Kokubili i-YJY ne-YJV yimikhiqizo yezintambo neyekhebula evame ukusetshenziswa kubunjiniyela nokwakha, futhi isetshenziselwa izintambo zokuhambisa amandla.Kodwa-ke, amamodeli kanye nokucaciswa kwawo kokubili kuhlukile.Ingabe ukhona umehluko wento kanye nentengo yesheath?Ngezansi, umhleli uzokwabelana nawe umehluko phakathi kwe-YJY ne-YJV.
Ikhebula le-YJY
Ngenisa
I-YJY——Ikhebula lamandla eligqunywe nge-polyethylene evalekile, ikhebula lamandla elenziwe ngezinto ze-polyethylene linezakhiwo ezinhle kakhulu ze-thermomechanical, ukusebenza okuncisha ilangabi okuphakeme kakhulu, futhi i-ampacity ingcono kunaleyo yezintambo zamandla ze-YJV ezivamile, futhi ithuthukisa nokusebenza kwekhebula.ukusebenza kukagesi kanye nezici zokumelana nokushisa.
I-YJ——i-polyethylene exhumene
Y——i-polyethylene
Isicelo
Ingabekwa endlini, emapayipini noma enhlabathini exegayo, inqobo nje uma ingakwazi ukumelana nokushuba nokucindezela;ingasetshenziswa kumanethiwekhi okusabalalisa noma ukufakwa kwezimboni okunezinga likagesi elingu-1-1000kV nangaphezulu, njengeziteshi zikagesi, izintambo zokukhanyisa zasemadolobheni, kanye nokudluliswa kwamandla kagesi ombhoshongo onamandla amakhulu, ukudluliswa kwamandla angaphansi kanye nezinye izindawo.
Izici
Izintambo ze-YJY zilula ngesakhiwo, zilinganiselwe ngobulukhuni nokuthambile, futhi zilungele ukuthuthwa, kodwa azicindezeli, ngakho-ke kufanele kuqashelwe uma uzigcina noma uzithutha.
Inzuzo
Ngokwezidingo zabanye abasebenzisi, i-YJY Power Cable ingakhiqiza izintambo ezisetshenziswa ezikhathini ezidingeka kakhulu njenge-flame-retardant (ZB), ukumelana nomlilo (NH), kanye nentuthu ephansi ne-low-halogen (WDZ).Lawa makhebuli anokuphepha okuphezulu kanye nokusebenza, futhi ayihambisani nemvelo.Ukusebenza okuqinile.
Ikhebula le-YJV
Ikhebula le-YJV libizwa nangokuthi intambo yamandla ye-polyethylene ehlanganiswe ne-PVC eneshehethi yamandla.Phakathi kwazo, i-YJ imele ukufakwa kwe-polyethylene okuxhumene nesiphambano, kanti u-V umele i-polyvinyl chloride sheath.Phakathi kwazo, i-YJV iphinde imele ikhebula eliwumgogodla wethusi, kuyilapho i-YJLV imele ikhebula eliwumgogodla we-aluminium.
NO.1 indlela yokubeka
1. I-YJV, i-YJLV yethusi (i-aluminium) engumgogodla we-XLPE we-PVC efakwe ngaphakathi ibekwe endlini, emiseleni namapayipi, futhi ingangcwatshwa emhlabathini ovulekile, kodwa ayikwazi ukubekezelela ingcindezi namandla angaphandle emishini.
2. I-YJV22, i-YJLV22 yethusi (i-aluminium) ingqikithi ye-XLPE yensimbi evalekile izintambo zamandla aneshehethi ye-PVC zibekwe ngaphansi komhlaba futhi zingakwazi ukumelana namandla emishini angaphandle, kodwa azikwazi ukumelana namandla amakhulu aqinile.
NO.2 Sebenzisa izici
Izinga lokushisa elilinganiselwe eliphezulu lekhondatha yekhebula ngu-90°C.Uma i-short-circuited (ubude besikhathi esiphezulu abudluli ku-5S), izinga lokushisa eliphezulu le-conductor yekhebula alidluli ku-250°C.Izinga lokushisa elizungezile lapho ubeka ikhebula akufanele libe ngaphansi kuka-0°C.Irediyasi yokugoba evumelekile lapho ubeka: ikhebula eliwumgogodla owodwa alikho ngaphansi kwezikhathi eziyi-15 ububanzi bangaphandle bekhebula;ikhebula lezintambo eziningi alikho ngaphansi kwezikhathi ezingu-10 ububanzi bangaphandle bekhebula.
NO.3 Indlela yokukhetha
I-voltage elinganiselwe yekhebula imelelwa i-U0/U(Um): I-U0 iyi-voltage yefrikhwensi yamandla elinganiselwe phakathi kwe-conductor yomklamo wekhebula kanye nesivikelo esiphansi noma sensimbi, i-U iyi-voltage yefrikhwensi yamandla elinganiselwe phakathi kwamakhondatha wokuklama ikhebula, Um. iyinani eliphezulu levolthi yesistimu ephakeme kakhulu idivayisi engakwazi ukumelana nayo.Ngokusho kwemvelo ehlukene yokubeka kanye nomthwalo wekhebula, ukucaciswa namamodeli wekhebula kwakhiwa futhi kukhethiwe.
Uhlobo lwe-non-armored lufaneleka phezulu, ngaphakathi, umhubhe, i-cable trench nezinye izikhathi, futhi alukwazi ukuthwala amandla omshini angaphandle.Uhlobo lwezikhali lungangcwatshwa ngokuqondile emhlabathini ngaphandle kwemibandela esebenzayo yohlobo olungahlosiwe.Ingakwazi ukuthwala amandla athile angaphandle.Izintambo eziwumgogodla owodwa azivunyelwe ukufakwa emapayipini akhiqiza uzibuthe.Izinhlobo ezikhethekile zezintambo kufanele zikhethelwe ukuvutha, ukuqhuma, ukugqwala kwamakhemikhali, izinga lokushisa eliphezulu, izinga lokushisa eliphansi nezinye izikhathi.
Umehluko
Okokuqala nje, i-YJY inokumelana namanzi okungcono kanye nokumelana nezinga lokushisa eliphansi kune-YJV, futhi i-YJV inokubambezeleka okungcono kwelangabi kune-YJY.Izinga lokushisa eliphezulu elilinganiselwe lokusebenza le-YJY cross-linked polyethylene insulated power cable conductor lingu-90°C, eliphakeme kunalelo lezintambo ezigqunywe nge-polyethylene, ngakho umthamo wamanje wokuthwala wekhebula nawo uyanda.Ukushisa okulinganiselwe okulinganiselwe kokusebenza komqhubi kungu-90 ° C, futhi izinga lokushisa eliphezulu le-short-circuit ye-conductor akufanele lidlule i-250 ° C, futhi isikhathi eside kakhulu ngeke sidlule imizuzwana emi-5.Ikhebula le-YJV linezakhiwo ezinhle kakhulu ze-thermomechanical, izakhiwo zikagesi ezinhle kakhulu kanye nokumelana nokugqwala kwamakhemikhali.Ibuye ibe nezinzuzo zesakhiwo esilula, isisindo esincane, futhi akukho mkhawulo ekubekeni ukuphakama.Kuyintambo yenoveli okwamanje esetshenziswa kabanzi kumagridi kagesi asemadolobheni, ezimayini nasezimbonini.
Okwesibili, umgodla we-YJV yi-PVC, okuyikhebula eliqukethe i-halogen;umgodla we-YJY yi-polyethylene, okuyikhebula elingenayo i-halogen.
Ekugcineni, intengo yekhebula ye-YJY iphezulu.I-YJY iyikhebula yamandla e-copper core exhunywe nge-polyethylene egqunywe nge-polyethylene sheathed, futhi i-YJV iyikhebula yamandla e-copper core exhunywe nge-polyethylene insulated polyvinyl chloride sheathed power cable.Kodwa-ke, intengo yezinto ze-XLPE iphakeme kunaleyo yezinto ze-PVC, okuholela ezindlekweni eziphezulu ze-YJY.
