High LW36 - 145 SF6 Circuit Breaker
Nhanganyaya yeChigadzirwa
Chigadzirwa chake chinoshandisa gasi reSF6 senzira yekudzima nekudzivirira arc, chinoshandisa tekinoroji yepamusoro-soro yekudzimisa arc pasi rose, uye chine mhando itsva yekushanda kwechitubu. Chine hunhu hwekushanda kwenguva refu kwemagetsi, simba shoma rekushanda, ruzha rushoma, uye kuvimbika kwakanyanya. Chimiro chayo chiri nyore, chidiki muhukuru, uye ine nguva refu yekugadzirisa. Ndicho chigadzirwa chakavimbika zvikuru munzvimbo dzakakwirira kana masisitimu emagetsi e132KV, uye chinogona kutsiva zvigadzirwa zvinotengeswa kunze kwenyika zverudzi rumwe chete.
Muchina wekupwanya dunhu unoshandisa chimiro che "porcelain pillar" che "three-phase porcelain pillar single break structure", chine "spring" inoshandiswa ne "phase" ye "three phases" dzakarongwa pakati uye dzakabatana ne "three phases", zvichikonzera chitarisiko chitsva uye chakanaka. Muchina wekupwanya dunhu unoshandisa "SF6 gas" se "insulation" uye "arc extinguishing medium". Munguva yekushanda, "three poles" dze "circuit breaker" dzakabatana ne "SF6 gas", uye "pointer type density relay" inoshandiswa kutarisa kufambira mberi kwe "pressure" uye "density". Nekuda kwekushandisa "self powered arc extinguishing principle" uye dhizaini yakagadziriswa mu "circuit breaker motion system", kushanda zvakanaka kwe "mechanical efficiency" kwakagadziridzwa uye simba rekushanda raderedzwa zvakanyanya; Kushanda zvakanaka kwe "break" uye hupenyu hwemagetsi hurefu.
Chigadziko chekuisa nekutsigira zvakagadzirwa nemaplate esimbi emhando yepamusoro akakombama ese, uye kugadziriswa kwepamusoro pechinhu chose kwakagadzikwa nesimbi inopisa. Zvese zvinosungirirwa pachena zvakagadzirwa nezvinhu zvine simba guru uye zvakagadzikwa nesimbi inopisa kana kushandisa zvikamu zvesimbi isingatsvi. Goko rekunze rebhokisi remuchina rakagadzirwa nezvinhu zvisina tsvina, saka chigadzirwa ichi chinodzivirira ngura zvakanyanya; Kuvimbika kwakanyanya kwemuchina, chinokwanisa kushanda nguva nenguva;
