1.1 Tlhaloso ea Morero

1000 kVA three phase pad mounted transformer e ile ea isoa Amerika ka 2024. Matla a lekantsoeng a transformer ke 1000 kVA e nang le pholiso ea ONAN. Matla a phahameng ke 4.16D kV e nang le ± 2 * 2.5% tapping range (NLTC), motlakase o tlaase ke 0.48Y / 0.277 kV, ba thehile sehlopha sa vector sa Dyn1.

Pad-Mounted Transformer ke karolo ea bohlokoa le e ka tšeptjoang ea litsamaiso tsa sejoale-joale tsa ho tsamaisa motlakase, tse etselitsoeng ho theola motlakase o phahameng ho ea ho matla a tlase a hlokoang ke malapa, likhoebo le lits'ebeletso tsa sechaba.

E koaletsoe ka har'a sebaka sa tšepe se notletsoeng,{0}}mohalaleliso oa tšepe, 'me ke lejoe la motheo la marang-rang a motlakase a ka tlas'a lefatše, a loketseng hantle bakeng sa likarohano tsa bolulo, libaka tsa khoebo, le libaka tsa litoropo moo botle le polokeho ea sechaba li leng bohlokoa haholo. Sebopeho sa eona se tlase-se fokotsa ponahalo ea sona ha se ntse se fana ka ts'ebetso e matla.

02 Tlhahiso

2.1 Ntlha ea bohlokoa

Koko ea rona e sebelisa-mekhahlelo e phahameng ea lijo-thollo-mashiti a tšepe a silicon a lebisitsoeng holimo le mohato o nepahetseng-lap lamination. Ha e fokotse-tahlehelo ea mojaro ka 15% ha e bapisoa le kakaretso ea indasteri (e fokotsa litšenyehelo tsa motlakase oa hau) hape e fokotsa lerata/ho thothomela (tlhokomelo e fokolang). Teko e tiileng pele{7}}ea thomello e netefatsa ts'epahalo, e bonts'a R&D ea rona e matla le bokhoni ba ho etsa tlhahiso ho khotsofatsa tlhoko ea hau ea ho sebetsa hantle le boleng.

 

2.2 Ho tsubella

Fumana boleng bo holimo ka li-transformer tsa maqeba tsa aluminium-. Motsoako oa HV foil le LV terata o fana ka ts'epo e netefalitsoeng bakeng sa gridi ea hau, e fokotsa ka kotloloho litšenyehelo tsa bophelo bohle le likotsi tsa ho tima.

 

2.3 Tanka

Tanka e na le moralo o ntlafalitsoeng oa ho pholisa o netefatsang mocheso o tlase oa ts'ebetso. Sena se eketsa ka kotloloho bophelo ba tšebeletso ea transformer le ho ntlafatsa bokhoni ba ho tlala, ho sireletsa matsete a hau ka ts'ebetso e netefalitsoeng,{1}}nako e telele.

 

2.4 Kopano ea ho Qetela

Li-transformer tsa rona li etselitsoe ho kenya kapele le ho bonolo. Likarolo tsohle tsa kahare le kantle li hlahlobiloe-ebile{2}}li kopanngoa esale pele e le karolo e felletseng, e hokahaneng. Sena se u bolokela nako e ngata le litšenyehelo tsa basebetsi nakong ea ho romelloa ha thepa, ha u ntse u etsa bonnete ba hore o sebetsa ka linako tsohle,-ntle le mathata bophelong bohle ba nako e telele ea tšebeletso.

1000kVA ea rona-pase ea mekhahlelo e meraro-e behiloeng ka transformer (4160Δ{7}}480Y/277V, serial 241204) e hlahella ho tsoa ho bahlolisani ba IEEE{12}}e ikamahanyang le (C57.12.00/34/90)2 ea tekolo ea konkreite{17. {27}liphetho tse tsepamisitsoeng tsa bareki. Lintlha tsa bohlokoa: 2.93% max winding resistance resistance (e qoba ho futhumala, ho fokotsa tlhokomelo), -0.13% ho kheloha karo-karolelano ea motlakase (e netefatsa matla a tsitsitseng a theoha), 1.289kW no-load/7.223kW tahlehelo ea mojaro (ka hare ho ± 10% / ± 6% tolerances) 1. (e thibela ho senyeha ha motlakase), 19kV HV/10kV LV mamella liteko (60s, ha ho ho putlama ha motlakase bakeng sa polokeho), tlhahlobo ea mahala ea 20kPa ea lihora tse 12 (e felisa litšenyehelo tsa ho khutlisa oli), le matla a dielectric a oli a 54.9kV (e tiiselletsa ho kenngoa ha nako e telele).

04 Ho paka le ho Romela

4.1 Ho paka

Bakeng sa-mohato oa rona-li-transformer tse kentsoeng, liphutheloana li etelletsa litlhoko tsa hau pele: mekotlana ea foil ea aluminiamo e sa tsoakoang (e nang le li-desiccants ho thibela tšenyo ea mongobo) + likhutlo tse sireletsang + li-crate tsa lehong tse ngotsoeng (forklift/center-ea{5}}matšoao a khoheli). Ha re tlōle mehato, kahoo u fumana russ{{7}e sa senyehang, e sa senyeheng-ea mahala{9}ho sebetsa sebaka sa marang-rang.

 

4.2 Ho tsamaisa thepa

Re fana ka litšebeletso tsa mahala tsa CIF tse se nang mathata, tse sa khathatseheng{0}ho fihla Boema-kepeng ba Los Angeles. Boitseanape ba rona mabapi le thepa ea li-transformer le ts'ireletso e matla ea inshorense e bolela hore re laola likotsi tsohle tsa lipalangoang le litloaelo tsa meetlo. U rua molemo ntlheng e le 'ngoe ea boikarabello, ho netefatsa phano e bonolo, e tšepahalang e sirelletsang kemiso ea nako ea projeke le matsete.

 

 

05 Sebaka le Kakaretso

Marang-rang a hau a kabo e hloka molekane, eseng mofani oa thepa feela. Li-transformer tsa rona tse kentsoeng marang-rang li emela tharollo e felletseng, e tšehelitsoeng ke boiphihlelo ba rona ba tekheniki le boitlamo ba katleho ea hau. Re fana ka melemo e bonahalang eo u e hlokang: moralo o phahameng oa sehlahisoa, thepa e sa sisinyeheng, le tšehetso e sa tsitsang. Re khethele tšebelisano 'moho e ka behang- kotsing letsete la hau le ho fana ka boleng bo sa sekisetseng ho tloha ho litlhaloso ho isa litšebeletsong.
