High-Performance LW36-40.5 Circuit Breaker yeZvikumbiro zveHigh-Voltage
Muenzaniso uye zvinoreva
Pfupiso
Chinopwanya magetsi cheLW36 - 40.5 chakagadzirwa zvakanaka kuti chishandiswe pakuchinja ma capacitor bank, zvichiratidza kuti chinochinjika zvakanaka mu capacitor discharge scenarios mukati me 750kV ne 550kV substations. Ichishandisa musimboti wesimba rayo, inoita basa rakanaka: ine current pfupi inogadzira magetsi inosvika 50kA uye current yakaderedzwa ye capacitor banks inosvika 3150A, parameter performance yayo iri pakati petior yepamusoro muindasitiri. Ingave iri kukanganiswa kwema motors ane voltage yakawanda, mashandiro ema reactors akabatana nebhazi, kuchinja ma transformers, kana mamiriro akaomarara ekushanda akadai sekuchaja line uye small inductive current switching (kusanganisira capacitive current switching, shunt reactor switching, uye transformer no - load current switching), LW36 - 40.5 circuit breaker inoabata zviri nyore, ichivimbisa kushanda kwesimba remagetsi nekushanda kwayo kwakavimbika. Iine tangi reSF6 inflatable pamwe chete ne short - stroke arc - extinguishing mechanism, inotsigira kuiswa nekukurumidza kwemhando dzakagadziriswa nedzinogona kubviswa pasina kuputsa arc - extinguishing chamber. Izvi zvinobvumira kuiswa zvakananga muzviteshi zvemagetsi zviripo, zvichideredza zvakanyanya nguva yekuisa uye mari yevashandi, uye zvichipa simba guru mukufambira mberi kwakanaka kwemapurojekiti emagetsi.
Nzira yekushandisa yechitubu yakagadzirwa nekuchinjika uye nehungwaru, ichitsigira nzira dzakasiyana-siyana dzinosanganisira remote control, local operation, uye manual emergency operation. Izvi zvinogutsa zvizere zvinodiwa zvakasiyana-siyana zvekushandisa mumamiriro akasiyana-siyana, zvichiita kuti mashandiro ave nyore uye akangwara.
