Umzi-mveliso onzima usetyenzise umbane ophantsi wamandla kaloliwe oThutha iinqwelo
inkcazelo
Iinqwelo zomzila we-low-voltage zisebenzisa umbane ophantsi kwe-voltage, ngokuqhelekileyo i-36V, ukuqinisekisa ukusebenza okukhuselekileyo kunye nokunciphisa umngcipheko wokutshatyalaliswa kombane. Ngokuxhomekeke kumthamo womthwalo, iinqwelo zikaloliwe ezine-voltage ephantsi zinemilinganiselo emibini:
(1) Ifanele izithuthi ezinomthamo weetoni ezingama-50 okanye ngaphantsi, isebenzisa i-36V yesigaba sesibini sombane.
(2) Iimoto ezithe tyaba zombane ezinomthwalo ongaphezu kweetoni ezingama-70 zisebenzisa i-36V yamanqanaba amathathu ombane, kwaye i-voltage inyuswe ukuya kwi-380V ngokusebenzisa i-transformer yokunyuka ukuhlangabezana nemfuno.
Isicelo
Iinqwelo zikaloliwe ezine-voltage ephantsi zisetyenziswa ngokubanzi kwiindawo ezahlukeneyo zemizi-mveliso, ezifana nemveliso, indawo yokugcina impahla kunye nokuhanjiswa kwezinto, imigca yokuhlanganisana, imveliso enzima, ukwakhiwa kweenqanawa, kunye nokuveliswa kweemoto. Zisetyenziselwa ukuthutha imathiriyeli ekrwada, iimveliso ezigqityiweyo, iimveliso ezigqityiweyo, iimpahla, iipalethi, iishelufu, kunye neenxalenye zoomatshini abanzima.
Inzuzo
(1) Ukuphucula ukusebenza kakuhle: Inqwelo yokuhambisa umbane ingasebenza ngokuqhubekayo kwaye ayichatshazelwa kukukhathala komntu, okuphucula kakhulu ukuphatha kakuhle.
(2) Ukunciphisa amandla okusebenza: Emva kokusebenzisa inqwelo yokuhambisa umbane, abathwali abafuni ukuthwala uxinzelelo lwezinto ezinzima, ezinciphisa amandla okusebenza.
(3) Ukonga umbane: Xa kuthelekiswa nezithuthi zamafutha, iimoto zombane ezineflethi zinosetyenziso oluphantsi lwamandla kunye nongcoliseko olukhutshwayo.
(4) Ukusebenza okuphezulu kokhuseleko: Ukongeza kwi-low-voltage power supply ukunciphisa umngcipheko wokutshitshiswa kombane, isithuthi sikwaxhotyiswe nge-braking system ukuqinisekisa ukhuseleko lokuqhuba.
(5) Ukugcinwa okulula: Imoto yombane eneflethi inesakhiwo esilula, esinciphisa iindleko zokugcinwa kwezixhobo.
(6) Ukuguquguquka okunamandla: Iimodeli ezahlukeneyo kunye neenkcukacha zinokwenziwa ngokwezifiso ngokweemeko ezahlukeneyo kunye neemfuno.
Ukulumkela
Ekubeni i-low-voltage train car isebenzisa umbane we-low-voltage rail power supply, iileyili kunye namavili kufuneka zifakwe i-insulated. Ngoko ke, ayinakusetyenziswa ngaphandle kwimozulu yemvula, kodwa kufuneka ifakwe kwiindawo ezomileyo okanye ezixutywe kakuhle.
