Intambo yeJiapu ikuxelela izizathu eziqhelekileyo zeengxaki zentambo yamandla.Iintlobo zeempazamo zekhebula zinokwahlulwa ngokwesiseko, isekethe emfutshane, ukuqhawulwa kwezi ndidi zintathu eziphambili zeentlobo zeempazamo zezi zilandelayo:
Isigaba socingo olungundoqo olwaphukileyo okanye olunezigaba ezininzi
Kwi-experiment ye-cable conductor connection, i-cable conductor insulation resistance kunye nemimiselo echaphazelekayo yomgca, kodwa kwimbono yesigaba okanye izigaba ezininzi azikwazi ukudibaniswa, ngoko ke isigaba se-core break break okanye ezininzi zesigaba.
Iintambo ezintathu ezingundoqo enye okanye ezimbini ezisisiseko
Undoqo wentambo ezintathu okanye ezimbini ezingundoqo kunye novavanyo lwetafile eshukumayo eshukumayo ngaphandle koqhagamshelo, kwaye emva koko ingundoqo okanye ezimbini ezingundoqo kwi-telemetry yokumelana nokugquma komhlaba.Ukuba undoqo kunye nondoqo phakathi kobukho bokuxhathisa ukugquma kunexabiso eliqhelekileyo lingaphantsi kakhulu kunexabiso lexabiso lokumelana nokugquma liphezulu kune-1000 ohms libizwa ngokuba yi-high resistance grounding fault;Ngokuchaseneyo, yimpazamo esezantsi yokuxhathisa.Zombini ezi mpazamo zibhekiswa kuzo njengeziphoso eziqhawulwe kunye nezisekelwe phantsi.
Isigaba sesithathu sesekethe emfutshane engundoqo
Ubungakanani bokumelana nomgangatho omfutshane wesekethe yintambo yenqanaba lesithathu lesiseko sochongo lwempazamo yesiseko.Kukho iintlobo ezimbini zempazamo yesekethe emfutshane: impazamo ephantsi yesekethe, impazamo ephezulu yesekethe.Xa inqanaba lesithathu i-core short-circuit, ngaphantsi kwe-1000 ohms yokumelana nomhlaba yimpazamo ephantsi yokumelana ne-short-circuit, ngokuchaseneyo, i-high resistance ye-short-circuit fault.
Uhlalutyo lwesizathu:
Okokuqala: umonakalo wangaphandle
Iingxaki zekhebula kumonakalo wangaphandle yimbangela eqhelekileyo yengxaki.Intambo yonakaliswe yimikhosi yangaphandle kwixesha elizayo iya kubonisa indawo enkulu yokungaphumeleli kwamandla.Umzekelo, inkqubo yokwakhiwa kwemibhobho engaphantsi komhlaba, intambo ngenxa yokuba intambo yoomatshini bokwakha inkulu kakhulu kwaye yatsalwa;i-cable insulation, i-shielding layer ngenxa yokugoba ngokugqithiseleyo kwentambo kunye nomonakalo;intambo isike ukuxobula ukusika kakhulu kwaye imela iphawula nzulu kakhulu.Ezi zinto zangaphandle ezithe ngqo ziya kwenza umonakalo othile kwikhebula.
Okwesibini: ukufuma kwe-insulation
Inkqubo yokuvelisa ikhebula ayicocwanga iya kukhokelela kuluhlu olukhuselayo lwentambo;Ukutywinwa kwe-cable terminal joints ayikho;Umkhono wokukhusela intambo kwintambo esetyenziswe yinto egqojoziweyo okanye mhlawumbi ifumene umhlwa.Ezi zizathu eziphambili zokufuma kwe-cable insulation.Okwangoku, ukuchasana kwe-insulation kuyancipha, ukunyuka kwangoku, kubangela iingxaki zamandla.
Ezintathu: ukubola kweekhemikhali
Isenzo sexesha elide langoku siya kuvumela ukugquma kwentambo kwenzeke ubushushu obuninzi.Ukuba i-cable insulation isebenze ixesha elide kwindawo engafanelekanga yeekhemikhali iya kutshintsha iimpawu zayo ezibonakalayo, ukwenzela ukuba i-cable insulation iguga kwaye ide ilahlekelwe yimpembelelo, iingxaki zamandla ziya kwenzeka.
Isine: ukusebenza kokugqithiswa kwexesha elide
Ikheyibhuli yexesha elide yokusebenza okuphezulu kwangoku kokusingqongileyo, ukuba umaleko wokugquma umgca unokungcola okanye ukwaluphala, udityaniswa nezinto zangaphandle ezinjengombane kunye nezinye iimpembelelo zamandla ombane, ukulayisha ngaphezulu kwenzeka ubushushu obuninzi, kulula kakhulu ukubonisa iingxaki zentambo. .
