摘要:
GIS在开关分闸后母线上会存在幅值较高的残余直流电压,由于GIS中电荷泄漏较慢,残余直流电压可持续作用较长时间。当再一次合GIS母线时,母线上可能会出现冲击过电压,冲击过电压会与母线残余直流电压叠加,使GIS处于直流叠加冲击电压的作用下。近年来国内多起GIS击穿事故发生于开关合闸瞬间,因此有必要对直流叠加冲击电压下GIS的放电特性进行研究。首先介绍了直流叠加冲击电压下稍不均匀电场和极不均匀电场中SF6气体间隙的放电特性和放电机理,以及直流叠加冲击电压下自由金属微粒引起的气体间隙放电特性;然后总结了直流叠加冲击电压下绝缘子沿面的闪络特性和金属微粒对直流叠加冲击电压下绝缘子闪络特性的影响,并分析了表面电荷对绝缘子沿面闪络过程影响机理的研究现状;最后,总结了目前研究中存在的问题及未来的研究方向。通过对目前国内、外直流叠加冲击电压下GIS放电特性的研究,以期对工程建设和学术研究起到参考作用。
Abstract:
There will be residual DC voltage on the bus of GIS equipment after the circuit breaker and disconnector are opened. Due to the low leakage velocity in GIS, the residual DC voltage can remain for several hours. When the switch is re-closed, an operating overvoltage will be generated. The overvoltage will be superimposed on the residual DC voltage existing in the bus, putting GIS under combined voltage of DC and impulse. Many domestic accidents of GIS occurred at the moment of switch closing, so it is necessary to study the discharge characteristics of GIS under combined voltage of DC and impulse. In order to clarify the current research status and to serve as reference in engineering and academic research, this paper summarizes the research on the discharge characteristics of GIS under combined voltage of DC and impulse at home and abroad. First, the discharge characteristics and discharge mechanism of SF6 gas gap in quasi-uniform electric field and nonuniform electric field under combined voltage of DC and impulse are introduced, as well as the discharge characteristics caused by the free metal particles; Then the flashover characteristics of insulators under combined voltage of DC and impulse and the influence of metal particles on the flashover characteristics of insulators are summarized, and the research status of the influence mechanism of surface charge on the flashover process of insulators is analyzed. Finally, the existing problems and future research directions are summarized.
