Kusiyana pakati pa DC mini circuit breaker ndiAC circuit breaker

DC (Direct Current) mini circuit breakers ndi AC (Alternating Current) zonse zimagwiritsidwa ntchito kuteteza mabwalo amagetsi ku ma overcurrents ndi mafupi afupikitsa, koma ali ndi kusiyana kwakukulu chifukwa cha makhalidwe osiyana a DC ndi AC magetsi.

Polarity Yamakono:
Kusiyana kwakukulu pakati pa DC ndi AC ophwanya ma circuit ndi kuthekera kwawo kuthana ndi polarity pano. Mu dera la AC, kayendedwe kameneka kamasintha nthawi ndi nthawi (nthawi zambiri 50 kapena 60 pa sekondi iliyonse, kutengera ma frequency a AC).AC ma circuit breakersadapangidwa kuti asokoneze kuyenda kwapano pamalo odutsa ziro, pomwe mawonekedwe apano amadutsa ziro. Kumbali inayi, zida za DC zimapangidwira kuti zizitha kuyendetsa unidirectional panopa ndikusokoneza kayendedwe kameneka pamlingo wina wamagetsi.

Kusokoneza kwa Arc:
M'mabwalo a AC, mabwalo apano mwachilengedwe amawoloka ziro nthawi iliyonse, zomwe zimathandiza kuzimitsa mwachilengedwe arc yomwe imapanga dera likasokonezedwa.AC circuit breakers amapezerapo mwayi pa zero-woloka izi kuti azimitse arc, kupangitsa kuti kusokoneza kukhale kosavuta. M'mabwalo a DC, palibe malo odutsa zero, zomwe zimapangitsa kusokoneza kwa arc kukhala kovuta. Ophwanya ma circuit DC amapangidwa kuti athe kuthana ndi zovuta za kusokonezeka kwa ma arc mu mabwalo a DC.

Mphamvu ya Arc:
Magetsi pamalumikizidwe a wophwanya dera panthawi ya kusokoneza kwa arc ndi osiyana ndi machitidwe a DC ndi AC. M'makina a AC, mphamvu yamagetsi ya arc imayandikira zero pamalo achilengedwe odutsa ziro, kuthandizira kusokoneza. M'makina a DC, ma arc voltage amakhalabe okwera, zomwe zimapangitsa kusokoneza kukhala kovuta. Ma circuit breaker a DC amapangidwa kuti athe kupirira ndikuzimitsa ma arc voltages apamwamba.

Kupanga ndi Kupanga:
Zowononga ma AC ndi zowononga ma DC zimamangidwa mosiyana kuti zigwirizane ndi zofunikira za machitidwe awo. Njira zosokoneza za arc, zida zomwe zimagwiritsidwa ntchito, ndi mapangidwe olumikizirana amatha kusiyanasiyana pakati pa ma AC ndi DC ophwanya ma circuit.

Mapulogalamu:
AC ma circuit breakersamagwiritsidwa ntchito makamaka pamakina ogawa magetsi opangira nyumba, malonda, ndi mafakitale, pomwe mphamvu ya AC ndiyo muyezo. Komano, ma DC mini circuit breakers amagwiritsidwa ntchito kwambiri m'makina ogawa magetsi a DC, mabanki a mabatire, mphamvu zongowonjezwdwanso (monga solar ndi mphepo), komanso zida zapadera zamafakitale komwe kumagwiritsidwa ntchito mwachindunji.

Mwachidule, kusiyana kwakukulu pakati pa DC mini circuit breakers ndiAC ma circuit breakerszagona pakutha kuthana ndi polarity, mawonekedwe a arc kusokonezedwa, zofunikira zamagetsi, zomangamanga, ndi ntchito zawo. Ndikofunikira kugwiritsa ntchito mtundu woyenera wamagetsi oyendetsa magetsi potengera dongosolo lamagetsi kuti mutsimikizire chitetezo chokwanira komanso magwiridwe antchito otetezeka.
