Shenhai Explosion-Ubungqina
Isixhobo sombane esingagqabhukiyo kufuneka sibe nezingxobo zentsimbi ezisekelwe phantsi. Ukongeza, i-equipotential bonding iyimfuneko ukunqanda imisinga evuzayo enokubakho ngenxa yokusilela kokugquma kunye nokunqanda umngcipheko weentlantsi zombane ezivela kwimisinga elahlekileyo elayita imixube yerhasi eqhumayo..
Kwizixhobo ezinjalo, isiseko kunye ne-equipotential bonding kufuneka iphunyezwe kwinkqubo emibini, apho isixhobo ngasinye sixhotyiswe ngeetheminali zokumisa zangaphakathi nangaphandle. Ezi theminali kufuneka zigcinwe zikwisakhono esifanayo kwaye ziqhagamshelwe kwi isiseko inkqubo yokuqinisekisa ukusebenza kakuhle kwesiseko kunye nokudibanisa.
Isiseko sangaphakathi kufuneka simiselwe ngaphakathi kwendawo yokubeka iintambo (ibhokisi yesiphambuka okanye igumbi eliphambili), kunye nesiseko sangaphandle kufuneka sibekwe kwindawo ephambili yesixhobo. Oku kuqinisekisa ukuba izixhobo eziphambili zetsimbi zesixhobo, njengesakhelo, zinamandla afanayo nomhlaba.
Abaqhubi abasetyenziselwa ukumisa kunye ne-equipotential bonding kufuneka bahlangabezane nobuncinci bendawo enqamlezileyo, S. Kwisekethe eyintloko yesigaba esinye, ukuba indawo enqamlezileyo i-S0 ayikho ngaphezulu kwe-16mm², emva koko u-S kufuneka abe ngu-S0. Kwi-S0 phakathi kwe-16mm² kunye ne-35mm², S kufuneka ibe yi-16mm². Ukuba i-S0 ingaphezulu kwe-35mm², U-S kufuneka abe ngaphezu kwesiqingatha sika-S0. Ukuba i-S0 incinci kakhulu, ubuncinane bommandla onqamlezileyo kufuneka ubuncinane ube yi-4mm².
Isixhobo ngasinye sokubeka phantsi kunye ne-equipotential bonding kufuneka siqinisekise uqhagamshelwano oluthembekileyo phakathi kwee-conductor kunye ne-grounding terminals, kunye nemilinganiselo yokuthintela ukukhulula okanye ukubola.
Kwizixhobo zombane eziphathwayo eziqhutywa yigridi, isiseko sangaphandle sinokugqithiswa, kodwa isiseko sangaphakathi kufuneka siqhutywe kusetyenziswa intambo kunye nesiseko sokumisa. Ukuba inikwe amandla yibhetri ipakethi eneepali ezingasekelwanga, ukumisa akubalulekanga. Ukongeza, izixhobo zombane ezine-insulation ephindwe kabini okanye ezomeleziweyo akufanele zibekwe phantsi.
