According to its voltage, it can be classified into hightension switchgear and lowtension switchgear. While according to its installation sites, it can be divided into outdoor switchgear and indoor switchgear. Besides, it can also be classified into stationary switchgear and handpush switchgear according to its mobility of the breaker. The switchgear is a bination of various highlow tension electric, measuring instruments, electric safeguards and control switches which function as a distinct performance. Generally, switchgear can form a circuit, which could cooperate with other switchgear and realized distinct function. Switchgear possesses versatile advantages. Structurally, the clapboards are used to separate the room in switchgear, which shaped several individual small spaces. Such independent small spaces can depart the hightension switch, isolating shutters, relay protecting as well as measuring instruments each other, which is in favor of restricting the enlargement of shortcircuit accident, and convenient to repair and maintain. Hightension switchgear is suitable for not only generating electricity, transmission electricity, distributing HXGN12型高壓開關(guān)柜設(shè)計 II electricity, electricity transition in electrical system but also the switch, control and protection in electricity depletion. The hightension switchgear is a kind of electric equipment with the voltage range from 36 KV to 550KV, which mainly include hightension cutout, hightension isolator switch, earthing switch, hightension load switch, hightension autoregistration and sectionalizer, hightension operating mechanism, hightension antiexplosion power distribution unit and hightension switch. What’s more, lowtension switchgear is mainly used in industry such as power station, petroleum, chemical industry, metallurgy, spinning and highrise buildings which function as electricity transition equipment in transmission and distribution of electricity. Key words: HXGN12 hightension switchgear。低壓開關(guān) 柜 用于發(fā)電廠 、 石油、化工、冶金、紡織、高層建筑等行業(yè) 。電壓等級在 36KV 到 550KV 的電氣設(shè)備 。 這樣有利于限制短路事故的擴大 ， 也便于檢修維護。開關(guān)柜有以下優(yōu)點，從結(jié)構(gòu)來看開關(guān)柜內(nèi)的空間用隔板分隔 ， 成許多獨立的小間 。將各種高低壓電氣、測量儀表、保護電氣和控制開關(guān)集中在一個柜子里 的裝置，并能達到特定性能的柜子稱為開關(guān)柜。 畢 業(yè) 論 文 HXGN12 型高壓開關(guān)柜設(shè)計 作 者 姓 名 ： 丁 龍 龍 專 業(yè)、班 級 ： 發(fā)電廠及電力系統(tǒng) 、 1002 學(xué) 號 ： 2021110838 校內(nèi)指導(dǎo)教師 ： 丁 燕 校外指導(dǎo)教師 ： 何 文 麗 完 成 日 期 ： 2 0 1 3 / 6 /1 1 黃河水利職業(yè)技術(shù)學(xué)院自動化工程系 黃河水院自動化工程系畢 業(yè)論文 I 摘要 開關(guān)柜用于電力配電系統(tǒng)，一般作為發(fā)送、接受、分配電能之用，按電壓等級的高低可分為高壓開關(guān)柜和低壓開關(guān)柜，按裝置地點的不同可分為戶外式和戶內(nèi)式兩種。按斷路器是否能動又可分為固定式和手車式。一般一個柜子構(gòu)成一個回路，可以與別的柜子配合使用，達到某一特定的功能。 使高壓開關(guān)、隔離刀閘、繼電保護和測量儀表都互相分隔開 。高壓開關(guān)柜適用于電力系統(tǒng)發(fā)電、 輸電、配電、電能轉(zhuǎn)換和消耗中起通斷、控制、保護等作用。主 要包括高壓斷路器、高壓隔離開關(guān)、接地開關(guān)、高壓負荷開關(guān)、高壓自動重合與分段器 ， 高壓操作機構(gòu) 、 高壓防 爆配電裝置和高壓開關(guān)等幾大類。 作為輸電配電等電能轉(zhuǎn)換之用。 Circuit diagram, design need to be noticed。 ....................................24 開關(guān)柜的結(jié)構(gòu)布置 ........................................................24 外殼設(shè)計 ................................................................25 互感器的設(shè)計 ............................................................25 HXGN12型高壓開關(guān)柜設(shè)計 II 隔離開關(guān)和接地開關(guān) ......................................................25 測量儀表、繼電保護裝置及輔助回路設(shè)計 ....................................25 、試驗 ............................................................27 耐壓試驗 ................................................................27 絕緣電阻測試試驗 ........................................................27 ......................................................29 在運行中突然跳閘故障的判斷和處理 ........................................29 儲能故障的判斷和處理 ....................................................29 合閘故障的判斷和處理 ....................................................29 分閘故障的判斷和處理 ....................................................30 總 結(jié) ........................................................................31 致 謝 ........................................................................32 參 考 文 獻 ................................................................33 附 錄 ： ......................................................................34 HXGN12型高壓開關(guān)柜設(shè)計 1 緒論
