Umphakeli weyunithi yempendulo ukukhumbuza ukuthi iziguquli zefrikhwensi ziyimpahla yokutshala imali embonini yamandla kagesi, ikakhulukazi esetshenziselwa ukonga amandla nokuthuthukisa izinqubo zokukhiqiza. Kusenezici ezithile ezingaqinisekile enqubweni yayo yesikhathi esizayo yokuthuthukiswa kwemakethe. Ama-Frequency converters, njengamathuluzi okonga amandla kanye nokulawula isivinini samamothoni, asetshenziswa kabanzi kwezensimbi, amandla, ukuhlinzekwa kwamanzi, uphethiloli, amakhemikhali, amalahle neminye imikhakha. Ukuhlaziywa kwemakethe yabo kungokulandelayo:
1. Imboni ye-Metallurgical:
Ukusetshenziswa kwama-frequency converters emsebenzini we-metallurgical ikakhulukazi kuhlanganisa izigayo eziginqikayo, imishini yokuphotha, izifeni, amaphampu anodaka, njll. kushidi nocingo, ngenhloso eyinhloko yamamotho ezonga amandla.
2. Imboni yamandla kagesi:
Umthamo wokuphehla ugesi waseChina ukleliswe endaweni yesibili emhlabeni, isibili ngemuva kwe-United States. Imboni yamandla nayo ingenye yezindawo ezibalulekile zokusetshenziswa kwemikhiqizo yokuguqula imvamisa. Ngokombono wenqubo yokulawula ehlotshaniswa neziguquli zemvamisa ezimbonini zamandla ashisayo zase-China, izisetshenziswa zokudlulisa umoya, amalahle, amanzi, i-slag, nesistimu yokukhipha umoya konke kulungele ukusetshenziswa kweziguquli zefrikhwensi. Phakathi kwazo, ngaphandle kwesistimu yamalahle (umshini wokukhipha i-powder, i-feeder yamalahle), ezinye izinhlobo ezine zezinhlelo zilayishwa ikakhulukazi abalandeli namaphampu amanzi. Imikhiqizo ye-frequency converters isetshenziselwa ngokuyinhloko ukuguqula amalahle, impushana, amanzi, njll., ukuze ivumelane nezinguquko zomthwalo futhi ekugcineni ifinyelele inhloso yokonga amandla kanye nokwenza ngcono ubuchwepheshe bokulawula. Zibaluleke kakhulu ukongiwa kwamandla, ukunciphisa ukusetshenziswa, ukunciphisa ukungcola, ukuphepha, nokusebenza okuzinzile kwezitshalo zamandla ashisayo.
3. Ukunikezwa kwamanzi:
Uhlelo lokuhlinzeka ngamanzi kanye ne-drainage, uhlelo lokuhlanza indle, njll kuphrojekthi ehlanganyelwe. Lawa madivaysi ngokuyinhloko ama-turbines omoya, amaphampu amanzi, nemithwalo yezimoto. Umthelela wokonga amandla wokusebenzisa iziguquli zefrikhwensi yamandla kagesi aphezulu uvelele kakhulu, ngokuvamile ukuzuza ukonga amandla okungaba ngu-30%.
4. Imboni kawoyela negesi yokumba kanye nokukhiqiza:
Kusukela ngo-2004, imboni kawoyela negesi yokumba kanye nokukhiqiza ibe senkathini yokuchuma okukhulu, nezinkampani zikawoyela ezintathu ezinkulu zaseChina zigcine ukukhuphuka okungaphezu kwama-20% ezindlekweni zokuhlola. Muva nje, i-China yenze uchungechunge lwezinsiza ezibalulekile ezitholakele emkhakheni kawoyela negesi, njengesizinda sikawoyela i-Hebei Jidongnanbao esinendawo yokugcina amathani ayizigidi eziyizinkulungwane eziyi-1 kawoyela ongahluziwe, insimu yegesi yaseSichuan Longgang enendawo egciniwe engama-cubic metres ayizigidi eziyizinkulungwane ezingama-500, kanye nesifunda se-12 seTahe esinendawo kawoyela e-Tahe eseduze nendawo kawoyela eyizigidi eziyizinkulungwane ezingama-20 eXinji. amafutha. Kulinganiselwa ukuthi ukutshalwa kwezimali ekuhloleni uwoyela negesi yizinkampani ezinkulu zikawoyela kuzoqhubeka nokuthuthuka eminyakeni ezayo. Ama-frequency converters asetshenziswa kakhulu embonini yezimayini zikawoyela, ikakhulukazi amamotor ezinhlobo zomthwalo njengemishini yokukhipha uwoyela (imishini yokungqongqoza), amaphampu omjovo wamanzi, amaphampu angaphansi kwamanzi, amaphampu okudlulisa uwoyela, ama-gas compressors, njll., ngenhloso yokonga amandla ezinjini.
5. Imboni ye-Petrochemical:
Imboni ye-petrochemical iwumgogodla wokuthuthukiswa komnotho kazwelonke. Ama-frequency converters asetshenziswa ngokuyinhloko kumaphampu ahlukahlukene, ama-compressor, namaphrojekthi okwabelwana ngawo ekucutshungulweni kwe-petroleum (ukucwengwa) ukuze kuzuzwe amandla okonga namandla okulawula inqubo.
6. Imboni yezinto zokwakha:
Imboni yezinto zokwakha iyimboni yolwazi ebalulekile e-China, futhi imikhiqizo yayo ihlanganisa izigaba ezintathu: izinto zokwakha kanye nemikhiqizo, amaminerali angeyona insimbi nemikhiqizo, kanye nezinto ezintsha ezingezona ezensimbi ezingaphili. Imikhiqizo yeziguquli zefrequency isetshenziswa kakhulu ezintweni ezinjengokuvuthela, ama-crusher, amabhande okuthutha, amafeni akhipha umoya, ama-rotary kilns, njll. embonini yezinto zokwakha. Ngokwezibalo zezinhlangano ezixhumene nazo, cishe amaphesenti angama-70 amandla okukhiqiza usimende eShayina asesimweni sokushisela ama-shaft amakhono aphelelwe yisikhathi kanye nokusetshenziswa okuphezulu kwamandla. Ngokuguqulwa kwesiguquli semvamisa, ukonga amandla ka-10% kuya ku-20% kungafinyelelwa, okungathuthukisa ukulawuleka kwekhwalithi yomkhiqizo. Ngokusho kokuhlaziywa kwe-Dongfang Securities, isidingo sabaguquli bamandla kagesi aphezulu emakethe sizoqhubeka nokukhula ngenani elingaphezu kwama-40% eminyakeni ezayo. Kulinganiselwa ukuthi ngo-2012, amandla emakethe yaseShayina yokuguqula imvamisa ye-high-voltage azofinyelela cishe kuma-yuan ayizigidi eziyizinkulungwane eziyi-8.8, futhi kulinganiselwa ukuthi amandla emakethe yokuguqula ama-frequency azodlula ama-yuan ayizigidi eziyizinkulungwane ezingama-50 eminyakeni eyishumi ezayo. Amandla emakethe yokuguqula amandla kagesi aphezulu yaseChina makhulu kakhulu. Njengamanje, izinga lokusebenzisa ama-inverter ane-voltage ephezulu e-China lingaphansi kwama-30%, kanti emazweni athuthukile selifinyelele ku-70% Ngenxa yokuthi ukufakwa kwe-frequency converter kungafinyelela ukonga amandla afanayo angama-30%, ukusetshenziswa kweziguquli ze-high-voltage frequency kuyasheshiswa endaweni yezomnotho enekhabhoni ephansi. Ngo-2008, imali yokuthengisa yemakethe ye-inverter yaseChina ephezulu yafinyelela ku-3.4 billion yuan, futhi kulindeleke ukuthi igcine izinga lokukhula elingaphezu kwama-40% eminyakeni emine ezayo. Uma kuphela u-30% wamamotho akhona nasanda kwengezwa afakwa kabusha ukuze alawule isivinini nokongiwa kwamandla, kuzoba nenani elilinganiselwa ezigidini ezingama-70 KW kanye nezi-70000 zomthamo wenxanxathela yezitolo. Eminyakeni eyishumi ezayo, umthamo wenxanxathela yezitolo uzodlula amayunithi angama-70000 futhi umphumela uzodlula ama-yuan ayizigidi eziyizinkulungwane ezingama-50.
7. Imboni yamalahle:
I-China iyizwe elikhulu kunawo wonke emhlabeni elikhiqiza amalahle. Njengemboni yamandla ayisisekelo e-China, imboni yamalahle ibilokhu iyinkampani edinga abasebenzi abaningi. Ukuyiguqula ibe imboni edinga amakhono ajulile futhi siqale indlela entsha yezezimboni, kuyadingeka ukukhuthaza ngamandla amakhono obuchwepheshe obuphezulu, ukuthuthukisa amandla okusebenza kwemishini kanye nezinga lokulawula okuzenzakalelayo. Ikhono lokulawula isivinini sokuguqulwa kwemvamisa lingadlala indima enhle yokonga ugesi ezindaweni zokufukula ezimayini ezisetshenziswa embonini yamalahle. Njengamanje, amazwe athuthukile asebenzise kakhulu ama-frequency converter ukulawula isivinini sezinto zokuthutha amabhande, ukuqala ukulawula amabhande, ukulawula isivinini samafeni (okuhlanganisa amafeni amakhulu okungenisa umoya kanye namanye amafeni okungenisa umoya), kanye nokulawula isivinini sepompo yamanzi. Ngaphezu kokuthuthukisa umsebenzi wokudlulisa, into ebaluleke kakhulu yokuhlomisa injini ngesiguquli semvamisa emishinini engenhla ukonga amandla.
Kusukela ezintweni ezingenhla, kungabonakala ukuthi abaguquli befrikhwensi banezinhlobonhlobo zezinhlelo zokusebenza ezimbonini ezihlukahlukene zokulawula izimboni, futhi isidingo sabo semakethe siphezulu kakhulu. Kungabonakala ukuthi amandla okuthuthukiswa kwesikhathi esizayo makhulu kakhulu.
