Problems solved by technology

[0013] The purpose of the present invention is to provide a surge protector with a self-monitoring function to solve the problem that the prior art cannot monitor and store the working state of the SPD in real time, so as to cut off the power supply of the SPD in time when the SPD fails or fails, and then protects the surge protector. Protected equipment, so as to avoid technical problems in major events such as fire, and provide accurate judgment basis for insurance compensation in case of lightning damage

Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] see figure 1 , which is a schematic diagram of the structure and principle of the SPD of the present invention. The SPD of the present invention includes a SPD body 21 , a signal collector 22 , a signal converter 23 connected to the signal collector 22 , a processor 24 , a storage unit 25 , an input device 26 , an output device 27 and an alarm device 28 .

[0038] The SPD body 21 is an existing SPD, which includes at least one nonlinear device. At present, nonlinear devices are generally composed of piezoresistors, air gaps, gas anti-electric tubes, multi-layer graphite gaps, transient diodes, solid anti-electric tubes, etc. The general technology of SPD is involved here. The SPD body 21 is in an open circuit state under normal working conditions. When a lightning strike or other surge occurs, the SPD body 21 is in a low resistance state and a large current ...

Abstract

The invention is concerned with the electricity surge protector with proper motion monitoring, includes the SPD body, the signal collector, the processer and the memory cell, there into, the memory cell on the in or outside of the processer can protect the standard configuration of the SPD; the processer, connecting the signal convertor to process the SPD state from the collector to obtain the operating state data, and it can compare the data and the standard configuration with the advanced designed information, at the last, to analyze the result and give remain to the users and / or control the action of the SPD.

Description

technical field [0001] The invention relates to a surge protector, in particular to a surge protector capable of self-monitoring through parameter setting. 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 overvoltage, so SPD is widely used in many fields, such as the field of meteorological disasters. When a surge occurs, SPD will limit the transient overvoltage coming from the line below the withstand voltage value of the equipment through its own characteristics of limiting the transient overvoltage and shunting the surge current, so as to obtain the purpose of protecting the equipment . However, when the surge voltage exceeds the maximum withstand capacity and discharge current capacity of the SPD design, the SPD may fai...
