Transformer Cov Khoom Siv Hauv Kev Ua Yuam Kev thiab Cov Ntsiab Lus
1. Cov yam ntxwv ntawm Transformer Tub Ntxhais Txhaum
Tus hloov pauv ntawm cov tub ntxhais ua txhaum tshwm sim thaum tus Cauv hloov pauv mus ua qhov teeb meem hauv av, ua rau muaj cov teeb meem kev ua haujlwm. Cov yam ntxwv thawj ntawm qhov kev txhaum no suav nrog:
Cov teb tsis sib nqus: qhov txhaum tsim ib qho kev sib nqus sib nqus hauv cov tub ntxhais hloov pauv, uas tuaj yeem ua rau hauv zos overheating efferman.
Cov tub ntxhais kawm poob qis: grounding kev ua yuam kev tuaj yeem ua rau muaj EDDY muaj ntau yam hauv cov tub ntxhais, ua rau muaj kev puas tsuaj ntau rau cov khoom tseem ceeb.
Kev co thiab lub suab nrov: ib qho tseem ceeb hauv av ua txhaum cai tuaj yeem ua rau cov neeg siv tshuab deeg thiab lub suab tsis sib xws vim yog cov tub rog tsis sib xws ntawm cov tub ntxhais.
Overvoltage lossis voltage Imbalance: Qhov txhaum yuav ua rau cov faib hluav taws xob tsis sib xws, ua rau muaj kev kub ntxhov lossis theem, cuam tshuam rau tag nrho cov hluav taws xob.
Tripping kev tiv thaiv rov qab: kev ua txhaum yuav ua rau muaj kev tiv thaiv lossis kev tiv thaiv ntau dhau los), ua rau lub txee sib hloov lossis tag nrho cov kab ke.
Harmonic distortion: ib qho kev txhaum ntawm av yuav ua rau muaj kev sib txawv hauv cov hluav taws xob, uas tuaj yeem cuam tshuam cov cuab yeej rhiab, uas tuaj yeem txuas nrog lub network.
2. Cov teeb meem ntawm cov tub ntxhais ua yuam kev
Cov laj thawj tseem ceeb ntawm kev hloov pauv tub ntxhais yuam kev sib dhos xws li:
Rwb thaiv tsev rhuav tshem: Ntev sijhawm, rwb thaiv tsev ntawm lub transformer lub core lossis woodings yuav ua rau kev laus, kev kub thiab kub, ua rau ib qho chaw luv.
Kev puas cuab yeej puas: kev puas tsuaj rau lub cev rau tus hloov pauv, xws li thaum lub sij hawm teeb tsa lossis tsheb thauj mus los, tuaj yeem ua rau grounding.
Txhaum kev tsim: Kev tsim khoom tsis xws luag, suav nrog rulishs txom nyem lossis kev sib dhos tsis raug cai, yuav ua rau muaj kev tsis txaus siab.
Ib puag ncig cov ntsiab lus: Raug nthuav dav rau ib puag ncig ib puag ncig (piv txwv li, hluav taws xob surges, lossis dej nyab) tuaj yeem ua rau ua txhaum hauv lub transformer core.
3. Nrhiav txoj hauv kev
Txhawm rau nrhiav cov tub ntxhais ua yuam kev, ob peb txoj hauv kev tuaj yeem siv:
Kev soj ntsuam txuas ntxiv: Siv lub plab zom mov lossis rwb thaiv tsev tsis kam mus kuaj xyuas kom tau txuas ntxiv ntawm tus hloov pauv thiab hauv av.
Kev tiv thaiv sib txawv: Kev tiv thaiv kev tiv thaiv sib txawv tuaj yeem tshawb pom tsis txaus hauv qhov tam sim no ntawm thawj lub ntsej muag thiab lub qhov txhaum.
Kev ua txhaum kev soj ntsuam kev soj ntsuam cov system: INSALSION SATOR cov tshuab uas tuaj yeem txuas ntxiv saib xyuas cov hloov pauv ntawm cov ntaub ntawv ntawm kev ua txhaum.
Kev co kev ntsuas: Kev saib xyuas cov suab lossis txawv suab los ntawm cov hloov pauv yuav qhia tawm cov teeb meem kho tshuab los ntawm cov chaw ua haujlwm hnyav.
Thermal ua duab: cov koob yees duab thermal tuaj yeem siv los kuaj cov hotspots uas yuav qhia tau tias muaj kev kub ntxhov dhau los vim yog av.
4. Kev daws rau cov tub ntxhais ua yuam kev
Thaum cov tub ntxhais ua txhaum yog kuaj pom, ntau cov kev daws teeb meem tuaj yeem ua los daws qhov teeb meem:
Cov rwb thaiv tsev tseem ceeb lossis hloov chaw: Yog tias tus tseem ceeb rwb thaiv tsev muaj degraded, nws yuav tsum tau kho lossis hloov los tiv thaiv kev ua txhaum ntxiv.
Kev teeb tsa ntawm cov av hauv av relays: av tiv thaiv kev tiv thaiv cov khoom siv tsim nyog yuav tsum tau raug ntsia kom pom tseeb thiab cais tawm yuam kev sai. Cov kev tawg no tuaj yeem tiv thaiv kev puas tsuaj rau lub transformer thiab lwm yam.
Kev saib xyuas thiab tshuaj xyuas: kev soj ntsuam ib txwm thiab kev soj ntsuam kom huv si, suav nrog kev kuaj mob rwb thaiv tsev, tuaj yeem txheeb xyuas cov teeb meem muaj peev xwm ua ntej lawv ua txhaum.
Txhim kho cov txheej txheem txheej txheem: ua kom paub meej tias qhov hloov pauv hauv av yog tsim thiab tswj kom tiv thaiv kom txhob muaj kev yuam kev ntawm cov tub ntxhais.
Txhim kho transformer tsim: nyob rau qee kis, nws yuav tsim nyog los txhim kho cov kev pheej hmoo ntawm qhov tshwm sim, thiab txhim kho kev ua txhaum qhov muaj peev xwm.
Kev tuav kom tsim nyog thiab kev teeb tsa: thaum lub sijhawm thauj, kev teeb tsa, kev saib xyuas, kev saib xyuas yuav tsum tau coj mus rau qhov kev puas tsuaj ntawm lub cev, uas tuaj yeem ua rau cov tub ntxhais ua yuam kev.
5. Xaus
Transformer tub ntxhais hauv paus ua txhaum yuav muaj qhov cuam tshuam tseem ceeb ntawm kev ua tau zoo thiab kev nyab xeeb ntawm cov hluav taws xob hluav taws xob. Nrhiav kom tau txais kev kho kom sai, thiab kev saib xyuas kom zoo yog qhov tseem ceeb kom txo cov kev pheej hmoo cuam tshuam nrog cov kev ua txhaum no. Kev tshawb xyuas ib txwm, kev siv cov kev txhaum cai txiav txim siab, thiab kev ua raws li kev teeb tsa cov txheej txheem tuaj yeem txo cov kev ua txhaum.
