多用户智能电能表自身功耗及其功能特点

Power Consumption,Functions and Features of Multi User Smart Watt-hour Meter

电能表由于用量大且长期连续工作,其耗电不可忽视。根据计量部门提供的型式检验报告,对各类电能表的自身能耗进行了比较。现有单户电能表功耗多在1W以上,虽满足国家标准,但从节能角度考虑,还应尽量减少其功耗。多用户智能电能表,其平均每户自身功耗不到0.3W,每户年节电约10度,规模效益十分巨大。在能源日趋紧张的环境下,多用户智能电能表具有较高的应用价值和重要的现实意义。多用户智能电能表非常适合我国国情,其功能也很完善,国家应支持和鼓励多用户智能电能表的发展。

The power consumption of watt-hour meter couldn't beneglected because of large consumption and long term uninterrupted running. According to the type test reports provided by the measurement department, we make a comparison on the energy consumption of various watt-hour meters.We find that the power consumptions of most of the existing single user watt-hour meters are more than 1W. Though they meet the demand of the National Standard, we should minimize its power consumption out of consideration of energy saving. Multiuser smart watt-hour meter which average power consumption is less than 0.3W,and energy saved per year is 10 kilowatt-hours per user, has a very large scale benefit. During energy crisis, multi user smart watt-hour meter has high application value and great practical significance.So our country should support and encourge the development of multi user smart watt-hour meter,because the meter is suitable for our national condition extremely and it 's function is also perfect.
