Dab tsi yog qhov ua haujlwm ntawm - Pead LOAD KIS HLOOV?

Cov lus qhia ntxaws ntxaws

Kom nkag siab txog nws txoj haujlwm, peb tawg vim li cas nws xav tau thiab nws ua haujlwm li cas.

1. Qhov teeb meem tseem ceeb: voltage hloov pauv

Hauv hluav taws xob hluav taws xob, lub voltage ntawm ib qho ntsiab lus muab tsis tas li. Nws hloov vim yog:

Varying loads: Thaum lub cev muaj zog loj pib, nws hloov ib qho loj loj tam sim no, ua rau muaj hluav taws xob ib ntus poob ("sag") rau lwm tus neeg yuav khoom ntawm tib txoj kab. Hloov siab, thaum thauj khoom yog tam sim ntawd tshem tawm, voltage tuaj yeem zoo li cas.

Kab poob: Raws li hluav taws xob taug kev ntev ntev los ntawm cov kab hluav taws xob, qhov xam tiv thaiv cov xov hlau ua rau hluav taws xob ua rau muaj hluav taws xob poob. Lub voltage nyob rau thaum xaus ntawm txoj kab pub pub feeder ntev yuav qis dua ntawm kev hloov.

Cov neeg siv khoom thiab cov cuab yeej xav tau ib qho kev ntsuas hluav taws xob ruaj khov los ua haujlwm kom raug thiab muaj txiaj ntsig. Siab dhau los lossis dhau kev voltage qis tuaj yeem ua rau cov khoom siv puas tsuaj lossis txo nws lifespan.

2. Kev daws teeb meem: Hloov kho cov kab sib piv

Ib qho kev hloov pauv ua haujlwm ntawm lub hauv paus ntsiab lus ntawm indcrotion induction, qhov twg lub voltage sib tshooj tau sib npaug ntawm cov tig sib piv ntawm Thawj Qhov Wirming:

V_primary / v_secondary ≈ n_primary / n_thecondary

Ib qho OLTC lub cev hloov pauv no lem (n_primary / n_secondary) los ntawm kev sib txuas rau cov sib txawv "cov ntsiab lus sib txuas" (cov ntsiab lus sib txuas) ntawm transformer winding. Los ntawm kev xaiv cov kais sib txawv, tus naj npawb ntawm cov nquag hloov pauv tau zoo zuj zus lossis txo qis cov zis hluav taws xob.

Txhawm rau tsa cov voltage thib ob hluav taws xob: Tus kais hloov chaw xaiv cov kais uas txo tus naj npawb ntawm lem hauv thawj lub winding (lossis nce lawv hauv theem ob).

Txhawm rau txo cov voltage thib ob: Tus kais hloov chaw xaiv cov kais uas nce tus naj npawb ntawm cov lem ntawm thawj lub winding (lossis txo qis hauv theem ob).

3. Qhov kev sib tw tseem ceeb: ua qhov hloov pauv "ntawm {{1} log"

Qhov kev sib tw ua haujlwm tseem ceeb yog tias koj tsis tuaj yeem qhib Circuit Court mus hloov cov kais dej thaum lub transformer yog muab cov thauj khoom tam sim no. Rhuav cov Circuit Court hauv qab load yuav tsim lub arc muaj zog, rhuav tshem cov kais hloov thiab muaj peev xwm ua rau tawg.

 

AltC daws qhov no:
Ib qho OLTC yog ib qho nyuaj hloov kho nrog lub tshuab hloov kev hloov pauv yooj yim. Feem ntau cov qauv siv tau siv cov pob taws thiab hloov mus.

Nws luv luv txuas ob sab uas nyob ze.

Nws siv cov khoom tsim tawm mus rau ib ntus kev sib tw ntawm cov kais dej.

Tom qab ntawd hloov cov thauj khoom tam sim no los ntawm tus qub kais mus rau tus kais tshiab.

Thaum kawg, nws disconntts tus kais qub.

Tag nrho cov txheej txheem tshwm sim nyob rau hauv ib feem ntawm ib ob, ua kom muaj kev hloov pauv kom muaj kev cuam tshuam lub hwj chim ntws.

 

Cov haujlwm tseem ceeb thiab cov hom phiaj taw tes:

Cov kev tswj hwm kev tswj hwm: Cov haujlwm tseem ceeb. Nws tau tswj hwm cov zis ruaj khov rau kev sib hloov hluav taws xob txawm hais tias hloov pauv hauv thawj voltage lossis lub nra.

Reflective zog tswj: Los tswj qhov voltage, lub oltc indirection pab tswj cov ntws ntawm reactive zog hauv lub network, uas yog qhov tseem ceeb rau cov kab ke ruaj khov.

Lub High zog kev ruaj siab: nws ntseeg tau tias cov neeg siv tau voltage tsis pub dhau ib qho kev zam txim rau hauv ib qho kev tsim nyog los them nyiaj (piv txwv li 10%), tiv thaiv lawv cov cuab yeej cuab tam thiab tshuab.

System Muaj zog: Los ntawm kev tswj voltage profiles hla lub hwj chim collapse, muaj ib tus mob uas tuaj yeem ua rau muaj kev cuam tshuam rau kev kub ntxhov.

 

OLTCS nyob qhov twg OLTCS siv?

OLTCS yuav luag txhua lub sijhawm nyob:

Lub zog hloov hluav taws xob hauv kev sib kis thiab cov khoom xa tawm.

Kev faib tawm loj loj muab cov khoom lag luam muab khoom siv lossis cov chaw loj.
