Coj mus rhaub Changer Hauv Distribution Transformer
Lub tshuab hluav taws xob faib hluav taws xob yog ib qho tseem ceeb ntawm cov hluav taws xob faib hluav taws xob. Nws yog lub luag haujlwm rau kev xa cov hluav taws xob hluav taws xob uas tsim los ntawm lub tshuab hluav taws xob mus rau lub zog hluav taws xob hauv zos. Fais fab transformers raug ntsia ze ntawm cov neeg siv khoom lossis cov neeg siv hluav taws xob hluav taws xob, thiab lawv lub luag haujlwm tseem ceeb yog hloov cov hluav taws xob siab uas muab los ntawm daim phiaj hluav taws xob mus rau qhov qis dua qhov tsim nyog rau kev siv hauv tsev thiab kev lag luam. Ib qho tseem ceeb ntawm kev faib khoom transformer uas ua rau nws ua haujlwm zoo yog tus kais hloov pauv.
Lub kais hloov pauv yog ib qho cuab yeej uas txuas rau lub tshuab hloov pauv hloov pauv hloov pauv thiab yog lub luag haujlwm los kho qhov hloov pauv cov zis hluav taws xob. Nws yog siv los tswj qhov voltage ntawm tus neeg siv khoom kawg. Kais changers tuaj nyob rau hauv txawv designs thiab configurations, tab sis feem ntau siv ib tug yog on-load tap changer (OLTC).
Lub OLTC muaj qhov zoo ntawm kev muab kev hloov kho lub sijhawm tiag tiag rau lub tshuab hluav taws xob qhov hluav taws xob tsis muaj kev cuam tshuam lub transformer ntawm lub network. Lub OLTC muaj lub cev muaj zog-tsav mechanism uas kho tus naj npawb ntawm lem ntawm lub transformer thib ob winding, hloov cov zis voltage. OLTC feem ntau siv rau hauv kev faib cov khoom siv hluav taws xob vim tias nws muaj txiaj ntsig zoo thiab raug nqi tsawg dua lwm hom kev hloov pauv hloov pauv.
Lwm yam tseem ceeb ntawm tus kais hloov pauv yog qhov off-load kais hloov pauv (OLTC). Tsis zoo li OLTC, tus kais hloov pauv no yuav tsum tau hloov pauv los ntawm lub network ua ntej kev hloov kho tuaj yeem ua. OLTC feem ntau yog siv rau hauv cov khoom siv hluav taws xob nrog cov kev ntsuas hluav taws xob me me vim tias lawv cov qib qis dua.
Hauv cov ntsiab lus, kais hloov pauv ua kom cov khoom xa tawm kom muaj kev nyab xeeb thiab muaj txiaj ntsig zoo rau cov neeg siv khoom. OLTC yog hom kev siv ntau tshaj plaws ntawm cov kais hloov pauv hauv kev hloov pauv hloov pauv thiab muab kev hloov pauv hloov hluav taws xob hauv lub sijhawm. Lub off-load kais hloov pauv, ntawm qhov tod tes, tsis tshua muaj txiaj ntsig, tsis tshua muaj nqi, thiab siv rau hauv cov hloov pauv me me. Raws li kev txhim kho thev naus laus zis, nws muaj kev nyab xeeb los cia siab tias yuav txhim kho cov kev hloov pauv tau zoo dua thiab muaj txiaj ntsig zoo dua los txhim kho qhov kev ua tau zoo ntawm cov khoom siv hluav taws xob sib txuas ntxiv.
