摘要
众所周知,山区铁路电力通过的电压为10 kV。实践表明,会有较大的接地电阻发生在运输的过程中,而这些电阻会带来较大的安全威胁,需要引起人们足够的重视。其中非常重要的一个问题就是土壤电阻率较高。那么,在如今的形势下,迫切需要解决的问题就是降低山区铁路电力10 kV贯通线路接地电阻。
It is well known voltage electricity through the mountain railway to 10 kV. Practice shows that there is a greater grounding resistance occurs during transport, whereas the resistance will bring greater security threat, need to attract enough attention. One of the very important issues is high soil resistivity. Well, in today’s situation, the urgent need to address the problem is to reduce the mountain railway for 10 kV line to ground cutthrough a resistor.
