Kev ceev faj rau prefabricated substations feem ntau suav nrog kev teeb tsa, kev ua haujlwm, kev saib xyuas, thiab kev tiv thaiv kev nyab xeeb, thiab tseem ceeb heev rau kev ua kom ntev ntev - lub zog ruaj khov thiab kev nyab xeeb ntawm cov neeg ua haujlwm.
Kev xaiv qhov chaw thiab teeb tsa kev ceev faj
Terrain thiab Drainage
Lub substation prefabricated yuav tsum tau muab tso rau hauv qhov siab -dej thaj chaw uas tsis muaj dej sib xyaw kom tsis txhob muaj dej nag ntws rov qab rau hauv lub thawv thiab cuam tshuam rau kev ua haujlwm ntawm cov khoom siv hluav taws xob.
Foundation thiab Levelness
Lub hauv paus pob zeb yuav tsum ruaj khov thiab theem, nrog rau kab rov tav yuam kev tsis pub tshaj 5 hli, thiab cov kev cai yuav tsum tau ua rau cable nkag / tawm raws thiab grounding electrode installation qhov chaw.
Qhov cua thiab cua sov Dissipation
Qhov chaw teeb tsa yuav tsum xyuas kom muaj qhov cua zoo. Lub qhov rooj chav tsev transformer yuav tsum tsis txhob raug thaiv kom yooj yim rau huab cua ncig thiab cua sov dissipation. Nws yog nruj me ntsis txwv tsis pub ua cov khib nyiab nyob ib puag ncig ntawm lub qhov rooj, vim qhov no yuav cuam tshuam rau kev saib xyuas thiab cua kub dissipation.
Txhim khu kev ntseeg hauv av
Tus neeg xyuas pib hauv av yuav tsum yog tus neeg xyuas pib tooj liab nrog tus ntoo khaub lig- thaj tsam ntawm tsis pub tsawg dua 30mm². Daim phiaj hauv av yuav tsum tau muab faus tsawg kawg yog 1 meter hauv av, thiab ntau txoj kab ntsug hauv av yuav tsum tau muab ntsia kom txo qis hauv av, kom tsis txhob muaj ntau tshaj 4Ω.
Tsis txhob vibration thiab Electromagnetic cuam tshuam
Nws yuav tsum tsis txhob muab ntsia rau hauv cov cheeb tsam uas muaj zog vibration, cuam tshuam, los yog muaj zog electromagnetic induction los tiv thaiv kev puas tsuaj rau cov khoom sab hauv.
Kev Tswj Xyuas Kev Nyab Xeeb Thaum Ua Haujlwm
Txwv tsis pub ua haujlwm tsis raug cai
Txwv tsis pub qhib qhov siab - voltage chav tsev qhov rooj yog txwv nruj heev. Cov cuab yeej rwb thaiv tsev yuav tsum tau siv thaum lub sijhawm ua haujlwm, kev sib tsoo tshuab yuav tsum tau muab tshem tawm kom zoo, thiab kev ua haujlwm nyob tau nruj heev.
Tsis tu ncua Load Checks
Ua ib qho kev tshuaj ntsuam xyuas yam tsawg kawg ib hlis, xyuas peb -theem load tshuav nyiaj li cas, overload, ib txwm ntsuas ntsuas, thiab hloov txoj haujlwm raug.
Kev tiv thaiv hluav taws thiab tawg hauv qhov chaw
Cov khoom tawg yooj yim thiab tawg yuav tsum tsis txhob khaws cia nyob ib ncig ntawm lub qhov rooj. Cov tshuaj tua hluav taws uas tsim nyog (xws li cov hmoov qhuav lossis cov pa roj carbon dioxide extinguishers) yuav tsum tau muab, thiab lawv cov kev ua haujlwm siab yuav tsum tau kuaj xyuas tsis tu ncua.
Tiv thaiv me tsiaj nkag
Txhua lub qhov hluav taws xob thiab qhov hluav taws xob yuav tsum raug kaw kom nruj kom tsis txhob muaj cov tsiaj me xws li nas thiab nab los ntawm kev nkag mus thiab ua rau luv luv.
Cov Ntsiab Lus Saib Xyuas thiab Kev Kho Mob
Kev tshem tawm plua plav tsis tu ncua
Ua kom tshem tawm cov plua plav kom zoo tsawg kawg ib xyoos ib zaug. High-voltage thiab low-voltage chav tuaj yeem raug so nrog cov ntaub ntub dej. Rau chav transformer, nws raug nquahu kom siv lub tshuab nqus tsev lossis lub tshuab nqus tsev kom tshem tawm cov plua plav.
Tighten kev sib txuas
Vim thermal expansion thiab contraction, terminals yuav loosen. Tag nrho cov hlua hluav taws xob yuav tsum tau nruj txhua xyoo tom qab lub hwj chim raug txiav tawm kom tsis txhob muaj kev tiv thaiv ntau dhau, uas tuaj yeem ua rau muaj cua sov lossis hluav taws kub.
Rwb thaiv tsev Performance Test
Ua ib qho kev ntsuas kev tiv thaiv hluav taws xob txhua xyoo. Lub rwb thaiv tsev tsis kam ntawm 10kV system transformer windings yuav tsum tsis txhob qis dua 10MΩ. Kev ntsuas AC tiv taus hluav taws xob (xws li 30kV / 1min) tuaj yeem ua tau yog tias tsim nyog.
Kub thiab Humidity Control
Configure ib tug kub thiab humidity controller. Lub tshuab cua sov yuav tsum tau qhib thaum lub ambient humidity siab dhau los tiv thaiv condensation. Cov kiv cua yuav tsum tau kho tam sim yog tias lawv ua haujlwm tsis zoo.
Spare Circuit Court tuav
Tsis siv siab -voltage spare circuits yuav tsum raug kaw ua ntej energizing, los yog cov sockets yuav tsum tau muab kaw nrog tshwj xeeb insulating caps. Cov kaus mom plua plav yuav tsum tsis txhob siv rau qhov chaw insulating caps.
