In today's society, many electric energy meters have appeared, and most of these products are designed solely for the measurement of electric energy. However, with the development of society, the measurement of electrical energy needs to be centralized and multifunctional; therefore, the energy meter will also develop from a single energy measurement function to a multi-user energy meter .
Advantages of multi-user energy meters:
It has high measurement accuracy, strong overload capacity, low power consumption, stable and reliable performance, small size, light weight, and convenient operation; easy to implement management, and adapts to the needs of different user groups, such as industrial, agricultural, and civilian electricity measurement.
Technical characteristics of multi-user energy meters:
1. Centralized detection and display of electricity, the meter box is small in size, convenient for meter reading, and prevents theft of electricity. High range 10-50a, users do not need to replace the meter due to the increase of household appliances.
2, with power measurement function, visual display of the user's power load, to achieve on-site meter calibration. The case is stamped and formed with good sealing performance, with a lead seal, which complies with the national standard gb / t17215-2002.
3. The circuit uses three-phase power supply. Even if the power supply line is out of phase, the power consumption can be measured normally, and it has the functions of short-range infrared meter reading and remote computer network meter reading.
4. It adopts special terminal and double-bolt crimping wire for more reliable use. Adopt high-precision miniature power transformer, good electrical isolation effect, strong overload capacity and long service life. The power consumption of the whole machine is low, which is lower than that of a mechanical energy meter (<7va).
6. Wiring mode, multi-user energy meter can not only provide single-phase power supply for each household, but also provide three-phase four-wire power supply for each household. In other words, the electronic multi-user energy meter can be used as a single-phase active power energy meter and a three-phase four-wire active power energy meter. It has verification input and output terminals, which is convenient for on-site meter calibration. The connection terminals use double-bolt crimping method to avoid loosening and heating.
In recent years, with the development of technology, multi-user energy meters are not only metering tools, but more and more appear on the market as an energy-saving monitoring tool. Control power consumption, monitor power consumption, prevent power theft, etc. It can also be combined with other remote meters to truly form a remote intelligent system.
