Ukukhethwa kwezinto zikagesi ebhokisini likagesi kufanele ziguqulwe kabusha kwizinsiza zokujikeleza kanye nezinto zikagesi. Ukufakwa kwebhokisi likagesi kuqondile futhi kuqinile, futhi kukhona indawo yokusebenza ezungeze. Awekho amanzi amile noma ama-sundries emhlabathini, futhi akukho mthombo wokushisa nokudlidliza eduzane. Ibhokisi likagesi kufanele libe nobufakazi bemvula nobufakazi bothuli. Ibhokisi lokushintsha akufanele lingabi ngaphezu kwe-3m kude nemishini ehleliwe ukuze ilawulwe.
16. Kungani usebenzise ukuvikelwa okulinganisiwe?
Impendulo: Ngoba ukuhanjiswa kwamandla kagesi okuphansi kanye nokusatshalaliswa ngokuvamile sebenzisa ukusatshalaliswa kwamandla ahleliwe. Uma umvikeli ovuzayo efakwe kuphela ekugcineni komugqa (ebhokisini lokushintsha), yize ulayini onephutha unganqanyulwa lapho kuvuza ukuvuza, uhla lokuvikela luncane; Ngokufanayo, ukube nje umugqa we-trunk trust (ebhokisini lokusabalalisa) noma umugqa wesiqu (ibhokisi eliphambili lokusabalalisa) ufakiwe Faka umvikeli ovuzayo, noma ngabe lonke uhlelo lokuvikela lungasho lutho, kepha luzokwenza lonke uhlelo lokuthola amandla okusebenza okujwayelekile, kodwa futhi lukwenza kube yinto ukuphathwa ngengozi. Ngokusobala, lezi zindlela zokuvikela azanele. indawo. Ngakho-ke, izidingo ezihlukile ezinjengomugqa nokulayisha kufanele zixhunywe, kanye nabavikeli ngezimpawu ezahlukahlukene zokuvuza kufanele zifakwe kumugqa omkhulu we-voltage voltage Endabeni yokuvikelwa okubaliwe, amabanga okuvikelwa akhethiwe kuwo wonke amazinga kufanele asebenzisane ukuze aqinisekise ukuthi umvikeli ovuzayo ngeke aqede isenzo lapho ingozi yokuvuza noma ingozi yomuntu siqu yenzeka ekugcineni; Ngasikhathi sinye, kuyadingeka ukuthi lapho uMvikeli Osezingeni Eliphansi ehluleka, uMvikeli ophezulu azosebenza ukulungisa umvikeli ophansi. Ukwehluleka ngengozi. Ukuqaliswa kokuvikelwa okubalwe kunika amandla imishini ngayinye kagesi ukuba ibe namazinga angaphezu kwamabili ezinyathelo zokuvikela ukuvuza, okungagcini nje kuphela ngezimo eziphephile zemishini kagesi ekugcineni kwegridi yogesi ephansi, kepha futhi ihlinzeka ngokuxhumana okuningi okuqondile nokungaqondile kokuphepha komuntu siqu. Ngaphezu kwalokho, kunganciphisa umkhawulo wokuphuma kwamandla lapho kwenzeka iphutha, futhi kulula ukuthola futhi uthole iphuzu elilungile ekuthuthukiseni izinga lokusetshenziswa kukagesi okuphephile, kanye nokuqinisekisa ukuphepha okusebenzayo.
