Chigoba Chotsekereza Kuthamanga kwa Loadbreak mu Networks ya Medium Voltage

iyeChigongono cha Loadbreakndi gawo lofunikira kwambiri pa maukonde ogawa magetsi apakati, zomwe zimathandiza kuti maulumikizidwe ndi zingwe zikhale zotetezeka komanso zotetezeka pansi pa mikhalidwe yonyamula katundu. Nthawi zambiri amagwiritsidwa ntchito m'makina ogawa magetsi pansi pa nthaka ndi panja, zigongono zotsekera katundu zimapangidwa kuti zisunge umphumphu wa netiweki, kuonetsetsa kuti ntchitoyo ikugwira ntchito mosalekeza popanda kufunikira kuchepetsa mphamvu pakukonza kapena kuthetsa mavuto nthawi zonse.

The24kV Loadbreak chigongono Surge Arresterimawonjezera chitetezo chofunikira kwambiri pa maukonde amagetsi apakati poteteza ku kukwera kwamagetsi kowononga. Makampani mongaAnhuangakatswiri opanga zida zomangira chigongono zapamwamba kwambiri zomwe zimagwirizana ndiIEEE386ndiMiyezo ya IEC, kuonetsetsa kuti chitetezo, kulimba, komanso magwiridwe antchito odalirika.

1.Kodi Chigongono cha Loadbreak N'chiyani?

AChigongono cha Loadbreakndi mtundu wa cholumikizira chamagetsi champhamvu chomwe chimapangidwira ntchito zosokoneza kunyamula katundu m'ma network amagetsi apakati. Kapangidwe kake kotetezedwa kamalola kuti chilumikizidwe bwino ndikuchotsedwa ku zida zamagetsi pansi pa zovuta zonyamula katundu. Ntchito imeneyi ndi yofunika kwambiri kwa ogwiritsa ntchito makina chifukwa imalola kukonza ndi kuthetsa mavuto popanda kudula magetsi pa netiweki yonse.

Zinthu zazikulu za chigongono cha loadbreak ndi izi:

• Kutha kusokoneza katundu: Zimalola kuti zida zamagetsi zisamagwiritsidwe ntchito bwino ngakhale zitagwiritsidwa ntchito.
• Kuteteza ndi kuteteza: Zimaletsa kukhudzana mwangozi ndi magetsi okwera, kuonetsetsa kuti wogwiritsa ntchito ali otetezeka.
• Kugwirizana ndi zida zosiyanasiyana: Yoyenera ma transformer, switchgear, ndi zingwe zomwe zili mkati mwa ma network amagetsi apakatikati.

2.Zinthu Zake Za 24kV Loadbreak Elbow Surge Arrester

The24kV Loadbreak chigongono Surge ArresterIli ndi choletsa kugwedezeka kwa magetsi mkati mwa chigongono cha loadbreak, chomwe chimateteza ku kugwedezeka kwa magetsi koopsa. Mtundu uwu wapangidwa makamaka kuti ugwiritsidwe ntchito pa ma network apakati pa magetsi komwe kusinthasintha kwa magetsi kuchokera kuzinthu monga kugunda kwa mphezi ndi ntchito zosinthira kumachitika kawirikawiri.

Zinthu zofunika kwambiri za 24kV Loadbreak Elbow Surge Arrester ndi izi:

• Nyumba Yapamwamba Kwambiri ya Silicone Rubber: Imapereka chitetezo chabwino kwambiri komanso kulimba m'malo akunja.
• Chitetezo cha Kuphulika: Amachepetsa kukwera kwa magetsi, kuteteza zida monga ma transformer, switchgear, ndi zingwe.
• Kutsatira miyezo ya IEEE386 ndi IEC: Kumatsimikizira kuti zinthu zili bwino kwambiri komanso zodalirika.
• Kapangidwe Kakang'ono: Imagwirizana bwino ndi makina omwe alipo kale, ndipo imayikidwa mosavuta pa ma bushing a 200A.
• Choyikapo Choletsa Kuwonjezeka kwa 34kV: Ikupezeka ngati njira ina, yoyenera kugwiritsa ntchito ma voltage ambiri ndipo nthawi zambiri imagwiritsidwa ntchito m'makonzedwe osiyanasiyana a zida.

Mwa kuchepetsa kukwera kwa magetsi obwera komanso kupewa zochitika zoopsa za overvoltage, chogwirira ntchito cha 24kV loadbreak elbow surge arrester chimapereka chitetezo champhamvu ku zinthu zapakati pa voltage.

3.Kugwiritsa ntchito kwa 24kV Loadbreak Elbow Surge Arrester

Chotchingira cha 24kV Loadbreak Elbow Surge Arrester chimagwiritsidwa ntchito pa ma network osiyanasiyana amagetsi apakatikati ndipo chimapereka chitetezo chodalirika cha zida ku mafunde amagetsi osakhalitsa.

• Transformers: Zimateteza ma transformer windings ndi insulation ku kuwonongeka kwa voltage yanthawi yochepa.
• Zida zosinthira: Zimaletsa kuphulika kwa magetsi ndi kuwonongeka kwa dielectric chifukwa cha kukwera kwa magetsi.
• Zingwe: Amachepetsa chiopsezo cha kulephera kwa insulation mu zingwe zomwe zili ndi ma voltages ambiri osakhalitsa.

Mwa kuyang'anira ma voltage transients, loadbreak elbow surge arrester imawonjezera moyo wa zinthu zofunika izi, imachepetsa zosowa zosamalira, komanso imawonjezera kudalirika kwa netiweki.

4.Kutsatira Miyezo:IEEE386 ndi IEC

Anhuang'szomangira za chigongono cha loadbreak zimatsatiraIEEE386ndiMiyezo ya IEC, kuonetsetsa kuti akukwaniritsa zofunikira kwambiri pakugwira ntchito bwino komanso chitetezo m'makina amagetsi apakatikati.

• Miyezo ya IEEE386: Miyezo iyi imafotokoza zofunikira za zolumikizira zotetezedwa zolekanitsidwa, monga zigongono zotsekereza katundu, zomwe zimagwiritsidwa ntchito mumakina ogawa mphamvu yamagetsi apakati.
• Miyezo ya IEC: Kutsatira miyezo ya IEC kumatsimikizira kuti zinthu za Anhuang zimagwirizana ndi dziko lonse lapansi komanso kuti ndi zabwino, zomwe zimapangitsa kuti zinthuzo zikhale zoyenera misika yosiyanasiyana yapadziko lonse lapansi.

Kutsatira miyezo imeneyi kumatsimikizira ogwira ntchito pa netiweki kuti choletsa kugwedezeka kwa 24kV ndi chodalirika komanso choyenera kugwiritsidwa ntchito pamavuto.

5.Choyimitsa Kuthamanga kwa 34kV: Kukulitsa Mphamvu

Pa ma network omwe amafuna chitetezo champhamvu chamagetsi,Chojambulira cha Anhuang cha 34kV Surge Arresterimapereka chitetezo chotalikirapo. Choyika ichi chimagwiritsidwa ntchito kwambiri pakugwiritsa ntchito magetsi apakatikati ndi zida monga ma transformer, switchgear, ndi zingwe. Chimapereka chitetezo chowonjezera pa ma network omwe amagwira ntchito pafupi ndi malire a 34kV, komwe kukwera kwa magetsi kungayambitse kulephera kwakukulu kwa makina.

Choyikapo cha 34kV chimagwirizana ndi zigongono zosiyanasiyana ndipo chimapereka chitetezo chapamwamba komanso chitetezo cha surge monga chitsanzo cha 24kV, zomwe zimapangitsa kuti chikhale chotetezeka kwambiri m'makina onse a 24kV ndi 34kV.

6.Ubwino Wogwiritsa Ntchito Loadbreak Elbow Surge Arrester

Kugwiritsa ntchito chida choletsa kugwedezeka kwa chigongono cha loadbreak kumapereka zabwino zambiri pamakina amagetsi apakati:

• Zida Zowonjezereka Zokhalitsa: Mwa kuletsa kukwera kwa magetsi kufika pazigawo zobisika, choletsa kugwedezeka kwa chigongono cha loadbreak chimawonjezera nthawi yogwira ntchito ya ma transformer, switchgear, ndi zingwe.
• Chitetezo Chogwira Ntchito: Amateteza antchito mwa kuchepetsa kukwera kwa magetsi mkati mwa zida zotenthetsera, kuchepetsa chiopsezo cha kuphulika kwa arc ndi kulephera kwa zida.
• Kuchepetsa Ndalama Zogwirira Ntchito ndi Zokonza: Kuchepetsa kuwonongeka kwa magetsi ochulukirapo kumachepetsa zofunikira pakukonza ndikuchepetsa nthawi yogwira ntchito yokwera mtengo yosakonzekera.
• Kuyang'anira Mphamvu Moyenera: Imaonetsetsa kuti magetsi akugwira ntchito bwino ngakhale atakhala ndi katundu wolemera, zomwe zimathandiza kuti magetsi azigwiritsidwa ntchito bwino.

7.Chifukwa Chosankha AnhuangChigongono cha LoadbreakOgwira Ntchito Zoopsa?

Anhuangimadziwika popanga zida zomangira ma surge armour zapamwamba kwambiri, kuphatikizapo zida zomangira ma surge armour a 24kV ndi 34kV.IEEE386ndiMiyezo ya IEC, Anhuang amaonetsetsa kuti chinthu chilichonse chapangidwa kuti chipereke chitetezo chabwino komanso magwiridwe antchito abwino. Ichi ndichifukwa chake zinthu zawo zimaonekera bwino:

• Zipangizo Zapamwamba: Zomangira za Anhuang zimapangidwa ndi zinthu zolimba monga mphira wa silicone, wodziwika bwino chifukwa cha mphamvu zake zabwino kwambiri zotetezera kutentha.
• Uinjiniya Wapamwamba: Zomangira ma surge a chigongono cha loadbreak zimapangidwa ndi zipangizo zogwira ntchito bwino komanso ukadaulo kuti zikwaniritse zosowa za netiweki yamagetsi apakati.
• Kudalirika: Mwa kutsatira miyezo yokhwima, zigongono za Anhuang zimapereka chitetezo chodalirika cha mafunde, kuchepetsa zosowa zokonzera komanso kuteteza zida ku kukwera kwadzidzidzi kwa magetsi.
