Cov ntsiab lus tseem ceeb thiab lub voj voog ntawm Transformer Tiv Thaiv Kev Ntsuas

Kev tiv thaiv kev sim ntawm transformers yog ib kauj ruam tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab txhim khu kev lag luam ntawm lub zog hluav taws xob. Nws yog hais txog kev tshuaj xyuas thiab kev sim ua los ntawm cov txheej txheem rwb thaiv tsev, kev ua haujlwm hluav taws xob thiab cov yam ntxwv ntawm cov tshuab hloov pauv thaum lub sijhawm thaum lub tshuab hloov pauv tsis ua haujlwm lossis nyob rau hauv kev npaj kho. Lub hom phiaj yog txhawm rau txheeb xyuas qhov tsis xws luag, ntsuas kev laus, kwv yees kev pheej hmoo tsis ua haujlwm, thiab yog li tiv thaiv hluav taws xob tam sim ntawd.
Cov ntsiab lus tseem ceeb ntawm kev tiv thaiv kev ntsuas hluav taws xob tau muab faib ua ob pawg: kev sim tsis tu ncua thiab hauv online / nyob -kev tshuaj xyuas kab:
1. Lub zog tsis tu ncua -kev xeem tawm (cov khoom tseem ceeb)
Qhov no yog lub cev tseem ceeb ntawm kev tiv thaiv kev ntsuas, uas feem ntau yog ua nrog rau kev npaj kho.
Rwb thaiv tsev yam ntxwv xeem
Rwb thaiv tsev tsis kam thiab nqus piv / polarization Performance index test: Ib txoj hauv kev ua ntej rau kev ntsuam xyuas tag nrho cov rwb thaiv tsev ya raws, av lossis qhov chaw tsis xws luag. Feem ntau, cov rwb thaiv tsev tiv thaiv ntawm high voltage - av, low voltage - av, thiab high voltage - low voltage yog ntsuas.
Dielectric loss factor test: Ntsuas tus nqi tanδ ntawm transformer winding ua ke nrog lub bushing. Nws tuaj yeem ua rau muaj kev cuam tshuam tag nrho xws li kev nqus dej noo, kev laus ntawm cov rwb thaiv tsev, thiab cov roj tsis zoo, thiab yog qhov taw qhia tseem ceeb rau kev ntsuam xyuas cov rwb thaiv tsev.
Roj chromatography tsom xam: Qhov no yog ib qho tseem ceeb tshaj plaws thiab muaj txiaj ntsig kev kuaj mob. Cov roj hluav taws xob rwb thaiv tsev tau raug coj mus tas li los ntawm lub tshuab hloov pauv thiab cov ntsiab lus thiab cov nqi tsim tawm ntawm cov yam ntxwv roj (xws li H₂, CH₄, C₂H₂, C₂H₄, C₂H₆, CO, CO₂) yaj nyob rau hauv kev txheeb xyuas. Raws li txoj hauv kev zoo li "peb- qauv piv", latent faults xws li ib feem tawm, overheating, thiab arc tawm tuaj yeem txiav txim siab.
Transformer Ratio Tester
2. Kev ntsuas hluav taws xob ua haujlwm
Kev ntsuas DC tsis kam: Ntsuas qhov DC tsis kam ntawm txhua theem winding. Xyuas seb cov xov hlau sab hauv ntawm lub winding puas yog welded, cov hlau lead sib txuas yog qhov tseeb, kev sib cuag ntawm tus kais hloov pauv yog qhov zoo, thiab seb puas muaj ib qho luv luv ntawm cov windings.
Ratio test: Txheeb xyuas qhov voltage piv ntawm txhua txoj haujlwm kais. Xyuas seb tus naj npawb ntawm cov lem nyob rau hauv winding puas yog, seb txoj hauj lwm ntawm tus kais hloov pauv hloov, thiab txiav txim seb puas muaj inter-tig los yog inter- txheej luv luv circuits.
Tsis muaj-load tam sim no thiab tsis muaj-load poob kev sim: Qhov kev sim no yog siv los ntsuas qhov sib nqus Circuit Court kev ua tau zoo ntawm cov tub ntxhais, qhov rwb thaiv tsev ntawm cov ntaub ntawv silicon steel, thiab seb puas muaj qhov luv luv ntawm windings (uas tuaj yeem ua rau muaj kev poob qis).
Luv luv- Circuit Court impedance thiab load poob test: Xyuas seb cov windings puas tau deformed los yog hloov (piv nrog lub Hoobkas lossis cov ntaub ntawv keeb kwm). Kev hloov pauv hauv luv luv -circuit impedance yog cov cim qhia txog kev kuaj xyuas winding deformation.
3. Kev kuaj mob tshwj xeeb
Winding zaus teb tsom xam: Txoj kev zoo tshaj plaws rau kev kuaj xyuas winding deformation (xws li kev hloov pauv thiab kev tsis sib haum xeeb los ntawm luv luv -circuit electrodynamic rog). Los ntawm kev sib piv cov kev ntsuas nkhaus los ntawm kev xeem dhau los, qhov℃ntawm deformation tuaj yeem txiav txim siab raug.
Kev kuaj ib nrab tso tawm: Qhov kev sim no kuaj pom cov cim tso tawm ib nrab hauv cov rwb thaiv tsev, ua kom pom kev ntxov ntawm cov rwb thaiv tsev tsis zoo. Nws tuaj yeem ua tau los ntawm kev siv hluav taws xob ntawm -site.
Fais fab zaus tiv taus qhov ntsuas hluav taws xob: Qhov kawg txoj hauv kev rau kev ntsuas lub ntsiab rwb thaiv tsev lub zog. Nws yog ua nyob rau hauv lub zog hluav taws xob zaus high voltage rau 1 feeb los xyuas seb lub rwb thaiv tsev puas tuaj yeem tiv taus lub overvoltage thaum lub sijhawm ua haujlwm. Qhov kev sim no feem ntau yog ua tom qab lwm qhov kev sim uas tsis yog - puas tau dhau lawm.
Packing test: Ua dielectric poob thiab capacitance tests ntawm lub capacitive bushing. Cov kev hloov pauv hauv lub peev xwm tuaj yeem qhia tau tias muaj kev ya raws lossis ua txhaum.
4. Kev ua haujlwm roj thiab kev sim tshuaj
Rwb thaiv tsev roj hluav taws xob kuaj lub zog: Ntsuas qhov tawg ntawm cov roj los txiav txim nws lub zog rwb thaiv tsev.
Kev sim rau micro- dej cov ntsiab lus hauv cov roj: Cov dej tuaj yeem txo qhov kev ua haujlwm ntawm rwb thaiv tsev thiab ua kom muaj kev laus.
Kev ntsuam xyuas cov ntsiab lus roj hauv cov roj: Cov ntsiab lus roj ntau dhau cuam tshuam rau kev rwb thaiv tsev thiab cua sov, thiab tuaj yeem ua rau muaj paug hauv zos.
II. Kev soj ntsuam online thiab kuaj nyob
Tsis muaj kev cuam tshuam rau kev ua haujlwm, kev saib xyuas cov khoom siv hauv lub sijhawm tiag tiag lossis tsis tu ncua yog ib qho tseem ceeb ntxiv rau cov kev xeem tsis tu ncua.
Kev tshuaj xyuas online ntawm cov pa yaj hauv cov roj: tiag tiag -lub sijhawm lossis kev saib xyuas cov roj yam tsis tu ncua kom ua tiav qhov kev twv ua ntej.
Kev saib xyuas hauv online ntawm ib feem ntawm qhov tso tawm: Tsis tu ncua saib xyuas cov dej ntws tawm hauv lub tshuab hloov pauv.
Core grounding tam sim no saib xyuas: Ntsuas qhov tam sim no ntawm cov xaim hauv av ntawm cov tub ntxhais los txiav txim seb puas muaj ntau yam -point grounding txhaum.
Infrared thermal imaging soj ntsuam: Tsis tu ncua ntsuas kub infrared ntawm bushing pob qij txha, lub thawv, cov khoom cua txias, thiab lwm yam., txhawm rau txheeb xyuas qhov tsis xws luag.
Ultrasonic/frequency detection: Tshawb xyuas lub suab nthwv dej lossis electromagnetic signals generated los ntawm ib nrab paug.
III. Lub Sijhawm Xeem
Raws li cov qauv xws li "Cov Txheej Txheem Kev Tiv Thaiv Hluav Taws Xob Hluav Taws Xob", lub voj voog xeem feem ntau yog:
Tshiab muab tso rau hauv kev ua haujlwm: Ua ntej commissioning, 1 lub hlis tom qab commissioning, thiab 1 xyoo tom qab commissioning.
