Kutarisisa uye kushandiswa kwebhokisi remhando substation
Bhokisi mhando substation, inozivikanwawo seyekunze yakakwana substation, inozivikanwawo seyakasanganiswa substation, inokosheswa zvakanyanya nekuda kwezvakanaka zvayo senge flexible musanganiswa, kufambisa kuri nyore, kutama, kuisirwa nyore, nguva pfupi yekuvaka, mutengo wakaderera wekushanda, nzvimbo diki yepasi, kusvibiswa. -kusununguka, kuchengetedza kusununguka, nezvimwewo Mukuvaka (shanduko) yemagetsi emagetsi ekumaruwa, inoshandiswa zvakanyanya mukuvaka nekushandura kwemaguta uye kumaruwa 10 ~ 110kV zviteshi zviduku uye zvepakati (kugovera), mafekitari nemigodhi, uye mobile operation substations.Nekuti zviri nyore kupinda mukati menzvimbo yekuremerwa, kuderedza magetsi emagetsi, uye kugadzirisa iyo terminal voltage quality, inonyanya kukodzera kushandurwa kwegidhi remagetsi ekumaruwa, uye inozivikanwa seyakananga nzira yekuvaka substation muna 21st. zana remakore.
Hunhu hwebhokisi mhando substation
1.1.1Advanced tekinoroji uye kuchengetedzeka * Iyo bhokisi chikamu chinotora yazvino inotungamira tekinoroji uye maitiro, goko rinowanzo gadzirwa nealuminium zinc plated simbi ndiro, furemu inogadzirwa neyakajairwa midziyo yemidziyo uye maitiro ekugadzira, ane yakanaka anti-corrosion performance uye anogona chengetedza kuti haizove nengura kwemakore makumi maviri, ndiro yemukati yekuisa chisimbiso inogadzirwa nealuminium alloy gusset plate, iyo interlayer inogadzirwa nemoto uye inopisa kupisa zvinhu, bhokisi rinoiswa nemhepo inogadzirisa uye dehumidification zvishandiso, uye kushandiswa kwemidziyo isingakanganisike nemamiriro ekunze emamiriro ekunze uye kusvibiswa kwekunze, Inogona kuve nechokwadi chekushanda kwakajairika pasi penzvimbo yakaoma ye - 40 ℃~+40 ℃.Iyo yekutanga midziyo mubhokisi ndeye unit vacuum switch kabati, yakaoma-mhando transformer, yakaoma-mhando transformer, vacuum circuit breaker (spring operating mechanism) uye zvimwe zvekushandisa zvemumba.Chigadzirwa chacho hachina mhenyu zvikamu.Icho chimiro chakazara insulated, chinogona kuzadzisa zero yemagetsi kuvhunduka tsaona.Chiteshi chese chinogona kuona kushanda-pasina mafuta nekuchengetedzeka kwakanyanya.Iyo yechipiri komputa yakasanganiswa otomatiki system inogona kuona isina kutarisirwa kushanda.
1.1.2Iyo ine hungwaru dhizaini yechiteshi chese ine yakakwirira degree ye automation.Iyo yekudzivirira sisitimu inotora iyo microcomputer yakasanganiswa otomatiki mudziyo weiyo substation, iyo yakaiswa nenzira yakasarudzika, uye inogona kuona "maremote mana", anoti, telemetering, kuremesa siginecha, kure kure uye kugadzirisa kure.Imwe neimwe unit ine yakazvimirira oparesheni mabasa.Iyo relay kuchengetedza mabasa akakwana.Inogona kuseta maparamita ekushanda kure, kutonga humidity uye tembiricha mubhokisi, uye kusangana nezvinodiwa zvekushanda kusingatarisirwe.
1.1.3Munguva yefekitari yakagadziridzwa dhizaini, chero bedzi mugadziri achigadzira iyo yekutanga main wiring dhizaini uye dhizaini yemidziyo kunze kwebhokisi zvinoenderana nezvinodiwa chaizvo zveiyo substation, anogona kusarudza zvakatemwa uye mhando dzebhokisi rekushandura rakapihwa nemugadziri.Midziyo yese inoiswa uye yakagadziriswa mufekitori kamwe chete, iyo inonyatsoona kuvakwa kwefekitori kweiyo substation uye inopfupisa dhizaini nekugadzira kutenderera;Pakumisikidzwa kwesaiti kunongoda kuiswa kwebhokisi, tambo yekubatanidza pakati pemabhokisi, inobuda tambo yekubatanidza, chengetedzo yekumisikidza, bvunzo yekutyaira uye rimwe basa rinoda kutumwa.Iyo yese substation inongotora anenge 5-8 mazuva kubva pakugadzwa kusvika pakushanda, ichideredza zvakanyanya nguva yekuvaka.
1.1.4Flexible musanganiswa muodhi Iyo bhokisi remhando substation ine compact chimiro, uye bhokisi rega rega rinogadzira yakazvimirira system, iyo inoita kuti iyo yekubatanidza modhi ishanduke uye ichinje.Tinogona kutora bhokisi remhando substation, kureva, 35kV uye 10kV midziyo yakaiswa mumabhokisi ese kuti iite yakazara bhokisi mhando substation;35kV midziyo inogona zvakare kuiswa kunze, uye 10kV michina uye kutonga nekudzivirira system inogona kuiswa mukati.Iyi yekubatanidza modhi inonyanya kukodzera kuvakwazve kwezviteshi zvekare mumaruwa emagetsi grid kuvakazve, ndiko kuti, yekutanga 35kV midziyo haina kufambiswa, uye chete 10kV switch box inogona kuiswa kuti isangane nezvinodiwa zvisingatarisirwe.
1.1.5Kuchengetedza mari uye inoshanda nekukurumidza bhokisi remhando substation (35kV michina yakarongedzwa kunze uye 10kV michina yakaiswa mukati mebhokisi) inoderedza investimendi ne40% ~50% zvichienzaniswa neyakasanganiswa substation yechiyero chimwe (35kV michina yakarongedzwa kunze uye 10kV michina iri yakarongedzwa mukati meimba yepamusoro-voltage switch room uye yepakati control room).
1.1.6Muenzaniso wepamusoro unoratidza kuti nzvimbo yepasi yechiteshi inoderedzwa neanenge 70m2 nekuda kwebhokisi remhando substation pasina huwandu hwekuvaka, hunoenderana nemutemo wenyika yekuchengetedza ivhu.
1.2Kushandiswa kwebhokisi remhando substation mumaruwa emagetsi grid kuvaka (shanduko) Iyo bhokisi mhando substation mode inoshandiswa zvakanyanya mumaruwa emagetsi grid kuvaka (shanduko).Semuyenzaniso, itsva 35kV terminal substation ine main transformer inokwana 2 × 3150kVA, matatu-phase inopetwa kaviri isina excitation voltage inodzora magetsi transformer ine voltage giredhi ye35 ± 2 × 2.5％/10.5kV.
Imwe dunhu re35kV pamusoro inopinda mutsetse, 35kV vacuum load disconnector uye fuse inokurumidza zvinoshandiswa pamwe chete padivi repamusoro-voltage retransformer huru kutsiva 35kV vacuum circuit breaker, kuderedza mutengo, uye kuona kuvhura kwekubatanidza kana fuse yabatanidzwa mune imwe. chikamu uye muchikamu chekutadza kushanda.Iyo 10kV chikamu chinotora marongero ebhokisi rudzi rwemagetsi ekugovera chiteshi.Kune mitsetse mitanhatu inobuda yetambo dze10kV, imwe yacho iri reactive compensation circuit uye imwe yacho iri standby.Mabhazi e35kV ne10kV anobatanidzwa nebhazi rimwe chete pasina chikamu.Iyo substation yakaiswa pa 35kV mutsetse unouya kudivi, unokwanisa kuita 50kVA uye voltage level inosvika 35 ± 5%/0.4kV.Iyo yemagetsi yechipiri sisitimu yebhokisi mhando yekuparadzira chiteshi inotora microcomputer yakasanganiswa otomatiki system.
[$ peji] 2 Mafungiro mukugadzirwa kwebhokisi mhando substation
2.1Iyo shoma yekudzivirira moto yekudzivirira pakati peiyo main transformer nebhokisi ichasangana nezvinodiwa zveCode for Design ye35 ~ 110kV Substation, uye iyo shoma yekudzivirira moto yekudzivirira pakati pezvivakwa zvine chiyero chekudzivirira moto cheClass II uye transformer (mafuta akanyudzwa) ichave. 10m.Kune madziro ekunze akatarisana neshanduro, inopisa dielectric capacitor uye zvimwe zvigadzirwa zvemagetsi (zvichienderana nezvinodiwa firewall), kana pasina magonhi nemahwindo kana maburi mukati mehurefu hwechishandiso pamwe ne3m uye 3m pamativi ese, kureba kwakajeka pakati. rusvingo uye midziyo inogona kunge isina kuganhurirwa;Kana pasina magonhi nemahwindo akazarurwa mukati mechikamu chiri pamusoro, asi paine magonhi emoto, kureba kwemoto kwakajeka pakati pemadziro nemidziyo kuchaenzana kana kupfuura 5m.Izvo zvishoma zvekudzivisa moto chiyero chemudziyo wekugovera magetsi iGiredhi II.Iyo yekutanga sisitimu mukati mebhokisi rebhokisi mhando yemagetsi yekugovera chiteshi inotora iyo unit vacuum switch kabati chimiro.Imwe neimwe unit inotora chimiro chegonhi chakashongedzwa neakakosha aluminium profiles.Kumashure kwebay imwe neimwe ine mahwendefa ekudzivirira maviri-layer, ayo anogona kuvhura gonhi rekunze.Mubasa redu rekugadzira, iyo shoma yekudzivirira moto yekudzivirira pakati peiyo huru transformer nebhokisi inokurudzirwa kuva 10m kuti ive nechokwadi chekushanda kwakachengeteka kweiyo substation.
2.2Iyo 10kV cable outlet ichaiswa kuburikidza nemapombi esimbi nechinangwa chekunakisa.Nzvimbo yakatenderedza ye10kV bhokisi remhando yekugovera chiteshi bhokisi mune substation inowanzo gadzirwa semendi pavement, uye 10kV mutsara terminal pole inowanzoita 10m kunze kwemadziro echiteshi.Kana iyo tambo yakavigwa yakananga uye ichitungamirwa kune iyo mutsara terminal pole, ichaunza kukanganisa kukuru kune kugadzirisa.Naizvozvo, 10kV cable outlet ichaiswa kuburikidza nemapombi esimbi kufambisa kugadzirisa nekugadzirisa vashandisi.Kana 10kV line terminal pole iri kure nechiteshi, 10kV cable outlet kubva mubhokisi kusvika pakavharwa ye substation inofanira kuiswa kuburikidza nesimbi pombi.Rudzi rutsva rwe over-voltage protector inoiswa pamutsetse terminal pole pakupera kwetambo inobuda tambo kudzivirira kupfuura-voltage.
3 Mhedziso
Mumakore achangopfuura, bhokisi remhando substation ndiyo nhungamiro huru yekumaruwa magetsi grid kuvaka (shanduko) uye remangwana substation kuvaka, asi kuchine zvimwe zvinokanganisa, sediki yekuwedzera muganho weinobuda mutsara wepakati mubhokisi, diki yekuchengetedza nzvimbo, nezvimwe. .Zvisinei, inosimudzirwa zvikuru uye inoshandiswa nezvakanaka zvehupfumi uye hunoita, uye kukanganisa kwayo kuchavandudzwa nekunatswa mukuenderera mberi kwekusimudzira.
