Ichatshazelwa yiRussia kunye neUkraine, ii-inverters zithandwa kakhulu

Ii-inverters zahlulwe kakhulu zibe ziindidi ezimbini ngokohlobo lwamaza:

1. Isiguquli samaza esisulungekileyo 2. Isiguquli samaza esilungisiweyo 3. Isiguquli samaza esikwere.

I-square-wave inverters ikhupha i-square-wave ye-square-wave etshintshanayo ngoku, kwaye iincopho zazo ezintle kunye nezibi zenziwa phantse ngaxeshanye, eziya kuwonakalisa umthwalo kunye ne-inverter.Ngaphezu koko, umthamo womthwalo we-square wave inverter uhlwempuzekile, kuphela malunga nesiqingatha samandla alinganisiweyo, kwaye awukwazi ukuthwala umthwalo owenziweyo.

Xa kuthelekiswa ne-square wave inverter, i-voltage ye-voltage ephumayo ye-sine wave inverter iphuculwe kakhulu, kwaye umxholo ophezulu we-harmonic nawo uyancitshiswa.Isiguquli soguqulo se-sine esilungisiweyo senziwa ngokunyuka ngokuthe ngcembe kwee-voltages zamaza achaseneyo.Ngale ndlela, isiphaluka solawulo sinzima, kukho iibhubhu zokutshintsha amandla amaninzi kwimigca ephezulu, kwaye umthamo kunye nobunzima be-inverter zikhulu.Kwiminyaka yakutshanje, ngophuhliso olukhawulezayo lwetekhnoloji ye-elektroniki yamandla, ukumodareyitha kobubanzi bokubetha kwe-PWM kusetyenziswe ngokubanzi ukuvelisa imveliso yolungiso lwamaza.Okwangoku, i-wave inverter ephuculweyo isetyenziswe ngokubanzi kwiinkqubo zabasebenzisi kwiindawo ezikude, kuba ezi nkqubo zabasebenzisi azinazo iimfuno eziphezulu kumgangatho wokusetyenziswa kwamandla, kwaye i-inverter ephuculweyo ifanelekile ukuthwala ukuchasana.

I-sine wave inverter ecocekileyo ikhupha amandla aphezulu e-AC, anokuqhuba iintlobo ngeentlobo zemithwalo, kwaye ngokusisiseko ayinamonakalo kumthwalo kunyeinverter.Nangona ii-inverters ze-sine ezisulungekileyo zixabisa ngaphezulu kwe-square wave kunye nee-inverters ezilungisiweyo ze-sine, sisacebisa ukuba ukhethe ii-inverters ezisulungekileyo ze-sine xa kunokwenzeka.

Imveliso yombane waveform yeinverter ecocekileyo ye-sine wavekulungile, ukugqwetheka kuphantsi kakhulu, kwaye imveliso yayo yamaza ihambelana ngokusisiseko ne-AC waveform yegridi yamandla.Ngapha koko, i-sine wave inverter ebalaseleyo inokubonelela ngamandla e-AC aphezulu kunegridi.I-sine wave inverter inokuphazamiseka okuphantsi koonomathotholo kunye nezixhobo zonxibelelwano kunye nezixhobo ezichanekileyo, ingxolo ephantsi, kunye nokuguquguquka komthwalo onamandla, onokuhlangabezana nazo zonke izicelo zomthwalo we-AC, ukusebenza kakuhle kuphezulu.Ukungalungi kwayo kukuba i-circuit kunye ne-retraver correction wave inverter transformer iyinkimbinkimbi, ifuna ii-chips zokulawula eziphambili kunye neteknoloji yokulondoloza, kwaye zibiza kakhulu.Kwimeko yosetyenziso oluqhagamshelwe kwigridi yelanga, i-sine wave inverter kufuneka isetyenziswe ukuthintela ukungcoliseka kombane kwigridi yoluntu.
