Power cable chinokonzera dambudziko rekuongorora

Jiapu tambo inokuudza izvo zvinowanzoitika zvemagetsi tambo matambudziko.Cable kukanganisa mhando dzinogona kukamurwa kuita pasi, pfupi dunhu, kudimburwa kweatatu makuru mapoka emhando dzekukanganisa ndeaya anotevera:
Chikamu chewaya yepakati yakatsemuka kana kuwanda kwewaya yakatyoka
Mune tambo conductor yekubatanidza kuyedza, iyo tambo conductor insulation kuramba uye izvo zvinoenderana neiyo mutsara, asi mukuona kwechikamu kana akawanda nhanho haigone kubatanidzwa, ipapo chikamu chepakati waya yekupwanya kana akawanda chikamu chinoputika.
Three-core tambo imwe kana maviri musimboti grounding
Matatu-musimboti tambo yepakati kana maviri epakati conductor ane insulation achizunguza tafura bvunzo kunze kwekubatanidza, uyezve musimboti kana maviri musimboti kune pasi insulation kuramba telemetry.Kana iyo musimboti uye musimboti pakati pekuvapo kwekupokana kwekupokana pane yakajairika kukosha kwakadzikira zvakanyanya kupfuura kukosha kweiyo insulation yekudzivirira kukosha kwakakwira kupfuura 1000 ohms kunonzi kupikisa kwepasi pasi;Sezvineiwo, yakaderera kuramba grounding kukanganisa.Zvose zvinokanganisa izvi zvinonzi zvakadimburwa uye zvakadzika zvikanganiso.
Three-phase core short circuit
Short-circuit grounding resistance size ndiyo tambo yetatu-phase core short-circuit fault identification yehwaro.Kune marudzi maviri echikanganiso chepfupi-yedunhu: kushomeka kwekushomeka kwepfupi-yedunhu kukanganisa, kupikisa kwakanyanya kupfupi-dunhu kukanganisa.Kana iyo yechitatu-chikamu core pfupi-circuit, isingasviki 1000 ohms yekupokana kwepasi yakaderera kushomeka kwepfupi-yedunhu kukanganisa, pane zvinopesana, ndeyekupikisa kwakanyanya kupfupi-dunhu kukanganisa.

Kuongorora kwechikonzero:
Kutanga: kukuvara kwekunze
Matambudziko etambo mukukuvara kwekunze ndiyo inonyanya kukonzera dambudziko.Iyo tambo yakakuvadzwa nemasimba ekunze mune ramangwana icharatidza nzvimbo yakakura yekutadza simba.Semuyenzaniso, yepasi pevhu kuvakwa kwepombi, tambo nekuti mushini wekuvaka wekudhonza wakakurisa uye wakadhonzwa;cable insulation, shielding layer nekuda kwekunyanya kukotama kwetambo uye kukuvara;cable cut ichipepeta kucheka zvakanyanya uye mavanga ebanga akadzika zvakanyanya.Izvi zvakananga zvekunze zvinhu zvinogadzira kumwe kukuvadza kune tambo.
Chechipiri: insulation unyoro
Cable yekugadzira maitiro haina kunatswa inotungamira kune tambo yekudzivirira layer yakatsemuka;cable terminal joints sealing haisi;Cable protection sleeve mutambo inoshandiswa nechinhu chakaboorwa kana kuti chakaita ngura.Izvi ndizvo zvikonzero zvikuru zveiyo cable insulation unyoro.Parizvino, kudzivirira kwekudzivirira kunodonha, kuwedzera kwezvino, kukonzera matambudziko emagetsi.
Chetatu: kemikari ngura
Yenguva yakareba ikozvino chiito chinobvumira iyo cable insulation inoitika yakawanda kupisa.Kana iyo tambo yekuvharisa ichishanda kwenguva yakareba munzvimbo yakashata yemakemikari ichachinja maitiro ayo emuviri, kuitira kuti tambo yekuvharisa kuchembera uye kunyange kurasikirwa nemhedzisiro, matambudziko emagetsi achaitika.
Zvina: kushanda kwenguva yakareba kuwandisa
Cable yenguva refu-yazvino kushanda munharaunda, kana mutsara wekudzivirira mutsara uine tsvina kana kuchembera, pamwe chete nezvinhu zvekunze zvakaita semheni uye zvimwe pamusoro pesimba remagetsi, kuwandisa kunoitika kupisa kwakawanda, zviri nyore kwazvo kuunza matambudziko etambo. .
