Phau Ntawv Qhia Txog Cov Khoom Siv Teeb Meem rau Transformer Periodic Testing Laboratories

Kev ntsuam xyuas ib ntus ntawm transformers yog kauj ruam tseem ceeb los xyuas kom meej cov khoom siv ruaj khov. Hom kev sim no tsom mus rau kev txheeb xyuas qhov ua tau zoo niaj hnub thiab tsis suav nrog cov khoom ntsuas xws li ntsuas kub nce lossis ntsuas kev ntsuas. Raws li kev xav tau, cov khoom siv hauv chav kuaj tuaj yeem teeb tsa nyob ib ncig ntawm ob lub ntsiab lus qhia: kev ntsuas hluav taws xob thiab kev saib xyuas roj, raws li cov lus qhia hauv qab no:

1. Cov khoom siv ntsuas hluav taws xob: Cov cuab yeej ntsuas tseem ceeb

Cov ntsuas hluav taws xob yog cov cim qhia tseem ceeb rau kev ntsuas kev noj qab haus huv ntawm lub tshuab hluav taws xob hauv kev sim ntsuas lub sijhawm. Cov khoom siv hauv qab no yuav tsum tau teeb tsa:

Rwb thaiv tsev Resistance Meter: Ntsuas rwb thaiv tsev tiv thaiv ntawm windings, bushings, thiab lwm yam., txhawm rau txheeb xyuas cov rwb thaiv tsev laus lossis noo noo;

Capacitive Voltage Divider / Fais Fab Zaus Capacitive Voltage Divider: Ua haujlwm nrog qhov hluav taws xob - nrog rau cov khoom siv ntsuas siab - sab voltage;

DC Resistance Tester: Ntsuas DC tsis kam ntawm windings kom paub txog cov teeb meem xws li kev sib cuag tsis zoo lossis kev sib tshuam -tig luv Circuit Court;

Tsis Siv Neeg Variable-Frequency Dielectric Loss Tester: Nthuav dielectric poob yam tseem ceeb ntawm rwb thaiv tsev xov xwm kom muaj kev cuam tshuam cov dej los yog degradation;

Tsis Siv Neeg Turn Ratio Tester: Txheeb xyuas seb puas muaj qhov sib tw winding raws li cov qauv tsim kom tsis txhob muaj qhov sib txawv ntawm qhov sib txawv;

Tam sim no / Voltage Transformer: Koom tes nrog lwm yam khoom siv los ntsuas thiab hloov hluav taws xob ntau;

Test Transformer + Fais Fab Zaus Nrog Voltage Tester: Ua lub zog zaus tiv thaiv qhov ntsuas hluav taws xob ntawm windings thiab bushings los xyuas qhov muaj zog rwb thaiv tsev;

Multi-Channel Partial Discharge Detector: Txheeb xyuas cov teeb liab sab hauv ib nrab los txheeb xyuas qhov cuam tshuam ntawm rwb thaiv tsev thaum ntxov;

Ntawm -Load Tap Changer Yam ntxwv Tester: Kev ntsuas kais hloov pauv tsis tau (piv txwv li, lub sijhawm ua haujlwm, tsis kam) kom ntseeg tau tias muaj kev tswj hwm hluav taws xob;

Lwm Cov Khoom Siv Pabcuam: Xws li lub zog ntsuas ntsuas (kev ntsuas lub zog muaj peev xwm), lub tshuab cua deformation (kuaj xyuas cov tshuab winding deformation), qhov ntsuas hluav taws xob (kho qhov ntsuas hluav taws xob), lub tshuab hluav taws xob muaj peev xwm ntsuas (tshem cov cuab yeej muaj peev xwm), thiab ntsuas lub ntsuas hluav taws xob (ua ke nrog kev ntsuas ntsuas kev ua haujlwm).

2. Cov Khoom Siv Roj Ntsuas: Qhov tseem ceeb rau kev soj ntsuam roj

Transformer roj yog qhov tseem ceeb rau kev rwb thaiv tsev thiab cua txias, thiab nws qhov xwm txheej ncaj qha cuam tshuam rau cov khoom siv kev nyab xeeb. Cov cuab yeej ntsuas roj hauv qab no yuav tsum tau teeb tsa:

Roj Chromatograph Analyzer: Tshawb xyuas cov khoom tawg (piv txwv li, methane, acetylene) hauv cov roj txhawm rau txheeb xyuas hom kev ua txhaum sab hauv (overheating, tso tawm, thiab lwm yam);

Roj Dielectric Strength Tester: Kev ntsuas roj tawg hluav taws xob los ntsuas kev ua haujlwm rwb thaiv tsev;

Roj Dielectric Loss Tester: Tshawb xyuas cov roj dielectric poob ntawm cov roj kom pom kev sib kis lossis kev laus;

Moisture Tester: Ntsuas cov dej hauv cov roj los tiv thaiv kev puas tsuaj los ntawm kev ya raws;

Flash Point Tester: Txiav txim siab roj flash point los ntsuas kev nyab xeeb kev ua haujlwm;

Acid Value Tester: Tshawb xyuas cov roj acid tus nqi los txiav txim oxidative degradation;

Surface Tension Tester: Ntsuam xyuas cov roj saum npoo los pab txiav txim cov roj degradation.

3. Tsis yog- Cov Khoom Siv Tseem Ceeb: Xaiv tau raws li xav tau

"Liab Impulse Test Transformer" yog ib yam khoom siv kuaj. Nws tsis tas yuav tsum yog tias tsuas yog kuaj raws sijhawm.

Nrog rau kev teeb tsa kev tsim nyog ntawm cov khoom siv saum toj no, lub transformer periodic test laboratory tuaj yeem ua tiav cov kev ntsuam xyuas tseem ceeb (kev ua haujlwm rwb thaiv tsev, hluav taws xob tsis zoo, roj, thiab lwm yam), muab cov ntaub ntawv txhim khu kev qha rau kev ua haujlwm ruaj ntseg.

Koj puas xav kom kuv npaj ib qho lus Askiv ntawm daim ntawv teev npe tseem ceeb rau cov khoom siv ntsuas kev hloov pauv kom yooj yim dua siv siv?
