Musiyano pakati peDC fuse Holder uye Miniature Circuit Breaker

TheDC fuse inobatainowanzoiswa munharaunda uye inoshandiswa kuitira kuchengetedza kuchengetedzwa kwedunhu panguva yekushanda kwechikamu chakakosha chemagetsi.Mafiyuzi eDC anodzivirira anogona kupa dziviriro yenguva pfupi, uye anoshandiswa zvakanyanya mumagetsi ekugovera masisitimu, kudzora masisitimu, nezvimwewo. Iyo fiyuzi inonyanya kuita basa mukudzivirira-pfupi-redunhu kudzivirira uye yakakomba overload kudzivirira.

Kazhinji,DC miniature circuit breakersinogona kushandiswa kugovera simba remagetsi kana kutanga asynchronous motors zvisingaite, uye zvakare kuchengetedza tambo dzemagetsi nemamotor.Kana iyo DC yedunhu breaker ikasangana nekuremerwa kwakanyanya, pfupi dunhu, kana undervoltage kukanganisa panguva yekushanda, inozodzima dunhu.Basa remutsigiri wedunhu rakafanana nekusanganiswa kwefuse switch uye overheating relay.

Iyo yakajairika poindi yeDC fuse uye mini yedunhu breaker: inogona kugura dunhu zvakanaka kana dunhu ratadza, saka zvinogona kutaurwa kuti ese ari maviri midziyo yekudzivirira yedunhu, inonyanya kushandiswa kuchengetedza inotyora wedunhu kubva pakuremerwa uye kupfupi dunhu.

Chii Basa reDC Fuse Holder uye Mini Circuit Breaker?

Iyo miganho yeDC mini circuit breakers haina kujeka.Iyo chiyero chekushandisa inowanzo kupatsanurwa kuita yakakwira-voltage matunhu mabreak uye yakaderera-voltage circuit breaker.Kazhinji, isu tinowanzo kudaidza mavoltages pamusoro pe3KV seyakakwira-voltage circuit breakers, uye low-voltage circuit breakers inonziwo otomatiki switch.Icho chigadziro chemagetsi chisina kungoita shanduko yemanyorero, asi zvakare ine otomatiki yekudzivirira michina yekurasikirwa kwevoltage, undervoltage, overload uye pfupi-circuit.DC circuit breakers yakakamurwawo kuita universal circuit breakers uye molded case circuit breakers.Kazhinji, hapana chikonzero chekushandura zvikamu uye zvikamu mushure mekunge chikanganiso chaputsika, uye chave chichishandiswa zvakanyanya.

Nepo iyo DC fuse inobata chiri chidziviriro chazvino chinochengetedza midziyo yemagetsi kuburikidza neazvino.Mushure mokunge ikozvino inodarika kukosha kwakatarwa kweimwe nguva yenguva, kupisa kunokonzerwa nefuse pachayo kunokurudzira kunyunguduka kwekunyunguduka, nokudaro kuputsa dunhu.Mafiyuzi eDC anowanzo shandiswa zvakanyanya mune yakaderera-voltage magetsi ekugovera masisitimu uye ekudzora masisitimu nemidziyo yemagetsi.Sedziviriro yepfupi-yedunhu uye pamusoro-ikozvino, ndeimwe yeanonyanya kushandiswa ekudzivirira emidziyo.

Nokudaro, DC circuit breaker inogona kutsiva fuse, chero bedzi iyo yakatemerwa kushanda ikozvino pakati pefuse uye yedunhu inoputika yakafanana neyakatemerwa kutyora ikozvino.Asi kana muparadzi wedunhu akashandiswa sefiyuzi, ishoma kudarika here?

Ndeupi Musiyano Pakati peDC fuse Holder uye Mini Circuit Breaker?

Kufanana pakati peDC fuse holders uye macircuit breaker ndewekuti vanogona kuona dziviriro pfupi-yedunhu.Nheyo yefuse ndeye: kushandisa ikozvino kuyerera kuburikidza nekondukita kuchapisa mutyairi, mushure mekusvika pakunyungudika kwemutyairi, kondakita anonyungudika.Nokudaro, dunhu rinogona kubviswa kuchengetedza midziyo yemagetsi nemitsetse kubva pakupiswa.Iko kuunganidzwa kwekupisa, saka kudzivirira kwekuremerwa kunogonawo kuitika, kana kunyungudika kwapiswa, kunyungudika kunofanirwa kutsiviwa.Apo mutoro wemagetsi munharaunda uri pedyo nemutoro wefuse inoshandiswa kwenguva yakareba, fuse ichapisa zvishoma nezvishoma kusvikira yasanganiswa.Kusanganiswa kwefuse ndiko kuguma kwechiito chekubatana kwemazuva ano uye nguva, iyo inobata basa rekudzivirira mutsara.Zvinoraswa.

Iyo DC yedunhu inotyora inogona zvakare kuona iyo pfupi dunhu uye yakawandisa kudzivirira kwemutsara, asi musimboti wakasiyana.Iyo inoziva kuchengetedzwa kwedunhu redunhu kuburikidza neazvino pasi magineti maitiro (electromagnetic tripper), uye inoziva kudzivirira kwekuremerwa kuburikidza nekupisa kwezvino.Apo ikozvino munharaunda inongoerekana yawedzera uye inodarika mutoro wemutsigiri wedunhu, muvharidzi wedunhu achangovhura.Icho chidziviriro chekuwedzera pakarepo ikozvino yedunhu, sekuti kana iyo inodonha yakakura, pfupi pfupi, kana pakarepo ikozvino yakakura.Mushure mokunge chikonzero chacho chawanikwa, chinogona kuchinjwa uye kuenderera mberi kushandiswa.

Kunyange kana mabasa uye mabasa eDC circuit breaker uye fuse zvakafanana, kuchine misiyano yakawanda, yakadai semisiyano yekudzivirira nzira, kumhanya kwekushanda, nguva dzekushandisa, uye nheyo dzekushanda.Musiyano uripo pakati pefuse uye wedunhu breaker ndewekuti:

1. Musiyano wenzira yekudzivirira: iyo DC fuse inobata nzira yekudzivirira inotora fomu refuse.Mushure mekunge chiitiko chinokanganisa chabviswa, fuse inoda kuchinjwa kuti idzorere magetsi, saka zvakanyanya kunetsa kuchengetedza.Iyo nzira yekudzivirira yeDC wedunhu breaker inotora fomu rekufambisa.Mushure mekunge kukanganisa kwabviswa, iyo yakajairika magetsi inogona kudzoserwa chete kuburikidza nekuvhara chiito, saka kuchengetedza uye kudzoreredza kuchave kuri nyore kupfuura fuse.

2. Musiyano mukumhanya kwechiito: iyo fuse chiito kumhanya kweiyo DC fuse inogona kusvika kune microsecond (μs) nhanho, izvo zvinoreva kuti kumhanya kwayo kunomhanya zvakanyanya kupfuura iyo yedunhu breaker.Kugona uku kunowanzova kwakakodzera kukurumidza kucheka-kure zvinodiwa Kuiswa uye kushandisa pasi pemamiriro ezvinhu.Sipidhi yekugumburisa yedunhu rinotyora iri mumamilliseconds (ms).Inogona kuonekwa kuti inononoka kudarika fuse, saka yakakodzera chete kune dzimwe nguva apo kukurumidza kucheka hakusi kwakanyanya.

3. Musiyano wenhamba yenguva dzekushandiswa: iyo fuse yeDC inofanira kuchinjwa mushure mokunge kuchengetedzwa kwemhosva kwaitwa kamwe chete uye kunyunguduka kwakaputika, uye DC circuit breaker inogona kushandiswa zvakare mumatambudziko akawanda.Zvisinei, kubva pakuona kwemaitiro ekuputsa kwedunhu, fuse ichave yakasimba kudarika mhepo inoputika, uye panguva imwechete yakanyatsojeka.Mumamiriro ezvinhu akajairika, muparadzi wedunhu akaiswa mumugwagwa webazi, uye fuse yakaiswa mumugwagwa mukuru muzviitiko zvakawanda kuti iite basa rekudzivirira kwechipiri.

4. Musiyano wekushanda musimboti: Nheyo yekushanda yefyuzi yeDC inonyanya kuenderana nekupisa kwezvino.Apo ikozvino inodarika kukosha kwakagadziriswa (zvakasiyana-siyana zvigadziriso zvefuse zvakare zvakasiyana), fuse yemukati ichaputika kuputsa dunhu nekudzivirira Midziyo haipiswi nepamusoro-soro.Nepo kune akawanda marudzi eDC mabreaker uye misimboti yavo yemaitiro akasiyana.Kazhinji, rwendo coil excitation inokonzerwa nekunyanyisa ikozvino kuita kuti muparadzi wedunhu aite nhanho yekugumburwa.Ehezve, muparadzi wedunhu haangogone kungoita otomatiki otomatiki, asiwo Manually kudzora kuvhura uye kuvhara zviito zvemupunzi wedunhu.

Mune dzimwe nguva dzakakosha, kune akajeka ane hukama anosungirwa mirau iyo inofanirwa kushandisa DC fuse, senge elevator kudzora kuchengetedzwa, saka DC circuit breaker haigone kutsiva zvachose fuse.Uyezve, iyo ipfupi-yedunhu nguva yedunhu redunhu thyristor module ipfupi kwazvo.Muchiitiko ichi, kumhanya kwekufambisa kwedunhu redunhu hakugone kusangana nezvinodiwa zvenguva pfupi, saka iyo fusing kugona kwefuse yave kuzivikanwa zvakare.Iyo DC fuse yakashandiswa zvakanyanya mukuvaka nyoro yekutanga, frequency kutendeuka uye mamwe masisitimu ekugovera.
