Ikhebula le-VVGG-LS, isisindo sayo nobubanzi obungaphandle

Ikhebula elidumile le-VVGG-LS laklanyelwe ukufakwa kwamagumbi emakamelweni, ngaphandle, ukufakwa kagesi (iziteshi, imigudu, amapayipi, amathreyi, njll) ngaphansi kwesimo sokuthi akukho mithwalo yemithwalo emithini. Imishini yalolu chungechunge iphinde isetshenziswe lapho kubalulekile ukuhlinzeka ukuphepha komlilo okwandisiwe.

I-VVGng LS ikhebula i-VVGng ihlukaniswe yiqiniso lokuthi umklamo wayo usebenzise ukuxhuma, okungenakukwazi ukukhipha umusi omkhulu ngesikhathi sibhenga.

Egameni lensimbi, inkomba ye-LS ibhekisela kuMoya Omncane, ohunyushwa ngokuthi "low-smoke" (ukugcizelela kanye negobolondo zenziwe ngepulasitiki elinamalaki elingafaki ukushisa).

Isicelo

Ikhebula le-VVGng-LS laklanyelwe ukusebenza ezindaweni ezibandayo, ezibandayo noma ezishisayo. Lolu hlobo lwocingo lungasetshenziswa kokubili emhlabathini nasemachibi, imifula ephakeme ngaphezu kolwandle kuze kube ku-4300 m.

Ikhebula lamandla lisetshenzisiwe:

• Emoyeni, kunikeziwe ukuthi akukho monakalo wokulimala komshini ngesikhathi sokusebenza;
• Ezindaweni ezomile noma ezinamanzi (abaqoqi, imigudu, imigodi, izakhiwo zezimboni, izakhiwo ezihambisana nezikhukhula ezincane, njll);
• Emabhuloki, amabhuloho, ama-overpasses akhethekile;
• Ezindaweni eziyingozi;
• Ezakhiweni ezinobungozi bomlilo;
• Ukuze kubekwe amanethiwekhi eqembu lokukhanyisa ezindaweni eziqhumayo.

Isisindo sekhebula ВВГнг-LS sivumela ukuyisebenzisa emigwaqweni eqondile, enezingqimba noma ezithambekeleyo. Lolu hlobo lwezingcingo ezingenalutho lungaqhutshwa ezindaweni ezinokudlidliza.

Akunconywa ukuthi usebenzise ukufakwa komhlaba ngaphansi komhlaba (ezingxenyeni zobumba kanye nomhlabathi) ngaphandle kokusebenzisa izinhlelo ezikhethiwe zekhebula (isibonelo, i-metal hose noma amapayipi we-HDPE), okungafaki umonakalo kumgudu womqhubi futhi ugcine izici zokusebenza kulo lonke ukuphila kwawo.

Izici zokuklama

• Abaqhubi benziwe ngethusi futhi bangaba yinkimbinkimbi eyodwa noma yocingo, babe nomumo wesigceme noma oyisiyingi. I-GOST inikeza i-I noma i-II isigaba sokuguquguquka.
• Ukugxilwa kwama-cores kwenziwa nge-polyvinylchloride plastic compound, okwandise ukuvikelwa komlilo nokunciphisa ukukhishwa komusi. Ingqikithi ngayinye ekhonjiwe emicimbini ye-multicore yenziwe nge-PVC yemibala ehlukene. Ngokwesiko, imifino ye-zero inemibala eluhlaza okwesibhakabhaka, ukugxila kuluhlaza okwesibhakabhaka noma kuboniswe inombolo "0".
• Ingxenyeni yangaphakathi yekhebula ihlelwe phezu kwama-insulated conducors, igcwalisa i-voids phakathi kwabo futhi idale ingqimba engavamile yokuzivikela phakathi kokukhipha kwangaphandle kanye nenhloko.
• Igobolondo langaphandle lenziwe yikhamera ye-polyvinyl chloride futhi inomlilo okwenyuka kakhulu. Uma ububanzi bomklamo wekhebula engadluli ku-16 mm, ukugcwalisa isikhala ngenhlanganisela ekhethekile ekhonkisayo phakathi kwekhanda negobolondo langaphandle kuvunyelwe. Kulesi simo, igobolondo langaphakathi lizikhethela.

Ububanzi bekhebula le-VVGng-LS

Imisipha yocingo lwezintambo ezimbili inesisindo esifanayo sokuhlukanisa. Uma inani lezimvini liyi-3-5, enye yazo ingaba ubukhulu obukhulu. Lona ucingo lomhlabathi noma umqhubi we-null.

Ububanzi nobukhulu bekhebula i-VVGng-LS kubalwa kuye ngokuthi inani labaqhubi esakhiweni, izici zokuklama kwayo,

Izici ezinkulu zobuchwepheshe

Ikhebula le-VVGng-LS lisetshenziselwa ukubeka nokufakwa kwamandla kagesi kusuka kwamabhodi okusabalalisa amandla noma okufakelwa kwe-transformer ezintweni zokusetshenziswa kwamandla: ama-workshops okukhiqiza, izakhiwo zokuhlala nezokuphatha, amasayithi wokwakha, izindawo zokusebenzela kanye namabhizinisi osizo, njll. Kuvunyelwe ukubeka ucingo lokunikezela kumateyidi akhonkolo , Ama-tunnels, ngokusekela ngaphezulu.

Ifoni Yenzelwe ukudluliselwa kukagesi, amandla ayo okwenza okunye okukhona okungu-0.66 kV noma i-1 kV njalo.

Igobolondo langaphandle lenziwe ngezinto ezingekho emisebeni ye-ultraviolet, ngakho-ke kuvunyelwe ukubeka umkhiqizo elangeni. Ikhebula le-VVGng-LS Akunconywa ukuba usebenzise ukubeka emanzini omhlaba angavikelekile.

• Ukushisa okuvunyelwe komoya lapho ukusetshenziswa kwekhebula kungasetshenziswa khona -50 ... + 50 ° С
• Ukufudumala kwomoya kuvunyelwe kufika ku-98% (ekushiseni kuka-+35 ° C)
• Ikhebula lingasetshenziswa ekushiseni okungenani -15 ° C
• Ukushisa okusebenzayo kokushisa kwama-cores - +70 ° С
• Isikhulu esiphezulu kwimodi esiphuthumayo yi-+90 ° С (ukusebenza akukona amahora angu-8 ngosuku futhi angaphezu kwamahora angu-1000 phakathi nesikhathi sonke sevisi)
• Ukungahambisani nokushisa kwe-t +400 ° С
• Ubude bekhebula, ububanzi balo buyi-1.5-16 mm, buyi-450 m; Ikhebula elinemivimbo engu 25-70 mm ububanzi - 300 m; Uma ububanzi bemithanjeni buyi 95 mm noma ngaphezulu - 200 m.
• Isikhathi sokusebenza sewaranti kusukela ngosuku lokuthunyelwa yiminyaka engu-5, kusukela ngosuku lokukhiqizwa - kungabi ngaphezu kwezinyanga eziyisithupha.
• Ukuphila komsebenzi kufike eminyakeni engama-30

Ukulawulwa kwekhwalithi

Izindlela zokulawula ezilandelayo zisivumela ukuba senze isiphetho sokuqala mayelana nekhwalithi yekhebula, uma izindinganiso ezitholakala ezilawulwa zihluke kakhulu. Kodwa-ke, isiphetho sokugcina ngokuhambisana nalokhu okushiwo yi-GOST singenziwa kuphela ngemva kokuhlola izivivinywa ezikhethekile ngokuhambisana nezinqubo eziqinile kanye nemigomo ecacisiwe kumgomo.

Ukuhlola okubukwayo nokukala kokulinganisa

Ngokubukeka, ungabheka inombolo nombala wemithanjeni, inani lezintambo emthanjeni, ubuqotho begobolondo nokugxilonga, ukukhululeka kokuhlukana kwabo.

Ngosizo lwamathuluzi wokulinganisa, ungabheka ubukhulu begobolondo nokuxilisa. Ukulinganisa ububanzi benethiwekhi nokubala isigaba esinqunyiwe sezintambo ngefomula ekhethekile akusebenzi ngendlela eqinile yokulawula, ngoba ukuxhumana kwesigaba kuqinisekisa ukumelana kagesi. Kodwa-ke, ukuphambuka okuphawulekayo (ngaphezulu kwezingu-10%) kwesigaba esiphambanwe esibalwe kusukela esigabeni esiphambene nomthetho singase sibe isisekelo sokungabaza ngekhwalithi.

Ukuhlolwa okuphefumulayo ngemva kokugcina ukushisa okuphansi

Ngale ndlela, uma unefriji enkulu enokushisa kwe--15 ° C, ikhwalithi yesikhumba sekhebula ihlolwe, ububanzi obungaphandle obungama-20 mm. Ngalesi sizathu, ubude bekhebula, buhlanganiswe ukuhlanganiswa phakathi kwendandatho (ubude obungaba ngu-1.2 m), bubekwa imizuzu engu-45 efrijini, bese kukhishwa futhi imizuzu emihlanu ukuqhuma kuqhutshwa ngodubhu ngokuphenduka okugcwele. Ububanzi bomdubho kufanele bube ngu-15 ∙ (Dn + d) ± 5%, lapho i-Dn engaphandle ububanzi bekhebula i-VVGng-LS ku-mm, d ububanzi bomgudu ngo-mm. Kule nkinga, igobolondo le-qualitative akumele liphule futhi liphule.
