I-CB/CWB/CWW 6-35KV 200-3150A Umugqa wesiteshi samandla sangaphandle esinamandla kagesi aphezulu uhlobo lwe-ceramic wall bushing
Incazelo Yomkhiqizo
I-Wall casing ibizwa nangokuthi i-wall casing, i-wall casing, i-casing engangeni manzi, ipayipi elishumekwe odongeni, kanye ne-casing engangeni manzi ihlukaniswe yaba i-casing eqinile engangeni manzi kanye ne-flexible engangenwa amanzi.I-AC wall bushing esetshenziselwa ukuqhutshwa kukagesi ibizwa ngokuthi i-AC wall bushing, engahlukaniswa ibe i-dry capacitive AC wall bushing kanye ne-porcelain insulated AC wall bushing, okubizwa ngokuthi i-silicone rubber bushing kanye ne-porcelain bushing ngokulandelanayo.
Izihlahla zobumba ezidlula odongeni zilungele iziteshi zikagesi, iziteshi ezincane, izinsiza zokusabalalisa amandla kanye nezinto zikagesi ezinamandla kagesi ezinamandla kagesi we-AC voltage ngaphansi kuka-35kV.Zisetshenziswa njenge-insulation kanye nokusekelwa kwezingxenye eziqhutshwayo ezidlula ezindongeni noma kwezinye izinto eziphansi.Ama-bushings afanele izinga lokushisa elizungezile -40℃+40℃.
Ama-wall-through porcelain bushings ahlukaniswa abe ngaphandle nangaphakathi ngokuya ngendawo yokufaka.Ngokwesakhiwo, ihlukaniswe yaba uhlobo lwenduku yomhlahlandlela kanye nohlobo lwebha yebhasi.Ngokusho kwezinto zomqhubi ezisetshenzisiwe, ihlukaniswe yaba yi-aluminium conductor kanye ne-copper conductor.Ngokusho kwendawo yokufaka, ihlukaniswe ngohlobo olujwayelekile kanye nohlobo olumelana nokungcola.
Ukukhetha ama-wall bushings
1. Thayipha bese uthayipha ukukhetha
Ngokusho kwendawo yokufaka, uhlobo lwasendlini kanye nohlobo lwangaphandle lungakhethwa.Ngokusho kwesicelo, izindonga zodonga ezinama-conductor kanye
ibhasi .Amadivayisi okusabalalisa amandla asendlini ngokuvamile asebenzisa i-aluminium conductor wall bushings.
2. I-voltage elinganisiwe ikhethiwe
ngokuya ngemibandela yokuthi i-voltage elinganiselwe ye-wall bushing akufanele ibe ngaphansi kwe-voltage elinganiselwe yegridi yamandla lapho itholakala khona.Uma kuneqhwa neqhwa, i-3~20kV odongeni yangaphandle kufanele ikhethe umkhiqizo onamandla kagesi aphezulu.Ku-3-6kV, imikhiqizo enamazinga amabili akhuphuka kagesi ingasetshenziswa.
3. Isilinganiso samanje ukukhetha
i-wall bushing nge-conductor, futhi i-current yayo elinganiselwe ngeke ibe ngaphansi komthamo oqhubekayo osebenzayo wesifunda.I-busbar yohlobo lwe-wall bushing ngokwayo ayinakho abaqhubi, ngakho-ke ayikho inkinga ngokukhethwa kwamanje okulinganiselwe, kodwa ubukhulu bebhasi elivunyelwe ukudlula efasiteleni kufanele buhlolwe.

Imingcele yezobuchwepheshe yomkhiqizo
Izici zomkhiqizo nendawo yokusetshenziswa
1. Ngayinye inezinzuzo zosayizi omncane, isisindo esincane, kanye nezinto zokuhamba ezikahle.
2. I-insulator ngayinye eyinhlanganisela inamandla aphezulu emishini, isakhiwo esithembekile, ukusebenza okuzinzile, kanye nemajini yokuphepha ephezulu ukuze kuqinisekiswe ukusebenza okuphephile kwesekethe.
3. Isivikelo sikagesi esiyinhlanganisela ngasinye sisebenza kahle kakhulu, i-hydrophobicity enhle nokuhamba, nokumelana namabala.
4. Inekhono elihle le-flashover yokulwa nokungcola, futhi ingasebenza ngokuphepha ezindaweni ezingcoliswe kakhulu ngaphandle kokuhlanza ngesandla, igwema ukulinganisa iphoyinti elinguziro.
5. Yonke i-A insulator eyinhlanganisela inokumelana ne-asidi, ukumelana ne-alkali, ukumelana nokuguga kokushisa kanye nokumelana namandla, ukusebenza kahle kokuvala uphawu, futhi ingaqinisekisa umswakama wokushisa nokunye.
6. I-Anti-brittleness, amandla okuzamazama komhlaba, azikho izingozi zokuphuka.
Izimo zemvelo:
1) I-casing yasendlini
Izinga lokushisa le-ambient alikho ngaphezu kuka+40 ℃ futhi alikho ngaphansi kuka -40 ℃
Ukuphakama akudluli ku-1000 m
Inani elimaphakathi lanyanga zonke lomswakama ohlobene alikho ngaphezu kuka-90%
Umoya ozungezile ngeke ungabi nakonakala noma ukungcola okusobala okufana negesi evuthayo nomhwamuko wamanzi.
Akukho ukudlidliza okunodlame okuvamile
2) I-casing yangaphandle
Izinga lokushisa le-ambient akufanele libe ngaphezu kuka+40 ℃ futhi lingabi ngaphansi kuka -40 ℃;
Ukuphakama akufanele kudlule i-1000 m;
Isivinini somoya asidluli ku-34m/s
Ngokusho kwe-GB/T5582, izinga lokungcoliswa komoya lendawo yokusetshenziswa komkhiqizo lihlukaniswe ngamaleveli amane: I, II, III kanye ne-IV;
Akukho ukudlidliza okunodlame okuvamile
Ukuhlukaniswa nokufakwa komkhiqizo
Ukusetshenziswa nokuhlukaniswa:
I-casing yakhiwe izingxenye ze-porcelain, izesekeli zensimbi, ama-flanges akhuphukayo kanye nemigoqo yokuhambisa (izinduku).
Izindonga ze-porcelain bushings zisetshenziselwa imishini yokusabalalisa amandla kanye nezinto zikagesi ezinamandla kakhulu eziteshini zikagesi nasezindaweni ezingaphansi, ukuze izintambo zidlule kuma-partitions aphansi, izindonga noma izinsimbi zikagesi ezivalekile, futhi zisekele izingxenye eziqhutshwayo ukuze ziwavale emhlabathini noma emhlabathini. indawo ebiyelwe.
Ama-porcelain bushings angahlukaniswa abe odongeni lwangaphakathi nangaphandle-nge-porcelain bushings ngokuya ngendawo esetshenziswayo.Ngokwamakhondakta ahlukene adlula enkabeni yayo, ingahlukaniswa ibe ibha yebhasi ngokusebenzisa udonga lwe-porcelain bushing, ikhondakta yethusi ngokusebenzisa i-wall porcelain bushing kanye ne-aluminium conductor through-wall porcelain bushing.
Lapho umqhubi wethusi exhunywe ngokuqondile kubha yebhasi, ukugqwala kwe-galvanic kulula ukwenzeka, futhi ukuphakama kwezinga lokushisa kwendawo yokuxhumana kuphezulu kakhulu, okuzokwenza ukuthi ukuhlangana kushise futhi kuthinte impilo yemishini.Ngakho-ke, amajoyinti okuguqula i-copper-aluminium kufanele asetshenziswe, kodwa kuzoletha izinkinga ekwakhiweni kwesayithi.I-casing ingaxazulula izinkinga ezingenhla.
Izindonga ze-porcelain zangaphakathi nangaphandle ziqoqwe kusuka ezingxenyeni ze-porcelain, izinduku ze-conductive, izesekeli zensimbi emikhawulweni yomibili kanye nama-flanges akhuphukayo.I-busbar wall-th through porcelain bushing ihlanganiswa kusuka ezingxenyeni ze-porcelain, izesekeli zensimbi emikhawulweni yomibili, i-busbar splint kanye ne-flange ekhuphukayo (i-busbar splint ivame ukulungiswa ngumsebenzisi ngokuya ngobukhulu bebhasi).
Imiyalo yokufakwa nokusetshenziswa:
1. I- through-wall porcelain bushing ifanele impahla yokusabalalisa yeziteshi zikagesi neziteshi ezincane lapho amandla alinganiselwe we-AC amandla e-AC engaphansi kuka-40.5kv, izinga lokushisa elizungezile lendawo yokufaka lingu -40°C~+40°C, futhi ukuphakama akudluli ku-1000m.
2. Izihlahla zodonga zasendlini azifanele izindawo lapho i-koqweqwe lwawo, izesekeli zensimbi kanye ne-cement adhesive ye-bushing zonakaliswe noma zanele ukunciphisa ukusebenza kukagesi we-bushing.
3. Uma ukukhishwa kwengxenye kwenzeka ngesikhathi sokusebenza kodonga lwe-porcelain bushing, hlola ukuthi kukhona yini ukuchithwa kwengxenye yongqimba olufuthwe nge-aluminium endaweni evulekile noma engaphakathi ye-porcelain bushing, futhi uma kunjalo, thatha izinyathelo zokulinganisa ingcindezi yesikhashana isikhathi.
4. Imbobo yodonga yokufaka i-busbar through-wall porcelain bushing kufanele ivulwe ngokuvumelana nobukhulu obukhulu bokuqiniswa kwayo kwe-flange.
