摘要
介绍变压器中性点直接接地和不接地系统中人身触电电流的计算方法。并通过对比，找出井下变压器中性点不允许直接接地的原因。
This paper introduces the calculating method of person shocking current in the sysytem of power supply of neutral dot directground connection and not ground connection.Through contrast analysis,finds the reason of not allowed direct ground connection for transformer under the shaft.
