1.Izizathu zokuguga zeengcingo kunye neentambo: umonakalo wangaphandle.Ngokohlalutyo lomsebenzi kwiminyaka yakutshanje, iimpazamo ezininzi zentambo zibangelwa ngumonakalo owenziwe ngoomatshini.Ngokomzekelo: ucingo kunye nofakelo lwentambo alukho ulwakhiwo oluqhelekileyo, kulula ukwenza umonakalo ngoomatshini. ;Kukwalula ukonakalisa iingcingo kunye neentambo ezisebenza ngexesha lolwakhiwo lwasekuhlaleni kwiingcingo ezingcwatyelwe ngokuthe ngqo kunye neentambo.Ngamanye amaxesha, ukuba umonakalo awubi kakhulu, kuya kuthatha iinyanga ezininzi okanye iminyaka ukwenza ukuba inxalenye eyonakeleyo iphuke ngokupheleleyo kwaye yenze. impazamo.Ngamanye amaxesha, umonakalo unzima kwaye i-short-circuit fault ingenzeka, ichaphazela ngokuthe ngqo ukuveliswa okukhuselekileyo kweyunithi yamandla.
2.Izizathu ezigugayo zeengcingo kunye neentambo: ukugqunyelelwa okumanzi.Kuxhaphake kakhulu kwaye kwenzeka ekupheleni kweengcingo kunye neentambo ezingcwatywa ngokuthe ngqo okanye kwidrain.Umzekelo: iintambo zentambo ezenziwe ngokungafanelekanga kwaye kwiimeko zemozulu ezifumileyo ukwenza umdibaniso, uya kwenza amanzi adibeneyo okanye axutywe kunye nomphunga wamanzi, ixesha elide phantsi kwesenzo sentsimi yombane ukwenza amasebe amanzi, ngokuthe ngcembe awonakalisa amandla okufakelwa kwentambo ebangelwa yimpazamo.
3. Ukuguga okubangela iingcingo kunye neentambo: ukubola kweekhemikhali.Ukuba iintambo zingcwatywe ngokuthe ngqo kwindawo ene-asidi kunye nefuthe le-alkali, i-armored, i-lead okanye yangaphandle yokukhusela i-cables iya kudla i-corrod.Umaleko okhuselayo uya kubandezeleka kwi-chemical corrosion okanye i-electrolytic corrosion ixesha elide, okubangela ukungaphumeleli komgangatho okhuselayo kunye nokunciphisa ukufakwa kwe-insulation, okuya kukhokelela ekungaphumeleli kweengcingo kunye neentambo. kakhulu.
I-4.Izizathu zokuguga zocingo kunye nekhebula: ukusebenza kwexesha elide lomthwalo ogqithisiweyo.Ukusebenza ngokugqithisileyo, ngenxa yempembelelo ye-thermal yangoku, umqhubi uya kutshisa ngokuqinisekileyo xa umthwalo wangoku udlula kwikhebula.Okwangoku, umphumo wesikhumba wentlawulo, ilahleko yangoku ye-eddy yezixhobo zentsimbi kunye nelahleko ephakathi kwe-insulation iya kuvelisa ubushushu obongezelelweyo, obuya kwandisa ubushushu bocingo kunye nentambo. ukuguga kwe-insulation kunye nokuba i-insulation iya kuchithwa.Ngokukodwa ehlotyeni elitshisayo, ukunyuka kweqondo lokushisa kwekhebula kudla ngokukhokelela ekuqhekekeni kokuqala kobuthathaka be-cable insulation, ngoko ehlotyeni, iimpazamo zekhebula zivame kakhulu.
I-5.Izizathu zokuguga zocingo kunye nekhebula: i-cable joint failure.I-cable joint ikhonkco elibuthathaka kakhulu kumgca wentambo.Isiphoso somdibaniso wentambo obangelwa yimpazamo ngqo yabasebenzi (ulwakhiwo olubi) luhlala lusenzeka.Kwinkqubo yokwenza ucingo kunye nentambo yokudibanisa, ukuba umdibaniso awucinezeleki ngokuqinileyo kwaye ukufudumeza akwanele, inethiwekhi yokuqala iya kukhokelela ukuncipha kwe-insulation yentloko yentambo, ngaloo ndlela kubangele ingozi.
6. Iimbangela zokuguga zeengcingo kunye neentambo: indawo kunye neqondo lokushisa.Indawo yangaphandle kunye nomthombo wokushisa apho intambo ifakwe khona iya kubangela ukuba ukushisa kwentambo kuphakame kakhulu, ukuchithwa kwe-insulation, kunye nokuqhuma kunye nomlilo.
