Yuav sim kuaj seb puas muaj kev hloov pauv tam sim no ua haujlwm tau zoo?

I. Kev Soj Ntsuam Yooj Yim
1. Pom Kev Kuaj Xyuas
Txheeb xyuas lub pov thawj rau cov kab nrib pleb, hlawv cov cim, lossis xeb, thiab kuaj xyuas cov chaw lim dej xoob.
Paub meej tias tus thawj thiab ob lub clars thib ob yog sau kom meej thiab tias tsis muaj rwb thaiv tsev kev puas tsuaj.
2. Rwb thaiv tsev tsis kam
Siv 2500v Meohmeter ntsuas cov rwb thaiv tsev rwb thaiv tsev tsis kam ntawm thawj winding mus rau theem siab uas muaj winding thiab lub casing. Tus nqi ib txwm yuav tsum muaj ntau dua los yog sib npaug rau 1000mω.
Rau qis - voltage transformers (piv txwv li, 0.66kv), 1000v Meohmermeter tuaj yeem siv, xav tau kev tiv thaiv ntau dua lossis sib npaug nrog 100mω.
Ii. Ua haujlwm ntsuas
1. Kev hloov pauv piv txwv tseeb
Clamp Meter: clamp Lub Koom Haum Thawj Coj ncaj qha rau kev ntsuas tam sim no I1 thiab tus thawj coj theem nrab los ntsuas tam sim no I2. Xam cov kev hloov pauv (I1 / I2) thiab muab piv rau nominal tus nqi. Qhov yuam kev yuav tsum tsawg dua lossis sib npaug rau 5% (rau theem kev tiv thaiv) lossis tsawg dua lossis sib npaug ntawm 2% (rau kev ntsuas qib). Cov txheej txheem tam sim no: thov cov paub tam sim no (piv txwv li, 10A) rau thawj sab thiab ntsuas cov khoom tawm tam sim no ntawm sab nraud nrog kev txheeb xyuas qhov tseeb ntawm cov raug.

2. Polarity Test: Siv DC txujci lossis cov tig rov los xyuas cov tub rog ntawm cov terminals los tiv thaiv kev ntsuas tsis raug lossis tsis muaj kev tiv thaiv.

Kev txheeb xyuas yooj yim: Txuas lub teeb ci rau sab nraud. Yog tias lub teeb taws teeb thaum lub zog siv rau thawj sab, cov polarity yog qhov tseeb.

III. Cov kev ntsuas siab heev

1. Kev Ua Phem Ua Si: Kos tus volt {1} Kuv txoj kev nkhaus

LOTCE TES 10% yuam kev nkhaus kom ntseeg tau qhov tseeb ntawm cov khoom tiv thaiv.

2. Ib nrab Tshem Tawm Tawm Tawm: Transformers ntawm 35kv thiab saum toj no yuav tsum tau siab- zaus ntawm kev tawm tsam ib nrab (tsawg dua lossis sib npaug nrog 50pC).

Txawv txav cua sov lossis suab nrov yuav qhia tau sab hauv.

IV. Txoj kev yooj yim

1. Lub teeb ntsuas lub teeb: Txuas cov teeb ci rau sab nraud. Yog tias lub teeb taws teeb thaum lub zog siv rau thawj sab, cua yog qhov qub (tsuas yog siv rau tsawg {{{{} cov xwm txheej tam sim no). Nco tseg: Hom no tsis tuaj yeem txheeb xyuas qhov kev hloov pauv thiab qhov raug.
2. MOMIMIMALA XAV
Kev tiv thaiv tseem ceeb rau 0-3, tsis kam ua rau kaum tawm rau ntau pua ntawm Ohms; Qhib Circuit Court lossis qhov tsis txaus siab tiv thaiv kev puas tsuaj winding.
Siv cov kev soj ntsuam cov teeb meem los kuaj cov S1-S2 cov chav; Kev txuas ntxiv txuas ntxiv yuav tsum ua tiav.
Cov kev ceev faj
Sab theem nrab sab qhib kev cai lij choj: Qhib kev ci ntsa iab thaum lub sijhawm ua haujlwm yuav tsim muaj kev phom sij siab. Xyuas kom S2 yog tso tawm tau grounded.
Hwj chim - tawm kev ua haujlwm: ua ntej sim lub siab- voltage transform, hwj chim yuav tsum tau disconned thiab tawm.
Tool Xaiv: lub siab - Precision digital multimeter lossis cov ntsuas kev hloov khoom siv clamp yog nyiam. Yuam kev tshaj li 5% yuav tsum tau kho.
