Dab tsi Transformer hloov kho cov lus txhais piv txwv?

Zaj piav

TusTransformer tig sib piv (TTR) xeemYog cov kev kuaj mob thiab kev txais kev soj ntsuam hauv kev hloov pauv tau tseeb tias qhov sib piv ntawm cov xim cua daj cua dub hloov mus rau theem ob yog qhov tseeb thiab phim cov npe tshwj xeeb.

Hauv cov ntsiab lus yooj yim, nws tshaj tawm tias cov kev hloov pauv yuav nqis los yog nqis ntaiv ntawm qhov ntsuas hluav taws xob los ntawm cov nyiaj tau cia siab. Ib qho kev hloov kho kom raug yog qhov tseem ceeb rau kev ua haujlwm tau zoo, kev ua haujlwm, thiab kev ua haujlwm sib txawv ntawm cov hloov pauv hauv lub zog hluav taws xob.

Lub hom phiaj ntawm kev ntsuas

TTR qhov kev xeem yog ua rau:

Txheeb xyuas cov npe ntaus nqi:Xyuas kom meej cov tsim los yog kho hloov pauv hloov tau muaj qhov tseeb tau tsim qauv thiab tau hais rau nws lub npe.

Ntsuam Xyuas Kev Nyab Xeeb WINDING:Tshawb nrhiav luv luv tig nyob rau hauv winding (uas yuav hloov pauv qhov sib piv) thiab qhib kev ncig.

Txheeb cov kais hloov pauv kev ua haujlwm:Txheeb xyuas qhov tseeb ntawm txhua tus kais txoj hauj lwm ntawm tus hloov pauv tus kais hloov pauv. Kev ua haujlwm tsis raug ntawm tus kais hloov pauv tuaj yeem ua rau cov kev cai voltage tsis sib xws.

Ua kom muaj kev ua haujlwm mus rau siab kawg li:Rau cov hloov pauv kom txuas nrog hauv parallel, lawv cov kev sib piv (thiab lwm yam tsis muaj) yuav tsum tau txais kev tiv thaiv kom tsis txhob muaj kev ncig xyuas.

Kev Tu Siab thiab Kev Txij Nkawm:Nws yog tus qauv kuaj thaum lub sijhawm kev teeb tsa, tom qab txij nkawm, lossis thaum muaj kev daws teeb meem.

 

Qhov pib txoj kev xav

Qhov kev xeem yog ua raws cov ntsiab cai tseem ceeb ntawm kev ua haujlwm hloov pauv:

Cov hluav taws xob hloov pauv yog sib npaug nrog cov kab sib piv.

Qhov no yog qhia los ntawm cov qauv:
Vₚ / Vₛ = Nₚ / Nₛ = a
Qhov twg:

V n=voltage

V n=Cov voltage thib ob

Nₚ {= Tus naj npawb ntawm lem ntawm thawj winding

Nₛ {= Tus naj npawb ntawm lem ntawm theem ob winding

=} packs recio

Piv txwv li, transformer nrog tus piv ntawm 10: 1 yuav tsum muaj raws nraim 10 npaug ntawm kev voltage ntau dua nyob rau theem siab thib ob thaum energized.

 

Yuav ua li cas cov kev xeem ua

Qhov kev xeem cuam tshuam nrog ib qho kev paub tsawg - voltage ac teeb liab rau ib qho kev kub hnyiab thiab ntsuas qhov ua rau voltage ntawm lwm cov cua (s). Nws tau uade -} energized(nrog transformer sib txuas ntawm lub zog hluav taws xob).

Muaj ob txoj hauv kev:

1. Voltage txujci (cov qauv classic):

Qhov qes - voltage (feem ntau 120v lossis 240V AC)- voltage (hV) winding.

Cov voltages ntawm HV thiab tsawg {- voltage (LV) windings yog ntsuas ib txhij siv ob voltmeters.

Qhov ntsuas ntsuas (V_HV / V_lV) yog xam thiab piv rau lub npe piv.

Txwv Txwv:Qhov tseeb ntawm txoj kev no yog nyob ntawm qhov tseeb ntawm ob voltmeters.

2. Siv cov qauv ttr tshwj xeeb teeb tsa (niaj hnub hom):

Qhov no yog qhov muaj feem ntau thiab muaj tseeb siv hauv kev ua teb. Ib qho kev ntsuas ttr txiav ttr (piv txwv li, los ntawm megger, omicron, lossis hvvi) yog siv.

Qhov ntsuas muaj cov voltage qhov sib txawv thiab qhov precision Choj Circuit Court uas sib piv cov hloov pauv ntawm tus paub sab hauv kev sib piv.

Tus neeg teb xov tooj txuas rau cov ua rau cov windations transformer, xaiv cov kev cia siab piv txwv, thiab cov twj paj nruag siv voltage thiab muab kev nyeem ncaj qha ntawm covFeem pua ​​yuam kev (%)lossis ntsuas ntsuas ntsuas tiag tiag.

Lub meter mos meter (galvanometer) ntawm cov cuab yeej raug kho kom txog thaum nws nyeem xoom. Kev nyeem ntawv ntawm lub xov tooj ntawm qhov poull no taw qhia qhov sib piv.

Cov txheej txheem rau Kais Hloov:

Qhov kev xeem yog rov ua dua rau txhua tus kais.

Raws li tus kais hloov pauv, qhov sib piv yuav tsum hloov kho kom haum, cov kauj ruam uas tau ua tiav. Ib qho kev sib txawv ntawm cov kais tshwj xeeb qhia teeb meem nrog cov kais sib txuas ntawd tshwj xeeb.

 

Txhais cov txiaj ntsig

Qhov tshwm sim zoo:Qhov ntsuas ntsuas sib piv ntawm cov qauv piv rau hauv kev ua siab ntev heev (feem ntau<±0.5%). For a TTR test set, the percent error is very close to 0%.

Qhov tshwm sim tsis zoo:

Luv lem:Ib puag ncig ib ncig ntawm lem tau zoo txo ​​tus naj npawb ntawm lem hauv qhov cua ntawd. Qhov no ua rau cov ntsuas ntsuas sib piv rau qhov ua kom muaj nuj nqis.

Ntawm hv winding: tus piv yuav yogqi duatshaj qhov xav tau.

Ntawm LV winding: tus piv txwv yuav yogsiab duatshaj qhov xav tau.

Qhib windings:Kev qhib Circuit Court yuav ua rau tsis muaj voltage terred nyob rau lwm winding.

Faulu Kov Changer:Ib txoj hauj lwm tshwj xeeb qhia qhov sib piv tsis raug qhia txog qias neeg, hnav, lossis kev ua tsis raug cai ntawm cov kais.
