Ib qho kev faib tawm transformer feem ntau muaj cov hauv qab no qhov tseem ceeb:
- Core
Cov tub ntxhais feem ntau yog ua los ntawm cov ntawv laminated steel los yog cov cores, uas tau muab tso ua ke los tsim ib lub kaw sib nqus sib nqus. Lub hom phiaj tseem ceeb yog los muab txoj hauv kev rau cov hlau nplaum sib nqus uas tsim los ntawm cov transformer thawj thiab theem nrab windings.
- Cua txias
Distribution transformers muaj ob pawg ntawm windings: thawj thiab theem nrab. Thawj winding yog txuas nrog high-voltage hwj chim qhov chaw, thaum lub thib ob winding yog txuas nrog lub low-voltage tis network. Cov windings feem ntau yog ua los ntawm tooj liab lossis aluminium conductors thiab yog insulated los tiv thaiv hluav taws xob luv luv.
- Rwb thaiv tsev
Cov ntaub ntawv rwb thaiv tsev yog siv rau hluav taws xob cais cov windings thiab cov tub ntxhais ntawm ib leeg thiab muab lub zog dielectric. Insulating cov ntaub ntawv xws li ntawv, pressboard, thiab roj impregnated cov ntaub ntawv yog feem ntau siv nyob rau hauv tis transformers.
- Tank
Lub tank yog lub kaw lus kaw uas muaj lub tsev hloov pauv lub hauv paus, windings, thiab cov ntaub ntawv insulating. Nws feem ntau yog ua los ntawm cov hlau thiab muab kev tiv thaiv thiab kev tiv thaiv rau cov khoom siv hluav taws xob. Lub tank ntim nrog cov roj insulating los muab cov cua txias thiab hluav taws xob rwb thaiv tsev.
- Txias System
Distribution transformers xav tau lub tshuab cua txias kom dissipate cua sov tsim thaum lub sijhawm ua haujlwm. Txoj kev ua kom txias tshaj plaws yog roj-immersed thiab cua-txias. Nyob rau hauv cov roj-immersed transformers, cov roj insulating ua raws li ib tug coolant thiab hloov tshav kub los ntawm cov tub ntxhais thiab windings mus rau lub tank nto, qhov twg nws yog dissipated mus rau ib puag ncig ib puag ncig. Cua-txias transformers siv cov kiv cua sab nraud los yog ntuj convection kom txias cov windings ncaj qha.
- Coj mus rhaub Changer
Qee qhov kev faib khoom siv hluav taws xob muaj cov kais hloov pauv, uas yog cov khoom siv uas tso cai rau kev hloov pauv qhov hloov pauv thiab yog li cov zis hluav taws xob ntawm lub tshuab hloov pauv. Kais hloov pauv yog siv los them rau qhov hloov pauv ntawm qhov hluav taws xob hauv lub zog hluav taws xob thiab xyuas kom meej tias qhov xav tau qhov hluav taws xob xa mus rau lub network faib.
- Bushings
Bushings yog cov khoom siv insulating uas muab txoj hauv kev rau kev txuas cov high-voltage thiab low-voltage terminals ntawm transformer mus rau sab nraud fais fab system. Lawv kuj muab hluav taws xob rwb thaiv tsev thiab kev txhawb nqa txhua yam rau cov conductors hla lub tank.
- Khoom siv
Kev faib tawm transformers tuaj yeem suav nrog ntau yam khoom siv xws li ntsuas kub thiab ntsuas ntsuas, ntsuas kev ntsuas siab, ntsuas qib roj, thiab Buchholz relay (cov cuab yeej tiv thaiv uas kuaj pom qhov tsis raug ntawm lub transformer).
Cov no yog cov khoom tseem ceeb ntawm kev faib khoom transformer, txawm hais tias lawv cov kev tsim tshwj xeeb thiab kev teeb tsa yuav txawv nyob ntawm qhov ntsuas qhov ntsuas thiab daim ntawv thov.
