Guhindura ikirere hakoreshejwe amavuta: Ibisobanuro bya tekiniki n'imiterere y'igishushanyo

Transformer ikoreshwa mu mavuta Ingufu zo gufunga ni ingenzi mu buryo bwo gukwirakwiza ingufu z'amashanyarazi, zigenewe kohereza ingufu z'amashanyarazi neza mu buryo bunoze mu gihe zizewe kandi ziramba. Hasi hari isesengura rirambuye ry'imiterere yazo, ibikoresho, n'amahame y'imikorere, byakozwe hakurikijwe amahame y'inganda n'ibisobanuro bya tekiniki.

Ubushyuhe bwo hejuru bwa transformer itwikirwa muri peteroli burabujijwe kurenza 95 ° C, muri rusange burabujijwe kurenza 85 ° C, uburyo rusange bwo guhitamo transformer zunguruka ibikoresho byo mu rwego rwa A byo gukingira, ubushyuhe ntarengwa bwemewe bwibikoresho byo gukingira ni 95 ~ 105 ° C, mu bipimo by'ubushyuhe bya transformer mu Bushinwa bishingiye ku bushyuhe bwo gukora bwa 40 ° C nk'uko bisanzwe, zunguruka ry'ubushyuhe mpuzandengo bwa gaze buri muri 65 ° C, Izamuka ry'ubushyuhe bw'amavuta yo hejuru kuri gaze rishyirwa neza kuri 55 ° C, bityo zunguruka ririmo igice cy'imbere cya transformer ririmo mu izamuka ry'ubushyuhe bw'amavuta kuri 10 ° C.

Iyo ubushyuhe bwo hejuru bwa transformateur ari 85 ° C, ubushyuhe bwo kuzunguruka ni 95 ° C; Iyo ubushyuhe bwo hejuru ari 95 ° C, ubushyuhe bwo kuzunguruka bugeze kuri 105 ° C, bugeze ku bushyuhe ntarengwa bwemewe bw'ibikoresho byo kuzunguruka. Ubushyuhe bwinshi cyane buzihutisha gusaza kw'ibikoresho byo kuzunguruka, bwihutishe kwangirika kw'amavuta ya transformateur, kandi bugire ingaruka mbi ku buzima bwabyo. Transformateur yo gukwirakwizas, ndetse bigatera impanuka z'umutekano.

Sisitemu ikomeye yo gukwirakwiza amavuta ikonjeshwa n'umwuka, ubushyuhe bwo hejuru 75℃ bushyuha 35℃; Sisitemu yo gukwirakwiza amavuta karemano, ubushyuhe burenze urugero, transformer ikonjeshwa n'umwuka, ubushyuhe bwo hejuru muri rusange ntibukwiriye kurenga 85°C, ubushyuhe bwo hejuru ntibushobora kurenza 95°C ntibushobora kurenza 55°C, niba bigaragaye ko agaciro ntarengwa karenze ibisabwa, bigomba guhita bitanga raporo ku gihe cyo gukora, ikoreshwa ry'ingamba zo kurwanya umutwaro.

1. Ibisobanuro n'imikorere y'ingenzi

Ingufu zikoreshwa mu gusimbuza amavuta zigizwe n'umuringa cyangwa aluminiyumu zizungurutse ku gice cy'icyuma cya silikoni cyashyizwemo laminated. Izi ngufu zishyirwa mu mazutu yuzuye, zikoreshwa mu buryo bubiri: gusimbuza amashanyarazi no gucunga ubushyuhe. Ingufu zihindura amashanyarazi menshi mu gusimbuza amashanyarazi make (cyangwa se mu buryo bunyuranye) binyuze mu gusimbuza amashanyarazi, bigatuma ingufu zikwirakwira mu miyoboro y'amashanyarazi zitekanye.

2. Imiterere y'ibikoresho

Ibikoresho biyobora:

Umuringa: Ikoreshwa cyane cyane mu mizunguruko ifite ingufu nyinshi bitewe n'ubushobozi bwayo bwo gutwara ibintu n'imbaraga za mekanike. Imizunguruko ifite ingufu nke (≤500 kVA) ikunze kugira imiterere y'umuzenguruko ifite urwego rubiri, mu gihe ubushobozi bunini (≥630 kVA) bukoresha imiterere ya helikopu ebyiri cyangwa helikopu enye (≥4) kugira ngo yoroshye ikwirakwizwa ry'amashanyarazi.

Aluminium: Rimwe na rimwe ikoreshwa mu gukoresha ibintu bihendutse, nubwo idakora neza nk'umuringa.
Ubwishingizi bw'umuriro:

Ibikoresho birwanya cyane (urugero: epoxy resins, impapuro zishingiye kuri cellulose) bitandukanya imizunguruko iva mu gice cy'imbere cy'urukuta n'indi.

Ubwishingizi bw'ibikoresho byinshi burinda imiyoboro migufi y'amashanyarazi bitewe n'ubushyuhe cyangwa impinduka mu mikorere y'ikoranabuhanga.

3. Igishushanyo mbonera cy'imiterere

Imiterere yo gufunga:

Guzunguruka kw'ingufu (Cylindrical): Bikunze kugaragara muri transformateur z'ibice bitatu, aho imizunguruko y'ingufu nke ishyirwa mu mizunguruko y'ingufu nyinshi kugira ngo bigabanye ukuva kw'amazi.

Gufunganya hagati y’ibikomere n’ibikomere (Helical): Bikoreshwa mu gukoresha ingufu nyinshi, birimo ibice bifatanye kugira ngo bigabanye igihombo cy’amashanyarazi.

Guhuza Gukonjesha:

Imiyoboro ikoresha imiyoboro y'amavuta kugira ngo ubushyuhe busenyuke binyuze mu buryo busanzwe cyangwa bukoreshejwe imbaraga.

Ibigega bya peteroli bya corrugated bisimbura ibikoresho bisanzwe bibungabunga peteroli, bigatuma ubushyuhe bukwirakwira mu gihe bibungabunga ibidukikije bifunze.

4. Kunoza Imikorere​

Igishushanyo mbonera cy'igihombo gito:

Insinga z'Aloyi Zitagira Ubwiza: Zigabanya hysteresis n'igihombo cy'umuyoboro w'amashanyarazi (urugero, transformers za S11-M zigira igihombo kiri hasi ya 30% ugereranyije n'iza kera)

Itsinda rya Dyn11 Connection: Rigabanya guhindagurika kwa harmonic no kunoza ubwiza bw'ingufu binyuze mu kugabanya imiyoboro ya third-harmonic

Ubudahangarwa bw'uruziga rugufi:

Imigozi yo kuzunguruka ikomeje n'uburyo bwo kuzunguruka butuma imikorere y'imashini iguma neza mu gihe cy'ikosa.

Utwuma twa silica gel na Buchholz relay bigenzura ubushuhe n'ibinyuranyo by'amavuta

5. ​Gusaba no kubungabunga​

Ingero z'ishyirwa mu bikorwa ry'akazi:

Inganda zitanga ingufu, imiyoboro y'amashanyarazi mu mijyi, hamwe n'ingufu zishobora kuvugururwa (urugero, umuyaga ukoreshwa mu mirima).

Ubushobozi bw'amashanyarazi buri hagati ya 50 kVA na 25.000 kVA, hamwe n'amashanyarazi agera kuri 35 kV

Uburyo bwo kubungabunga:

Gufata amavuta buri gihe no gusesengura imyuka ishongeshejwe (DGA) kugira ngo harebwe kwangirika kw'ubushyuhe.

Ishusho y'ubushyuhe kugira ngo hamenyekane ahantu hashyushye cyane mu mizunguruko.

6. Udushya mu Ikoranabuhanga ryo Guhindura Imiterere

Gutera umwuka mu buryo bw'umwuka: Bikuraho imifuka y'umwuka mu gihe cyo gukora, bikongera ubuziranenge bw'ubushyuhe

Igenzura ry’ubwenge: Ibikoresho by’ikoranabuhanga bikoresha IoT bikurikirana ubushyuhe n’imizigo mu gihe nyacyo.
