中文摘要:

π形接线是客户35kV及以上受电工程中常用的一种电源引入形式,该接线建设资金少,周期短,即可满足客户供电的可靠性要求,又保持了电网运行方式的灵活性。但就一般设计中的电能计量而言,存在客户计费上无法克服的计量缺陷。本文针对该缺陷进行了详细分析,并通过二次回路改造的方式,提出了具体的解决方案,对电能计量的现场工作,有实际的参考价值。

英文摘要:

π-junction is a 35kV and above customer power supply form used in electrical engineering.The wiring construction capital is little,cycle is short,which can meet the reliability requirements of customer power,and maintain the flexibility of power grid operation mode.But the general design of the electric energy measurement is unable to overcome measurement of defects on the customer billing.This paper carries out a detailed analysis on the defects,and puts forward the specific solution through the transformation of the secondary circuit.
