Ikhebula le-Jiapu likutshela izimbangela ezivamile zezinkinga zekhebula likagesi. Izinhlobo zamaphutha ekhebula zingahlukaniswa zibe yi-grounding, short circuit, kanye nokunqanyulwa kwezigaba ezintathu eziyinhloko zezinhlobo zamaphutha yilezi ezilandelayo:
Isigaba sentambo eyinhloko ephukile noma intambo ephukile enezigaba eziningi
Ekuhlolweni kokuxhumeka komqhubi wekhebula, ukumelana kokufakwa kokushisa komqhubi wekhebula kanye nezinhlinzeko ezifanele zomugqa, kodwa uma kubhekwa isigaba noma izigaba eziningi azikwazi ukuxhunywa, bese kuba isigaba sokuphuka kwentambo eyinhloko noma ukuphuka kwesigaba okuningi.
Ikhebula eliyinhloko ezintathu eliyisisekelo esisodwa noma ezimbili
Ama-core core ekhebula anezinsika ezintathu noma ama-core conductor amabili anetafula lokuthuthumela i-insulation avivinywa ngaphandle kokuxhumeka, bese kuba yi-core noma ezimbili ezinsika i-ground insulation resistance telemetry. Uma i-core kanye ne-core phakathi kokuba khona kokumelana ne-insulation kunenani elijwayelekile liphansi kakhulu kunenani lale nombolo yokumelana ne-insulation iphakeme kune-1000 ohms ibizwa ngokuthi i-grounding fault ephezulu; Ngokuphambene nalokho, i-grounding fault ephansi. Womabili la maphutha abizwa ngokuthi amaphutha angaxhunyiwe kanye namaphutha asekelwe.
Isekethe emfushane ye-core yesigaba esithathu
Usayizi wokumelana nokugqwala kwesekethe esifushane yikhebula lokuhlonza iphutha lesekethe esifushane sesigaba sesithathu sesisekelo. Kunezinhlobo ezimbili zephutha lesekethe esifushane: iphutha lesekethe esifushane elinokumelana okuphansi, iphutha lesekethe esifushane elinokumelana okuphezulu. Lapho isekethe esifushane sesigaba sesithathu, ngaphansi kwama-ohm ayi-1000 ohms okumelana nomhlabathi kuyiphutha lesekethe esifushane elinokumelana okuphansi, ngokuphambene nalokho, kuyiphutha lesekethe esifushane elinokumelana okuphezulu.
Ukuhlaziywa kwembangela:
Okokuqala: umonakalo wangaphandle
Izinkinga zekhebula emonakalweni wangaphandle yimbangela evame kakhulu yenkinga. Ikhebula lonakaliswe amandla angaphandle esikhathini esizayo lizobonisa indawo enkulu yokwehluleka kwamandla. Isibonelo, inqubo yokwakha ipayipi elingaphansi komhlaba, ikhebula ngoba ukudonsa komshini wokwakha kukhulu kakhulu futhi kwakhishwa; ukuvala ikhebula, ungqimba lokuvikela ngenxa yokugoba ngokweqile kwekhebula kanye nomonakalo; ukusika ikhebula ukuxebuka ukusika ngokweqile kanye namamaki ommese ajule kakhulu. Lezi zinto zangaphandle eziqondile zizokwenza umonakalo othile kukhebula.
Okwesibili: umswakama wokushisa
Inqubo yokukhiqiza ikhebula engalungiswanga izoholela ekutheni ungqimba lokuvikela lwekhebula luqhekeke; ukuvalwa kwamalunga ekhebula akuqhekeki; isivikelo sekhebula esisekhebulani esisetshenziswe yinto ebhoboziwe noma mhlawumbe sibhobozekile. Lezi yizizathu eziyinhloko zomswakama wokufakwa kwekhebula. Okwamanje, ukumelana kokufakwa kwekhebula kuyehla, ugesi uyakhuphuka, okubangela izinkinga zamandla.
Okwesithathu: ukugqwala kwamakhemikhali
Isenzo samanje sesikhathi eside sizovumela ukuthi ukufakwa kwekhebula kungene ekushiseni okuningi. Uma ukufakwa kwekhebula kusebenza isikhathi eside endaweni engcolile yamakhemikhali kuzoshintsha izakhiwo zalo zomzimba, ukuze ukufakwa kwekhebula kukhule futhi kulahlekelwe ngisho nokusebenza, kuzovela izinkinga zamandla.
Okwesine: ukusebenza ngokweqile kwesikhathi eside
Ukusebenza kwekhebula isikhathi eside ngesikhathi sokushisa okuphezulu endaweni ezungezile, uma ungqimba lokufakwa komshini wokushisa lunokungcola noma ukuguga, kuhlanganiswe nezici zangaphandle njengombani kanye nokunye umthelela we-voltage engaphezu kwamandla kagesi, ukulayisha ngokweqile kwenzeka ukushisa okuningi, kulula kakhulu ukuletha izinkinga zekhebula.
