Description

The present invention relates to a kind of power metering device. In particular, the present invention relates to a new power metering device that includes a power input end and a load end of a kind of electric unit and an electric meter or the like installed between the two, and measures the power usage status on the electric unit or the power line route.

In the power supply system, after power is transmitted from the power company to the place of use, an electric meter as shown in FIG. 1 is installed at the front end of the user (the power company end), and the frequency of the power used by the user is determined. Measure and rely on the record of the meter clerk. In addition, if the user wants to know the state of his / her own power usage, the numerical value of the electric meter can be similarly examined. The electricity meter provided by the electric power company presents statistics of the total power consumption at the rear end (user end) of the electricity meter. However, if you want to know the detailed usage situation, turn off all the electrical products, turn on only the electrical products that need to be measured and observe the value of the electrical meter, or different electrical circuits extending from the total power source On the other hand, it is necessary to adopt a method of measuring each of the circuits, such as measuring the usage amount of each circuit one by one. In addition, this method must be performed separately in order to avoid affecting the overall power usage. In addition, when the voltage and current are measured using a three-use electric meter or a hook-type electric meter, another method that can know the power usage status can be typically described as follows. That is, using the principle of Ohm's law P = IE (power consumption = current × voltage), the voltage and current measured by the electric meter can be combined to know the power consumption status of the measurement object. However, it is necessary to convert to a familiar unit of charge calculation and multiply the obtained value by the time of use. For this reason, it is not easy for the user to know his / her own power usage status, and knowledge about power is required, and he / she does not have related equipment such as a three-use electric meter, a hook-type electric meter, and a wattmeter. Don't be. As energy consumption continues to increase, government agencies are calling for energy savings. The use of energy-saving products is one method, but the simpler method that can be tackled by the general public is that everyone can easily and specifically know the status of power use, thereby reducing energy consumption. Can be improved.
