Molded case circuit breaker: muchengeti wepakati wekugoverwa kwesimba remagetsi mashoma

1. Kuziva Kwakakosha: "Nzira Yekuchengetedza" ye Nyaya Yakaumbwa Maputsi edunhu

Ma "molded case circuit breakers" akapihwa mazita ekushandisa mapurasitiki ekugadzira ane simba guru (akadai se "glass fiber reinforced polyamide") se "outer casing". Ane zvakanakira zvekudzivirira kupisa, huremu hushoma, uye kuiswa kunochinjika. Ndiwo "standard configuration" yekugoverwa kwesimba remagetsi mashoma. Huremu hwayo hunoita basa rekuti "three-in-one": inoshanda se "on-off switch" mumamiriro ekushanda akajairwa, inononoka kudzima magetsi kana paine overload, uye inodzima fault current muma milliseconds panguva ye short-circuit kudzivirira kukuvara kwemidziyo uye njodzi dzemoto.

Kushanda kwayo nemazvo kunoenderana nekushanda pamwe chete kwezvikamu zvishanu zvepakati: goko rakasungirirwa ne ultrasonic, rine dziviriro ye IP30-IP54, uye zvimwe zvikamu zvine mahwindo akajeka; ma contacts esirivha alloy ane dhizaini ye "kutanga kugadzira uye ipapo kupwanyika", tichifunga nezve conductivity uye arc resistance; grid yesimbi ine layer yakawanda inodzima arc nekukurumidza; nzira yekuchengetedza simba ine mabar mana inoita kuti kuvhura nekuvhara kugadzikane; sisitimu yekugumburwa yakakamurwa kuita thermomagnetic type (bimetal + electromagnet) uye electronic type (MCU precise temperature control) kuti ienderane nezvinodiwa nemamiriro akasiyana.

2. Gwaro rekusarudza: kugadzirisa kuchengetedzeka ndiyo musimboti mukuru

Sarudzo yacho inofanira kutevedzera misimboti mina mikuru uye kutarisa pamaparamita mashanu makuru: ratio yemagetsi inopetwa ka1.1-1.3 kupfuura kukosha kwakaverengerwa kwemutoro; nhanho yemagetsi inoenderana nemutengo chaiwo wetambo (yakajairika AC 400V/690V, Dc 250V/750V); kugona kutyora kunochinjika kunoenderana nehurongwa hwemagetsi hupfupi; huwandu hwemapango hunosarudzwa zvichienderana nerudzi rwehurongwa; hunhu hwekugumburwa hunoenderana nemutoro (hunhu hweD hwakakodzera mamota, hunhu hweK hwakakodzera masemiconductor).

Zviitiko zvakakosha zvinoda kusarudzwa kwakanangana: macircuit breaker akakosha emagetsi emagetsi emagetsi emagetsi (photovoltaic DC systems); kushandiswa munzvimbo dzakakwirira (dzinopfuura mamita 2,000) dzine simba shoma; uye mamodheru ekudzivirira ngura munzvimbo dzinopisa. Panguva imwe chete, gadzirisa kuiswa, waya uye kugadzirisa kuti zvisakanganisa mashandiro ekudzivirira.

3. Tarisiro Yeramangwana: Kuvakwa Kwezvakatipoteredza Uye Kwakangwara Kwenzvimbo Itsva

Inotungamirirwa ne "dual carbon" uye digitalization, indasitiri iyi ichavaka ecosystem itsva ine hungwaru uye zvakatipoteredza. Mitemo inokurudzira kuvandudzwa kwekushandisa simba zvakanaka uye mitemo yekudzivirira zvakatipoteredza, kubatanidzwa kwakadzama kwehungwaru uye tekinoroji ine kabhoni shoma, uye kuwedzera kwemiganhu yekushandisa tekinoroji inoganhurira kuyerera kwemvura.

Makambani anotungamira ari kukurumidza kushandura "kugadzira + sevhisi", uye mabhizinesi madiki nepakati ari kutarisa munzvimbo dzinokosha. Nekuvandudzwa kwesimba idzva neIndustry 4.0, macase circuit breakers achaita basa guru mukuchengetedzwa kwesimba uye kugadzirisa mashandiro esimba, uye indasitiri ichavandudza kuita tekinoroji uye masevhisi akawanda.
