摘要
针对目前电能表出现时钟电池欠压问题,分析电能表的内部原理,通过电能表检定装置对时钟电池欠压的电能表进行计量误差检测,而且在电池欠压情况下测试电能表的时钟波形,并进行停电实验。通过实验确定了时钟电池欠压不会影响计量误差,但是在停电时电池欠压会影响电能表时间的准确性,从而造成多费率电表中的电能计费出现错误。为了解决该问题,从硬件和软件方面给出了设计方案。
In the light of the undervoltage of the clock battery in power meter, with the internal principle analyzing, the metering error is tested through the verification device on the condition that there is an undervoltage of the clock battery of power meter. Besides, the waveform of the clock is also detected and the experiment of power failure is carried out. Based on the tests, it's concluded that the metering error will not be influenced by the undervoltage. However, the accuracy of the time will be affected and it results in an error in the energy billing of multi-rate power meter. To solve the problem, the design proposal both hardware and software are prolapsed respectivelv.
