Yintoni intambo yentambo

I-cable intermediate joint sisixhobo esidibanisa ikhebula kunye nebhokisi le-junction, kwaye isetyenziselwa ukudibanisa i-core cable okanye i-sheath, i-insulation kunye ne-sheath komnye nomnye.Kwizicelo zesistim yamandla, inani loqhagamshelo oluphakathi liphezulu.Amalungu aphakathi aqhelekileyo anohlobo oluthe tye (oluqhelekileyo olubizwa ngokuba yi "straight-through") kunye ne-bend-through type.

Iimpawu zodidi oluthe ngqo zezi:
(1) Isakhiwo esilula, ubungakanani obuncinci kunye nobunzima obulula;

(2) Ulwakhiwo lufanelekile, kwaye lunokusebenza ngaphandle kokukhulula i-sheath yangaphandle yekhebula ngexesha lofakelo;

(3) Ixabiso liphantsi, kodwa ilahleko yomgca emva kokubeka inkulu.

Iimpawu zohlobo olugobileyo zezi:
(1) Ulwakhiwo luntsonkothe ​​ngakumbi;

(2) Ilahleko yomgca eyenziwe emva kokubeka incinci kunohlobo oluchanekileyo;

(3) Ulwakhiwo luyingxaki kancinane;

(4) Ixabiso liphezulu kancinane.

Kubunjineli obusebenzayo, indlela yokuxhathisa ye-DC isetyenziswa ngokubanzi ukubona ukusebenza kwe- through.Umgaqo wendlela ye-DC yokuxhathisa kukuba xa i-voltage ye-DC isetyenziswa kwii-electrode ezimbini zokudlula, ixabiso lokumelana lihambelana ngokungafaniyo kwisikwere sombane osetyenzisiweyo.

Ngoko ke, ukuba nje ubungakanani bokuchasana kwe-DC bulinganiswa, i-conductivity ye-pass-pass inokwaziwa.Iindlela zokulinganisa ukuxhathisa kwe-DC zohlulwe zibe ziindidi ezimbini: indlela ethe ngqo kunye nendlela engathanga ngqo:
Indlela ethe ngqo kukulinganisa ngokuthe ngqo ukuhla kombane we-DC phakathi kwee-electrode ezimbini kunye ne-multimeter ukumisela okulungileyo kunye nokubi kwe-straight-through.

Indlela engathanga ngqo kukugweba ukuba ifanelekile na okanye hayi ngokulinganisa umsinga otshintshayo phakathi kwee-electrode ezimbini, ezibizwa ngokuba yi-AC impedance method okanye i-frequency power resistant test method.Indlela yokuvavanya amandla ombane yenye yeendlela eziqhelekileyo nezisebenzayo zokugweba ukuba icandelo elithile le-conductor lifanelekile na okanye hayi..

Xa amandla ombane wefrikhwensi yexabiso elichaziweyo (ngokuqhelekileyo i-50hz) isetyenziswa kuzo zombini iziphelo zomqhubi ovavanyiweyo, jonga ukuba ingaba imveliso evavanyiweyo inento yokuphuka.Ayisebenzi kweli candelo locingo.
