摘要
煤矿井下采掘电动机起动和正常运行时的电压水平是决定采区电网输送能力的主要指标,网络电压损失的计算是必要的,但一些公式计算比较复杂,现有资料中的技术数据也不能满足设备更新的要求,针对这一问题,通过对各种方法的分析比较,并结合工作实践,总结出简单实用的计算方法。
Voltage level of starting and normal operation of mining machine underground remains the main index of powering transportation of mining area, it is necessary to calculate net voltage loss, with complex formula calculation, the current data cannot meet the needs of equipment upgrade, based on the problem, the simple calculation was got by comparison and practice.
