Koj puas paub ob peb yam ua rau Transformer tsis ua haujlwm
(1) Circuit Court tsis ua haujlwm
Lub Circuit Court txhaum ntawm lub transformer feem ntau yog hais txog luv luv Circuit Court ntawm qhov hluav taws xob ntawm lub transformer, luv luv Circuit Court ntawm cov hlau lead los yog winding mus rau hauv av nyob rau hauv lub transformer, thiab qhov tshwm sim ntawm qhov txhaum vim yog luv luv Circuit Court ntawm cov theem. . Qhov tseeb, hom kev txhaum no yog ib qho teeb meem tshwm sim ntawm ntau qhov teeb meem txhaum cai ntawm lub hwj chim transformers, thiab muaj ntau qhov tseeb ntawm qhov txhaum. Rau luv luv-circuit ntawm transformer ntawm qhov hluav taws xob tsawg-voltage, thiaj li yuav daws tau qhov teeb meem, cov windings feem ntau yog hloov ntawm qhov chaw txhaum. Thaum qhov txhaum loj heev, txhua qhov windings yuav tsum tau hloov raws li qhov tsim nyog, thiaj li txo qis qhov tshwm sim ntawm qhov txhaum ntau li ntau tau thiab txo qhov ua rau. Kev lag luam loj thiab tus kheej thiab cov khoom poob los ntawm lub hwj chim tsis ua hauj lwm, yog li ntawd, yuav tsum tau ua tib zoo saib xyuas qhov no. [4]
(2) Winding tsis ua hauj lwm
Lub winding faults tuaj yeem muab faib ua hom hauv qab no kom ntxaws: cov pob qij txha tsis tshua muaj kev sib tsoo, theem-rau-theem short-circuit teeb meem, tig-rau-tig luv-circuits, winding av faults, thiab lwm yam. Kev tshuaj xyuas thiab kev txiav txim siab. Yog vim li cas rau cov kev ua txhaum saum toj no tuaj yeem raug sau tseg: cov rwb thaiv tsev ntawm lub transformer muaj teeb meem; sundries nyob rau hauv windings, laus insulators; tsis txaus ua hauj lwm lub zog ntawm lub transformer; teeb meem nrog cov windings vim deformation: cov windings raug cuam tshuam los ntawm dej vapor; qhov kub ntawm lub transformer siab. [4]
(3) Transformer roj seepage txhaum
Transformer roj leakage txhaum yog qhov txhaum ntau tshaj plaws hauv tag nrho lub hwj chim transformer txhaum. Transformer roj to tsis ua hauj lwm yuav piav qhia tau hais tias lub hwj chim transformer roj to yuav ua rau qee yam teeb meem tom qab, xws li ib puag ncig muaj kuab paug rau huab cua nws tus kheej, thiab kuj tseem yuav ua rau cov khoom siv pov tseg ntau, uas yuav ua rau cov nqi khiav lag luam zoo heev. , yog li nce Lub economic siab thiab kev ua lag luam tsis kam ntawm cov lag luam. Raws li kev nyab xeeb kev nyab xeeb zais cia, qhov teeb meem no yuav cuam tshuam rau kev nyab xeeb thiab ruaj khov ntawm lub zog hloov hluav taws xob, thiab thaum muaj xwm txheej hnyav, nws yuav ua rau tsis muaj peev xwm ntawm cov tshuab thiab khoom siv. Nws tseem yuav tsum raug sau tseg tias qhov tsis ua haujlwm kuj tseem yuav cuam tshuam rau kev pabcuam zoo ntawm cov tuam txhab hluav taws xob, thiab yuav muaj kev cuam tshuam loj rau kev pabcuam kev nyab xeeb thiab kev tshawb fawb rau cov neeg siv khoom siv hluav taws xob. [4]
(4) Qhov kub ntawm qhov sib koom ua ke thiab qhov ua txhaum loj npaum li cas
Qhov kub ntawm qhov sib koom ua ke thiab siab npaum li cas qhov kev sib koom ua txhaum yog hais txog qhov sib koom ua ke tam sim no ntawm lub transformer. Thoob plaws hauv kev tsim ntawm lub transformer, tam sim no-nqa pob qij txha ntawm lub transformer yeej ib txwm xav tias tseem ceeb heev luag hauj lwm. Kev tsom xam thiab cov ntsiab lus ntawm kev sib tsoo hluav taws xob tuaj yeem txiav txim siab: qhov kev sib txuas tsis ruaj khov ntawm cov pob qij txha tam sim no ntawm lub transformer ua rau qhov kub thiab txias ntawm cov pob qij txha nce nrawm, txawm tias dhau ntawm qhov hluav taws xob ntawm qhov sib koom ua ke, uas ua rau kev sib koom ua ke. hlawv tawm, uas cuam tshuam rau kev nyab xeeb thiab ruaj khov ntawm lub zog transformer. Cov teeb meem no tau ua lub suab ceeb toom rau cov tuam txhab hluav taws xob hluav taws xob ua haujlwm rau kev nyab xeeb fais fab rau yav tom ntej. Txhawm rau kom txo tau qhov tshwm sim ntawm kev nyab xeeb zoo li no thiab tsis txhob muaj kev nyab xeeb hluav taws xob xwm txheej tshwm sim los ntawm qhov kub thiab txias ntawm cov pob qij txha, nws yog ib qho tsim nyog rau cov neeg ua hauj lwm saib xyuas hluav taws xob thiab cov neeg ua hauj lwm saib xyuas qhov kub thiab txias ntawm cov khoom siv tam sim no. transformer thaum lub sij hawm ib txwm soj ntsuam thiab tu ua hauj lwm. Qhov kub ntawm qhov sib koom ua ke hloov pauv hauv cov nqi ib txwm muaj, txhawm rau ua kom muaj kev nyab xeeb thiab ruaj khov ua haujlwm ntawm lub zog transformer.
