Abstract:

弧后介质热恢复特性对断路器开断能力有着显著的影响,该文旨在通过实验手段研究不同因素对高压气体断路器弧后电流特性的影响。首先以126kVSF6断路器为原型设计了实验样机,之后在不同触头分开时电流相位θ(20°、50°、80°),预期短路电流值I(12、18kA)及腔体充气压力P(0.5、0.6及0.7MPa)下进行了一系列开断实验,利用高分辨率的零区设备采集零区电弧电流。结果表明:间隙电弧重燃概率随θ增加而增大,当I=18kA且P=0.5MPa时,θ为20°时间隙未发生击穿,而θ分别为50°和80°时弧隙击穿且弧后电流的上升速率分别为1.03和2.08A/μs;弧后电流及其上升速率随I的增大而增加,当θ=80°且P=0.6MPa,I为12、18kA时所对应的弧后电流上升速率分别为1和2.05A/μs;当θ=80°且I=12kA时,弧后剩余电流随着P的增大趋向于减小。气体的热开断能力与临界弧后电流存在对应关系,一定程度上可以考虑将弧后电流的临界值作为弧后热击穿的判据。
