The red light and green light of S17 are not on

1. Did you make a loud noise when you first bought it? If not, maybe it will be better if the machine gets old, parts wear out or impurities fall into the machine

2. Yinbit is recommended. Yinbit is a maintenance brand of coin printing. It is an official quality maintenance brand established by an old maintenance team. It has five years of ant mining machine maintenance experience and has excellent strength. It can realize the quick repair of ant 17 series and apw9 / apw9 + power supply. It is one of the few maintenance brands in the instry that can quickly repair high computing power models. At the same time, it undertakes the business of rescuing S17 and T17 scrapped computing power boards, At present, there are maintenance sites in Cheng, Sichuan, Dehong, Yunnan and Xinjiang
at the same time, Shenma M20 / M21 series and p21 power supply quick repair can also realize quick repair with quality assurance because they are authorized maintenance brands of Shenma and Xindong.

4. Ant S7 traffic lights are not on, should be the problem of low voltage or poor heat dissipation. Suggest to go, you can go to the official to ask, technical personnel will let you know. It's not a problem.

5. The common classification methods are: according to the constituent elements, according to the carbon framework, according to the functional groups< 1. Hydrocarbons: organic compounds containing only hydrocarbon elements, such as alkanes, olefins, alkynes, aromatics, etc
2. Hydrocarbon derivatives: a series of compounds generated by the substitution of hydrogen atoms in hydrocarbon molecules by other atoms or atomic groups are called hydrocarbon derivatives (or compounds containing hydrocarbon and other elements), such as alcohols, aldehydes, carboxylic acids, esters and halogenated hydrocarbons< According to the carbon framework, organic compounds can be divided into two categories:
1. Chain compounds: the carbon atoms in the molecules of these compounds are connected to form chains Because it was first found in fat, it is also called aliphatic compound.)
2. Cyclic compounds: these compounds contain cyclic structures composed of carbon atoms. It can be divided into three categories:
(1) alicyclic compounds: a class of carbocyclic compounds with similar properties to aliphatic compounds
(2) aromatic compounds: compounds containing benzene ring in molecules
(3) heterocyclic compounds: in addition to C, there are heteroatoms in the ring skeleton, which are called heterocyclic compounds< According to the classification of functional groups, functional groups are the atoms or groups that determine the main properties of compounds
1. Alkanes: Alkanes have no functional groups, and are characterized by the formation of chain like carbon carbon single bonds, and the remaining valence bonds are all combined with hydrogen atoms
2. Olefin: the functional group is carbon carbon double bond, - C = C -
3. Alkyne: the functional group is carbon carbon triple bond
4. Benzene and its homologues: the functional group is benzene ring
5. Halogenated hydrocarbon: an organic compound with alkyl group and halogen. The functional group is halogen, - x (x = f, Cl, Br, I)
6. Alcohol: an organic compound with aliphatic alkyl groups and hydroxyl groups. The functional group is hydroxyl, - oh
7. Ether: organic compound with alkyl or hydrogen atom linked to ether bond. The functional group is ether bond, - C-O-C -
8. Phenol: an organic compound whose benzene ring is directly connected with hydroxyl group. The functional group is hydroxyl, - oh
9. Aldehydes: organic compounds with alkyl and aldehyde groups connected. The functional group is aldehyde group, - Cho
10. Ketone: an organic compound with alkyl and carbonyl groups connected. The functional group is carbonyl
11. Carboxylic acid: organic compound with alkyl or hydrogen atom connected to carboxyl group. The functional group is carboxyl, - COOH or HOOC -
12. Esters: organic compounds with alkyl or hydrogen atoms connected to ester groups. The functional group is ester group, - coor or rooc -
13. Amine: an organic compound in which the alkyl group is linked to the amino group. The functional group is amino, - NH2 or H2n -
14. Nitro compounds: organic compounds with alkyl and nitro groups. The functional group is nitro -, NO2 or o2n -
15. Sugars: polyhydroxy aldehydes or polyhydroxy ketones and organic compounds that can hydrolyze to proce polyhydroxy aldehydes or polyhydroxy ketones. The functional groups are hydroxyl and aldehyde or carbonyl, - oh and - Cho or - co -
16. Oil: glycerides of various higher fatty acids, the functional group is ester group, - coor
17. Amino acids: organic compounds formed by the substitution of hydrogen atoms of alkyl groups in carboxylic acid molecules by amino groups. The functional groups are carboxyl and ammonia
groups, - COOH and - NH2
18 α— A polymer compound formed by condensation of amino acids. The functional groups are carboxyl, amino and peptide
bonds, - COOH, - NH2 and - CONH -.

6. The electricity price of urban and rural "one household, one meter" households in Sichuan Province will be reced by 0.15 yuan / kWh from 181 kwh to 280 kwh in wet season, and 0.20 yuan / kWh for the part with monthly electricity consumption higher than 280 kwh. The current low valley electricity price, free electricity consumption base of urban and rural "low income households" and rural "five income households" will remain unchanged< p> If the electricity charge is specific, you can see the electricity charge notice in the picture:

7. According to the electricity price you said, it should belong to the electricity price of "commercial and non residential lighting". The implementation is peak valley electricity price: 7:00-11:00 am, 19:00-23:00 PM is the peak time electricity price; From 11:00 to 19:00 in the daytime is the normal electricity price; The electricity price is low from 23:00 at night to 7:00 the next morning. If you can avoid peak electricity, you can save a lot of electricity.

8. Carbon compounds are called organic compounds, but some of them are similar to inorganic compounds, such as CO2, which is not considered organic. Generally, organic matter is combustible and insoluble in water (except ethanol).

9. How much is the electricity price in wusheng County, Sichuan Province in 2020? It should be in the hexagonal network from hexagonal to octagonal
