What parts do you need for the electricity meter？

In recent years, the construction scale of Smart Grid has been unprecedented, which has become an inevitable trend in the development of my country's power industry. As an important part of the smart grid, the development of smart meters plays an irreplaceable role in the growth of the smart grid. Then you want to know what's in the electric meter? Let me tell you about it!

First of all, the necessary components to form an electric meter include PCB-A circuit board, metering chip, internal memory, module, shunt/ct, infrared communication probe, reading information interface, micro switch, etc.

As long as there are electronic components such as integrated circuits, PCB-A circuit boards must be used for electrical interconnection between them. It is divided into 2 layers, 3 layers, and PCB-A circuit boards; the metering chip uses electrical signals Converted into data that can be read by the single-chip microcomputer, and then the single-chip microcomputer performs calculations to realize the measurement of electric energy; the internal memory is used to store the data read by the metering chip; the modules include capacitors, resistors (varistors), inductors, and transformers. In general, capacitors and inductors together form an RC anti-aliasing filter. The filter module generally needs to be placed after the electrical signal acquisition module to filter out harmonic signals. Resistor (varistor) protects the circuit from being burnt out by high voltage; shunts need to measure a large DC current, such as tens of amperes, or even larger, a few hundred amperes, there is no such a large range of ammeters for current For the measurement, this requires the use of a shunt. CT mainly provides bai secondary current for protection and measurement. Its primary side is connected to primary high-voltage equipment, and the secondary side is connected to secondary equipment. It can not only connect secondary electrical equipment such as measuring instruments and relay protection to high-voltage Electrical devices are effectively isolated to ensure the safety of workers. It can also standardize and miniaturize measuring instruments and relays, and can use small cross-section wires and cables for long-distance measurement; infrared communication probes can effectively realize meter reading and programming , Time calibration, data management and other functions; The read information interface receives the electricity consumption of the electronic meter to generate the output pulse du of bai, records the electricity consumption of the meter to realize the collection of electricity data information, and uploads the data to the concentrator or wireless handheld terminal; A micro switch is a contact mechanism that has a small contact interval and a snap-action mechanism, and uses a specified stroke and a specified force to switch the contact mechanism. It is covered by a shell and has a drive rod outside.

Of course, if you need the meter to be smarter, you can add some non-essential features that can improve the experience, such as: holding relay (remote on and off), LCD Display: display screen, LED indicator, button, battery, keyboard, CIU/ IHD home display, communication, meter box.

The holding relay can be turned on and off remotely as a switch device; the LCD Display display screen can display the data measured by the metering chip; the LED indicator has a pulse indicator, an alarm indicator, etc.; the button can adjust the display function, such as voltage, current, etc. ; The battery can keep the data in the meter after power failure and keep the data storage; the keyboard can query various items, the functions of recharge and input; CIU/IHD home display; communication can interconnect the meters and remotely read the meters; the meter box can effectively protect the meters Receiving shock and theft, reducing personal injury and death caused by improper operation.
