Nei mota ichifanira kusarudza 50HZ AC? |

Mota vibration ndeimwe yeazvino anoshanda mamiriro emotor. Saka, unoziva here kuti nei michina yemagetsi yakaita semotor inoshandisa 50Hz alternating current pachinzvimbo che60Hz?

Dzimwe nyika pasi rose, dzakaita seUnited Kingdom neUnited States, dzinoshandisa 60Hz alternating current, nekuti dzinoshandisa decimal system, chii nyeredzi gumi nembiri, maawa gumi nemaviri, mashillingi gumi nemaviri akaenzana nepondo imwe zvichingodaro.Nyika dzakazotevera dzakatora decimal system, saka frequency ndeye 50Hz.

Saka nei tichisarudza 50Hz AC pachinzvimbo che5Hz kana 400Hz?

Ko kana frequency yakaderera?

Iyo yakaderera frequency ndeye 0, inova DC.Kuti aratidze kuti Tesla alternating current ine ngozi, Edison akashandisa alternating current kuvhota vhoti yemhuka diki. Kana nzou dzichionekwa semhuka diki… Nechinangwa, pasi pehukuru hwazvino, muviri wemunhu unokwanisa kushingirira ikozvino kwenguva yakareba kupfuura Nguva yekutsungirira kuchinjika ikozvino ine chekuita ne ventricular fibrillation, ndiko kuti, kuchinjanisa ikozvino kune njodzi.

Cute Dickson akarasikirwa zvakare naTesla mukupedzisira, uye AC yakarova DC nemukana wekuchinja zviri nyore giredhi.Panyaya yesimba rimwe chete rekutapurirana, kuwedzera vhezheni kunoderedza kutapurirana ikozvino, uye simba rinopedzwa pamutsetse richadererawo. Rimwe dambudziko rekufambiswa kweDC nderekuti inonetsa kutyoka, uye dambudziko iri richiri dambudziko kusvika zvino.Dambudziko rekufambiswa kweDC rakafanana nespark inoitika kana plug yemagetsi ichiburitswa panguva dzakajairwa. Apo ikozvino inosvika pane imwe nhanho, spark haigoni kudzima. Isu tinodaidza kuti "arc".

Pakuchinjisa ikozvino, ikozvino inochinja nzira, saka pane nguva iyo ikozvino inoyambuka zero. Tichishandisa iyi diki yazvino nguva poindi, tinogona kucheka mutsara wazvino kuburikidza nearc yekudzima mudziyo.Asi kutungamira kweDC ikozvino hakuzochinji. Pasina iyi zero-cross point, zvingava zvakaoma kwatiri kudzima arc.

Chii chakashata ne low frequency AC?

Kutanga, dambudziko rekushanda kwetransformer

Iyo transformer inovimba neshanduko yesimba remagineti padivi rekutanga kuona nhanho-kumusoro kana nhanho-pasi yedivi rechipiri.Iyo inononoka kuwanda kweiyo magnetic field inoshanduka, iyo inoderera induction. Iyo yakanyanyisa kesi ndeye DC, uye hapana induction zvachose, saka frequency yakanyanya kuderera.

Chechipiri, dambudziko remagetsi emagetsi emagetsi

Semuenzaniso, kumhanya kweinjini yemotokari ndeye frequency yayo, senge 500 rpm kana idling, 3000 rpm kana ichimhanyisa uye ichichinja, uye mafambiro akashandurwa ari 8.3Hz uye 50Hz zvichiteerana.Izvi zvinoratidza kuti kukurumidza kukuru, ndiko kukura kwesimba rejini.

Nenzira imwecheteyo, panguva imwe chete, iyo injini yakakura, simba guru rinobuda, ndicho chikonzero injini dzedhiziri dzakakura kudarika peturu, uye injini dzedhiziri dzakakura uye dzine simba dzinogona kutyaira motokari dzinorema semarori emabhazi.

Nenzira imwecheteyo, mota (kana ese anotenderera muchina) inoda ese diki saizi uye hombe inobuda simba. Pane nzira imwe chete - kuwedzera kukurumidza, ndicho chikonzero kuwanda kweiyo alternating ikozvino haigone kuve yakaderera, nekuti tinoda diki diki asi simba rakakura. mota yemagetsi.

Izvi zvakafanana kune inverter air conditioners, iyo inodzora kubuda kwesimba re air conditioner compressor nekushandura frequency yealternating current.Muchidimbu, simba uye kuwanda kwakabatana zvakanaka mukati mehumwe huwandu.

Ko kana frequency yakakwira?Semuenzaniso, zvakadini ne400Hz?

Kune matambudziko maviri, imwe ndeyokuti kurasikirwa kwemitsara uye midziyo inowedzera, uye imwe yacho ndeyokuti jenareta inotenderera nokukurumidza.

Ngatitange tataura nezvekurasikirwa. Matanho ekutakurisa, midziyo yemagetsi, uye midziyo yemagetsi zvese zvine react. Reactance yacho inoenderana ne frequency. zvishoma.

Parizvino, kuita kweiyo 50Hz yekufambisa mutsara inenge 0.4 ohms, iyo inenge ka10 kanopikisa. Kana yakawedzera kusvika 400Hz, reactance ichava 3.2 ohms, iyo inenge 80 nguva yekupikisa.Kune ma-high-voltage transmission lines, kuderedza reactance ndiyo kiyi yekuvandudza simba rekutapurirana.

Zvinoenderana nekuita, kune zvakare capacitive reactance, iyo inversely proportional kune frequency. Iyo yakakwirira iyo frequency, idiki iyo capacitive reactance uye yakakura yekudonha ikozvino yemutsetse.Kana iyo frequency yakakwira, iyo yekudonha ikozvino yemutsetse ichawedzerawo.

Rimwe dambudziko nderekumhanya kwejenareta.Ikozvino jenareta seti ndeyemuchina wechikamu chimwe chete, kureva, peya yemagineti mapango.Kuti ugadzire magetsi e50Hz, rotor inotenderera pa3000 rpm.Kana injini yekumhanya inosvika 3,000 rpm, unogona kunyatsonzwa injini ichidedera. Kana yasvika 6,000 kana 7,000 rpm, unonzwa kuti injini yave kuda kusvetuka kubva muhood.

Injini yemotokari ichiri seizvi, tisingarevi simbi yakasimba bundu rotor uye turbine yemhepo inorema matani zana, inovawo chikonzero chekurira kukuru kwesimba remagetsi.A iron rotor inorema matani zana pa3,000 revolutions paminiti iri nyore kutaura pane kuita. Kana iyo frequency iri katatu kana kana yakakwira, inofungidzirwa kuti jenareta inogona kubhururuka kunze kwewekishopu.

Rotor inorema yakadaro ine inertia yakakura, iyo zvakare chirevo chekuti iyo simba system inonzi inertial system uye inogona kuchengetedza yakachengeteka uye yakagadzikana kushanda.Ndosaka zvakare matsime emagetsi emagetsi akadai semhepo uye solar achinetsa matsime emagetsi echinyakare.

Nekuti nzvimbo inochinja nekukurumidza, ma rotor anorema matani akawanda anononoka kudzikisa kana kuwedzera kuburitsa nekuda kweiyo inertia hombe (pfungwa yeramp rate), iyo isingakwanise kuenderana nekuchinja kwesimba remhepo uye photovoltaic simba rekugadzira, saka. dzimwe nguva inofanira kusiiwa. Mhepo uye chiedza chakasiiwa.

Inogona kuonekwa kubva pane izvi

Chikonzero nei iyo frequency haigone kuve yakaderera: iyo transformer inogona kuve yakanyatso shanda, uye mota inogona kuva diki muhukuru uye yakakura musimba.

Chikonzero nei kuwanda kusingafaniri kunge kwakanyanyisa: kurasikirwa kwemitsara nemichina inogona kuva duku, uye jenereta inomhanya haifaniri kunge yakanyanyisa.

Naizvozvo, maererano neruzivo uye tsika, simba redu remagetsi rinoiswa pa50 kana 60 Hz.
