Feem ntau muaj ob txoj hauv kev los saib xyuas cov rwb thaiv tsev ntawm cov khoom siv hluav taws xob hluav taws xob siab hauv cov chaw nres tsheb: kev saib xyuas online thiab nyob (portable) nrhiav pom hauv online.Tus qub tuaj yeem tau txais cov yam ntxwv tsis zoo uas cuam tshuam qhov txawv txav ntawm cov khoom siv txhua lub sijhawm, uas yooj yim rau kev tswj tsis siv neeg.Txawm li cas los xij, kev nqis peev yog qhov loj heev, kev teeb tsa thiab kev tsim kho kuj muaj teeb meem, thiab kev saib xyuas tsis tu ncua yog xav tau.Rau qhov tom kawg, nws muaj qhov zoo ntawm kev nqis peev tsawg, siab heev, yooj yim rau nruab, tswj thiab hloov kho.Raws li ntev raws li cov qauv ntsuas tau nruab rau hauv cov khoom siv hluav taws xob ua ntej, kev tshawb nrhiav tsis tu ncua tuaj yeem ua rau cov khoom siv hluav taws xob hauv kev ua haujlwm, thiab qhov cuam tshuam ntawm rwb thaiv tsev tuaj yeem pom nyob rau lub sijhawm, txhawm rau ncua lub sijhawm pretest ntawm lub zog tsis ua haujlwm thiab hloov pauv tag nrho. -kab saib xyuas txoj kev.

GDDJ-HVC dielectric poob tester rau cov khoom siv nyob hauv capacitive tuaj yeem siv los ntsuas dielectric poob thiab capacitance ntawm cov khoom siv capacitive (bushing, CT, CVT, coupling capacitor), thiab xyuas qhov tsis zoo ntawm rwb thaiv tsev.

Nta

1. Sab nraud lub qhov tam sim no sensor nrog siab precision feem ntau yog siv los ntawm cov tsoos sampling unit, uas muaj xws li ntau tshaj ib tug hloov Circuit Court.Thaum lub sij hawm sim, ntau lub tab luv luv yuav tsum tau ua rau qhov kawg tiv thaiv tam sim no rau kev ntsuas ntsuas.GDDJ - HVC siv cov qauv ncaj nraim los ntawm cov qauv, tuaj yeem ntsia tau ze ntawm cov khoom siv, cov hlau lead ntawm qhov kawg shielding tsis tawg thiab qhov ntev yog luv heev, uas tsis txhob qhib Circuit Court ntawm qhov kawg shielding.Lub sensor tuaj yeem kuaj pom cov teeb liab hauv 100μA ~ 700mA.Impedance ntawm sensor yog tsawg, tuaj yeem tiv taus lub zog zaus tam sim no 10A thiab xob laim impulse tam sim no 10kA, ua tau raws li kev siv ntawm kev tshawb pom hauv online.

2. Cov qauv coj mus kuaj tau txais kev tuag-casting txhuas plhaub sealing waterproof tsim, thiab txais yuav waterproof cable connector rau lwm cov zis, uas yog yooj yim rau kev twb kev txuas;Tom qab lub sensor tau teeb tsa, nws ib txwm tsis muaj zog.Rau kev sim, tsuas yog cov kab txuas txuas ntxiv ntawm cov qauv ntsuas yuav tsum tau txuas nrog, thiab "plug thiab ua si" tuaj yeem ua tiav yam tsis muaj kev ua haujlwm ntawm qhov kawg tiv thaiv lub teeb liab cable.

3. Cov txheej txheem tseem ceeb ntawm cov cuab yeej yog American TI 32-ntsis ntab-point siab ua haujlwm digital teeb liab processor (DSP), uas khiav lub sijhawm ua haujlwm ntawm lub sijhawm tiag tiag thiab siv qhov txuas ntxiv 16-ntsis, high-speed, multi-channel synchronous sampling analog digital converter (A / D) kom paub qhov ntsuas lub sij hawm thiab kev ntsuas siab ntawm cov ntsuas ntsuas.Muaj peev xwm saib xyuas ntau yam khoom siv ib txhij.

4. Ob txoj kev tshawb nrhiav hauv online rau dielectric poob tuaj yeem muab tau, uas tuaj yeem ntsuas qhov sib txawv ntawm dielectric poob thiab qhov sib piv ntawm ob lub capacitive li tib theem, thiab PT theem nrab voltage yuav siv tau raws li cov teeb liab siv los ntsuas qhov capacitance thiab dielectric. poob ntawm lub cuab yeej.Siv cov khoom siv nyiaj tam sim no thiab cov thev naus laus zis thev naus laus zis thev naus laus zis, qhov teeb meem ntawm dielectric poob qhov tseeb thiab ruaj khov yog daws, ua ke nrog kev ntsuas hluav taws xob zoo tshaj plaws thiab cov txheej txheem ua haujlwm siab heev, cov lim dej digital tuaj yeem ua kom cov txiaj ntsig ntawm dielectric poob tsis cuam tshuam los ntawm kev cuam tshuam kev cuam tshuam. thiab mem tes cuam tshuam, nrog rau qhov tseeb txog li ± 0.05%.

5. Nrog rau kev tshawb pom ntawm dielectric poob qhov sib txawv thiab qhov sib piv ntawm cov khoom siv hauv-theem capacitive, nws tuaj yeem tsis tsuas yog zam qhov cuam tshuam ntawm dielectric poob qhov kev sim tshwm sim los ntawm kev siv PT theem nrab voltage raws li cov cim qhia, tab sis kuj pab txo qis kev cuam tshuam ntawm theem-rau-theem hluav taws xob teb cuam tshuam.

6. Lub tshuab ntes tau nruab nrog lub vijtsam LCD loj rau kev saib xyuas qhov voltage, tam sim no, dielectric poob, resistive tam sim no, capacitive tam sim no thiab lwm yam ntaub ntawv.

7. Tus tester tsis tsuas yog muaj lub luag haujlwm ntawm kev tshawb nrhiav nyob, tab sis kuj tuaj yeem saib xyuas cov khoom siv hauv online tau ntev, thiab cia li kaw cov ntaub ntawv soj ntsuam.

8. Lub kaw lus tau txais cov sensors sab nraud es tsis txhob "cov qauv qauv", uas tuaj yeem hloov kho tau yooj yim los ntawm "nyob nrhiav pom" mus rau "kev saib xyuas online" raws li kev ua haujlwm ntawm cov khoom siv.Tsis tas yuav tshem tawm cov sensors uas tau teeb tsa, tsis tas yuav lov tes taw lub cuab yeej, tsuas yog ntxiv ib chav saib xyuas (IED).

9. Lub tshuab ntes tau txais cov qauv tsim, yooj yim rau kev khiav lag luam, lub roj teeb lithium hauv lub tshuab tuaj yeem tswj tau 8 teev ntawm lub sijhawm ua haujlwm tas mus li, ua tau raws li qhov yuav tsum tau ua ntawm kev siv teb.
