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

[0028] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0029] The invention relates to an online detection device of a surge protector, which comprises an electric power detection unit (1), a signal conversion and transmission unit (2), a data analysis unit (3), a circuit (8), a transmission path (9), and an electric power detection unit (1). The power detection unit (1) includes a pressure sensor (10), a push rod (5), and a metal component (6). The metal member (5) is insulated from the pressure sensor (10).

[0030] It is then transmitted to the data analysis unit (3) through the transmission path (9) for analysis and comparison, so as to know the physical quantities such as the magnitude and number of surges flowing through the surge suppression device (4), the degree of degradation of the surge suppression device, and realize The detection function of the surge protector (7).

Abstract

The invention relates to an online detection device of a surge protector, which comprises an electrodynamic force detection unit (1), a signal conversion and transmission unit (2), a data analysis unit (3), a circuit (8) and a transmission pathway (9), wherein the electrodynamic force detection unit (1) comprises a pressure sensor (10), a mandrel (5) and a metal component (6). The sizes and frequency of surges flowing by a surge suppressor (4) are obtained by measuring and analyzing electrodynamic forces to obtain the physical quantities of degradation degree and the like of the surge suppressor to realize the detection of the surge protector (7). The online detection device has the characteristics of convenient mounting, high detection accuracy, quick response and capability of effectively reducing fault points.

Description

technical field [0001] The invention relates to an online detection device of a surge protector, 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, ...
