中國已經發展成為西門子**重要的研發**。截至2016財年(2015年10月1日至2016年9月30日),西門子在中國擁有4500多名研發人員,20個研發中心以及超過11000項有效專利和專利申請。目前,西門子中國研究院的研發機構遍布北京、上海、蘇州、南京、武漢、無錫、青島、天津等地。2016年初,西門子推出“西門子中國創新中心”計劃,在自主系統、工業大數據分析、工業物聯網、智慧交通、工業信息安全、數字化企業、數字化電廠等領域推進數字化創新。
此外,西門子在中國不遺余力地打造開放的創新生態系統,攜手當地政府、**企業、中、小、微及初創企業,以及大學和科研機構,共同發展面向未來的創新,實現多方共贏。西門子在研發領域與中國87所高校和教育機構合作,與清華大學建立知識交流中心(CKI)戰略合作關系,促進雙方在科研技術和人才培養方面的交流與合作。
**財經傳媒跨國公司中國創新**實踐大獎作為年度評選,關注分布在不同領域的基礎技術與核心技術的投入與發展,衡量跨國公司在中國實現技術創新,以及這些創新在中國、其他國家與地區產生的影響,旨在表彰對創新做出巨大貢獻的企業。《環球科學》創新榜單旨在表彰在科技創新方面表現突出、對中國本土創新有重要推動作用、研發實力處于行業**地位,并保持較高成長性的本土和跨國企業
低壓斷路器用作交、直流線路的過載、短路保護,被廣泛應用于建筑照明、動力配電線路、用電設備作為控制開關和保護設備,也可用于不頻繁起動電動機以及操作或轉換電路
1.種類
(1)式斷路器
(2)塑料外殼式斷路器
(3)電動斥力式限流斷路器
(4)剩余電流保護斷路器
(5)直流快速斷路器
(6)滅磁斷路器
2.低壓斷路器的選用要點
表示低壓斷路器性能的主要指標有分斷能力和保護特性。
分斷能力是指開關在指定的使用和工作條件及在規定的電壓下接通和分斷的大電流值(kA)。
保護特性主要分為過電流保護、過載保護和欠電壓保護三種。
(1)額定電壓
斷路器的額定電壓應大于線路額定電壓。主要是交流380V或直流220V的供電系統。按線路額定電壓進行選擇時應滿足下列條件:
(4-10-5)
式中 ——低壓斷路器的額定電壓,V;
——線路的額定電壓,V。
