Kuenzaniswa neasynchronous motors, magineti asingagumisynchronous motorsvane zvakanakira zviri pachena. Ivo vane hunyanzvi hwepamusoro, simba repamusoro, zviratidziro zvakanaka zvekuita, saizi diki, huremu huremu, kuderera kwekushisa kukwira, zvakakosha zvehunyanzvi mhedzisiro, uye zvirinani kunatsiridza kunaka kwegidhi remagetsi. zvinhu, kushandisa zvizere kugona kweiyo iripo magetsi grid, kuchengetedza mari mugetsi remagetsi, uye kugadzirisa zvirinani chiitiko che "bhiza hombe nengoro diki" mumidziyo yemagetsi.
01.Efficiency uye simba chinhu
Kana iyo asynchronous motor iri kushanda, iyo rotor winding inotora chikamu chemagetsi emagetsi kubva kune girasi remagetsi nekuda kwekunakidza, iyo inoshandisa simba remagetsi emagetsi. Ichi chikamu chesimba remagetsi chinopedzwa mumhepo inotenderera semhepo inopisa. Kurasikirwa uku kunotora 20-30% yekurasikirwa kwese kwemota, izvo zvinoderedza kushanda kwemota. Iyo rotor excitation current inoshandurwa kuita stator winding seye inductive current, iyo inoita kuti yazvino ipinde mu stator winding lag kuseri kwemagetsi grid voltage nekona, zvichikonzera kudzikira kwesimba remota. Mukuwedzera, kubva pakushanda uye simba factor curves yechisingaperi magineti synchronous motorsuye asynchronous motors (Mufananidzo 1), zvinogona kuonekwa kuti kana chiyero chekutakura (= P2 / Pn) chiri
Mushure mekunge magineti echigarire akaiswa mune rotor yeanogara magineti synchronous mota, iyo inogara magineti inoshandiswa kumisikidza rotor magineti. Munguva yekushanda kwakajairika, iyo rotor uye stator magineti inomhanya synchronously, hapana induced ikozvino mu rotor, uye hapana rotor kuramba kurasikirwa. Izvi chete zvinogona kuwedzera kushanda kwemotokari ne4% ~ 50%. Sezvo pasina induced current excitation in the hydromagnetic motor rotor, stator winding inogona kunge yakachena resistive load, ichiita iyo motor power factor inenge 1. Kubva pakubudirira uye simba factor curves yekusingaperi magnet synchronous motor uye asynchronous motor (Figure 1), zvinogona kuonekwa kuti kana chiyero chekuremerwa kwechigarire che magnetti chisingagumi uye kushanda kwayo kusingashanduki, simba rekushanda risingagadziriswi, simba rekushanda uye kushanda kwakawanda. kunyatsoshanda kuri> 80%.
02. Kutanga cabinet
Kana iyo asynchronous mota yatangwa, mota inodiwa kuti ive neyakakura yakaringana yekutanga torque, asi yekutanga ikozvino haina kunyanyokurisa, kuitira kudzivirira yakawandisa kudonha kwemagetsi mugidhi remagetsi uye kukanganisa kushanda kwakajairwa kwemamwe mamotor uye zvigadzirwa zvemagetsi zvakabatanidzwa kune gidhi remagetsi. Uye zvakare, kana yekutanga ikozvino yakakura kwazvo, iyo mota pachayo inozokanganiswa neakawandisa simba remagetsi. Kana rikatangwa kakawanda, panewo njodzi yekupisa mhepo. Naizvozvo, dhizaini yekutanga yeasynchronous motors inowanzotarisana nedambudziko.
Anogara magineti synchronous motors anowanzo shandisa asynchronous kutanga. Sezvo iyo rotor mhepo isingashande kana inogara magineti synchronous mota ichishanda zvakajairwa, pakugadzira iyo inogara magineti mota, iyo rotor inotenderera inogona kuzadzisa zvizere zvinodikanwa zveyakakwira yekutanga torque, semuenzaniso, iyo yekutanga torque yakawanda inowedzerwa kubva 1.8 nguva dzeasynchronous mota kusvika 2.5 nguva, kana kutokura, iyo inogadzirisa zviri nani chiitiko chebhiza "kudhonza bhiza" mumotokari diki.
3. Kushanda tembiricha kukwira
Sezvo iyo rotor inotenderera ine ikozvino inoyerera kana asynchronous mota iri kushanda, uye ikozvino inopedzwa zvachose muchimiro chekupisa simba, huwandu hukuru hwekupisa huchagadzirwa mumhepo inotenderera, iyo inowedzera kupisa kwemota uye kukanganisa hupenyu hwebasa remota. Nekuda kwekushanda kwakanyanya kwemagineti echigarire mota, hapana kurasikirwa kwekupokana mumhepo inotenderera, uye pane zvishoma kana kanenge pasina reactive ikozvino mu stator winding, izvo zvinoita kuti tembiricha yemota ikwire pasi uye kuwedzera hupenyu hwesevhisi yemota. 4. Mhedzisiro pakushanda kwemagetsi emagetsi
Nekuda kweiyo yakaderera simba chinhu cheiyo asynchronous mota, mota inotora huwandu hukuru hweiyo reactive ikozvino kubva kune yemagetsi gidhi, zvichikonzera huwandu hukuru hweazvino reactive mugidhi remagetsi, transformer midziyo uye magetsi ekugadzira magetsi, izvo zvinoderedza kunaka kweiyo gidhi remagetsi uye inowedzera mutoro pane gidhi remagetsi, transformer midziyo uye magetsi ekugadzira magetsi. Panguva imwecheteyo, iyo inoshandiswa ikozvino inoshandisa chikamu chemagetsi emagetsi mumagetsi emagetsi, midziyo yekushandura uye zvigadzirwa zvekugadzira magetsi, zvichiita kuti kuderera kwemagetsi emagetsi uye kukanganisa kushandiswa kwemagetsi kwemagetsi. Zvakare nekuda kwekushomeka kweiyo asynchronous mota, kuitira kuti isangane neinobuda simba zvinodiwa, zvinodikanwa kutora mamwe emagetsi emagetsi kubva kune gidhi remagetsi, zvichiwedzera kuwedzera kurasikirwa kwesimba remagetsi uye kuwedzera mutoro pamagetsi emagetsi.
Iko hakuna induction ikozvino excitation mune yekusingaperi magineti mota rotor, mota ine yakakwira simba chinhu, iyo inovandudza kunaka kweiyo grid yemagetsi uye kubvisa kudiwa kwekuisa compensator mugidhi remagetsi. Panguva imwecheteyo, nekuda kwehukuru hwepamusoro hwechigarire magineti mota, simba remagetsi rinochengetwa zvakare.
