Iri Variable Frequency Drive Inogona Kutsiviwa NeMota Yakapfava Starter?

Iri Variable Frequency Drive Inogona Kutsiviwa NeMota Yakapfava Starter?

Ndiri kusangana nevatengi vakawanda vanondibvunza mibvunzo yakawanda uye ndine rukudzo kusangana navo uye kutaura navo nezve mota yekutanga kutonga.Vamwe vevatengi vanogara vachishamisika kanafrequency drivesinogona kutsiviwa nesoft starters.Nhasi ndichakupa imwe pfungwa:

1. Nheyo yekudzora ye soft starter uye frequency converter yakasiyana

Iyo huru yedunhu reiyo yakapfava inotangira yakabatana munhevedzano pakati pesimba rekupa uye mota mumatatu akatarisana akafanana thyristor, kuburikidza nemukati dhijitari redunhu kudzora thyristor mune yakazara sinusoidal waveform yekuchinjisa ikozvino kutendeuka-nguva, kana pakutanga. ye AC cycle rega thyristor itendeuke, ipapo iyo yakapfava inoburitsa voltage yakakwira, Kana thyristor ikabatidzwa pane imwe nzvimbo mukutenderera kwealternating current, kubuda kwevoltage yesoft starter yakaderera.Nenzira iyi, tinoita kuti voltage pamagumo emotokari iwedzere zvishoma nezvishoma mukutanga, uye todzora kutanga ikozvino uye torque yemotokari, kuitira kuti motokari iwane chinangwa chekudzikama kutanga.Zvinogona kuonekwa kuti iyo nyoro inotangira inogona kungoshandura huwandu hwemagetsi emagetsi emagetsi, asi kwete kuwanda kwehuwandu hwemagetsi.
Nheyo yefrequency converter yakanyanya kuoma.Basa rayo ndere kushandura voltage ye 380V/220V uye frequency ye50HZ simba rekupa kuita AC simba rekushandura mudziyo ine inogadziriswa voltage uye frequency.Nekugadzirisa kuwanda uye kuwanda kweiyo magetsi, iyo torque uye kumhanya kweiyo AC mota inogona kugadziriswa.Dunhu rayo guru idunhu rinoumbwa ne6 field effect tubes, pasi pekutonga chaiko kwedunhu rekutonga, kuitira kuti machubhu matanhatu emumunda atendeuke, munguva yeyuniti, iyo yakawanda nhamba yechubhu pa, ipapo kubuda kwemagetsi uye frequency. yakakwira, saka dunhu guru riri pasi pekutonga kwedhijitari yekudzora dunhu kuti iwane frequency regulation yeinobuda magetsi ekupa uye voltage regulation.

2. Mashandisirwo esoft starteruye inverter zvakasiyana

Dambudziko guru rekutanga rakapfava nderokudzikisa kutanga ikozvino kwekuremerwa uye kuderedza kukanganiswa kwemagetsi grid.Kutanga-kumusoro kwemidziyo mikuru kuchaburitsa yakakura kwazvo yekutanga ikozvino, izvo zvinokonzeresa kudonha kukuru kwemagetsi.Kana iyo yechinyakare nhanho-pasi modhi senge nyeredzi katatu ikashandiswa, haizongokonzeresa yakakura ikozvino kukanganisa pane gidhi remagetsi, asi zvakare inokonzeresa hombe yemagetsi kukanganisa pamutoro.Mune ino kesi, nyoro yekutangisa inowanzo shandiswa kutanga, kuitira kuti uone yekutanga yese pasina kukanganisa uye kuita kuti mota itange yakatsetseka.Saka simba shoma simba.

Kushandiswa kwefrequency converterinonyanya kushandiswa munzvimbo ine kumhanya mutemo, inogona kudzora kumhanya kweiyo-nhatu-chikamu mota, senge muCNC muchina chishandiso spindle mota yekumhanyisa regulation, mechanical conveyor belt transmission control, mafeni mahombe, anorema ma mechanical application anogona kushandiswa mu iyo frequency converter, kazhinji, basa rayo rinonyanya kushanda kupfuura nyoro yekutanga.

3. Basa rekutonga refrequency converter ye soft starter yakasiyana

Basa guru reiyo yakapfava dhizaini nderekugadzirisa vhezheni yekutanga yemotor kuti ione kutsetseka kwemota kuti ideredze kukanganiswa kwemota pamakina uye gidhi remagetsi.Nekudaro, nekuti inodzora voltage nechopper kuburikidza nekudzora conduction Angle, iyo inobuda haina kukwana sine wave, iyo inotungamira kune yakaderera yekutanga torque, ruzha rukuru uye yakakwirira harmonics inosvibisa gidhi remagetsi.Kunyangwe iyo yakapfava inotangira inogumira pakugadzika kwerukova basa, kugadzika kwekutanga nguva uye mamwe mabasa, asi neinoshandura frequency, maparamita anoshanda eiyo soft starter akanyanya kunyangadza.Kazhinji, basa rekutanga rakapfava harina kuenzana ne frequency converter.

4. Mutengo wesoft starter yakasiyana neiyo frequency converter

Iwo maviri ekudzora midziyo mune imwechete simba mamiriro, kubva pamutengo weiyo inverter wakakwira kupfuura iyo nyoro yekutanga.

Kazhinji, nyoro yekutangisa inonyanya kushandiswa kune yakakwirira-simba midziyo seyekutanga mudziyo, uye frequency converter inonyanya kushandiswa kumhanyisa kudzora kwesimba rakasiyana.Muzviitiko zvakawanda, iyo frequency converter haigone kutsiviwa neyekutanga nyoro.
