《高压阀式避雷器》 第二章 阀式避雷器的非线性电阻 附视频

Dianci bileiqi, 1975
2—1 非线性电阻的一般概念非线性电阻是一种固体半导体制品,当施加的电压升高时,它的电阻实际上无时延地降低。非线性电阻分为两类。在称为压敏电阻的电阻中,电流密度为10-6～1安/厘米2数量级。这种电阻可以长期施加电压,负载主要受发热和散热限制。第二种非线性电阻主要是用于短时大负载的电阻。阀式避雷器和其它过电压保护装置中的电阻以及高压电器用大功率分路电阻都属于这一类。这类电阻能承受时间10-5～10-1秒的短时负载。其电流密度和电位梯度能分别达到10～2～10～3安/厘米2和2—4千伏/厘米 ...
