Lub hauv paus rau phau ntawv
DC hipot(Muaj peev xwm siab) kev sim yog qhov tsis - rwb thaiv tsev ntawm cov cable, hloov pauv, thiab lwm yam siab {voltage khoom siv. Los ntawm kev thov ib qho kev tswj hwm DC voltage, nws txheeb xyuas cov kev tsis muaj zog uas tuaj yeem ua rau poob ua tsis tiav lossis phom sij. Ntawm no yog li cas nws ua haujlwm thiab vim li cas nws tseem ceeb.
Tus tub ntxhais ua hauj lwm txoj cai
SC HIPOT Tester Siv Ib Qhov Hluav Taws Xobsiab dua cov khoom siv ua haujlwm voltageThoob plaws nws rwb thaiv tsev. Tsis zoo li AC cov kev ntsuam xyuas, DC voltagetsis tsim tawm caportitive keb, Cia nws kom tsom ntsoov rau ntawm rwb thaiv tsev tsis kam. Qhov kev ntsuas ntsuas:
To tam sim no: Cov dej qab zib ntws los ntawm cov rwb thaiv tsev tsis xws luag.
TIM DAWB VALPETage: Qhov uas rwb thaiv tsev thaiv kev.
Vim li cas DC dhau AC?
DC kev tshuaj ntsuam xyuas kom tsis txhob muaj peev xwm them nyiaj, txo txoj kev pheej hmoo ntawm kev ua tsis tiav.
Nws yog qhov zoo tagnrho rau lub peev xwm capacitive (piv txwv li, cles ntev) txij li DC Charges Rwb thaiv tsev maj.
Cov kauj ruam tseem ceeb hauv aDC hipotXeem ntawv
Kev npaj: Av cov khoom siv thiab teeb tsa voltage (piv txwv li, 2 × kev ua haujlwm hluav taws xob voltage {}} kv).
Ramp -}: Maj mam nce voltage kom tsis txhob surges.
Nyob rau lub sijhawm: Siv voltage rau 1-5 feeb thaum soj ntsuam teakage tam sim no.
Kev Tshawb Xyuas:
Daim pib: Takeage tam sim no tseem ruaj khov thiab hauv qab hreshols.
Ua tsis tau: Cov spikes tam sim no qhia rwb thaiv rwb thaiv tsev.
Daim ntawv thov tseem ceeb
Lub zog fais fab: Txheeb xyuas cov dej noo cawv lossis kev puas tsuaj hauv cov cables hauv av.
Kev hloov pauv: Uncitipers winding rwb thaiv tsev tsis muaj zog.
Ev Cheebtsam: Siv tau roj teeb cov roj teeb thiab cov chaw nres nkoj them.
Piv txwv li:
Lub tuam txhab hluav taws xob zam kev sib tw ntawm kev siv DC hipot kuaj kom pindique degraded hauv 10 kV cable txi ua ntej nws ua tsis tau tejyam.
Vim Li Cas Rwb Thaiv Tsev Cov Tsis Txaus Siab
Txawm tias tsom iav pob tawg lossis cov paug hauv rwb thaiv tsev tuaj yeem ua:
Tso Rau Lwm Tiam: Me me sparch yaig rwb thaiv tsev dhau sijhawm.
Thermal khiav khiav: Tshav kub txhim kho los ntawm to to furents.
Dc hipot qhia tawm cov flaws ntawmCov qib qisTshaj kev ua haujlwm tsis ua hauj lwm, tiv thaiv hluav taws lossis hluav taws xob.
Kev Nyab Xeeb Kev Nyab Xeeb
Txo kev pheej hmoo ruaj khov: DC kev tshuaj ntsuam siv lub zog tsawg dua AC, txo qis kev puas tsuaj yog tias tsis ua haujlwm.
Tsis muaj lub peev xwm: Kev nyab xeeb dua rau kev sim cov khoom sib xws li capacitors.
Xaiv ADC hipotTester
Saib rau:
Adjustable voltage ranges: Rau kev sim cov khoom siv sib txawv.
Txoj kev tswj hwm: Tiv thaiv cov hluav taws xob volfage.
Take Nrig Tam Sim No: Qhov tseem ceeb rau kev kuaj me me flaws.
Kawg xav
DC Hipot Kuaj tsis yog ib kauj ruam ua raws li - nws yog qhov kev tiv thaiv hluav taws xob tiv thaiv hluav taws xob. Los ntawm kev nkag siab txog nws lub neej ua haujlwm, engineers tuaj yeem kuaj pom zoo dua cov kev pheej hmoo thiab txuas ntxiv cov cuab yeej siv sia.
Kev xeem cov kev sib tham tsis tu ncua los ntawm cov tsis muaj zog cuam tshuam rau hauv kev tiv thaiv kev nyab xeeb.
