How to slow down the new electric meter?

Electricity is a commodity, and you pay for using it. This was a big sign on the street when I was a kid.

The meter is not allowed to be adjusted by the user.

Stop using your brain.

Paying attention to saving electricity is fundamental, benefiting the country, benefiting the people, environmental protection and energy saving. save money.

The electric meter is mainly composed of two parts: the measuring mechanism and the driving element. The measuring mechanism is the core part of electric energy measurement and consists of a turntable, a rotating shaft, a brake magnet, a gear and a counter. The driving element is composed of a voltage coil and a current coil, and is used to convert alternating voltage and current into alternating magnetic flux.

The working principle of the electric meter uses the principle of electromagnetic induction. The eddy current generated by the voltage and current coil on the aluminum disk causes the aluminum disk to rotate; the alternating magnetic flux interacts to generate electromagnetic force as a brake. Torque makes the rotation speed of the aluminum plate proportional to the load power, allowing the meter to calculate the amount of electricity.

According to the principle of the electric meter, we can know that changing the rotation speed, gear ratio, and changing the current, voltage, phase, etc. input to the electric meter can achieve the purpose of making the electric meter run slower. .
