Motar juyawa

Akwai nau'ikan injinan lantarki masu juyawa da yawa.Dangane da ayyukansu, an raba su zuwa janareta da injina.Dangane da yanayin wutar lantarki, an raba su zuwa injin DC da injin AC.Dangane da tsarin su, an raba su zuwa injinan aiki tare da injunan asynchronous.Dangane da adadin matakai, ana iya raba injinan asynchronous zuwa injin asynchronous na zamani guda uku da injin asynchronous lokaci-lokaci;bisa ga nau'ikan rotor daban-daban, an raba su zuwa keji da nau'ikan rotor masu rauni.Daga cikin su, kejin asynchronous motors mai sauƙaƙan tsari da kera su.Sauƙaƙawa, ƙarancin farashi, aiki mai dogaro, mafi yawan amfani da injina daban-daban, buƙatu mafi girma.Kariyar walƙiya na injinan lantarki masu jujjuyawar (janeneta, kyamarori masu daidaitawa, manyan injina, da dai sauransu) ya fi na taranfoma da wahala, kuma yawan haɗarin walƙiya ya fi na tasfoma.Wannan shi ne saboda na'urar lantarki mai jujjuyawar tana da wasu halaye daban-daban da na'ura mai ba da hanya tsakanin hanyoyin sadarwa ta fuskar tsarin rufewa, aiki da haɗin kai.
(1) Daga cikin na'urorin lantarki na matakin ƙarfin lantarki iri ɗaya, yunƙurin jure yanayin ƙarfin lantarki na insulation na injin lantarki mai juyawa shine mafi ƙanƙanta.
Dalili kuwa shine: ①Motar tana da juzu'in jujjuyawa mai saurin sauri, don haka yana iya amfani da matsakaici mai ƙarfi kawai, kuma ba zai iya amfani da ruwa mai ƙarfi (man mai canza launin) matsakaicin haɗin gwiwa kamar injin wuta: yayin aikin masana'anta, matsakaicin matsakaici yana da sauƙin lalacewa. , kuma rufin shine Voids ko gibba suna iya faruwa, don haka zubar da ruwa yana da wuyar faruwa a lokacin aiki, wanda zai haifar da lalacewa;② Yanayin aiki na rufin mota sune mafi tsanani, batun haɗuwa da tasirin zafi, girgizar injiniya, danshi a cikin iska, gurbatawa, damuwa na lantarki, da dai sauransu, Saurin tsufa ya fi sauri;③Filayen lantarki na tsarin insulation na motar yana da ingantacciyar daidaituwa, kuma tasirin tasirin sa yana kusa da 1. Ƙarfin wutar lantarki a ƙarƙashin overvoltage shine mafi raunin haɗin gwiwa.Don haka, ƙimar ƙarfin lantarki da matakin rufewa na injin ba zai iya zama babba ba.
(2) Ragowar wutar lantarki na mai kama walƙiya da aka yi amfani da shi don kare motar da ke jujjuyawa yana da kusanci sosai da ƙarfin jurewar wutar lantarki na motar, kuma gefen rufin ƙanƙara ne.
Misali, yunƙurin jurewar ƙarfin lantarki na janareta shine kawai 25% zuwa 30% sama da ƙimar ƙarfin lantarki na 3kA na jan ƙarfe na zinc oxide, kuma gefen na'urar busa maganadisu ya yi ƙarami, kuma gefen rufin zai kasance. kasa yayin da janareta ke gudana.Saboda haka, bai isa ba don kare motar ta hanyar kama walƙiya.Dole ne a kiyaye shi ta hanyar haɗin capacitors, reactors, da sassan na USB.
(3) Rufin tsaka-tsaki yana buƙatar cewa tsayin igiyoyin kutsawa yana da iyaka.
Saboda karfin jujjuyawar motsin motsi yana da karami kuma yana katsewa, igiyar wutar lantarki na iya yaduwa ne kawai tare da madubin jujjuyawar bayan ya shiga cikin injin, kuma tsawon kowane jujjuyawar iskar ya fi girma fiye da na iskar wutar lantarki. , Yin aiki akan jujjuyai biyu masu maƙwabtaka Ƙarfin wutar lantarki ya yi daidai da tsayin igiyar kutsawa.Don kare rufin tsaka-tsakin motar, tsayin igiyoyin kutsawa dole ne a iyakance sosai.
A takaice, abubuwan da ake buƙata na kariyar walƙiya na injinan lantarki masu juyawa suna da girma da wahala.Wajibi ne a yi la'akari da cikakken la'akari da bukatun kariya na babban abin rufewa, tsaka-tsakin tsaka-tsakin tsaka-tsaki da tsaka-tsakin tsaka-tsakin tsaka-tsakin iska.
