Umthelela Wama-High Voltage Transformers Kukhwalithi Yamandla

Ama-voltage aphezulu adlala indima ebalulekile ekusabalaliseni nasekudluliseni amandla, abe nomthelela kwikhwalithi yamandla ngezindlela ezahlukene. Ukuqonda imiphumela yama-voltage aphezulu kukhwalithi yamandla kubalulekile ukuze kuqinisekiswe ukwethembeka nokusebenza kahle kwezinhlelo zikagesi. Kulesi sihloko, sizohlola umthelela wama-voltage aphezulu kwikhwalithi yamandla futhi sixoxe ngezinyathelo ezingathathwa ukuze kuncishiswe izinkinga ezingaba khona.

Izisekelo zama-High Voltage Transformers

Ama-voltage aphezulu ayingxenye ebalulekile ohlelweni lokudluliswa kwamandla kagesi kanye nokusabalalisa. Asetshenziselwa ukukhuphula i-voltage yokudluliswa kwebanga elide bese ewehlisa ukuze asatshalaliswe kubasebenzisi bokugcina. Lawa ma-transformer ajwayele ukuklama ukuphatha ama-voltages asukela ku-69 kV kuya ku-500 kV noma ngaphezulu. Ama-voltage aphezulu aqukethe ama-windings ayisisekelo kanye nesesibili, i-core, nezinto zokufakelwa. Umnyombo uvamise ukwenziwa ngezinto ezikwazi ukungena kalula njengensimbi ye-silicon ukuze kuncishiswe ukulahleka kwamandla futhi kukhuliswe ukusebenza kahle.

Umsebenzi oyinhloko wesiguquli se-voltage ephezulu ukudlulisa amandla kagesi ukusuka kwesinye isekethe kuye kwenye ngokusebenzisa induction kagesi. Uma i-alternating current (AC) igeleza endaweni yokusonta eyinhloko, idala inkambu kazibuthe eshintshayo engenisa i-voltage ekujikeni kwesibili. Le nqubo ivumela ukudluliswa kwamandla kagesi ngendlela ephumelelayo ebangeni elide.

Ama-voltage aphezulu abalulekile ekugcineni ukuqina nokuthembeka kwamagridi kagesi. Kodwa-ke, zingaphinda zibe nomthelela omkhulu kukhwalithi yamandla, zithinte izici ezifana nokulawulwa kwamandla kagesi, ukuhlanekezela kwe-harmonic, nokusebenza kahle.

Imithelela yama-High Voltage Transformers ku-Voltage Regulation

Ukulawulwa kwamandla kagesi kuyisici esibalulekile sekhwalithi yamandla, njengoba kuqinisekisa ukuthi amandla kagesi anikezwa amandla kagesi ahlala ngaphakathi kwemikhawulo eyamukelekayo. Ama-voltage aphezulu adlala indima ebalulekile ekulawuleni amandla kagesi ngokunyusa noma ukwehlisa i-voltage njengoba kudingeka ekudluliselweni nasekusabalaliseni. Kodwa-ke, izinto ezifana ne-transformer impedance, ukuguquguquka komthwalo, nezimo zesistimu zingathinta ukulawulwa kwamandla kagesi.

Enye indlela ama-voltage angu-high voltage angathinta ngayo ukulawulwa kwe-voltage iwukwehla kwe-voltage nokuguquguquka. Uma umthwalo uxhunywe ekungeneni kwesibili kwe-transformer, i-voltage kumatheminali okulayisha ingase yehle ngenxa yokuphazamiseka kwe-transformer kanye nemigqa yokudlulisa. Lokhu kungaholela ekushintsheni kwamandla kagesi okungase kuthinte ukusebenza kwezinto ezibucayi zikagesi.

Enye inkinga ehlobene nokulawulwa kwamandla kagesi ukungalingani kwe-voltage. Imithwalo engalingani exhunywe ekujikeni kwesibili kwe-transformer ingabangela ukusabalalisa kwamandla kagesi okungalingani kuzo zonke izigaba ezintathu, okuholela ekuhlukeni kwamandla kagesi kanye nokulimala okungenzeka emishinini. Ama-voltage aphezulu kufanele aklanywe futhi asetshenziswe ukuze kuncishiswe le miphumela futhi kugcinwe ukulawulwa kwamandla kagesi okuzinzile.

Umthelela wama-High Voltage Transformers ekuhlanekezweni kwe-Harmonic

I-Harmonics iwukuhlanekezela okungekona komugqa kwe-waveform ye-AC eyisisekelo, ngokuvamile okubangelwa ukuba khona kwemithwalo engaqondile efana nemishini yamandla kagesi. Ama-voltage aphezulu angakwazi ukufaka isandla ekuhlanekeni kwe-harmonic ngokusebenzisa izici ezifana nokugcwala kwe-core, i-magnetizing current, nokuxhumeka kwe-transformer.

Ukugcwaliswa kwe-Core ku-voltage ephezulu ye-voltage kungaholela ekwandeni kokuqukethwe kwe-harmonic ohlelweni. Lapho i-flux magnetic in the core ifinyelela emazingeni okugcwala, i-transformer ingase iqale ukukhiqiza ama-harmonics aphezulu, angathinta ikhwalithi yamandla nokusebenza kahle kwesistimu.

I-Magnetizing current, edingekayo ukuze kusungulwe i-flux magnetic in the core of transformer, ingaba nomthelela ekuhlanekeni kwe-harmonic. I-waveform yamanje eyenza kazibuthe ingase ingabi esigabeni ne-voltage waveform, okuholela kumagagasi e-harmonic angathinta ikhwalithi yamandla iyonke yesistimu.

Ukuxhumeka kwe-Transformer, okufana nokulungiselelwa kwe-delta ne-wye, kungase futhi kube nomthelela ekuhlanekeni kwe-harmonic. Ukukhethwa kokuxhumeka kwe-transformer kungaba nomthelela ekutheni ama-harmonics asatshalaliswa kanjani futhi ancishiswe ngaphakathi kwesistimu kagesi. Ukukhetha okufanele nokuklama kokuxhumeka kwe-transformer kubalulekile ekunciphiseni umthelela we-harmonics kukhwalithi yamandla.

Ukucatshangelwa Ukusebenza kahle kwama-High Voltage Transformers

Ukusebenza kahle kuyisici esibalulekile ekudluliselweni nasekusabalaliseni amandla, futhi ama-voltage aphezulu adlala indima ebalulekile ekuqinisekiseni ukudluliswa kwamandla kagesi ngendlela efanele. Ukulahleka kwe-Transformer, okuhlanganisa ukulahlekelwa kwethusi, ukulahlekelwa okuyisisekelo, nokulahlekelwa okungahambi kahle, kungaba nomthelela ekusebenzeni kahle okuphelele kwesiguquli samandla kagesi aphezulu.

Ukulahleka kwe-Copper, okwaziwa nangokuthi ukulahleka kwe-I2R, kwenzeka kuma-windings we-transformer ngenxa yokumelana kwama-conductor. Lokhu kulahlekelwa kwanda ngesikwele somthwalo wamanje futhi kungathinta ukusebenza kahle kwe-transformer. Ukuklama okufanele kanye nokukhetha kwezinto ezibonakalayo kungasiza ukunciphisa ukulahlekelwa kwethusi futhi kuthuthukise ukusebenza kahle kwe-transformer jikelele.

Ukulahlekelwa okuyinhloko, okuhlanganisa i-hysteresis kanye nokulahlekelwa kwamanje kwe-eddy, kwenzeka ezintweni eziyinhloko ze-transformer ngenxa yezinqubo ze-magnetization kanye ne-demagnetization. Lokhu kulahlekelwa kungaba nomthelela ekusebenzeni kahle kwe-transformer futhi kube nomthelela ekukhiqizeni ukushisa. Ukusebenzisa izinto eziyinhloko zekhwalithi ephezulu nokuthuthukisa umklamo kungasiza ukunciphisa ukulahlekelwa okuyinhloko futhi kuthuthukise ukusebenza kahle kwe-transformer.

Ukulahlekelwa okulahlekile, okubandakanya ukulahlekelwa ngenxa ye-eddy currents ezicini zesakhiwo kanye nezinto zokufakelwa, kungase futhi kuthinte ukusebenza kahle kwe-high voltage transformer. Ukunciphisa ukulahlekelwa okunhlanhlatha ngokusebenzisa idizayini efanele kanye namasu okwakha kubalulekile ukuze kukhuliswe ukusebenza kahle kwe-transformer nokunciphisa ukumosheka kwamandla.

Izinyathelo Zokuthuthukisa Ikhwalithi Yamandla Kuma-High Voltage Transformers

Ukubhekana nomthelela wama-voltage aphezulu kwikhwalithi yamandla kudinga indlela enezici eziningi ecubungula izici ezifana nokuklama, ukunakekelwa, nokuqapha. Izinyathelo ezimbalwa zingathathwa ukuze kuthuthukiswe izinga lamandla kuma-voltage aphezulu futhi kuncishiswe izinkinga ezingaba khona.

Isinyathelo esisodwa esibalulekile siwukukhetha izinto zekhwalithi ephezulu kanye nezingxenye zedizayini ukuze kuncishiswe ukulahlekelwa nokwandisa ukusebenza kahle. Lokhu kufaka phakathi ukusebenzisa izinto eziwumgogodla ezikwazi ukuvumeleka kakhulu, izikhondatha ezimelana kancane, nezinto ezithuthukisiwe zokufaka ugesi ukuze kuthuthukiswe ukusebenza kwama-voltage aphezulu.

Ukugcinwa nokuqapha okufanele nakho kubalulekile ukuze kuqinisekiswe ukusebenza okuthembekile kwama-voltage aphezulu kanye nokugcina izinga lamandla. Ukuhlola okuvamile, ukuhlola, nokunakekelwa okuvimbelayo kungasiza ekuhlonzeni izinkinga ezingaba khona futhi kuvimbele ukwehluleka okungaba nomthelela kwikhwalithi yamandla.

Ukusebenzisa izinhlelo ezithuthukisiwe zokuqapha nokulawula kunganikeza ukubonakala kwesikhathi sangempela ekusebenzeni kwama-voltage aphezulu futhi kunikeze amandla izinyathelo zokubhekana nezinkinga ezingaba khona zekhwalithi yamandla. Lokhu kufaka phakathi ukusetshenziswa kwezinzwa, ubuchwepheshe bokuqapha okukude, nezinhlelo zokulawula ezihlakaniphile ukuze kuthuthukiswe ukusebenza kwe-transformer kanye nokukhulisa ikhwalithi yamandla.

Kafushane, ama-voltage aphezulu anomthelela omkhulu kukhwalithi yamandla ezinhlelweni zikagesi, athonya ukulawulwa kwamandla kagesi, ukuhlanekezela kwe-harmonic, nokusebenza kahle. Ukuqonda imiphumela yama-voltage aphezulu kukhwalithi yamandla nokusebenzisa izinyathelo zokuthuthukisa ukusebenza nokuthembeka kubalulekile ukuze kuqinisekiswe ukuzinza nokusebenza kahle kwamagridi kagesi. Ngokucabangela izici ezifana nokuklama, ukugcinwa, nokuqapha, umthelela wama-voltage aphezulu kwikhwalithi yamandla ungabhekwana ngokuphumelelayo ukuze kusekelwe ukusebenza okuthembekile nokusebenza kahle kwezinhlelo zikagesi.
