DC Ground Fault Finder

Portable DC Ground Fault Locator

Lub portable DC hauv av fault locator siv lub siab -precision tam sim no clamp meter los xyuas thiab txheeb xyuas qhov txhaum los ntawm kev ntsuas qhov sib txawv ntawm DC tam sim no nyob rau hauv lub faulty circuit. Los ntawm kev sib koom ua ke ceev FFT thev naus laus zis rau hauv DC qhov tsis raug cov cuab yeej tshawb nrhiav, nws tuaj yeem txheeb xyuas ntau yam kev cuam tshuam ntawm rwb thaiv tsev, DC cross-kev ua txhaum cai, thiab AC hla-kev ua txhaum cai hla txhua theem voltage (24V, 48V, 110V, 220V) hauv DC systems. Cov cuab yeej no muaj qhov ntsuas pom tau zoo, muaj zog tiv thaiv- muaj peev xwm cuam tshuam, qhov loj me, lub teeb yuag, thiab cov neeg siv- ua haujlwm zoo. Thaum nrhiav DC system hauv av faults, nws yuav tsum tsis muaj hluav taws xob cuam tshuam thiab ua kom meej meej grounding point localization. Cov cuab yeej ntsuas DC system grounding resistance values ​​thiab txiav txim siab grounding direction, muab ib tug txhim khu kev qha, siab -cov cuab yeej nrhiav kom tau tseeb rau nrhiav thiab pinpointing av faults nyob rau hauv lub hwj chim DC systems.

Raws li lub tshuab hluav taws xob xav tau kev ruaj ntseg ntxiv rau kev ua haujlwm, qhov kev xav tau rau kev tshawb nrhiav DC siab heev yuav loj tuaj. Yog li ntawd, kev ntsuas siab thiab kev ntsuas hluav taws xob rwb thaiv tsev yuav dhau los ua qhov yuav tsum tau ua rau tiam tom ntej ntawm portable DC av txhaum locators hauv lub tshuab hluav taws xob.

Tus tshiab portable DC av txhaum locator, raws li lub hauv paus ntsiab lus ntawm DC tam sim no sib txawv nrhiav kom tau, koom nrog ceev FFT transformation technology. Los ntawm kev soj ntsuam cov ncauj lus kom ntxaws ntawm qhov amplitude - tus yam ntxwv zaus ntawm qhov ntsuas qhov ntsuas, nws ntsuas qhov tsis sib haum xeeb xav tau ntawm kev nyab xeeb thiab rhiab heev hauv DC hauv av txhaum qhov chaw. Qhov kev nce qib no txhawb nqa DC hauv av txhaum kev tshawb nrhiav thev naus laus zis mus rau qib tshiab, muab cov ntawv thov dav dav.

1. Qhov ntsuas no muaj lub teeb liab transmitter (analyzer) thiab receiver (locator). Lub analyzer rub lub zog ncaj qha los ntawm lub busbar, tshem tawm qhov xav tau rau sab nraud AC lossis roj teeb lub zog, ua haujlwm yooj yim dua;

2. Nws daws txhua qhov txhaum hauv av, suav nrog:

- Tsis zoo rwb thaiv tsev ua rau phantom grounding

- Siab -tsis kam grounding

- Ntau - taw tes hauv av

- Ib qho - taw tes hauv av

- Tsawg- tsis kam grounding

- Direct grounding

- Sib tov - kab hauv av

- Loop grounding

- Capacitive grounding

- AC leakage grounding

- Transistor cais grounding

3. Ua kom tiav DC system grounding faults. Tsis muaj kev cuam tshuam los ntawm kev faib tawm loj hauv thaj teb, nws raug txheeb xyuas thiab nrhiav qhov tsis raug hauv thaj chaw me tshaj plaws.

4. Qhia meej meej txog cov kev taw qhia ntawm cov teeb liab hauv av tam sim no, ua kom paub ceev ceev ntawm qhov yuam kev;

5. Muab lub suab tshaj tawm hais txog qhov xwm txheej hauv av thiab kev taw qhia;

6. Precisely pom qhov loj thiab theem ntawm kab xau tam sim no, sai thiab raug qhov chaw qhov txhaum raws li kev hloov pauv tam sim no hauv qhov dej ntws tam sim no thiab theem ua ntej thiab tom qab qhov chaw txhaum;

7. Ib qho DC grounding analyzer ua haujlwm rau txhua lub tshuab DC hauv qab 300V, tsis muaj qhov tshwj xeeb ntxiv rau DC voltage;

7. Tag nrho touchscreen ntse tsim rau txhim kho usability; tsis muaj khawm tswj yuav tsum tau. Qhov siab tshaj qhov teeb meem tam sim no<800μA with built-in current limiting protection, ensuring no impact on relay protection, automation devices, or operating circuits for safe operation;

8. Ripple tsom xam thiab digital oscilloscope functionality: Siv spectrum tsom xam kom tshem tawm ntau yam cuam tshuam cov teeb liab thiab saib waveform cov ntaub ntawv ntawm nrhiav pom thiab circuits;

9. Kev txawj ntse tam sim no clamp tau pom qhov qhib / kaw, sib xws nrog ob lub puab tsaig loj thiab me;

10. Adaptable rau hauv av faults tshwm sim los ntawm AC / DC cross-conduction, nplhaib network mov grounding, diode- cais mov grounding, thiab siab - resistance grounding;

11. daws tib yam -ncej / txawv-ncej DC cross-kev ua txhaum cai thiab txheeb xyuas cov ceg tsis raug;

12. Txhawb chaw nres tsheb fais fab khoom siv nrog ntau yam specifications thiab av capacitance, ntsuas busbar capacitance qhov tseem ceeb;

13. Ceev nrooj nrhiav cov teeb meem hauv av yam tsis muaj kev teeb tsa, hluav taws xob tawm, kev sib txuas ntawm cov xov hlau, lossis kev ntsuas hluav taws xob;

14. Tus neeg siv- tus phooj ywg ntse kov interface rau kev ua haujlwm yooj yim, ntim hwm kom yooj yim txav mus los.

MEZN-WZA40 Portable DC Ground Fault Locator yog tsim los rau kev daws teeb meem DC system faults thoob plaws ntau yam xwm txheej, nrog rau cov ntawv thov tseem ceeb suav nrog:
