Problems solved by technology

In this technical field, an important problem currently exists is that while the surge protector is protecting the equipment, its own components will gradually deteriorate until they are completely damaged, or they will be directly damaged under excessive surge impact, or cause Switching surge protection devices generate freewheeling; for power surge protectors, damage or damage can be caused by short circuit (including freewheeling, omitted below) and heating caused by increased leakage current; for signal surge protectors, The damage phenomenon is generally the increase of the impedance of the surge protector to signal transmission and the short circuit of the surge protector.
The problems in this method are: 1. The deterioration or damage of the surge suppression device may not generate enough energy to make the tripping device move, and the alarm unit cannot perform alarm output at this time.
2. The alarm signal may be output only when the device is damaged, which cannot be predicted in advance
Its defect is that the temperature switch cannot accurately and timely reflect the temperature change of the surge suppression device, so the temperature information that can be used for judgment is not sufficient and direct

Embodiment Construction

[0024] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0025] A surge protector with a detection device includes an electric power detection unit 1 , a signal conversion and transmission unit 2 , a surge suppression device 4 , a line 8 , a connection terminal 9 , and a casing 10 . The electric power detection unit 1 includes a pressure sensor 3 , a push rod 5 , and a metal member 6 .

[0026] Way of working:

[0027] 1. When the lightning surge passes through the surge suppression device 4 and the metal component 6, the current will cause the bent metal component 6 to have a straightening effect and generate electromotive force;

[0028] 2. The generated electric power is transmitted to the pressure sensor 3 through the ejector rod 5;

[0029] 3. When the pressure sensor 3 is under pressure, it outputs an electrical signal, which is transmitted to the signal conversion unit 2 through the line 8;

[0030] 4. The sig...

Abstract

The invention relates to a surge protector with a detection device. The surge protector (7) with the detection device comprises an electric power detection unit (1), a signal conversion transmission unit (2), a surge suppressor (4), a circuit (8), a connecting terminal (9) and a shell (10), wherein the electric power detection unit (1) comprises a pressure sensor (3), a post rod (5) and a metal component (6). The electric power is measured to acquire the magnitude and the number of times of surges which flow through the surge suppressor (4), and also acquire whether the surge protector is damaged and the degree of deterioration, thereby realizing the surge protector (7) with the detection device. The invention has the advantages of convenient installation, high detection precision and sensitive response, and can effectively reduce the fault points.

Description

technical field [0001] The invention relates to a surge protector with a detection device, which belongs to the field of lightning protection equipment. Background technique [0002] Lightning and the line surge caused by it and the line surge caused by other reasons are important reasons for the aging and damage of electrical and electronic equipment. Installing surge protectors on metal lines such as power lines, signal lines, and control lines connected to electronic equipment is one of the important measures for lightning protection. In this technical field, an important problem currently exists is that while the surge protector is protecting the equipment, its own components will gradually deteriorate until they are completely damaged, or they will be directly damaged under excessive surge impact, or cause Switching surge protection devices generate freewheeling; for power surge protectors, damage or damage can be caused by short circuit (including freewheeling, omitte...
