Intelligent SPD (Surge Protective Device) monitoring system

Abstract

The invention provides an intelligent SPD (Surge Protective Device) monitoring system, which is characterized by comprising a server, data acquisition terminals, intelligent SPD modules, transmission lines and communication modules, wherein the server comprises a communication port, an input panel, a processor and a display panel; each data acquisition terminal comprises a communication port, a single-chip microcomputer and an input and display module. According to the intelligent SPD monitoring system capable of acquiring, counting and analyzing surge events in lines, lightning stroke information recorded by each intelligent SPD module in the lines is acquired, and related information in each line and each phase line is transmitted to the acquirers and the server to be counted and analyzed to judge whether the surge events occurs to the related lines or not and whether the corresponding intelligent SPD modules are required to be timely replaced or not by virtue of a power line carrier technology; the SPD modules are connected to a power supply system or a communication system to protect indirect lightning and direct lightning influence or other transient overvoltage surge.

Description

technical field [0001] The invention belongs to the field of electric circuit protection equipment, and in particular relates to an intelligent SPD monitoring system for collecting relevant information of surge protectors in lines. Background technique [0002] With the popularization of computer information technology, the use of information-based electronic equipment is becoming more and more extensive. Due to the high integration of electronic equipment, it often has the characteristics of low operating voltage and high sensitivity. Electronic equipment widely used today Memory is harmed by lightning electromagnetic pulse. [0003] Installing a surge protector (SPD) is an important measure to protect electrical equipment from electromagnetic pulse shocks. However, due to the suddenness and unpredictability of power surges, current SPDs often have the following problems: [0004] 1. It is difficult to monitor the operation status of SPD equipment, and it is difficult to ...

AI Technical Summary

Problems solved by technology

[0004] 1. It is difficult to monitor the operation status of SPD equipment, and it is difficult to monitor whether the SPD is working normally or not in real time;

[0005] 2. When a power surge occurs, it is not sure whether the SPD can play a role;

[0006] 3. After multiple power surges, whether the SPD deteriorates and the degree of deterioration is unknown, so it is impossible to replace the deteriorated SPD in time;

[0007] 4. The installation points of SPD are relatively scattered, and the inspection, evaluation and maintenance are time-consuming and labor-intensive, and the cost is high
