Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below according to the drawings and embodiments. It should be understood that the specific implementations described here are only used to explain the present invention, not to limit the present invention.

[0021] In actual production and life, when a component is subjected to different voltage shocks, the number of times it can withstand shocks is not the same. If we only count once for each voltage shock (lightning strike or surge voltage), it is inevitable It is impossible to accurately predict the life cycle of components. For example, a varistor can withstand 4000V lightning strikes 10 times, but it may only withstand 6000V lightning strikes 5 times. In this regard, the lightning protection device of the present invention and the method for counting the number of times of lightning strikes are proposed to count...

Abstract

The invention provides a lighting prevention device and a method for counting the number of lightning strokes on a lighting prevention device. The lighting prevention device comprises a lighting prevention component, a lightning stroke counting module and a network management server. The lighting prevention component is used for preventing external devices (such as network devices) connected with the lighting prevention device from damage caused by the lighting strokes. The lightning stroke counting module is connected with the lighting prevention component, measures voltage values of the lighting prevention component subjected to the lighting strokes or surges, adds up the number of voltage surge according to the voltage values of the lighting prevention component subjected to the lighting strokes or surges and a preset counting rule, and transmits an alarm signal to the network management server when the stored sum of the voltage surge is larger than the preset threshold value. The network management server can represent the alarm signal and transmit the alarm signal to device maintenance personnel, and then, the device maintenance personnel can maintain and replace the component in the lighting prevention device.

Description

technical field [0001] The invention relates to the technical field of lightning protection, in particular to lightning protection equipment and a method for counting times of lightning strikes. Background technique [0002] In real life, it is very common for lightning to damage electronic equipment. For network equipment on the trunk line, lightning protection is a necessary condition to ensure the normal operation of the entire network. [0003] At present, many lightning protection devices use piezoresistors to protect against lightning, but piezoresistors have a lifespan. Generally, after five lightning strikes, they will lose their lightning protection function. It may be damaged and cannot play the role of lightning protection. [0004] When the network equipment fails, the equipment maintenance personnel will replace or repair each network equipment and its lightning protection device. On the one hand, this will cause a lot of trouble to the user, and it is easy for...
