针对电涌抑制晶闸管(TSS)在雷电过电压作用下残压、通流及吸收能量的问题。通过对TSS的结构和原理分析,利用组合波发生器模拟雷电过电压,研究不同幅值的雷电过电压作用下TSS的冲击性能,分析TSS两端残压、通流及其吸收能量的变化趋势。得出:在TSS两端施加的冲击电压越大,其残压、通流值及吸收能量越高;TSS的吸收能量与冲击电压有一定的函数关系,但是当TSS的额定击穿电压达到275V及以上时,其吸收能量与冲击电压由幂函数关系变为线性函数关系。为TSS在实际应用中提供理论依据和参考。
Surge suppression thyristor (TSS) in the lightning under voltage over-voltage, flow and absorption of energy issues. By analyzing the structure and principle of TSS, the combined wave generator was used to simulate the over-voltage of lightning and the impact performance of TSS under different amplitudes of lightning over-voltage was studied. The variation trend of residual voltage, flow and absorbed energy at both ends of TSS . The results show that the larger the impulse voltage applied at both ends of TSS is, the higher the residual voltage, the through current and the absorbed energy are. The energy absorption of TSS has a certain function as the impulse voltage. However, when the rated breakdown voltage of TSS reaches 275V And above, the absorption energy and the impact voltage changes from a power function to a linear function. In order to provide theoretical basis and reference for TSS in practical application.
