在煤矿生产用电中,井下用电占较大比重,用电设备分布在各个采区,从各个采区变电所馈电。因此,在采区变电所低压电网上采取措施,最方便易行,也最易显示其经济效益。矿用动力变压器的运行、停运、负荷多少,都直接与节电有关,故在采区变电所采取机动调荷,是节电的重要措施之一。
In coal mine production electricity, underground electricity accounts for a large proportion of electricity-consuming equipment distributed in various mining areas, from the various mining substations feed. Therefore, the measures adopted in the low-voltage power grids of the mining area substations are the most convenient and easy to be carried out, and the economic benefits are also the easiest to show. Mine power transformer operation, outage, how much load, are directly related to energy-saving, so the mining area to take the motor load transfer substation, is one of the important measures of saving.
