Ikhebula le-Jiapu likutshela izimbangela ezivamile zezinkinga zekhebula lamandla.Izinhlobo zamaphutha ekhebula zingahlukaniswa zibe isisekelo, isifunda esifushane, ukunqanyulwa kwezigaba ezintathu eziyinhloko zezinhlobo zamaphutha zimi kanje:
Isigaba sentambo ewumgogodla ephukile noma yocingo olunezigaba eziningi
Esivivinyweni sokuxhunywa komqhubi wekhebula, ukumelana nokufakwa kwe-cable conductor kanye nezinhlinzeko ezifanele zomugqa, kodwa ngokubuka kwesigaba noma izigaba eziningi azikwazi ukuxhunywa, khona-ke isigaba sokuphulwa kocingo okuyisisekelo noma ukuhlukana kwezigaba eziningi.
Ikhebula elingumgogodla owodwa noma amabili isisekelo esiyisisekelo
Ingqikithi yamakhebula amathathu-core noma amakhondaktha amabili ayinhloko anokuhlolwa kwethebula elinyakazisayo lokunyakazisa ngaphandle koxhumo, bese kuba ingqikithi noma okubili komgogodla wokumelana ne-telemetry yokumelana nokufakwa emhlabathini.Uma umongo kanye nomgogodla phakathi kokuba khona kokumelana nokufakwa kwe-insulation kunevelu evamile liphansi kakhulu kunevelu yaleli nani le-insulation resistance value lingaphezu kuka-1000 ohms libizwa ngokuthi iphutha eliphezulu le-grounding resistance;Ngokuphambene, iphutha eliphansi lokumelana nesisekelo.Womabili la maphutha abizwa ngokuthi amaphutha anqanyuliwe futhi asekelwe phansi.
Isifunda esifushane esinezigaba ezintathu
Usayizi wokumelana nesisekelo somjikelezo omfishane yikhebula lokuhlonza iphutha lesisekelo lesigaba esifushane lesigaba sesithathu.Kunezinhlobo ezimbili zephutha le-short-circuit: iphutha le-short-circuit eliphikisayo, iphutha le-short-circuit eliphikisayo.Lapho i-short-circuit yesigaba sesithathu, ingaphansi kuka-1000 ohms yokumelana nomhlabathi iphutha eliphansi le-short-circuit, ngokuphambene nalokho, iphutha eliphezulu le-short-circuit.
Ukuhlaziya imbangela:
Okokuqala: umonakalo wangaphandle
Izinkinga zekhebula emonakalweni wangaphandle ziyimbangela evame kakhulu yenkinga.Ikhebula lonakaliswa amandla angaphandle esikhathini esizayo sizobonisa indawo enkulu yokuhluleka kwamandla.Isibonelo, inqubo yokwakhiwa kwamapayipi angaphansi komhlaba, ikhebula ngoba ukudonsa komshini wokwakha kukhulu kakhulu futhi kwakhishwa;ukufakwa kwekhebula, ungqimba oluvikelayo ngenxa yokugoba ngokweqile kwekhebula nokulimala;ikhebula elisikiwe liyaxebuka ukusika ngokweqile kanye nezimpawu zommese zijule kakhulu.Lezi zakhi zangaphandle eziqondile zizodala umonakalo othile kukhebula.
Okwesibili: umswakama wokushisa
Inqubo yokukhiqiza ikhebula ayicwengisisiwe izoholela ekuqhekekeni kongqimba lwekhebula lokuvikela;Ukuvalwa kwe-cable terminal joints akukona;umkhono wokuvikela ikhebula ekhebulani elisetshenziswe into ebhoboziwe noma okungenzeka ukuthi yagqwala.Lezi yizizathu eziyinhloko zomswakama we-cable insulation.Okwamanje, ukumelana nokufakwa kwe-insulation kwehla, ukwanda kwamanje, kubangela izinkinga zamandla.
Ezintathu: ukugqwala kwamakhemikhali
Isenzo samanje sesikhathi eside sizovumela ukufakwa kwekhebula kwenzeke ukushisa okukhulu.Uma ukufakwa kwekhebula kusebenza isikhathi eside endaweni empofu yamakhemikhali kuzoshintsha izakhiwo zayo ezibonakalayo, ukuze ukuguga kwekhebula lokuguga ngisho nokulahlekelwa umphumela, izinkinga zamandla zizokwenzeka.
Okwesine: ukusebenza kokugcwala ngokweqile kwesikhathi eside
Ikhebula lisebenza isikhathi eside endaweni ezungezile, uma ungqimba lokufakwa komugqa lunokungcola noma ukuguga, kuhambisana nezici zangaphandle ezinjengombani nokunye okungaphezu kwamandla kagesi, ukulayishwa ngokweqile kwenzeka ukushisa okukhulu, kulula kakhulu ukwethula izinkinga zekhebula. .
