KunzwisisaDC MCB: Gwaro Rakazara
Munyaya dzeinjiniya yemagetsi nekugoverwa kwesimba, izwi rekuti "DC Miniature Circuit Breaker" (DC MCB) riri kuramba richinyanya kutaurwa. Sezvo kudiwa kwemagetsi anoshanda zvakanaka uye akavimbika kuri kuramba kuchikura, kunzwisisa basa reDC MCBs kwakakosha kune nyanzvi nevanofarira basa iri.
Chii chinonzi DC MCB?
DC miniature circuit breaker (MCB) mudziyo unodzivirira unodzima circuit yega kana paine overload kana short circuit yaonekwa. Kusiyana nemaAC miniature circuit breakers, anoshandiswa mumaAC system, DC miniature circuit breakers akagadzirirwa kubata maDC applications. Musiyano uyu wakakosha nekuti maitiro emagetsi muDC system akasiyana zvikuru neari muAC system, kunyanya maererano ne arc formation uye circuit breakers.
Kukosha kweDC Miniature Circuit Breakers
Kukosha kwemaDC miniature circuit breakers (MCBs) hakufanirwe kutaurwa zvakanyanya, kunyanya mukushandiswa kunosanganisira simba rinogona kushandiswazve senge solar panels nema wind turbines. Masisitimu aya anowanzo gadzira direct current, saka kushandisa DC miniature circuit breakers kwakakosha pakuona kuchengetedzeka uye kuvimbika. DC miniature circuit breakers dzinopa dziviriro ye overcurrent, zvichibatsira kudzivirira njodzi dzinogona kuitika dzakadai semoto wemagetsi uye kukuvara kwemidziyo, nokudaro zvichivandudza kuchengetedzeka kwese kwekuisa magetsi.
DC MCB inoshanda sei?
Kushanda kweDC miniature circuit breaker (MCB) kuri nyore. Kana magetsi achipfuura nepakati pedunhu akadarika mwero wakatarwa, mashandiro emukati meMCB anotangwa. Maitiro aya anowanzo kuve ne bimetallic strip kana solenoid coil inopindura kune overload current. Kana yangotangwa, MCB inovhura dunhu, ichibvisa magetsi uye ichidzivirira michina yakabatana.
Chimwe chezvinhu zvakakosha zveDC miniature circuit breaker (MCB) kugona kwayo kudzima magetsi pasina kugadzira ma arc ane njodzi. Musystem yeDC, magetsi haambopfuuri zero, izvo zvinogona kukonzera ma arc anoenderera mberi kana akasatarisirwa zvakanaka. Ma DC MCB akagadzirwa nehunyanzvi hwekubatana uye nzira dzekuderedza njodzi yeku arc uye kuona kuti arc yacho yakabatana zvakachengeteka.
Kushandiswa kweDC Miniature Circuit Breakers
MaDC miniature circuit breakers anoshandiswa mumhando dzakasiyana siyana dzekushandisa, dzinosanganisira:
1.Sisitimu yekugadzira magetsi ezuva: Mumasystem e photovoltaic, maDC MCB anodzivirira waya nezvimwe zvikamu kubva pakupisa kwakanyanya, zvichiita kuti kuiswa kwacho kuve kwakachengeteka uye kuchengetedzeka.
2. Mota dzeMagetsi: Sezvo indasitiri yemotokari ichichinja ichienda kumotokari dzemagetsi, maDC miniature circuit breakers anoita basa rakakosha mukudzivirira masisitimu emagetsi emotokari kubva mukukundikana.
3. Kutaurirana: Masisitimu mazhinji ekutaurirana anoshanda nemagetsi akananga, saka maDC miniature circuit breakers akakosha kudzivirira michina inobatwa nemagetsi kubva kumatambudziko emagetsi.
4. Mashandisirwo Emaindasitiri: Munzvimbo dzakasiyana dzemaindasitiri, maDC miniature circuit breakers anoshandiswa kuchengetedza michina nemidziyo inoshandiswa neDC.
Sarudza DC MCB chaiyo
Pakusarudza DC miniature circuit breaker, zvinhu zvinoverengeka zvinofanirwa kutariswa:
- Rated Current: Iva nechokwadi chekuti rated current yeMCB inoenderana nezvinodiwa necircuit yainoda kuchengetedza.
- Voltage yakayerwa: Voltage yakayerwa yeMCB inofanirawo kuenderana nevoltage yesystem kuti ive nechokwadi chekuti inoshanda zvakachengeteka.
- Kugona kutyora: Zvinoreva kugona kwemuchina we "miniature circuit breaker" (MCB) kukanganisa magetsi emagetsi. Kune masisitimu ane magetsi emagetsi akawandisa, kugona kutyora kwakawanda kwakakosha.
- Rudzi rweMutoro: Mitoro yakasiyana (inodzivisa, inductive, nezvimwewo) ingangoda mhando dzakasiyana dzeMCBs, saka kunzwisisa hunhu hwemutoro kwakakosha.
Muchidimbu
Muchidimbu, maDC miniature circuit breakers (MCBs) chikamu chakakosha chemagetsi emazuva ano, kunyanya mukushandiswa kunosanganisira direct current. Kugona kwawo kupa dziviriro yakavimbika ye overcurrent kwakakosha pakuona kuchengetedzeka uye kushanda zvakanaka kwemidziyo yemagetsi. Sezvo tekinoroji ichiramba ichifambira mberi, basa remaDC miniature circuit breakers rinogona kuramba richikura, zvichisimbisa kukosha kwawo mumunda weinjiniya yemagetsi. Kunzwisisa mabasa awo, mashandisirwo awo, uye zvinodiwa zvekusarudza kwakakosha kune chero ani zvake anobatanidzwa mukugadzira nekugadzirisa masisitimu emagetsi.
