Musiyano uripo pakati peDC mini circuit breaker uyeAC circuit breaker

DC (Direct Current) mini circuit breakers uye AC (Alternating Current) macircuit breakers ese ari maviri anoshandiswa kuchengetedza maseketi emagetsi kubva kune overcurrents uye mapfupi maseketi, asi ane mimwe misiyano yakakosha nekuda kwehunhu hwakasiyana hweDC neAC magetsi masisitimu.

Ikozvino Polarity:
Musiyano wakanyanya kukosha pakati peDC uye AC wedunhu mabreak kugona kwavo kubata ikozvino polarity. Mudunhu re AC, kuyerera kwazvino kunodzosera gwara nguva nenguva (kazhinji ka50 kana makumi matanhatu pasekondi, zvichienderana neiyo AC frequency).AC circuit breakersdzakagadzirirwa kukanganisa kuyerera kwazvino pa zero-kuyambuka nzvimbo, uko wave wave wave kupfuura ne zero. Kune rumwe rutivi, DC circuit breaker dzakagadzirirwa kubata unidirectional ikozvino kuyerera uye kukanganisa kuyerera kwazvino pane chaiyo voltage level.

Kukanganisa kweArc:
Mumaseketi eAC, yazvino inoyambuka zero panguva yega yega, iyo inobatsira mukudzima arc inoumba kana dunhu ravhiringwa.AC circuit breakers kutora mukana weiyi zero-yekuyambuka nzvimbo kudzima arc, zvichiita kuti kukanganiswa kuite nyore. Mumaseketi eDC, hapana chakasikwa zero-kuyambuka nzvimbo, izvo zvinoita kuti kukanganiswa kwearc kuwedzere kunetsa. DC circuit breaker dzakagadzirirwa kubata chaiwo matambudziko ekukanganiswa kwearc mumaseketi eDC.

Arc Voltage:
Iyo voltage pane mabatirwo edunhu redunhu panguva yekukanganisa arc maitiro akasiyana kune DC uye AC masisitimu. Mune AC masisitimu, iyo arc voltage inosvika zero pane yakasikwa zero-kuyambuka nzvimbo, ichibatsira mukukanganisa maitiro. Mune DC masisitimu, iyo arc voltage inoramba yakakwira, izvo zvinoita kuti kukanganiswa kuome. DC circuit breaker dzakagadzirirwa kumira uye kudzima yakakwirira arc voltages.

Kuvaka uye Dhizaini:
AC circuit breakersuye DC circuit breaker inovakwa zvakasiyana kuti igadzirise izvo zvinodiwa zveavo masisitimu. Iyo arc yekukanganisa masisitimu, zvinhu zvinoshandiswa, uye magadzirirwo ekubata anogona kusiyana pakati pe AC neDC mabreaker edunhu.

Applications:
AC circuit breakersanonyanya kushandiswa mumagetsi ekugovera masisitimu ekugara, ekutengesa, uye maindasitiri ekushandisa, uko AC simba ndiro chiyero. DC mini circuit breakers, kune rumwe rutivi, inowanzoshandiswa muDC magetsi ekugovera masisitimu, mabhangi mabhangi, masystem emagetsi anovandudzwa (sesolar nemhepo), uye mashandisirwo emuindasitiri akasarudzika panoshandiswa ikozvino.

Mukupfupisa, misiyano mikuru pakati peDC mini circuit breakers uyeAC circuit breakersvanorara mukugona kwavo kubata ikozvino polarity, arc kukanganisa maitiro, voltage zvinodiwa, kuvaka, uye maapplication avo. Izvo zvakakosha kuti ushandise iyo yakakodzera mhando yedunhu rebreaker zvichibva pane chaiyo magetsi sisitimu kuti uve nechokwadi chekuchengetedzwa kwakanaka uye kushanda kwakachengeteka.
