1. Iyini ikhebula lamanzi?
Amakhebuli angasetshenziswa ngokujwayelekile emanzini abizwa ngokuthi amakhebule angamelana namanzi (materproof). Lapho ikhebula libekwe ngaphansi kwamanzi, livame ukugxila ezindaweni zamanzi noma ezindaweni ezimanzi, ikhebula liyadingeka ukuba nomsebenzi wokuvimbela amanzi (ukumelana), okudingeka ukuthi ube nomsebenzi wokucwilisa amanzi, futhi uqinisekise ukulimala kwentambo, futhi kuqinisekiswe ukusebenza kwesikhathi eside kwentambo ngaphansi kwamanzi. Imodeli yekhebula elivame ukusetshenziswa kwamanzi yi-JHS, okungokwekhebula le-Rubber Sleeve Waterproof Cable, ikhebula lamanzi lihlukaniswe ngentambo yamandla angangenzi manzi nekhebula lekhompyutha elingavunyelwe, njll.
2. Uhlobo lwesakhiwo sekhebula lamanzi
(1). Okwezintambo eziyinhloko eyodwa, bophaI-Semi-Rightive Wokuvimba Amanziesihlangu sokufakelwa, bopha okujwayelekileitheyiphu yokuvimba amanziNgaphandle, bese ucwilisa i-sheath yangaphandle, ukuze uqinisekise ukuthintana okugcwele kwesihlangu sensimbi, kusonga kuphela itheyiphu yokuvinjwa kwamanzi ngaphandle kwesihlangu sokufaka amanzi, ukugcwaliswa kungagcwaliswe i-filler ejwayelekile noma i-filler ye-water block. Izinsimbi zangaphakathi nezinto zokwenziwa zangaphandle ze-sheath ziyefana nalezo ezichazwe kwikhebula elilodwa eliyinhloko.
(2). Isendlalelo se-Aluminium eluhlaza esihlanganisiwe sepulasitiki sigoqiwe ngokuhamba kwesikhathi ngaphakathi kwe-sheath yangaphandle noma ungqimba lwangaphakathi lokufaka ungqimba njengesendlalelo samanzi.
(3). Khipha i-HDPE Outer Sheath ngqo kwikhebula. Ikhebula le-XLPE elifakwe ngaphezulu kwe-110kV lifakwe i-Sheath yensimbi ukuze ahlangabezane nezidingo ezingavunyelwe. Isihlangu sensimbi sinokuqina okuphelele nokumelana kahle kwamanzi. Izinhlobo eziphambili ze-Metal Sheath yilezi: I-Aluminium Sleeve ecindezelwe eshisayo, i-Hot Fried Lead Sleeve, umkhono we-aluminium ogcwele, umkhono wensimbi owenziwe nge-welded, umkhono wensimbi obandayo, umkhono wensimbi obandayo.
I-3. Ifomu elingangeni manzi lekhebula lamanzi
Ngokuvamile ihlukaniswe ukumelana mpo nasezingeni eliphansi lamanzi amabili. Ukumelana kwamanzi okuqondile kuvame ukusetshenziswaamanzi avimba amanzi, i-powder yamanzi kanye netayitela lokuvimba amanzi, indlela yokuvimba amanzi kulezi zinto zokwakha iqukethe amanzi angakhulisa amanzi, lapho kuvela khona amanzi avela ku-cable ukuvikela okwengeziwe eceleni kwekhebula. Ukumelana kwamanzi ngemisebe kutholakala ikakhulukazi ngokukhipha i-HDPE Not-Metall Sheath noma ukucindezela okushisayo, i-Welding kanye ne-Cold Drawing Metal Sheath.
4. Ukuhlukaniswa kwezintambo ezingamanzi
Kunezinhlobo ezintathu zezintambo zezintambo ezingenamanzi ezisetshenziswa eChina:
(1). Ikhebula le-OUT-POPET elifakiwe yikhebula elijwayelekile kakhulu lokumelana kwamanzi. Ukufakelwa kwayo kanye nabaqhubi bagcwaliswe ngamafutha amakhebula, futhi kunejecter yensimbi (ijakhethi ye-lead noma i-aluminium) ngaphandle kokufakelwa, okuyikho intambo engcono kakhulu yokumelana kwamanzi. Esikhathini esedlule, amakhebuli amaningi asemanzini (noma ngaphansi kwamanzi) asetshenziswa amakheshana kawoyela afakwayo kawoyela, kepha amakhekhe wephepha elifakwe amafutha akhawulelwe yi-Drop, kunenkinga yokuvuza kawoyela, futhi manje asetshenziswa kancane.
(2). I-ethylene proplene rubber elethelwe i-cable esetshenziswe kabanzi kumandla kagesi aphansi naphakathi nendawo, ngenxa yokusebenza kwayo okuphezulu kokufakelwa ngaphandle kokukhathazeka "kwesihlahla samanzi". Ikhebula elinamanzi elinomsindo werabha (uhlobo lwe-jhs) lungasebenza ngokuphepha emanzini angajulile.
(3). I-polyethylene exhumene ne-cross ukunciphisa impilo yenkonzo yekhebula. Ngakho-ke, ikhebula elixhumene ne-polyethylene elihlanganisiwe, ikakhulukazi ikhebula le-voltage eliphakathi nendawo eliphakeme ngaphansi kwesenzo se-ac voltage, kufanele ibe "nesakhiwo sokuvimba amanzi" lapho isetshenziswa endaweni yamanzi noma imvelo emanzi.
5. Umehluko phakathi kwekhebula elingangeni manzi nentambo ejwayelekile
Umehluko phakathi kwamakhebuli angenamanzi nezintambo ezijwayelekile ukuthi izintambo ezijwayelekile azikwazi ukusetshenziswa emanzini. Ikhebula le-JHS materproof libuye libe uhlobo lwekhebula eliguquguqukayo lenjoloba, ukufakwa kwe-ruble ukufakwa kwenjoloba, nentambo evamile yenjoloba, ikhebula lamanzi angenamanzi livame ukusetshenziswa, kepha lisemanzini noma amanye azodlula emanzini. Izintambo zamanzi ngokuvamile zingu-3 umnyombo, iningi lazo liyasetshenziswa lapho lixhuma iphampu, intengo yezintambo ezingama-materproof izobiza kakhulu kunezintambo ezijwayelekile zenjoloba, kunzima ukukhombisa umthengisi ukuze wazi ungqimba lwamanzi.
6. Umehluko phakathi kwekhebula lamanzi nentambo yokumelana kwamanzi
Ikhebula elingangeni manzi
Intambo yokuvinjwa kwamanzi: Ukuhlolwa kuvumela amanzi ukungena ngaphakathi kwekhebula, futhi akuvumeli ukungena kubude obucacisiwe ngaphansi kwezimo ezibekiwe. Intambo yokuvinjwa kwamanzi ihlukaniswe ngama-conductor amanzi okuvinjwa kanye nokuvinjwa kwamakhekhe.
Ukwakheka kwamanzi okuvimba amanzi
Ukwakheka kwamanzi okuvinjwa kwamanzi okuyisisekelo sekhebula: Lapho i-sheath yangaphandle ilimele futhi amanzi angena, itheyiphu yokuvinjwa kwamanzi iyanda. Lapho amanzi evimba amanzi ekhula, yakha ngokushesha ingxenye yokuvinjwa kwamanzi ukuvikela okunye ukungena kwamanzi. Kwintambo emithathu-emithathu, kunzima kakhulu ukufeza ukumelana kwamanzi okujwayelekile kwekhebula, ngoba igebe eliphakathi lekhebula le-cable likhulu futhi lingelona iqiniso, kunconywa ukuthi kukhiqizwe umnyombo ngamunye ngokuya ngesakhiwo sokumelana namanzi okukodwa, bese kumiswa ikhebula.
