Basa revacuum circuit breakers - chii chinonzi vacuum circuit breakers? Basa revacuum circuit breakers Kana iyo vacuum circuit breaker iri munzvimbo yakavharwa, kuvhara kwayo pasi kunoitwa neakakodzera insulators. Pane imwe nguva kukanganisa kwepasi kwechigarire kuchiitika munzira yakabatana kune vacuum circuit breaker, uye nzvimbo yekukanganisa pasi haina kucheneswa mushure mekufamba kwemuparadzi wedunhu, iyo vacuum gap pakuputsika kwemuparadzi wedunhu inofanirawo kuve nemhosva yekuvharisa kwevhu. bhazi remagetsi. Iyo vacuum insulation gap pakati pevanobatika inofanira kumira akasiyana ekugadzirisa voltages pasina kuparara. Naizvozvo, maitiro ekudzivirira evhavha yevacuum akave azvino ekutsvagisa zvemukati kuvandudza kuvhuvhuta voltage yekamuri yekudzimisa arc, uye kuita kuti imwechete-break vacuum yedunhu breaker ikwire kusvika padanho repamusoro. Vacuum circuit breakers ndeiyi: 1. Iyo yekubata yekuvhura kureba idiki. Iyo yekubata yekuvhura kureba ye10KV vacuum circuit breaker ingori gumi chete. Iyo yekushandisa michina ine diki kumusoro uye pasi rekushanda simba, diki sitiroko yemechini chikamu, uye hupenyu hurefu hwemuchina. 2. Iyo arc inopisa nguva ipfupi, zvisinei nehukuru hwekuchinja ikozvino, kazhinji ingori hafu yekutenderera. 3. Nekuda kweiyo diki yekupfeka mwero wekutapurirana uye conduction painopwanya ikozvino, hupenyu hwemagetsi evanobatika hwakareba, vhoriyamu yakazara yakatyoka 30-50 nguva, iyo yakatemerwa voltage inoputswa kupfuura 5000 nguva, ruzha rwakaderera. , uye inokodzera kushanda nguva zhinji. 4. Mushure mekunge arc yadzimwa, kukurumidza kugadzirisa kweiyo gap yekubata zvinhu inokurumidza, uye hunhu hwekukanganisa kwenzvimbo yepedyo yekupwanya iri nani. 5. Diki uye chiedza muhukuru, yakakodzera kuputsa capacitive mutoro ikozvino. Nekuda kwemabhenefiti ayo mazhinji, inoshandiswa zvakanyanya munhepfenyuro yekuparadzira. Mhando dzemazuva ano ndeidzi: ZN12-10, ZN28A-10, ZN65A-12, ZN12A-12, VS1, ZN30, etc. Mashandiro anoita vacuum circuit breaker "Vacuum circuit breaker" inozivikanwa nearc yekudzima svikiro uye insulating medium ye kusangana gap mushure mekudzima arc. Iine mabhenefiti ehukuru hudiki, huremu huremu, huremu huremu, etc. Inokodzera kushanda kazhinji. Nokudaro, inoshandiswa zvakanyanya mukugovera network. Nheyo yekushanda yevacuum circuit breakers haina kuoma: 1. Kuputsika kunokonzerwa nemagetsi asina kunaka: Pasi pesimba remagetsi rakasimba, kutonhora kwezviputi pamhepo yakaipa ye electrode kunowedzera nekuda kweJoule inopisa simba remhepo inobuda, uye kana tembiricha inosvika padanho rakakosha, maprotrusions anonyungudika kuti abudise chiutsi, chinotungamira kubudiriro. 2. Anode-induced breakdown: Iyo bhomba yeanode inopisa nzvimbo nekuda kweion beam inotumirwa neanode, ichibudisa kunyunguduka uye mhute, uye kuparara kwegap kunoitika. Mamiriro ekuparara kweanode ane chekuita negetsi kusimuka nekudonha index uye gap spacing. Mukuwedzera, kupikisa kwedunhu kwevacuum circuit breaker ndiyo huru pyrogen inobata kupisa, uye kupikisa kwedunhu rekamuri yekudzima arc kunowanzoita zvinopfuura 50% yekudzivirira kwedunhu kwevacuum circuit breaker. Iyo yekusangana gap redunhu redhisheni ndicho chikamu chikuru chedunhu rekudzivirira kwevacuum interrupter. Sezvo iyo yekubatanidza system yakavharirwa muvacuum interrupter, kupisa kunogadzirwa kunogona kungodzingwa kunze nekufamba uye static conducting tsvimbo. Nheyo yekuputsika yeaya mapeji ekuvhaira inoratidza kuti zvinhu zvevacuum nhanho uye pamusoro pechikuva ndizvo zvakakosha zvekudzivirira kwegeji rekutsvaira.
