Ukubopha i-Transformer Ecwiliswe Kuwoyela: Ukuqonda Kobuchwepheshe kanye nezici Zokuklama

I-Transformer Ecwiliswe Kuwoyela Ama-winding ayizingxenye ezibalulekile ezinhlelweni zokusatshalaliswa kwamandla, aklanyelwe ukudlulisa amandla kagesi ngempumelelo ngenkathi kuqinisekiswa ukuthembeka nokuqina. Ngezansi ukuhlaziywa okuningiliziwe kwesakhiwo sawo, izinto zokwakha, kanye nezimiso zokusebenza, ezenziwe ngezindinganiso zemboni kanye nezincazelo zobuchwepheshe.

Izinga lokushisa eliphezulu le-transformer elicwiliswe uwoyela alivunyelwe ukudlula u-95 ° C, ngokuvamile alivunyelwe ukudlula u-85 ° C, ukukhethwa okujwayelekile kwe-transformer winding yezinto zokufaka ungqimba lwesigaba A, izinga lokushisa eliphakeme elivumelekile lezinto zokufaka ugesi lingu-95 ~ 105 ° C, ngokwezincazelo zokushisa ze-transformer zaseShayina zisekelwe ekushiseni okusebenzayo okungu-40 ° C njengokujwayelekile, ukugoqa kwesilinganiso sokushisa kwegesi esifakiwe ku-65 ° C, Ukwenyuka kwezinga lokushisa likawoyela ophezulu kuya kugesi kubekwe ngokunembile ku-55 ° C, ngakho ukugoqa okuqukethe umongo we-transformer kufakiwe ekukhuphukeni kwezinga lokushisa likawoyela ku-10 ° C.

Uma izinga lokushisa eliphezulu le-transformer lingu-85 ° C, izinga lokushisa lokugoqa lingu-95 ° C; Uma izinga lokushisa eliphezulu lingu-95 ° C, izinga lokushisa lokugoqa selifinyelele ku-105 ° C, elifinyelele izinga lokushisa eliphezulu elivumelekile lezinto zokufaka ungqimba olugoqayo. Izinga lokushisa eliphakeme kakhulu lizosheshisa ukuguga kwezinto zokufaka ungqimba olugoqayo, lisheshise ukuwohloka kukawoyela we-transformer, lilimaze impilo yenkonzo yalo. Isiguquli Sokusabalalisas, futhi kuholele ngisho nasezingozini zokuphepha.

Isistimu eqinile yokujikeleza uwoyela epholile emoyeni, izinga lokushisa eliphezulu 75℃ ukufudumala 35℃; Uhlelo lokujikeleza uwoyela lwemvelo, ukuvikelwa kokushisa okweqile, i-transformer epholile emoyeni, izinga lokushisa eliphezulu ngokuvamile alifaneleki ukudlula 85 ° C, izinga lokushisa eliphezulu alikwazi ukudlula 95 ° C alikwazi ukudlula 55 ° C, uma kutholakala ekusebenzeni kwenani elilinganiselwe lidlula izidingo, kufanele libike ngokushesha ukuhlela ukukhiqizwa, ukusetshenziswa kwezinyathelo zokumelana nomkhawulo womthwalo.

1. Incazelo kanye Nomsebenzi Oyinhloko

Ama-windings e-transformer acwiliswe uwoyela aqukethe ama-coil ethusi noma e-aluminium aboshwe nxazonke kwensimbi ye-silicon elaminethiwe. Lawa ma-windings acwiliswe ngokuphelele ku-oyela ovikelayo, okufeza izinjongo ezimbili: ukuvikela ugesi kanye nokuphathwa kokushisa. Ama-windings aguqula okokufaka kwe-high-voltage kube ukuphuma kwe-low-voltage (noma okuphambene nalokho) ngokungenisa kwe-electromagnetic, okuvumela ukudluliselwa kwamandla okuphephile kuwo wonke ama-grid.

2. Ukwakheka Kwezinto

Izinto Eziqhuba Umoya:

Ithusi: Isetshenziswa kakhulu kuma-windings ane-voltage ephezulu ngenxa yokuqhuba kwayo okuphezulu kanye namandla omshini. Ama-windings ane-voltage ephansi (≤500 kVA) avame ukusebenzisa isakhiwo se-cylindrical esinezingqimba ezimbili, kuyilapho amandla amakhulu (≥630 kVA) esebenzisa ukucushwa kwe-double-helix noma i-quadruple-helix ukuze kuthuthukiswe ukusatshalaliswa kwamanje.

I-Aluminium: Isetshenziswa ngezikhathi ezithile ekusetshenzisweni okungabizi kakhulu, yize ingasebenzi kahle kunethusi.
Ukuvikela:

Izinto ezimelana kakhulu (isb., ama-epoxy resins, iphepha elisekelwe ku-cellulose) zihlukanisa ama-windings kusuka enkabeni kuya komunye nomunye.

Ukufakwa kwe-insulation okunezingqimba eziningi kuvimbela imijikelezo emifushane ngaphansi kokucindezeleka kokushisa noma ukuguqulwa komshini.

3. ​Umklamo Wesakhiwo​

Ukuhlelwa Kokugoba:

Ukugoba Okuyindilinga (Okuyindilinga): Okuvamile kuma-transformer ezigaba ezintathu, lapho ukugoba okune-voltage ephansi kufakwa khona ngaphakathi kokugoba okune-voltage ephezulu ukuze kuncishiswe ukuvuza.

Ukugoba Kwezingqimba Nezinxeba (I-Helical): Kusetshenziselwa izinhlelo zokusebenza zamandla aphezulu, ezinezingqimba ezihlanganisiwe ukunciphisa ukulahlekelwa kwamandla e-eddy.

Ukuhlanganiswa Kokupholisa:

Ama-winding afaka amapayipi kawoyela ukuze ahambise ukushabalaliswa kokushisa nge-convection yemvelo noma ephoqelelwe.

Amathangi kawoyela ane-corrugated athatha indawo yabalondolozi bendabuko, okuvumela ukwanda kokushisa kwamafutha ngenkathi kugcinwa indawo evalekile.

4. ​Ukuthuthukisa Ukusebenza​

Umklamo Wokulahlekelwa Okuphansi:

Ama-Amorphous Alloy Cores: Anciphisa i-hysteresis kanye nokulahlekelwa yi-eddy current (isb., ama-S11-M series transformers athola ukulahlekelwa okuphansi ngo-30% kunamamodeli amadala)

Iqembu Lokuxhumana le-Dyn11: Linciphisa ukuphambuka kwe-harmonic futhi lithuthukisa ikhwalithi yamandla ngokunciphisa amaza e-harmonic e-third-harmonic

Ukumelana Nesiyingi Esifushane:

Ama-clamp okugoqa aqinisiwe kanye namasu okugoqa ajikelezayo athuthukisa ukuzinza komshini ngesikhathi sezimo zamaphutha.

Ama-breather e-silica gel kanye nama-Buchholz relay aqapha ukungalingani komswakama kanye nokugeleza kwamafutha

5. ​Ukufaka Isicelo Nokulungisa​

Izimo Zokusetshenziswa:

Iziteshi ezincane zezimboni, amagridi kagesi asemadolobheni, kanye nezinhlelo zamandla avuselelekayo (isb., amapulazi omoya).

Amandla alinganisiwe asukela ku-50 kVA kuya ku-25,000 kVA, kanye nama-voltage afinyelela ku-35 kV

Imikhuba Yokulungisa:

Ukuthatha amasampula kawoyela njalo kanye nokuhlaziywa kwegesi encibilikisiwe (i-DGA) ukuthola ukonakala kokushisa.

Izithombe ezibonisa ukushisa ukuze kutholakale izindawo ezishisayo ezitholakala ezindaweni ezizungezile.

6. Izinto Ezintsha Kubuchwepheshe Bokujika

Ukufakwa kwe-Vacuum: Kususa ama-air pocket ngesikhathi sokukhiqiza, kuthuthukisa ubuqotho bokufudumeza

Ukuqapha Okuhlakaniphile: Izinzwa ezisebenzisa i-IoT zilandelela izinga lokushisa lokujikeleza kanye nokuguquguquka komthwalo ngesikhathi sangempela.
