Ukujikeleza kweTransformer efakwe kwiOyile: Ukuqonda koBugcisa kunye neempawu zoYilo

Isiguquli esintywiliselwa kwioyile Iiwindings zizinto ezibalulekileyo kwiinkqubo zokusasazwa kwamandla, ezenzelwe ukuhambisa amandla ombane ngokufanelekileyo ngelixa ziqinisekisa ukuthembeka nokuqina. Apha ngezantsi kukho uhlalutyo oluneenkcukacha lwesakhiwo sazo, izixhobo, kunye nemigaqo yokusebenza, eyenziwe ngokwemigangatho yoshishino kunye neenkcukacha zobugcisa.

Ubushushu obuphezulu be-transformer entywilisiweyo kwi-oyile abuvumelekanga ukudlula i-95 ° C, ngokubanzi akuvumelekanga ukudlula i-85 ° C, ukhetho oluqhelekileyo lwe-transformer winding material ye-insulation layer yeklasi A, ubushushu obuphezulu obuvumelekileyo bezinto zokufakelwa yi-95 ~ 105 ° C, kwiinkcukacha zokufudumeza ze-transformer zaseTshayina zisekelwe kubushushu obusebenzayo be-40 ° C njengomgangatho, ukujija kobushushu obuphakathi begesi obuqukwe kwi-65 ° C, Ukunyuka kobushushu be-oyile ephezulu ukuya kwigesi kubekwe ngokuchanekileyo kwi-55 ° C, ngoko ukujija okuqulethe isiseko se-transformer kuqukwe ekunyukeni kobushushu be-oyile kwi-10 ° C.

Ukuba ubushushu obuphezulu be-transformer buyi-85 ° C, ubushushu bokujika buyi-95 ° C; Ukuba ubushushu obuphezulu buyi-95 ° C, ubushushu bokujika buyi-105 ° C, obufikelele kubushushu obuphezulu obuvumelekileyo bezinto zokwambathisa ezijijekileyo. Ubushushu obuphezulu kakhulu buya kukhawulezisa ukuguga kwezinto zokwambathisa ezijijekileyo, bukhawulezise ukonakala kweoyile ye-transformer, bonakalise ubomi benkonzo Isiguquli soSasazos, kwaye zide zikhokelele kwiingozi zokhuseleko.

Inkqubo enamandla yokujikeleza ioyile epholileyo emoyeni, ubushushu obuphezulu buyi-75℃ yokufudumala buyi-35℃; Inkqubo yokujikeleza ioyile yendalo, ukhuseleko lobushushu obugqithisileyo, i-transformer epholileyo emoyeni, ubushushu obuphezulu abufanelekanga ngokubanzi ukuba budlule kuma-85°C, ubushushu obuphezulu abuyi kudlula kuma-95°C, ukuba ixabiso elilinganiselweyo lidlula iimfuno, kufuneka libike ngoko nangoko ishedyuli yemveliso, ukusetyenziswa kwemilinganiselo yokumelana nomthwalo.

1. Inkcazo kunye nomsebenzi oyintloko

Iiwindings zetransformer ezintywilisiweyo kwioyile zenziwe ngeekhoyili zobhedu okanye zealuminiyam ezijikelezwe yintsimbi yesilicon elaminethiweyo. Ezi windings zifakwe ngokupheleleyo kwioyile yokukhusela, esebenzela iinjongo ezimbini: ukufakelwa kombane kunye nolawulo lobushushu. Iiwindings ziguqula igalelo le-high-voltage libe yimveliso ye-low-voltage (okanye ngokuchaseneyo) nge-electromagnetic induction, evumela ukudluliselwa kwamandla okukhuselekileyo kwiigridi.

2. Ukwakhiwa kwezinto

Izinto zokuqhuba:

Ubhedu: Isetyenziswa kakhulu kwiiwindings ezine-voltage ephezulu ngenxa yokuqhuba kwayo okuphezulu kunye namandla oomatshini. Iiwindings ezine-voltage ephantsi (≤500 kVA) zihlala zisebenzisa isakhiwo se-cylindrical esineengqimba ezimbini, ngelixa amandla amakhulu (≥630 kVA) asebenzisa ii-double-helix okanye ii-quadruple-helix configurations ukuze kuphuculwe ukusasazwa kwangoku.

I-Aluminiyam: Isetyenziswa ngamanye amaxesha kwiindawo ezixabisa kakhulu, nangona ingasebenzi kakuhle njengethusi.
Ubushushu:

Izixhobo ezixhathisa kakhulu (umz. ii-epoxy resins, iphepha elisekwe kwi-cellulose) zahlula ii-windings ukusuka embindini ukuya kwenye.

Ukufakwa kwe-insulation okune-multilayer kuthintela ii-short circuits phantsi koxinzelelo lobushushu okanye ukuguqulwa koomatshini.

3. Uyilo lweZakhiwo

Ulungiselelo lokujika:

Ukujika okuNgqingqileyo (okuyiCylindrical): Kuqhelekile kwiitransformer zesigaba esithathu, apho ukujika okunevolthi ephantsi kubekwa ngaphakathi kokujika okunevolthi ephezulu ukunciphisa ukuvuza kwamanzi.

Ukujika kweLayer-Wound (Helical): Kusetyenziselwa usetyenziso lwamandla aphezulu, oluneeleya ezidityanisiweyo ukunciphisa ilahleko zamandla e-eddy.

Ukuhlanganiswa kokupholisa:

Iiwindings zifaka imibhobho yeoyile ukuhambisa ubushushu ngendlela yendalo okanye enyanzelisiweyo.

Iitanki zeoyile ezifakwe i-corrugated zithatha indawo yezixhobo zokugcina izinto zemveli, zivumela ukwanda kobushushu beoyile ngelixa zigcina indawo evaliweyo.

4. Ukuphucula Ukusebenza​

Uyilo lwelahleko ephantsi:

Ii-Amorphous Alloy Cores: Zinciphisa i-hysteresis kunye nokulahleka kwe-eddy current (umz., ii-S11-M series transformers zifumana ilahleko eziphantsi ngama-30% kuneemodeli ezindala)

Iqela loQhagamshelo lweDyn11: Linciphisa ukuphambuka kwe-harmonic kwaye liphucula umgangatho wamandla ngokunciphisa imisinga ye-harmonic yesithathu

Ukumelana neSekethe elifutshane:

Iikliphu zokujika eziqinisiweyo kunye neendlela zokujika ezijikelezayo zonyusa uzinzo loomatshini ngexesha leemeko zokungasebenzi kakuhle.

Iibreather zeSilica gel kunye neeBuchholz relays zijonga umswakama kunye nokungahambi kakuhle kokuhamba kweoyile

5. ​Ukufaka isicelo kunye nokugcinwa​

Iimeko zokusasazwa:

Izitishi zemizi-mveliso, iigridi zamandla zasezidolophini, kunye neenkqubo zamandla avuselelekayo (umz., iifama zomoya).

Amandla alinganisiweyo aqala kwi-50 kVA ukuya kwi-25,000 kVA, kunye nee-voltage ezifikelela kwi-35 kV

Iindlela Zokulungisa:

Ukuthatha iisampulu zeoyile rhoqo kunye nohlalutyo lwegesi enyibilikisiweyo (i-DGA) ukuze kubonwe ukonakala kwe-insulation.

Imifanekiso yobushushu ukuze kuchongwe iindawo ezishushu ezikwiindawo ezijikelezileyo.

6. Utshintsho kwiTekhnoloji yokuVula

Ukufunxwa kweVacuum: Kususa iipokotho zomoya ngexesha lokwenziwa, kuphucula ukuthembeka kokufakwa kwe-insulation

Ukubeka esweni okukrelekrele: Izinzwa ezisebenzisa i-IoT zilandelela ubushushu bokujikeleza kunye nobunzima bomthwalo ngexesha langempela.
