Idzi data riri pamusoro rinosangana ne12kV ring main unit chikamu II earthing system technical specification yeSGCC (State Grid Corporation of China), China Southern Power Grid neJiangsu Electric Power Company, idzo dzinonyatsoenderana nekusiyana kwazvakarerekera pasi. Iine GSVR yakatevedzana 12kV tambo yekuwedzera, nzira nhatu-tambo yekubatanidza tambo uye maviri-nzira tambo ine-imwe nzira mheni yekusunga yekubatanidza musanganiswa inogoneka.
Ongorora: chikamu I: kwayakarerekera point earthing system kuburikidza nekushomeka-kupokana;
Nhanganyaya dzeCore Components Technology
Master Switch Design
a.Swichi yatenzi inoshandisa vacuum interrupter
b.Particular curve design yekuderedza simba rekugadzirisa
①Deredza kuita kwedosing
②Kuderedza basa rakawedzerwa
③Hapana imwe yekuwedzera kudzvanywa inowedzerwa kana trigger yadzoka
④Diffen the contact pressure uye kuderedza kutsika simba pakuvhura
Disconnector Design
a. Disconnectors ane matatu-chinzvimbo dhizaini inodzivirira mashandiro asiri iwo zvakakwana mudzidziso dhizaini
b. Kubata dhizaini kunobatsira kugadzira pasi, uye kukurumidza kugadzira> 4.2m/s
c. Yepamusoro-inoshanda Mubea belleville chitubu inovimbisa kugadzikana kweiyo yekubata kudzvanywa
Master Switch Mechanism
a. Mota, yekubatsira switch, kuburitsa, yekufamba switch ye master switch mechanic inobviswa uye nyore kugadzirisa
b. Two-spring precise transmission dhizaini ine basa rekuvhara
c. Otomatiki kuverenga basa rinosangana neazvino State Grid yekutenga chiyero
d. High quality quenched uye tempered simbi uye chilled simbi inoshandiswa muzvinhu zvose kutapurirana
e. Sino inotakura dhizaini yeiyo musimboti kutapurirana ine yakadzika kukanganisa-kupokana, kurodha hombe uye kudhonza kudiki kudiki.
Disconnector Mechanism Dhizaini
a. Dimbura meshini, ine matatu-nzvimbo masisitimu chitubu uye maviri akazvimirira ekushanda shafts, inodzivirira zvakanyanya misoperations zvinoenderana neiyo theoretical dhizaini.
b. Kubvisa dhizaini yekushandisa kunogona kuwedzera gadziriso yemagetsi
c. Dual clutch dhizaini inoita iyo bhuku rekushandisa uye magetsi ekushanda chinja zvakasununguka
d. Iyo shaft inobuda, ine giya yekumhanyisa dhizaini, ine yakakwira kubuda, kufambisa kwemagetsi hombe uye kukurumidza kugadzira pasi> 4.2m/s.
Kuongorora Window Dhizaini
a. Zvinoenderana neiyo optical imaging musimboti yakagamuchirwa muhwindo, huwandu hwekutarisa hunogona kunge hwakakura kunyangwe hwindo rekuona riri diki.
b. Iwindo revhu rine kuvaka-mukati chiedza zviri nyore uye zvakajeka kuona
c. Kuvhenekera ne LED kunovimbisa hupenyu hwechiedza
Dhizaini-yekununura
Dedicated pressure-relief device
Operating Bhatani Dhizaini
a. Master switch manual kushanda nebhatani dhizaini iri nyore kushanda.
b. Bhatani rinovhara rinogona kudzivirira kushandiswa zvisina kunaka uye rinogonawo kuwedzera padlock.The planetary reduction direct-current permanent magnet motor, ine diki diki uye yakagadzikana kushanda mamiriro, ane zvinoshamisa kutapurirana kushanda. Kurasikirwa kwekushanda kwesimba kunenge 3%.
Chizvarwa Chechipiri Solid Insulated Core Unit
Pamusoro negreyish chena zinc coating, yakazara ivhu uye kubata-proof dhizaini.
