Armored ikhebula laying emhlabathini: sha, ukubala

Lesi sihloko iyobheka indlela yokwenza izintambo komhlaba zempi. Ngaphezu kwalokho, sibatshela ngo nekukumakwa futhi ngqo mayelana nendlela ukubala wenziwe imigqa.

Izimfuneko laying ikhebula armored emhlabathini

Gasket armored ikhebula imigqa, kanye nanoma yikuphi inqubo ukwakhiwa zingahlukaniswa izigaba. Kubalulekile ukuba acabangele ukulandelana eqondile kanye nokusentshenziswa efanele uhlelo, kanye nokusetshenziswa kwazo zonke izimo ukufakwa.

Ngaphambi kokuba uqale ebeka izintambo, kubalulekile ukuba acabangele nalezi zidingo ezilandelayo:

• Ikhebula umugqa kufanele kube akukho zithiyo ukuze afeze voltage yokusebenza kwe-network, ngakho-ke akufanele kuphazamise amapayipi komhlaba labhubhisa, izimpande zemithi kanye nezinye izinto. Futhi isimiso impermissible of ikhebula imigqa.
• Phakathi Wiring ikhebula sihlinzekela ukuthuthukiswa kwe-pads amanzi esihlabathini noma Imicu yotshani ekhethekile mayelana nalo ngaseziseleni ushona kumele abe phakathi 75 amasentimitha ukuba 1 imitha.
• ikhebula Armored laying emhlabathini kufanele lusekelwe.
• Elingenamikhono kangcono umcamelo indunduma - sandstone, namatshana futhi izinto okunzima amandla omlilo.
• Uma ngesikhathi kubekwa kuyoba kudingekile ukuba luthathe emgodini efanayo babashayeli ezimbili noma ngaphezulu armored, ibanga phakathi emgqeni ikhebula kumele okungenani ibe 11 amasentimitha.
• Uma uxhuma izintambo armored nge Ukunqanyulwa kwe esetshenziswa isandla VLEP.

Ukubeka samakhebula armored emhlabathini

Umsele izintambo i VLEP okunye. stowage uhlelo ulula, kodwa has a kunalokho eside futhi kukhathaza inqubo imisebenzi.

1. Ekulungiseleleni umugqa laying ikhebula armored ukufakwa emhlabathini ukuhlola ubuqotho bayo phezu bonke ubuso. Esimweni lapho ukuthola olimele, ukuwalungisa noma ukwehlukanisa, futhi ukushintshela umonakalo entsha eyodwa ngaphezulu. Kuyadingeka ukukhumbula ukuthi umsebenzi wenziwa nge material kanzima, ngakho ilimaze ke, ogibele sikhipha futhi zigxile ebhokisini.
2. ikhebula Armored laying emhlabathini ayikwazi wabeka ngaphandle icebo. Kufanele kwenziwe ukuthuthukiswa endaweni ekhethekile lapho umsebenzi kuzokwenziwa. uhlelo okunjalo kuyokusiza baqonde izisekelo pads for ezindaweni ezikhethiwe. Yama, njengoba sekushiwo ngenhla, kufanele okungenani 65 amasentimitha ukujula, futhi ububanzi yabalelwa, ikhumbula obuphelele phakathi izintambo futhi izindonga emseleni.
3. Wiring isihlabathi noma pads fibrous phansi emseleni wenze ngisho ungqimba. Khona-ke beka bentambo ngaphandle esisuka - amagagasi.
4. Khona-ke intambo armored ukufakwa emhlabathini ngaphezu kwalokho wathela ungqimba isihlabathi okungenani 10 amasentimitha. Khona ungqimba engenhla isihlabathi isiguqo ivaliwe akhiwe noma itshe. Lokhu kuyadingeka ukuze kuvikelwe izintambo conductive kusukela ukusonteka engahlelelwe lapho kwenziwe imivubukulo eduze site kubekwa.
5. Ngemva emseleni ligcwele isendlalelo esingeziwe 15-20 amasentimitha umhlaba pre tamping ke.

Izici izintambo armored

Amandla armored izintambo laying emhlabathini yakhiwa eyodwa noma ngaphezulu babashayeli zamanje aphethe umqondo. Ikhebula cores zingenziwa izinto ezihlukahlukene conductive, ngokuvamile ikhopha ne-aluminiyamu.

Futhi, kungenzeka izintambo unikezwe umqhubi isisekelo, ngokuvamile it has umyalo ezidlula kwesigaba ngaphansana babashayeli main. Izinto zokuvala umoya liyadingeka ukunikeza ezidingekayo ukumelana kagesi of babashayeli nomunye kanye igobolondo zempi. It is ezenziwe ngezinto ezahlukene polymeric.

Manje cabanga izici zethusi ikhebula zempi. Zempi ikhebuli ezinjalo okwazi ngokuvikela ngokumelene izimo eziyingozi kanye ezonakalisayo kwemvelo. Ithusi ikhebula armored ukufakwa emhlabathini uphelele laying kanye ukufakwa amathrekhi conductive nge okungenzeka enkulu umonakalo. Umkhiqizo yalolu hlobo Twine kudabuke ezimbili armored futhi camera PVC ungqimba.

Iziphi izici uye aluminium armored ikhebula? Babashayeli yalolu hlobo isetshenziselwa izingxenye ezinkulu babashayeli, it is hhayi sesimeni ukugoba eqinile noma ngilulekela ngakho njengoba aluminium - sasivumela impahla ziyaqothuka. Armored aluminium ikhebula laying emhlabathini ezakhiwe emazombezombe tape emhlabeni impahla nangokuvikela lashukumisa noma PVC plasticized.

Izinzuzo izintambo armored

Njengoba for izinzuzo izintambo armored, bungokulandelayo:

1. Amandla amakhulu kanye ukumelana ukucindezeleka mechanical.
2. Ubuncane kusitoreji amasayithi.
3. Long Wesici (eneminyaka engaphansi kwengu-60).
4. Ukumelana ukushaqeka ezishisayo kanye nokwenzeka ukusebenza emazingeni okushisa kusuka -60 kuya +55 Celsius.
5. Ukuthembeka kanye kalula abebeziphilisa ngako.
6. A ezahlukene izicelo.
7. Ukukhetha elikhulu imikhiqizo.
8. Ukuvikeleka ukugqwala futhi umswakama

Izinhlobo zempi phezu yangaphandle ungqimba zokuzivikela

ukuphila isikhathi eside futhi high ukugqwala ukumelana iqinisekisa izinto ezisetshenziselwa ukuvikela ikhebula. Kuye uhlobo isitayela kanye izici ezihlukahlukene zenhlabathi thatha zempi. Omunye izimpawu kakhulu owaziwa AABL, AVBbShv, VBbShv. kwesigaba Cross babashayeli ivela 1.5 mm ² kuya 270 mm ^2. imigqa enjalo ingase ibe inombolo ehlukile izintambo (1 kuya ku 5).

Izinhlobo Ukuvikelwa zangaphandle:

1. Steel metallic kudabuke - zempi enamandla kakhulu, esivikela umugqa kagesi emiphumeleni ngaphandle emzimbeni, isibonelo, phakathi kumbiwa nebhakede Excavator, ehlohla noma nishaye nge crowbar.
2. Steel Stainless wire inikeza ukuzinza yokulwa umswakama futhi ukugqwala.
3. Steel amabhande ekhiqizwa ngesimo corrugations. Lolu hlobo lwe-ikhava zempi ucingo izintambo. ungqimba enjalo inikeza isivikelo esihle umswakama kanye ukudledlezela.

Izitembu izintambo armored

Izitembu armored izintambo laying emhlabathini ezidingekile ukukhethwa izici efanelekayo, ngokusekelwe izimo ukubala. Umnqopho wokugubha kudingekile kokubonisa izici yomkhiqizo:

• eziphilayo impahla;
• aphoyintimenti;
• uhlobo ukwahlukanisa;
• umklamo sici;
• buka Sectional kwe-athikili;
• voltage okuzisholo;
• zamanje esinesilinganiso.

Ngokwesibonelo VBbShv uhlobo conductive, lapho:

• Ngo - core behlukene polyvinyl chloride.
• B - ngesikhwama esivikelayo ungqimba wire zempi eyenziwe amashidi basale dengwane iribhoni Helical.
• B - ibitume ungqimba phakathi umqhubi. Isetshenziselwa babashayeli ezinkulu wahlala.
• BC - i olwelwesini polyvinyl chloride.

Ukubalwa ikhebula imigqa

Njengoba ubona sihloko, namuhla uzotshelwa kanjani ukwenza ukubala. ikhebula Armored laying emhlabathini ibalwa ukukhetha uhlobo elikhulu wire gauge wahlala amandla. Okokuqala okudingekile ukunquma zamanje balinganisela ifomula othulwe ngezansi.

P _n - okuzisholo amandla umthengi Watts.

_K - zabathengi isidingo Coefficient.

U _nge - voltage ukalwe we B. inethiwekhi

cos F - amandla isici umthengi.

n _a - kahle isici inethiwekhi.

Ngokulandelayo, ukubala Kwenziwa ikhebula amandla lokukhanda.

Ngemva kokubala umqhubi cross kwesigaba kuyakhethwa kunangendlela noma ilingane ibalwa.
