Umkhiqizo Odume Kakhulu - I-CNAISO Ground Resistance Tester

1,UhlolojikelelekweI-Ground Resistance Tester.

I-universal grounding resistance tester isetshenziselwa ukukala inani lokumelana phakathi kwe-casing yamamotho ahlukahlukene, izinto zikagesi, izinsimbi, izinto zasendlini nezinye izinto zokusebenza kanye nendawo yazo yamandla.Ithuluzi linokuhlolwa kwegiya lesibili lamanje (AC: 25A noma AC: 10A), kanye nesilungiselelo sesikhathi sokuhlola (1~99S).Uma inani elilinganisiwe lidlula u-100mΩ (AC 25A) noma 200mΩ (AC 10A), linomsebenzi we-alamu yomsindo nokukhanya, futhi inomsebenzi wokuvikela i-overcurrent (AC 30A).Insimbi isebenzisa amadijithi angu-31/2 ukuze ibonise, futhi ukufundwa kulula futhi kunembile.Ithuluzi lamukela umgomo wokuhlukanisa ukulinganisa, futhi ukushintshashintsha kwamandla okuhlola ngeke kuthinte ukunemba kokulinganisa, ngakho-ke inezinzuzo zokulinganisa okunembile, ukusebenza okulula kanye nosayizi omncane.Ukuthembeka okuphezulu nezici eziphezulu.

2. Izici zeI-Earth Resistance Tester?

2, 3, 4-pole indlela yokuhlola ukumelana nomhlabathi

Indlela yokubopha eyodwa yokuhlola ukumelana nomhlabathi

Ukumelana nomhlabathi wokuhlola umhlathi okabili

Umsebenzi wokuhlola ukumelana nomhlabathi

Umsebenzi wokuhlola wamanje (RMS).

Ithuluzi linokusebenza okuqinile kokulwa nokuphazamiseka

Ama-alamu wezimo zokuhlola ezingaphandle komkhawulo noma ezingalungile

I-1000 test memory kanye nesoftware yokuhlaziya

Amandla ebhethri aphinde ashajwe, umsebenzi wokuvala shaqa okuzenzakalelayo

3.Indlela yokusebenzisa i-umhloli wokumelana nomhlabathi ?

3.1.Ithuluzi lifakwe ipheya elilodwa (amasethi amabili) ezintambo zokulinganisa.Amapulaki amakhulu namancane eqembu lezintambo ezibomvu axhunywe ngokulandelana kwawo kumasokhethi okuhlola A kanye no-a womhloli, futhi amapulaki amakhulu namancane eqembu lezintambo ezimnyama axhunywe ngokulandelana kwawo kumasokhethi okuhlola omhloli B no-b.

3.2.Vula amandla, vula iswishi yamandla, futhi ishubhu yedijithali yesibonisi izokhanya.

3.3.Khetha inkinobho yokuhlola ububanzi yamanje engu-25A noma engu-10A njengoba kudingeka.25Ububanzi uma iswishi icindezelwa;10A ububanzi lapho iswishi ikhishwa.

3.4.Guqula iknobhu yamanje yokulungisa ngokuphambene newashi ibe uziro.

3.5.Xhuma iziphetho zesiqeshana zamasethi amabili angenhla emigqa yokulinganisa ezindaweni zokuhlola zento ezokalwa.

3.6.Ukulinganisa okwenziwa ngesandla

(1) Setha iswishi yesibali sikhathi ibe yisimo “sokwenziwa ngesandla”.

(2) Ngemva kokuhlola ukuthi izinyathelo 3-5 zilungile, cindezela inkinobho ethi “Qala”, isibani esithi “Test” sivuliwe, lungisa inkinobho ethi “Ukulungiswa Kwamanje” bese ubheka inani lamanje esibukweni nenani lamanje elikhethiwe, futhi bese ufunda ukumelana okukhonjiswa esibukweni.Ukufunda, lapho ukumelana komhlabathi kwento elinganisiwe kukhulu kunevelu ye-alamu yokumelana nesisekelo esethwe ifayela lamanje, ithuluzi lizothumela i-alamu yomsindo nokukhanya, ngaphandle kwalokho, ngeke ishaqise.Uma udinga ukumisa ukuhlola, cindezela inkinobho ethi "Setha kabusha", ukukhanya "Hlola" kuzocisha, i-loop current izonqanyulwa, futhi isiqeshana sokuhlola sizokhishwa entweni evivinywayo ukuze kuthathwe isilinganiso esilandelayo.

3.7.Isilinganiso sesikhathi

(1) Sethela ithuluzi esimweni “sokusetha kabusha”.

(2) Cindezela inkinobho ethi “isikhathi” uye endaweni “yesikhathi,” bese usetha kusengaphambili isikhathi sokuhlola esidingekayo njengoba kudingeka.

(3) Ngemva kokuhlola ukuthi izinyathelo 3 kuya kwezi-5 zilungile, cindezela inkinobho ethi “Qala”, isibani esithi “Test” sivuliwe, isibali sesikhathi sokubonisa siqala ukubala siye phansi, lungisa inkinobho “Yokulungisa Kwamanje” futhi ubuke inani lamanje lokubonisa. enanini lamanje elikhethiwe, Bese ufunda ukufundwa kokumelana okuvezwe esikrinini sokubonisa.Lapho ukumelana komhlabathi kwento elinganisiwe kukhulu kunevelu ye-alamu yokumelana nesisekelo esethwe ifayela lamanje, ithuluzi lizothumela i-alamu ezwakalayo nebonakalayo, ngaphandle kwalokho, ngeke ishaqise.Uma isikhathi sokuhlola sesiphelile, iluphu yamanje inqanyulwa ngokuzenzakalelayo, futhi isiqeshana sokuhlola singasuswa entweni evivinywayo ukuze kulinganiswe okulandelayo.

3.8.Leli thuluzi linokuvikela okudlulele, lapho iluphu yamanje idlula 30A,

Ithuluzi linikeza inkomba ye-overcurrent (ukukhanya kwe-overcurrent kuvuliwe), futhi inqamula ngokuzenzakalelayo iluphu yamanje.Cindezela inkinobho ethi “Setha kabusha” ukuze ukhansele isimo se-alamu, bese uphendulela inkinobho ethi “Ukulungiswa Kwamanje” ngokuphikisana newashi libe inani elincane lesilinganiso esilandelayo.

4.Kungani u-Yueqing AIso?

4.1: Ubunjiniyela obugcwele nokusekelwa kobuchwepheshe: abakhiqizi abangochwepheshe abangu-3, ​​nethimba lesevisi yezobuchwepheshe.

4.2: Ikhwalithi ingu-No1, isiko lethu.

4.3: Izikhathi zokuhola ngokushesha:“Isikhathi siyigolide” kuwe nakithi

4.4: 30min impendulo esheshayo: sineqembu lochwepheshe, 7 * 20H

Thola ukwethenjwa kweklayenti ngenxa yedumela labo elifakazelwe lokuthembeka, ukusebenza nempilo ende.

Uma unombuzosnoma yiziphi izidingo zomkhiqizo, sicela ukhululeke ukuxhumana nami.
