一、交流杂散电流产生的原因我们在测定阳泉三矿一号井采区的瓦斯支管时发现了交流杂散电流。采区内的瓦斯支管是与井下交流电网的胶皮电缆平行的。如图1所示。井下采区电网是经过高阻抗接 First, the reasons for the exchange of stray current We found in the Yangquan No. 3 mine gas manifold found when the AC stray current. The gas manifolds in the mining area are parallel to the rubber cables of the underground AC grid. As shown in Figure 1. Downhole mining area grid is connected by high impedance
