Abstract

The invention relates to a lightning-protection fuse with reliable alarm and an overvoltage surge protection device thereof, belonging to a surge protector product. The lightning-protection fuse comprises an insulated tube, an electrode A, a wiring terminal of an electrode B, a metal bar, a compression spring and a triggering device. The overvoltage surge protection device using the lightning-protection fuse comprises the lightning-protection fuse with reliable alarm, a piezoresistor and two pins and can also be in the other structure, comprising the lightning-protection fuse with reliable alarm, the piezoresistor, a gas discharge tube and two pins. The surge overvoltage protection device has the benefits advantages that when the piezoresistor has a short circuit and overhigh temperatureraise, the overvoltage surge protection device designed by the piezoresistor can be reliably divorced separated from the conductive connection with a power supply system to prevent the conductive connection from resulting in fire accidents; and the overvoltage surge protection device designed by the piezoresistor removes eliminates a failure mode that the piezoresistor is explored by overlarge pulse current to cause the lightning-protection fuse to not alarm.

Description

technical field [0001] The present invention relates to surge protector products, more specifically, relates to a device that reliably cuts off the power supply to prevent fires caused by the short circuit of the varistor when the zinc oxide varistor short circuit fails, and at the same time gives an alarm signal A lightning protection fuse and a surge overvoltage protection device designed using the lightning protection fuse. It is widely used in surge overvoltage protection of power supply equipment, electrical equipment, power grid system and communication station, etc. Background technique [0002] In order to prevent the surge overvoltage generated by lightning strikes from damaging power supply equipment, electrical equipment, power grid systems, and communication stations, lightning protection devices, namely surge protection devices, or SPDs, are generally installed. [0003] The power surge protection device SPD in the prior art is mainly composed of components suc...
