Izinto zikagesi ezingaqhumi zingaqhumi zimbozekile izingxenye ezingase zikhiqize izinhlansi, ama-arcs, kanye namazinga okushisa ayingozi endaweni ebiyelwe okuvikela ukuqhuma. Lokhu kuboshwa kulawula ukuqhuma ngaphakathi, ukuyivimbela ekuthungeleni amagesi avuthayo nothuli. Indawo ebiyelwe engashi kufanele ibe namandla anele okusebenza ukuze imelane nokuqhuma kwangaphakathi ngaphandle kokulimala. Igebe lokuqhuma liklanyelwe ukupholisa amalangabi, yehlisa kancane ijubane ilangabi ukusabalalisa, bese uphazamisa iketango lokusheshisa, ukuvimbela ukuvutha kwangaphandle ezindaweni eziqhumayo.
Uhlobo Lokuphepha Olunyusiwe
Ukwenyuka kwamathuluzi kagesi angaqhumi igxile ekuthuthukiseni ukuphepha kukagesi kwangaphakathi ngokusebenzisa imishini, kagesi, kanye nezinyathelo zokuvikela ukushisa ukuze kuvinjelwe ukuvutha igesi evuthayo izindawo. Izinto ezisezingeni eliphezulu zokuvikela zisetshenziselwa ukunciphisa ukumelana nokuxhumana, ngaleyo ndlela ehlisa amazinga okushisa. Izinga lokuvikela liphakeme (hhayi ngaphansi kwe-IP54). Ngokuvamile, lolu hlobo luhlanganisa izintambo namatheminali kodwa alufaki amabhokisi ahlanganisa ukuqhuma, transformers zamanje, noma ezinye izingxenye zikagesi.
Uhlobo Lokuphepha lwangaphakathi
Ukufeza izinhloso zokuvikela ukuqhuma, uhlobo lokuphepha lwangaphakathi isebenzisa umkhawulo wamandla kumasekhethi. Imingcele kagesi, njenge-voltage, okwamanje, inductance, kanye nekhono, kufanele ihlangabezane nezidingo zokuvikela ukuqhuma. Ngisho nasezimeni zama-circuits amafushane, ukwephulwa kwe-insulation, noma amanye amaphutha aholela ekukhishweni kukagesi kanye nemiphumela yokushisa, ngeke ivuthe eziqhumayo umoya wegesi. Le nqubo iwela ngaphansi ‘komandla aphansi’ isigaba sobuchwepheshe, okubonisa umkhawulo kagesi kanye namandla ashisayo anamandla aphansi aphumayo. Amadivayisi awakwazi ukukhiqiza noma yiziphi izinhlansi ezingaba yingozi.
