1K power tariff
bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
the popular digital currencies in 2013 include bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency. At present, hundreds of digital currencies are issued all over the world
the price of bitcoin mining machine ranges from two or three hundred yuan to 200000 yuan. From 2011 to 2013, high configuration bitcoin & quot; Mining machine & quot; From 10000 yuan to 300000 yuan, but the performance is much better than before. According to instry insiders, the old machine can only dig 1 bitcoin in 100 days, but now (2013) machine can dig 3.5 bitcoins in 100 days
according to the miner information published by the domestic assembly team, a miner with the lowest configuration at the price of 3000 yuan can be returned in more than 30 days according to the bitcoin mining speed. The machine with mining speed of 10G / s can dig about 0.03 bitcoins 24 hours a day, while the machine with mining speed of 13g / s can dig about 0.035 bitcoins 24 hours a day according to the computing power and difficulty of the whole network in 2013.
Taking t2t-30t as an example, the calculation force of t2t-30t is 30t, and the power consumption is 2200W, that is, 2.2kW. The power consumption of a single miner in 24-hour operation is 2.2kW * 24 = 52.8kwh, and the electricity charge is once calculated as 0.56rmb, the daily power consumption cost of a single miner is 52.8kw * 0.56 = 29.57rmb
to "mine" with bitcoin mining machine, if the graphics card is fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. There are many professional mines at home and abroad in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even some people in a residential area in Yunnan carried out crazy mining, which led to a large area trip of the residential area, and the transformer was burned
extended data
mining principle of bitcoin mining machine:
bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through point-to-point network, digital signature and interactive proof system. Each network node carries out broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain
every node of bitcoin will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the sha256 hash value of the previous data block. The mining node keeps trying again and again until the random adjustment number it finds makes the hash value lower than a specific target
therefore, computing power trading platforms like 58hash emerge as the times require. Users only need to purchase computing power, trust computing power to the computing power trading platform, pay a certain maintenance fee, and the computing power hosting platform will uniformly maintain the mining machines, and issue the extracted bitcoin to users on time.
transformer type: such as S7, S9, S11...
transformer capacity: such as 100kVA, 125kva, 315KVA...
transformer loss quick calculation table
power factor adjustment table
total active power of the current month
total reactive power of the current month
with the above conditions, it can be calculated manually, Now it's basically computer generated by the power supply company
the specific calculation method is as follows:
1. Divide the total reactive power of this month by the total active power, and calculate the power ratio
2. According to the power rate, check the transformer loss quick calculation table. Here, find out the value of copper loss and iron loss according to the transformer model, capacity and electricity of this month
3. Use the active power and reactive power of this month, plus copper loss and iron loss respectively
4. Divide the total reactive power by the total active power to calculate the actual power rate
5. According to the actual power rate, check the power factor adjustment table to calculate the percentage value of the power adjustment fee
6. Multiply the "percentage value" found by the catalog tariff, the positive number is the tariff to be increased, and the negative number is the tariff to be decreased
hope to help you.
