Ngempumelelo phansi nentaba

Ukuze aqaphe womuntu emiphumeleni elimazayo property kagesi osetshenziswayo ekhethekile zokuzivikela kudivayisi RCD, fuses, MCB (wesifunda amadlambi) nezinye izici zokuphepha. Uhlelo ethandwa iningi ukulondeka kwabantu ubhekwa ukunquma nentaba bomhlaba. Le divayisi ethile earthing ogama njongo iwukuba ukuxhuma kwi "phansi" kwezicucu ngasinye zikagesi. Noma, ngamanye amazwi, axhumene ku electrode evundla mpo (diverters), ibekwe ngaphansi kwamanzi emhlabathini Ekujuleni.

On ukumelana circuit kuthintwa:

• uthayiphe, isakhiwo kanye isimo kwenhlabathi;
• izindawo electrode;
• Ukujula electrode nesenzakalo;
• inani electrode.

phansi Functional ihlukaniswe ezimbili izinhlobo:

• Ukuvikelwa - eyenzelwe ukuvikela amadivayisi ugesi isekhethi, abantu kusuka emiphumeleni elimazayo imisinga kuyingozi ukuthi kwenzeke ngesikhathi iphutha.
• Abasebenzi - Isekela oyifunayo ukusebenza ukufakwa kagesi nge isisekelo yezingxenye zayo bukhoma.

Inqubo yokudala nentaba

Ungesabi of umbuzo zendlela yokwenza iluphu phansi, ngoba ukuqoqa kuyo umkhuba, akusho zinkinga ezinkulu. Ekhuluma ewukuhlakanipha okwenziwe divertors ngoba isisekelo angase afanelekele metal engeli nge ububanzi engxenyeni 45 noma 60 mm, amapayipi ka diameters ezahlukene. Isisekelo isikimu ku ifomu unxantathu muhle ngoba uma kungenzeka yini ukuthi kwephulwe uxhumano diverter kwelinye imigqa, imigqa parallel ukuhlala nokusebenza.

Kuhle ukuhanjwa obandayo wesifunda peaty Inhlabathi loamy nenhlabathi nobumba ngezinga eliphezulu umswakama. Uhlobo okubi kakhulu inhlabathi - hlabathini onamadwala.

Kunconywa ukuba ukhethe indawo ethize ukuze abuthele phansi iluphu, indawo elikhulu kubhekwe njengento ezizungeze switchgear. Isisekelo kufanele wenziwe Alloys ithusi noma steel black noma lashukumisa ngaphandle imidwebo.

Lokwela bemba umsele ngendlela unxantathu, ezinhlangothini 3 metres, ukujula incane - 0.5-0.8 metres. Vertices unxantathu okhandwe ngesando steel earthing obuphelele 2.5-3 m. Imikhawulo kungenziwa ngensimbi kuya metal kulula ukubeka phansi. Ngenhla phansi inqolobane kancane, kuze kufinyelele 20 cm, is eziphothene kuya steel ovundlile ukuhlubula kubo, okuholela amandla isihlangu kagesi. weld ngeke engadingekile ukusingatha anti-ukugqwala upende noma, isibonelo, itiyela.

Ngemva obandayo usebenze nesilinganiso wesifunda phansi, lapho nesilinganiso control wenziwa ukumelana layo ezingeni. Lokhu kwenziwa yidivayisi, othiwa megohmmeter. Kamuva okuphindaphindiwe izilinganiso ezenziwe okungenani isikhathi esingu-1 ngonyaka. Ngenxa yale njongo ngokusebenzisa kudivayisi isisekelo kumelwe ukuvala wesifunda kanye yokufakelwa kagesi ke ukwenza control izilinganiso ekudonseleni wesifunda voltage. Eduze electrode main ngokufanele elisizayo ixhume umthombo. Imitha fixed ezingaba eduze zero ezidlula we voltage iconsi phezu electrode main. Le ndlela has circuit isisekelo kukalwa kaningi kunezinye izindlela.
