电力是一种宝贵的二次能源,是发展国民经济、提高人民生活水平的物质基础。电力在传递过程中要损耗一小部分有功功率与电量,所损失的这一部分电力称为线损。损耗电量占总传递电量(包括损耗电量在内)的百分比称为线损率。电力系统输电网线损率为8～10％。1988年我国线损率为8.85％。工矿企业(有井下开采的矿山企业)内部配电系统线损率在15％左右,有的高达30％,损耗是
Electricity is a precious secondary energy source, which is the material basis for developing the national economy and improving people’s living standard. Power transmission in the process of loss of a small part of the active power and power, the loss of this part of the power known as line loss. The percentage of the total power lost (including the amount of power lost) is called the line loss rate. Power system transmission line loss rate of 8 to 10%. In 1988, China’s wire loss rate was 8.85%. Industrial and mining enterprises (underground mining companies) internal power distribution system line loss rate of about 15%, and some as high as 30% loss is
