Nrov Science|Kev soj ntsuam ntawm Txoj Cai Ua Haujlwm thiab Cov Ntawv Thov Tseem Ceeb ntawm Fais Fab Transformers
Transformers yog cov cuab yeej tseem ceeb hauv kev xa hluav taws xob thiab kev faib hluav taws xob, dav siv hauv nroog thiab thaj chaw hluav taws xob hluav taws xob, chaw ua lag luam thiab thaj chaw, chaw ua si, thiab cov phiaj xwm hluav taws xob xws li photovoltaics, lub zog cia, thiab them pawg. Lawv yog cov chaw tseem ceeb rau kev ua kom muaj zog sib kis tau zoo thiab muaj kev nyab xeeb ntawm kev siv hluav taws xob. Kab lus no muab cov lus piav qhia luv luv ntawm cov ntsiab lus tseem ceeb ua haujlwm thiab kev siv qhov zoo ntawm transformers.
Lub hauv paus ntsiab lus ntawm kev khiav hauj lwm ntawm lub transformer yog electromagnetic induction. Nws feem ntau muaj cov tub ntxhais hlau, lub hauv paus kauj, thiab lub kauj thib ob. Cov khoom siv tsis muaj cov qauv sib kis; nws tso siab rau kev sib pauv ntawm cov hluav taws xob hluav taws xob kom ua tiav qhov hluav taws xob thiab kev tswj hwm tam sim no, muaj cov txiaj ntsig zoo xws li kev ua haujlwm ruaj khov, kev siv hluav taws xob tsawg, thiab hnav tsis zoo.
Nws txoj haujlwm ua haujlwm yooj yim thiab ua haujlwm tau zoo: Tom qab thawj kauj ruam txuas nrog AC voltage, nws tsim ib qho chaw sib nqus sib nqus los ntawm cov tub ntxhais hlau, ua kom tiav cov kev hloov hluav taws xob rau hauv lub zog sib nqus; lub magnetic teb nkag mus rau theem ob kauj kom induce voltage, realizing lub conversion ntawm magnetic zog rau hauv hluav taws xob zog. Cov cuab yeej ua tiav cov kauj ruam voltage-nce thiab qib- nqes kev cai los ntawm kev kho cov lem piv ntawm lub hauv paus thiab theem nrab coils, hloov mus rau qhov sib txawv ntawm cov xwm txheej sib kis.
Tam sim no, hom kev lag luam tseem ceeb hauv kev lag luam yog cov roj- raus thiab qhuav- hom hloov pauv, hloov mus rau qhov sib txawv. Roj-immersed transformers muab cov cua kub zoo tshaj plaws thiab tus nqi- kev ua tau zoo, ua rau lawv tsim nyog rau cov phiaj xwm hluav taws xob sab nraum zoov thiab cov phiaj xwm hluav taws xob hauv nroog thiab hauv nroog; qhuav- hom transformers muaj kev nyab xeeb, nplaim taws-retardant, thiab txij nkawm-dawb, thiab tau dav siv nyob rau hauv kev lag luam thiab chaw nyob, chaw ua si hauv tsev, thiab lwm yam kev siv zoo sib xws.
