梧州市郊低压三相电能计量装置的误差分析及整改措施

Error Analysis and Transformation of LV Three-phase Energy Metering Device in the Suburb of Wuzhou

电能是一种商品,电能计量装置则是一把秤,它的准确与否,直接关系到供用电双方的经济利益。所以,应该最大限度降低电能计量装置综合误差,做到公正合理计费。梧州市郊现有各类用户2万多户,部分电能计量装置特别是三相电能计量装置由于设计、配置、选型和施工时不规范,影响了计量准确度,给电力企业造成了一定的经济损失。因此,分析三相计量装置误差产生的原因,改进计量装置配置意义重大。文章以梧州市郊某些低压计量点为例,分析产生误差的主要原因并提出改进措施。

The accuracy of energy metering device directly concerns the economic benefit of the power supplier and the customer.Therefore,the composite error of the device shall be minimized in order to charge in a fair and reasonable manner.There are over 20,000 households in the suburb of Wuzhou.Some energy metering devices,especially three-phase ones are not so accurate due to nonstandard design,configuration,type selection and assembly,resulting in economic loss of electric power enterprises.Therefore,it is important to find out the cause and improve metering devices.This article studies the main reasons of error and proposes measures for improvement by taking LV metering points in the suburb of Wuzhou as example.
