Kwintsimi yeZithuthi zaMandla amatsha (EV, PHEV, HEV), ukukhethwa kwemathiriyeli yeentambo zombane ophezulu kubalulekile kukhuseleko lwesithuthi, ukuqina, kunye nokusebenza. I-polyethylene edibeneyo (i-XLPE) kunye ne-rubber ye-silicone zimbini zezona zinto zixhaphakileyo zokugquma, kodwa zineeyantlukwano eziphawulekayo ekusebenzeni kobushushu obuphezulu, iimpawu zokugquma, amandla omatshini, kunye nokunye.
Ngokubanzi, zombiniXLPEkunye nerabha ye-silicone isetyenziswa kakhulu kwiintambo zangaphakathi zeemoto. Ke, yeyiphi imathiriyeli efanelekileyo ngakumbi kwiintambo zombane ophezulu kwiimoto zamandla amatsha?
Kutheni le nto iiCables eziPhezulu zoMbane weZithuthi zaMandla amatsha zifuna iMathiriyeli yokuKhusela okuPhezulu?
Iintambo zamandla ombane aphezulu kwizithuthi zamandla amatsha zisetyenziselwa ikakhulu ipakethe yebhetri, iimoto, inkqubo yolawulo lombane, kunye nenkqubo yokutshaja, enevoltage esebenzayo ukusuka kwi-600V ukuya kwi-1500V, okanye nangaphezulu.
Oku kufuna ukuba iintambo zibe:
I-1) Ukusebenza kakuhle kwe-insulation ukukhusela ukuchithwa kombane kunye nokuqinisekisa ukhuseleko.
I-2) Ukuchasana okubalaseleyo kobushushu obuphezulu ukumelana neendawo zokusebenza ezinzima kunye nokuthintela ukuthotywa kwe-insulation.
3) Ukuchasana okunamandla kuxinzelelo lomatshini, ukugoba, ukungcangcazela, kunye nokunxiba.
I-4) Ukuchasana nokugqwesa kweekhemikhali ezilungileyo ukulungelelanisa neendawo ezinzima kunye nokwandisa ubomi benkonzo.
Okwangoku, iileyiti zokugquma zeentambo zombane ophezulu kwiimoto zamandla amatsha zisebenzisa i-XLPE okanye irabha ye-silicone. Ngezantsi, siza kwenza uthelekiso oluneenkcukacha zezi zinto zimbini.
Ukusuka kwitheyibhile, kunokubonwa ukuba i-XLPE yenza ngcono malunga nokumelana nombane, amandla omatshini, ukuchasana nokuguga, kunye nokulawulwa kweendleko, ngelixa i-rubber ye-silicone ineenzuzo ekuchaseni ukushisa okuphezulu kunye nokuguquguquka.
Kutheni le nto i-XLPE isesona sixhobo siKhethiweyo kwiiCables zombane oPhezulu kwiZithuthi zaMandla amatsha?
1) Ukusebenza okunamandla kwe-Insulation:XLPEinamandla aphezulu e-dielectric (≥30kV/mm), okwenza kube ngcono ekuxhathiseni iingozi zokuphuka kombane kwiindawo eziphezulu zombane xa kuthelekiswa nerabha ye-silicone. Ukongezelela, i-XLPE inokulahlekelwa kwe-dielectric ephantsi, iqinisekisa ukusebenza okuzinzile kwexesha elide, okwenza ukuba ifaneleke kwiinkqubo zamandla ezithuthi zamandla amatsha.
2) IiPropati ezingcono zoomatshini: Ngexesha lokuqhuba, ukungcangcazela okuvela kumzimba wesithuthi kunokubeka uxinzelelo lomatshini kwiintambo. I-XLPE inamandla aphezulu okuqina, ukumelana nokunxiba okungcono, kunye nokumelana nokusika okuphezulu, okwenza ukuba ifaneleke ngakumbi ukusetyenziswa kwexesha elide kunye nokunciphisa iindleko zokulondoloza xa kuthelekiswa nerabha ye-silicone.
I-3) Ukuchasana nokuguga okungcono: I-XLPE inokumelana nokuguga kwamanzi, iqinisekisa ukuba ikhebula lihlala lizinzile kumswakama ophezulu kunye neendawo eziphezulu zombane. Oku kubalulekile kwiimoto zamandla amatsha, ngakumbi kwizicelo ezinomthwalo omkhulu onje ngeepakethi zebhetri ezinombane ophezulu kunye neenkqubo zokutshaja ngokukhawuleza.
I-4) Ukuguquguquka okuPhakathi ukuHlangana neeMfuno ze-Wiring: Xa kuthelekiswa nerubha ye-silicone, i-XLPE inikeza ukuguquguquka okuphakathi, ukulinganisa ukuguquguquka kwe-wiring kunye namandla omatshini. Isebenza ngokugqwesileyo kwizicelo ezinje ngeentambo zombane ophezulu wemoto, iintambo zokulawula iimoto, kunye noqhagamshelo lwebhetri.
I-5) Ixabiso elithe xaxa: I-XLPE inexabiso elingaphezulu kune-rubber ye-silicone, exhasa ukuveliswa kobuninzi. Iye yaba yinto eqhelekileyo kwiintambo zombane ophezulu kwiimoto zamandla amatsha.
Uhlalutyo lwemeko yeSicelo: XLPE vs Silicone Rubber
I-XLPE, enokumelana namandla ombane okugqwesileyo, ukomelela koomatshini, kunye noncedo lweendleko, ikhuphisana ngakumbi ekufakeni iintambo zombane ophezulu kwizithuthi zamandla amatsha.
Njengoko itekhnoloji entsha yemoto yamandla iqhubela phambili, imathiriyeli ye-XLPE nayo iyaphuculwa ukuze ihlangabezane neemfuno eziphezulu kwiimeko zesicelo:
I-1) I-XLPE e-High-Temperature Resistant (150℃-200℃): Ifanelekile kwisizukulwana esilandelayo seenkqubo zokuqhuba umbane eziphezulu.
I-2) I-Low-Smoke ye-Zero-Halogen Cross-linked Polyethylene (LSZH): Ihambelana nemigangatho yokusingqongileyo yezithuthi zamandla amatsha.
I-3) I-Optimized Shielding Layer: Yongeza ukuchasana nokuphazamiseka kwe-electromagnetic interference (EMI) kwaye iphucula ukuhambelana kwe-electromagnetic (EMC) yesithuthi.
Lilonke, i-XLPE ikwindawo ebalaseleyo kwicandelo lentambo ye-voltage ephezulu yezithuthi zamandla amatsha ngenxa yokusebenza kwayo okugqwesileyo, ukumelana nombane, amandla oomatshini, kunye nezibonelelo zeendleko. Ngelixa i-rubber ye-silicone ifanelekile kwiindawo eziphakamileyo zokushisa, ixabiso layo eliphezulu lenza ukuba lilungele iimfuno ezikhethekileyo. Kwiintambo eziqhelekileyo zombane we-voltage kwizithuthi ezintsha zamandla, i-XLPE lolona khetho lungcono kwaye lunokusetyenziswa ngokubanzi kwiindawo eziphambili ezifana neentambo zebhetri, iintambo ze-motor high-voltage, kunye neentambo zokutshaja ngokukhawuleza.
Kumxholo wophuhliso olukhawulezayo lweshishini elitsha lezithuthi zamandla, iinkampani kufuneka ziqwalasele izinto ezinjengeemeko zesicelo, iimfuno zokuxhathisa ubushushu, kunye nohlahlo lwabiwo-mali lweendleko xa ukhetha izinto zentambo zombane ophezulu ukuqinisekisa ukhuseleko kunye nokuqina kweentambo.
