We all know how much electricity the dormitory uses every day, and we are curious about how much electricity the dormitory uses every day. Let's take a look at the information about how much electricity the dormitory uses every day.
How many kilowatt-hours does the dormitory use a day? 1 Generally, the lights are turned off at 7 o'clock, which seems to be 20 degrees.
The electricity consumption in the dormitory shall not exceed1000 w w.
1, the power supply circuit of school dormitory is designed and installed according to small demand and low power. There are many people living in the student dormitory. Generally, the maximum load that each dormitory can bear is about 1 1,000 watts (the design of each school is different), which can only meet the daily electricity consumption of lighting, water dispensers and computers.
2. The power supply line of the student dormitory uses wires instead of cables, and the distribution facilities are designed and configured according to civil lighting standards, and high-power electrical appliances are not allowed.
3, the use of high-power electrical appliances is likely to lead to wire overload, resulting in an increase in current, wire heating, the more overload, the faster heating. The allowable temperature of wire insulation is generally 60℃. If the line is overloaded for a long time, the calorific value of the line will increase and the insulation layer will accelerate aging. When the temperature is higher than 250℃, the insulation layer will spontaneously ignite and separate from the wire, resulting in short circuit and fire accident.
4. The dormitory is crowded, and the consequences of accidents are unimaginable. Throughout the world's major accidents, the losses in crowded public places are extremely heavy.
It is not appropriate to directly destroy the prohibited electrical appliances in university dormitories;
Whether the dormitory can use high-power electrical appliances has always been controversial. Some people think it should be banned; Some people think that students are in need, which shows that schools should strengthen logistics support, which is a more effective way to solve the problem.
The safety hazards of high-power electrical appliances should not be underestimated, but the school will destroy all the "dormitory contraband", which may also bring other problems. For a long time, some legitimate and good intentions in the management of individual schools have not produced the same result: concentrate on class, students' mobile phones have been confiscated or even broken; In order to urge students to study by themselves, the dormitory was forcibly cut off; In order to ensure the number of students attending the class, students are required to sign in, otherwise, the qualification for evaluation will be cancelled.
How many kilowatt-hours does the dormitory use a day? How many kilowatt hours do you need?
An hour of 2000w electricity is 2 kWh, and the electricity charge is basically around 0.56 yuan/kWh, which means that the electricity charge for an hour of 2000W use is 2*0.56= 1. 12 yuan.
W=Pt
Work = power * time.
When 1 kwh = 1 kwh, an electrical appliance with a power of 1 kw will consume 1 kwh. The calculation formula is: electricity consumption (kWh) = power (kW) × service time (hours).
Calculated by kWh usage 1 kWh, 2000W* 1 hour/1000 w = 2 kWh.
Extended data:
Calculation method of electricity fee:
1, calculated according to the maximum power demand.
2. According to the electricity consumption.
Electricity price difference.
Electric power can be divided into thermal power (including nuclear power, etc. ) and hydropower (including wind energy, etc.). Different kinds of electricity mean different production processes and their production costs are also different. Under the condition of the same utility but different cost, the value of different kinds of electricity determined by the utility-cost ratio is different.

According to kwh = 1 kwh, 2000W power 1 hour is 2 kwh, and if calculated according to 0.56 yuan, it is 1. 12 yuan. In China, different regions have different tariff standards. The price of electricity for ordinary residents is about 0.56~0.62 yuan per kwh, and that for industry is 0.86~ 1.80 yuan per kwh. So it depends on what kind of users use electricity.
When most of us talk about electricity charges, we will think that the price of electricity charges is uniform. In fact, there are still many differences, such as civil electricity, industrial electricity and commercial electricity. Even the price of electricity we rent is different from that of residential electricity. There are also different charging standards for electricity in different seasons. At present, there is a ladder price for electricity consumption, which depends on the user's electricity consumption level.
So we seem to be simple 1 kwh, and the difference is still very large. The general price of electricity for urban residents in China is 0.52 yuan -0.62 yuan 1 kwh, while the price of industrial electricity is 0.86- 1 kwh, and that of commercial electricity is generally 1 kwh. The current ladder electricity price is calculated as follows: users use 0-260 kWh per month, and the electricity price is 0.52 -0.62 yuan 1 kWh; If the user uses 20 1-400 kwh of electricity every month, the price per kwh will be increased by 0.05 yuan; If users use 40 1 kwh of electricity every month.
At present, many cities divide peak and valley electricity prices. The peak-valley electricity price is 0.56 yuan 1 kwh, and the valley electricity price is 0.28 yuan 1 kwh. For example, the electricity consumption of residents in Shenzhen is also calculated according to the ladder electricity consumption. The greater the electricity consumption, the more expensive the electricity bill. The Price Bureau stipulates that the electricity consumption of residents is 0.68 yuan/kWh, and the electricity consumption of residents in the city is once in 0.7 yuan.
