In this thesis , the design plan of the intelligent combined substation is discussed in details 本文介紹了“智能型箱式變電站”的設(shè)計(jì)方案。
The intelligent box - type substation is covered by zinc . the main bus is located in a room , separated with the lokv switchgear 文中所述智能型箱式開關(guān)站,其外殼型鋼經(jīng)過熱鍍鋅處理。
Based on characteristic value buckle analysin method of finite elements theory , this paper analyzes and calculates the main working condition of bridge erecting machine jq600 with box cross section beam 摘要本文根據(jù)有限元理論中的特征值屈曲分析方法,對jq600型箱梁架橋機(jī)的主要工況進(jìn)行了穩(wěn)定性分析計(jì)算。
Based on the literature reviewing , the current situation and existing problems are introduced . a design idea about intelligent box - type substation is proposed to solve the existing problems 本文在查閱大量文獻(xiàn)資料的基礎(chǔ)上,介紹了我國電網(wǎng)改造的現(xiàn)狀及存在的問題,并針對這些問題提出了智能型箱式開關(guān)站的設(shè)計(jì)思路。
An auxiliary switch is added , it is integrated with handler of the isolation switch , grounding switch . the maintenance for the auxiliary switch can be carried out in the maintenance room . there are interlock between the door and isolation switch or the grounding switch , only after the isolation switch is open or the grounding switch is closed , the door can be opened , it is the unique characteristics of the substation 另外我們生產(chǎn)的智能型箱式開關(guān)站采用了強(qiáng)制性的jsxgn型的機(jī)械閉鎖;為了簡化結(jié)構(gòu),提高可靠性,也對其進(jìn)行了設(shè)計(jì)改進(jìn):增加了輔助開關(guān),使其與隔離開關(guān)、接地開關(guān)的操作手柄為一體,并可在維護(hù)走廊對輔助開關(guān)進(jìn)行檢修;箱體的門板與隔離開關(guān)或接地開關(guān)之間也有連鎖,只能在隔離開關(guān)打開后或接地開關(guān)閉合后,才能被打開;此結(jié)構(gòu)也是本開關(guān)站所獨(dú)有。
