According to reports, the International Wireless Charging Exhibition will be held at Guangzhou Pazhou Exhibition Hall from November 26th to 28th, 2014. The exhibition will showcase wireless charging materials, wireless charging products, wireless charging series equipment, etc., including wireless charging mobile phones, wireless. Charging camera, wireless charging PC/wireless charging tablet, wireless charging TV, wireless charging car, etc.
In 1891, the Russian-born Serbian electrical engineer and physicist Nikola Tesla successfully delivered electricity to the target appliance through electromagnetic induction. Later, for some reason, the research on power wireless was suspended. In May 2001, French scientist Pygnullette made an open experiment at the International Wireless Power Transmission Technology Conference: using microwave technology to transmit electrical energy wirelessly, lighting a 200-watt bulb 40 meters away. At present, wireless charging technology is mainly applied to mobile phones and tablets, but many people are also developing wireless charging technology for automobiles.
Electric vehicles need to rely on charging stations or charging stations. The charging station has a large area and high investment, and it is difficult to promote it in the central area of ​​the city, and the utilization rate is not high. Most of the 12 charging stations built in Beijing are idle. There are also many difficulties in the construction of charging piles. The approval is more troublesome, and the construction cost of charging piles is high, which is difficult to promote in a large area.
Charging piles are like wired routers. One line can only guarantee one computer to access the Internet, while wireless charging is like WiFi, and multiple computers and mobile phones can access the Internet at the same time. With wireless charging, a charging base station in a parking lot can charge multiple electric vehicles within a certain range.
The current wireless charging technology transmission is relatively small, and the distance is relatively short, and can not meet the needs of car charging, but has made gratifying progress in research, such as a meeting in 2012, Chery chief engineer Chen Jun said, Chery is developing high-power car wireless charging technology, "the goal is to reach 3,000 watts, and now can achieve 1500 watts." It is also reported that the wireless charging transmission distance can reach 9 meters, which can already charge at least 10 electric vehicles. The relevant departments should study the feasibility and standardization of this aspect.
In addition, there are people developing mobile wireless power supply technology. According to reports, the United States and South Korea are experimenting with wireless charging roads. Electric vehicles can be driven while charging. It is said that the technical difficulty of this solution is not great, but the cost is relatively high, and it needs to be modified. Existing roads, investment scale is certainly not small. If you consider that a car can carry a small battery to a remote location, this solution can still be considered.
London Mayor Boris Johnson once said that the city carries 75% of the world's population and also produces 80% of the world's pollution. Therefore, cities must take the lead in addressing pollution-related emissions. One important aspect is the use of low-carbon electric vehicles. Therefore, building a wireless trunk road in a big city has great environmental significance.
Wireless charging is a field that has just started. If it can develop effectively, it can solve the charging bottleneck of electric vehicle development to a large extent. However, due to its huge investment in research and development, it needs the encouragement and support of the state to speed up its research and development process and get it as early as possible. Promote the application.
Round Fixing Magnet, or Bushing Fixing Magnet, socket bushing magnet or Insert magnet holder.The round fixing magnet, is a magnetic insert assembly mainly used for holding concrete formworks which made of steel,or holding tools. Its` magnetic force is range from 4 kg ~ 70kgs, which could hold steel structures steadily.
The Round fixing magnet, is made of Neodymium Magnet , steel armature and steel thread rod. The neodymium magnet is plated with NI-CU-NI treatment,the steel armature is treated with Zinc coating, the thread rod is coated with black epoxy. These surface treatment could offer good anti corrosion protections for the bushing fixing magnets.
The inserted fixing magnet consists of cup magnet /base magnet and a separable thread rod. To make sure the adequate pull force,The strongest permanent magnet-NdFeB magnets are used in the embeded socket fixing magnet. The NdFeb magnet are plated with NiCuNiand the metal cup could be plated with color Zinc or other treatments to well protect the metal cup from corrosion. The magnet contact surface should be clean and flat otherwise the actual magnetic force will be reduced. The max working temperature of the embeded fixing
magnets is 80 degrees. Please keep the embeded fixing magnets away fire or being heating. If higher working temperature is needed, the
higher grade NdFeB magnets will be necessary then.The magnetic force and sizes could be designed according to customers' requirements.
Magnetic Bushing Assembly, bushing magnets, bush magnets or magnet bush assembly,are used for retaining tools, lights,signs, and other heavy objects.
Bushing magnet, which configure by a thread hole cup magnet and a separable thread rod to fit the thread hole.Magnetic bushing magnet is made of a strong neodymium magnet,a steel cup and a thread rod. The magnet have been plated with thick coatings to prevent corrosion,please be noted that magnetic bushing assembly is not water proof,bushing magnet could not left in humid environment for months or years.Bushing magnet assembly have very strong magnetic force which could retaining heavy objects.We could produce various sizes of magnet bush assembly. Please kindly inform the model number and quantity when send us inquiry,we could quote soon after calculate the costs.
inserted fixing magnet, a strong Magnetic Assembly for precast concrete industry, it is used to hold neodymium magnet
Inserted fixing magnet,also known as embeded fixing magnet, inserted socket fixing magnet, embeded socket fixing magnet, magnetic pipe ixing magnet,precast concrete fixing magnet.is the new magnetic assembly in precast concrete industry. It is the best solution to fix the
inserted socket in precast concrete panel.
