What are the Classification and Functional Characteristics of Smart Energy Meters？
Classification:
Smart watt-hour meters can be roughly divided into two categories: electromechanical integrated and fully electronic.
*Mechatronics
Mechatronics, that is, adding certain parts to the original mechanical watt-hour meter so that it cannot only complete the required functions, but also reduce the cost and be easy to install. Its design plan is to install a sensor device to become a smart meter that has electrical pulse output while mechanical metering without destroying the original physical structure of the current meter and without changing its national measurement standard. Synchronize electronic counting with mechanical counting, and its measurement accuracy is generally not lower than that of mechanical metering meters. This design scheme adopts the mature technology of the original induction watch and is mostly used for the transformation of old watches.
*Fully electronic
The all-electronic type adopts electronic devices with integrated circuits as the core from metering to data processing, eliminating the long-term mechanical parts used on the meter. Compared with the mechatronics electricity meter, the volume of the electricity meter is reduced, the reliability is increased, and it is more accurate. The power consumption is reduced, and the production process is greatly improved, and there is no need to produce in the original sense of the professional watt-hour meter factory. It will eventually replace meters with mechanical parts.
Features:
(1) Reliability
The accuracy remains unchanged for a long time, and there is no need for rotation, installation and transportation.
(2) Accuracy
Wide range, wide power factor, start sensitive, etc.
(3) Function
It can implement functions such as centralized meter reading, multi-rate, pre-payment, anti-theft of electricity, and meeting Internet access service requirements.
(4) Cost-effective
It is cost-effective, can reserve expansion functions, and is less affected by the increase in raw material prices.
Single Phase Smart Meter
(5) Alarm prompt When the remaining power is less than the alarm power, the meter always displays the remaining power to remind the user to purchase electricity; when the remaining power in the meter is equal to the alarm power, the power is tripped once, and the user needs to insert the IC card to restore the power supply. Electricity should be purchased in time.
(6) Data protection
Data protection adopts all-solid-state integrated circuit technology, and data can be maintained for more than 10 years after power failure.
(7) Automatic power off
When the remaining power in the electric energy meter is zero, the electric energy meter automatically trips and interrupts the power supply. At this time, the user should purchase electricity in time.
