壓敏電阻器與氣體放電管配合使用的主要特性探析

摘要：本文簡述了壓敏電阻器與氣體放電管相互之間的配合使用。從保護可靠性的角度分析，采用兩者有效的配合使用，不但可以提高泄放暫態過電壓的能力，減緩壓敏電阻器的性能劣化。而且為降低壓敏電阻器在大幅值8/20電流波沖擊時，殘壓過高提供了有力依據。 敘詞：壓敏電阻器 氣體放電管 配合使用 Abstract：This article summarized has pressed sensitive resistor and the gaseoustube mutually between coordinate use. From protection reliable angle analysis: Uses two effective coordinate uses, This will not only improve transient over-voltage discharge capacity, Slow varistors performance degradation; But to reduce varistors dramatically in value 8/20 current wave of attacks, Residual voltage too high to provide a strong basis.　 Keyword：Varistors, Gas discharge, Used in conjunction with
