Xa usebenza ngeenkqubo zombane, ngakumbi kwiindawo apho kukho amanzi okanye ukufuma, kubalulekile ukukhetha izihlanganisi zentambo ezifanelekileyo. Enye into ephambili ekukhetheni iziqhagamshelo kukuqonda ukukala kwabo kwe-IP (uKhuseleko lokuNgena). Olu kulinganisa lubonisa indlela isinxibelelanisi esikhuseleke ngayo eluthulini, emanzini, nakwezinye izinto zangaphandle. Kweli nqaku, siza kuphonononga ukuba kuthetha ukuthini ukulinganiswa kwe-IP kunye nendlela yokukhetha okulungileyoisidibanisi esingangeni manzikoomatshini bakho be-low-voltage.
Ukuqonda Imilinganiselo ye-IP
Imilinganiselo ye-IP ichazwa yi-International Electrotechnical Commission (IEC) kwaye inedijithi ezimbini. Idijithi yokuqala imele ukhuseleko kwizinto eziqinileyo (ezifana nothuli), ngelixa idijithi yesibini ibonisa ukukhuselwa kulwelo (njengamanzi). Umzekelo, ukulinganisa kwe-IP68 kuthetha ukuba isinxibelelanisi sikhuselwe ngokupheleleyo ekungeneni kothuli kwaye sinokumelana nokuntywiliselwa ixesha elide emanzini.
Imilinganiselo ye-IP eqhelekileyo kwiiNxulumanisi zeCable
• IP65: Olu luhlu lubonisa ukhuseleko ekungeneni kothuli kunye neejethi zamanzi. Iziqhagamshelo ezinolu kulinganisa zifanelekile ukuba zisetyenziswe ngaphandle apho zinokuvezwa yimvula okanye ukutshiza kwamanzi.
• IP67: Ezi ziqhagamshelo zikhuselwe eluthulini kwaye ziyakwazi ukumelana nokuntywiliselwa okwexeshana emanzini (ukuya kuthi ga kwimitha e-1 ngemizuzu engama-30). Zikulungele izicelo apho ukungena kwamanzi kuyinkxalabo.
• IP68: Eli lolona hlelo luphezulu lweziqhagamshelo ezingangeni manzi, olubonisa ukhuseleko eluthulini kunye nokuntywiliselwa emanzini okuqhubekayo. Iziqhagamshelo ezinomlinganiselo we-IP68 zilungele ukusetyenziswa kwamanzi okanye iindawo ezisingqongileyo ezinokuvezwa okubalulekileyo kwamanzi.
Ukukhetha iSidibanisi esiLungileyo esingangenwa ngamanzi
Xa ukhetha isidibanisi sentambo engenamanzi koomatshini bevoltage ephantsi, qwalasela ezi zinto zilandelayo:
• IiMeko zokusiNgqongileyo: Vavanya okusingqongileyo apho isiqhagamshelanisi siza kusetyenziswa. Ukuba isinxibelelanisi siya kuba sesichengeni samanzi, khetha i-IP ephezulu njenge IP67 okanye IP68.
• Umbane kunye nowangoku: Qinisekisa ukuba isiqhagamshelanisi sinikwe umlinganiselo wombane kunye neemfuno zangoku zesicelo sakho. Kumatshini we-low-voltage, izixhumi ezinomlinganiselo we-voltage ye-450V kunye nemilinganiselo yangoku ye-15A ukuya kwi-17.5A isetyenziswa ngokuqhelekileyo.
• Ukuhambelana kweCable: Khetha izihlanganisi ezihambelana neesayizi zentambo ozisebenzisayo. Umzekelo, izihlanganisi zinokuthatha iintambo eziqinileyo okanye eziguqukayo ukusuka kwi-0.5 mm² ukuya kwi-2.5 mm².
• Uhlobo loFakelo: Khetha phakathi kweziqhagamshelo ezingaphakathi kuqhagamshelo oluthe ngqo lwentambo ukuya kwintambo okanye iziqhagamshelo zephaneli yokunyuswa kwiiphaneli zesixhobo.
Imizekelo Eluncedo
Kumatshini ombane osezantsi kwiindawo ezingaphandle, isidibanisi esilinganiswe nge-IP67 sinokwanela. Ezi ziqhagamshelo ziyakwazi ukujongana nokuvezwa kwamanzi okwethutyana kwaye ziluthuli. Nangona kunjalo, ukuba isicelo sakho siquka utyhileko lwamanzi oluqhubekayo, olufana nofakelo lwangaphantsi kwamanzi, isidibanisi esikalwe nge-IP68 siyafuneka.
ULondolozo kunye noHlolo
Ukuqinisekisa ubude obude kunye nokuthembeka kweziqhagamshelo zakho zentambo ezingenamanzi, ukugcinwa rhoqo kunye nokuhlolwa kubalulekile. Khangela naziphi na iimpawu zokuguga, ukonakala, okanye ukuvuza. Faka endaweni yazo naziphi na izitywina ezonakalisiweyo okanye iziqhagamshelo ngokukhawuleza ukuze ugcine ukulinganisa kwe-IP kunye nokuthintela imiba yombane.
Ukuqukumbela
Ukuqonda iireyithingi ze-IP kubalulekile xa ukhetha izixhumi zentambo ezingangeni manzi koomatshini be-low-voltage. Ngokukhetha izixhumi ezinomlinganiselo ofanelekileyo we-IP, unokuqinisekisa ukuba iinkqubo zakho zombane zihlala zikhuselekile kuthuli kunye nokungena kwamanzi. Qwalasela iimeko zokusingqongileyo, i-voltage kunye neemfuno zangoku, ukuhambelana kwentambo, kunye nohlobo lofakelo xa ukhetha izihlanganisi zakho. Ngokhetho olufanelekileyo, unokwandisa ukuthembeka kunye nokhuseleko lofakelo lwakho lombane.
