Eyokuqala kukutshaja indawo oya kuyo, iyatshaja ngaphandle kwexesha elongezelelweyo lokulinda:
(1) Iindawo zokuhlala zokupaka: Inani elikhulu leengqumba zokutshaja ezicothayo ekwabelwana ngazo kunye nezicothayo ngaphakathi kwe-7kW zakhiwa, kwaye izithuthi zeoyile zinikwa indawo yokuqala yokupaka iindawo zokupaka ezingezozamandla ezintsha, ezinokuhlangabezana neemfuno zabahlali, kwaye iindleko zokubeka iphantsi ngokwentelekiso, kwaye indlela yolawulo elungeleleneyo inokunqanda ukugqitha igridi yamandla ommandla.umthamo.
(2) Udederhu lweevenkile/iindawo ezibukekayo/iipaki zemizi-mveliso/izakhiwo zee-ofisi/iihotele nezinye iindawo zokumisa izithuthi: Ukutshaja okukhawulezayo kwama-20kW kuyongezelela, kunye nenani elikhulu lokutshaja okucothayo kwe-7kW.Icala lophuhliso: ixabiso eliphantsi lokutshaja okucothayo kwaye akukho ndleko yokwandisa;icala labathengi: kunqanda ukuhlala kwindawo / iimoto ezihambayo emva kokutshaja ngokukhawuleza kuhlawulwe ngokupheleleyo ngexesha elifutshane.
Okwesibini kukuzaliswa kwamandla okukhawulezayo, indlela yokulondoloza ixesha lokusetyenziswa kwamandla ngokubanzi:
(1) Indawo yenkonzo ye-Expressway: gcina inani langoku lokutshaja ngokukhawuleza, unciphise ngokungqongqo umda ophezulu wokutshaja (njenge-90% -85% ye-peak), kwaye uqinisekise ukukhawuleza kwesantya sokuqhuba izithuthi ezide.
(2) Izikhululo zerhasi kufutshane nesango lokungena kuhola wendlela kwizixeko/iidolophu ezinkulu: misela ukutshaja okukhawulezayo kwamandla aphezulu, kwaye unciphise ngokungqongqo umda ongentla wokutshaja (ofana ne-90% -85% kwincopho), njengesongezelelo kwindawo yenkonzo yesantya esiphezulu, kufutshane nokuqhuba umgama omde wabasebenzisi bamandla amatsha afunwayo, ngelixa usasaza imfuno yokutshaja kwedolophu / yedolophu.Qaphela: Ngesiqhelo, isikhululo serhasi esisezantsi sixhotyiswe ngamandla ombane angama-250kVA, anokuxhasa ngokuqikelelwayo iimfumba ezimbini zokutshaja ngokukhawuleza kwe-100kW ngaxeshanye.
(3) Isikhululo serhasi esisedolophini/indawo yokupaka emoyeni evulekileyo: misela ukutshaja okukhawulezayo kwamandla amakhulu ukucutha umda ongaphezulu wokutshaja.Okwangoku, i-PetroChina ihambisa ngokukhawuleza ukutshaja / ukutshintshiselana kwiindawo ezintsha zamandla, kwaye kulindeleke ukuba izikhululo ezininzi zegesi ziza kuxhotyiswa ngeemfumba zokutshaja ngokukhawuleza kwixesha elizayo.
Qaphela: Indawo yejografi yesikhululo segesi / indawo yokupaka i-open-air ngokwayo isondele kwindlela kwaye iimpawu zesakhiwo zibonakala zicacile, ezilungele ukuhlawula abathengi ukuba bafumane ngokukhawuleza imfumba kwaye bashiye indawo ngokukhawuleza.
06.Bhala ekugqibeleni
Okwangoku, inkqubo ye-800V isajongene nobunzima obuninzi kwiindleko, iteknoloji kunye neziseko.Obu bunzima bukuphela kwendlela yokwenza izinto ezintsha kunye nophuhliso lobuchwepheshe bezithuthi zamandla amatsha kunye nokuphindaphindwa kwemizi-mveliso.iqonga.
Iinkampani zemoto zaseTshayina, ezinobuchwephesha obukhawulezayo nobusebenzayo bezicelo zobunjineli, ziyakwazi ukuqaphela inani elikhulu lezicelo ezikhawulezayo ze-800V iinkqubo, kwaye zikhokele ekukhokeleni umkhwa wetekhnoloji kwicandelo lezithuthi zamandla amatsha.
Abathengi baseTshayina baya kuba ngabokuqala ukonwabela amava ezithuthi ezikumgangatho ophezulu eziziswa yinkqubela phambili yetekhnoloji.Akusafani nexesha lezithuthi zamafutha, xa abathengi basekhaya bethenga iimodeli ezindala kwiinkampani zeemoto zamazwe ngamazwe, itekhnoloji yakudala okanye itekhnoloji ethenwayo.
