Cov kev ua yuam kev tsis zoo thiab ntsuas ntawm lub thawv hom hloov chaw
1. Kev ntsuas kub ntawm kev kho rau lub thawv hloov. Tshaj dhau ntawm cov khoom siv hluav taws xob hauv cov thawv hom hloov tau yooj yim tuaj yeem ua rau rwb thaiv kev puas tsuaj thiab xoob xoob xoob kom ntev. Sab hauv luv luv luv ntawm lub thawv-hom hloov chaw kuj tseem yuav ua kom kub thiab txawm tias ua rau hluav taws. Cov tshuab cua cua tshuab hluav taws xob tseem yog qhov kub nyhiab thaum lub sijhawm ua haujlwm, thiab cov cua kub txuas ntxiv tuaj yeem yooj yim ua rau lub tshuab hloov hluav taws xob. Txhawm rau saib xyuas qhov kub dhau ntawm lub thawv-hom hloov chaw, nws yog qhov yuav tsum tau ntxuav cov khoom seem hauv lub thawv-hom hloov pauv, xws li plua plav, thiab lwm yam. thiab xa tawm cov cim qhia kub siab rau lub sijhawm.
2. Kev hloov chaw rau ntawm lub thawv hloov pauv yog ua txhaum. Tsuas yog nws tus kheej tsis ua haujlwm, lub on-load hloov hauv lub thawv-hom tsis tshua muaj poob. Qhov tsis ua hauj lwm ntawm lub tes hloov pauv yog feem ntau vim yog cov laj thawj hauv qab no: Ua ntej, tus tes hloov tau siv ntev, thiab tus ncej hloov tau deformed, ua rau lub pob hloov mus ua haujlwm thiab poob; qhov thib ob tivthaiv tsis muaj zog txaus ua rau tus kais kais raug puas ntsoog thaum ua haujlwm hloov chaw; Qhov thib peb yog qhov ua tau zoo ntawm qhov hloov pauv tsis yog raws li tus qauv, thiab qhov ntxaiv tawg tom qab lub sijhawm siv. Txhawm rau kom muaj kev ua haujlwm ruaj khov ntawm lub thawv hloov pauv, hloov pauv on-load yuav tsum nruj me ntsis thaum lub sijhawm txheej txheem ntau lawm kom ntseeg tau tias qhov zoo ntawm hloov thiab txheej txheem teeb tsa.
3. Lub tshuab hluav taws xob hluav taws xob tsawg ntawm lub thawv hloov pauv tau nrawm tsis ua haujlwm. Muaj ob lub ntsiab tseem ceeb rau lub tripping ntawm qhov hluav taws xob tsawg ntawm kev hloov ntawm lub thawv hloov. Ib qho yog qhov tsis ua hauv npav; tus tod yog hloov malfunction. Thaum lub tshuab hluav taws xob tsawg hloov mus ua haujlwm tsis ua haujlwm, lub thawv hom kev hloov pauv yuav tsum tau ua tib zoo tshuaj xyuas. Thaum dhau kev tiv thaiv tam sim no tshwm sim nyob rau sab qis-hluav taws xob sab ntawm lub zog hloov hluav taws xob, cov khoom siv cuam tshuam yuav tsum tau kuaj xyuas thiab tiv thaiv tam sim ntawd. Nyob rau tib lub sijhawm, tshem tawm qhov tsis zoo ntawm tus tes hloov thiab tsom mus rau seb nws puas yog tsis ua haujlwm npav lossis tsis ua haujlwm txoj kab. Tshawb xyuas cov khoom txuas ntxiv, xyuas seb daim phaj tiv thaiv ntawm cov khoom siv puas raug tso tseg, thiab yog tias tsim nyog, coj cov khoom kuaj kev paub zoo.
Kev tshuaj xyuas thiab kho cov teeb meem txhaum nyob rau hauv lub thawv hloov chaw
1. Box-hom kev hloov ua haujlwm theem mus ncig ua si feem ntau muaj xws li hloov hluav taws xob hloov mus txuas thiab kab hloov mus txuas. Lub tshuab hloov hluav taws xob tseem ceeb tau faib ua peb sab sab kev ua txhaum ntawm qhov hloov hluav taws xob tseem ceeb thiab lub tshuab hluav taws xob tsawg sab hluav taws xob kom paub qhov tseeb ntawm lub ntsiab hluav taws xob. Kev txiav txim siab dab tsi ua rau kev hloov pauv mus ncig ntawm lub thawv-hom hloov pauv tsuas yog nyob ntawm ntau yam kev soj ntsuam cov ntaub ntawv.
2. Thaum lub npov sab nraud-hom kev hloov pauv tau muaj qhov tsis ua tiav, cov neeg ua haujlwm tu yuav tsum maj mus rau qhov tshwm sim sai li sai tau thiab rov ua lub zog sai li sai tau. Cov neeg ua haujlwm saib xyuas ua ntej tshawb xyuas seb cov cuab yeej puas raug puas ntsoog loj, thiab tom qab ntawd kuaj xyuas cov haujlwm ua haujlwm ntawm qhov hloov mus txawv tebchaws thiab cov xov hluav taws xob (arc) kev coil. Rau lub caij nplooj zeeg hloov hluav taws xob lub zog, xyuas seb lub caij nplooj ntoos hlav hluav taws xob cia tsis ua hauj lwm, thiab rau lub tshuab hluav taws xob, xyuas lub pob hluav taws xob hloov hluav taws xob.
3. Thaum lub sijhawm qis ntawm kev mus ncig ntawm lub ntsiab transformer ntawm lub thawv-hom transformer tsis ua tiav, tshawb xyuas cov kab tiv thaiv thiab tiv thaiv lub ntsiab hluav taws xob tseem ceeb hauv cov cuab yeej hloov mus nrhiav qhov ua kom muaj kev sib tsoo. Thaum overcurrent tiv thaiv nyob rau sab hluav taws xob tsawg ntawm qhov hloov pauv yog tib qho uas ua rau tsis ua hauj lwm, cov kab ua txhaum yuav raug tshem tawm, cov ntsiab lus tso tawm yuav tsum kuaj xyuas, thiab tom qab ntawd cov cuab yeej hloov mus yuav tsum kuaj xyuas. Thaum overcurrent tiv thaiv ntawm qhov tsawg voltage sab ntawm lub hloov hluav taws xob kuj muaj kab tiv thaiv, nws tuaj yeem ncaj qha raws li txoj kab txhaum raws li seb cov kab puas lawm. Cov neeg ua haujlwm saib xyuas yuav tsum tsis tsuas yog xyuas cov kab tawm ntawm txoj haujlwm, tabsis tseem tshawb xyuas tag nrho cov kab kom tshem tawm cov kab txhaum Tom qab ntawd, kev hloov mus ncig ua txhaum kev ua haujlwm tuaj yeem ua.
Qhov ceeb toom rau hluav taws kub thiab pov thawj tawg ua haujlwm ntawm lub thawv hloov chaw
1. Lub thawv tso rau hauv lub thawv tsis tuaj yeem thauj ntev dhau lawm, tshwj xeeb tshaj yog tom qab siv ob peb xyoos, koj yuav tsum pib them sai sai rau cov teeb meem xws li coil laus thiab rwb thaiv kev laus kom tiv thaiv luv luv hauv kev.
2. Yog hais tias lub tshuab roj-hloov lub tshuab hluav taws xob tau nruab rau hauv lub thawv hloov chaw, lub rwb thaiv kev ua tau zoo ntawm cov roj transformer yuav tsum raug kuaj xyuas tsis tu ncua, thiab cov tsis tsim nyog yuav tsum tau hloov lub sijhawm.
3. Thaum lub sijhawm ua haujlwm ntawm kev hloov chaw prefabricated, kev ua haujlwm ntawm kev hloov pauv yuav tsum tau soj ntsuam txhua lub sijhawm los tiv thaiv lub sijhawm kub ntev ntawm cov tub ntxhais hloov hluav taws xob thiab ua rau cov rwb thaiv kev laus, thiab kev saib xyuas yuav tsum tsis saib xyuas kom tsis txhob ua rau txheej txheej rwb thaiv tsev thaum lub sij hawm tu Cov.
4. Ua tib zoo saib xyuas cov teeb meem tiv thaiv xaim thaum lub sijhawm saib xyuas txhua hnub ntawm lub thawv hloov chaw, thiab cuam tshuam nrog cov xov hlau tsis zoo hauv lub sijhawm.
5. Lub tshuab hluav taws xob ntau hloov pauv, hloov pauv, thiab hluav taws xob qis ntawm lub thawv uas tau teeb tsa ua ntej yuav raug nruab nrog lub teeb hluav taws xob, lub hom phiaj yog tiv thaiv xob laim los ntawm kev puas tsuaj rau cov khoom siv thiab tiv thaiv kev nyab xeeb kev ua haujlwm ntawm lub thawv-hom cov duab mus los.
6. Hauv kev tsim theem ntawm lub thawv-hom hloov chaw, nws yog qhov yuav tsum xav txog kev ua pa thiab ua kom muaj cua sov, thiab tsim kom muaj qhov cua txaus thiab cov kiv cua kom zoo. Ziguang box-type substation yog nruab nrog cov pa hauv chav tso pa hauv chav hloov hluav taws xob thiab chav ntsuas hluav taws xob tsawg. Chav hloov pauv muaj ib qho kev tswj qhov kub thiab txias uas tuaj yeem tswj tau qhov zoo. Qhov kub hauv lub thawv hom hloov chaw.
