Instantaneous starting power of mining machine
the power consumption of bitcoin mining machines is different according to different machines take Shenma 68T, the fastest mining machine in wet season, as an example. Suppose that the electricity charge is 0.22 per kilowatt hour in half a year in wet season and 0.34 per kilowatt hour in dry season, the wall power consumption of Shenma 68T's second-hand machine is 3264w, and the actual power consumption is 3500W, then the daily power consumption of a Shenma M20S 68T machine is 3.524 = 84 degrees, Annual power consumption 84 * 365 = 30660 degrees
according to the latest mining difficulty, a Shenma 68T machine can dig 0.00064836 BTC a day, and 10 machines can dig 2.366514 coins a year. The mining difficulty of the premise remains unchanged, but according to the current situation, it is assumed that the mining difficulty will increase by 30% from now to next June, and by 2.5% every month. It is estimated that 85% of the original coins should be g, that is, 2.012 coins. Ten machines of Shenma 68T can dig almost 2 coins a year
to sum up, the power consumption of ten Shenma 68T machines in a year is 306600 kwh, which can dig almost two coins

extended data
the risk of mining machine
1. Hardware expenditure
< P > mining is actually a competition of performance and equipment. Some mining machines are composed of more such graphics card arrays. With tens or even hundreds of graphics cards, the hardware price and other costs are very high, There is considerable expenditure in miningin addition to the display card burning machines, some ASIC (application specific integrated circuit) professional mining machines are also put into the battlefield. ASIC is specially designed for hash operation, and the computing power is quite strong. Moreover, because their power consumption is far lower than that of the display card, they are easier to form scale, and the power cost is also lower. It is difficult for single chip display to compete with these mining machines, This kind of machine costs more
2. Currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but the frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
3. System risk
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners
take an ant s9-13.5t mining machine as an example, the power is 1.35kw
the power consumption of 24 hours a day is: 1.35kw * 24h = 32.4kw/day
according to your local electricity charge, assuming that the electricity charge is 0.5 yuan / kWh, 32.4 * 0.5 = 16.2 yuan / day
then an ant s9-13.5t mining machine can consume 32.4 kwh a day, The daily electricity charge is 16.2 yuan
if you have any other questions, you can consult me and hope to help you, thank you!
you can think of sending the intercepted URL short message, and then provide the specific location to intercept
your three-phase 10kW motor current is generally about 20A, The power factor is not as simple as you think. It's very complicated to calculate. Here I will tell you that it's 20 A. if there is a single-phase load, the current is larger than 45 A. It can be taken as 60 A.
it is recommended to use a 100A three-phase meter, which is 3 * 100
1. First of all, we come to the position of the mining machine, where we need to buy sticky bombs to aim at the secret passage, and after the secret passage is exploded, we can go down the tunnel
2. You can see the miner under the tunnel. Just go to the front of the miner and start the switch. At this time, we need to wait for a period of time. During this period, some NPCs will attack, and the damage is relatively high. We need to use certain weapons to defeat them
there will be about 3000 gold bars in the mining machine. In the gold island, the number of gold bars can be said to be a wave of fertilizer, which is enough to pay the evacuation expenses. 7000 gold bars need to be prepared for evacuation. If you want to use gold bars to get out, don't use too many gold bars
the above is the whole content of how to start the mining machine of peace elite gold island mine. I hope it can help you.

according to P = FV, 6KVA generator, the output current is only 24a, a 7.5kW water pump and 5.5kW mining machine, the total power is 13kw, the normal current has 26a, overload. Moreover, the starting current of the motor is larger, that is, the starting current of 7.5kW is about 30A. If the 7.5kW is started first, the working current is already 15a, and then the 5.5kW is started, the starting current is 20a, and the total current is 35A

it's mainly about the selection of contactors. It's better to use contactors with larger capacity, because the water pump motor starts with load, and the current at the moment of starting is too large, which will cause great damage to the contacts of contactors. If the selection is small, it will affect the service life of contactors
The output voltage of the generator should be increased correspondingly ring the motor starting process to protect the voltage drop ring the motor starting. There should be no problem with 3KW motor with 1.5KW. It is enough to adjust the speed of the generator ring the start-up< br />
