3.Working principle

3.1Working principle block diagram

The electric energy meter obtains voltage sampling signals from the voltage divider, current sampling signals from the current transformer, voltage current product signals from the multiplier, and then generates a counting pulse with frequency proportional to the product of voltage and current through frequency conversion.

3.2data processing

Electric energy metering pulses are sent through a photoelectric couplerCPUProcessed and stored in non-volatile storage after computationEEPROMIn the middle. Managed by a computer information system, throughICCard reader/writer, capable of writing a certain amount of power and monitoring requirementsICThe microprocessor system in the card input table, throughCPUAfter calculation, provide display, alarm, and cut-off status signals.

4.Installment and use

4.1 The electric energy meter can be installed and used after passing the inspection and being sealed with a lead seal before leaving the factory. Electric energy meters without lead seals or stored for too long should be re inspected by relevant departments before installation and use.

4.2The electric energy meter should be installed in a ventilated and dry indoor area, and can be installed at any position, but it is usually installed vertically. It is recommended to install it at a height of1.8The base plate for installing the electric energy meter should be fixed on a sturdy, fire-resistant, and vibration resistant wall.

4.3In places with pollution and potential damage to the structure, the energy meter should be installed in a protective cabinet.

4.4When installing wiring, follow the wiring diagram on the terminal cover of the electric energy meter or the corresponding wiring diagram in this manual. It is best to use copper connectors to prevent the electric energy meter from burning out due to poor contact.

4.5When using an electric energy meter in areas with frequent lightning strikes, lightning protection measures should be taken to avoid damaging the meter due to lightning strikes.

4.6The load capacity of an electric energy meter is0.05Ib~Imax(Direct access type) or0.02Ib~ImaxExceeding this load capacity between (connected through transformers) will result in inaccurate measurement of the energy meter or burning of the current coil due to heating.

4.7The reading of an electric energy meter connected through a transformer must be multiplied by the transformation ratio to obtain the actual amount of electricity.

4.8 After installing the table, use the settings card to set the table to the cost system table. Once successfully set up, the table belongs to the system and cannot be recognized by other systems.

4.9 After successful setting, the user can use the account opening card (on the authorized table). The first time the card is inserted, the battery level will automatically enter the table, and the battery level will be retrieved when the card is inserted again.

4.10 The power card function retrieves the stored power and reads it back into the system. Perform final processing.(To be increased)

4.11The meter reading card can read back the electricity in the meter, and each card can read248The total electricity consumption of the block meter. (To be added)

4.12Using one table with multiple cards: held by usersICThe card should be properly stored. If lost, the card should be replaced but the battery should not be replenished. The replacement card can be used to retrieve the battery.

4.13 The interval between each card insertion is10In seconds. Less and less10The second meter does not recognize. The RF card must display a success symbol before it can be removed to prevent battery loss.

4.14Preparation for purchasing electricity: Users bring their cards directly to the computer management office to purchase electricity.

4.15Electricity purchase method: When selling electricity, theICCard insertionICCard reader/writer, simultaneously operating the computer to encrypt and write user ID, pre ordered power, capacity limit method, and power limit, etcICCard.

4.16Electricity card usage: Insert the power purchase card into the card slot. If it is a valid power purchase card, the meter will automatically read the data into the meter. After waiting for a while, turn off the switch light to supply power. After use, please insert the card again to retrieve the battery and store it properly.

4.17Operation display: During the operation of the electric energy meter, the display screen shows

The remaining electricity in the table, total electricity consumption, and meter constant information.

Before operating the electricity meter, it is necessary to enter the system and record the meter number, meter constant, and other information for meter reading purposes.

6.4.19 The electricity meter should be loaded after it is fully closed, as direct loading will result in the lifespan of the relay.
