Kuv yuav ua li cas yog tias dej nkag mus rau hauv lub thawv xa khoom? Puas muaj kev daws teeb meem zoo?

1. Txheeb xyuas tus contactor

Tus contactor yuav tsum tau kuaj xyuas cov kab hluav taws xob ua ntej, cov txheej txheem yog tib yam li lub tshuab hluav taws xob. Tom qab ntawd nws tseem yuav tsum tau qhib lub hau rau kev tshuaj xyuas. Loosen pem hauv ntej cover fastening screws, qhib nws, thiab tsom mus rau kev tshuaj xyuas cov neeg thiab arc extinguishing cover. Txoj kev tshuaj xyuas kev tiv tauj yog tib yam li lub Circuit Court breaker. Tshawb xyuas cov cim dej thiab ntxuav nws. Yog tias tsim nyog, txhuam nws nrog daim ntawv gauze zoo, tab sis ceev faj kom tsis txhob txhuam nws. Qhov sib txawv ntawm lub arc extinguishing npog yog qhov nqaim, tshuab kom zoo zoo, thiab tsis txhob tso dej tawm.

Tom qab ntawd lub contactor coil yuav tsum tau kuaj xyuas. Saib seb puas muaj dej tsuj hauv lub kauj. Tom qab ziab rau ib hnub, xyuas qhov DC tsis kam ntawm lub kauj. Feem ntau, DC tsis kam ntawm lub kauj yuav raug cim rau ntawm lub kauj. Muab piv nrog tus nqi ntawm multimeter. Yog tias qhov sib txawv tshaj 20%, nws yog qhov yooj yim siv tsis tau thiab yuav tsum tau hloov. Cov neeg pabcuam pabcuam ntawm tus contactor thiab cov neeg pabcuam sab nraud yuav tsum tau kuaj xyuas. Lawv kuj tau disassembled, cov dej ntim tau raug ntxuav, thiab cov neeg raug kuaj xyuas.

Tom qab tag nrho cov kev soj ntsuam tiav lawm, lub contactor cover yog pib dua thiab lub rwb thaiv tsev yog ntsuas nrog ib tug rwb thaiv tsev tester. Cov kev xav tau yog tib yam li cov ntawm cov Circuit Court breaker. Tom qab ntawd txuas cov khoom siv hluav taws xob ib ntus, ua kom lub zog kaw lub kauj, xyuas qhov kev ua haujlwm ntawm tus contactor, thiab siv lub tshuab multimeter los xyuas seb lub ntsiab lus tseem ceeb thiab qhov chaw pabcuam puas nyob zoo.

2. Tshawb xyuas lub Circuit Court breaker

Lub nra ntawm lub thawv xa khoom yog lub twj tso kua mis hluav taws thiab lub twj tso kua dej. Cov circuits no tsawg kawg yuav muaj Circuit Court breakers thiab contactors. Cia peb tham txog Circuit Court breaker ua ntej.

Rau cov hluav taws xob hluav taws xob uas tau muab tso rau hauv dej, ua ntej kos lub terminals sab sauv thiab sab qis, loosen lub phaj tooj liab lossis cable thiab cable qhov ntswg, ntxuav cov dej sib xyaw, ntxuav qhov chaw sib cuag, thiab txhuam nws yog tias muaj xeb. Tom qab ntawd qhib lub hau los xyuas. Yog hais tias lub Circuit Court breaker muaj ib tug ntxiv kev khiav hauj lwm mechanism, tshem tawm cov kev khiav hauj lwm mechanism ua ntej. Tom qab ntawd tshem cov ntsia hlau kho ntawm lub Circuit Court breaker, feem ntau yog plaub mus rau tsib, thiab unscrew lawv ntawm pem hauv ntej ntawm lub Circuit Court breaker. Tshem lub plhaub pem hauv ntej thiab saib seb puas muaj dej nyob hauv lub tshuab hluav taws xob. Yog tias muaj, so kom huv si, qhuav nws, lossis tshuab kom qhuav. Xyuas seb qhov kev txav thiab zoo li qub ntawm cov hluav taws xob hluav taws xob puas yog qhov txawv txav, seb puas muaj oxidation thiab stains tom qab dej raus dej, yog tias muaj, txhuam lawv nrog 500-grit zoo sandpaper. Nco ntsoov tsis txhob over-polish kom tsis txhob cuam tshuam rau kev sib cuag thiab kev sib cuag.

Tom ntej no, yog hais tias muaj tripping coils thiab auxiliary contacts nyob rau hauv lub Circuit Court breaker, lawv yuav tsum tau soj ntsuam nyias. Lub tripping coil tuaj yeem raug kuaj xyuas ncaj qha nrog lub multimeter los txiav txim seb puas muaj cov hlau tawg; saib seb puas muaj dej tsub zuj zuj hauv lub kauj. Yog tias muaj, nws raug nquahu kom hloov nws; Raws li qhov ntsuas hluav taws xob ntawm lub kauj, xaiv lub zog ib ntus los sim seb lub kauj tuaj yeem ua haujlwm li cas. Rau cov neeg sib cuag, ua ntej xyuas seb puas muaj dej tsub zuj zuj. Tom qab ntxuav, koj tuaj yeem siv lub cuab yeej los nias qhov kev sib cuag mechanism thiab siv lub tshuab ntsuas ntau los xyuas seb qhov kev sib cuag yog nyob rau thiab tawm li cas. Yog tsis yog, hloov nws.

Yog hais tias lub Circuit Court breaker yog nruab nrog kev tiv thaiv to, xyuas cov leakage tiv thaiv Circuit Court thiab coil tib yam li tripping coil. Tom qab ua tiav cov kev txheeb xyuas saum toj no, rov pib dua lub Circuit Court breaker, manually qhib thiab kaw lub Circuit Court breaker ob peb zaug, thiab siv multimeter los xyuas qhov qhib thiab tawm ntawm txhua theem ntawm Circuit Court breaker. Siv lub ntsuas hluav taws xob los ntsuas qhov rwb thaiv tsev tiv thaiv ntawm txhua theem ntawm Circuit Court breaker thiab txhua theem rau hauv av. Raws li qhov tshwj xeeb, nws yog ntau dua 0.5 megohms kom tau raws li qhov yuav tsum tau ua, tab sis hauv kev ua haujlwm tiag tiag, nws raug pom zoo kom ntau dua 2 megohms.

3. Tshawb xyuas PLC thiab inverter

Ob yam no tuaj yeem nyob hauv lub thawv xa khoom. Yog tias lawv tau tsau rau hauv dej, nws tsis yooj yim los tshuab ziab dej yog tias lub hau tsis qhib rau kev tu kom huv. Kev tshuaj xyuas yog qhov nyuaj. Nws raug nquahu kom tshem tawm lawv thiab xa mus rau cov kws tshaj lij txhawm rau tshuaj xyuas kom ntxaws. Txheeb xyuas cov haujlwm ntawm inverter thiab PLC yam khoom los ntawm cov khoom, thiab kho lossis hloov lawv. Lub PLC eeds yuav tsum tau re-programmed, thiab lub inverter yuav tsum tau re-parameterized.4. Kos lub cable 5. Tshawb xyuas lub voj voog thib ob

Qhov thib ob Circuit Court tej zaum yuav muaj cov nyees khawm, qhov taw qhia teeb, fuses, tam sim no thiab voltage meters, lub zog transformers, tam sim no transformers, thiab lwm yam. Xyuas lawv ib tug los ntawm ib tug. Disassemble thiab xyuas cov uas tuaj yeem disassembled. Qhuav kom huv si cov uas tsis tuaj yeem disassembled. Tom qab kev tshuaj ntsuam xyuas, xyuas cov rwb thaiv tsev ntawm lub voj voog thib ob, tsis pub tsawg dua 0.5 megohms.

Cov ntsiab lus saum toj no yog qhov koj yuav tsum tau them sai sai rau tom qab lub thawv xa khoom raug dej nyab. Kuv vam tias nws yuav pab tau rau sawv daws. Tau kawg, koj tuaj yeem them nyiaj rau SDKC kom paub ntau ntxiv txog cov thawv xa khoom.https://www.kaichuanpower.com/
