浪涌保护设备
摘要：
电路保护设备(100)包括金属氧化物变阻器(MOV)(35)、弹簧端子(36)和将弹簧端子(36)耦合到MOV(35)的热断开器(30d)。气体放电管(GDT)(50)耦合到MOV(35)。弹簧端子(36)被偏置，使得，在发生过电压状况时，由MOV(35)生成的热量熔化热断开器(30d)并允许弹簧端子(36)从MOV(35)移位，由此产生开路。
摘要（英）：

A circuit protection device includes a metal oxide varistor (MOV), a spring terminal and a thermal disconnect coupling the spring terminal to the MOV. A gas discharge tube (GDT) is coupled to the MOV. The spring terminal is biased such that upon occurrence of an overvoltage condition, heat generated by the MOV melts the thermal disconnect and allows the spring terminal to be displaced away from the MOV, thereby creating an opening circuit.
