摘　　要：随着柱式开关、环网柜等一二次融合配电开关设备的推广应用,对配电开关设备入网检测方案和关键影响因素分析需求迫切。文中根据一二次融合配电开关设备的结构组成原理,分析环境温度、电磁干扰和局部放电等因素对一二次融合设备可靠性和准确性的影响原因。利用高低温环境模拟箱、雷电冲击发生装置和局放测试仪等设备实验研究上述因素对配电开关一二次融合影响规律,提出串联滤波电路用于提高设备的抗强电磁干扰能力,降低了互感器输入端高频干扰的影响,为配电开关一二次融合入网检测和关键指标考核提供参考。With the popularization and application of such primary and secondary integration distribution switchgear as column switch and ring main unit,it is urgent to analyze the network access detection scheme and key influencing factors of distribution switchgear.Based on the structure and working principle of the primary and secondary integra⁃tion distribution switchgear in this paper,the influence of such factors as ambient temperature、electromagnetic inter⁃ference and partial discharge on reliability and accuracy of the primary and secondary integration equipment is ana⁃lyzed.Such test equipment as high and low temperature environment simulation box,lightning impulse generator and partial discharge detector are used to study the influence of above factors on the primary and secondary integration of distribution switchgear.The series filter circuit is proposed to improve the ability of the equipment to resist strong electromagnetic interference,reduce the influence of high frequency interference of the input end of instrument transformer,and provide reference for the network access detection and primary and secondary integration distribu⁃tion switchgear as well as key index assessment.
