智能电表电应力可靠性试验平台的设计

智能电表作为智能电网的核心部件,其种类多、数量大、覆盖面广,但故障率一直在上升,维护性工作不断增加。故文章模拟现场运行条件,设计了一种智能电表电应力可靠性试验平台,该平台可以模拟电网过压、工频过压、欠压等多种电应力以及实负载运行,能够通过长期运行提前发现电能表故障,解决了现场检验工作一直存在的矛盾。

As the core component of smart grid,smart meter has many kinds,large quantity and wide coverage,but the failure rate has been rising and the maintenance work has been increasing.Therefore,this paper simulates the field operation conditions,and designs a kind of intelligent meter electrical stress reliability test platform,which can simulate many kinds of electric stress and real load operation,such as overvoltage,power frequency overvoltage,undervoltage and so on.The fault of watt-hour meter can be found in advance through long-term operation,which solves the contradiction that has always existed in the field inspection work.
