Abstract

The invention discloses an intelligent SPD system based on a power line carrier technology. The system comprises an intelligent SPD, an SPD information interaction management device and an SPD intelligent supervision early warning host. The information data collection management module is respectively in signal connection with the current intensity monitor, the lightning stroke frequency monitor, the leakage current inductor, the lightning polarity monitor and the thermal unhooking inductor to collect each group of data. The information data collection management module is in signal connection with the information data storage module and is used for storing each group of acquired data into the information data storage module. The information data collection management module is in signal connection with the wireless communication module and is used for transmitting collected data to the Internet of Things, and the information data collection management module is in signal connection with the power line carrier data interaction module and is used for transmitting the collected data to the SPD intelligent supervision early warning host through a power line carrier technology so as to realize remote data monitoring. The intelligent SPD system has the advantages of remotely monitoring the SPD state and reducing the accident rate and the maintenance cost, and is mainly used for SPD intelligent monitoring.

Description

technical field [0001] The invention belongs to the field of SDP application technology, in particular to an intelligent SPD system based on power carrier technology. Background technique [0002] SPD (surge protective device) is a device used to limit transient overvoltage and discharge surge current. SPD technology is an indispensable measure for buildings to realize lightning protection and operating overvoltage protection. [0003] Ordinary SPDs have some hidden dangers due to their own characteristics. For example, the capacity of ordinary SPDs is limited, and high temperature, high heat, and even explosion and fire will occur if the capacity exceeds the capacity; its lifespan will gradually decrease. As the capacity keeps decreasing, the SPD will gradually heat up. At this time, if it encounters a large lightning shock, it will fail instantly, or even explode and cause a fire; if the failed module is not found and replaced in time, the protected device will be in an u...
