摘要
高压电能表是配电网新型高压电能计量产品,克服了现有配电网高压计量装置组件复杂的弊端。而供电单元的设计是高压电能表设计的重中之重。本文中介绍了高压电能表的基本结构,简要分析了现有的供电单元设计技术的问题,提出了用"电容、电阻限流降压电路"取代"电容分压器"一种新的高压电能表供电单元解决方案。
High voltage electric energy meter is a new type of electric energy metering product in distribution network,which overcomes the disadvantages of the high voltage measurement equipment's complex structure in the distribution network. The power supply unit is the most important part in the design of high voltage electric energy meter. This paper introduces the basic structure of the high voltage electric energy meter,analyzes the problems existing in the design of the power supply unit. This paper presents a new solution for the high voltage power meter power supply unit,which uses " capacitor,resistor current limiting circuit" instead of"capacitor voltage divider".
