01 dav dav

1.1 phiaj xwm kev qhia

Ib tus neeg Asmeskas cov neeg Asmeskas tau hais tseg ib qho 20MVA-33 / 6.65kv kauj ruam hluav taws xob hloov pauv, cov neeg tuaj yeem hloov pauv, cov hluav taws xob tsawg dua rau hauv zos thiab thoob ntiaj teb. Qhov hloov pauv no tseem yog ib qho ntawm cov hloov pauv loj rau kev hloov chaw. South Africa yog ib lub teb chaws tseem ceeb tshaj plaws nyob hauv lub ntiaj teb, thiab muaj ib qho kev thov loj rau cov roj av rau cov mines.

Cov kauj ruam nqes hluav taws xob transformer adved iec 60076- 1: 2011 txheem. Nws tau txais cov txheej txheem ntawm onan txias. Cov pab pawg hluav taws xob: Ynyn0, haum rau ib puag ncig ua av. Cov khoom winding yog tooj liab, thiab tus tooj liab ploj yog qis dua. Nws tau ntsuas ntawm 33KV ntawm thawj sab thiab 6.65kv ntawm sab ob. Nruab nrog ib qho ntawm {{14} lead tap Changer (OLTC) nrog hloov hluav taws xob ntau hauv kev thauj khoom, kom muaj zog ruaj khov rau cov khoom siv sib xyaw. Lub transformer ua tiav zoo lub zog ua tau zoo, nrog tsis muaj lub zog ua haujlwm, nrog tsis muaj {{} Taug kev poob ntawm 75 qib ntawm 132.8 kW, thiab tag nrho cov poob. Txhawm rau txhim kho kev mus cuag tau, tshwj xeeb tshaj yog nyob rau thaj chaw deb chaw, tus transformer yog tsim nrog hnyav {21} Txhob xaim hluav taws xob, ua kom yooj yim dua rau ntawm kev ua haujlwm.

Vim li cas nws zoo tagnrho rau kev siv mining cov ntawv thov

Nyob rau hauv cov haujlwm sib khuav, ib qho kev ntseeg tau zoo thiab muaj txiaj ntsig zoo yog qhov tseem ceeb kom ntseeg tau tias kev nyab xeeb thiab khoom tsim nyog. Qhov hloov pauv no zoo kawg nkaus haum rau cov mining mining fais fab hluav taws xob cuam tshuam cov xwm txheej:

Cov hloov chaw: Cov kauj ruam hauv 33KV los ntawm cov chaw sib pab hluav taws xob lossis chaw nres tsheb raug txhom rau 6.6kv, tus qauv hluav taws xob rau cov cuab yeej siv mining.

Kev xa khoom hluav taws xob: transmits 6.6kV lub zog los ntawm cables mus rau undergtrial undergtrage rau ntev kev kis nrog qis poob.

Siab - Cov Khoom Siv Hluav Taws Xob Loj: Powers Qhov Tseem Ceeb Tseem Ceeb {} Diaby, Cov Khaub Ncaws Hnav, thiab Cov Twj Dewaterater.

2.3 Tank

Lub 20 MVA fais fab roj tank tank yuav tsum tau hla lub siab sim ua ntej tawm hauv lub hoobkas. Txhua cov pob qij txha, Flange pob qij txha, thiab bushing bases yog tsim los kom muaj ntev} Lub sij hawm sealing kev ntseeg tau. Clumpotable phaj - hom radiators yog saws, thiab plaub 10 {tuj lub log yog ntsia hauv qab kom yooj yim rau kev txav chaw. Lub manhole tau muab rau ntawm sab ntawm lub tank los pab txhawb kev tshuaj xyuas sab hauv thiab txij nkawm ntawm cov khoom siv.

2.4 Lub Rooj Sib Tham Zaum Kawg

1. Qhov kev nquag ntawm cov transformer hauv daim duab tau sib dhos, thiab tus tester yog kev sim ua haujlwm hluav taws xob.

2. Qhov nquag nquag tau raug tsa mus rau hauv lub tank.

3. Nruab lwm qhov chaw: Cov Roj Ntsuas Kub, Qhov Ntsuas Hluav Taws Xob Kub, Ua Phem Rau Cov Hluav Taws Xob, Pob Txha, Lub Caij Npav, Cov Log (10T).

4. Ncuav insulating roj rau hauv lub tank transformer los sau cov chaw sab hauv ntawm tus hloov pauv thiab xyuas kom meej tias cov roj theem raws li cov cai.

5. Vim yog thaj chaw loj nyob los ntawm lub radiator, nws yuav sib sau ua ntej xeem thiab tom qab ntawd disassembled thiab ntim rau kev thauj mus los tom qab sim.

Qhov no 20mva - 33 / 6.65Kv kauj ruam {{}}} down down fais fab hloov pauv yog ua rau kev ua haujlwm me. Nws yog qhov muaj zog, muaj txiaj ntsig, thiab yooj yim txav. Nrog IEC 60076-1: 2011 Ua raws li cov paj ntaub zoo, thiab cov kev cai OL ADVTC kev cai. Nws muab ruaj khov thiab yoog raws lub zog rau kev txiav. Lub tank yog qhov muaj zog, cov radiators tuaj yeem tshem tawm, thiab lub log muaj zog heev. Qhov no ua rau nws yooj yim siv rau ntawm cov chaw deb.

Nws tau qis kev poob, siab ua haujlwm, thiab yog yooj yim los tuav. Qhov no qhia tau peb lub hom phiaj kom muab cov khoom siv cov neeg siv khoom siv uas ua tau raws cov qauv thiab ua raws li kev nyab xeeb thiab ua haujlwm. Kev tsuas hauv South Africa yog loj hlob sai. Peb txaus siab txhawb nqa peb cov neeg koom tes nrog cov kev daws teeb meem hluav taws xob uas ua kom cov haujlwm tau khiav zoo niaj hnub no thiab rau yav tom ntej.
