Synchronous michina uye injini

Mufananidzo we jorts

Ndiwo machina ane kumhanya kwenhamba yakapihwa yemapango akasiyana uye anotarirwa netiweki frequency. Kuwanda kuri kuita nhamba yematenderedzwa pachikamu chenguva. Chishwe chimwe nechimwe chinopinda padanda rokumusoro nedanda rezasi.

f=p*n/60

MuEurope uye mune dzakawanda pasirese frequency yemaindasitiri network ndeye 50Hz uye muUSA nedzimwe nyika i60Hz)

Kana ichishanda sejenareta, kumhanya kwemuchina kunofanirwa kuve kwakanyatso kuenderana.

Kubva pane fomula zvinotevera kuti muchina unopindirana, unoshanda semota, utenderere nekumhanya kwakasiyana, unofanirwa kudyiswa neinosiyana frequency, iyo yakanangana nekumhanya kwega kwega. Asi sezvo magetsi emagetsi anopihwa nemaindasitiri network ane frequency yakatarwa, frequency inverter inodiwa.

Kubatsirwa

  • Inoshanda nepamusoro-soro simba chinhu chisingadi kugadziriswa, kuchengetedza simba nemari.
  • Iyo inochengetedza inogara ichimhanya, inozviwiriranisa, kunyangwe kune mitoro misiyano.
  • Iine maitiro epamusoro uye akanyatsogadzikana.
  • Iyo mota torque inoenderana nevoltage uye mune asynchronous mota inoenzanirana ne square yevoltage. Saka, mhedzisiro yekudonha kwevoltage mumambure ishoma
  • Mhepo yemhepo yakakura, iyo inowedzera kuchengetedzwa kwemichina.

Nekuda kweaya mabhenefiti, mumadhiraivha eMegawatts uye anogara achimhanya, iyo synchronous mota inodyiswa kubva kunetiweki ndeyekushandisa kukuru.

Zvipingamupinyi

  • A synchronous motor haigone kutanga yega. Kuti zvishande isu tinofanirwa kuvaunza kuti vaenderane nekukurumidza. Naizvozvo tinoda mamwe magadzirirwo ekutanga.
  • Kana paine misiyano kamwe kamwe mumutoro, kumhanya kwesynchronism pakati pe frequency uye kumhanya kunogona kurasika uye muchina unomira.
  • Boot matambudziko uye kugadzikana matambudziko.

Muchina wesynchronous unopihwa simba zvakananga kubva kune maindasitiri network, mumusimboti, hauna kunyatsokodzera kushandiswa semota.

Kana isu tichiona muchina muyakagadzirwa modhi, kunyangwe kubva painotioretical nzvimbo yekuona haina hanya kuve neiyo inductor matanda mu stator uye loop mu rotor ine loop yakaiswa mu stator slots uye inductor matanda akadyiswa neakananga ikozvino kuburikidza. zvindori zviviri zvinotsvedza nemabhurashi kana zvakasiyana. Padanho retekinoroji uye rinovaka harina kufanana uye kugadzirisa kunoshandiswa.

Kuti ushande zvakanaka, iwo ma AC voltages anofanirwa kunge akafanana sezvinobvira kune sine wave. Nokuda kweizvi, kune rumwe rutivi, kugadziridzwa kwepakati kwemhepo induction wave inogadziriswa uye, kune imwe, loop inotsiviwa nemhepo yakaoma yakaoma.

Nekugadziriswa kwematatu diametric makoiri ane matatu akazvimirira mabudiro uye 120º kunze kwechikamu kuti uwane matatu-chikamu system.

Mumakore achangopfuura, nekuda kwekuwanikwa uye kuvandudzwa kwezvinhu zvine yakanaka kwazvo magineti zvivakwa nesamarium, cobalt uye isingawanzo pasi, masynchronous motors ane magineti echigarire ari kushandiswa, pasina mhepo mukunakidzwa.

Zvakanakira zvechigarire magineti mota

Kusavapo kwezvindori zvindori uye mabhurashi. Zvinetso zvekuchengetedza zvine chekuita nezvikamu zvinofamba, izvo zvaive zvakanyanya kuoma zvikamu zveinjini, zvinopera

Sezvo pasina kuputika kwemhepo, Joule kurasikirwa mu rotor kunobviswa, kuvandudza kushanda uye kuita kuti zvive nyore kutonhora.

Zvakaipa zvachose magineti

Tsika yekubvisa magineti yemagineti nekuda kwemafungu makuru ari musimba uye nekuda kwekupisa kwakanyanya kunosvika panguva yekushanda kwemota.

Iko kufara kwakagadziriswa uye kukosha uku hakugoni kuchinjwa. Izvo zvinoderedza zvirongwa zvekushandisa injini.

Iwe unogona kuva uchifarira kutonga nekudzivirira kwemaindasitiri emagetsi mota.

padanho reindasitiri

Munda wekushandisa par kunaka kwemakina anowirirana ndiko kugadzirwa kwesimba remagetsi.

Inenge simba rose remagetsi rinogadzirwa rinogadzirwa kuburikidza nemichina inopindirana mune yavo generator version. Avhareji yejenareta inopindirana inogona kuva pakati pe3 ne100 MVA uye mumagetsi emagetsi enyukireya anosvika 300 - 1000 MVA. Iine 1500KV zvakabuda uye zvinoyerera zvehurongwa hwekA.

Semotokari, anoshandiswa zvakanyanya muhuwandu hwe3 kusvika ku30 Megawatts, achikwikwidzana neasynchronous.

Nhasi, ine convertomachines, yemagetsi inoshandura gungano pamwe nemuchina wesynchronous, vari kukwikwidza kunyangwe masimba ari pasi pe10kW, kunyangwe nekumhanya kwakasiyana. Iri gomo rinodhura zvakanyanya nekuda kwekushandura. asi zviri kutobatsira mumaindasitiri kune masimba iwayo. kukwikwidza neDC motors uye asynchronous motors.
