Today, with the rapid development of science and technology, new energy meters have entered the homes quickly. The following describes the static energy meter and the prepaid energy meter with high technology content.
Static electric energy meter
The static energy meter is an advanced mechanism of electronic energy metering, inherits the advantages of the traditional inductive energy meter, adopts a fully shielded and fully sealed structure, has good anti-electromagnetic interference performance, and is energy-saving, reliable, lightweight, and highly accurate. A new type of electric energy meter with degree, high overload and anti-stealing.
The static electric energy meter obtains the current sampling signal by the shunt, the voltage divider obtains the voltage sampling signal, obtains the product of the voltage and the current through the multiplier, and then generates a counting pulse whose frequency is proportional to the product of the voltage and the current through the frequency conversion. The stepping motor is driven by a frequency division to measure the meter.
The static energy meter is divided into single-phase electronic type, three-phase electronic type and three-phase four-wire electronic type according to voltage, and is divided into single type and multi-function (active, reactive and composite type) according to the use.
The installation and use requirements of the static electric energy meter are almost the same as those of the general mechanical electric energy meter, but the wiring should be thick to avoid burning due to poor contact.
Electric card prepaid energy meter
The prepaid electric energy meter of the electric card is the electromechanical integration pre

A paid energy meter, also known as an IC card or magnetic card, is shown. It not only has the advantages of electronic energy meter, but also uses advanced microelectronic technology for data acquisition, processing and storage, and realizes the management function of paying for electricity first.
The prepaid electric energy meter of the electric card samples the voltage signal and the current signal through the resistor voltage dividing network and the shunting component, respectively, and sends it to the electric energy metering chip, and performs multiplication operation through differential amplification, A-D conversion and multiplier circuit inside the metering chip to complete The instantaneous power measurement of the measured electric energy is outputted by the filtering and digital and frequency converters, and the frequency pulse signal proportional to the average power of the measured electric energy is output, wherein the high frequency pulse output is available for verification, and the low frequency pulse output is output to the meter display. The amount of data is processed by the power and CPU for communication and copying.
The card prepaid energy meter also has single-phase and three-phase points.
