摘要
阐述了某铝冶炼企业用电量高的原因之一是进线电能计量系统误差大,提出了选用高精度的电能表、增大进线电能表PT二次导线载面等解决办法.部分实施后,用电量每年降低1 600万kW·h.
The article described one of the reason which amount of electricity consumed is high in an aluminium smelting enterprise is large error of electrical energy meter. Proposed the way of using high accuracy electrical energy meter and increasing second wire setion of PT to solve the metering accuracy. After implimentaion, the amount of electricity consumed decreased 1 600 kW·h.
