摘要

针对主动型过电压保护间隙(SPG)研究中仅从触发回路的结构及材料角度难以分析其性能差异的机理

通过建立组合波注入下触发回路的等效模型

获得了触发回路输出电压的暂态解析式。基于触发回路的电压动作过程、触发电流与主间隙电流的数值关系、发生时序的理论分析及实验验证

得出了触发回路响应时间及保护间隙击穿电压的变化规律。研究发现:触发回路中耦合气体放电管动作滞后于压敏电阻

Abstract

To overcome the difficulties in analyzing the mechanism of performance differences among the active surge protection gaps(SPG)by merely changing the structures or materials of trigger circuits

an output voltage transient formula of the trigger circuit is obtained by establishing an equivalent model of the trigger circuit under combined wave. On the basis of the quantitative analysis and experiment

the trigger circuit dynamic voltage changing sequences

the numerical relationship and action series between the trigger current and main gap current

the response time of the trigger circuit

and th

e voltage changing regularities of SPG are obtained. It is found that: the coupled gas discharge tube in the trigger circuit lag acts behind the varistors; the voltage of main gap approximately reaches the sum of threshold voltage of varistor U

1 mA

and gas discharge tube action voltage U

while gas discharge tube acts; the trigger current I

appears before main gap current I

but is much smaller than I

; the response time of the coupled gas discharge tube t

and the trigger gap t

decrease with the increasing impulse peak voltage; and the response time t

and the voltage ratio K of the active SPG are far less than the values 2 μs and 2.42 of the passive SPG.
