化工矿山内部高压网路配电电压的选择是电力设计中重要的一环。大、中型化工矿山的电力负荷不太大,矿区内部高压网路常采用6千伏和10千伏。这两种电压同属一个绝缘等级,线路投资相差无几。但是线路上的电能损耗都相差三倍。因此,当企业内部设有6千伏用电设备,采用10千伏作为企业内部的配电电压是合理的。但在有些化工矿
The selection of distribution voltage in high-voltage network of chemical mine is an important part in the design of electric power. Large and medium-sized chemical mine power load is not too large, high-pressure network within the mining area often use 6 kV and 10 kV. These two kinds of voltage belong to the same insulation grade, the line investment is almost the same. However, the power loss on the line is three times different. Therefore, when the company has 6 kV internal power supply equipment, the use of 10 kV as the distribution voltage within the enterprise is reasonable. But in some chemical mine
