Maumbirwo ema vacuum circuit breakers

chivhariso chemagetsi chinoshandiswa kudzora, kuchengetedza uye kuparadzanisa macircuit emagetsi. Kusiyana nemacircuit breakers echinyakare anoshandiswa nemafuta kana gasi senzira yekudzima arc, macircuit breakers anoshandisa vacuum arc extinguishing chamber senzira yekudzima arc inogadzirwa panguva yekupwanya circuit. Chimwe chezvakanakira zvikuru zve vacuum circuit breaker kugona kwayo kuvhura circuit nekukurumidza, kuderedza kukuvara uye kudzivirira tsaona dzemagetsi.

Maumbirwo emuchina wekupwanya dunhu wevacuum anowanzo sanganisira zvinhu zvikuru zvitatu: imba yekudzima arc, mashandiro ekushanda uye chinhu chekudzora. Interrupter ine macontact maviri esimbi akaparadzaniswa mukati meimba yekupwanya. Kana circuit breaker yavhurwa, vacuum medium ine simba re dielectric inoita kuti macontacts avharwe. Zvisinei, kana paine dambudziko uye circuit breaker ichifanira kugumburwa, macontacts acho anosangana, zvichitanga maitiro ekudzima arc.

Muchina wekushanda une basa rekuvhura nekuvhara circuit breaker pasi pemamiriro ezvinhu akajairwa uye asina kunaka. Muchina uyu unoshandisa matekinoroji akasiyana-siyana akadai sesimba rakachengetwa (masprings) kana ma electromagnetic actuators kuti agadzire simba remakanika rinodiwa. Kune rumwe rutivi, zvinhu zvekudzora zvinovimbisa kubatana kwakakodzera uye kuenderana kwezvishandiso zvekushanda. Zvinosanganisira maswichi ekubatsira, ma relay uye ma timers uye zvinoita mabasa akadai se trip coil activation, kuona zvikanganiso uye kubvisa zvikanganiso. Aya ma interlocking mechanisms anovimbisa kushanda kwakachengeteka uye kwakavimbika kwe vacuum circuit breaker.

Muchidimbu, ma "vacuum circuit breakers" chikamu chakakosha chemagetsi, zvichivimbisa kuchengetedzwa kwemidziyo nevashandi kubva kumatambudziko emagetsi. Maumbirwo e "vacuum circuit breaker" ane "arc extinguishing chamber", "operating mechanism" uye "control element", izvo zvinobatana kuti zvibudirire pakuputsa ma "circuit breaker" uye "arc extinguishes". Kunzwisisa zvikamu zvayo nemabasa ayo kunobatsira mainjiniya nematekiniki kuita sarudzo dzakarongeka pavanenge vachigadzira, vachiisa, uye vachichengetedza masisitimu emagetsi mudzimba, mumabhizinesi, uye mumaindasitiri. Nekushandisa mabhenefiti akawanda ema "vacuum circuit breakers", tinogona kuve nechokwadi chekuti zvivakwa zvemagetsi zvakachengeteka uye zvakavimbika pasi rose.
