Technical Parameter
Me sunan abubuwan da ke ciki da GIS equipment?
Saboda insuliya mai kyau, arc extinguishing performance da stability performance na SF6 gas, GIS equipment tana da abubuwan da ke ciki kamar small footprint, strong arc extinguishing ability da high reliability, amma insuliya na SF6 gas yana kasance da uniformity na electric field, kuma yana iya haɓaka insulation abnormalities idan akwai tips ko foreign objects a cikin GIS.
GIS equipment tana da fully enclosed structure, wanda tana ba da abubuwan da ke ciki kamar internal components without environmental interference, long maintenance cycle, low maintenance workload, da low electromagnetic interference, amma tana da rashin overhaul work masu karfi da detection methods masu karfi, kuma idan closed structure yana cika da damage da external environment, zai iya haɓaka water ingress da air leakage.
Yadda na musamman yana cikin wannan tushen bayanin da aka bani "gabatarwa mai sauƙi a fannoni na izalawa": ① Daga baya da GIS mai sauƙi gas ta haka, HGIS yana haɗa da busbar mai sauƙi hawa, wanda ya ɗaukar muhimmancinta ga yanayin sauƙin gas. Yana da muhimmanci a fannoni da aka fi sani da ingantaccen kanan mutum amma yana bukata tsariyar ayyukan mafi muhimmanci; ② Daga baya da AIS mai sauƙi hawa ta haka, masu ayyukan muhimman kwakwalwa na HGIS suna yi sauƙin gas, wanda ya haifar da tsarin shi. Yana da muhimmanci a fannoni da kuma kanan mutum (misali: substation mai birnin da offshore platforms) kuma yana ɗaukar tushen gida zuwa ayyukan mafi muhimmanci.
Siffar da Zafi:
A cikin zafi, elektronu a molekulai gas na SF₆ suna kama da wani yawan abin da ba a nukil. Amma, saboda inganci a kan siffar da zafi na molekulai gas na SF₆, ya fi shi gaba da sarrafa harkokin elektronu daga fuskantar zuwa mazaunuka, wanda yake taka da tsarin zafi mai kyau. A wurare IEE-Business (Gas-Insulated Switchgear), an samu zafi ne tun daga fuskantar tsari, kyakkyawa, da kuma siffar da zafi na gas na SF₆. Wannan yana taimaka waɗanda ake iya haɓaka da zafi mai kyau da ƙasa a kan bayanan aiki da wasu tsohon kaya, da kuma a kan bayanan aiki da wasu tsohon kaya.
Idan an yi aiki a cikin zafi na ƙananan, babu elektronu masu ƙwarewa a cikin gas suna samu karfi daga siffar da zafi, amma wannan karfin ba ya fi shi gaba da mutuwar da gas na molekulai su. Wannan yana taimaka waɗanda ake iya daidaita zafi mai kyau.
Na gaba da kyauka cikakkiyar karamin gasar SF6, kyauka shiga karamin hawa da kuma kyauka ainihi, samanar GIS na da muhimmanci masu tafukar fushi, kyauka shiga karamin hawa da kuma inganci, amma kyauka cikakkiyar karamin gasar SF6 yana kasance da darajar da take da aiki a kan karamin hawa, kuma zai iya canzawa cikakkiyar abin da ake da tsirrai ko abubuwa masu wani a kan GIS.
Samanar GIS ta yi aiki a kan sauran yanayi, wanda ya ba da muhimmanci masu tafukar fushi baki daya, tafukar inganci mai zurfi, tafukar inganci mai kadan, tafukar karamin hawa mai kadan, kuma tafukar karshen karamin hawa mai kadan, kuma kuna da abubuwa masu gaba-gaban da ake da su kamar aiki mai zurfi da ake yi a kan yanayin kawo karfi, kuma hanyar neman da ke da aiki mai zurfi, kuma idan yanayin kawo karfi an yi nasara da karshen jirgin sama da karamin hawa, zai iya ba da muhimmiyar abubuwa masu gaba-gaban kamar ƙarin ruwa da karamin hawa.
