Because of his excellent hardware maintenance skills, pinghu city Public Security Bureau recruited talents in this field in 2000, so Yan Bing came to Pinghu. "Electronic and electrical equipment is updated quickly, so I should pay attention to improving my technical level every day in order to solve all kinds of' intractable diseases' in time." As Yan Bing said, the monitoring equipment, hardware and network equipment of the Public Security Bureau are not only quite numerous, but also very complicated. In the first few years, he spent almost half a day reading electronic information newspapers. Through repeated practice and operation, he improved his professional level, ensured that he could troubleshoot in the shortest time every day, and ensured the smooth flow of public security electronic communication and network. His name is Yan Bing, 38 years old, and he works in pinghu city Public Security Bureau.
The striking thing about Yan Bing is that he knocked on a "home power plant"-solar power generation device. He installed 65,438+06 solar panels on the roof. Absorb solar energy and boost the battery. After the inverter is converted into alternating current, the maximum output power can reach 800 watts. In addition to the air conditioner and refrigerator, Yan's family uses the network of the electric power department to supply power, and the others, such as electric fans, computers, stereos, televisions and lighting lamps. They all generate electricity by themselves.
Yan Bing said that if the battery is fully charged, even if it rains for two weeks or half a month in a row, the basic electricity consumption at home can still be met. Because these two "even if" are almost impossible to happen, his family is not short of electricity all the year round. Since having this solar power generation device, Yan's family is no longer worried about the problem of electricity consumption, but about the surplus of electricity-in winter, in order to prolong the service life of the battery, several lamps are turned on for discharge treatment 24 hours a day. Yan Bing's research on solar power generation devices began in the early 1990s. At that time, he lived in Danghu Community on the outskirts of Pinghu. Due to the tight power supply, he often cuts off power and his life is very inconvenient. Yan Bing turned his attention to solar power generation: If we have such a set of equipment at home, wouldn't it save money and worry? But he soon found that it was very expensive to buy ready-made solar power generation equipment in the market, and it would take several years to recover the cost. Yan Bing worked as a soldier, engaged in communication maintenance in the army, had a soft spot for electrical appliances, and suffered from lack of electricity. He began to peck at the homemade power generation equipment.
With the help of friends, Yan Bing has extensively collected parts of solar power generation equipment in Shandong, Gansu, Beijing and Xinjiang. Whether it is a broken monocrystalline silicon plate or a scrapped battery, he buys it back as a treasure, and then repairs and assembles it according to what he usually learns, turning waste into treasure. After half a year, the solar power generation device was successfully developed. Yan Bing installed two groups of four panels at home and enjoyed the "free electric meal" provided by Grandfather Sun. After moving into the new house in June 2003, Yan's house area reached 1.78 square meters, and household appliances were also fully equipped. The original power generation device could not meet the demand, so he began to consider "expanding the scale". In order to achieve the best power generation effect, he browsed a bunch of self-defined electronic magazines to "charge" and often "entangled" with solar street lamps on the roadside. Finally, on the basis of the prototype ten years ago, he assembled an improved power generation device, including eight sets of 16 solar panels and an inverter with an output power of 800 W.
Of course, homemade generators are also risky. If the safety measures are not in place, it will bring "disaster" to the family. Yan Bing is well aware of this and has taken careful security measures. In order to prevent "cross power supply", he installed a two-way knife that can be completely disconnected at the connection of two sets of lines powered by solar energy and power grid; In order to avoid accidents caused by overheating of the circuit, he installed a thermostat in the power distribution room of the attic. When the inverter temperature reaches 75℃, the thermostat will automatically stop working. In addition, he bought three portable fire extinguishers in case of accidents. The evaluation given by electric power experts on-site reconnaissance is: absolutely safe. In recent years, there has been a "power shortage" in East China. Last year, during the peak period of electricity consumption, Yan Bing Xingzhou Sunshine Community had to cut off power twice a week. The residents couldn't stand the heat, so they went outdoors to enjoy the cool, and had to light candles in the dark at night. Yan Bingjia sat on the Diaoyutai, and the 500W light in the indoor living room made his house as bright as day at night, and the electric fan blew tirelessly. His son's classmates heard of such a good thing and went to his house to "cool off" after school.
After the solar power generation device is put into use, the economic benefit is very obvious. The monthly power supply fee of other residents in Sin Chew Sunshine Community 160-70 yuan, and the amount shown in the payment notice he received has been stable at the level around 30 yuan. Moreover, the cost he spends is not high: the market price of a battery panel with the same area reaches 500 yuan, and he only needs 30 to 40 yuan to repair it; The inverter of the same specification on the market sells 1500 yuan, and he only spends less than 300 yuan; The investment of the whole set of equipment is only 3000 yuan. Yan Bing's invention alarmed experts in Jiaxing and Pinghu power departments. They joked that if everyone was like Yan Bing, except for a few large power plants, small power plants would have to be closed. With this invention, the Yan family gradually became lively. In the past, there were many people, because my son and classmates came to "cool off" and neighbors came to see it. There are many people now, but most of them are visiting and studying. Some people who are keen on solar energy development came to consult, and manufacturers from Wujiang, Fuyang, Huzhou and Haining in Jiangsu also came to learn from them. Even a group of "talent scouts" came to the door and promised him a large sum of money to invite him out of the mountain. In this regard, Yan Bing always smiled and shook his head: business exchanges and negotiations are possible, but I can't leave my beloved public security team.
Yan Bing has an idea. Now the whole city is engaged in the construction of street monitoring, but it costs a lot. Pinghu has installed 33 probes this year, and it has spent 330,000 yuan on power distribution and power supply alone, and will have to pay the electricity bill in the future. He is considering how to replace it with solar power generation devices. If this move is successful, it can save hundreds of thousands of yuan for the unit, benefit from one-time investment for life, and don't have to spend electricity bills in the future.
