Mukhoza kudziwa zinthu zatsopano zilizonse zomwe zimafalitsidwa pano, ndikuona kukula kwathu ndi luso lathu.
Tsiku: 07-29-2025
Popeza nthawi zonse timagwiritsa ntchito magetsi apansi panthaka, kufunika kwa kugawa kodalirika, kotetezeka komanso kosinthasintha kukuwonjezeka tsiku ndi tsiku. Izi zimafuna kukhazikitsa kokonzedwa bwino kwa zolumikizira za chigongono kuti zilumikizane bwino ndikuchotsa ma circuits amphamvu.
Zolumikizira izi zimalumikiza zingwe zapansi panthaka ku zingwe zofewa kutsogolo pa ma transformer okhazikika, zomwe zimaonetsetsa kuti pali kulumikizana kotetezeka komanso kodalirika pakati pa zingwe zamagetsi ndi ma transformer.
Kotero, kodi kwenikweni ndi chiyaniCholumikizira cha chigongono cha LoabreakKodi imagwira ntchito bwanji?
Tiyeni tiyankhe mafunso awa, pakati pa ena ambiri, m'nkhaniyi.
Chigongono cha mabuleki olemera ndi cholumikizira cholekanitsidwa, chotetezedwa, chomwe chimagwiritsidwa ntchito m'makina ambiri amagetsi otsika mpaka apakati posinthira mphamvu yamagetsi. Zolumikizira za chigongono cha mabuleki olemera zimagwiritsidwa ntchito kulumikiza zingwe zapansi panthaka, zapakati pamagetsi ku ma transformer, switchgear ndi zida zina.
Zolumikizira izi zimapereka kulumikizana kwa makina ndi magetsi kotetezedwa mokwanira komanso kotha kumizidwa m'madzi, ndipo zimapangidwa kuti zipange kapena kuswa kulumikizana komwe kumayikidwa. Zambiri mwa izo zimayesedwa pamakina a 15 kV, 25 kV ndi 35 kV.
Kuti zitsimikizire kuti zimasinthana komanso kuti zigwire ntchito bwino pansi pa katundu komanso m'njira zosiyanasiyana zamagetsi, zigongono zambiri zochotsera katundu zimakwaniritsa miyezo yamakampani mongaIEEE 386.
Zigongono za buledi wolemera zimathandiza kulumikizidwa ndi kulumikizananso pogwiritsa ntchito zida zomatira. Nazi zina mwa zinthu zake zofunika:
Iyi ndiyo ntchito yawo yaikulu, chifukwa amatha kusokoneza ndikulumikiza kulumikizana kwa magetsi okwana 200 A, pomwe akugawa kapena kupatula zida zosiyanasiyana popanda kuchepetsa mphamvu ya dongosolo lonse.
Nsonga ya electrode ya ceramic imadutsa kupitirira chigongono ndipo imathandiza kuzimitsa arc yomwe imapangidwa polekanitsa kulumikizana komwe kuli pansi pa katundu.
Ogwiritsa ntchito amatha kugwiritsa ntchito zida zotenthetsera zomwe zimateteza kutentha (zitoliro zotentha) kuti atulutse ndikuyika chigongono. Apa, njira yopangira masika imagwiritsidwa ntchito kuchepetsa kupsinjika kwa magetsi ndi kuwonongeka, pomwe akulamulira kuyambika kwa arc.
Malo oyesera mphamvu amaphatikizidwa mu zigongono zolepheretsa kunyamula katundu kuti atsimikizire ngati kulumikizana kuli bwino isanayambe komanso itatha kulekanitsidwa. Malo oyesera mphamvu awa salumikizidwa ndi kondakitala wamkulu.
Zonsezi zimagwira ntchito mogwirizana kuti zilole zolumikizira zoletsa katundu kulumikizana ndikuchotsa kulumikizana kwamoyo pomwe zikusunga chitetezo cha wogwiritsa ntchito ndi makina.
Zolumikizira zoletsa katundu zimapezeka m'mitundu yosiyanasiyana kutengera kalasi ya voltage, malo ogwiritsira ntchito, ndi kasinthidwe. Tiyeni tikambirane za mitundu ina yomwe imagwiritsidwa ntchito kwambiri:
Ma elbows oletsa kunyamula katundu amabwera m'mitundu yosiyanasiyana ya ma voltage, ena mwa iwo ndi awa:
15kV:Amapangidwira ma circuits a mphamvu yofika 15 kV, ndi mphamvu yopitilira ya ma Ampere 200. Zolumikizira za chigongono za 15 kV izi zimatetezedwa mokwanira, zimamizidwa ndipo nthawi zina zimakhala ndi zolumikizira za bimetal.
25kV:Izi Zigongono zopumira katundu za 25 kvZimayesedwa pamakina mpaka 24 kV, nthawi zambiri pa 250 A continuous current yokhala ndi mphamvu yochulukirapo ya 300 A kwa maola 8. Zimathandizira zingwe zoteteza za XLPE kapena EPR zokhala ndi magawo ozungulira a conductor kuyambira ~25–120 mm². Zimagwiritsidwa ntchito kwambiri m'makina amagetsi amakono ndipo zimapereka njira yotetezeka yolumikizira/kuchotsa ma circuits ambiri.
35kV:Ngakhale 25Kv katundu wosweka zigongonoKawirikawiri amagwiritsidwa ntchito, 35 kV imagwiritsidwanso ntchito pazinthu zinazake. Amatha kupirira mphamvu yopitilira mpaka 200 Amperes ndi voltage rating kapena mpaka 35 kV. Kuti azitha kuyendetsa bwino magetsi akuluakuluwa, ali ndi peroxide cured EPDM insulation ndi semiconducting shield, coppertop compression connector, tin-plated copper probe yokhala ndi arc-follower tip, komanso malo oyesera capacitive optional.
Zolumikizira zoletsa katundu zimabwera m'njira zosiyanasiyana kuti zigwirizane ndi mapulogalamu osiyanasiyana
Chigongono chokhazikika cha katundu:Izi zimagwiritsidwa ntchito kulumikiza chingwe chimodzi ku chipangizo chimodzi (monga transformer, switchgear). Zimagwiritsa ntchito nsonga zotulukira za ceramic probe kuti zithandizire ntchito zogwira ntchito.
Chigongono cha mtundu wa Junction:Amatchedwanso kuti multi-way kapena tee configuration elbows. Amalola nthambi polumikiza zingwe zingapo pamodzi mkati mwa nyumba imodzi yotetezedwa. Ma configuration ofanana ndi awa: 2-point, 3-point, ndi 4-point junction elbows omwe amagwiritsidwa ntchito m'magawo ovuta ogawa.
Ndi malo oyesera a capacitive:Zigongono zolekanitsa katunduzi zimakhala ndi sensa yopangidwa, yothandiza posonyeza mphamvu ya magetsi ya dera (nthawi zambiri pafupifupi 10–12% ya mphamvu ya magetsi ya gawo mpaka pansi). Mbali imeneyi imalola kutsimikizira mphamvu ya magetsi popanda kupatsa mphamvu cholumikizira mwachindunji.
Popanda malo oyesera:Izi ndizoyenera kuyika komwe kuyesa kwa magetsi kumachitika kwina, zigongono izi sizingapereke mayankho amagetsi omwe amafika pansi nthawi yomweyo.
Ngakhale kuti zigongono zambiri zothyola katundu zimakhala ndi kapangidwe kokhoza kumizidwa m'madzi, zina zimakhalanso ndi mapangidwe osapsa ndi dzimbiri.
Mapangidwe Otha Kumira
Mapangidwe oviikidwa m'madzi awa amatha kugwira ntchito bwino pansi pa madzi kapena m'nthaka yodzaza ngati atagwirizanitsidwa bwino ndi ma bushings kapena ma plugs oyenera. Mwachitsanzo, Anhuang'sZigongono zopumira katundu za 25 kVkupereka kulumikizana kotha kumizidwa kwathunthu komanso kolekanitsidwa.
Mapangidwe Osawononga
Zigongono zina zothyola katundu zimagwiritsidwa ntchito m'malo owononga, monga m'madera a m'mphepete mwa nyanja kapena m'mafakitale a mankhwala. Zimapereka maulumikizidwe olekanitsidwa bwino komanso otetezedwa ndi chitsulo chosapanga dzimbiri ndi zida za rabara za EPDM zomwe zimapangidwa kuti zisawonongeke ndi chilengedwe m'malo ovuta.
Nazi zina mwa ntchito zenizeni za zigongono zothyola katundu:
Kugawa mphamvu pansi pa nthaka
Zigongono zochotsera katundu zimagwiritsidwa ntchito kwambiri polumikiza zingwe zapansi panthaka zapakati pamagetsi ndi ma transformer, switchgear, ndi zida zina popanda kusokoneza ntchito.
Ma transformer ndi switchgear oikidwa pa Pad
Zimathandiza kuti ntchito yotetezeka komanso yotentha igwire ntchito polumikiza kapena kuchotsa zida pamakina amoyo monga ma transformer okhazikika pa pad ndi switchgear.
Kukhazikitsa mafakitale, zida zogwirira ntchito ndi zamalonda
Zigongono zochotsera katundu zimagwiritsidwa ntchito m'malo osungiramo zinthu zamagetsi, makina amagetsi amafakitale, ndi nyumba zamabizinesi komwe kumafunika kugawa magawo ndi kusinthana kwa katundu wamoyo.
Mafamu a mphamvu zamagetsi a mphepo, dzuwa ndi mphamvu zongowonjezwdwanso
Izi ndi zabwino kwambiri pokhazikitsa zinthu zongowonjezedwanso (monga minda ya mphepo ndi dzuwa) komwe ntchito zosinthasintha komanso zogwira ntchito zimathandiza kuchepetsa nthawi yogwira ntchito panthawi yokonza.
Migodi ndi machitidwe a sitima
Amagwiritsidwa ntchito m'malo ovuta monga ntchito za migodi ndi makina amagetsi a sitima kapena a metro kuti asunge mphamvu nthawi zonse pamene akulekanitsa magawo kuti agwiritsidwe ntchito.
Zolumikizira za chigongono zolekanitsa katundu ndizofunikira kwambiri mukafuna kupatula mbali zina za makina amagetsi apansi panthaka omwe ali ndi mphamvu yapakati komanso yotsika. Zimapereka njira yodalirika komanso yotetezeka yokonzera mbali zina za ma circuits popanda kusokoneza magetsi onse.
Ngati mukufuna kugulaZolumikizira za chigongono za 25 kV zotsegula katunduKuti mugwiritse ntchito, muyenera kuwona mitundu yosiyanasiyana ya Anhuangzigongono zosweka katundu.
