Iyo frequency kutendeuka uye yekumhanyisa kudzora kushanda kwemota zvishoma nezvishoma yave chiratidzo chenguva.Iyo yekumhanyisa kudzora kweiyo synchronous mota ndiyo frequency kutendeuka uye yekumhanyisa kudzora kudzora kweyakaenzana torque mutoro muchina senge fan uye pombi inofambiswa neiyo frequency kutendeuka uye nekumhanya kudzora kweiyo AC mota mukugadzira maitiro.Frequency yekushandura yekumhanyisa regulation control inogona kuwana yakanakisa maitiro maitiro uye yakakura kuchengetedza simba uye kuderedzwa kwekushandisa.

simba rekuchengetedza simba

Michina yemidziyo inofambiswa neyechinyakare brushless excitation synchronous mota, senge mafeni, pombi, uye compressors, inoshanda pasi pesimba frequency uye simba rinobuda rinogara.Kana iyo nzira inogadzirisa kuyerera kwayo uye kumanikidza, inokonzeresa kutambisa kwakakomba kwesimba.Nekuti mutoro unoshanduka, chiyero chekuyerera chakaenzana nekumhanya, uye simba rinodiwa rinoenderana necube yekumhanya.Naizvozvo, kana chiyero chinodiwa chekuyerera chiri 80% yeyero yakayerwa yekuyerera, mune ino mamiriro echokwadi, kushandiswa kwemazuva ano frequency conversion kumhanyisa regulation otomatiki kutonga kunogona kuchengetedza kupfuura 45% yemagetsi emagetsi pane echinyakare nzira yekudzora.

Frequency conversion operation process control

The frequency conversion speed regulation operation is a stand-alone control system.Iyo frequency yekushandura yekumhanyisa kudzora mashandiro ekuita yakangofanana neiyo frequency yekushandura yekumhanyisa regulation yakapfava yekutanga maitiro, asi pane misiyano.Iyo cranking drive mota inoityaira kutenderera.Kana iyo yekutenderera kumhanya kweiyo synchronous mota yasvika 1% yekumhanya yakayerwa, iyo synchronous mota inoraira iyo control system zvinoenderana nechirongwa chakagadzirirwa mushure mekubatidzwa kwekutonga, uye iyo general control room inoburitsa "mvumo yekubatidza. ” “, kureva kuti, vhara yakapfava yekutanga high voltage switch chiratidzo cheiyo frequency conversion yekumhanyisa regulation operation.Panguva imwecheteyo, zvinoenderana nemirairo yechiratidzo, iyo general control room pakarepo inovhara yakakwira-voltage switch ye main control circuit ye ​​soft start control system ye synchronous motor frequency conversion speed regulation operation, kuitira kuti synchronous motor iri mukati. iyo yakapfava yekutanga kushanda mamiriro eiyo frequency kutendeuka yekumhanyisa regulation control.

Munguva yekunyorova kwekutanga kudzora maitiro eiyo frequency kutendeuka uye frequency modulation yeiyo synchronous mota, iyo polarity ye rotor magineti danda reiyo synchronous mota inoramba isina kuchinjika, uye kutenderera kunokwidziridzwa nekuwanda kweiyo frequency shanduko yekumhanya mutemo, uye voltage. uye frequency inowedzerwa zvishoma nezvishoma kuita kuti synchronous mota imhanye pakumhanya kwakayerwa.Frequency kutendeuka kumhanya murau nyoro kutanga kudzora.

Munguva yekushanda kweiyo synchronous mota ine inosiyana frequency kumhanyisa regulation, zvinoenderana nekuchinja kwemutoro chaiwo, iyo frequency conversion yekumhanyisa regulation system uye iyo microindasitiri inodzora yemagetsi komputa yekudzora system inoziva yakagadzikana uye chaiyo yekumhanyisa kudzora kwevector mashandiro ekutonga. .

Pamberi pekumira kweiyo synchronous mota muiyo frequency kutendeuka yekumhanyisa regulation mashandiro, iyo frequency yekushandura yekumhanyisa dhizaini yekushandisa inofanirwa kudzikisa otomatiki inobuda kusvika zero, uye ichivharira ese anokonzeresa mapurusi eiyo frequency yekushandura yekumhanyisa regulation dhizaini isati yagona kupa "mvumo yekumira" chiratidzo chekuratidzira.Zvinoenderana nekuraira kwechiratidzo chakaratidzwa, tenzi kudzora pakarepo anocheka yakakwira-voltage switching magetsi eiyo main control circuit ye ​​frequency conversion speed regulation operation control device, uye inopedza frequency conversion speed regulation operation control process.
