I. Kev qhia lus
Raws li cov cuab yeej tseem ceeb hauv lub zog hluav taws xob, lub tshuab hloov hluav taws xob tseem ceeb ntawm cov hluav taws xob hloov siab tshiab, kev sib kis lub zog, thiab xa tawm. Lawv txoj kev ua haujlwm thev naus laus zis thiab kev nyab xeeb ua haujlwm ncaj qha cuam tshuam rau cov kev sib haum xeeb ruaj khov. Cov kab lus no systematically dissections cov thev naus laus zis ntawm lub zog hloov pauv ntawm peb qhov kev ua haujlwm, kev ua haujlwm ua kom muaj kev txhawb nqa kev ua haujlwm rau kev ua haujlwm.
Ii. Txheej Txheem Txheej Txheem: Lub cev Foundation ntawm Electromagnetic Coupling
1. Cov qauv sib xyaw tiv thaiv
Cov tub ntxhais ntawm lub zog hloov hluav taws xob muaj cov "tseem ceeb-winding-accessory" trinity:
Lub hlwb: Tsim nrog high-permeability txias-rolled silicon steels (ntawm cov qauv sib nqus) txo cov hysteresis thiab eddy kev poob tam sim no (IRON poob). Cov ntsiab lus tseem ceeb txhawb nqa windings windings, thaum tus neeg uas raug kaw lub zog sib nqus rau kev sib nqus sib nqus.
Windings: Tso cai rau cov sulpric (cylindrical / kauv / txuas ntxiv) thiab cuam tshuam (DISC) hom. Kev txhaj tshuaj Windings zoo nkauj (LV) sab hauv thiab hv) sab nraud (HV) sab nraud (nrog cov roj interlayer rau tshav kub dissipation thiab rwb thaiv tsev. Interleaved windings Lwm txoj kev Alm thiab HV discs los ua kom zoo dua cov tshuab muaj zog thiab rwb thaiv tsev. Cov ntaub ntawv (Tooj / Aluminium ua tiav Voltage hloov pauv ntawm tig cov piv (U1 / U2 {4).
Cov Tshuab Accessory:
TANK & CUA TXIAS: Cov hloov roj-roj siv siv cov roj tso tsheb hlau luam nrog cov roj av (txias + rwb thaiv tsev), khub nrog cov twj / kiv cua rau kev ua kom sov dissipation.
Kev Tiv Thaiv Li: Cov nplais vents tso tawm sab hauv siab; Buchholz Reling saib xyuas cov roj (cov pa roj tsawg, cov nkev nce siab).
Kev Tswj Cov Hluav Taws Xob & Rwb Thaiv Tsev: Ntaus cov hloov pauv (on-load / Off-Circuit Court) hloov kho cov qauv sib piv; Insulating bushings refulate thiab txhim kho kev ua.
2. Kev ua haujlwm ua haujlwm: Zog hloov ntawm electromagnetic induction
Raws li F Faraday Txoj Cai, Windings Tsim Kev Xaiv Kev Hloov Kho Flux (lub zog flux) los ntawm lwm cov zog hauv lub zog hauv thawj lub zog hauv thawj lub zog. Qhov tsim nyog, cov tswv yim tawm zog sib npaug hluav taws xob muaj zog (S1=s2), nrog kev sib tw tam sim no kom tig (I1 / i2 {5 / n1). Kev ua tau los muaj xws li:
Hlau poob (poob qis): Hysteresis / Eddy tam sim no poob hauv cov tub ntxhais, nyob ntawm flux ntom thiab ntau zaus.
Tooj liab poob (variable poob): Tsis poob phaus nyob rau hauv windings, proportional rau cov square ntawm load tam sim no.
Zoo tshaj plaws transformer qauv (tsis quav ntsej poob) pab theoretical tsom xam; Cov tswv yim tsim qauv zoo (piv txwv li, amorphous alloy cores txo cov neeg coj mus ua kom zoo rau tooj liab).
III. Kev Ua Haujlwm & Kev Txij Nkawm Feem Ntau: Kev Ntseeg Tau Thoob Ntiaj Teb
1. Kev tswj hwm kev ua haujlwm: Lub xeev-lub xeev thiab kev sib npaug sib npaug
Thauj khoom: Avoid prolonged overload (>15% ntawm kev muaj peev xwm sib tw) los tiv thaiv cov nyiaj liab ploj thiab cua sov. Peb-theem load tsis zoo yuav tsum yog<15% to avoid neutral point 偏移.
Voltage & Kev Ntsuam Xyuas Kub: Kev hloov pauv hloov pauv tsis pub dhau ± 5% ntawm cov nqi ntsuas. Cov roj sab saum toj kub tsawg dua los yog sib npaug rau 95 degree (kub nce dua los yog sib npaug rau 55k), cua sov tsawg dua lossis sib npaug rau 105 degree. Tso cov pa ntsuas hluav taws xob thiab cov sensors ntse rau lub sijhawm tiag tiag saib xyuas.
Rwb Thaiv Tsev Txij Nkawm: Nquag sim roj chromatography (yaj roj kev txheeb xyuas roj), winding DC kuj, thiab dienectric poob yam. Tshawb nrhiav cov rwb thaiv tsev kev laus lossis kev tawm ib nrab (UHF nrhiav kev tshuaj xyuas thev naus laus zis).
2. Cov tswv yim los ua: Tiv Thaiv Cov tswv yim
Neeg Kho Tshuab & Hluav Taws Xob Tshuaj Ntsuam Xyuas: Nrawm winding / tub ntxhais bolts; Tshawb xyuas cov kev sib tsoo / cov kab nrib pleb; ntshiab thaiv cov thawv txias.
Cua Txias Txheej Txheem Tu: Cov roj hloov roj ib txwm hloov rau cov roj-raus cov hluav taws xob (hluavtaws cov roj ester txhim kho ib puag ncig ib puag ncig); Txheeb xyuas cov twj / kiv cua cuam tshuam kev cav. Rau cov tshuab hluav taws xob qhuav, txhim kho qhov cua thiab tiv thaiv kom cov hmoov ntxiv.
Xob Laim & Kev Tiv Thaiv Luv-Circuit Court: Installen Surge ntes (piv txwv li, ZNO ntes); Txhim kho cov hauv paus hauv av (hauv av tsis kam dua lossis muaj sib npaug rau 4ω). Siv cov tshuaj tiv thaiv winding (cov zaus ua haujlwm nrawm nrawm) thiab xa kev phom sij luv luv.
3. Ntse txij nkawm: Digital Hloov Kho Txoj Kev
Ntau qhov chaw soj ntsuam: Sib koom nrog cov roj sib txawv (h₂, chi), chi), thiab ntsuas kub, thiab kev co teeb tsa kom tsim kev kho mob (nyob zoo) qauv.
Txhaum kev kuaj mob & twv ua ntej: Txheeb xyuas cov ntaub ntawv keeb kwm ntawm kev kawm siv tshuab (piv txwv li, SVM) los txheeb xyuas cov npe ntxov (piv txwv li cov kab mob sib tiv thaiv, coj mus sib tw pauv teeb meem).
Nquag tswj thev naus laus zis: Kev txawj ntse kho cov tshuab cua txias thiab cov khoom siv kom hloov pauv hloov. Txhim kho cov txheej txheem kev ua haujlwm ntawm daim phiaj thauj khoom ua kom txo qis (piv txwv li, amorphous alloy cores txiav tsis-thauj khoom poob ntawm 70%).
IV. Kev Tshawb Fawb Kev Tshawb Fawb: Cov ntaub ntawv tshiab thiab cov khoom ntsuab ntsuab
ECO-cov ntaub ntawv thov: Synthetic ester insulating oil (high flash point >300 Degree, biodegradable) hloov cov ntxhia roj rau hauv nroog faib khoom thiab chaw ua haujlwm ib puag ncig.
Cog Lus Tsim: Stereo mob cores (piv txwv li, cov qauv sib xyaw) txo cov khoom siv cov khoom siv, txhim kho qhov chaw siv, thiab qis dua lossis sib npaug ntawm 65db).
Kev koom ua ke ntse: Coothfate Iot thiab ntug sib sau ua ke, kev kuaj tus kheej, thiab kev hloov kho tus kheej, txhawb kev sib txuas ntse ntse.
