Muaj nuj nqi ntawm Distribution Transformer
Kev faib tawm transformer yog ib qho khoom siv hluav taws xob uas tau siv dav hauv kev xa hluav taws xob thiab kev faib hluav taws xob. Nws yog tsim los hloov cov hluav taws xob hluav taws xob siab hluav taws xob los ntawm kev sib kis mus rau lub zog hluav taws xob tsawg, uas yog tsim rau siv hauv tsev, chaw ua haujlwm, thiab lwm lub tsev lag luam. Lub transformer yog ib qho tseem ceeb ntawm daim phiaj hluav taws xob, thiab nws cov kev ua haujlwm tau zoo yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm lub zog hluav taws xob. Hauv tsab xov xwm no, peb yuav muab cov ncauj lus ntxaws ntxaws ntawm daim duab ntawm lub tshuab hluav taws xob faib khoom.
Kev faib tawm transformer muaj ntau yam, nrog rau cov tub ntxhais, winding, thiab rwb thaiv tsev. Cov tub ntxhais yog ua los ntawm cov ntawv laminated steel uas tau teem rau hauv ib yam uas tsim kom muaj kev sib nqus sib nqus. Lub winding yog ua los ntawm tooj liab hlau uas raug mob nyob ib ncig ntawm lub hauv paus. Lub rwb thaiv tsev yog siv los tiv thaiv cov hlau tooj liab los ntawm kev sib cuag nrog lwm qhov ntawm lub transformer, thiab tiv thaiv nws los ntawm noo noo thiab hmoov av.
Daim duab ntawm lub transformer faib qhia tias nws muaj ob qhov tseem ceeb: thawj winding thiab theem nrab winding. Thawj winding yog txuas nrog lub siab voltage fais fab mov, thaum lub thib ob winding yog txuas nrog rau qhov tsawg voltage load. Qhov sib piv ntawm qhov voltage ntawm lub hauv paus thiab theem nrab winding yog txiav txim los ntawm tus naj npawb ntawm lem nyob rau hauv txhua winding.
Lub transformer kuj muaj ob peb lwm yam, xws li bushings, kais changer, thiab cua txias system. Cov bushings yog siv los txuas lub transformer mus rau lub hwj chim kis tau tus mob thiab tis system. Tus kais hloov pauv yog siv los hloov qhov voltage piv ntawm lub transformer, nyob ntawm seb qhov kev thov load. Lub tshuab cua txias yog siv los dissipate lub tshav kub uas tsim los ntawm lub transformer thaum lub sij hawm ua hauj lwm.
Daim duab ntawm lub transformer faib kuj qhia txog ntau hom kev poob uas tshwm sim thaum lub sij hawm hloov hluav taws xob hluav taws xob. Cov kev poob muaj xws li tooj liab poob, hlau poob, thiab stray losses. tooj liab poob tshwm sim vim qhov tsis kam ntawm tooj liab hlau nyob rau hauv winding. Hlau poob tshwm sim vim hysteresis thiab eddy tam sim no poob hauv cov tub ntxhais. Stray losses tshwm sim vim qhov to ntawm cov hlau nplaum flux sab nraum lub hauv paus.
Hauv kev xaus, qhov kev faib tawm transformer yog ib qho tseem ceeb ntawm lub zog xa hluav taws xob thiab kev faib khoom. Nws kev ua haujlwm tau zoo yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm daim phiaj hluav taws xob. Daim duab ntawm lub transformer faib muab cov ncauj lus kom ntxaws txog nws ntau yam khoom thiab lawv txoj haujlwm. Kev nkag siab txog daim duab ntawm kev faib khoom transformer yog qhov tseem ceeb rau txhua tus neeg ua haujlwm hauv kev lag luam hluav taws xob, los ntawm cov kws tsim hluav taws xob mus rau cov neeg ua haujlwm.
