Nekuti iyo inverter inoshandisa akasiyana magetsi emagetsi mazinga, zvinodikanwa kuti upe akasiyana mazinga evoltage kana uchichengetedza inverter.Nekudaro, iyo chaiyo-yechitatu-chikamu 200v AC voltage kana matatu-chikamu 400v AC voltage haidiwi kudiwa pabhodhi level kugadzirisa kana kunyangwe chip level kugadzirisa (zvikasadaro, kana uchitumwa nemutoro).Izvo zvinodiwa ndeye 200v uye 400v AC voltage uye inoenderana 300v uye 500v DC voltage.Kunyangwe kune akawanda marudzi eanogadziriswa DC magetsi emagetsi pamusika, anodhura uye basa rekudzivirira harina kunaka.Mumakore mazhinji ebasa rekugadzirisa, munyori akagadzira yakakosha inverter chip level kugadzirisa magetsi neaviri AC uye DC voltage kubuda uye akazara ekudzivirira mabasa.
Kugadzira nzira I ye inverter kugadzirisa magetsi ekupa:
Bhiri reZvishandiso:
1 AC contactor 220V 32A Huwandu: 2
2 Transformer 220V kusvika 380V 500W Single phase Quantity: 1
3 Nhamba yemabhatani ekuzvivharira wega (chinzvimbo SB SB1) 2
4 Rectifier bhiriji modhi MDQ100A Huwandu: 1
5 Kuchaja resistor (chinzvimbo RL) 120W60R Huwandu: 1
6 Electrolytic capacitor (chinzvimbo C1 C2 C3 C4) 400V680UF Kuwanda: 4
7. Voltage yakaenzana resistor (chinzvimbo RC1 RC2 RC3 RC4), resistor 2W180k, huwandu 4
8 DC voltmeter, DC1000V pointer mhando
9 Discharge resistor (chinzvimbo RB) 120W60R Huwandu: 1
Mifananidzo:
Nzira II yekugadzira inverter kugadzirisa magetsi:
Zvimwe zvitoro zvekuchengetedza, zvakaganhurirwa nemamiriro ezvinhu, hazvina matatu-chikamu chekugadzirisa magetsi, izvo zvinounza kusagadzikana mukugadziriswa kwemainverters, kunyanya AC uye DC voltage regulators (soft starters) uye zvimwe zvigadzirwa zvemagetsi.
Mushure mekuedzwa kwakati wandei uye kukwenenzverwa kwechimiro, matatu-chikamu inverter magetsi akagadzirwa uye yakabuda waveform yakaedzwa.Mhoro!Yakanaka waveform, padyo padyo nemagetsi.
Sezvinoratidzwa mumufananidzo:
Kana iyo frequency converter ine 380V matatu-phase magetsi emagetsi akaunganidzwa, iyo KT1 inononoka yekuchaja wedunhu ichawedzerwa, uye maparamita ayo anogona kunge akafanana neaya emukati yekuchaja wedunhu.Iyo yekuzviparadzanisa transformer inotora 1: 1 shanduko reshiyo;Kana iyo inoshandura ine 220V yekuisa magetsi ekushandisa ikashandiswa, iyo KT1 yazvino yekumisikidza link inogona kusiiwa, uye iyo 220:380 nhanho-kumusoro transformer inoshandiswa seyakasarudzika transformer.Kana R2=R1 yasarudzwa, huwandu hwekubatana hweKT1 hunofanira kunge hwakakura kupfuura 5A.Kana isina kukwana, relay inofanira kuwedzerwa.
Sezvinodiwa, T1T2 inogona kuenzaniswa zvichienderana nekubuda kwazvino kweiyo frequency converter.Ini ndinoshandisa yechipiri-ruoko inverter, yekuzviparadzanisa transformer uye reactor izvo zvisina basa uye zviri nyore kuwana.
Kana zvichidikanwa, rectifier sefa yedunhu inogona kuwedzerwa pane inotevera nhanho kuti uwane 0 ~ 550V inogadziriswa DC yekugadzirisa magetsi.Kana iyo yakabuda waveform isina kunaka, edza kugadzirisa iyo inotakura frequency yeinoshandura kuti ienderane neLC kusefa nguva nguva dzose, kuitira kuti uwane zvirinani waveform kubuda.
