Ngenxa yokuba i-inverter isebenzisa amanqanaba ombane ombane ohlukeneyo, kuyimfuneko ukubonelela ngamanqanaba ahlukeneyo ombane xa ugcina i-inverter.Nangona kunjalo, i-voltage yokwenyani yesigaba sesithathu se-200v AC okanye isigaba sesithathu sombane we-400v AC ayifuneki ngokuyimfuneko kugcino lwenqanaba lebhodi okanye nokugcinwa kwenqanaba letshiphu (kungenjalo, xa ugunyazisa umthwalo).Into efunekayo yi-200v kunye ne-400v AC yombane kunye ne-300v kunye ne-500v DC yombane.Nangona kukho iintlobo ezininzi zonikezelo lwamandla e-DC oluhlengahlengiswayo kwimarike, ziyabiza kwaye umsebenzi wokhuselo awufanelekanga.Kwiminyaka emininzi yomsebenzi wokulondoloza, umbhali wenze umbane okhethekileyo we-inverter chip level kunye neziphumo zombane we-AC kunye ne-DC kunye nemisebenzi epheleleyo yokukhusela.
Indlela yokuvelisa I ye-inverter yogcino lwamandla ombane:
IBhili yeMathiriyeli:
1 AC umnxibelelanisi 220V 32A Ubuninzi: 2
I-2 Transformer 220V ukuya kwi-380V 500W isigaba esinye Ubuninzi: 1
3 Inani lamaqhosha azitshixelayo (indawo SB SB1) 2
4 Imodeli yebhulorho ehlaziyiweyo MDQ100A Ubuninzi: 1
I-5 yokuchasa i-resistor (isikhundla se-RL) 120W60R Ubuninzi: 1
6 I-Electrolytic capacitor (isikhundla C1 C2 C3 C4) 400V680UF Ubuninzi: 4
7. I-Voltage equalizing resistor (indawo RC1 RC2 RC3 RC4), i-resistor 2W180k, ubungakanani 4
8 DC voltmeter, DC1000V uhlobo lwesalathisi
9 Ukukhutshwa kokumelana (isikhundla se-RB) 120W60R Ubuninzi: 1
Imizobo:
Indlela yesi-II yokwenza umbane wogcino lwe-inverter:
Ezinye iivenkile zolondolozo, ezilinganiselwe ngokwemiqathango, azinawo umbane wolondolozo lwezigaba ezithathu, nto leyo ezisa ukuphazamiseka ekugcinweni kwee-inverters, ngakumbi i-AC kunye ne-DC voltage regulators (iziqalisi ezithambileyo) kunye nezinye izixhobo zombane.
Emva kovavanyo oluninzi kunye nokulungiswa okufanelekileyo kolwakhiwo, unikezelo lwamandla ombane amanqanaba amathathu lwenziwa kwaye i-waveform ephumayo yavavanywa.MholoI-waveform entle, isondele kakhulu kubonelelo lwamandla.
Njengoko kubonisiwe kulo mfanekiso:
Xa i-frequency converter kunye ne-380V unikezelo lwamandla amanqanaba amathathu ihlanganiswe, i-KT1 ukulibaziseka ukutshaja isekethe iya kongezwa, kwaye iiparamitha zayo zinokufana nezo zesekethe yokutshaja yangaphakathi.I-transformer yodwa ithatha umlinganiselo we-1: 1 wenguqu;Ukuba i-converter ene-220V yegalelo lombane isetyenzisiweyo, ikhonkco ye-KT1 yangoku yokukhawulela ingashiywa, kwaye i-220: 380 i-step-up transformer isetyenziswa njenge-transformer yodwa.Ukuba i-R2=R1 ikhethiwe, umthamo woqhagamshelwano we-KT1 kufuneka ube mkhulu kuno-5A.Ukuba ayanelanga, kufuneka kongezwe i-relay.
Njengoko kufunwa, i-T1T2 inokudityaniswa ngokwemveliso yangoku ye-converter frequency.Ndisebenzisa i-inverter yesandla sesibini, isiguquli sokwahlula kunye ne-reactor engasebenziyo kwaye kulula ukuyifumana.
Ukuba kukho imfuneko, isekethe yokucoca isihluzi singongezwa kwinqanaba lamva ukufumana i-0 ~ 550V ehlengahlengiswayo yogcino lwamandla ombane weDC.Xa imveliso ye-waveform ingafanelekanga, zama ukuhlengahlengisa i-frequency carrier ye-converter ukuze iqhelane nexesha lokucoca i-LC rhoqo, ukuze ufumane imveliso engcono ye-waveform.
