)短路電流作用的能力,簡(jiǎn)稱耐受能力。
(1)短時(shí)熱電流(熱穩(wěn)定電流) 在規(guī)定的時(shí)間內(nèi)(規(guī)定標(biāo)準(zhǔn)時(shí)間為2s,需要大于2s時(shí)推薦4s)斷路器在合閘位置,可能經(jīng)受的短時(shí)熱電流有效值(kA),稱為短時(shí)熱電流(或短時(shí)耐受電流),斷路器標(biāo)準(zhǔn)中規(guī)定
(4-10-2)
短時(shí)熱電流通過(guò)斷路器時(shí),各零部件的溫度不應(yīng)超過(guò)短時(shí)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)行的異常現(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(dòng)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(shí)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(shí)通過(guò)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(gè)大半波峰值電流來(lái)表示,且
