Raws li cov cuab yeej tseem ceeb hauv lub zog hluav taws xob, cov khoom siv hluav taws xob ua haujlwm tseem ceeb ntawm AC voltage hloov dua siab tshiab thiab lub zog xa mus. Txawm hais tias nws yog kev tsim khoom lag luam lossis lub neej niaj hnub, kev nyab xeeb ntawm kev hloov pauv yog qhov tseem ceeb. JINSHANMEN TECHNOLOGY CO., LTD, ua ib lub chaw tsim khoom ntawm cov khoom siv hluav taws xob, feem ntau tsim cov roj immersed fais fab transformers, qhuav -hom fais fab transformers, roj immersed peb-dimensional coiled fais fab transformers, thiab lwm yam khoom, nrog rau siab - zooroj immersed faib transformerthiab 3 theem nqis transformer. Raws li ntau xyoo ntawm kev tsim khoom thiab ntawm - qhov kev paub dhau los ntawm qhov chaw, kab lus no tshuaj xyuas qhov ua txhaum ntawm cov hloov pauv, tshawb nrhiav lawv cov laj thawj, thiab muab cov kev daws teeb meem los pab cov phooj ywg hauv kev lag luam kom txo qhov kev poob txhaum.
1. Winding Fault: Lub Core Hidden Danger cuam tshuam rau kev ua haujlwm
Winding yog lub hauv paus tseem ceeb ntawm transformers, thiab nws cov faults feem ntau muaj xws li tig - mus rau -tig luv luv Circuit Court, winding grounding, theem - mus rau -theem luv luv Circuit Court, disconnection thiab sib txuas vuam tsis ua hauj lwm. Rau cov roj immersed tis transformer, winding faults yog feem ntau ze ze rau rwb thaiv tsev roj zoo thiab kub dissipation efficiency. Cov laj thawj tshwj xeeb thiab kev kho mob yog raws li hauv qab no:
Ua rau tsis ua hauj lwm:
① Rwb thaiv tsev puas sab laug thaum tsim khoom lossis txij nkawm;
② Tsis zoo cua sov dissipation los yog ntev - lub sij hawm overload thaum lub sij hawm ua hauj lwm, ua rau rwb thaiv tsev laus;
③ Cov txheej txheem tsim khoom tsis zoo, tsis tuaj yeem tiv taus luv luv - cuam tshuam hauv Circuit Court, ua rau winding deformation;
④ Winding damp, rwb thaiv tsev nthuav dav thaiv cov roj raws, ua rau hauv zos overheating;
⑤ Rwb thaiv tsev roj deterioration vim dej sib tov, txo cov rwb thaiv tsev.
Fault phenomenon: Transformer overheating, nce roj kub, me ntsis nce nyob rau hauv lub hwj chim mov sab tam sim no, unbalanced DC tsis kam ntawm txhua theem. Rau 3 theem kauj ruam down transformer, theem imbalance yuav pom tseeb dua. Hloov me ntsis - mus rau - tig luv luv yuav ua rau muaj kev tiv thaiv roj; Cov mob hnyav yuav ua rau muaj kev tiv thaiv sib txawv lossis kev tiv thaiv overcurrent.
Kev ntsuas kev kho mob: Thaum pom qhov ua txhaum ntawm qhov tsis sib haum, cov tub ntxhais yuav tsum tau nqa mus kuaj. Ua ntej, ntsuas qhov DC tsis kam ntawm txhua theem winding rau kev sib piv; ces xyuas cov txheej txheem rwb thaiv tsev. Rau kev puas tsuaj me me, hloov cov khoom siv rwb thaiv tsev hauv zos; rau loj deformation los yog luv luv Circuit Court, hloov lub winding thiab hloov lub rwb thaiv tsev roj ntawm cov roj immersed tis transformer.
2. Bushing Fault: Yooj yim Ignored Sab Nraud Hazard
Bushing yog qhov tseem ceeb ntawm kev sib txuas ntawm lub tshuab hluav taws xob sab hauv thiab sab nraud, thiab nws cov kev ua txhaum feem ntau suav nrog kev tawg, flashover thiab roj to. Qhov kev ua txhaum no tsis tsuas yog cuam tshuam rau kev ua haujlwm ntawm rwb thaiv tsev xwb tab sis kuj tuaj yeem ua rau muaj kev sib tsoo thib ob. Rau 3 theem kauj ruam down transformer siv nyob rau hauv industrial lub sij hawm, bushing txhaum yog feem ntau yuav tshwm sim vim hnyav ua hauj lwm ib puag ncig.
Ua rau tsis ua hauj lwm:
① Tsis zoo sealing ua rau rwb thaiv tsev damp thiab roj to;
② Kev teeb tsa tsis raug ntawm kev ua pa lossis kev kho tsis raws sij hawm ntawm kev nqus dej noo;
③ Porcelain tsis xws luag xws li xuab zeb qhov los yog tawg nyob rau hauv siab -voltage capacitor bushings;
④ Cov teeb meem hauv kev tsim cov tub ntxhais capacitor, ua rau muaj kev tso tawm sab hauv;
⑤ Cov fouling hnyav ntawm bushing nto.
Kev ntsuas kev kho mob: tsis tu ncua ntxuav lub bushing nto kom tshem tawm fouling; xyuas qhov kev ua tau zoo ntawm kev sib khi thiab hloov lub nplhaib sib khi hauv lub sijhawm. Rau cov bushings nrog cov plooj (porcelain defects) lossis sab hauv, lawv yuav tsum tau hloov tam sim ntawd kom tsis txhob tawg. Rau cov roj immersed tis transformer, nws yog ib qho tsim nyog los xyuas cov roj theem hauv lub sij hawm tom qab hloov bushing los tiv thaiv cov roj tsis txaus.
3. Core Fault: Internal Overheating Trigger
Cov tub ntxhais yog cov sib nqus Circuit Court ib feem ntawm lub transformer, thiab nws cov rwb thaiv tsev tsis ua hauj lwm yog lub ntsiab ua rau cov tub ntxhais faults. Qhov kev ua txhaum no tau muab zais, thiab yog tias nws tsis ua haujlwm raws sijhawm, nws yuav ua rau muaj cua sov hauv zos thiab txawm tias cov tub ntxhais yaj. JINSHANMEN TECHNOLOGY nruj me ntsis tswj cov txheej txheem tsim khoom hauv kev tsim cov roj immersed tis transformer thiab 3 theem kauj ruam down transformer kom txo tau qhov tshwm sim ntawm xws li faults.
Ua rau tsis ua hauj lwm:
① Rwb thaiv tsev puas ntawm silicon steel los xij ua rau hauv zos overheating thiab melting;
② Rwb thaiv tsev puas ntawm cov tub ntxhais clamping bolts tsim luv luv ntawm bolts thiab silicon steel los xij;
③ Residual vuam slag ua rau ob -point grounding ntawm cov tub ntxhais;
④ Hauv zos sib nqus flux to ntawm cov tub ntxhais thiab winding clips ua rau overheating.
Kev ntsuas kev kho mob: Thaum xav tias muaj qhov yuam kev tseem ceeb, cov tub ntxhais yuav tsum tau nqa mus kuaj. Ua ntej, ua ib qho kev tshuaj ntsuam xyuas los xyuas cov vuam slag residues thiab bolt rwb thaiv tsev; Tom qab ntawd ntsuas qhov rwb thaiv tsev ntawm silicon steel los xij nrog DC voltage thiab ammeter txoj kev. Rau kev puas tsuaj me me, xim tuaj yeem siv rau kev kho; rau kev puas tsuaj loj, cov ntawv silicon steel lossis cov rwb thaiv tsev yuav tsum tau hloov.
4. Gas Protection Fault: Safety Alarm Signal
Gas kev tiv thaiv yog lub ntsiab tiv thaiv ntawm transformers, nrog lub teeb roj ua rau cov teeb liab thiab hnyav roj ua rau tripping. Cov cuab yeej tiv thaiv no yog qhov tseem ceeb tshwj xeeb rau cov roj immersed tis transformer, raws li nws tuaj yeem tshawb xyuas qhov tsis raug sab hauv xws li roj decomposition.
Ua rau kev ua:
① Cua nkag vim tsis zoo sealing ntawm cov roj lim, roj filling thiab cua txias tshuab;
② Roj theem poob vim qhov kub thiab txias los yog roj to, los yog ib tug me me ntawm cov roj yog tsim los ntawm me me txhaum;
③ Ua los ntawm luv luv - Circuit Court txhaum;
④ Secondary Circuit Court tsis ua hauj lwm ntawm kev tiv thaiv ntaus ntawv.
Kev ntsuas kev kho mob: Tom qab lub teeb roj ua haujlwm, tshawb xyuas qhov hloov pauv tam sim ntawd thiab ua cov qauv ntsuas roj yog tias tsis pom qhov txawv txav. Tom qab hnyav roj mus txawv tebchaws, thawj zaug muab tso rau hauv lub standby transformer (xws li lub3 theem theem down transformernpaj los ntawm tus neeg siv), tom qab ntawd tshawb xyuas qhov tawg - qhov rooj pov thawj, vuam seam thiab plhaub deformation, thiab thaum kawg sim cov nplaim taws ntawm cov pa. Nws yog nruj me ntsis txwv tsis pub rov kaw yam tsis muaj kev tshawb nrhiav.
5. Kev Ua Haujlwm Thaum Muaj Xwm Ceev: Tuav thiab Hluav Taws Xob
Transformer tripping thiab hluav taws kub yog qhov teeb meem ceev, thiab kev tuav kom raug tuaj yeem txo qhov kev poob qis.JINSHANMEN TECHNOLOGYmuab kev taw qhia kev siv rau cov neeg siv thaum muab siab - transformers zoo, pab cov neeg siv nrog xwm ceev ceev.
Tsis siv neeg tripping tuav: Tom qab tripping, thawj zaug kho hom kev ua haujlwm los ntawm kev muab tso rau hauv lub standby transformer; tom qab ntawd xyuas qhov kev tiv thaiv thiab qhov teeb meem txhaum cai. Rau tripping tshwm sim los ntawm phau ntawv misoperation los yog pom tseeb misprotection, mus sib hais hwj chim kis tau tus mob yuav ua tau ib zaug nrog kev pom zoo; rau tripping tshwm sim los ntawm kev tiv thaiv tseem ceeb xws li kev sib txawv thiab cov pa hnyav, kev soj ntsuam kom ntxaws thiab ntsuas hluav taws xob yuav tsum tau ua ua ntej xa hluav taws xob.
Kev tuav hluav taws: Tam sim ntawd txiav tawm lub hwj huam mov thiab muab tso rau hauv lub standby transformer; nres lub tshuab cua txias. Yog tias cov roj hlawv rau saum lub hau, qhib qhov kev sib tsoo roj ntws valve mus rau qhov chaw tsim nyog; yog tias hluav taws kub hauv qhov tshwm sim, tsis txhob tso roj kom tsis txhob tawg. Siv cov hmoov qhuav los yog ua npuas dej tua hluav taws los tua hluav taws, thiab hu rau lub chaw tua hluav taws yog tias tsim nyog.
