| 摘 要： | 为寻求煤矿电力系统防雷方法,首先介绍煤矿电力系统的特点及其雷电防护的重要性。根据35k V进线特点,建议使用保护角法对线路保护,并对布线方式和避雷线的设置提出建议。通过对雷电流和电力杆塔自身特性的分析、计算提出了相应的防护措施。提出煤矿变电所应当进行防雷类别划分,并根据变电所区域防雷保护对象的特点,计算"滚球法"和"折线法"的保护范围,经过对比,提出不同高度避雷针保护范围的计算方法。最后对安全距离、SPD设置等煤矿电力系统防雷的其它问题进行了说明。

| Abstract: | In oder to explore the method of lightning protection for coal mine, the paper introduces the characteristics of coal mine electric power system and the importance of lightning protection. According the characteristic of 35kV put forward the wire method of protective angle for the wire. And puts forward some suggestions to the wiring mode and the settings lightning line. Puting forward corresponding protective measures through analysis the characteristic of lightning current and power pole. Put forward coal mine substation shall be classified for lightning protection. Selection"rolling ball method" or the broken line method scope of protection calculation according to the characteristics of lightning protection object of substation area. Presents the calculation methodSof different height ofSthe protective range of lightning rodSby comparison. At the end other problems are described of mine power system such as the safety distance and SPD settings. |
