變壓器摘要：變壓器是變電所的主要設(shè)備，功能是實(shí)現(xiàn)電網(wǎng)電壓的等級(jí)變換，基本工作原理是電磁感應(yīng)。變配電所是實(shí)現(xiàn)電壓等級(jí)變換和電能分配的場(chǎng)所。對(duì)供電電源進(jìn)行電壓等級(jí)變換，應(yīng)對(duì)電能進(jìn)行重新分配的場(chǎng)所稱為變電所。建筑變電所是供配電系統(tǒng)的樞紐，供電電源由電網(wǎng)引到變電所，在變電所完成降壓，電能分配等功能。關(guān)鍵詞:變電所；變壓器；繼電保護(hù)；1.介紹要從遠(yuǎn)端發(fā)電廠送出電能，必須應(yīng)用高壓輸電。因?yàn)樽罱K的負(fù)荷，在一些點(diǎn)高電壓必須降低。變壓器能使電力系統(tǒng)各個(gè)部分運(yùn)行在電壓不同的等級(jí)。本文我們討論的原則和電力變壓器的應(yīng)用。2.雙繞組變壓器胡變袋壓卡器碎的汁最汁簡(jiǎn)愈單表形搜式梨包服括辣兩伐個(gè)塵磁謹(jǐn)通躁相醋互鹿耦扔合瓜的鞠固環(huán)定請(qǐng)線示圈句。奉兩叫個(gè)娛線尿圈陷之虛所滋以奏相趟互破耦風(fēng)合停，比是迷因爆為未它近們蠢連傳接權(quán)著歌共養(yǎng)同揮的啊磁矩通侵。防在向電訊力遲應(yīng)訂用擺中使，席使赴用煤層鎖式碑鐵播芯箏變塔壓地器肥(愉本諒文傘中遭提題到林的幻)藝。消變魯壓誤器業(yè)是破高干效徑率吐的弄，舞因宋為謎它瓶沒(méi)捎有與旋捆轉(zhuǎn)些損廈失紡，色因遭此見(jiàn)在嘆電坑壓擁等加級(jí)撤轉(zhuǎn)落換器的銷(xiāo)過(guò)掃程柄中賴，趟能拿量蓬損撕失穗比勞較運(yùn)少澡。棉典繳型粱的穗效揮率皇范廚圍甚在嚇9盒2且到雅9僚9薯%應(yīng)，授上秒限打值艇適壇用巖于膊大講功童率療變買(mǎi)壓團(tuán)器典。焰從騙交青流役電詢?cè)挫`流勉入請(qǐng)電股流侮的宣一板側(cè)有被押稱婆為不變紫壓嚷器詞的歲一川次丙側(cè)妻繞信組酷或啟者愧是通原意邊紫。健它迎在而鐵沸圈應(yīng)中掀建卸立狡了窩磁啟通班φ道，家它縮的足幅部值測(cè)和遠(yuǎn)方臉向浩都響會(huì)茫發(fā)嫌生禾周灑期遼性活的賠變?cè)峄瘋?。逐磁軋通?fù)連倉(cāng)接拴的硬第辨二袖個(gè)總繞星組堵被島稱帶為約變否壓覺(jué)器羊的錯(cuò)二附次梳側(cè)架繞細(xì)組驚或魚(yú)者富是巧副幻邊邊。業(yè)磁銳通優(yōu)是企變惠化究的侮；黑因侍此謝依猴據(jù)孩楞枕次付定資律蝦，斤電擁磁瘡感額應(yīng)歡在缺二愿次菠側(cè)醒產(chǎn)統(tǒng)生娃了他電置壓碎。腿變岔壓或器坦在謎原企邊霉接斜收慮電額能多的撓同帆時(shí)汁也損在況向伸副記邊養(yǎng)所臟帶每的減負(fù)柜荷單輸駐送湖電衡能奴。醬這乳就你是陪變圍壓親器撐的刻作糞用曬。淘3盒.還季變勾壓蛋器萌的道工逢作霉原吉理夢(mèng)當(dāng)也二點(diǎn)次冶側(cè)巾電逝路面開(kāi)姜路攀是賄，頁(yè)即薯使鋤原去邊核被勝施撇以展正慶弦放電余壓陽(yáng)V咬p遷，建也晨是閱沒(méi)塌有醬能織量革轉(zhuǎn)幅移扮的艷。次外微加糕電跡壓芬在膛一打次逐側(cè)筒繞灰組描中鈔產(chǎn)靠生燕一柱個(gè)蓬小屑電宵流貌I源θ燕。歇這障個(gè)薦空蛛載求電覺(jué)流爛有絲兩短項(xiàng)清功筋能柳：塔（長(zhǎng)1父）物在檔鐵范芯討中君產(chǎn)辰生丙電昏磁峰通坑，滴該燈磁乳通夕在旱零農(nóng)和倚φ預(yù)m蘋(píng)之拋間竭做軟正市弦繞變丙化凱，尊φ毀m類(lèi)是沙鐵略芯滿磁偉通褲的鑒最摔大搏值神；挽（張2叢）窩它跑的溜一最個(gè)租分廉量聰說(shuō)梅明鄰了市鐵舟芯扇中異的傻渦來(lái)流倆和汗磁消滯歇損恨耗后。杠這爐兩老種癢相喊關(guān)況的稻損歉耗歪被偶稱謝為耀鐵寶芯釋損栗耗監(jiān)。過(guò)變笑壓尋器安空揭載睜電忠流航I悉θ遙一桿般獸大玻約蛙只地有溝滿羅載址電稠流賀的贏2巧%工—塵5扇%告。孫因春為吸在磚空紐載器時(shí)徐，駕原粘邊貴繞刻組瓜中赴的址鐵備芯末相率當(dāng)昆于勻一緞個(gè)減很傭大堪的插電膨抗覆，峽空堪載嫩電雹流斥的烈相間位壞大酷約慘將萌滯砍后圍于冶原礎(chǔ)邊企電勸壓腰相丑位刺9壽0刮o頂。裹顯精然甩可盜見(jiàn)增電殘流孕分湯量愉I管m綁=每壩I黨0喂s垂i柏n經(jīng)θ煩0桐，梨被壤稱娛做草勵(lì)廚磁景電陰流的，醉它缺在群相陡位獸上糕滯室后懇于要原鳳邊做電蓄壓侵V牽P接邪9桶0世o周。牧就掛是裙這課個(gè)足分隨量民在陸鐵眨芯鉗中架建廈立袍了幸磁值通浩；姜因巧此利磁幸通罷φ顏與連I壇m場(chǎng)同域相泄。眠第章二摩個(gè)靠分略量警I捉e帳=鳥(niǎo)I葛0禿s款i但n姿θ字0伴，號(hào)與樹(shù)原憲邊偵電閣壓晝同勾相渾。拆這壘個(gè)囑電康流最分襪量隙向染鐵憑芯學(xué)提畏供歉用腫于增損星耗炭的適電北流聞。族兩居個(gè)渠相錘量蹦的慢分虜量出和獵代芬表苦空渡載軋電弱流賢，纏即并I虹0擊=取健I彎m球+勉此I怨e半應(yīng)槽注現(xiàn)意趕的巖是編空膝載華電宮流蠶是世畸庫(kù)變?nèi)焙蛦谭潜┱异栃伪氖Ｄ圻@幼種險(xiǎn)情薄況掏是簡(jiǎn)非錄線拘性少鐵約芯勇材掙料錦造萄成瞎的詳。局如中果拔假野定摔變光壓山器斗中項(xiàng)沒(méi)銹有義其華他餐的刊電今能風(fēng)損畝耗醬一適次仆側(cè)察的恐感候應(yīng)謹(jǐn)電嶺動(dòng)偏勢(shì)燒E秀p好和押二遵次溜側(cè)扒的話感荒應(yīng)畏電摧壓博E熱s夏可倍以殃表芹示修出牙來(lái)肌。月因扭為硬一借次壞側(cè)赤繞溝組毒中奪的窯磁獨(dú)通蘆會(huì)星通看過(guò)康二翁次親繞袍組妖，介依莖據(jù)夫法沃拉溫第被電缸磁司感朝應(yīng)蟻定占律茂，西二而次慨側(cè)壞繞乳組籌中假將霞產(chǎn)條生趣一鬧個(gè)政電蓋動(dòng)駁勢(shì)恥E體，控即侍E務(wù)=客N柔Δ胸φ向/凡Δ作t鉆。陵相述同階的矩磁楊通愧會(huì)恐通種過(guò)艇原銹邊癢自莊身討，脫產(chǎn)擊生把一端個(gè)運(yùn)電奔動(dòng)忘勢(shì)韻E盆p萬(wàn)。據(jù)正晌如之前抹文浴中腔討醋論蜜到捆的脅，看所秧產(chǎn)逼生技的遠(yuǎn)電偉壓混必盒定槳滯集后桐于趣磁溝通肢9宜0陰o爸，真因讓此桐，燭它犯于沙施揚(yáng)加瀉的襲電魚(yú)壓檔有改1朽8疼0忽o捧的耍相適位吐差伴。鉆因亮為規(guī)沒(méi)鼻有豪電蹦流掌流協(xié)過(guò)冊(cè)二遲次沫側(cè)濫繞踢組醋，礎(chǔ)E茄s帳=擺V激s蛋。風(fēng)一儲(chǔ)次領(lǐng)側(cè)哄空弱載浸電爹流乘很犁小斤，栗僅輩為抹滿舌載枝電旨流挎的滋百待分葉之反幾色。芳因陜此榆原禿邊蝶電禍壓吹很它小船，為并間且研V襯p嫩的蘿值屠近斑乎珍等厲于愧E努p攔。腳原含邊傳的聚電距壓窗和持它贊產(chǎn)靜生役的投磁背通續(xù)波房形克是毒正斥弦聾形薦的井；刮因現(xiàn)此辦產(chǎn)顯生甘電幣動(dòng)弓勢(shì)置E筑p性和歐E佛s畜的糠值裙是乎做菠正勻弦胡變盛化亞的斥。和產(chǎn)礦生旗電鈔壓鞠的野平準(zhǔn)均壺值編如視下耳E銹a招v哲g灑=定t腿u串r肢n季s符×悟即鋒是須法員拉曲第罩定件律催在謹(jǐn)瞬墊時(shí)脅時(shí)艱間蒸里選的堆應(yīng)處用莫。姜它遞遵遣循益E卸a餃v餓g膚=閱N討=剝4把f系N格φ根m濫其蔑中芬N討是氣指蹦線靜圈尿的側(cè)匝究數(shù)惱。嶼從瘡交世流冶電肚原丸理丘可促知耍，龜有截效罷值柄是址一蘇個(gè)介正妹弦炸波雁，膀其催值果為嶺平糖均臣電拴壓恐的樹(shù)1舒.債1儀1蘇倍三；屋因踐此紀(jì)E芝=誕4材.幟4侄4架f鉗N約φ霉m澇因奇為剝一品次堆側(cè)概繞毫組哈和膚二晨次壟側(cè)久繞紋組泡的懸磁蜜通缺相樹(shù)等海，需所勤以促繞暮組眨中丸每著匝芳的訓(xùn)電許壓文也跡相嚴(yán)同怪。脊因斬此懷E罵p虎=宏4滾.柜4肺4油f阿N股p預(yù)φ逐m副并議且祥E篩s鍵=炎4攔.演4俗4汗f剩N煮s唱φ蕩m印其蜘中兔N刻p女和漁E妙s駛是再一胳次鉛側(cè)筆繞括組遠(yuǎn)和終二低次償側(cè)球繞御組弟的濃匝黎數(shù)預(yù)。粗一缸次很側(cè)猶和坐二銅次謙側(cè)炭電誼壓嘉增竹長(zhǎng)應(yīng)的棉比言率憐稱賴做悄變豐比盆。稈用架字媽母?jìng)鱝役來(lái)里表近示隔這起個(gè)喘比洪率上，凱如僑下蛇式蒙a令=違=竊假站設(shè)竊變共壓出器恐輸條出拴電岡能鼓等么于厘其遺輸?shù)胄揠娔灸苣蟆洝犨@焰?zhèn)€嫁假起設(shè)研適假用惕于吃高增效排率勵(lì)的奏變亞壓蹦器岸。鎮(zhèn)實(shí)軍際撥上酬我寄們到是仗考鐘慮前一箭臺(tái)冷理梨想鼓狀勸態(tài)社下嶄的本變虎壓之器梅；汗這惰意康味額著沿它置沒(méi)咸有被任緒何薯?yè)p嚼耗頁(yè)。領(lǐng)因攏此歷P港m榴=鼠P堂o脾u蛾t摔或轟者見(jiàn)V鄉(xiāng)p固I簡(jiǎn)p草×臨諷p流r卸i虧m千a友r不y御亦P徒F水侍=沿掌V閘s角I辯s滿×件飾s普e寒c決o醒n膚d流a俱r狗y集覆P匯F懂這屠里兩P稻F恨代卵表蜜功鳴率益因叛素炭。乳在兼上辱面敗公嚼式策中螞一路次默側(cè)候和毛二獎(jiǎng)次秘側(cè)得的鍛功做率回因稅素匙是撒相成等許的傾；魯因旁此盟V庫(kù)p田I紙p跳川=映驗(yàn)V煌s次I雄s床從升上巡式嗓我川們星可緞以舌得軌知繭認(rèn)=詢?！珍h≌燕楊a曲它舅表框明束端廚電選壓河比千等皮于哥匝碎數(shù)波比艇，細(xì)換弊句竊話痕說(shuō)弦，凡一茄次辛側(cè)充和千二悉次亦側(cè)添電慢流耗比瓦與僅匝堂數(shù)河比瞎成雄反丹比碰。舊匝匹數(shù)球比叉可另以爬衡段量亭二救次碗側(cè)被電勇壓衫相估對(duì)園于供一儲(chǔ)次庸惻虹電陣壓密是家升徹高殘或狡者適是脹降特低寧。艷為庫(kù)了鉤計(jì)辮算枕電喂壓雕，晶我普們甘需嬸要征更繩多膚數(shù)拴據(jù)遠(yuǎn)。偶終前端寨電月壓漏的濁比哈率浴變璃化遺有且些韻根假據(jù)慈負(fù)筒載撲和揀它濁的謎功緊率娃因逐素貝?？蹖?shí)塵際翠上影,挪乓變木比膜從孕標(biāo)恨識(shí)冠牌潛數(shù)倘據(jù)趟獲活得社,告川列寇出犯在武滿胖載薄情著況賺下借原塌邊把和媽副冤邊澤電落壓掘?？恿щA巷脹當(dāng)燕副例邊輪電鼓壓雷V洪s附相鑒對(duì)班于用原磚邊變電即壓總減株小局時(shí)炒，喘這蘭個(gè)述變脊壓掏器綠就跡叫播做緒降皇壓銷(xiāo)變娘壓持器陷。驢如凈果槽這情個(gè)登電拋壓屑是沙升老高婦的曉，稈它斑就郊是搖一現(xiàn)個(gè)蘆升壓壓巨變寬壓株器獨(dú)。緞在杰一偶個(gè)坑降栽壓類(lèi)變竹壓海器很中嘗傳旗輸墓變蓄比吩a筆遠(yuǎn)隨大籠于英1幻(肺a秧>湯1默.沫0鞠)嘆，啞同模樣竹的紛，團(tuán)一側(cè)個(gè)測(cè)升旬壓烘變素壓劍器耗的眉變庸比屑小盜于朋1撿(揉a悼<炭1取.杜0念)擋。冰當(dāng)日a母=掀1順時(shí)謹(jǐn)，卻變棕壓扛器傭的就二昏次觸側(cè)分電患?jí)喝本推娴壬徲诟羝饚熞晃榇蚊}側(cè)冊(cè)電盾壓診。教這罩是膠一插種
