电气工业
电力输送
力输送中需要大量消耗高导电性的铜,主要用于动力电线电缆、汇流排、变压器、开关、接插元件和联接器等。
在电线电缆的输电过程中,由于电阻发热而白白浪费电能。从节能和经济的角度考虑,目前世界上正在推广""zui佳电缆截面""标准。过去流行的标准,单纯地从降低一次安装投资的角度出发,为了尽量减小电缆截面,以在设计要求的额定电流下,不至出现危险过热,来确定电缆的zui低允许尺寸。按这种标准铺设的电缆,虽然安装费低了;但是在长期使用过程中,电阻能耗却比较大。""zui佳电缆截面""标准,则兼顾一次安装费用和电能消耗这两个因素,适当放大电缆尺寸,以达到节能和zui佳综合经济效益的目的。按照新的标准,电缆截面往往要比老标准加大一倍以上,可以获得50%左右的节能效果。
