考虑现场校验的智能电能表可靠性分析与改进

为解决智能电能表运行8年到期轮换的问题,列举并分析了3种可行的电能表轮换方案。随着智能电能表生产水平的提高,针对采用现场校验方式延长电能表轮换周期的方案,考虑不同地域的气候因素和电能表现场校验结果的影响,对基于威布尔分布分析电能表运行寿命的过程进行修正,通过理论计算与实际情况对比验证该方法可行,为电能表轮换周期的延长提供理论依据。

Reliability Analysis and Improvement of Smart Electric Energy Meter Considering Field Verification

In order to solve the problem of 8-year expiration replacement of smart electric energy meters, three schemes for electric energy meter replacement are introduced and analyzed. The improvement of the production level of smart energy meters has provided a necessary basis for extending the replacement period of electric energy meters. In view of the scheme of extending the replacement period with field verification method, a correction is made of the operation life process of the electric energy meter based on Weibull distribution analysis considering the climatic factors of different regions and the influence of the field verification result of the electric energy meters. The theoretical analysis and actual application have proved the feasibility of the proposed method, which will provide a reference for extending the replacement period of the smart electric meters.
