摘要:
雷击是造成输电线路发生跳闸和停运事故的主要原因。“防雷在于接地”,对输电线路的接地网的冲击接地特性进行研究改进对于防止雷击事故有着不可或缺作用。本文在不考虑火花放电效应和考虑火花放电效应两方面对钢、铜、石墨复合接地材料的接地网冲击接地阻抗进行对比分析。同时,采用ATP-EMTP建立了考虑火花效应时的接地散流模型,研究了土壤电阻率、接地网面积及冲击电流幅值对接地网冲击接地特性的影响。研究结果表明:考虑火花放电效应时,接地材料的冲击接地阻抗相比不考虑火花放电有所降低。不同接地材料冲击接地阻抗同时受火花放电效应与电感效应的影响,二者的强弱关系与冲击电流的幅值有明显关系。相对于传统金属接地材料,石墨复合接地材料冲击接低阻抗小。
Abstract:
According to statistics, lightning strike is the main cause of transmission line trips and outage accidents. “Lightning protection lies in grounding.” Research and improvement on the grounding network's impact grounding characteristics of transmission lines are indispensable for preventing lightning accidents. By not considering the spark discharge effect and considering of the spark discharge effect, this article compares and analyzes the impact grounding impedance of steel, copper and graphite composite grounding materials. Considering the spark effect, using ATP-EMTP to establish the circuit model, the effects of soil resistivity, grounding grid area, and impact current amplitude on the impact grounding characteristics of the grounding grid were studied. The results show that when considering the spark discharge effect, the impact grounding impedance of the grounding material is lower than that without considering the spark discharge. The impact grounding impedance of different materials is affected by both spark discharge effect and inductance effect. Compared with traditional metal grounding materials, graphite composite grounding materials have low impact resistance.
