Kungani Ukuphambuka Kwamapulisi Kuhlela: Ukuvula Amadoda Wezindlela Zokuthola I-Phase-Shifting Rectifier Transformers?

Kuzindustri yesiko samandla, ukudinga kwezindawo, ukusebenza kahle kanye nokuphansi kwezindlela zokuguqula umandla kakhulu ngemva kokuqala. Ngokukodwa kuzindlela zokusebenza zokuguqula kwezimali ezijwayelekileyo kanye nezimali ezikhulu, abasebenzisi bezindawo bayaqaphela izisombululo ezingekelwa ukwephula izimo zokusebenza kanti bapha amandla okusebenza kuzinhlelo. Lokhu kuyindlela ethiwa ngayo ngokuguqula ngemigqa kancane kanye nokuba yini i-transformer yokuguqula enguqula fomu yezindlela kuyindlela ethandwa kakhulu kuzindlela zokusebenza ezinhle.

Izinhlayiya zokulandelana eziyisithupa, ngelokho zibalulekile kakhulu, zingenakho ukungcola okuphezulu kwe-harmonics, okungakwazi ukuthi kuthinte ukuphakama, ukungcola okuphezulu kwekhweletu, nokuthinte izinhlayiya zokusebenza kwezinye izinto zokusebenza. Kodwa fihla lokulandelana lephase, inikela isisindo esibangelwa ngokuhle ngokuvumela ukubalwa okuphezulu kwe-pulse - njenge-12, 18, noma even 24 pulse. Ngokufaka phakathi amawinding amaningi anezindlela ezithile, kuyindlela yokuvumela ukukhanselwa kwe-harmonics eziphansi, kwenza ukukhiqiza iphawu eliphezulu nasekuthuleni. Lokhu kuyindlela yokuthi kungaba yimali kakhulu kuzo zindzwa ezibalulekile njengeyo yendustri yamanzi nenduna, induna, izindlela zokubhola, nezinye izindzwa zokusebenza ngokukhulu, lapho izinseke zokusebenza nokuthula kungase kudingiwe.

Kodwa kanjani lokhu kusebenza? Kuyindlela yokwehla ukulaywa kwamandla kwiimba ezininzi zokubambisa amandla owawusayo kwiindlela ezahlukene. Isibonelo, isisitemu encane yamaphase usesibonelo se-30-degree phase shift phakathi kwezibonelo ezimbili zasekhombisa iziphambano ezingama-6, okuhlela kakhulu ukuncipha oku-5 no-7 okungapheli phakathi kwezinyathelo ezingcono. I-transformer yokubambisa fomu yamaphase yenziwe ngokuchanekileyo ukuba nezindlela zokubandakanya ukuze thekelele kwezikhakha, ngokusebenzisa izindlela ezithile njengeYanbian triangle method ukuthiwa kuneqile yamaphase ngaphandle kokuthilela ukulinganisa kwamandla.

Lesi sakhiwo asithuthukisi kuphela ikhwalithi yefomu lamagagasi kodwa futhi sinciphisa nosayizi nezindleko zezingxenye zokuhlunga ezisezansi. Izakhiwo ezisebenzisa ama-multi-pulse rectifiers zivame ukubona ukwehla okulinganisekayo kokushisa kwe-transformer nokwandisa isikhathi sokuphila kwama-inverters abo, ngenxa yephrofayili ye-harmonic ethuthukisiwe. Ngokombono wohlelo lonke, lokhu kusho isikhathi esincane sokuphumula, izindleko zokugcina eziphansi, nokuhambisana kangcono namakhodi enethiwekhi aqine ngokwengeziwe ahlobene nekhwalithi yamandla kanye nokugqagqana okuphelele kwe-harmonic (THD). Ngamanye amazwi, akukhona nje ukuthuthukiswa kobuchwepheshe - kuwukutshala imali okuhlelekile ekusebenzeni kahle kwesistimu.

Ezinkampanini ezisebenza ngaphansi kwamaphrofayli omthwalo afunwa kakhulu noma ezindaweni lapho ukuhlanekezelwa kwamandla kagesi kungaba nemiphumela ebizayo, ukukhetha ukucushwa kwesiguquli esifanele kubalulekile. I-transformer yokulungisa izigaba ayigcini nje ngokuhlangabezana nemininingwane, kodwa ixazulula izinkinga zangempela. Futhi uma kuziwa emisebenzini emikhulu, njengama - thermal power plant noma amapulatifomu asolwandle, lezo zinkinga zanda ngokushesha. Yingakho amakhasimende ethu amaningi asebenza isikhathi eside eqhubeka ethembela ezixazululweni ezenziwe ngezifiso ze-multi-pulse ukuze ahlangabezane nezidingo zawo eziqondile zokuqondisa amandla, kunokuba aneliswe imishini ejwayelekile.

Njengoqoqwa onemfundo ephakeme kanye nezinhlelo zokusebenza, sizazi ukuthi kuyindlela yokulawulwa kahle phakathi kwekhuba lokusebenza okuphezulu kanye nokusebenzisa okuyilandelweyo. Ngamanye amaphase-shifting rectifier transformer esenza, asikhululwe kuphela ngokuzenzakalelayo ngokushesha lekhesi lekhalayikho kodwa futhi kuthunyelwe kuzindlela zokusebenza kanye nezimo zokulinganisa kweqoqwa lako. Lapho kungaba ngokuvuselela kweqoqwa elilodwa noma ukubekwa kweqoqwa entsha ngokuphela, ukuthunyelwa kwehlelo lekhalayikho le-rectifier transformer elandelweyo kwiqoqwa lako lokusebenza kungakhiwa amaphetho amaningi owawelela ngaphezulu kwesicathami sokusebenza.

Emakethe lapho ukuthembeka kwamandla nekhwalithi yamandla kungokuhluka okuyinhloko, i-transformer ye-phase-shifting rectifier akuyona nje ingxenye - inzuzo yokuncintisana. Xhumana nathi namuhla ukuze uthole ukuthi izixazululo zethu ezinamazinga amaningi zingayithuthukisa kanjani iphrojekthi yakho ngobuchwepheshe obuqinisekisiwe nokusekelwa okwenziwe ngezifiso okunganikezwa kuphela umkhiqizi onolwazi.
