I-Grounding kanye ne-Equipotential Bonding ye-Explosion-Proof Electrical Equipment

Izinto zikagesi ezingaqhumi kufanele zibe namabhokisi ensimbi asekelwe phansi. Ukwengeza, i-equipotential bonding iyadingeka ukuze kuvinjwe ukuvuza okungase kube khona ngenxa yokwehluleka kokufakwa ngaphakathi nokugwema ingozi yezinhlansi zikagesi ezivela emisinga enhlanhlathayo evutha ingxube yegesi eqhumayo..

Okokusebenza okunjalo, isibopho esiyisisekelo kanye ne-equipotential kufanele kusetshenziswe ohlelweni olukabili, lapho idivayisi ngayinye ifakwe kokubili amatheminali aphansi angaphakathi nangaphandle. Lawa matheminali kufanele agcinwe esesimweni esifanayo futhi axhunywe ku- ukubeka phansi uhlelo lokuqinisekisa ukusebenza kahle kwesisekelo kanye nokubopha.

Isisekelo sangaphakathi kufanele simiswe ngaphakathi kwendawo yokufaka izintambo (ibhokisi lokuhlangana noma igumbi elikhulu), futhi isisekelo sangaphandle kufanele sibekwe ebhokisini eliyinhloko ledivayisi. Lokhu kuqinisekisa ukuthi izingxenye zensimbi ezinkulu zedivayisi, njengohlaka, zinamandla afanayo nomhlabathi.

Amakhondaktha asetshenziselwa ukubeka phansi kanye ne-equipotential bonding kufanele ahlangabezane nendawo encane enqamula ingxenye, S. Kumjikelezo oyinhloko wesigaba esisodwa, uma indawo ye-cross-sectional S0 ingekho ngaphezu kuka-16mm², bese u-S okungenani abe ngu-S0. Ku-S0 phakathi kuka-16mm² kanye no-35mm², I-S kufanele ibe ngu-16mm². Uma i-S0 idlula u-35mm², U-S kufanele abe ngaphezu kwesigamu sika-S0. Uma i-S0 incane kakhulu, ubuncane bendawo ephambanayo kufanele okungenani ibe ngu-4mm².

Ithuluzi ngalinye le-grounding ne-equipotential bonding kufanele liqinisekise ukuxhumana okuthembekile phakathi kwamakhondakta namatheminali aphansi, ngezinyathelo zokuvimbela ukuxega noma ukugqwala.

Okwezinto zikagesi eziphathwayo ezinikwa amandla yigridi, isisekelo sangaphandle singadlula, kodwa ukubeka phansi kwangaphakathi kufanele kwenziwe kusetshenziswa ikhebula elinomnyombo ophansi. Uma inikwa amandla iphakethe lebhethri elinezigxobo ezingagxiliwe, ukugxilisa akudingekile. Ukwengeza, amadivaysi kagesi ane-insulation ephindwe kabili noma eqinisiwe akufanele abekwe phansi.
