Kuki moteri igomba guhitamo 50HZ AC?|

Kunyeganyega kwa moteri nimwe mubintu bigezweho bya moteri.None, uzi impamvu ibikoresho byamashanyarazi nka moteri ikoresha 50Hz ihinduranya amashanyarazi aho gukoresha 60Hz?

Ibihugu bimwe na bimwe kwisi, nku Bwongereza na Amerika, bikoresha 60Hz bisimburana, kubera ko bikoresha sisitemu ya cumi, ibyo inyenyeri 12, amasaha 12, amashiringi 12 bingana na pound 1 nibindi.Nyuma ibihugu byafashe sisitemu icumi, inshuro rero ni 50Hz.

None se kuki duhitamo 50Hz AC aho kuba 5Hz cyangwa 400Hz?

Byagenda bite niba inshuro ziri hasi?

Umuyoboro muto cyane ni 0, ari DC.Kugirango hagaragazwe ko Tesla ihinduranya akaga ari akaga, Edison yakoresheje umuyagankuba kugirango amashanyarazi atora inyamaswa nto.Niba inzovu zifatwa nk'inyamaswa nto… Mu buryo bushyize mu gaciro, mu bunini bungana, umubiri w'umuntu urashobora kwihanganira umuyaga utaziguye igihe kirenze Igihe cyo guhangana n'umuyaga uhindagurika bifitanye isano na fibrillation ya ventricular, ni ukuvuga ko guhinduranya umuyaga ari bibi cyane.

Cute Dickson nawe yatsinzwe na Tesla amaherezo, AC yatsinze DC ninyungu zo guhindura byoroshye urwego rwa voltage.Mugihe cyingufu zimwe zohereza, kongera voltage bizagabanya umuyoboro wogukwirakwiza, kandi ingufu zikoreshwa kumurongo nazo zizagabanuka.Ikindi kibazo cyo kwanduza DC nuko bigoye gucika, kandi iki kibazo kiracyari ikibazo kugeza ubu.Ikibazo cyo kwanduza DC nikimwe nikibatsi kibaho mugihe amashanyarazi yakuwe mugihe gisanzwe.Iyo ikigezweho kigeze kurwego runaka, ikibatsi ntigishobora kuzimwa.Tuyita “arc”.

Kubisimburanya byubu, ikigezweho kizahindura icyerekezo, harigihe rero igihe cyarenze zeru.Dukoresheje iki gihe gito cyigihe, turashobora guca kumurongo ugezweho ukoresheje ibikoresho bizimya arc.Ariko icyerekezo cya DC cyubu ntikizahinduka.Hatariho iyi zero-yambukiranya, byatugora cyane kuzimya arc.

Ni ikihe kibi kirimo AC nkeya?

Icyambere, ikibazo cyo gukora neza

Transformator yishingikiriza kumihindagurikire yumurima wa magneti kuruhande rwibanze kugirango yumve intambwe-hejuru cyangwa intambwe-y-uruhande rwa kabiri.Buhoro buhoro inshuro yumurongo wa magneti uhinduka, intege nke zinjira.Urubanza rukabije ni DC, kandi nta induction na gato, bityo inshuro ni nke cyane.

Icya kabiri, ikibazo cyamashanyarazi yibikoresho byamashanyarazi

Kurugero, umuvuduko wa moteri yimodoka ninshuro zayo, nka 500 rpm iyo idakora, 3000 rpm iyo yihuta kandi ihindagurika, naho imirongo yahinduwe ni 8.3Hz na 50Hz.Ibi birerekana ko uko umuvuduko mwinshi, niko imbaraga za moteri nini.

Muri ubwo buryo bumwe, kuri frequence imwe, moteri nini, niko imbaraga zisohoka, niyo mpamvu moteri ya mazutu iba nini kuruta lisansi, kandi moteri nini kandi ikomeye ya mazutu irashobora gutwara ibinyabiziga biremereye nkamakamyo ya bisi.

Muri ubwo buryo bumwe, moteri (cyangwa imashini zose zizunguruka) isaba ubunini buto nimbaraga nini zisohoka.Hariho inzira imwe gusa - yo kongera umuvuduko, niyo mpamvu inshuro yumurongo uhinduranya udashobora kuba muke cyane, kuko dukeneye ubunini buto ariko imbaraga nyinshi.moteri y'amashanyarazi.

Kimwe nukuri kuri inverter yumuyaga, igenzura ibisohoka imbaraga zumuyaga uhindura imashini uhindura inshuro yumurongo uhinduranya.Muri make, imbaraga ninshuro bifitanye isano neza murwego runaka.

Byagenda bite niba inshuro ari nyinshi?Kurugero, bite nka 400Hz?

Hano haribibazo bibiri, kimwe nuko gutakaza imirongo nibikoresho byiyongera, ikindi nuko generator izunguruka vuba.

Reka tubanze tuvuge kubyerekeye igihombo.Imirongo yohereza, ibikoresho byo gusimbuza, nibikoresho byamashanyarazi byose bifite reaction.Imyitwarire iringaniye na frequence.munsi.

Kugeza ubu, reaction yumurongo wa 50Hz wohereza ni hafi 0.4 ohm, ikubye inshuro 10 kurwanya.Niba yiyongereye kuri 400Hz, reaction izaba 3.2 ohm, ikubye inshuro 80 kurwanya.Kumurongo wohereza amashanyarazi menshi, kugabanya reaction nurufunguzo rwo kuzamura ingufu zogukwirakwiza.

Bihuye na reaction, hariho na capacitive reaction, iringaniza muburyo butandukanye.Iyo inshuro nyinshi, niko ubushobozi bwa reaction ya capacitivite nini nini yo kuva kumurongo.Niba inshuro nyinshi ari nyinshi, kumeneka kumurongo nabyo biziyongera.

Ikindi kibazo ni umuvuduko wa generator.Imashini itanga amashanyarazi muri rusange ni imashini imwe-imwe, ni ukuvuga inkingi ya magneti.Kugirango ubyare amashanyarazi 50Hz, rotor irazunguruka 3000 rpm.Iyo umuvuduko wa moteri ugeze 3.000 rpm, urashobora kumva neza moteri yinyeganyeza.Iyo ihindutse 6,000 cyangwa 7,000 rpm, uzumva ko moteri iri hafi gusimbuka muri kode.

Moteri yimodoka iracyari nkiyi, tutibagiwe na rotor ikomeye yicyuma hamwe na turbine ya parike ipima toni 100, ari nayo mpamvu itera urusaku rwinshi rwuruganda rwamashanyarazi.Rotor yicyuma ipima toni 100 kuri rewolisiyo 3000 kumunota biroroshye kuvuga kuruta gukora.Niba inshuro zirenze eshatu cyangwa enye hejuru, byagereranijwe ko generator ishobora kuguruka mumahugurwa.

Bene rotor iremereye ifite inertia nyinshi, nayo ikaba isobanura ko sisitemu yingufu yitwa sisitemu idahwitse kandi ishobora gukomeza gukora neza kandi ihamye.Niyo mpamvu kandi amasoko y'amashanyarazi rimwe na rimwe nk'umuyaga n'izuba birwanya amasoko gakondo.

Kuberako ibibera bihinduka vuba, rotor ipima toni mirongo iratinda cyane kugabanya cyangwa kongera umusaruro bitewe nubusembure bunini (igitekerezo cyumuvuduko ukabije), budashobora kugendana nimpinduka zingufu zumuyaga no kubyara amashanyarazi, bityo rero rimwe na rimwe bigomba gutereranwa.Umuyaga n'umucyo wataye.

Birashobora kugaragara uhereye aha

Impamvu ituma inshuro zidashobora kuba nke cyane: transformateur irashobora gukora neza cyane, kandi moteri irashobora kuba nto mubunini kandi nini mumbaraga.

Impamvu ituma inshuro zitagomba kuba ndende cyane: gutakaza imirongo nibikoresho birashobora kuba bito, kandi umuvuduko wa generator ntukeneye kuba mwinshi cyane.

Kubwibyo, ukurikije uburambe ningeso, ingufu zacu zamashanyarazi zashyizwe kuri 50 cyangwa 60 Hz.
