Embodiment Construction

[0047] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0048] Please refer to FIG. 1 , which is a schematic structural diagram of a system for monitoring surge protectors according to the present invention. It includes a terminal monitoring device 1 and at least one surge protector (hereinafter referred to as SPD) 2 to be monitored. Each SPD2 communicates with the terminal monitoring device 1 through the power line, and each SPD2 will indicate that the local SPD body is working The working status data of the status or surge status are transmitted to the terminal monitoring device 1 through the original power supply and distribution line, so as to realize the remote monitoring and control of the SPD2. The monitoring system of the present invention can realize the monitoring of several SPDs 2 by one terminal monitoring device 1, thereby achieving the purpose of centralized monitoring.

[0049] Please refer to FIG. 2 , whi...

Abstract

The invention is concerned with the monitoring system of the current rush protector, includes the terminal monitoring equipment and the SPD demands to be monitored at least one, which can communicate with the terminal monitoring equipment through the electric power line. It works as: the terminal monitoring equipment sends out the scanning single following standard timing or special request, and through the second signal send/receive device to the power supply circuit, reaches the scan signal receiving SPD, when inspecting right overpasses, it can send the working state to the power supply circuit to the terminal monitoring equipment. Even there is abnormity of the SPD, it can send the abnormity data to the power supply circuit automatically, for intermit requesting and the terminal monitoring equipment can determine to report or intermit the circuit by analyzing the SPD data. The SPD is also with the capability of intermitting.

Description

technical field [0001] The present invention relates to a surge protector, in particular to a system and a corresponding method for monitoring a surge protector based on a power distribution line. Background technique [0002] A surge protector (Surge Protective Device, SPD) is a device used to limit transient overvoltage and guide surge current, and it includes at least one nonlinear element. Because it not only has the function of lightning protection, but also has the function of suppressing switching overvoltage, SPD is widely used in many fields, such as the field of meteorological disaster warning. [0003] When a surge occurs, the SPD will reduce the overvoltage of the protected equipment to below the rated value of the equipment's impact overvoltage resistance through its own characteristics of limiting transient overvoltage and diverting surge current. However, when the surge voltage exceeds the maximum withstand capacity and discharge current capacity of the SPD d...
