One second to understand the smart meter power

The smart meter is a smart terminal of the smart grid. It is not a traditional electric energy meter. In addition to the metering function of the basic electricity consumption of the traditional electric energy meter, the smart meter also has a plurality of directions to adapt to the use of the smart grid and new energy. Rate intelligence function, customer end control function, bidirectional data communication function of a variety of data transmission modes, anti-electricity stealing function and other intelligent functions.

The smart meter has only one LCD screen. If it is a single phase, it will directly display the total amount of power and the remaining battery capacity. Direct reading is sufficient. If it is an IC card meter, only the LED display is a single card, then there will be a small red dot on the meter. The red dot jumps to the total where it is used, and jumping to the rest is the surplus. Dual graphics card, read above or below. Three-phase prepaid meter direct in-line readings. The mutual meter reading is multiplied by the transformer magnification.

First, how to see the smart meter

First of all, there are four values ​​on the meter, namely, peaks, peaks, levels, and valleys. Look at some places on the Internet that may have only two or three smart meters. These four values ​​actually refer to the rate period. The lower tip is the highest because it represents the highest electricity price, which means that the peak electricity rate is the highest, and so on. This is actually because the power sector encourages us to design electricity during off-peak hours.

The electricity charge of each household is calculated based on the measurement of the jumps in these four periods. The final total electricity consumption is calculated based on the sum of these four values. How much electricity should be left? Smart metering There is a button that controls the 28 functions of the meter. Only need to press 2~5 times at a time (this is according to different regions), you can see the remaining electricity bill or remaining electricity.

Second, how to see the other meters

The first kind: The general straight-through single-phase electricity meter and three-phase electricity meter can read the figure directly and subtract the last reading to be the electricity of this stage. The straight-in meter is thicker, and careful observation has not passed. Transformer connection.

The second type: Three-phase electricity meter connected through the current transformer connection of three-phase electricity meter, meter wiring has 10 wiring, to observe the current ratio of the connected current transformer, current transformer nameplate, there is a number For example, the ratio of the number read from the meter to the current ratio multiplied by the current is the amount of electricity measured, and the loss and the line loss are added precisely.

The third kind: The single-phase electricity meter measures the electricity of three-phase electricity, the electric quantity reads the way is in progress the method of connecting the electric meter reads the figure on the electricity meter multiplied by 3, if the electricity meter connected through the transformer should read the electricity meter to multiply Multiply the transformer current multiple by three.
