摘　　要：随着电网容量的增大,故障时经地网流散的电流愈来愈大,短路电流可达几万安培。接地网的可靠是电网安全运行的重要措施,降低接地电阻,改善土壤结构,能够提高接地网的运行可靠性。从接地网运行环境分析入手,结合太钢东山石灰窑35 kV变电站实例,阐述了影响接地网接地电阻的因素,研究了山地岩石地区的变电站接地系统的设计和应用。With the increase of network capacity,the current dissipated by ground grid is getting larger and larger in the case of fault,short-circuit current may reach to tens of thousands of Amperes.The reliable ground grid is an important measure for safety operation,therefore reliability of grounding grid can be improved by reducing grounding resistance and improving soil structure.This article explains factors affecting grounding resistance of grid by introducing of grounding running environment analysis in combination with the case of TISCO 35kV Dongshan lime kiln substation.This paper studies the design and application of substation grounding system in mountainous and rocky areas.
