Problems solved by technology

[0010] On June 20, 1992, the building of the Meteorological Center of the China Meteorological Administration was struck by lightning. The buildings with lightning protection devices were in good condition, but the network of mainframe computers and minicomputers was interrupted, which resulted in a blank CCTV weather report the next day.

Embodiment 1

[0023] Embodiment 1: as shown in Figure 1, adopt polyvinyl chloride as the material of top protective cover layer 1 to petrochemical warehouse and automobile gas station, thickness 1 centimeter. Its volume resistivity is greater than 10 11 -10 13 Ωm, the dielectric strength is 25-50KV / mm. Insulating frame 2 can adopt general nylon, and among the figure 3 is lightning protection warehouse.

Embodiment 2

[0024] Embodiment 2, as shown in Figure 2, for underground and earth-covered gunpowder and explosive warehouses, epoxy phenolic laminated glass is used as the material of the top protective cover layer 1, with a thickness of 1 cm. Its volume resistivity is greater than 1.0×10 13 ΩCm, the dielectric strength is greater than 18KV / mm. The insulating frame 2 can adopt general nylon material. Figure 3 is the lightning protection warehouse.

Embodiment 3

[0025] Embodiment 3, as shown in FIG. 3 , polyamide is used as the material of the top shield layer 1 for the microwave station and the telecommunication room, with a thickness of 1 cm. Its volume resistivity is greater than 10 12 ΩM, the insulation strength is 15-24KV / MM, the same material as the top protective cover layer 1 can be used for the cable wrapping layer 2, and 3 in the figure is a microwave station or a telecommunication room.

[0026] The structure of the insulating frame in the above embodiments 1 and 2 is shown in FIG. 4 .

Abstract

The novel lightning arresting method is to cover the body to be protected against lightning with protecting hood of high resistivity insulating material to keep lightning out. The protecting hood may be made of epoxy phenolic laminated glass or other insulating material and may be attached to insulating frame or used alone. Cables in communication and Internet equipment may be protected with the same material. The method and device of the present invention is superior to available technology, especially for induced lightning.

Description

technical field [0001] The invention belongs to the technical field of lightning protection, in particular to an insulating lightning protection method and device. Background technique [0002] Lightning disaster is one of the ten most serious natural disasters announced by the United Nations International Decade for Disaster Reduction. [0003] China is a domineering country. Thunder can be heard in January and February every year, and lightning strikes may still occur in November. Lightning disasters have caused huge losses to the national economy. According to the incomplete statistics of Guangdong Province, during the four years from 1996 to 1999, there were 6,143 lightning accidents, 699 casualties, 70 fires, and an economic loss of 1.5 billion yuan. How to protect against lightning? So far, the lightning protection technology of the traditional lightning protection theory at home and abroad can be summarized as a word "leading lightning into the ground". Tradition...
