Lightning protection of electric installation and detection device of lightning strikes

Abstract

The lightning protection device includes two capacitors, which is connected to electric utilities or output sides of master power switches of electric utilizes, and the earth connection body. The detection device is lightning strikes includes the gauging meter, which is connected to the outupt side of the said electric utility or the master power switch of the electric utility, the display unit connected to the gauging meter as well as the circuit unit connected between the said gauging meter and the display unit.

Description

(1) Technical field [0001] The invention relates to a lightning protection device, in particular to a lightning protection device for electrical facilities capable of reducing lightning disasters. (2) Background technology [0002] In recent years, affected by changes in the earth's atmosphere, the frequency of lightning that produces high energy has increased significantly. Relatively, it also threatens the residents and buildings on the earth. When the high current generated by lightning enters electrical facilities, it will threaten The life safety of the staff, especially those who touched the electrical facilities at that time will be seriously affected. In addition, it will also damage electrical equipment such as electronics and computers with good electrical conductivity and magnetic conductivity. In severe cases, the power supply transformer will also explode. , Contribute to the spread of the disaster scene fire. [0003] Therefore, the substations of general powe...

Problems solved by technology

[0005] In conjunction with Fig. 2, as shown in Fig. 2, when any point from the outside line of the electrical facility is subjected to the impact of the high-voltage pulse wave generated by lightning, it will not pass through the capacitor 22, so that the output side of the main power switch 21 forms a Surprisingly high-voltage pulse conditions will surely break through the electrical equipment in the electrical facilities, causing greater losses and disasters, and the amount of energy derived from lightning phenomena cannot be estimated. Therefore, when the intensity of a high-voltage pulse wave is much greater than that of the electrical facilities At the maximum value that can be tolerated, a very large amount of current flows instantaneously (about a few microseconds), which not only destroys the facility, but also causes part of the current to flow into the electrical equipment in the electrical facility, causing fire, damage to the equipment, and even damage. Severe disaster with loss of life
