| 摘 要： | 无线二次核相仪器的使用显著缩减了人力和时间,但在智能分析方面存在不足。针对电压回路接线错误时无法为作业人员提供指导的问题。通过汇总某相线和中性线接错、两相线接错、三相全部接错的3类典型错误,提出了对采样数据按照幅值、对称性、相序和相位4个环节开展递进式的智能分析方法,各环节反馈的信息可为作业人员消缺提供指导。

| Abstract: | The use of wireless secondary phase detector significantly reduces the manpower and time,but it is insufficient in intelligent analysis.The instrument cannot provide effective guidance for staff in error situations.This paper summarizes three kinds of typical errors including wrong connection of phase line and neutral line,two phase lines and three phase line.This paper presents a progressive intelligent method for the sampled data according to the amplitude,symmetry,phase sequence and phase.The feedback information of each link can provide guidance for operators. |
