【摘要】 研制了一种200kV/100kA环轨式场畸变开关。对该开关以Ar,N2,SF6及SF6/N2,SF6/Ar混合气为工作介质的耐压及触发性能研究结果表明:该开关耐压最大偏差小于自击穿电击的4%;欠压比大于等于自击穿电击的80%时,抖动极差小于2ns,标准方差抖动小于等于1ns;实现了多通道导通,通道数大于等于3;开关工作范围极大,在欠压比大于等于自击穿电击的20%时抖动极差小于2.85ns。更多还原

【Abstract】 This paper reported the results of the investigation of a 200kV/100kA low jtter low prefire probability ring rail field distortion switch. Its jitter was less than 2 ns when its working voltage was larger than 70% of selfbreakdown voltage. When its working voltage was greater than 85% of selfbreakdown voltage its jitter was less than 1ns if the mixture of Ar, N2 and SF6N2, SF6Ar in which the percentage of SF6 was less than 50% was used as dielectric. Its maxium derivation of selfbreakdown voltage was less than 4% of selfbreakdown voltage. It is a multichannel switch and the number of discharging channel was more than 3. The results of selfbreakdown and triggering experiments working with Ar, N2, SF6 and SF6N2, SF6Ar mixtures were introduced.更多还原
