With the new building materials and the application of new technology, the development of the modern architecture with each passing day, top, ultra-high buildings appear constantly, lightning protection is becoming more and more important disaster mitigation. But there are still a part of building developers the harmfulness of lightning, damage degree is not enough, and know for granted. In the province lightning protection engineering quality surveillance offices in the first half of this year the lightning protection device found in xining city special acceptance, more than 90% of the buildings installed the lightning protection device, but a lot of lightning protection device became decoration.
Xining of thunderstorm high area
Lightning protection in qinghai province project quality surveillance offices MaHaiLing webmaster office, stick on the wall of a lightning distribution of qinghai province particularly noticeable. According to information, in our province, the number of annual thunderstorms all regions for 40 days to 80 days, its area and strong thunderstorms thunderstorm area. Among them, the number of xining annual thunderstorms for 40.3 days, have more than many thunderstorms area with an average annual number of thunderstorms 40 days, high standard of thunderstorm area.
Due to global warming, the influence of factors of xining city of LeiRi and end early thunderstorm LeiRi in the emergence of of former April and September to now and November 3 month. At the same time, along with the speeding up of the province city construction and electronic equipment, the rapid popularization of lightning the loss has also more and more big.
《Xining defense lightning regulations》Provisions, and new construction, expansion of building, the construction units shall be the lightning protection engineering construction plans to send to the competent meteorological departments of city, county by the competent meteorological department audit, through audit, it should the competent meteorological department under the supervision of audit, according to after lightning protection engineering design construction. Lightning protection project is completed, the competent meteorological department at the acceptance notice, without acceptance or acceptance not qualified, shall not be delivered.
According to MaHaiLing introduced in the first half of this year, lightning protection device found in xining city special acceptance, more than 90% of the buildings installed the lightning protection device, but the results are not what acceptance. Many lightning protection device became decoration, acceptance rate is only 60%. And who; Many people think that little rain lightning disasters in qinghai, not serious, but that is not the case, especially June to August, the more to strengthen the guard, alert the accident. Lightning Xining 40% of buildings and lightning protection device is unqualified, lightning protection status is not optimistic. And throughout; MaHaiLing said.
Be careful, lightning protection equipment, lead thunder home invasion
Buildings to avoid the protection zone are in the roof, the elder exposed by nature, aging, man-made destruction and other factors to avoid, with different degree will be damaged, the damaged lightning protection equipment not only do not rise to lightning protection function, but the danger of existing lead thunder home invasion. If not on time for lightning protection safety check, can discover in time and eliminate hidden dangers and lightning protection device can't play their due the action of safe protection. Therefore, buildings and lightning protection device of the acceptance, still should each year for lightning protection safety testing in flammable and explosive place, the lightning protection device must be inspected once every six months.
My home village, there seems to be a lightning protection equipment, home outfit solar energy water heater, good DuoRen all say the roof have lightning rod. Live in the provincial capital of the street bridge song lady told reporters, although know the seriousness of the accident, but lightning because never happened in its own and the surrounding relatives and friends body, also didn't seriously.
A lightning rod can lightning protection? MaHaiLing explanation: want to rise to lightning protection function, not a lightning rod can, because lightning protection device is shows, led by referral, grounding device and so on lightning protection products and the floorboard of the facilities, if one link wrong, lightning protection effect will sell at a discount greatly.
According to MaHaiLing introduction, check that many people on the platform of the installation on the roof of the solar energy water heater equipment. Because some people don't know to avoid, the top have with the solar energy water heater equipment to avoid a higher than with, and no and avoid around with connected. Once appear thunderstorm, would be likely to not promptly lightning current leaks out, cause the consequences of lead thunder home invasion. Therefore, she reminds building management personnel and citizens in the roof at will, don't install electrical appliances, disorderly pull wires, lightning protection device on time, can be in yearly check to a great extent by lightning avoid accident.
Weather, don't use 10 million lightning solar water heater
With electrification of the equipment to increase gradually, the induction lightning current is also more and more sensitive. In the odor which always comes before a thunderstorm, people should shut the doors and Windows, cut off home all kinds of home appliances of power supply, do not come near to the doors and Windows, pipes, the outdoor heating tube, gas pipe and metal pipe, should learn hedge common sense, improve the lightning protection lightning protection hedge self-rescue ability, as far as possible will be struck by lightning accident loss to the minimum.
At the same time, when a thunderstorm don't use solar energy water heater, avoid water heater on the roof and roof meet current induction lightning to indoor injuries. But if in outdoor weather and have encountered thunderstorm couldn't find the right place to avoid should be used when focus and reduce human body to reduce as much as possible with the ground of the way to avoid the contact area by lightning damage. With both feet touching down on his knees, hand, body forward bend, if can put on your raincoat, lightning protection effect will be better.
