Kev ntsuas hluav taws xob siab ntawm cov npav npav yog ib kauj ruam tseem ceeb los xyuas kom meej nws txoj kev nyab xeeb thiab kev ntseeg siab hauv cov tshuab hluav taws xob. Qhov no suav nrog kev siv hluav taws xob siab rau cov tsheb npav los xyuas qhov kev ruaj ntseg ntawm cov rwb thaiv tsev, qhov muaj peev xwm tsis muaj zog, lossis qhov tsis xws luag uas tuaj yeem ua rau hluav taws xob tsis ua haujlwm lossis muaj kev phom sij.
Tib qhov kev ntsuas uas yuav tsum tau muab xam rau hauv lub busbar high voltage test yog qhov xau tam sim no nrog IR test kom ntseeg tau tias cov rwb thaiv tsev ua haujlwm zoo. Thaum lub tsheb npav CB qhib, cov dej xau tam sim no yuav yog ib nrab piv rau cov tsheb npav CB kaw.
* Kev npaj yuav tsum tau ua ua ntej ua HV xeem
Tag nrho cov CT thib ob circuits yuav tsum luv luv, cais, thiab earthed kom zoo
Tag nrho VT lub voj voog thib ob yuav tsum qhib thiab tag nrho VT racked tawm
BUS BAR rau kev sim yuav tsum huv thiab tsis muaj plua plav thiab roj
Txhua qhov kev hloov hauv av ntawm BUS BARS yuav tsum nyob hauv lawv txoj haujlwm qhib
Tag nrho cov kev hloov hauv av ntawm lub voj voog yuav tsum nyob hauv lawv txoj haujlwm qhib
MV cables yuav tsum raug txiav tawm ntawm SWGR, thiab cov kab txuas txuas yuav tsum tau muab tso rau hauv av & raug cais tawm ntawm ib leeg.
Tag nrho cov haujlwm ua haujlwm hauv chav SWGR yuav tsum raug cuam tshuam thiab cov neeg ua haujlwm yuav tsum raug ceeb toom txog qhov ntsuas hluav taws xob siab.
* Kev npaj ua ntej thov HV xeem
Case 1.
Rwb thaiv tsev Resistance xeem Ua ntej & Tom qab HV Test thaum CB racked hauv & qhib
High Voltage Test thaum CB racked hauv & qhib
Case 2.
Rwb thaiv tsev Resistance xeem Ua ntej & Tom qab HV Test thaum CB racked nyob rau hauv kaw
High Voltage Test thaum CB racked hauv & kaw
Case 3.
High Voltage Test rau VT thaum CB racked hauv & kaw
Case 4. Kev ntsuas ntsuas rau VT thaum CB racked hauv & kaw
* Rwb thaiv tsev Resistance xeem Ua ntej & Tom qab HV xeem
Hauv peb qhov xwm txheej, cov xwm txheej ua ntej rau IR yuav zoo ib yam
1. CB racked hauv & qhib.
2. VT racked out.
3. Tag nrho cov kev tiv tauj Cable yog luv luv thiab hauv av.
4. Txhaj los ntawm lub vaj huam sib luag yuav tsum tau ua.
5. Siv 5 kV DC rau 1 feeb ntawm ib theem thaum grounding ob theem.
Nco tseg:
Nyob rau hauv cov ntaub ntawv ntawm HV xeem CB / VT raws li txoj cai & Txhaj voltage magnitude yuav txawv raws li cov ntaub ntawv.
Xyuas kom tseeb tias tsis muaj lub suab txawv txav thaum txhaj tshuaj hauv ib lub vaj huam sib luag hauv lub npav tag nrho
* High Voltage Test ntawm 13.8kV SWGR
Cov xwm txheej ua ntej
1. Tag nrho cov kev sib cuag Cable yog luv thiab hauv av.
2. Txhaj tshuaj los ntawm lub vaj huam sib luag xav tau.
3. Txhaj hluav taws xob rau 1 feeb ntawm ib theem thaum grounding lwm ob theem.
4. Kuaj txhua kis rau R- Y-B theem raws li
Case 1
CB racked IN & Qhib
VT racked OUT
Txhaj 3 zaug rau qhov ntsuas Voltage
Case 2
CB racked IN & Kaw
VT racked OUT
Txhaj 3 zaug rau qhov ntsuas Voltage
Case 3.
CB racked IN & Kaw
VT racked IN
Txhaj 1.5 npaug rau Nominal Voltage
Case 4.
CB racked IN & Kaw
VT racked IN
Txhaj Nominal Voltage & ntsuas ntsuas & xyuas kom tag nrho VT circuits ua haujlwm zoo kawg nkaus.
Wuhan Huayi hluav taws xob fais fab yog lub chaw tsim khoom ntawm cov khoom siv kuaj thiab tseem muab cov kev daws teeb meem rau GIS / cable / transformer thiab lwm yam haujlwm. Tsim los ntawm xyoo 2005, nyob hauv Wuhan, Suav.
