1. Lub ntsiab rwb thaiv tsev thiab tig-rau-tig rwb thaiv tsev faults ntawm windings
Lub ntsiab rwb thaiv tsev thiab tig-rau-tig rwb thaiv tsev ntawm transformer windings yog cov khoom uas ua rau tsis ua hauj lwm. Cov laj thawj tseem ceeb yog: vim lub sijhawm ua haujlwm dhau mus ntev, cov cua sov tsis zoo, lossis lub neej ua haujlwm ntev, cov rwb thaiv tsev ntawm cov khoom siv hluav taws xob yog cov laus thiab nkig, thiab lub zog hluav taws xob txo qis heev; Kev puas tsuaj ntawm rwb thaiv tsev, thaum muaj qhov hloov pauv ntawm qhov hluav taws xob, cov rwb thaiv tsev yuav tawg; dej nyob rau hauv lub transformer roj yuav zoo heev txo lub rwb thaiv tsev lub zog thiab tsis tuaj yeem tiv taus qhov tso cai voltage, ua rau rwb thaiv tsev tawg; Nyob rau ntawm qhov ntxiv dag zog ntawm qhov siab-voltage winding los yog qhov qis-voltage winding, Vim qhov nthuav dav ntawm tag nrho cov pob rwb thaiv tsev, cov roj hla tau raug thaiv, uas cuam tshuam rau cov cua sov dissipation, thiab cov rwb thaiv tsev winding yog hnub nyoog vim overheating, ua rau muaj kev puas tsuaj thiab luv luv; vim qhov tsis zoo ntawm cov chaw tiv thaiv xob laim, kev puas tsuaj rwb thaiv tsev tshwm sim nyob rau hauv qhov kev txiav txim ntawm atmospheric overvoltage.
2. Lead hlau rwb thaiv tsev txhaum Lub transformer lead hlau yog kos tawm los ntawm lub puab kab noj hniav ntawm lub transformer casing thiab txuas nrog rau sab nraud Circuit Court, thiab cov hlau lead hlau yog txhawb thiab insulated los ntawm lub casing. Vim tias qhov kawg ntawm lub hau ntawm lub casing (General cap) tsis kaw nruj nreem thiab dej nkag mus, lub ntsiab rwb thaiv tsev ntawm cov hlau lead yog puas los ntawm ya raws, los yog cov hlau lead hauv lub tank raug huab cua vim tsis muaj roj ntau. nyob rau hauv lub transformer, ua rau sab hauv flashover, uas yuav ua rau tsis ua hauj lwm ntawm cov hlau lead. .
3. Hlau core rwb thaiv tsev tsis ua hauj lwm Lub transformer core yog ua los ntawm stacked silicon steel los xij, thiab muaj ib tug insulating xim zaj duab xis ntawm cov silicon steel los xij. Vim qhov tsis zoo nruj ntawm cov ntawv silicon steel, cov xim zaj duab xis raug rhuav tshem thiab eddy tam sim no tshwm sim, ua rau hauv zos overheating. Nyob rau hauv tib txoj kev, yog hais tias lub rwb thaiv tsev ntawm cov tub ntxhais screws, qhov hnyav thiab lwm yam khoom uas clamp cov tub ntxhais hlau puas, overheating kuj yuav tshwm sim. Tsis tas li ntawd, yog tias muaj hlau filings los yog vuam slag tshuav nyob rau hauv lub transformer, cov tub ntxhais hlau yuav tsum grounded ntawm ob los yog ntau tshaj cov ntsiab lus, uas yuav ua rau cov tub ntxhais hlau tsis ua hauj lwm.
4. Transformer bushing flashover thiab tawg transformer high-voltage sab (110kV thiab siab dua) feem ntau siv capacitor bushing. Vim tsis zoo porcelain, muaj trachoma los yog tawg; lub capacitor core muaj kev puas tsuaj hauv kev tsim khoom, thiab muaj cov paug tawm dawb hauv; lub bushing tsis kaw. Zoo, muaj roj to; loj casing fouling, thiab lwm yam., flashover thiab tawg yuav tshwm sim.
5. Kais changer txhaum Transformer kais changer yog ib qho ntawm cov txhaum ntawm transformers. Lub kais hloov pauv tau muab faib ua ob hom: kev tswj tsis muaj kev thauj khoom siab thiab kev tswj xyuas lub zog ntawm kev thauj khoom. Cov laj thawj rau kev ua tsis tiav yog: 1) Tsis muaj qhov hloov pauv hloov pauv: vim muaj kev sib cuag mus ntev los ntawm lub siab, yuav muaj lub caij nplooj ntoos hlav tsis txaus thiab lub siab tsis sib xws ntawm cov chais, uas ua rau tus kais hloov pauv. Qhov kev sib cuag zoo ntawm qhov kev sib txuas ntawm tus kais hloov pauv tau txo qis, thiab cov nyiaj plating ntawm qhov sib cuag ntawm qhov kev sib txuas tau raug tshem tawm, ua rau cov kais hloov pauv kom sov thiab puas thaum ua haujlwm; tus kais hloov pauv muaj kev sib cuag tsis zoo, kev sib txuas tsis zoo thiab vuam ntawm cov hlau lead, thiab tsis tuaj yeem tiv taus qhov luv luv tam sim no. Qhov cuam tshuam ua rau lub kais hloov pauv tau hlawv tawm los ntawm qhov luv-circuit tam sim no thiab tsis ua haujlwm; vim kev tswj tsis tau zoo, tus kais hloov pauv tau cuam tshuam lossis ua haujlwm tsis tu ncua, ua rau muaj kev sib tsoo ntawm tus kais dej. 2) On-load kais-changer: Rau transformers nrog on-load kais-changers, roj tank ntawm kais-changer thiab roj tank ntawm transformer feem ntau tsis txuas rau ib leeg. Yog hais tias cov roj tank ntawm tus kais hloov pauv yog luv luv ntawm cov roj, qhov luv luv Circuit Court txhaum ntawm tus kais hloov pauv yuav tshwm sim thaum hloov pauv, uas yuav ua rau cov kais hloov hluav taws kub tawm. Thaum lub sij hawm overhaul ntawm lub casing, lub nqus tsev vacuuming tsis tiav, yog li ntawd cov huab cua nyob nruab nrab ntawm cov ntxaij vab tshaus. Tom qab kev ua haujlwm, nyob rau hauv qhov kev txiav txim siab ntawm qhov hluav taws xob siab, ib feem ntawm qhov paug tshwm sim, thiab txawm tias cov txheej txheej rwb thaiv tsev tau tawg, ua rau muaj kev sib tsoo.
