Working principle

A three-phase intelligent energy meter is composed of a measuring unit and a data processing unit. In addition to measuring active (reactive) energy, it also has two or more functions such as time-sharing and measuring demand, and can display, store, and output data.1The working principle of DTSD6607 electronic three-phase intelligent energy meter is shown in the diagram

As shown:

Figure 1 Working principle block diagram of three-phase intelligent energy meter485When the electric energy meter is working, the voltage and current are sampled separately by the sampling circuit and sent to the amplification circuit for buffering and amplification. Then, they are converted into digital signals by the metering chip, and the high-performance microcontroller is responsible for analyzing and processing the data. Due to the use of high-precision measurement chips, the measurement chip completes high-speed front-end sampling on its own, and the measurement algorithm is stable. The microcontroller only needs to manage and control the working status of the measurement chip. The microcontroller in the figure is also used for time-sharing billing and processing various input and output data, and completes time-sharing active and reactive energy metering and maximum demand metering functions according to pre-set time periods. It displays various data as needed, and uses infrared or

By setting the switching time in advance, it is possible to achieve unified time conversion between time period tables or time zone tables in use, avoiding customer disputes caused by inconsistent switching times. For example, when the user's time zone remains the same and the rate period needs to be adjusted, the meter's operating status can be read first, frombit02Understand which set of daily time slot meters are currently being used in the electricity meter, then program the unused daily time slot meters, and set the switching time for the daily time slot meters. This completes the entire modification operation, and the electricity meter clock will automatically switch when it reaches the switching time
