摘要
介绍了接地电阻的概念,从工程计算角度,参考国际标准BS 7430:2011,对某实际工程中建筑物的接地网络建立模型并计算出工频接地电阻。实践证明,工频接地电阻在实际工程中的计算,对接地系统设计有更明确的指导意义。
The paper introduces the concept of earthing resistance, establishes a model for the earthing grid of a building in an actual engineering project and calculates the power frequency earthing resistance from the viewpoint of engineering calculation based on the international code BS 7430:2011. The practice proves that the calculation of power frequency earthing resistance in actual projects is of more explicit guidance to the design of the earthing system.
