Jiapu cable e u bolella lisosa tse tloaelehileng tsa mathata a lithapo tsa motlakase.Mefuta ea phoso ea lithapo e ka aroloa ka mokhoa oa motheo, potoloho e khuts'oane, ho khaoha ha mekhahlelo e meraro ea mefuta ea liphoso ke tse latelang:
Karolo ea terata ea mantlha e robehileng kapa e robehileng ka mekhahlelo e mengata
Tekong ea khokahanyo ea li-cable conductor, khanyetso ea li-cable conductor insulation le lipehelo tse amehang tsa mohala, empa ka pono ea mokhahlelo kapa mekhahlelo e mengata e ke ke ea kopanngoa, ebe karolo ea khefu ea terata ea mantlha kapa likheo tse ngata tsa mekhahlelo.
Tharo-core thapo e le 'ngoe kapa tse peli tsa mantlha tsa motheo
Li-cable core tse tharo kapa li-conductor tse peli tsa mantlha tse nang le tlhahlobo ea tafole e sisinyehang ka ntle ho khokahanyo, ebe li-cores kapa tse peli tsa mantlha ho ea ho li-insulation resistance resistance telemetry.Haeba konokono le motheo pakeng tsa boteng ba ho hanyetsa ho hanyetsa ho feta boleng bo tloaelehileng bo le tlase haholo ho feta boleng ba boleng ba ho hanyetsa ho hanyetsa bo phahameng ho feta 1000 ohms e bitsoa phoso e phahameng ea ho hanyetsa fatše;Ka lehlakoreng le leng, ke phoso e fokolang ea motheo ea ho hanyetsa.Liphoso tsena ka bobeli li bitsoa liphoso tse khaotsoeng le tse thehiloeng.
Potoloho e khutšoanyane ea mekhahlelo e meraro
Short-circuit grounding resistance size ke thapo ya thapo ya motheo wa mekgahlelo e meraro e kgutshwane ya pontsho ya motheo.Ho na le mefuta e 'meli ea phoso ea potoloho e khuts'oane: phoso e tlase ea potoloho e khuts'oane, phoso e phahameng ea nako e khuts'oane.Ha mekhahlelo e meraro ea mantlha e khuts'oane, e ka tlase ho 1000 ohms ea ho hanyetsa fatše ke phoso e tlase ea potoloho e khuts'oane, ho fapana le hoo, ke phoso e phahameng ea potoloho e khuts'oane.
Tlhahlobo ea sesosa:
Ea pele: tšenyo e ka ntle
Mathata a cable ka tšenyo e ka ntle ke sesosa se tloaelehileng sa bothata.Cable e senyehile ke matla a ka ntle nakong e tlang e tla bontša sebaka se seholo sa ho hlōleha ha matla.Mohlala, ts'ebetso ea kaho ea liphaephe tse ka tlas'a lefatše, thapo hobane mochini oa kaho o hohelang o moholo haholo mme o ile oa ntšoa;ho kenya mohala, lera le sireletsang ka lebaka la ho kobeha ho feteletseng ha mohala le tšenyo;cable cut ho ebola ho seha hofeta tekanyo le matshwao a thipa a tebile haholo.Lintho tsena tse tobileng tse ka ntle li tla etsa tšenyo e itseng ho cable.
Ea bobeli: mongobo oa insulation
Ts'ebetso ea ho etsa li-cable ha e hloekisoe e tla lebisa ho lera le sireletsang la cable le robehileng;ho tiisoa ha cable terminal manonyeletso ha ho joalo;thapo e sirelelitsoeng ka thapo e sebelisoang ke ntho e hlabiloeng kapa mohlomong e holile.Tsena ke mabaka a ka sehloohong a mongobo oa cable insulation.Hona joale, ho hanyetsa ho thibela ho theoha ho theoha, ho eketseha ha hona joale, ho baka mathata a matla.
Tse tharo: ho bola ha lik'hemik'hale
Ketso ea nako e telele ea hona joale e tla lumella hore ho kenngoa ha cable ho be le mocheso o mongata.Haeba kabel insulation sebetsa ka nako e telele tikolohong e futsanehileng lik'hemik'hale tla fetola thepa ea eona ea 'mele, e le hore kabel insulation botsofali esita le ho lahleheloa ke phello, mathata a matla a tla etsahala.
Tse 'nè: ts'ebetso ea nako e telele ea overload
Cable ea nako e telele ea ts'ebetso ea nako e telele tikolohong, haeba lera la ho kenya mohala le na le litšila kapa botsofali, hammoho le lintlha tse ka ntle tse kang lehalima le tse ling tse fetang matla a motlakase, ho kenya mocheso o mongata haholo, ho bonolo haholo ho hlahisa mathata a cable. .
