How can a anxiety lightning protection

[REVIEW] Recently, the municipal meteorological bureau director Yang Hongming lightning led scientists to the countryside publicity lightning weather knowledge, we found that some residents in rural areas housing the city\\ s roof installed , water heaters due to the lack of these mine facilities, a move Ray\\ s problems.

      At present, solar water heaters strokes occurred in 4 cases mine incident

Recently, the Municipal Bureau of Meteorology weather mine director Yang Hongming led scientists to the countryside publicity lightning knowledge, we found that some residents in rural areas housing the city\\ s roof installed solar water heaters, water heaters due to the lack of these mine facilities, a move the hidden mine .

\"The city estimates more than 5,000 solar water heaters, and some are also installed in the school dormitory roof. Water heater installed in the roof, with a security risk, appealed to residents to promote mine awareness, mine water heater initiative to do the work without the required placement of anti- mine facilities, in accordance with relevant provisions of the law enforcement agencies can weather more than 500 yuan imposed a fine of 30,000 yuan. \"

5,000 solar water heaters move the status quo Ray

Recently, Yang Hongming housing area to a small village Lotus Township inspection mine work, we found the village several solar water heaters.

Summer is high season for thunderstorms, but the city is more than mine. This is mainly due to erosion of the hilly landscape is Suining, hilly, Gully aspect, to spread all over the canal, the middle of the low-lying four-week high, coupled with the outer edge of the subtropical high in summer climate, abundant water vapor, so prone to lightning phenomenon. The solar water heaters are generally placed in the roof, if the anxiety of mine facilities, are more vulnerable to lightning.

\"Solar water heaters, metal structures are more common with electric heating, and roof installation location is generally higher than the height of lightning rod and lightning protection zone, in the absence of effective lightning protection measures, it is easy to become a lightning target. Ranging from water heater explosion destroyed, while in direct electrical injury were the survey shows that since April this year, within the city there were 963 times the number of lightning, thunder and lightning intensity of 57.6KA. \"Yang said. \"According to preliminary estimates, the city\\ s rural areas are currently about 5,000 various types of roof water heaters, water heaters being struck by lightning cases have occurred as of now, the city, there were four events from the water heater lead mine.\"

Dealers that sell water heaters do not need lightning protection

Not long ago, as a consumer reporter came to City a solar water heater sales store and see the huge store on display at forty-five kinds of brands of solar water heaters. Boss said: \"Last year we sold more than 500, are not safe lightning protection, we use the water heater you though, no problem, because there is no sharp part of the water heater.\" Vendor of mine work on solar water heaters so indifferent, Reporters are very worried.

Product safety requirements by country, solar water heaters to be installed lightning protection facilities, and its products also have the instructions to install lightning protection facilities, notes, general dealer has failed to install, is the disregard for life and property safety of consumers.

According to reports, if mine own solar water heater deal, first distance away from the installation of water heater 3 m 1.5 m above the water heater at the top of the lightning rod, and do protect against lightning; Secondly, from the roof the introduction of solar water heater indoor power lines, signal lines, water pipes should be metal shielding; Finally, you should install leakage protection switch back-end SPD (surge protector), and do protect against lightning and the lightning induced wave intrusion.

According to statistics, Suining average number of lightning strikes up to 30 days to record up to 60 days, is more than mine. Farmers mine awareness weak, so the solar water heater installed lightning protection for these facilities is a priority. It is understood that the wall below the floor construction of solar water heater, do not worry about summer lightning problems.

Focus is to prevent an extension of flammable and explosive places

At 14:40 on August 30, 2007 about the British soaked village of Carp River County Chi Yang Hui 10 group home struck by lightning, 12-year-old student died on the spot. According to the survey, the day of the accident, lightning is the summer period, Yang Hui was at home watching TV, suddenly found TV outlet in the sparkle, immediately went to pull the plug, and instantly a strong line of lightning current through the light spot to Yang Hui fatal. According to the survey, Yang Hui\\ s family was then struck by lightning off in the area, building on top of the CCTV line lightning protection measures are not taken; Second, the overhead wires from the house side of the house too close (less than 3 meters), hundreds of thousands of volts of lightning voltage the formation of lightning counter-attack; Furthermore, the whole house is not installed lightning protection devices, power line installation is extremely irregular.

At 3:35 on August 16, 2009, Berlin Township, the village housing area Lotus group 3 a lightning accident occurred, the lightning causing Wang Chenghai residential building and the surrounding villagers were Jihuai appliances, resulting in total direct economic losses of 3.8 million. The same reason lightning lightning lightning protection devices are not installed, the roof water heater is not connected to potential measures, overhead power supply, signal line lightning protection measures are not taken.

\"Mine detection involves various sectors and systems, with emphasis on flammable and explosive places, schools, hospitals, financial institutions, construction projects and enterprises, institutions, but some units did not take the initiative to submit applications for mine safety inspection, or only a partial test. Overall, the city\\ s annual inspection of lightning protection device surface is still relatively narrow, some units can not attract enough attention, as part of the communications sector and individual enterprises, institutions, and every year its been due to lightning The loss is not small. Furthermore, is part of the construction project will be construction of lightning protection devices are not reviewed construction, after completion of the project did not pass acceptance testing will be completed and put into use in rural areas, urban building rooftop solar water heaters and other electrical devices generally do not take lightning protection measures which are very security risks. \"Yang said.

Occurrence of lightning in the atmosphere of intense discharge phenomenon, usually in a thundercloud (cumulonimbus) has happened. Lightning can be divided according to their location of occurrence of lightning within the cloud, inter-cloud lightning, cloud-air lightning and cloud-ground lightning. Cloud to ground lightning discharge is formed when the intense thermal effects, electrical effects, mechanical effects and electromagnetic effects, can be very destructive, the production of people\\ s lives and safety of a larger threat.

Most vulnerable to lightning strikes in life objects are the building angle, roof, eaves, gables, parapet; building on the exhaust, the exhaust pipe; a subsidiary of metal buildings, such as solar water heaters, etc.; tall tree; Square, playgrounds and other places of the flag; transmission and distribution lines and towers, radio tower, communication base stations, billboards and other large metal objects tall.

Inner conflicts, lack of supervision and more solar water heaters

    In recent days, reporters continued to receive some people call the hotline, complaints burst, or the consumer and business disputes arising on the issue of compensation. So, the sales of solar water heaters in the capital today? Water heater how to use after installation? Reporters launched an investigation.

Solar water heaters cause all kinds of disputes

July 16, who lives in the five towers of the public gardens reflect Ms. Chen, from the second floor of households installed solar water heaters in the roof, the roof of the home frequent leakages. Ms Chan told reporters: \"From last year, my family has been flooded three or four times, that is caused by solar water heater leaking, I often consult with tenants on the second floor, at first the other side also paid me some money, but this did not solve the total question, my family has just completed renovation on the leaking now and made us very nervous neighborhood, on the second floor tenants that the victims themselves, but in consultation with the dealer paid unsuccessful. encountered such a situation exactly who bear the responsibility? \"

Similarly, public Zhang also met a few days because of trouble caused by the solar water heater mind. July 11 afternoon winds, resulting in Mr. Zhang\\ s installed in the roof were blown. Mr. Zhang said: \"loud noise was heard outside the house, my home solar water heater installed in the roof of the wind turned from the top floor was a large fall on the ground, while others are home safe and sound. Water heater storage tank and stand at the same time plunging to the ground, Almost all stand on the broken pipe, storage tank and water tank severely deformed. Fortunately, there was no pedestrian through, causing no casualties, but smashed the downstairs of an electric bicycle, because the payment, I was, and distributors negotiations, but in any case they do not recognize their own installation problems. \"

Metal market is gradually fading out

Reporters visited the old district found that years ago the use of metal tube solar water heaters (solar water heater industry, also known as brass) users are reflected to the correspondent, the water heater installed in an attic within a brass have been stolen, or is replaced, resulting in their own home solar water heater is not working, gradually the water heaters was idle, and with the increased consumer demand, the metal-type solar water heater water heater manufacturers have been eliminated.

Ms. Zhang, who lives in a small Black River nearby, told reporters: \"In 2006 when we installed a total of 28 residential units of metal tube solar water heater, the results within a few days remaining copper was stolen on a few, which are small theft go, but does not rule out someone\\ s after-sales maintenance man when the water heater repairs, pilfering stealing copper pipes for our family. \"

Post reporter went to the original residential building area, see the installation of a metal roof tube solar water heater, under the guidance of the residents, the reporter found that the district leading to the roof of the channel has been locked. Resident of the uncle explained to reporters: \"A few years ago lost brass particularly frequent, then we put residential property company locked the channel leading to the roof, and if someone needs water heater repair, maintenance personnel come until after the first to the property register, and then hand accompanied by the property company, maintenance personnel can reach the roof, much to avoid stolen or stolen for the copper case. \"

Why become a copper thief goals? Why this type of water heater abandoned it? With these questions, the reporter interviewed Tsinghua Solan solar water heater dealer Wang. Mr. Wang told reporters: \"general each metal tube solar water heaters, the installation of a 18 brass, a copper\\ s copper production of material removed can be sold for 10 yuan, after taking about, and sometimes inside the metal tube brass copper stolen will be sold out, so start with the goal to become a thief now in the district where such water heater is almost depleted, the installation location in the corner might be able to survive, but according to my observation This water heater is basically no one will use. \"

\"The current market for solar water heater, replaced almost all the solar water heater vacuum tube, and hand over the metal tube security, on the other heat-absorbing performance, parts are not easily stolen, while the metal tube solar water heaters in winter easy cracking, coupled with relatively high replacement costs, if all the replacement cost is about the thousand or so, causing many families to the original idle water heater, water heaters are gradually eliminated from the solar water heater market. \"Wang added further said.
