Kev hloov pauv ntawm winding deformation

 

Lub transformer winding deformation yog hais txog lub luag hauj lwm ntawm winding los ntawm mechanical zog thiab hluav taws xob fais fab, thiab qhov luaj li cas thiab cov duab ntawm lub winding tau undergone hloov irreversible thiab feem ntau manifested raws li kev hloov nyob rau hauv axial thiab radial qhov ntev, lub cev hloov, winding, nruas hnab, thiab inter-tig luv luv circuits.

 

 

• 1. Short-circuit txhaum tam sim no cuam tshuam.
• 2. Nws raug tsoo thaum lub sijhawm thauj mus los, kev teeb tsa, lossis dai.
• 3. Ntau lub sijhawm ua kua.
• 4. Lub winding tsis txaus.

 

Thaum lub sij hawm ua hauj lwm ntawm lub hwj chim transformer, qhov cuam tshuam ntawm ntau yam luv luv-circuit tam sim no yog inevitable, tshwj xeeb tshaj yog thaum lub transformer tawm los yog luv luv-circuit tsis ua hauj lwm nyob rau hauv cov cheeb tsam ze. Qhov loj luv luv-circuit tam sim no yuav ua rau lub transformer winding raug kev txom nyem hluav taws xob ntau (thaum nws yog ib txwm ua hauj lwm Dozens mus rau pua pua ntawm lub sij hawm) thiab winding ntawm lub winding sharply. Thaum qhov kub thiab txias, lub zog txhua yam ntawm cov xov hlau yuav me dua, thiab lub zog hluav taws xob yuav ua kom puas lossis deform lub winding. Short-circuit txhaum tam sim no yog qhov tseem ceeb tshaj plaws sab nraud ua rau transformer winding deformation.

 

 

Cov laj thawj sab nraud:

 

1. Lub transformer yog unavoidable los dais ntau yam luv luv-circuit shocks thaum lub sij hawm ua hauj lwm, uas lub short-circuit ntawm exports rau lub transformer yog tshwj xeeb tshaj yog loj. Txawm hais tias lub Circuit Court breaker tuaj yeem tshem tawm qhov tsis ua haujlwm luv luv ntawm lub voj voog, feem ntau cov cuab yeej tsis siv neeg tsis txav mus los vim qee qhov laj thawj, yog li cov kauj ruam transformer yuav ua rau coil deformation nyob rau hauv ib lub sij hawm luv luv nyob rau hauv qhov kev txiav txim ntawm luv luv-circuit tam sim no kub thiab hluav taws xob. Nws yuav ua rau luv luv ntawm cov theem thiab hlawv lub winding.

 

2. Lub tshuab hluav taws xob kuj tseem tuaj yeem cuam tshuam los ntawm kev sib tsoo thaum lub sijhawm thauj khoom thauj mus los ua kom muaj kev cuam tshuam, kev sib tsoo, kev hloov pauv, kev xoob, thiab lwm yam tshwm sim.

 

Yog vim li cas:

 

1. Cov chaw tsim khoom tsis xav txog qhov tsim nyog tus cwj pwm kev nyab xeeb thaum tsim, yog li hais tias kev ruaj ntseg hais tias qhov tseeb winding cuam tshuam tsis tuaj yeem ua tau raws li qhov cuam tshuam ntawm luv luv tam sim no ntawm qhov chaw.

 

2. Vim tias cov txheej txheem tsim khoom tsis zoo, qhov tho txawv thiab sib dhos sib dhos yog qhov loj heev, thiab cov qauv kev txhawb nqa hauv cov winding hauv winding yog tsis siv.

 

3. Lub tshav pob winding los ntawm qhov tsis sib xws uas tshwm sim los ntawm tus ciam teb ntawm lub winding tsis yog ib tug ncej symmetrical magnetic teb, uas ua rau lub spokes rau winding yuav uniformly faib nyob rau hauv cov kev taw qhia ntawm lub voj voog. Nyob rau hauv luv luv Circuit Court, lub weakly txhawb bar ncua sij hawm yog thawj zaug poob stability.

 

4. Ntau qhov kev sib tsoo luv luv tuaj yeem ua rau deformation tsub zuj zuj ntawm winding. Nyob rau hauv lub neej yav tom ntej, ib tug luv luv-circuit quab yuam yuav tshaj qhov tiag tiag affordability ntawm cov qauv kev them nyiaj yug, uas ua rau ib tug poob ntawm stability deformation.

 

 

 

 

1. Qhov kev ncua deb ntawm cov rwb thaiv tsev hloov thiab cov khoom rwb thaiv tsev puas lawm, uas ua rau cov paug hauv zos. Thaum lub thunderbolt siv rau overvoltage, nws yuav tshwm sim nyob rau hauv inter-turboples thiab ncuav. Kev rwb thaiv tsev thiab kev sib tsoo tawg vim yog lub sijhawm ntev ntawm kev tso tawm hauv zos.

 

2. Lub tshuab ua haujlwm ntawm lub winding yog txo. Thaum muaj kev sib tsoo luv luv dua, nws yuav tsis ris lub zog hluav taws xob loj thiab kev puas tsuaj.

 

 

1. Kev tshawb fawb txog lub peev xwm luv luv ntawm transformers. Lub zog hluav taws xob uas tsim los ntawm qhov luv-circuit tam sim no yog ib qho tseem ceeb ua rau deformation. Yog li txhawm rau tiv thaiv deformation ntawm winding thiab txhim kho kev ntseeg siab ntawm kev ua haujlwm ntawm transformer. Ua ntej ntawm tag nrho cov, peb yuav tsum pib nrog lub peev xwm los daws cov transformer kom zam luv luv circuits. Kev tshawb fawb txog kev siv tshuab lub zog ntawm txoj kev tsis tuaj yeem nyob ntawm qhov kev xam pom thiab kev suav ntawm cov qauv me me. Peb yuav tsum xyuam xim rau qhov kev ntsuam xyuas luv luv.

 

2. Xaiv qhov siab ntawm lub winding kom raug. Lub transformer puas tuaj yeem sawv qhov cuam tshuam ntawm lub zog hluav taws xob luv luv? Tsuas yog cov yam ntxwv xws li lub zog txhua yam, kev ua haujlwm rwb thaiv tsev zoo, winding zoo ntawm winding, thiab winding cov qauv ntawm cov qauv, qhov nruj ntawm winding plays lub luag haujlwm tseem ceeb. Me me. Lub siab ntawm winding yuav tsum tsis txhob loj heev. Thaum lub siab nruj tshaj li ib qho kev tso cai, cov qauv nruj yuav tsum deformed. Kev siv zog cia yog txo, uas txo qhov cuam tshuam lub peev xwm tiv thaiv hluav taws xob luv luv.

 

3. Txhim khu qhov chaw. Qhov kev txhim khu kev qha ntawm lub cev yog tus yuam sij rau kev tiv thaiv kev txav chaw thaum lub sijhawm thauj mus los. Yog li ntawd, nws tsis tuaj yeem lav qhov kev puas tsuaj hauv zos los tiv thaiv lub zog ntawm lub tshuab hloov pauv winding, thiab cov pob hauv kev thauj mus los hauv cov qauv tsim. Cov cuab yeej siv lub cev tso siab tau yuav tsum tau siv.

 

4. Txhim kho qhov kev tiv thaiv luv luv thiab ua tib zoo saib xyuas qhov teeb meem ntawm kev rov kaw lub qhov rooj. Kev tiv thaiv tsis kam yog ib qho ntawm cov laj thawj tseem ceeb uas ua rau transformer winding deformation kom txwv tsis pub luv luv tam sim no, tshem tawm cov kev tiv thaiv ntawm "qhov chaw tuag", thiab txiav sai sai rau lub transformer. Nce, thiab tiv thaiv lub transformer yam tsis muaj kev puas tsuaj nyob rau hauv txoj kev zoo. Lub transformer yuav tsum luv luv kom ntau li ntau tau.

 

5. Txhim kho qhov deformation xyuas ntawm lub winding thiab kho nws raws sijhawm. Lub launching winding xeem tshuab muab cov kev txiav txim tseem ceeb txhais tau tias kom txuas ntxiv khiav lub transformer tom qab muaj kev cuam tshuam luv luv. Tom qab luv luv Circuit Court ntawm kev xa tawm loj transformer, qhov kev xeem winding yuav tsum tau ua nrog cov lus teb thawj zaus muab los ntawm cov chaw tsim khoom. Lub hauv paus kev txiav txim rau lub deformation thiab deformation ntawm winding yuav tsum tsis txhob tso cai.

 

6. Siv cov kev ntsuas kom ua tau zoo los txo cov caij nyoog luv luv hauv lub npav. Thaum cov niam txiv kab yog luv-circuited, niam txiv mov transformer yuav tsum tau muab tshem tawm sai li sai tau. Nyob rau tib lub sijhawm, ua ntej lub tsheb npav luv luv, lub Hoobkas tsis tuaj yeem nqis peev hauv lub tsheb npav txhaum cai.

 

7. Cov lus teb zaus ntawm kev hloov pauv loj thaum lub sijhawm ua haujlwm yuav tsum muab piv nrog cov lus teb cov lus teb zaus tom qab kev sib tsoo. Lub degree ntawm deformation ntawm lub transformer winding tsim nyog. Rau cov transformers uas pom qhov winding deformation ntawm winding los ntawm lub suab zaus, lawv yuav tsum tau xyuas thiab khaws cia nyob rau hauv lub sij hawm luv tshaj nyob rau hauv lub shortest lub sij hawm.

 

8. Configure fault recording wave online surveillance device. Rau transformers ntawm 110kV (66kV) thiab siab dua voltage theem, yuav tsum muaj ib tug txhaum cov ntaub ntawv yoj xyuas cov cuab yeej, mastering short-circuit txhaum tam sim no thiab lub sij hawm ntawm faults, thiab siv los txiav txim lub deformation ntawm winding.
