GDPD-306M Portable Ultrasonic Partial Discharge Detector
GDPD-306M yog dav siv nyob rau hauv ib feem ntawm kev kuaj pom ntawm lub tshuab fais fab.Xws li high voltage switchgear, lub nplhaib mains, voltage / tam sim no transformer, transformer (xws li qhuav hom transformer), GIS, overhead kab, cables, thiab lwm yam cuab yeej rwb thaiv tsev lub xeev nrhiav kom tau.
Cov ntsuas hauv qab no yog siv los ntsuas qhov ntsuas ntawm qhov tso tawm ntawm cov khoom siv hluav taws xob:
Kev kuaj pom ib nrab ntawm qhov paug tawm: Los ntawm kev ntsuas cov teeb liab tawm hauv lub voj voog lub zog, qhov kev siv ntawm ib nrab tawm yog tus cwj pwm raws li tus nqi siab tshaj plaws (dB) hauv qhov tso tawm pulse sequence.
Kev kuaj pom qhov tso tawm ib nrab: Lub cuab yeej ntsuas cov teeb liab tawm hauv lub voj voog lub zog, tshem tawm cov pa tawm tawm thiab qhia qhov zaus ntawm cov paug tawm raws li tus naj npawb ntawm cov pulses tawm.
●Nrog rau cov sensors sib txawv kom ua tiav ib feem ntawm kev kuaj pom ntawm yuav luag txhua yam khoom siv hluav taws xob.
●Muab ntau cov qauv tso tawm xws li lub sij hawm-domain waveform, PRPD, PRPS, thiab lwm yam, kom paub txog kev txheeb xyuas ntawm ntau hom paug tawm.
●Tus neeg siv-phooj ywg tus txiv neej-tshuab interface pab txhawb kev tswj cov ntaub ntawv ntawm cov khoom siv sib txawv, suav nrog kev taug qab ntawm cov ntaub ntawv keeb kwm hloov pauv, kab rov tav thiab ntsug cov ntaub ntawv txheeb xyuas, thiab paub txog 360 ° kev kuaj mob ntawm cov cuab yeej kuaj.
●Built-in ultrasonic sensor thiab lub ntiaj teb tam sim no voltage (tom qab no hu ua TEV) sensor, kuj tuaj yeem txuas nrog lwm cov sensors tshwj xeeb rau transformers, GIS, cov kab nyiaj siv ua haujlwm, thiab cables.
●Nws siv txoj kev tshawb nrhiav uas tsis muaj kev cuam tshuam, tsis tas yuav muaj hluav taws xob tawm thaum lub sijhawm kuaj, tsis tas yuav teeb tsa cov khoom siv hluav taws xob ntxiv, nws yooj yim dua los siv dua li cov khoom siv hluav taws xob ib nrab.
●Qhov ntsuas bandwidth ntau yog 30kHz ~ 2.0GHz, haum rau kev tshawb nrhiav cov qauv ntawm ntau zaus bands.
