Ntchito ya ophwanya ma circuit

Pamene dongosolo mapulogalamu amalephera, wamba zolakwa zigawo kuteteza kaimidwe, ndi wosweka dera kwenikweni ntchito vuto wamba kukana ulendo, ndi dera wosweka moyandikana wa substation adzateteza ulendo malinga ndi wamba zolakwika zigawo.Ngati zinthu sizikulola, njira yachitetezo itha kugwiritsidwanso ntchito kupanga ulendo wakutali wodutsa nthawi imodzi.Njira yopangira ma waya imatchedwa kuti circuit breaker common fault protection.
Nthawi zambiri, pambuyo pa kusuntha kwa zigawo zamakono, magulu a 2 a zolumikizira zothamanga amatengedwa ndikulumikizidwa mndandanda ndi zolumikizira zachitetezo chakunja, ndiyeno chitetezo chodziwika bwino chimayendetsedwa panjira.
Kodi woyendetsa dera amachita chiyani?
Zowononga ma circuit zimagwiritsidwa ntchito makamaka m'ma motors, zosinthira malo akulu ndi malo ogawa omwe nthawi zambiri amadula katundu.Wowononga dera ali ndi ntchito yophwanya chitetezo cha ngozi, ndipo amagwirizana ndi zotetezera zosiyanasiyana zotetezera kuteteza zipangizo zamagetsi kapena njira.
Wowononga dera nthawi zambiri amagwiritsidwa ntchito ngati gawo la mphamvu yowunikira yotsika kwambiri, ndipo amatha kulumikiza dera;wowononga dera amakhalanso ndi ntchito zingapo monga katundu ndi chitetezo chafupipafupi, koma pakakhala vuto ndi katundu womwe uli pansipa, uyenera kusungidwa.ntchito, ndipo voteji yosweka ya wophwanyira dera ndiyosakwanira.
Masiku ano pali chotchinga chamagetsi chogwira ntchito ndi chitetezo, chomwe chimaphatikiza ntchito za wowononga wamba komanso cholumikizira chamagetsi.Wowononga dera wogwira ntchito wokhala ndi chitetezo atha kugwiritsidwanso ntchito ngati chosinthira chodzipatula chokhala ndi thupi la munthu.M'malo mwake, ma switch odzipatula amagetsi okwera kwambiri nthawi zambiri sangathe kuyendetsedwa ndi katundu, koma zotchingira zozungulira zimakhala ndi ntchito zoteteza monga vuto laling'ono, kuteteza katundu, komanso chitetezo chamagetsi.
Limafotokoza mwatsatanetsatane mfundo ntchito ophwanya dera
Mtundu Woyambira: Chida chosavuta chotetezera dera ndi fusesi.Fuse ndi chingwe chopyapyala, chokhala ndi sheath yoteteza, yomwe imalumikizidwa ndi dera.Deralo litazimitsidwa, zonse zam'mlengalenga ziyenera kudutsa fusesi, ndipo fusejiyo imakhala yofanana ndi yomwe ili ndi mfundo zina pagawo lomwelo.Fuse iyi imapangidwa kuti ikhale yotseguka pamene kutentha kwapakati kufika pamlingo wina.Ma fuse owonongeka amathanso kuyambitsa njira zowongolera kuti madzi ochulukirapo asawononge mawaya anyumba.Vuto la fusesi ndiloti limakhala ndi mphamvu imodzi yokha.Nthawi zonse fuseyo ikawonongeka, iyenera kusinthidwa ndi yatsopano.Wowononga dera amatha kugwira ntchito yofanana ndi fusesi, koma angagwiritsidwenso ntchito nthawi zambiri.Malingana ngati zamakono zikufika pamlingo wowopsa, nthawi yomweyo zidzatsogolera njira.
Mfundo yofunikira: Waya wamoyo ndi waya wosalowerera m'derali amalumikizidwa mbali zonse ziwiri za switch yamagetsi.Pamene batani ili mu chikhalidwe cholumikizidwa, zamakono zimatulutsidwa kuchokera ku zipangizo zotsika pansi, motsatizana zikuyenda kudzera mu electromagnet, cholumikizira cha AC cholumikizira, cholumikizira cha AC, ndipo pamapeto pake chimatulutsidwa kuchokera pazida zapamwamba.Magetsi amatha kukhala maginito amagetsi.Mphamvu ya maginito yopangidwa ndi electromagnet imawonjezeka ndi panopa.Ngati panopa kuchepetsedwa, mphamvu ya maginito idzafowokanso.Pomwepo ikalumphira pachiwopsezo, mphamvu yamagetsi yamagetsi imapanga mphamvu ya maginito yokwanira kusuntha ndodo yachitsulo yolumikizidwa ndi kulumikizana kosinthira mphamvu.Izi zidzachititsa foni AC contactor kuti skew ndi kusiya malo amodzi deta AC contactor, kutsegula dera.Pakali panonso imasokonezedwa.Zingwe zachitsulo zosavala zimapangidwa motsatira mfundo yomweyo.Mosiyana English, izo siziyenera kupereka maginito mphamvu kinetic mphamvu, koma amalola zitsulo Mzere kupinda pansi mkulu panopa, amene amayendetsa kugwirizana.Ena ophwanya madera amasuntha chosinthira mphamvu malinga ndi kuchuluka kwa zophulika.Yapano ikapitilira mulingo wina, imayatsa zida zoyaka ndi kuphulika, kenako ndikukankhira ndodo ya piston kukanikizira switch.
Kuwongoleredwa: Oyendetsa madera otsogola kwambiri amasankha kusiya zida zosavuta zamagetsi ndikugwiritsa ntchito zamagetsi (makampani a semiconductor) kuti azindikire kuchuluka komwe kulipo.Ground Fault Interrupter (GFCI) Uwu ndi mtundu watsopano wophwanya dera.Zowonongeka izi sizimangoteteza kuwonongeka kwa mawaya a nyumba, komanso kuteteza anthu ku electrocution.
Mfundo yokwezera: GFCI ipitilizabe kuzindikira mawaya omwe salowerera ndale komanso mawaya amoyo muderali.Zonse zikayenda bwino, mafunde a mabwalo awiriwa ayenera kukhala ofanana ndendende.Kusalowerera ndale kukakhala kokhazikika nthawi yomweyo (mwachitsanzo, anthu ena mwangozi akhudza osalowerera ndale), zomwe zikuchitika muzandale zidzayamba mwadzidzidzi, koma osalowerera ndale sadzatero.GFCI ikazindikira chinthu choterocho, nthawi yomweyo imadula chigawocho kuti chiteteze electrocution.Ma GFCI sayenera kudikirira mpaka pano akwera kufika paziwopsezo, motero kuyankha kwawo kumathamanga kwambiri kuposa ophwanya wamba.
