I-electrode yegraphite ye-UHP isetyenziswa ikakhulu kwiziko zombane ze-arc zombane ezinoxinzelelo olukhulu kuno-25 A/cm2.
Iinkcukacha zeMveliso
IMVELISO Inkcazo
I-electrode ye-graphite ye-UHP isetyenziselwa ukurisayikilishwa kwentsimbi kwishishini le-arc yombane. Esona sithako saso yinaliti enexabiso eliphezulu eyenziwe ngepetroleum okanye itela yamalahle. I-electrodes yegraphite igqitywe nge-cylinder shape kwaye ifakwe ngoomatshini kunye neendawo ezinemisonto ekupheleni. Ngale ndlela, i-electrode yegraphite inokudityaniswa kwikholamu ye-electrode isebenzisa ingono ye-electrode.
Ukuze kuhlangatyezwane nemfuneko yokusebenza kakuhle kakhulu kunye nexabiso eliphantsi lilonke, umthamo omkhulu wezixhobo zombane ze-arc zisiya zithandwa ngakumbi. Ngenxa yoku, iielectrode zegraphite ze-UHP ezinedayamitha ezingaphezulu kwe-500 mm ziya kulawula ukuthengisa.

IMVELISO Umgangatho womphezulu
● Kufuneka kubekho iziphene ezingaphantsi kweebini okanye imingxuma kwi-electrode surface, ubukhulu becala bukhankanywe kwitshathi engezantsi.
● Akufuneki kubekho iintanda ezinqamlezileyo kumphezulu we-electrode. Kwi-crack longitudinal, ubude kufuneka bube ngaphantsi kwe-5% ye-electrode circumference kunye nobubanzi bube yi-0.3 ukuya kwi-1.0 mm.
● Ububanzi bendawo emnyama kwindawo ye-electrode kufuneka ibe ngaphantsi kwe-1/10 ye-electrode circumference kwaye ubude bube ngaphantsi kwe-1/3 ye-electrode.

Iimveliso ezinxulumeneyo
Ngo-1985, i-Datong Locomotive Works yaqaphela ukuba ii-locomotives zombane yayiyeyona ndlela ibalulekileyo yophuhliso lwe-locomotive kaloliwe wase-China kunye noshishino lwempahla yempahla kwixesha elizayo, kwaye yabeka phambili ingcamango yoyilo lwemveliso ye "Nanzhu (iZhuzhou Electric Locomotive Works) kunye neDatong Locomotive Works".
I-Shaoshan Type 3 locomotive yombane sisizukulwana sesibini selizwe lam labakhweli abane-asi e-6 kunye nelocomotive yempahla. I-locomotive ithatha ibhulorho-uhlobo olupheleleyo ukulungiswa kwamaza kwaye iqonda ukulawulwa kombane ogudileyo wesigaba se-thyristor. I-locomotive ithatha i-single-phase ye-AC 25kV 50Hz inkqubo yombane kwaye inesantya esiphezulu se-100km / h.
I-SS3B egxininisiweyo ye-locomotive yombane enzima yi-12-axle yomthwalo we-locomotive yombane. Iqulethe iilocomotives ezimbini ezifanayo ezine-axle ezi-6 ezidityaniswe yi-coupler kunye ne-windshield. La macandelo mabini axhotyiswe ngesixokelelwano sombane esine-voltage ephezulu, iintambo zokulawula, kunye nokukhusela inethiwekhi. Imibhobho yokulawula umgca kunye nomoya. Isithuthi sonke sinokulawulwa ngolungelelwano kuyo nayiphi na i-cab. I-locomotive ithatha inkqubo ye-frequency power frequency system, i-voltage 25kV, i-AC-DC transmission, kunye nesantya esiphezulu sokusebenza kwi-locomotive yi-100km / h.
I-locomotive yombane i-Shaoshan 4 yi-8-axle yokuthutha impahla. I-locomotive inee-locomotive ezimbini ezifanayo ezine-axle ezine ezidityaniswe yi-coupler kunye ne-windshield. Ezi workshops zimbini zixhotyiswe ngeziqhagamshelo eziphezulu ze-voltage zenkqubo yombane, iintambo zokulawula ukudibanisa kwakhona kunye nemigudu yokulawula i-air brake system. Isithuthi siphela sinokulawulwa ngolungelelwano ukusuka kwikhebhu yomqhubi wayo nayiphi na enye yezithuthi. Izitimela ezimbini zinokwahlulwa kwaye zisetyenziswe ngokuzimeleyo njenge locomotive ene-axle ezine.
