Yuav ua li cas lub voltage hloov ua haujlwm?
Ib qho hluav taws xob hloov (VT, lossis cov peev txheej muaj peev xwm txuas nrog cov khoom siv hluav taws xob, yog li cov khoom siv tiv thaiv kev nyab xeeb los yog tswj hwm cov hauv qab no yog cov lus piav qhia ntawm nws cov ua haujlwm Lub hauv paus ntsiab lus:
{{0 {}} Cov tub ntxhais ua haujlwm ua haujlwm: electromagnetic induction
1) Cov qauv theem pib
Thawj winding: ncaj qha txuas nrog cov kab hluav taws xob siab kom raug ntsuas (xws li 10kv, thiab lwm yam ntawm cov thib .
Thib ob winding: tawm cov khoom siv qis qis (xws li 100v), nrog tsawg dua tig, txuas nrog ntsuas lossis cov khoom tiv thaiv.
2) cov yam ntxwv ua haujlwm
Kev Ua Haujlwm Circuit Court kwv yees: Lub impedance ntawm lub cuab yeej lossis kev tiv thaiv ib sab yog qhov siab dua (Milliam Espormer yog ze rau tsis muaj-thauj lub xeev .
Cov Kev Xav Tau Siab: Qhov yuam kev yuav tsum tau tswj tsis pub dhau ± 0}} 2% (raws li qhov tseeb qib) kom ntseeg tau qhov tseeb ntawm kev ntsuas thiab cov cim tiv thaiv.
2. cov haujlwm tseem ceeb thiab cov yam ntxwv
1) Voltage rho tawm thiab kev nyab xeeb
Cov rwb thaiv tsev tsim cais cov kev sib txuas qib theem thawj thiab chav ntsuas hluav taws xob qis los tiv thaiv kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom siv kev nyab xeeb .
2) qib qhov tseeb
PT rau kev ntsuas: 0 . 2 qib (hluav taws xob hluav taws xob (0.5 qib (ntsuas ntsuas dav dav)
Pt rau kev tiv thaiv: qib 3p, qhov yuam kev loj tau raug tso cai tab sis cov lus teb sai sai rau kev ua txhaum cai thaum lub sijhawm luv luv).
3) LOUNT
Lub nra hnyav dua yuav tsum yog lub peev xwm nyob hauv lub peev xwm (xws li 30va) . overload angreed lossis txawm tias puas .
3.} Khomob Kev Pabcuam
1.} voltage ntsuas
Txuas voltmeters, fais fab metres, zog me me, thiab lwm yam .
2.} relay tiv thaiv
Muab cov cim ntsuas rau overvoltage / undervoltage tiv thaiv, kev tiv thaiv deb thiab lwm cov khoom .
3.}} synchronous tswj
Muab theem thiab cov hluav taws xob amplitude siv thaum txuas nrog daim phiaj rau lub hwj chim tiam .
4. Txawv ntawm voltage volter thiab tam sim no hloov
Cov yam ntxwv hluav taws xob volter (PT) voltage transformer (PT)
Lub xeev ua haujlwm kwv yees li tsis muaj-thauj (siab impedance load) kwv yees li tsis muaj-thauj (siab impedance load)
Theem nrab sab yuav tsum tsis muaj kev sib tw sib tw (yuav hlawv) Tsis qhib Circuit Court (tsim kev phom sij siab (ua kom muaj hluav taws xob txaus ntshai)
Tso zis teeb liab voltage (xws li 100v) tam sim no (xws li 5A lossis 1a)
Piv Txwv 1000: 1 rau siab dua feem ntau yog cov piv txwv (xws li 1000: 5)
5.} Kev faib tawm ntawm voltage hloov pauv tuaj yeem faib ua cov hauv qab no 3 pawg raws li cov insulating nruab nrab
1) Qhuav Voltage Transformer
Cov Khoom Siv Insulating: Epoxy Resin lossis Casting Khoom .
Nta:
Txij Nkawm-Dawb, tsis muaj kev pheej hmoo ntawm cov roj towage, haum rau sab hauv tsev qhuav .
2) Cov roj-siv voltage transformer
Rwb thaiv tsev cov khoom siv: transformer roj .
Nta:
Kev tswj kom muaj zog rwb thaiv tsev ua haujlwm, kom sov sov dissipation, tsim nyog rau sab nraum zoov lossis siab vaum ib puag ncig .
3) Roj Accessulated Voltage Transformer (GIS PT)
Rwb thaiv tsev cov khoom: SF6 roj av .
Nta:
Muaj kev sib xyaw ua ke, qhov loj me, siv rau cov roj insulated hloov txee (GIS) {{0}.
Haum rau cov chaw sib xyaw xws li cov neeg hauv nroog loj .
6.} Kev ceev faj
1) Cov ntaub ntawv pov thawj tsis tu ncua: xyuas kom meej tias qhov piv thiab theem yuam kev raws cov qauv (xws li ib xyoos ib zaug).
2) Rwb thaiv tsev cov laus tshawb tau: cov rwb thaiv tsev kev ua haujlwm ntawm cov tub ntxhais thiab cua yuav tsum tau kuaj xyuas tom qab lub sijhawm ua haujlwm ntev.
Los ntawm cov hluav taws xob voltage, lub zog hluav taws xob tau pom zoo saib xyuas thiab kev tswj hwm ntawm lub qhov muag muaj zog "rau kev ua haujlwm ruaj khov ntawm lub zog ntawm lub hwj chim sib tshooj.
JDZX 9-35 voltage transformercan be used to measure, monitor and relay the voltage of incoming and outgoing lines. It can accurately convert 35kV high voltage into low voltage, provide reliable voltage signals for various measuring instruments, protection devices and control systems in the substation, and ensure the safe and stable operation of the substation.
JDZX 9-35 voltage transformer muaj ntau cov lus tawm tswv yim:
Zoo rwb thaiv tsev kev ua tau zoo
Lub Epoxy Resin tag nrho Casting qauv yog tus coj mus thaiv cov khoom siv sab nraud, thiab kev tawm tsam thiab tiv thaiv kev ua kom muaj peev xwm ua kom muaj peev xwm ua tau zoo complex kev ua haujlwm ib puag ncig, thiab tseem tuaj yeem tswj tau ruaj khov nyob rau hauv harsh huab cua thiab pureded ib puag ncig thiab pureded ib puag ncig.
Siab Precision
Rau cov haujlwm xws li hluav taws xob metering, voltage xyuas thiab kev xaiv cov cuab yeej siv hluav taws xob, uas muaj peev xwm txhim kho cov ntaub ntawv tseem ceeb thiab cov khoom siv txhim khu kev tsim nyog, cov khoom siv txhim khu kev siv hluav taws xob, kev tswj hwm thiab kev tiv thaiv ntawm lub zog System .
Compact qauv
Qhov loj me thiab qhov hnyav: txheej txheem txheej txheem sib xyaw thiab muaj qhov chaw tso tseg thiab cov chaw muab kev thauj khoom siv thiab kev teeb tsa kev tsim kho thiab cov nqi zog,.
