Intshayelelo kwimisebenzi kunye neempawu zephaneli yokulawula isithando somlilo esiphakathi

Isincedisi esingundoqo sephaneli yokulawula isithando somlilo esiphakathi samanzi. Ibhodi yokulawula unikezelo lwamandla ombane ophakathi ubukhulu becala iqulunqwe unikezelo lwamandla ombane, umlawuli onikwe, umlawuli wokulinganisela, isekethe yolawulo lwesigaba, isekethe yokhuselo, isekethe yokuqala yokubala, i-inverter frequency tracking, i-inverter pulse formation, i-pulse amplification kunye ne-pulse transformer. Amacandelo ayo angundoqo asebenzisa ukusebenza okuphezulu, ukuxinana okuphezulu, i-ultra-large-scale ezinikeleyo i-DLJ iisekethe ezidibeneyo. Abahleli babini balandelayo baya kuza kukuxelela malunga nemisebenzi kunye neempawu zephaneli yokulawula yesithando somlilo esiphakathi.

Enye, umsebenzi wephaneli yokulawula isithando somlilo esiphakathi

1. Ukusetyenziswa kwemodyuli ezinikeleyo kunye nekhethekileyo edibeneyo ehlakaniphile yokulawula isithando somlilo esiphakathi ayikwazi ukuqinisekisa kuphela ubuninzi kunye nobukrelekrele benkqubo, kodwa iqinisekisa ukuzinza kwenkqubo. Uninzi lweebhodi ezikrelekrele zangaphambili zisebenzise izixhobo ezinokuphinda zibhaleke, njenge-single-chip, oomatshini bePLC, kwaye ngenxa yoku kubhalwa kwakhona, umxholo wenkqubo uya kutshatyalaliswa kwimekobume yokuphazamiseka okukhulu kombane kunye nokufudumeza okuphakathi.

2. Ububanzi be-pulse buhlengahlengiswa ngokuzenzekelayo. I-Inverter pulse ithatha i-pulse eguquguqukayo, kwaye ububanzi be-pulse butshintshwa ngokuhambelana nokusebenza okungafaniyo kokusebenza kwesithando somlilo esiphakathi ukukhusela i-inverter pulse transformer ekungeneni kwi-sub-saturation state. Umda okhokelayo we-pulse ophumayo uphezulu, kwaye i-waveform ayiguquki.

I-3, ukumodareyitha kukaloliwe okubetha kabini. Ukulungiswa kwesithando somlilo esiphakathi kwamkela ukumodareyitha kwe-double pulse train, engaqinisekisi kuphela ukuthembeka kwe-trigger, kodwa kunciphisa ukusetyenziswa kwamandla okubangela kunye nokuphucula ukuzinza kwebhodi.

4. Iphaneli yokulawula isithando somlilo esiphakathi inokuguquguquka okuqinileyo kwaye ilungele ukulawula unikezelo lwamandla ombane aphakathi kwama-50KW-5000Kw.

5.I-onboard phase sequence sequence adaptive circuit ithatha unikezelo lwamandla amanqanaba amathathu ukwenzela ungqamaniso oluthe ngqo ngaphandle kwe-synchronization transformer. Umgca ongenayo wesiphaluka esiphambili unokuzimela ngokulandelelana kwesigaba.

6. Inkqubo yokhuseleko eyakhelweyo kwimisebenzi emininzi. Ibhodi enye edibeneyo edibeneyo, edibanisa ukulungiswa, i-inverter, ukukhusela, kunye nokulawula ukuqala. Isithando somlilo esiphakathi silawula i-overvoltage ebhodini, i-overcurrent, umda wombane, umda wangoku, ukutshayela rhoqo, ukutshixa rhoqo, ukubonwa kwamafrikhwensi aphakathi, ukuqala kwakhona, ukunikezelwa kwamandla, iimpawu ezahlukeneyo zemo ezifana nenkqubo inenzuzo yokuthembeka okuphezulu, ukuchaneka okuphezulu. , ukulungiswa okulula, iikhomponenti ezimbalwa zokudlulisa, njl., ukulungiswa okucacileyo kunye nokugcinwa okufanelekileyo.

7. I-“RE” port ehlakaniphile idibanisa imisebenzi efana ne “start”, “stop”, “reset”, kunye “remote control”, okwenza ukusebenza kwesixhobo kube lula kunye nokuqonda.

8. I-rectifier synchronous voltage yesithando somlilo esiphakathi inoluhlu olubanzi oluguquguqukayo, kwaye inokusebenza ngokuqhelekileyo ukusuka kwi-220V ukuya kwi-750V.

9. Ukuqala kwe-buffer kunye nenkqubo yokufumanisa isiqalo esigqibeleleyo, ukuze lo mgca ukwazi ukuqonda ukuqalisa kwamandla apheleleyo (qala kuyo nayiphi na indawo ye-potentiometer yamandla)

10. Ngaphandle kwe-inverter yokugqibela yomqhubi wesithando somlilo ophakathi, zonke zihlanganiswe kwibhodi yesekethe eprintiweyo, kunye nezixhobo ezimbalwa ze-peripheral, akukho zixhobo zokubuyisela, isiphaluka esilula, ukulungiswa okulula, kunye nokugcinwa kakuhle. Nje ukuba inkqubo yolawulo isilele, buyisela nje ibhodi esecaleni. Nangona kunjalo, ayiyi kuchaphazela imveliso eqhelekileyo.　　

Okwesibini, iimpawu zepaneli yokulawula yesithando somlilo esiphakathi

I-1, isiphaluka solawulo sigxininiswe kwibhodi eprintiweyo

Zonke iisekethe zokulawula zesithando somlilo esiphakathi zisebhodini eprintiweyo, enciphisa kakhulu ukungaphumeleli okubangelwa uqhagamshelwano olubi lwezixhumi. Imowudi yokuqalisa yesithando somlilo esiphakathi kukutshayela i-zero frequency, nto leyo ethetha ukuba amandla ombane kunye nangoku anyuka ngokuthe ngcembe ukusuka ku-zero ngexesha lenkqubo yokuqalisa amandla, ngoko ke akukho mpembelelo yangoku kwigridi yamandla. Isekethe yokuqalisa ixhotyiswe ngesekethe yokuqalisa ngokuphindaphindiweyo ngokuzenzekelayo, enokuthintela ukungaphumeleli kwamaxesha athile kunikezelo lwamandla kwaye wenze izinga lokuphumelela lokuqala libe yi-100%. Isekethe yokulandelela i-frequency ithatha iskimu somndilili wesampulu, ephucula amandla okuthintela ukuphazamiseka kwe-inverter. Amacandelo ombane aphambili Iiparamitha zichongiwe ngokulinganisa ikhompyuter, kwaye zinokuchaneka okuphezulu kunye nokuthembeka kunendlela yoyilo lweklasikhi ngokusebenza.

I-2, umthwalo webhulorho ye-inverter yisekethe ye-resonant ehambelanayo

Umthwalo oyintloko webhulorho ye-inverter yesekethe yesithando somlilo esiphakathi yi-parallel resonant circuit ihlanganiswe ne-furnace induction kunye ne-capacitor. Kwisekethe ye-furnace yokufakelwa kwesithando somlilo esiphakathi, i-capacitor yomthamo ofanayo iqhagamshelwe ukunyusa i-voltage ukuze i-voltage ifikelele kwisithando somlilo yi-1500V.

I-3, i-misoperation ayiyi kuchaphazela inkqubo

Ukuhanjiswa kwamandla kunye nokulandelelana kombane wesekethe ephambili kunye nolawulo lwesekethe yesithando somlilo esiphakathi kunye ne-misoperation yomsebenzisi ayiyi kuba nemiphumo emibi kwinkqubo. Imisebenzi ethile yokukhusela yile: ukhuseleko lwesigaba sokusilela; ukhuseleko olungaphaya; ukukhuselwa kombane ogqithisileyo; uKhuseleko olungaphantsi kombane; ukukhuselwa kwamanzi phantsi koxinzelelo lwamanzi. Inkqubo inemisebenzi yokukhusela epheleleyo, kwaye ine-alamu evakalayo kunye nebonakalayo xa kukho nasiphi na impazamo eyenzekayo, kwaye isixhobo siyayeka ukusebenza ngexesha elifanayo.

4, usebenzisa isigaba esithathu esilawulwa ngokupheleleyo kwisilungisi sebhulorho

Inxalenye yokulungiswa kwebhodi yokulawula isithando somlilo esiphakathi ithatha inqanaba lesithathu lokulungiswa kwebhulorho yolawulo olupheleleyo, i-loop yolawulo ithatha isekethe edibeneyo yasekhaya yangoku, kunye nesekethe ye-digital trigger circuit kunye ne-pulse consistency elungileyo kunye nokukwazi ukulwa nokuphazamiseka. I-inverter ithatha ukutshayela i-frequency zero-voltage soft start, kwaye ixhotyiswe ngesekethe yokuqala ephindaphindiweyo, ngaloo ndlela iphucula ukuthembeka kokuqala. Ngethuba nje umgangatho womgangatho womthwalo mkhulu okanye ulingana ne-2.5, izinga lokuphumelela lokuqalisa lingafikelela kwi-100%, kwaye i-frequency tracking circuit ithatha i-avareji yesampula yesampula, ngaloo ndlela iphucula amandla okuthintela ukuphazamiseka kwenkqubo yokuguqula. Ukongezelela, i-automatic inverter θ i-angle adjustment circuit kunye ne-impedance regulator yongezwa kwi-inverter circuit, ekwazi ukuphumeza umbane wamandla phantsi kwayo nayiphi na imeko yomthwalo, ukwenzela ukugcina ixesha, ukugcina umbane, kunye nokuphucula amandla ombane wegridi.
