CT power (induction) power supply, that is, the use of installed powerThe CT on the line is a device that obtains power through the principle of electromagnetic induction, which is composed of two parts: the CT (energy transformer) and the power conversion module (converting the electrical energy obtained by the CT into the required DC voltage). In the field of HV, UHV and UHV transmission, the wires may flow through a huge short-time fault current, and the current sensing power supply needs to be equipped with a special current limiter.
Therefore, taking power from the power line itself is a main idea to solve the problem of online monitoring power supply equipment.
High-voltage induction is the use of high-voltage transmission lines around the induction of electromagnetic energy into electrical energy,Dew, the express cabinet company will give priority to the average daily express volume of 200-300 units of the community, according to the calculation, if a community daily express volume of more than 150, there is a need to install express cabinets.
After more than 10 years of development, SF Express is now the "Big MAC" of China's express industry, with nationwide outlets and distribution network, whether it is the logistics system or supply chain, it is not as good as Meituan. Take aim at the neglected delivery space of "group meals". Some netizens pointed out that the current delivery platform is still relatively safe, because the takeout is smallThe phone I saw was not the customer's real phone at all, and the platform protected the customer's real phone to a certain extent, so friends who ordered takeout generally did not have to worry too much about their phone being leaked.
The first point, traffic advantage. The majority shareholder of Meituan is Tencent, and Tencent's user base is very large. Later, Meituan merged with Dianping, so that it basically has a place in the catering market. Ele. me is backed by Alibaba, Alibaba only word of mouth, Taobao, Tmall, these e-commerce platforms. E-commerce and eating are completely two scenes, so in the flow of the United States group basic victory. Second, moneyInvest.
The strong capital of the United States group into the game, hungry? Market share was squeezed in the same year, the wealth of the big rough United States group to take full strength to enter the take-out industry, because the United States group takeaway provides more complete services and functions, hungry? Suffered heavy losses, market share continues to decline. Faced with the "crushing" of capital, Zhang Xuhao's team fought hard to participate in various entrepreneurial competitions to obtain more financing.
In contrast, or the United States group treatment is better, the United States Group is more single, so the income of take-out staff is also higher than hungry me. But delivery is a very hard work, wind and rain. Although you can not see their high salary, but you do not know their hard work.
Convenience Smart cabinet wireless charging : non-contact smart cabinet wireless charging , compared with the general charger, reduce the trouble of plugging, but also avoid the interface is not applicable, poor contact and other phenomenon, the elderly can also be very convenient to use. (2) Versatility: one charger can be used for multipleLoad charging, a family to buy a charger can meet the whole family use.
Main features From the theory, wireless charging technology, safe and harmless to the human body, the resonance principle of wireless charging is magnetic field resonance, only in the same frequency resonance between the coil transmission, and its smart cabinet wireless charging his device can not accept the band, in addition, The magnetic field used by wireless charging technology is itself harmless to the human body.
Wireless charging is characterized by no charging line restrictions, affected by nickel-metal hydride batteries, this battery has memory, the mostThe best way to use is to reach the best state of the battery after charging. The wireless charging method does not have the bondage of the line, and takes it with each charge, reducing the complexity of plugging and unplugging the data cable. This is more conducive to maintaining the best performance of the lithium battery, without waiting until it is used up and then charging it, and without charging it too full.
W Fast charge and Kirin 980 both take into account battery life and performance. The main features of wireless charging: In theory, wireless charging technology is safe and harmless to the human body. The resonance principle used by wireless charging is magnetic field resonance, which is transmitted only between coils resonating at the same frequencyHis device cannot accept the waveband, and the magnetic field used by wireless charging technology is itself harmless to the human body.
vivox100s wireless charging features: convenience: wireless charging saves the trouble of carrying the charging cable and plugging the data cable, making the charging process more simple. Compatibility: The phone supports a variety of wireless charging devices, and users can choose the right charger according to their needs. High efficiency: Wireless charging technology uses advanced electromagnetic induction principle to achieve efficient charging speed.
Abstract: Wireless charging is a new technology, compared with traditional useData line charging method, wireless charging can not be transmitted through the cable to charge the mobile phone, with safe and harmless, low power loss rate, convenient and other characteristics.
