Dab tsi yog Txoj Kev Txhim Kho Rau Tsawg-voltage Distribution Txee?

Kev saib xyuas ntawm cov khoom siv hluav taws xob qis hluav taws xob feem ntau yog los xyuas kom muaj kev ua haujlwm zoo thiab muaj kev nyab xeeb ntawm cov khoom siv hluav taws xob tsawg hluav taws xob. Lub tshuab hluav taws xob qis hluav taws xob yuav tsum tau kuaj xyuas thiab khaws cia txhua xyoo. Kev saib xyuas yog ua tiav nrog lub sijhawm hluav taws xob tsawg kawg nkaus, thiab tus tswv lub sijhawm hluav taws xob feem ntau txiav txim siab ua ntej.

Cov ntsiab lus thiab cov kauj ruam ntawm kev saib xyuas cov khoom siv hluav taws xob tsawg-voltage:

1. Kev saib xyuas yuav tsum pib los ntawm qhov qis-voltage sab ntawm lub transformer. Tom qab lub tshuab hluav taws xob faib hluav taws xob tau muab tshem tawm, ntxuav cov plua plav hauv lub txee, xyuas seb lub busbar thiab down-conductor puas muaj kev sib txuas zoo, seb cov pob qij txha puas yog cua sov thiab tsis muaj xim, xyuas seb lub taub hau cable thiab cov kab hluav taws xob puas ruaj khov thiab txhim khu kev qha. , xyuas seb cov xaim hauv av puas yog corroded, thiab seb cov kab hluav taws xob lub taub hau puas yog xeb. Puas yog nruj. Tag nrho cov kev sib txuas ntawm cov kab hluav taws xob thib ob yog txhim khu kev qha, thiab cov rwb thaiv tsev ua tau raws li qhov yuav tsum tau ua.

2. Thaum kuaj xyuas lub tub rau khoom hloov, lub txee hloov lub txee yuav tsum tau hloov pauv thaum raug thawb los yog rub tawm, thiab cov cuab yeej ntsuas phoo yog txhim khu kev qha. Xyuas seb lub tshuab hluav taws xob tsis siv neeg hloov pauv kev ua haujlwm ntawm lub tub rau khoom puas nyob hauv qhov chaw thiab seb cov hlua txuas puas raug kaw. Tshem tawm cov av ntawm qhov chaw sib cuag thiab ib puag ncig ntawm tus contactor, thiab xyuas seb qhov kev sib cuag ntawm tus contactor puas zoo. 1/3 ntawm thickness), cov neeg sib cuag yuav tsum tau hloov. Qhov taw qhia lub zog thiab qhov taw qhia teeb nyob rau hauv qhov zoo.

3. Thaum overhauling lub capacitor txee, lub ntsiab hloov ntawm lub capacitor txee yuav tsum tau disconnected ua ntej, thiab cov capacitors yuav tsum tau tawm mus rau hauv av ib tug los ntawm ib tug nrog ib tug hlau ntawm ntau tshaj 10mm2. Deal nrog nws nyob rau hauv lub sij hawm thiab hloov lub discharge ntaus ntawv, lub wiring screws ntawm lub tswj Circuit Court thiab lub grounding ntaus ntawv. Tom qab kaw, debug qhov qhia ib feem thiab qhov tsis siv neeg them nyiaj.

4. Overhaul ntawm Circuit Court breakers nyob rau hauv lub hwj chim txais txee thiab liaison txee: Tom qab disconnecting tag nrho cov loads, siv tus kov los co tawm lub Circuit Court breaker. Rov ua kom nruj lub davhlau ya nyob twg screws thiab xyuas seb lub elasticity ntawm cov hniav ua tau raws li qhov yuav tsum tau ua. Tshawb xyuas seb lub arc chute puas tawg lossis puas, xyuas seb qhov qhib thiab kaw ntawm lub tshuab cuam tshuam puas yog, xyuas seb cov neeg sib cuag puas zoo, kho thiab ua cov ntaub ntawv saum npoo ntawm cov neeg sib cuag yog tias tsim nyog, thiab xyuas seb puas muaj cov kab mob sab hauv, gaskets, thiab screws yog xoob, deformed thiab poob tawm. .

Overhaul ntawm lub substation:

1. Ua ntej ua haujlwm, yuav tsum tau ua raws li cov kauj ruam nram qab no: disconnect lub load ntawm qhov tsawg-voltage sab ib los ntawm ib tug, disconnect lub Circuit Court breaker nyob rau hauv high-voltage sab, tig rau hauv av hloov, xauv lub high-voltage switchgear, thiab dai ib "txhais kaw" ntawm tus kov ntawm lub switchgear. , ib tus neeg ua haujlwm " kos npe, thiab tom qab ntawd siv cov xaim ntawm 10mm2 lossis ntau dua kom luv lub busbar thiab dai hauv av xaim, thiab ceev cov busbar screws.

2. Cov kauj ruam ntawm kev ua haujlwm: rov ntxuav cov kev sib cuag ntawm cov busbars, siv lub hwj chim sib xyaw roj, khi lawv nrog lub caij nplooj ntoos hlav ntxhua khaub ncaws tshiab, xyuas seb cov insulators ntawm cov busbars thiab qhov chaw sib txuas yog txawv txav, xyuas qhov tam sim no, voltage, thiab lwm yam. Kev ntseeg tau ntawm kev sib txuas ntawm qhov thib ob winding terminals ntawm transformer.

3. Kev tshuaj xyuas thiab kuaj ua ntej xa hluav taws xob: tshem tawm tag nrho cov xaim hauv av thiab cov xaim luv luv, xyuas seb puas muaj cov cuab yeej tawm ntawm qhov chaw ua haujlwm, thiab tom qab lees paub tias lawv muaj tseeb, kaw qhov kev sib cais, tshem tawm qhov hloov hauv av ntawm qhov siab. -voltage sab, kaw lub Circuit Court breaker ntawm high-voltage sab ntawm kev khiav hauj lwm transformer, thiab coj lub tso rau hauv lub kos npe rau, xa lub hwj chim mus rau lub transformer, ces kaw lub Circuit Court breaker ntawm lub low-voltage sab fais fab mov txais txee, xa lub hwj chim. mus rau lub busbar, thiab thaum kawg kaw lub rooj sib tham uas cuam tshuam thiab qhov hloov pauv huab cua tsis siv neeg ntawm txhua ceg.

Cov kev ceev faj:

1. Thaum lub sijhawm tu, tus neeg tshwj xeeb yuav tsum tau teeb tsa los saib xyuas.

2. Hluav taws xob yuav tsum tau kuaj ua ntej ua haujlwm.

3. Cov neeg ua haujlwm saib xyuas yuav tsum paub txog thiab ua haujlwm ntawm cov khoom siv hluav taws xob thiab cov khoom sib txuas ntawm tag nrho cov khoom siv hluav taws xob.

4. Thaum lub sijhawm tu, koj yuav tsum paub meej tias cov kab twg yog ob-xaim fais fab mov.

5. Thaum overhauling lub busbar, cov seem seem nyob rau hauv kab yuav tsum tau tag nrho tawm.
