Isticmaalka ballaaran ee xawaaraha isbeddelka, servo, ups iyo alaabooyin kale, tiro badan oo harmonics ah ayaa ka soo muuqday shabkada korantada, iyo harmonics waxay keeneen dhibaatooyin tayo leh oo aad u weyn.Si loo xalliyo dhibaatada harmonic ee shabakada korontada, shirkadeena waxay soo saartay saddex heerfiltar firfircoonku salaysan shaandhada firfircoon ee laba-heer ah.
Shaandheeyaha harmonic firfircoonwaxaa si weyn loogu isticmaali karaa shabakadaha qaybinta warshadaha, ganacsiga iyo hay'adaha, sida: nidaamyada korontada, shirkadaha daminta electrolytic, qalabka daaweynta biyaha, shirkadaha petrochemical, xarumaha dukaamanka iyo dhismayaasha xafiisyada, saxda ah shirkadaha elektiroonigga ah, garoonka diyaaradaha / nidaamka korontada ee dekedda, hay'adaha caafimaadka. , iwm. Marka loo eego walxaha kala duwan ee codsiga, codsigafilter awood firfircoonwaxay door ka ciyaari doontaa hubinta isku halaynta korontada, yaraynta faragelinta, hagaajinta tayada alaabta, kordhinta nolosha qalabka iyo yaraynta dhaawaca qalabka.
Harmonic-ka 3-aad ee badi warshadaha semiconductor waa mid aad u daran, badi ahaan sababtoo ah tirada badan ee qalabka sixitaanka weji keliya ee loo isticmaalo shirkadaha.Midda saddexaad ee harmonic waxay ka tirsan tahay isku-dhafka eber ee isku xigxiga, kaas oo leh sifooyinka isu-ururinta khadka dhexdhexaadka ah, taasoo keentay cadaadis xad-dhaaf ah oo ku saabsan khadka dhexdhexaadka ah, iyo xitaa ifafaale shid, kaas oo leh khataro weyn oo qarsoon ee badbaadada wax soo saarka.Harmonics sidoo kale waxay sababi kartaa jebiyeyaasha wareegga inay safraan, dib u dhigaan wakhtiga wax soo saarka.Midda saddexaad ee iswada leh waxay samaysaa wareegga wareegga wareegga waxayna dedejisaa gabowga beddelka.Wasakhowga halista ah ee is-waafajinta waxay si lama-huraan ah u saameyn doontaa waxtarka adeegga iyo nolosha qalabka nidaamka qaybinta korontada.
Inta badan isku xirka dib u habeynta inverter waa codsiga 6 garaaca si loogu beddelo AC una beddelo DC, markaa harmonics-yada la soo saaray waxay u badan yihiin 5, 7, 11 jeer.Khataraha ugu weyni waa khataraha qalabka korontada iyo weecinta cabbirka.Isticmaalkafiltar firfircoonwaxay xal fiican u noqon kartaa dhibaatadan.
Isticmaalkaharmonic firfircoonfilter:
1. Kala shaandhaynta hab-dhaqanka hadda jira, kaas oo si hufan u shaandhayn kara hab-dhaqanka 2-25 jeer ee culayska jira, si shabakadda qaybinta looga dhigo mid nadiif ah oo hufan, isla markaana buuxisa shuruudaha heerka qaran ee jarista shabakadda qaybinta.Shaandheeyaha firfircooni wuxuu si toos ah u aqoonsan karaa isbeddelada culeyska guud iyo is beddelka nuxurka iswaafajinta wuxuuna si deg deg ah ula socon karaa magdhowga, jawaabta 80us ee isbeddelada culeyska, 20ms si loo gaaro magdhow dabagal buuxa ah.
2. Hagaajinta isku dheelitir la'aanta nidaamka, waxay si buuxda u baabi'in kartaa isku dheelitir la'aanta nidaamka ee ay keento harmonics, marka la eego ogolaanshaha awoodda qalabka, waxaa lagu dejin karaa iyadoo loo eegayo isticmaaluhu si loo magdhabo nidaamka taxanaha taban ee aasaasiga ah iyo qaybaha isku xigxiga eber iyo dheelitirnaanta dhexdhexaadka ah ee awoodda falcelinta.
3. Jooji dhawaaqa shabkada korantada, taas oo aan la jaan qaadi doonin shabkada korantada, oo si wax ku ool ah u ekaan karta dhawaaqa shabkada korantada lafteeda inta ay le'eg tahay baaxadda awoodeeda.
4. Hawlaha ilaalinta ee kala duwan, oo leh hadda ka badan, koronto ka badan, korantada, heerkulka sare, cilladda wareegga cabbirka, garaaca hillaaca iyo hawlaha kale ee ilaalinta.
5. Hawlgalka dhijitaalka ah ee buuxa, oo leh mashiinka-mashiinka saaxiibka ah, samaynta hawlgalka fudud, fududahay in la isticmaalo oo la ilaaliyo.
