Indlela yokusebenzisa umhloli wokumelana nomhlabathi

Ukumelana ne-Grounding idivayisi evame ukusetshenziswa ekuhlolweni kwemboni yamandla, ngakho-ke isetshenziswa kanjani ngendlela efanele?

GDCR3000C Grounding Resistance Tester

1. Okokuqala, hlola ukuthi ingabe ulayini wamanje, ulayini we-voltage kanye nolayini wenethiwekhi yomhlabathi osetshenziselwa ukuhlolwa uvulekile, ukuthi ukugqwala kwenqwaba yomhlabathi kukhishwe ngokuhlanzekile, nokuthi ukujula okungcwatshwe kufanelekile.Ngesikhathi esifanayo, hlola ukuthi ukuxhumana phakathi komugqa wokuhlola kanye nenqwaba yomhlabathi kuxhunyiwe.Vuliwe, sicela uxhume kabusha ngemva kokucubungula.

2. Isilinganiso sobude bomugqa wokuhlola wamanje emgqeni wokuhlola i-voltage ngu-1: 0.618, futhi ubude bomugqa wokuhlola wamanje kufanele kube izikhathi ezingu-3-5 i-diagonal yegridi yomhlabathi.

3. Xhuma isiphetho esisodwa somugqa wokuhlola wamanje kanye nolayini wokuhlola i-voltage ensimbini ngokuya ngobude obuvamile bese uzikhulula ngokuhambisana.Ezinye iziphetho zixhunywe ezigxotsheni ezimbili zomhlaba ngokulandelanayo.

4. Hlola umugqa wokuhlola wesihloli sokumelana nesisekelo somhlaba wonke futhi, bese usisebenzisa ngokusemthethweni ngemva kokuqinisekisa ukuthi silungile.

5. Ngemva kokuhlola ukuthi uxhumano lulungile, xhuma amandla ensimbi namandla ensimbi.

6. Cindezela inkinobho yokulinganisa ukuze uqale ukulinganisa.

7. Ngemva kokuba ithuluzi libonise isivivinyo, rekhoda idatha yokuhlola.

8. Ngemva kokuvala amandla ensimbi, susa uxhumano, futhi inqubo yokuhlola iphelile.

Iziqondiso ezijwayelekile zokusebenza komhloli wokuqina wokuqina (ngokwereferensi kuphela):

1. Vula iswishi yamandla, futhi ikhompuyutha izozihlola yona.

2. Hambisa ikhesa entweni ngayinye yemenyu kanye nomjikelezo ukuze ubonise.Into ekhethiwe iboniswa kufonti emhlophe ehlehlayo.

3. Entweni evezwe yikhesa njengamanje, cindezela izinkinobho zaphezulu naphansi ukuze ushintshe imenyu, kanye nemiyalelo yokujikeleza.

4. Ngemva kokushintsha imenyu ukuze ihambisane nezidingo zokuhlola, ungacindezela inkinobho yokukhetha ukuze ukhethe into elandelayo.
