【正文】 220kV 變電站電氣主控制系統(tǒng)二次回路設(shè)計(jì) I 摘 要 本論文介紹了文關(guān) 220kV 降壓變電站電氣部分初步設(shè)計(jì)，從設(shè)計(jì)任務(wù)上來(lái)看，共分為七大步驟。即， 電氣控制方式選擇及確定。 互感器回路設(shè)計(jì)。 主斷路器控制及信號(hào)回路設(shè)計(jì)。 變電站繼電保護(hù)配置設(shè)計(jì)。 進(jìn)行本變電站高壓配電裝置的規(guī)劃設(shè)計(jì)。 進(jìn)行本變電站繼電保護(hù)設(shè)計(jì)。 變電站自動(dòng)裝置配置設(shè)計(jì)等七大步驟，本論文結(jié)合電氣的有關(guān)規(guī)程進(jìn)行設(shè)計(jì)。本次設(shè)計(jì)是我們?cè)谛Ｆ陂g進(jìn)行的最后一個(gè)非常重要的綜合性實(shí)踐教學(xué)環(huán)節(jié)，也是我們學(xué)生全面運(yùn)用所學(xué)基礎(chǔ)理論、專(zhuān)業(yè)知識(shí)對(duì)實(shí)際問(wèn)題進(jìn)行設(shè)計(jì)（或研究）的綜合性訓(xùn)練，同時(shí)還是 我們將來(lái)走向工作崗位而奠定的基本實(shí)踐。通過(guò)本次設(shè)計(jì)可以增強(qiáng)我們運(yùn)用所學(xué)知識(shí)解釋實(shí)際問(wèn)題的能力和創(chuàng)新能力，以便更好地適應(yīng)工作的需要。其設(shè)計(jì)內(nèi)容結(jié)合相關(guān)的參考文獻(xiàn)進(jìn)行編寫(xiě)，由于水平有限，難免會(huì)有錯(cuò)誤疏漏之處，請(qǐng)參閱老師多給予批評(píng)指正。 關(guān)鍵詞： 變電站 ,電氣主接線 ,電氣設(shè)備 ,防雷保護(hù)等。 沈陽(yáng)工程學(xué)院畢業(yè)設(shè)計(jì)（論文） II Abstract This paper introduced the buck, Commissioner of 220 kV electric substation of the preliminary design, design tasks from the point of view, is divided into seven steps. That is, 1, choice of the main transformer substation of the models, capacity and number of Taiwan. 2, the design of the electrical substation main connection of the basic form. 3, a shortcircuit current calculation. 4, a major electrical equipment choice. 5, the highvoltage power distribution substation planning and design of the devices. 6, the substation protection and automatic devices of the planning and design. 7, Lightning Protection of the substation planning and design, such as seven steps, this paper with the electrical design on a point of order. The design is in school during the last a very important part of a prehensive practice teaching, but also full use of our students have learned basic theories, professional knowledge to practical problems to design (or research) integrated training, is also our future Jobs and to lay the basic practice. Through this design can be enhanced by the knowledge we use to explain the actual capacity and ability to innovate in order to better meet the needs of their work. The design elements associated with the reference to the preparation, the limited level, it is inevitable there will be errors of omission, please refer to the teacher to give more criticism correction. Keyword: substations, the main electrical wiring and electrical equipment, mine protection. 220kV 變電站電氣主控制系統(tǒng)二次回路設(shè)計(jì) 目 錄 摘 要 ..............................................................................................................................................
