Roj-immersed transformers yog cov cuab yeej tseem ceeb hauv lub tshuab hluav taws xob, ua kom muaj hluav taws xob hloov pauv thiab hloov hluav taws xob. Lawv txoj haujlwm ua haujlwm yog ua raws li electromagnetic induction, siv cov roj insulating rau rwb thaiv tsev thiab cua sov dissipation, kom ruaj khov thiab ua haujlwm zoo.
1. Electromagnetic Induction raws li lub hauv paus, siab -Efficiency zog hloov
Roj-immersed transformers cia siab rau electromagnetic induction rau lub zog hloov. Lub hauv paus thiab theem nrab windings raug mob rau ntawm ib qho hlau kaw. Thaum AC lub zog hluav taws xob tau siv rau sab xub ntiag, qhov sib nqus sib nqus sib nqus tau tsim tawm, ua rau lub zog hluav taws xob nyob rau sab thib ob, yog li ua tiav qhov hloov pauv hluav taws xob. Qhov voltage piv yog nruj me ntsis sib npaug rau qhov sib piv, piv txwv li, E₁/E₂=N₁/N₂. Qhov no yog lub hauv paus ntsiab lus tseem ceeb tom qab qhov tseeb voltage transformation tiav los ntawm roj-immersed transformers. Cov tub ntxhais hlau yog ua los ntawm txias-cov ntaub ntawv silicon steel, txo qis hysteresis thiab eddy tam sim no poob, thiab txhim kho lub zog efficiency.
2. Dual Functions ntawm rwb thaiv tsev thiab cua txias, roj ncig ua kom muaj kev nyab xeeb
Insulating roj hauv cov roj-immersed transformers ua ob txoj haujlwm ntawm rwb thaiv tsev thiab cua txias. Raws li ib qho nruab nrab insulating, nws zoo cais cov windings, core, thiab grounding Cheebtsam, tiv thaiv sab hauv luv circuits. Raws li qhov nruab nrab cua txias, nws hloov cov cua sov tsim tawm thaum lub sijhawm ua haujlwm rau lub tank phab ntsa los ntawm kev sib txuas, thiab tom qab ntawd dissipates nws los ntawm radiators lossis cua txias kiv cua, tswj kev ua haujlwm ruaj khov ntawm cov cuab yeej ntawm qhov kub thiab txias.
3. Kev sib koom ua ke ntawm cov khoom siv rau kev ruaj ntseg tiv thaiv kev ua haujlwm
Cov roj-immersed transformer yog tsim los ntawm lub cev hloov pauv, lub tank, lub tshuab ua kom txias, thiab cov cuab yeej tiv thaiv ua haujlwm ua ke. Lub cev transformer muaj xws li cov tub ntxhais thiab windings, uas feem ntau teem concentrically los yog overlapping rau optimize electromagnetic kev ua tau zoo. Lub tank kaw tsim kom haum rau lub cev transformer thiab insulating roj; transformers loj kuj tau nruab nrog cov cuab yeej txias kom txhim khu kev tswj thermal. Kev tiv thaiv cov khoom siv xws li cov roj relays saib xyuas cov pa phem thiab ua rau lub tswb nrov, thaum lub tshuab hluav taws xob tswj cov roj hloov pauv thiab tiv thaiv oxidation, ua ke kom ntseeg tau lub sijhawm ntev - lub sij hawm txhim khu kev lag luam ntawm cov roj -immersed transformer.
