According to the current trend and the future development direction of technology, I think the next venture outlet may be:

1. Artificial intelligence: With the continuous development of big data and cloud computing technology, artificial intelligence will gradually become the mainstream technology, and more startups will focus on the research and application of artificial intelligence in the future.

Personally, I think that the future entrepreneurial outlet will be the specific application of artificial intelligence. Artificial intelligence has made remarkable achievements and has been widely used in various fields, such as health care, finance, retail, manufacturing and so on. In the future, with the continuous improvement of technology, artificial intelligence will further penetrate into our daily life and various industries, such as smart homes and smart cities. Therefore, enterprises that will devote themselves to the development and application of artificial intelligence will become the next venture outlet. The application of AI technology will also bring more opportunities and challenges.

2. Virtual Reality: Virtual Reality Technology As a developer of artificial intelligence, I think the next venture outlet will be the specific application of artificial intelligence. Although artificial intelligence technology has been very hot in the past few years, its application field still has a lot of room for expansion. Especially in the era when the Internet of Things and cloud computing are booming, artificial intelligence is widely used in various fields such as operation and management systems, and its application scenarios are becoming more specific and diversified.

For example, in the field of intelligent manufacturing and industrial control, artificial intelligence can help enterprises optimize production processes, improve production efficiency and quality, and reduce costs. In the financial field, artificial intelligence can be applied to risk control, fraud detection, investment decision-making and other aspects, and can achieve high-precision and efficient data analysis. In addition, artificial intelligence also has a wide application prospect in medical care, education, transportation and other fields.

There is no doubt that artificial intelligence is the future development trend and new venture outlet. With the advancement and maturity of technology, more and more artificial intelligence startups will emerge in the future. Technology is developing rapidly, and more startups will pay attention to the development and application of virtual reality technology in the future, such as games, education, medical care and other fields.

Application of blockchain technology In today’s digital age, the application of blockchain technology is more and more extensive, which can be used in finance, logistics, medical care and other fields. It has the characteristics of decentralization, high security and high credibility. More enterprises will use and explore it in the future, so the application of blockchain technology is one of the next entrepreneurial outlets.

3. Blockchain: Blockchain is a decentralized technology, which can be applied to various fields, such as finance and supply chain management. In the future, more startups will pay attention to the application of blockchain.

From a technical point of view, artificial intelligence, virtual reality and blockchain all have great potential and market space, but from the current market situation, blockchain is still in its early stage, its application is not extensive enough, and more technical optimization and exploration of application scenarios are needed; The application scene of virtual reality is relatively narrow and the audience is relatively limited; Artificial intelligence has been widely used, but it still needs further development and improvement.

Therefore, I personally think that the next venture outlet may be the development and application of Internet of Things technology. With the rapid development of Internet of Things technology, more and more devices and facilities will have the ability of data collection and transmission, which will give birth to a large number of data analysis and application requirements. At the same time, the Internet of Things will also give birth to a large number of emerging formats, such as smart home, smart city, smart medical care, etc., all of which have great market and commercial value. Therefore, the next few years will be the golden age of Internet of Things entrepreneurship, and various innovative applications based on Internet of Things technology will appear like mushrooms after rain, becoming the next entrepreneurial outlet.

In short, the future entrepreneurial enthusiasm is not limited to the above three areas. With the continuous progress of technology, we can foresee more new entrepreneurial opportunities.

Work temperature is 30 ° C, and the amount of carrier flow under the long-term continuous 90% load is as follows:

1.5 square millimeters – 13A

2.5 square millimeters – 26A
4 square millimeters – 32A

6 square millimeters – 47A
16 square millimeters – 92A

25 square millimeters – 1220A

35 square millimeters – 150A

Current conversion power:

1A=220W,

10A=2200W,

So on and so forth.

For example, if the carrier traffic is 14A, it is: 220W × 14=3080W, then 1.5 square copper wire power is 3.08 kW.

Long-term current allowed by national standard:

4 square is 25-32A

6 square is 32-40A

In fact, these are the theoretical security values, and the limit value is more than these.

The maximum power allowed by the 2,5 square copper wires is: 5500W.

4 square 8000W, 6 square 9000W is no problem.

40A’s digital meter is normal 9000W absolutely no problem. The 12000W of the machine will not be burned.

03

Copper wire wires allow long-term current:

2.5 square millimeters (16A ~ 25A)
4 square millimeters (25A ~ 32A)
6 square millimeters (32A ~ 40A)

for example :

1. Each computer consumes approximately 200 ~ 300W (about 1 to 1.5a), then 10 computers need a 2.5-square millimeter copper wire power supply, otherwise a fire may occur.

2, the large 3 air conditioner consumption is approximately 3000W (about 14a), then one air conditioner requires a separate 2.5 square millimeter copper wire power supply.
3, the current housing outlet is generally 4 square millimeters of copper wire, so the home appliances open at the same time must not exceed 25A (ie 5500 watts), some people replace the wires in the house to 6 square millimeters copper wires are useless. Because the wires entering the meter are 4 square millimeters.
4. Early housing (15 years ago) The import line is generally 2.5 square millimeter aluminum wire, so the home appliances open at the same time must not exceed 13A (ie 2800 watts).

5, household appliances that are relatively large consumption are: air conditioner 5a (1.2), electric water heater 10a, microwave oven 4a, rice cooker 4a, dishwasher 8a, drying machine 10a with drying function, electric heater 4a.

Among the fire caused by the power supply, it is due to the heat of the hair, so all the joints must be welded, and the contact devices that cannot be welded 5 to 10 years must be replaced (such as socket, air switch, etc.).

Copper wire wire cable traffic standard cable flow oral estimation:

Take the next two o’clock in nine, and go to the next time.

Thirty-five take three o’clock, double bunom group is five.

The conditions have changed, and the high temperature is 10% off copper upgrade.

The number of tube is two or three four and eight seven six folds.

illustrate:

This mouth is not directly pointed out to various insulated lines (rubber and plastic insulation lines), but "cross-section is multiplied in a certain number" to be represented.

"Two five-point multiply by nine, go to the next time," said that various cross-sectional aluminum insulation lines of 2.5mm2 and below are about 9 times the number of carriers of the cross-section. Such as 2.5mm2 wires, the carrier flow is 2.5 × 9=22.5 (a). The multiple relationship between the carriage of 4mm2 and more wires and the number of cross-section is row, the line number is row, the multiple is successively reduced by 1, i.e., 4 × 8, 6 × 7, 10 × 6, 16 × 5, 25 × 4.

"Thirty-five Take Three Fiveth, Double Bunction] Say", it is said that 35mm2 lead traffic is 3.5 times the number of cross-section, ie 35 × 3.5=122.5 (a). Wire from 50 mm 2 and above, the multiple relationship between the amount of carrier flow and the number of cross-section becomes a set of two two lines, and the multiple is 0.5. That is, 50, 70mm2 wire has a total of 3 times the number of cross-section; 95, 120 mm2 lead traffic is 2.5 times the number of cross-sectional area, and push it according to the secondary.

"Conditions have changed, high temperature nine fold copper upgrades". The above mouth is the copper core insulation line, which is determined under the condition of 25 ° C in ambient temperature. If the aluminum core insulation line is in the area where the ambient temperature is higher than 25 ° C, the wire carrier flow can be calculated according to the above-mentioned oral calculation method, and then hits it again; when used is not an aluminum wire but the copper core insulation line, Its carrier flow is slightly larger than the same size aluminum wire, and can calculate a carrier flow than the aluminum wire in the above-mentioned oral method. For example, the flow of 25mm2 copper wire can be calculated according to 25 mm2 aluminum wire.
