With the improvement of the quality of life, the electricity consumption at home is also increasing. The huge monthly electricity bill makes many people feel distressed. After the IC card meter became popular, there were reports of electricity theft. method, so some people want to try it. So what are the dangers of stealing electricity from IC card meters, and how to save electricity reasonably? Let the editor explain it to everyone.
There are dangers in stealing electricity from IC card meters
1. Hazards in stealing electricity from IC card meters
The inside of an IC card meter is composed of a base meter, a digital display, and a relay switch , main control microcontroller chip, ESAM module and IC card interface. The work is mainly completed by two functional systems: measurement system and microcontroller processing system.
Measurement system: It is a single-phase electronic energy meter. The working principle is: voltage sampling is completed by the voltage divider, and current sampling is completed by the sampling resistor. The sampled voltage and current signal is converted into a power signal by the multiplier. After V/T conversion, the counter is driven to work and the pulse signal is Enter the microcontroller system. Users need to pay money to purchase electricity at the power supply department. The purchased electricity is written into the user's electricity card on the selling motor, and is transferred from the electricity card to the meter. The electricity card has been encrypted multiple times to ensure reliable use by the user. When the purchased power is used up, the relay in the meter will automatically cut off the power supply circuit.
In order to save electricity, some people use household electric meters to steal electricity while using electricity. This saves the original neutral wire and makes a ground wire by themselves, which means using an electric meter. At the same time, use the ground wire you made yourself so that the current does not go back through the neutral wire and the meter will not run.
How to save energy reasonably
This is very dangerous. If the electric energy meter is not modified and the original correct connection method is maintained, then "adding a ground wire" and using it as the neutral wire will not prevent the meter from running. On the contrary, it will cause great danger due to this connection method, which may Seriously endanger equipment or personal safety!
2. How to save electricity reasonably
It is far better to save electricity reasonably than to steal electricity. After all, it is illegal to insert a card meter to steal electricity. There are many ways to save power by plug-in electricity meters, such as keeping electrical appliances in standby mode; buying fans of good quality (high efficiency) and not trying to be cheap. A 30 yuan one cannot be compared with a 130 yuan one, even if the wattage is the same. It can be used. Do not keep the rice cooker warm for a long time, use the residual heat to cook rice. Replace white lamps with highly efficient and energy-saving lighting fixtures. Also replace your energy meter if it is too old. In addition, computers also consume electricity. A large amount of electrical energy is converted into heat energy, and 400W of electrical power is not enough.

The above is the main content of whether it is harmful to steal electricity from IC card electricity meter and how to reasonably save electricity. There are too many things in home life, so of course we must make it easy for ourselves. Even better, I hope the above content can help you who love life.
