Vacuum interrupter yekuremerwa break switch (205A)
Tsanangudzo pfupi yechigadzirwa:
Mune mamwe mamiriro ezvinhu, vacuum circuit breaker inogona kumanikidza yazvino mudunhu kusvika zero pamberi pezvakasikwa zero (uye kudzoreredzwa kwezvino) munharaunda inochinja-chinja.Kana interrupter oparesheni nguva isingafadzi maererano neAC-voltage waveform (kana arc yadzimwa asi macontacts achiri kufamba uye ionization haisati yaparara mune inovhiringidza), voltage inogona kudarika gap's stand voltage.Izvi zvinogona kubatidzazve arc, zvichikonzeresa kukurumidza kupera kwemhepo. Zvinogoneka kudzikisa nhanho iripo panguva iyo kucheka kunoitika nekusarudza chinhu chinobatika chinopa mhute yesimbi yakakwana kubvumira yazvino kuti isvike pakukosha kwakanyanya kana zero kukosha. , asi izvi hazviwanzoitwa sezvo zvinokanganisa simba re dielectric.
Mazuva ano, nekudzikira kwazvino kutema, vacuum circuit breakers haizokonzeresa kuwandisa kunogona kuderedza insulation kubva kumidziyo yakatenderedza.
Vacuum arc yekudzimisa kamuri, inozivikanwawo sevacuum switch chubhu, ndiyo yakakosha chikamu chemagetsi switch.Basa rayo guru nderokuita kuti dunhu rikurumidze kudzima arc uye kudzvinyirira ikozvino mushure mekucheka magetsi kuburikidza neakanakisa vacuum insulation muchubhu, kuitira kudzivirira tsaona uye tsaona.
Iwo macontacts anotakura dunhu razvino kana akavharwa, achigadzira materminals earc kana akavhurwa.Iwo akagadzirwa nemhando dzakasiyana-siyana, zvichienderana nekushandiswa kwevacuum interrupter uye dhizaini yehupenyu hurefu hwekusangana, kukurumidza kudzoreredza kwevoltage inomira rating, uye kutonga kwekuwedzeredza nekuda kwekutema kwazvino.
Vacuum interrupter ine zvidziviriro zvakatenderedza mabatirwo uye kumagumo eanovhiringidza, kudzivirira chero chinhu chekubata chinoputiswa panguva yearc kubva mukunyungudika mukati mevhayumu envelopu.Izvi zvinoderedza simba rekudzivirira rehamvuropu, zvichizopedzisira zvaita kuti chivharidzirwe kana chakavhurika.Iyo nhoo inobatsirawo kudzora chimiro chekugovera kwemagetsi-munda mukati memuvhiringidzi, zvichibatsira kune yakakwira yakavhurika-yedunhu voltage rating.Inobatsira kutora rimwe resimba rinogadzirwa muarc, richiwedzera kukanganisa kwechigadzirwa.
