摘要
文章按照地网均压理论,设计出不等间距均压接地网;经对地网参数的计算及实际测试验证,发现了相关标准中个别系数有误;通过实际测试,证明了均压接地网的均压效果非常显著,各网孔电势大致相等,各网孔电势与平均值相差不超过2.67%,最大网孔接触电压差是长孔或方孔网的40%左右;能够很好地满足规程对于接触电位差、最大跨步电位差等安全指标的要求。
The paper designs an unequal interval voltage-sharing ground network based on the ground network voltage-sharing theory. Through pratical test and calculation of the ground network parame- ter,some individual factors are found wrong. The practical test proves that the voltage-sharing effect of voltage-sharing ground network is very significant. The nets mesh potential are roughly the same, the difference between mesh potential and average potential is less than 2.67%, and the maximum mesh contact voltage difference is lower than that of sol the requirement of the regulations is well met in ence and the maximum step potential difference. long mesh or square mesh network about 40 % or safety indicators such as contact potential differ-
