I-Harmonics ichaphazela i-IT, iinkqubo zonxibelelwano / zebhanki ngeendlela ezimbini: ukuqhuba kunye nemitha.Ubume bothumelo bubhekisa kumbane we-harmonic ongeniswe kuthungelwano lwenkqubo yonikezelo lwamandla ngemithombo yangoku ye-pulse efana nabaguquli.Imeko yomthombo we-radiation kukuba imisinga ye-harmonic ifakwe kwinkqubo yonxibelelwano.Njengoko kukhankanyiwe ngasentla kwingcaciso, “Injongo yolu xwebhu kukunciphisa eyona ndlela yombane yeharmonic kwinkqubo yonikezelo lwamandla ukuya kwinqanaba (inqanaba lokuguquguquka) elingayi kubangela iziphumo ezinobungozi kwisixhobo esibuthathaka.Iziphumo eziqhelekileyo zobuntu ze-harmonics ubukhulu becala zezeharmonics Impembelelo yamaza akhoyo kunye neempawu zokuphazamiseka kumbane wokusebenza we-harmonic obangelwa yisoftware yenkqubo yothumelo.
Umonakalo wobunjineli bamandla eharmonics kwigridi yamandla ixhomekeke kumonakalo wombane osebenzayo kumatshini kunye nezixhobo ezikwigridi yamandla, oko kukuthi, umbane osebenzayo we-harmonic udlula inqanaba oomatshini kunye nezixhobo ezinokuthwala.Iqela lonikezelo lombane linoxanduva lokubetha kwamandla ombane osebenzayo ngoku wothungelwano lonikezelo lwamandla, kwaye umsebenzisi wamandla unoxanduva lokwazisa i-harmonic yangoku yesoftware yenkqubo.
Ukuze kuncitshiswe umonakalo we-harmonics kunikezelo lwamandla kunye nenkqubo yokuhambisa, ingcamango esisiseko kukuqala ngomthombo we-harmonic, zama ukuphepha i-harmonic yangoku ejikeleze umthombo we-harmonic, kwaye emva koko unciphise i-voltage ye-harmonic.Indlela yokuphepha umonakalo wangoku we-harmonic kukufaka i-AC filter, enokuthi ithintele ngokufanelekileyo i-harmonic current, ukunciphisa ukuguquguquka kumbane osebenzayo wegridi yamandla, kunye nokuphucula umgangatho wokuhanjiswa kwamandla kunye nokusabalalisa.Ukongeza, inokusebenzisa ngokuguquguqukayo ukusebenza okuphezulu komthwalo wamandla, kwaye ubomi benkonzo bude.Ukongeza, icebo lokucoca libonelela ngomthwalo we-capacitive reactive, onesiphumo esithile sembuyekezo yamandla asebenzayo, ngaloo ndlela siphucula amandla enkqubo.Ngokubhekiselele ekubeni i-loop ephambili ibandakanya izixhobo zomthombo, izihluzi zinokwahlulwa zibe zizihluzi ezisebenzayo kunye nezihluzo ze-passive.
Ngomkhondo wophuhliso lwetekhnoloji yolwazi, unxibelelwano/ishishini letyala, ukuze kuhlangatyezwane neemfuno zokusebenza zegumbi lekhompyuter eliphambili lamaziko amakhulu kunye naphakathi, umthamo wesicelo semithwalo ye-harmonic efana nokuhanjiswa kombane kwisixhobo sokuhambisa amandla. Isoftware yenkqubo yethekhnoloji yolwazi, unxibelelwano/amaziko emali yandisiwe kakhulu.Imithombo ephambili ye-harmonic ye-low-voltage power distribution system ye-technology yolwazi, unxibelelwano / amaziko emali abandakanya ukunikezelwa kwamandla e-UPS, i-transformer yamandla, i-air conditioner yokuguqulwa kwamaza, njl njl iphezulu ngokubanzi.Xa inani elipheleleyo lokuphazamiseka kwe-harmonic i-THDi yangoku idlula i-50% (ngokubanzi ngaphezu kwe-30%), i-5, i-7, kunye ne-11 i-harmonics I-curonics yangoku inzima, ngamanye amaxesha iqulethe ngaphezu kwe-3 harmonics.
Ixabiso lomsebenzisi woLawulo lweHarmonic
Ukuphucula ukuthembeka kweenkqubo zokunxibelelana kwabathengi kunye nesoftware yenkqubo yezixhobo zokusasaza amandla, ukwandisa ubomi benkonzo yezixhobo zonxibelelwano lwabathengi kunye nobunjineli bamandla;ukuphucula umgangatho wothumelo lweempawu zedatha yonxibelelwano, ukuqinisekisa konke ukuhanjiswa okuqhelekileyo kweempawu zedatha yonxibelelwano kunye nezalathi zokusebenza zezixhobo zonxibelelwano;ukuphelisa iingozi eziguquguqukayo zoKhuseleko ezinjengokushisa ngokugqithiseleyo kwezixhobo zombane, ukufudumeza ngokugqithiseleyo kweentambo zobonelelo lombane, ukucuthwa komthamo ophetheyo ngoku, kunye nelahleko yesakhelo samaza ombane okubangelwa kukuntlitha kwemisinga yezixhobo zombane ezifana nombane we-UPS;ukwandisa ukusetyenziswa kwamandla kwe-air-conditioning ephakathi kunye nezinye izixhobo endlwini, kunye nokuphucula inkqubo Isici samandla sesofthiwe sifezekisa injongo yokonga amandla kunye nokunciphisa ukukhutshwa.
Iingxaki onokudibana nazo?
1. Izixhobo zangoku zembuyekezo yamandla asebenzayo azikwazi ukusebenza ngokuqhelekileyo okanye zihlala zivutha;
2. Kwiinkqubo zonxibelelwano, ii-harmonics ziphazamisa iinkqubo zonxibelelwano ezikufutshane.Ingxolo encinci, imbi kakhulu umgangatho wonxibelelwano, ikhompyuter ayiyi kusebenza ngokufanelekileyo, kwaye ubunzima obukhulu, ulwazi luya kulahleka, lubangela ukuba inkqubo iphazamiseke.
3. I-relay yokukhusela ayisebenzi okanye ayisebenzi kakuhle, isixhobo sokulinganisa sombane asilinganisi ngokuchanekileyo, kwaye iimveliso ze-elektroniki ezichanekileyo ziya kuchaphazeleka kakhulu okanye zonakaliswe.
Isisombululo sethu:
1. Sebenzisa izixhobo zokucoca i-Hongyan passive filter ukubonelela ngeshaneli ephantsi-impedance ye-harmonics yefrikhwensi ethile, kwaye ususe i-harmonics ukufezekisa iziphumo zokuchasana kwe-harmonic kunye nembuyekezo yamandla asebenzayo.
2. Sebenzisa isihluzo esisebenzayo i-Hongyan APF ukulawula i-harmonics, kunye nesixhobo sembuyekezo yokhuseleko olusisigxina ukubuyisela amandla asebenzayo enkqubo, ukuze umxholo we-harmonic kunye namandla enkqubo inokuhlangabezana nemigangatho yenkampani yethu.
3. Isihluzo esisebenzayo i-Hongyan APF yamkelwa, ininzi ye-capacitors yesihluzo esisebenzayo isusa i-harmonic filter, kwaye inxalenye ye-capacitor ihlawulela amandla asebenzayo, iphucula amandla ombane, kwaye ilawula ngokufanelekileyo i-harmonics kunye namandla asebenzayo enkqubo. .
