I don t have air conditioning, I don t use a computer, and I hardly watch the TV, is it normal to ha

If you don't use high-power electrical appliances in your home, the electricity is 439 a month, it must be abnormal, you can first check whether there are high-power electrical appliances in your home, for example, some things for electric heating, if you exclude high-power electrical appliances, or so much electricity, it must be ** wrong? You can contact the power supply department and ask them to come and check if there is a problem with your meter. Under normal circumstances, electricity means that there is no major problem, it is likely that it is still out of your home electrical appliances, maybe some kind of equipment is secretly using electricity, you don't know.

The monthly electricity consumption is 439 kWh, and the daily electricity consumption is kWh.

If you don't have high-power appliances at home, it is not normal to consume kilowatt hours of electricity every day.

It is advisable to test it yourself first:

1. Cut off the power supply of all electrical appliances in the house, observe whether the watt-hour meter is still running electricity, if it is obvious that the watt-hour meter is still running electricity, it may be connected to the wrong line, and other people's household appliances are connected to your home appliance meter;

2. Disconnect all the electrical appliances at home, write down the number of watt-hours of electricity, and then work the 1000-watt electrical appliances for one hour, and then see if the number of degrees of electricity is increased by 1 degree, and you will know how much the metering error is.

If the error of the watt-hour meter is large, you can apply to the local metrology supervision bureau to test the metering.

It must be abnormal, are the refrigerators and freezers not closed properly, and they have been refrigerated for a long time? There is also the water heater is not turned off. If there is no similar situation, then go to check the meter, and the Market Supervision and Administration Bureau can verify it.

Ask someone from the power bureau to check if the meter is normal. Is there a problem with the power supply circuit and electrical appliances at home.

This situation is definitely not normal, and it is recommended to look for the source of the leakage.

What about washing machines? What about refrigerator water heaters?

My house is up and down two a month, a big refrigerator, two rooms with electric lights and a living room, computer stereo for a few days, no air conditioner, water heater boils a tank of water at night, TV is basically not watched, range hood three meals open, if according to my standard, your electricity bill is indeed abnormal.

3: Connect and pair.

4: Enable software monitoring after successful pairing.

5: Start remote control.

Generally, it is transmitted through network cable or 485 port or wifi connection. It can be controlled by a computer, or simply controlled directly using the parallel port of the computer.

Hardware control modules and control software are required, which is not possible without an electronic foundation.

Such a high-tech thing has never appeared in Hollywood movies, let alone the Chinese market!

High movements, give up it It takes a lot of money and silver paper. You can do it if you have more money

It is necessary to have a software-controlled launcher.

This thing does exist, there is ready-made software to use, this software is called winlirc, I do the receiving line of this software, but not the transmission circuit part, if the transmission circuit is also made, you can achieve the function you said.

This software can learn and save the key codes of various remote controls in the computer, and then you can select the required ammonium key codes on the computer and then send them out.

This is the ** of the receiving line.

The receiving circuit is easy to do and not easy to tune, so I haven't done this part of the circuit.

As the refurbishment technology is becoming more and more mature, many businesses ask such professionals to repair the best TV, refrigerator, air conditioner and other household appliances, simple processing, and change the shell into a style that meets the latest trends. In this way, the old household appliances will be turned into new, and then sold to the people again at **.

China's urban and rural power grids use 220V50Hz alternating current, and now many electrical appliances have both alternating current and direct current. Air conditioning compressor, alternating current for fans. The control circuit should use direct current. The inside of a computer is generally direct current.

There are a lot of them. Laptops, digital cameras, electronic organs, mobile phones, PSPs, *** and other electrical equipment with adapters are used after turning AC into DC.

There are no appliances that are truly powered by direct current. AC power into DC power that enters the appliance.

Air conditioners, computers, TVs, etc. are all 220 alternating current power in the machine's internal power circuit converted into real current electricity to work, old-fashioned washing machines, refrigerators, etc. with motor properties and mechanical transmission control is 220 volt alternating current work.

Tape recorders, CDs, etc., but they all have to be alternating straight.

This depends on the power and frequency of use, computers and TVs must be turned on frequently, and air conditioners and heaters are used seasonally. If you say which one consumes electricity at the same time, which power is high, and which consumes electricity,

You add up the total power of these appliances and divide it by 220 to get the number of rated currents of the fuse, good luck.

C20 maximum go 4400W, air conditioning about 1000W, refrigerator working is 400, the computer is not easy to say, there are big and small, take the middle is 400 good, this is about 1800, what are the daily electrical appliances, and, the total open is a circuit breaker, should not be a leak protection, socket with leakage protection, air conditioning hang-up with 1P circuit breaker, if you have the ability to separate, don't have a leakage at home, some leakage insurance is very sensitive, there is a slight leakage will jump, especially air conditioning, the most prone to slight leakage,

The air opening capacity is not small, it may be that the air opening performance is poor or the wiring is not tightened, and the resistance is too large.

Generally, there are many types of electrical products, and the depreciation is about 1-5% per month. Take 3% more. For example, the air conditioner was bought for 3000 and used for a year (12 months).

3000*。For example, it is the fault of others that your air conditioner is damaged and cannot be repaired. People will give you 1,920 yuan according to this ratio.

And won't pay you for a new air conditioner.

My family spent 1280 yuan to buy a refrigerator in October 03, used it for 6 years and 3 months, and sold it for 280 yuan this year, according to this algorithm, I should have earned, and the actual virtual profit was 1280-(1280 * yuan, right?).

Latest depreciation years::

Depreciation period: 1) 20 years for houses and buildings;

ii) 10 years for aircraft, trains, ships, machines, machinery and other production equipment;

3) 5 years for appliances, tools, furniture, etc. related to production and business activities;

4) 4 years for means of transport other than airplanes, trains, and ships;

e) electronic equipment, for 3 years.

Therefore, how to calculate the depreciation cost of household appliances, such as TVs, air conditioners, and computer monitors for 3 years (when the annual enterprise income tax is settled, it is possible to be greater than or equal to 3 years.) The tax will be adjusted for less than 3 years).

These are generally depreciated according to 5 years, such as air conditioning 3000 yuan, the general net residual value is 5%, that month depreciation rate = 3000 * 95% 5 12 =
