Yintoni umahluko wokusebenza phakathi kwezinto ezisetyenziswa kwikhebula ezinciphayo ezibandayo kunye nezinto ezisetyenziswa kwikhebula ezinciphayo ezishushu?

1, Isitywino

Ekubeni uninzi lwezixhobo zekhebula zikwindawo engaphandle, zigqunywe ngqo nakwezinye iindawo, ukungangeni manzi kunye nokumelana nokufuma kuye kwaba yenye yezona zinto zibalulekileyo ukuqinisekisa ukhuseleko lwezixhobo zekhebula, kwaye umsebenzi kunye nendlela yokuzivala kufuneka kuqwalaselwe.

Okwangoku, kukho iindlela ezimbini zokuvala ngokubanzi:

Enye kukuvala nge-asphalt okanye i-epoxy resin, inkqubo ayilungelelani, kunzima ukuyilawula, kwaye ayikhuselekanga.

Enye indlela entsha kukusebenzisa i-sealant ene-elastic ephezulu, elula ukuyisebenzisa, ethembekileyo ekusebenzeni kwayo, kwaye ilungele ukukhusela izixhobo, nto leyo eye yaba yeyona nto iphambili ekusetyenzisweni kwayo. Ukuze sisebenzise le ndlela intsha, kufuneka siqale siqwalasele umsebenzi we-sealant. Kuba umgangatho kunye nomsebenzi we-sealant uchaphazela ngokuthe ngqo umsebenzi we-sealant we-joint.

Izixhobo zekhebula zamandla ezicothayo ngokupheleleyo zizixhobo zekhebula ezithambileyo, oko kukuthi, usebenzisa ukuthamba kwerabha ye-silicone elulwelo okanye eqinileyo ngokwayo, yandisa kumzi-mveliso kwangaphambili, ubeke iplastiki kunye nemicu yokuxhasa, kwaye ususe imicu yokuxhasa kwicala elimiselweyo kwindawo ukuze imfutshane ngokwendalo.

Olu hlobo lobuchule yindlela yokunciphisa intsimbi ngokubandayo, kwaye olu hlobo lwesixhobo sisixhobo sentambo esinciphayo ngokubandayo. Ke ngoko, esi sixhobo sentambo esinciphayo ngokubandayo sinokuguquguquka okugqwesileyo, okunokuthintela intambo ukuba ikhule kwaye inciphe ngenxa yokusingqongileyo okungalinganiyo kunye nomthwalo wokusebenza ongalinganiyo wentambo, oko kukuthi, indawo yokukhusela edalwe kukuphefumla kwentambo.

Ingxaki yezixhobo zekhebula ezincitshiswa bubushushu kukuba aziguquguquki kwaye azikwazi ukuphefumla ngentambo.

Ke ngoko, izixhobo zekhebula ezibandayo ngokupheleleyo zezona zilungileyo kwiindawo ezinomahluko omkhulu kubushushu kunye nempembelelo enkulu yemozulu kunye nokusingqongileyo!

2, Ukuvala ubushushu

Iimfuneko zokufakelwa kwe-insulation zezixhobo zekhebula kufuneka zihlangabezane nokufakelwa kwe-insulation phakathi kwezigaba kunye nokufakelwa kwe-insulation okuchaseneyo.

I-insulation ehambelanayo yirabha ye-silicon kunye nezixhobo zokukhusela ezinciphayo ngobushushu. Ngokubanzi, umsebenzi wokukhusela ubushushu usekwe kwithagethi yokukhusela yeyunithi yezinto, kwaye ubukhulu bezinto ezidibeneyo buhlangabezana neemfuno.

Izixhobo zekhebula ezinciphayo kubanda, isalathisi somsebenzi ngokubanzi yi-24kV/mm, kwaye ubukhulu bokusebenza obucwangcisiweyo kufuneka buhlangabezane nobukhulu be-12mm, obunokumelana novavanyo lombane kunye nombane ogqithisileyo.

Izixhobo zekhebula ezinciphayo zenziwe ngezinto ezahlukeneyo ezidityanisiweyo kwaye zinomsebenzi wokunciphisa ubushushu emva kokulungiswa kwemisebe. Isalathisi sokukhusela iyunithi yi-1.8-2.0kV/mm, kwaye ubukhulu obucwangcisiweyo bubukhulu be-3-4mm kunezinto zerabha ze-silicone. Ukukhusela okunxulumeneyo kumgama okhuselekileyo wokuthintela umbane ukuba unganyuki ukusuka kwi-potential ephezulu ukuya kwi-potential ephantsi.

Izinto zerabha zesilicone ezinciphayo zinobuthambileyo obuhle kakhulu. Lo gama nje ucwangciso lufanelekile, ukuqina kwazo okuqinileyo kunokwanelisa amandla okubamba. Nokuba imeko-bume iyanda okanye inciphayo, izixhobo zekhebula ezinciphayo ziqinisekisa ukuba intambo igotywe ngokuqinileyo ukuthintela ukuphefumla umswakama kunye nokuqinisekisa umgama okhuselekileyo wangaphakathi. Kwangaxeshanye, ngokwethiyori, umgama wangaphakathi wokunyuka kuzo zonke izixhobo zekhebula ezinciphayo zi-70mm kuphela, kodwa ngenxa yezizathu zokhuseleko, umgama wokusebenza ocwangcisiweyo usengu-90mm.

Ubushushu obufutshane bezixhobo zekhebula ezinciphayo buyi-100℃-140℃. Kuphela kwizixhobo apho ubushushu bunokuhlangabezana neemeko zalo zokuncipha. Xa ubushushu buphantsi, kuba i-coefficient yokwandiswa kobushushu yekhebula yahlukile kweyezinto ezinciphayo, imeko-bume engaphantsi kwama-80°C inokwahlukana, ngoko ke kuya kuvela imingxunya, okuvumela amanzi kunye nokufuma ukuba kungene phantsi kwesenzo sokuphefumla, ngaloo ndlela kutshabalalise ubushushu benkqubo. Le yingxaki encinci yezinto ezinciphayo zobushushu.

3, Intsimi yombane

Xa kucutshungulwa intsimi yombane yezinto ezidityanisiweyo zekhebula ezibandayo, kusetyenziswa iindlela ezahlukeneyo ukutshintsha ukusasazwa kwentsimi yombane ngokusebenzisa iikhowuni zoxinzelelo, kwaye kusetyenziswa iimilo ezithile kunye nokucubungula okuchanekileyo kwe-R-viewpoint. Le ndlela ilula ukuyilawula nokuyijonga kwaye ingagqitywa efektri.

Indlela yonyango lwentsimi yombane yezinto ezisetyenziswa kwikhebula ezincitshiswa bubushushu kukutshintsha usasazo lwentsimi yombane ngokusebenzisa iiparameter ezithe ngqo. Kubalulekile ukuxhomekeka kwiiparameter ezimbini ezibalulekileyo:

Ukumelana nomthamo, 108-11Ω.

I-dielectric constant yi-25.

Ngenxa yenkqubo yemveliso engacwangciswanga kunye notshintsho olukhulu kwizinto ezingqongileyo, kunzima ukulawula uzinzo lweeparameter, nto leyo eya kuchaphazela uzinzo lomgangatho wemveliso.

Ngoko ke, izixhobo zekhebula ezinciphayo kubanda kunye nezixhobo zekhebula ezinciphayo kubanda zahlukile ngokupheleleyo kwinkqubo ngokwayo. Ukusebenza phantsi kweemeko eziqhelekileyo, zombini ziyahlangabezana neemfuno zokhuseleko. Nangona kunjalo, njengoko imeko-bume itshintsha, ukuncipha kubanda ngokwenene kuluncedo ngakumbi kunokunciphisa ubushushu. Kakade ke, ixabiso lokuncipha kubanda liphezulu kakhulu kunelo lokuncipha kobushushu.
