Dab tsi yogHipot xeem voltage?
Hipot (high -} tej zaum) kev ntsuas voltage sivTshaj - kev ntsuas siab hluav taws xob(Siab dua cov qib kev ua haujlwm) rau cov khoom siv hluav taws xob kom paub tseebRwb thaiv tsev kev koom siabCov. Nws yog "Litmus sim" rau Dielectric lub zog- Simulating tsis zoo- teeb meem xwm txheej ua ntej kev puas tsuaj tshwm sim.
Hom HIPOT kev sim
AC hipot
Siv lwm qhov hluav taws xob tshiab.
Qhov zoo tagnrho rau kev kuaj xyuascreepage lossis paug yuam kev(Piv txwv li, hauv transformers).
DC hipot
Siv ncaj qha rau hluav taws xob tam sim no.
Zoo dua rau kev kuaj xyuasPinnes hauv rwb thaiv tsev(Ntau yam hauv Cables).
Qhov sib txawv:AC kev sim kev ntxhov siab rwb thaiv tsev tsis sib haum tab sis pheej hmoo tawm tsam; DC kev sim muaj kev nyab xeeb dua rau cov peev xwm txav mus tab sis qeeb qeeb.
Cas hipot kuaj ua haujlwm: kev tshawb fawb
Lub hauv paus ntsiab lus:Thov thov 1.5-3 x o operating voltage rau 1-5 feeb.
Cov cim tsis ua haujlwm:Tam sim no kav dej> preset throholhold =} rwb thaiv tsev tawg.
Cov tswv yim tseem ceeb:Nws tsis yog "dhau / swb" -to tam sim no cov qauvQhia tawm cov kev laus (piv txwv li, ib nrab tawm hauv hloov pauv).
Cov ntawv thov: qhov chaw hipot txuag lub neej
Fais fab fab:Tiv thaiv kev tawg xaim cable tawg.
Switchgear:Zam arc flashes nyob rau hauv kev hloov.
Cov Neeg Siv Khoom Hluav Taws Xob:Ua kom muaj kev ua raws li IEC / MP tus qauv kev nyab xeeb.
Piv Txwv Piv Txwv:Lub tuam txhab hluav taws xob hloov kho qhov kev sib tw tawm los ntawm kev ntes cov rwb thaiv tsev tsis zoo hauv ib qho kev sim HIPOT HIPOT.
Yuav ua li cas xaiv HIPOT cov lus tsis muaj: 4 qhov tseem ceeb
Voltage theem
Txoj Cai: AC sim {= 2} × ×ence Khiav Voltage {}} kv; DC sim=2 × × act voltage.
Kev sim ncua sijhawm
Txheem: 60 vib nas this. Ntev mus rau 15 mins rau kev ntsuas kev ntxhov siab.
Test Hom
Xaiv AC rau cov khoom sib xyaw, DC rau cov cable ntev lossis capactrativits.
Kev Nyab Xeeb Kev Nyab Xeeb
Dlhos nrog IEC 60255 (Repays), IEEE 433 (ulors), lossis ul 60335 (khoom siv).
Pro tswv yim:Yeej ib txwm sim ntawm25% -100% ntawm cov peev txheej ntsuasKom tsis txhob muaj kev puas tsuaj loj.
HIPOT Testing thiab rwb thaiv tsev tsis kam (IR) kuaj
| Yam | Kuaj ntshav hipot | IR TEST |
|---|---|---|
| Lub hom phiaj | Simulate phem tshaj -} kev ntxhov siab | Ntsuas Kev Noj Qab Haus Huv |
| Siv voltage thov | Kev puas tsuaj siab | Tsis - kev puas tsuaj (500v-5kv) |
| Zoo tshaj plaws rau | Pre6 - commressioning kev nyab xeeb | Kev Txij Nkawm Txij Nkawm |
Sab saum toj 3 kev coj ua kev nyab xeeb
Hauv av ua ntej kuaj:Kev tso tawm lub peev xwm txav mus kom tsis txhob poob siab.
Siv cov chaw taws teeb hluav taws xob:Muaj cov neeg ua haujlwm los ntawm cov chaw tiv thaiv ib cheeb tsam.
Saib xyuas cov pas dej tam sim no:Ib qho kev xav zoo li cas ntawm kev ua tsis tiav.
Vim li cas Hipot kuaj tsis yog - kev sib ceg
A hipot xeem voltagetsis yog ua raws li - nws yog aKev ntseeg plab txoj cai tuav pov hwmCov. Txog kev siv hluav taws xob, cov chaw tsim khoom, lossis cov neeg ua haujlwm saib xyuas, hla nws pheej hmoo hluav taws, downtime, thiab tswj kev nplua. Raws li ib tus kws ua choj sau tseg:
"Ib tug 5konhiptogavavavavas2m hauv transformer hloov."
Ua kom tiav koj lub tswv yim kev sim siab niaj hnub no -Vim tias rwb thaiv tsev ua tsis tiav yog ib txwm tsis muaj kev xaiv.
