Kunzwisisa DC Circuit Breakers: Zvikamu Zvakakosha zveKuchengetedzwa kweMagetsi
Munyaya yeinjiniya yemagetsi, kukosha kwekudzivirira macircuit hakufanirwe kupfuudzwa zvakanyanya. Pakati pemidziyo yakawanda yekudzivirira, maDC circuit breaker ndiwo akakosha pakudzivirira masisitimu emagetsi anotungamira magetsi (DC). Chinyorwa chino chichaongorora mashandiro, mhando, mashandisirwo, uye mabhenefiti emaDC circuit breaker uye chicharatidza kukosha kwawo mumagetsi emazuva ano.
Chii chinonziDC circuit breaker?
DC circuit breaker mudziyo unodzivirira unoshandiswa kumisa direct current mucircuit kana paine overload kana malfunction. Kusiyana neAC circuit breakers, dzakagadzirirwa kubata alternating current, DC circuit breakers dzakagadzirirwa kugadzirisa matambudziko akasiyana anokonzerwa nedirect current. Izvi zvinosanganisira kudiwa kwe effective arc disappear, sezvo DC circuit dzisingapfuure zero, izvo zvinoita kuti kumisa current kuve kwakaoma.
MaDC circuit breakers anoshanda sei?
Nheyo yekushanda kweDC circuit breaker ndeyekuona mamiriro asina kujairika mucircuit. Kana paine overload kana short circuit yaonekwa, circuit breaker inovhura otomatiki contacts, nokudaro ichibvisa current. Izvi zvinodzivirira kukuvara kwezvikamu zvemagetsi, zvinoderedza njodzi yemoto, uye zvinovimbisa kuchengetedzeka kwemidziyo nevashandi.
Kune mhando mbiri huru dzeDC circuit breakers: mechanical neelectronic. Mechanical DC circuit breakers dzinoshandisa michina yepanyama yakaita semasprings nema levers kupwanya circuit. Kusiyana neizvi, electronic DC circuit breakers dzinoshandisa masensa nema microcontrollers kuona zvikanganiso uye kutanga maitiro ekupwanya. Rudzi rumwe nerumwe rune zvarwakanakira, nemechanical circuit breakers dziri nyore uye dzakasimba, nepo electronic circuit breakers dzichipa kunyatsojeka uye nguva yekupindura nekukurumidza.
Kushandiswa kwemaDC circuit breakers
MaDC circuit breaker anoshandiswa zvakanyanya mumabasa akasiyana-siyana, kunyanya mumagetsi anodzokororwa, mota dzemagetsi, uye otomatiki yeindasitiri. Semuenzaniso, mumagetsi ezuva, maDC circuit breaker anodzivirira ma inverter nezvimwe zvikamu kubva pakuwandisa kwesimba, nokudaro zvichiita kuti system yese ishande zvakachengeteka. Saizvozvowo, mumotokari dzemagetsi, macircuit breaker aya anoita basa rakakosha mukudzivirira mabhatiri nemagetsi kubva pakukanganisa, nokudaro achivandudza kuchengetedzeka kwemotokari yese uye kuvimbika kwayo.
Munzvimbo dzemaindasitiri, maDC circuit breaker anoshandiswa mumabasa anoshandisa maDC motors nemadrives. Anopa dziviriro inodiwa ye overload uye short-circuit, zvichiita kuti muchina ushande zvakanaka uye kuderedza nguva yekushanda inokonzerwa nekutadza kwemagetsi.
Mabhenefiti eDC circuit breakers
Pane zvakanakira zvakawanda zvekushandisa maDC circuit breakers. Chekutanga, anodzivirira zvikanganiso zvemagetsi, izvo zvakakosha pakuchengetedza kusimba kwemagetsi. Chechipiri, anokurumidza kudzima kufamba kwemagetsi, achideredza njodzi yekukuvadzwa kwemidziyo uye achideredza mukana wekubvira kwemoto. Pamusoro pezvo, maDC circuit breakers madiki uye anoshanda zvakanaka, zvichiita kuti akwanise kushandiswa zvakasiyana-siyana kubva mudzimba kusvika kumaindasitiri.
Pamusoro pezvo, kufambira mberi kwetekinoroji kwakatungamira mukugadzirwa kwema "smart DC circuit breakers" anogona kutaurirana nezvimwe zvishandiso musystem yemagetsi. Kugona uku kunogonesa kutarisa uye kuongorora panguva chaiyo, zvichigonesa kugadzirisa nekukurumidza uye kuvandudza kuchengetedzeka kwese kwezvivakwa zvemagetsi.
Muchidimbu
Muchidimbu, maDC circuit breakers chinhu chakakosha mumunda weinjiniya yemagetsi, zvichipa dziviriro yakakosha kumaDC systems. Kugona kwavo kuona nekukanganisa zvikanganiso kunoita kuti pave nekuchengetedzeka uye kuvimbika mumabasa akasiyana-siyana, kubva kumasystem esimba rinogona kushandiswazve kusvika kumotokari dzemagetsi. Sezvo tekinoroji ichiramba ichifambira mberi, basa reDC circuit breakers richawedzera kukosha, zvichiratidza kudiwa kwekuvandudzwa nekuvandudzwa munzvimbo iyi yakakosha yekuchengetedza magetsi.
