6平方线短距离可以承受功率多大
48乘以220伏电压等于10560瓦,就是6平方电线的最大承受功率。如果是铝芯线,线径乘以6就是最大安全电流。电流乘以220伏电压,就是这根铝线的最大承受功率。在平时使用普通塑料绝缘铜线(~220V)时: 明线的话,1.5平方suo yi ,6 ping fang tong xian neng cheng shou de gong lv yue wei 2 . 8 wa 。tong de dian zu lv yue wei 1 . 6 8 x 1 0^ - 8 Ω · m 。jia she 6 ping fang tong xian de chang du wei 1 mi 。shou xian ,ji suan tong xian de dian zu zhi ,shi yong gong shi :R = ρ * (L / A "
所以,6平方铜线能承受的功率约为2.8瓦。铜的电阻率约为1.68 x 10^-8 Ω·m。假设6平方铜线的度为1米。首先,计算铜线的电阻值,使用公式:R = ρ * (L/A4 8 cheng yi 2 2 0fu dian ya deng yu 1 05 6 0wa , jiu shi 6 ping fang dian xian de zui da cheng shou gong lv 。ru guo shi lv xin xian , xian jing cheng yi 6 jiu shi zui da an quan dian liu 。dian liu cheng yi 2 2 0fu dian ya , jiu shi zhe gen lv xian de zui da cheng shou gong lv 。zai ping shi shi yong pu tong su liao jue yuan tong xian ( ~ 2 2 0V ) shi : ming xian de hua , 1 . 5 ping fang "
yin ci liu ping fang xian ke yi cheng zai 8 . 8 qian wa 。ruo cai yong dan xiang 2 2 0fu de dian ya ,ze liu ping fang guo biao tong xian ke cheng zai yue 8 qian wa ,ruo cai yong 3 8 0fu de dian ya ,ze ke cheng zai yue 1 3 qian wa 。zha kan quan wen 4 1 3 6 * * * * " 因此六平方线可以承载8.8千瓦。若采用单相220伏的电压,则六平方标铜线可承载约8千瓦,若采用380伏的电压,则可承载约13千瓦。查看全文4 136****
