How many revolutions does the meter turn to one kilowatt hour of electricity? How many revolutions t

The size of the meter is different, and the number of revolutions is also different, for example, a 10 (20) A meter is 600 revolutions per kilowatt hour (kWh), so each revolution is 1 600 kWh.

It is different, the general meter is marked with the number of kilowatt-hour disc revolutions, for example, for every 3 ampere meter consumes 1 kilowatt-hour of electricity, the disc rotates 1800 times.

It depends on the number of amps your watch, the size of the watch is different, and the number of laps is also different.

According to the size of the meter, the 5A meter rotates 50 times to one kilowatt-hour, the 3A meter turns 120 times to one kilowatt-hour, and the 1A meter turns 400 times to one kilowatt-hour.

Household electricity meters must be inspected before leaving the factory, and a certain number must be taken. After the decimal point is the red letter is less than 1 degree, the decimal place is 1 degree, is 2 is the degree, before the decimal point is the black word is more than 1 degree, 1 is 1 degree, 2 is 2 degrees.

If there is a meter with a power multiple, the number before the decimal point is multiplied by the multiplier. If the multiplier is larger, the number after the decimal point is also multiplied by the multiplier. For example, the meter reading is, and the meter multiplier number is 40, and the reading multiplied by the multiplier number is the actual electricity consumption.

If the decimal point is not multiplied by the multiplier number, it is read 32 degrees less.

It depends on how big the meter is, and it says on it.

What can one kilowatt-hour of electricity do?

<> the specifications of each type of meter are different, the amount of electricity consumed by one revolution is also different. If the meter is marked with the character (2400rkwh), it means 2400 revolutions per kilowatt hour, that is, it consumes 2400 revolutions of one kilowatt hour, and the electricity consumed for one revolution is 1 2400.

Normally, the electricity bill is one kilowatt-hour, and the concept of one kilowatt-hour of electricity is: 1000W electrical equipment runs for an hour of electricity consumption.

Hypothesis: The air conditioner is calculated according to the wall-mounted type of constant base: the coefficient of 10 days per hour (the air conditioner is not operating at full load in most cases during normal operation); Computer: 10 hours per hour, 10 days 30 degrees.

Rice cooker: hour 1 hour 10 days 12 degrees; Kettle: 2kw hours 2 times 10 days 20 degrees; Subtotal of 10-day electricity bill: (Yuan (the national electricity price is not the same) Yuan.

Precautions for electricity use:

1. Don't buy "three nos."

Counterfeit and shoddy products, electrical products.

2. Know and understand the main power switch, and learn to turn off the main power supply in an emergency.

3. When using electrical appliances, there should be a complete and reliable power cord plug. Grounding protection should be used for electrical appliances with metal shells.

4. Switches and fuses cannot be installed on the ground and neutral lines.

It is forbidden to place the grounding wire.

It is connected to the water and gas pipes.

5. Do not touch the live equipment with wet hands, and do not wipe the live equipment with a wet cloth.

6. Don't connect the wires privately, and don't move the live equipment casually.

7. When inspecting and repairing electrical appliances, the power supply must be disconnected first.

8. When the power cord of the electrical appliance is damaged, it should be replaced immediately or wrapped with insulating tape.

r (denotes the energy meter.)

Turn 300 laps and walk, then lose the orange and turn 1 circle to take the potato 1

1 The electrical appliance consumes 12,000 J of electrical energy per revolution of the turntable.

The electrical energy consumed by the circle is 30*1 300=

p=w/t=

If the branch is rotated 30 times within 2min, the total power is 3000W

As shown in the figure, the black number of the meter is the integer degree, and the red number is the degree after the decimal point. The unit of measurement for an electricity meter is kilowatts per hour (kWh).

When the electric energy meter is connected to the circuit under test, there is alternating current flowing through the current coil and the voltage coil, and the two alternating currents produce alternating magnetic flux in their cores respectively; The alternating magnetic flux passes through the aluminum disc and induces eddy currents in the aluminum disk; The eddy current, in turn, is subjected to force in the magnetic field, which causes the aluminum disc to obtain torque (active torque) and rotate.

The greater the power consumed by the load, the greater the current through the current coil, and the greater the eddy current induced in the aluminum disc, the greater the torque that makes the aluminum disc rotate. That is, the magnitude of the torque is proportional to the power consumed by the load. The higher the power, the greater the torque, and the faster the aluminum disc will rotate.

When the aluminum disc rotates, it is affected by the braking torque generated by the permanent magnet, and the braking torque is opposite to the direction of the active torque; The size of the braking torque is directly proportional to the speed of the aluminum disc, and the faster the aluminum disc rotates, the greater the braking torque.

When the active torque and the braking torque reach a temporary balance, the aluminum disc will rotate at a constant speed. The electrical energy consumed by the load is directly proportional to the number of revolutions of the aluminum disc. When the aluminum disc rotates, the counter is driven to indicate the electrical energy consumed. This is the simple process of working with an energy meter.
