Nidaamka korontada ee isbitaalku waxaa iska leh nidaamka dadweynaha, kaas oo ah unugga dammaanadda bixinta korontada ee dhammaan deegaannada.Naqshadeynta dhismaha isbitaalku wuxuu inta badan qaataa nooc badh-dhexe ah, culeyska korantadana waxaa iska leh qeybta culeyska.Noocyada ugu muhiimsan ee korontada waxaa ka mid ah: nidaamka iftiinka, nidaamka qaboojinta, nidaamka awoodda caafimaadka, nidaamka nalka degdegga ah.
Nidaamka nalka iyo qaboojiyaha ayaa ah culeysyada ugu weyn ee noocyada kala duwan ee isticmaalka korontada isbitaalka, kaas oo soo saari doona jawaab celin iswaafajin oo ballaaran oo ku saabsan xadhkaha korontada ee isbitaalka inta lagu jiro isticmaalka.Sababo la xiriira isticmaalka noocyada cusub ee koronto sida mishiinka raajada, mashiinka resonance magnetka MRI, mashiinka CT, iwm., isticmaalka sahayda korantada wareejinta, UPS aan kala go' lahayn iyo tiro kale oo badan oo culeysyo aan toos ahayn, waxay sidoo kale soo saaraan jawaab celin iswaafaqsan shabkada korantada.
Cisbitaalku waxa uu leeyahay isticmaalka koronto heerkiisu sareeyo, qalabka nidaamkuna waa badbaado oo la isku halayn karo oo ah qodobka koowaad.Sababo la xiriira isticmaalka ballaaran ee culeyska aan tooska ahayn, iswaafajinta dabeecadda ee nidaamka 3aad, 5aad iyo 7aad ayaa inta badan lagu soo saaraa shabakadda korontada ee isbitaalka.Harmonics waxay si toos ah u saameeyaan hawlgalka xasilloon ee qalabka caafimaadka saxda ah, iyo ururinta 3 harmonics ee khadka dhexdhexaadka ah waxay keenaysaa kulaylka khadka dhexe, taas oo khatar gelinaysa hawlgalka badbaadada leh ee shabakada korontada ee isbitaalka.
2. Qeexida iyo abuurista harmonics
Qeexida harmonics: kala goynta taxanaha Fourier ee tirada sinusoidal ee aan tooska ahayn ee xilliyeedka, marka lagu daro helitaanka isla qayb la mid ah inta jeer ee aasaasiga ah ee korontadu, laakiin sidoo kale qaybo taxane ah oo ka weyn isku dhufashada isku dhafka ah ee inta jeer ee aasaasiga ah ee awoodda grid, qaybtan ka mid ah korontada waxaa loo yaqaan harmonics.
Generation of harmonics: Marka hadda uu ku dhex qulqulo culeyska, waxaa jira xiriir aan toos ahayn oo la leh korantada culeyska, taas oo sameysa hadda aan sinusoidal ahayn, taas oo keenta is-waafajin.
3. Harm of harmonics
1) Harmonics waxay keentaa koronto aan habooneyn iyo shilalka kala go'a qalabka ee ay sababto si xun u shaqeynta ama diidmada ilaalinta iyo aaladaha otomaatiga ah, taasoo keentay khasaare badan oo dheeraad ah.
2) Kordhinta inta jeer ee hadda iswaafajinta waxay keentaa saameyn cad oo maqaarka ah, taas oo kordhisa caabbinta fiilooyinka fiilooyinka korontada iyo xadhkaha qaybinta, waxay kordhisaa luminta khadka, waxay kordhisaa kulaylka, da'da hore ee dahaarka, waxay yareysaa nolosha, waxay keentaa dhaawac. wuxuuna u nugul yahay cilad wareeg gaaban oo dhulka ah, samaynta khatar dab ah.
3) In uu kiciyo dhawaaqa korantada, u horseeda koronto is-waafajisa iyo koror xad dhaaf ah, sababto shilal halis ah, dhaawaca magdhowga capacitor-ka iyo qalabka kale ee korontada
4) Harmonics waxay saameeyaan shaqada caadiga ah ee qalabka kala duwan ee korontada.Waxay keentaa khasaare dheeraad ah iyo kulayl badan ee matoorrada asynchronous iyo transformers, oo ay ku xigto gariir farsamo, buuq iyo xad-dhaaf ah, yaraynta waxtarka iyo ka faa'iidaysiga, iyo soo gaabin nolosha adeegga.
5) Farogelinta isgaadhsiinta ku dhow, qalabka elektarooniga ah ama kan tooska ah, ama xitaa ka dhigaya mid aan awoodin in uu si caadi ah u shaqeeyo.
4. Nidaamka shaandhaynta
Cisbitaalka dhexe ee Shaanxi waa cisbitaal heer labaad ah oo heer qaran ah oo leh qalab caafimaad oo horumarsan iyo jawi cisbitaal oo aad u wanaagsan.Shaqaaleheena xirfadlayaasha ah iyo kuwa farsamada ayaa isbitaalku u wakiishay marxaladii hore si ay u cabbiraan tayada korantada korantada hoose ee cisbitaalka.Wadarta heerka qallooca hadda ee shabagga korantada ee cisbitaalka waa 10%, inta badan waxaa loo qaybiyaa hab-raaca sifada ee 3aad, 5aad iyo 7aad.Marka loo eego natiijooyinka baaritaanka, shirkadeena waxay u habeysay awood 400A qalab filter firfircoon oo loogu talagalay isbitaalka, oo lagu rakibay dhinaca korantada korantada hooseeya, adeegsiga daaweynta dhexe ee xakameynta iswaafajinta.
5 Filter Firfircoon (/ 690v-active-power-filter-product/)
5.1 Hordhaca Alaabta
Filter Power Firfircoon (/noker-3-phase-34-wire-active-power-filter-apf-ahf-for-dynamic-harmonics-compensation-product/) waa nooc cusub oo ah aaladda korantada ee loo isticmaalo in si firfircoon loo xakameeyo is-waafajinta magdhow tamarta falcelinta, taas oo magdhow karta harmonics iyo isbeddelka tamarta falcelinta ee cabbirka iyo inta jeer.
5.2 Mabaadi'da Shaqada
Hadda culeyska waxaa lagu ogaadaa CT-ga dibadda ah waqtiga dhabta ah, iyo qiimaha isku midka ah waxaa lagu xisaabiyaa gudaha DSP.Iyada oo loo marayo calaamadda PWM ayaa loo diraa IGBT, rooggu wuxuu soo saaraa hadda iswaafajiya oo u dhigma culeyska culeyska iyo jihada ka soo horjeeda ee korantada korantada si loo demiyo is-waafajinta oo loo gaaro ujeedada nadiifinta korantada.
6 .La socodka iyo falanqaynta xogta xakamaynta harmonics ee isbitaallada
Golaha wasiirada APF
Xogta APF(/harmonics-compensation-200400v-active-harmonic-filter-ahf-module-triple-phase-product/) magdhowga iswada leh ee cisbitaalka waxaa kormeeray falanqeeyaha tayada awooda CA8336 ee France, iyo xogta tayada awooda ayaa siday u kala horreeyaan loo tijaabiyay labada shuruudood ee hawlgalka APF (magdhow ka dib) iyo xidhidh ( magdhow la'aan), xogtana waa la soo koobay oo la falanqeeyay.
6.1 Cabbirka iyo falanqaynta APFs(/3-phase-3-wire-active-power-filter-400v-75a-apf-panel-product/) xogta gelida iyo saarista
1: Qiimaha wax ku oolka ah ee orodka hadda
2:THDi ka hor inta aan la isku xidhin filterka firfircoon
3:THDi ka dib shaandhada firfircoon ee ku xiran
4:THDi laga bilaabo 1aad ilaa 5aad ka hor inta aan la xidhin shaandhada firfircoon
5: THDi laga bilaabo 1aad ilaa 5aad ka dib marka la isku xiro shaandhada firfircoon
6:THDi laga bilaabo 1aad ilaa 7aad ka hor inta aan la xidhin shaandhada firfircoon
7: THDi laga bilaabo 1aad ilaa 7aad ka dib marka la isku xiro shaandhada firfircoon
Natiijo:
| APF | THDi (wadarta) | THDi (5aad) | THDi (7aad) |
| Kahor inta aysan APF isku xirin | 10% | 9% | 3.3% |
| Kadib isku xidhka APF | 3% | 3% | 0.5% |
Sida ku cad shaxanka kore, xakamaynta iswaafajinta ee cisbitaalka ee AHF Falanqeeyaha tayada awoodda xirfadeed CA8336 ee Faransiiska.Isbarbardhigga xogta ka hor iyo ka dib APF ayaa siday u kala horreeyaan loo tijaabiyey.Ka dib markii aan u isticmaalno APF-ka xakamaynta iswaafajinta, wadarta heerka qallooca ee hadda jira (THDi) ee shabakada korantada cusbitaalka ayaa laga dhimay 10% ilaa 3%, saamayntuna aad ayay muhiim u tahay.
7. Kooban
Nidaamka korontada ee cisbitaalku waa muhiim.Soo saarista qalab koronto oo cusub ayaa wax weyn ka taray tayada iyo tayada caafimaad ee cisbitaalka, sidoo kale waxa ay si fiican u daaweeyeen bukaanada intooda badan.Laakin culayska korontadu waxa kale oo uu keenaa wasakhaynta iswaafajinta.Jiritaanka harmonics waxay waxyeelo u geysataa shaqada caadiga ah ee shabakada korontada ee isbitaalka waxayna saameyneysaa xasiloonida qalabka daaweynta saxda ah.Iyada oo qayb ka ah nidaamka korantada dadweynaha, harmonics waxay kordhisaa isticmaalka korontada ee isbitaallada, taas oo ka soo horjeeda hal-ku-dhigga qaranka ee kor u qaadista ilaalinta tamarta.
Ka dib marka shaandhadayada firfircoon la geliyo shaqada, waxay si weyn u wanaajisaa tayada shabagga korantada ee cisbitaalka, waxay meesha ka saaraysaa khataraha badbaadada, waxay hagaajinaysaa tamarta korantada ee badbaadada iyo nadiifka ah ee qalabka caafimaadka, isla mar ahaantaana waxay tixgelisaa badbaadinta tamarta iyo dhimista isticmaalka.
