摘要： The disclosure describes a surge protection device that makes use of metal oxide varistors (MOVs) to limit the magnitude of electrical surges in single phase or multi-phase power distribution networks. Since MOVs generally fail in a low impedance mode when the electrical ratings of the devices are exceeded, current limiting and thermal limiting devices are connected in series with the MOVs to limit the effect of these failures to the surge protection devices. The physical configuration of the surge protection device limits the effects of a current limiter being activated by providing a barrier between the current limiter and the associated MOV. Filler material is also used to limit the effects of debris or plasma gas from an activated current limiter. Multiple surge protection devices may be connected in parallel to provide increased current handling capability, and visual indication of a failed surge protection device may be provided.
摘要翻译：本公开描述了一种使用金属氧化物变阻器（MOV）来限制单相或多相配电网络中的电涌的大小的浪涌保护装置。由于当超过器件的额定电流时，MOV通常在低阻抗模式下失效，限流和限流器件与MOV串联，以限制这些故障对浪涌保护器件的影响。浪涌保护装置的物理配置通过在限流器和相关的MOV之间提供屏障来限制正在激活的限流器的影响。填充材料也用于限制来自激活的限流器的碎屑或等离子体气体的影响。多个浪涌保护装置可以并联连接以提供增加的电流处理能力，并且可以提供故障浪涌保护装置的视觉指示。

摘要： A transient voltage surge suppression system incorporating a current protection device comprised of a voltage sensitive and a thermal sensitive device. The voltage sensitive device has a predetermined voltage rating and increases in temperature as voltage applied thereto exceeds its voltage rating. The thermal sensitive device is responsive to heating of the voltage sensitive device to break an electrical current path if an overvoltage condition sensed by the voltage sensitive device exceeds the voltage rating of the voltage sensitive device.
