摘　　要：窃电不仅有损用户及供电公司的利益,还会干扰电网的正常运行,故需对防窃电方法进行研究。根据某电能表采样电路工作原理,分析窃电工况下电量计算及差错电量核算等问题,推导得出相应的防窃电方法。试验测定了电能表的基本误差,将其与累计电能做比较,发现理论数据与试验验证数据一致,能够精准、迅速地核算出差错电量,可有效防窃电。Power theft not only harms the interests of users and power supply companies,but also interferes with the normal operation of the power grid.So it is necessary to study the methods of preventing power theft.According to the working principle of sampling circuit of an electricity meter,the study analyzes the calculation of electric quantity and error electric quantity under the condition of electric stealing,and deduces the corresponding anti-electric theft method.The basic error of the watt-hour meter is measured by experiment,and compared with the accumulated electric energy.It is found that the theoretical data is consistent with the experimental verification data,which can accurately and quickly calculate the wrong amount of electricity,and effectively prevent electricity theft.
