I-JKLYJ 0.6/10KV 16-240mm I-1 engundoqo yeAluminiyam intambo egqunyiweyo engaphezulu
Ingcaciso yeMveliso
Intambo ye-insulated engaphezulu ineempawu zokuhanjiswa kwamandla amakhulu kunye namandla anamandla omatshini.Xa kuthelekiswa neengcingo ezingenanto, ineenzuzo zokubeka isithuba esincinci, ukhuseleko oluphezulu kunye nokuthembeka, kunye nokuchasana kakuhle nokuguga kwe-atmospheric.Iiracks zisetyenziselwa ngokukhethekileyo iiprojekthi zokuhambisa umbane ezidolophini nasezilalini.
Le mveliso ifanelekile kwiintambo zamandla ezingaphezulu kunye nokuhanjiswa kunye nokuhanjiswa kweentambo kunye ne-AC ye-voltage elinganiswe ngu-U (Um) 10 (12) KV nangaphantsi kwizakhiwo eziphakamileyo ezidolophini, iindawo zophuhliso lwabakhenkethi, iindawo zamahlathi, njl.
U-JK umele i-overhead
L imele umqhubi lucingo lwealuminiyam,
Y imele i-polyethylene,
I-YJ imele i-polyethylene edityanisiweyo,
Intambo egqunywe phezulu ye-JKLY.
Imiyalelo yeMveliso yokusetyenziswa
(1) I-voltage elinganisiweyo yentambo yi-10 kV.
(2) Ubukhulu.ixesha elide elivumelekileyo lobushushu bokusebenza komqhubi:
I-Xlpe insulation yi-90℃
Ukuxinana okuphezulu kwe-polyethylene ukugquma 75℃
(3) Xa isiphaluka esifutshane (elona xesha lide alikho ngaphezu kwemizuzwana emi-5), elona qondo lobushushu liphezulu lentambo:
I-Xlpe insulation yi-250℃
Uxinaniso oluphezulu lwepolyethylene luyi-150℃.
(4) Ubushushu bokubeka intambo kufuneka bungabi ngaphantsi kwe -- 20℃
(5) Ubuncinane obuvumelekileyo berediyasi yokugoba yentambo:
Intambo engundoqo enye: 20 (D + d);
Intambo ye-Multi-core: 15 (D + d);
Apho: D -- idiameter yangempela yangaphandle yentambo, mm
d -- Olona bubanzi bangaphandle bomqhubi wentambo, mm
Iimpawu zesakhiwo semveliso
1. Xa kuthelekiswa nentsimbi ye-aluminium core aluminium stranded wire, i-insulated overhead cable ineenzuzo zomgama omncinci wofakelo phakathi kweentambo, indawo encitshisiweyo, kunye nokhuseleko oluphezulu.
2. Iintambo ze-insulated ezingaphezulu zisetyenziselwa ukuguqulwa kweegridi zamandla kwizixeko nakwiindawo zamahlathi.Imveliso ilula kwisakhiwo, ikhuselekile ukuyisebenzisa, kwaye inomatshini obalaseleyo, izinto ezibonakalayo kunye nezombane.Ukuchasana okugqwesileyo ekulandeleni umkhondo, ukukhutshwa komphezulu kunye nokuchasana kwe-atmospheric.Ngexesha elifanayo, xa ikhebula elingaphezulu lisetyenziselwa ukuhanjiswa kwamandla okude kwiindawo ezisemaphandleni, ixabiso le-cable inductance liphantsi kakhulu, kwaye ukuhla kwamandla ombane kuncinci.Musa ukwandisa imilinganiselo yokunyusa, enenzuzo ephezulu yezoqoqosho.
