Ukubukwa Okuphawuleka komkhiqizo: Ukuhlinzekwa kwamandla kagesi we-electrolytic kuyindawo yamandla aphezulu ye-DC eyenzelwe ngqo izinqubo ze-electrochemical. Umsebenzi wayo oyinhloko ukuguqula amandla wezigaba ezintathu i-AC ibe yi-voltage ephansi, ephezulu kakhulu, ezinzile kakhulu, namandla e-DC alungiswayo, ahlinzeka ngamandla aqhubekayo futhi athembekile kwiseli le-electrolytic. Umgomo wayo wokusebenza unjengokulandelayo: Amandla wesigaba esithathu e-AC ahlukaniswe futhi ehlaselwa yi-transformer, bese ulungiswa ku-DC okulungiswayo kusetshenziswa ama-thyristors noma amadivayisi wokushintsha imvamisa ephezulu. Ukulingana kwamanje kutholakala ngokusebenzisa amasu wokuxhuma okufanayo noma ama-modular. Ukunikezwa kwamandla okulungisa i-electrolytic kusetshenziswa kabanzi ku-non-ferrous metal electrolysis (copper, aluminium, zinc, umthofu, manganese, njll.), imboni yamakhemikhali ye-chlor-alkali, i-electrolysis yamanzi yokukhiqiza i-hydrogen, ukukhiqizwa kwe-chlorine nge-electrolysis, negolide…

Ukubuka konke komkhiqizo: Ukuhlinzekwa kwamandla we-DC olulungisiwe nge-voltage kuyivayisi yamandla ekhethekile eguqula amandla e-AC abe yi-amplitude ephezulu D. Ukukhishwa kwamandla kagesi. I-voltage yokukhipha imvamisa isukela kuma-kilolts amaningana kuya emakhulwini ama-kilovolts, ngamandla okukhipha ahlukahluka kusuka kuma-watts angamakhulu amaningana kuya kumashumi ama-kilowatts. Umsebenzi wayo oyinhloko ukuhlinzeka ngamandla azinzile, ephansi we-DC emithwalo edinga ukuchema okuphezulu kwe-DC noma ukuphakelwa. Ngokungafani namandla ajwayelekile we-DC, izinselelo zobuchwepheshe eziyinhloko zokuphakela kwamandla we-DC alungisiwe ama-voltage aphezulu kulele ekwakhiweni kwe-infection enamandla amakhulu, ukulawulwa kokufana kwenkambu kagesi, kanye nokulinganiselwa kwamandla okukhipha okugcinwe. Lapho i-voltage yokukhipha ifinyelela kumashumi ama-kilobolts, ukufakwa komoya akusakwazi ukuhlangabezana nezidingo, futhi kufanele kusetshenziswe ukufakwa kukawoyela.

Ukubuka konke komkhiqizo: Ukuphakelwa kwamandla okuphakeme okuphezulu kwe-DC yidivayisi yamandla aphezulu ye-DC yamandla ‑ opikelelwe ngokukhethekile inqubo ye-electrochemical yezimboni nezinhlelo ezikhethekile zokuncibilikisa. Isici sayo esichazayo yikhono laso eliphakeme kakhulu lokukhishwa kwamanje - ngokujwayelekile kusuka ezinkulungwaneni ezimbalwa ama-amper kuya emakhuli ezinkulungwane zama-ampere- ngenkathi kugcina amandla okukhipha aphansi. Umgomo wayo oyisisekelo wokusebenza imi kanje: Amandla wesigaba se-AC, ngemuva kokuhlukaniswa nokukhishwa phansi yi-transformer, iguqulwe ibe ngumkhiqizo we-DC eguqukayo ngokusebenzisa amadivayisi we-thiyristor noma e-diode rectifier. Okwamanje kusatshalaliswa ngokulinganayo ngamasu wokuxhuma okuphambene noma ama-module‑parallel. Ngokungafani namandla ajwayelekile e-DC, inselelo yezobuchwepheshe eyinhloko yokuhlinzeka kwamandla okulungisa aphezulu akhona ekulawulweni kwamandla kagesi, kepha nge-ultra-ephakeme

Ukubuka konke komkhiqizo: I-cyclical polarity-reversal (i-bipolar) Ukunikezwa kwamandla okulungisa umqhubi kuyindawo ekhethekile yokuhlinzeka kwamandla we-DC ekwazi ukuzenzakalela noma ngokushintsha ngesandla ukukhipha amandla we-DC ngesikhathi sokusebenza. Umsebenzi wayo oyinhloko ukushintsha ngokuzenzakalela i-polarity ye-terminal yokukhipha-ehle futhi ephambene- ngokuya ngomjikelezo wesikhathi noma wokulawula umyalo, ngaleyo ndlela ukufaka umthwalo (njengomsebenzi wokusebenza ethangini le-electroplating) ezimweni ze-anodic kanye ne-cathodic. Lokhu kuhlinzekwa kwamandla kuhloselwe ikakhulukazi izinqubo ze-electroplating ezinezidingo eziqinile zokugqoka ubuningi, ukunamathela, kanye nokufana. Ezinqubweni ezifana ne-cyclic chromium plating yamanje, ukwanda kwe-electro, ukwanda kwe-alkaline womgqomo wethusi, nokuhlupha, Ukushintshana ngezikhathi ezithile i-polarity kungathuthuka ngempumelelo…

Ukubuka konke komkhiqizo: Ukuhlinzekwa kwamandla okushintsha imvamisa ephezulu kwe-IGBT kuyivayisi yokuhlinzeka kwamandla kwe-DC yesizukulwane esilandelayo esebenzisa i-insulate d-gate bipolar transistor (IGBT) njengengxenye yayo yamandla eyinhloko futhi isuselwa kubuchwepheshe obukhulu be-PWM pulse-width modulation. Umgomo oyisisekelo wokusebenza imi kanje: Amandla wezigaba ezintathu e-AC alungiswa futhi ahlangiswe ukukhiqiza amandla ama-DC abushelelezi, okube eseguqulwa kube yi-AC-frequency ephezulu (imvamisa i-10 kHz kuya ku-50 kHz) yi-IGBT egcwele ibhuloho. Ngemuva kokunyuswa phezulu noma phansi nokuhlukaniswa yi-transformer enemvamisa ephezulu, okukhiphayo ekugcineni kulungiswa futhi kuhlungwe ukuhlinzeka nge-DC voltage ezinzile noma yamanje. Uma kuqhathaniswa nezimpahla zamandla zendabuko ezilawulwa yi-thyristor, Ukunikezwa kwamandla okushintsha imvamisa ephezulu kwe-IGBT kwandisa imvamisa yokusebenza kusuka kumvamisa womugqa.

Ukubuka konke komkhiqizo: Uhlelo lokuhlinzeka kwamandla amabanga amade lwe-DC uhlelo lokulethwa kwamandla okukude oludlulisa futhi luthole amandla kagesi we-DC isikhathi eside amabanga ngezintambo zamandla. Uhlelo luqukethe izingxenye ezimbili eziyinhloko: imishini yamahhovisi emaphakathi (iyunithi eseduze) kanye nemishini ekude (iyunithi yokugcina.) Imishini yehhovisi emaphakathi iyanyuka futhi iguqule amandla e-AC noma amandla e- −48V DC avela egumbini lemishini ibe yi-voltage ephezulu DC, okube sekudluliselwa emabangeni amade ngekhebula elihlanganisiwe likagesi noma ikhebula lamandla liye ekugcineni. Ekugcineni, imishini ekude yehlela i-voltage DC ephezulu kuma-voltages ajwayelekile adingwa yimithwalo (njenge-DC 48 V, I-AC 220 V, njll.), ukuhlinzeka ngamandla okuzinzile nokwethenjelwa kwemishini yokuxhumana okukude noma amadivayisi wensimu. Lobu buchwepheshe buyaxazulula

Ukubukwa Okuphawuleka komkhiqizo uhlelo lokuhlinzeka kwamandla amabanga amade i-AC kuyivayisi ekhethekile yokuhlinzeka kwamandla okukude ye-AC eyenzelwe izinhlelo zokusebenza njengakho imigwaqo emikhulu neziteshi eziyisisekelo zokuxhumana. Uhlelo luqukethe izingxenye ezimbili eziyinhloko: iyunithi emaphakathi (umkhiqizo wamandla wokuhlukanisa) kanye neyunithi elikude (ukuguqulwa kwamandla okuhlukanisa). Ngokusebenzisa inqubo yokudlulisa isinyathelo phansi, iyunithi emaphakathi likhulisa amandla e-AC ajwayelekile kusuka egumbini lemishini kuya ku-voltage AC-ranging kusuka kuma-volts angamakhulu ambalwa kuya ngaphezu kwe- amavolts ayinkulungwane. Le AC enama-voltage ephezulu bese idluliselwa emabangeni amade ngezintambo zamandla esizeni esikude, lapho iyunithi elikude liyibeka phansi futhi lilawule ku-voltage ejwayelekile ye-AC edingwa ngamadivayisi wokulayisha (e. g., I-AC 220V), ngaleyo ndlela inikeze amandla we-AC ezinzile futhi athembekile emishinini ekude. Uhlelo lokuphakelwa kwamandla okukude lokuxhumana

Ukubuka konke komkhiqizo: Isigaba esisodwa esiguquguqukayo sokuphathwa kwamandla kagesi yidivayisi yamandla ephezulu ye-AC esebenzisa i-IGBT / PWM pulse ubuchwepheshe bokuguqula ububanzi. Ingaguqula amandla ama-mains (isigaba esisodwa 220 V / 50 Hz) Kukukhipha okumsulwa kwe-sine-wave AC ngamandla kagesi kanye nemvamisa okulungiswa ngokuzimela. Inani layo eliyinhloko lisekhonweni kwalo lokulingisa amandla kagesi namazinga okuvamisa amazwe emhlabeni jikelele (enjalo) njenge-110 V / 60 Hz, 220 V / 50 Hz, 240 V / 50 Hz, njll.), ukuhlinzeka ngendawo yokuhlinzeka kagesi eguquguqukayo futhi ethembekile yokuhlolwa kwe-R & D nokuqinisekiswa kwekhwalithi kogesi kagesi ne-electro egxile kuthunyelwe kwamanye amazwe. imikhiqizo. Ngokungafani nokuhlinzekwa kwamandla okulawulwa okujwayelekile, amandla okukhipha okukhiphayo wesigaba esisodwa sokuphakelwa kwamandla okuguquguqukayo (0
