摘要
依据气体放电管与TSS配合使用原理,借助电力试验研究院雷电流冲击平台,采用组合波发生器(8/20μs,1. 2/50μs)对气体放电管和TSS的配合使用电路进行冲击试验。主要研究级间电阻对气体放电管和TSS管通流、残压影响的变化趋势,以及不同型号TSS管对气体放电管和TSS管通流、残压的影响。研究得出:TSS管通流随着级间阻值的增加而减小,而GDT通流与电阻无关;同时得出不同型号TSS管对气体放电管和TSS管通流没有影响,且TSS管压越大,TSS残压值越大,GDT的残压随冲击电压总体呈逐渐上升趋势。气体放电管与配合使用电路中,冲击电压在超过盲区到1. 0 k V左右范围中,配合电路发挥作用较大。
Based on the principle of gas discharge tube and TSS,the impulse test is carried out by using the combined wave generator( 8/20 μs,1. 2/50 μs) to test the circuit of gas discharge tube and TSS.The influence of interstage resistance on the current and residual voltage of gas discharge tube and TSS is analyzed. Study has also been made to see whether the different types of TSS will influence the current and residual voltage of gas discharge tubes. It is concluded that the current of TSS decreases with the increase of interstage resistance,and the flow of GDT is independent of resistance. At the same time,it is concluded that the type of TSS has no effect on the current of gas discharge tube,and the higher the TSS tube pressure,the greater the TSS residual voltage. The residual voltage of GDT increases with the impulse voltage. The coordination circuit plays a more import role when the impulse voltage is in the range of 1. 0 kV,beyond the blind area.
