钾盐矿井6千伏配电线路个别线段的线路较长(达8公里)。为了限制短路电流,井下中央变电站的供电母线加装了电抗器(图1),接于井下中央变电站(ЦΠΠ)的一组母线设备容量是6—7兆伏安。在这种
Potash salt 6 kV distribution lines of individual lines longer (up to 8 km). In order to limit the short-circuit current, the reactors are installed on the power supply busbar of the underground central substation (Figure 1). The capacity of a group of busbar equipment connected to the underground central substation (ЦΠΠ) is 6-7 MVA. In this kind of
