Industrial enterprises are an important driving force in the development of China's national economy. The continuous growth of industrial development cannot be separated from the support of electricity. Due to different equipment and methods of electricity consumption, the loss rate of electricity in enterprises during use is not very low, but it is not easy to avoid. The consumption of electricity at low-voltage distribution terminals is very huge.
In order to strengthen the measurement, assessment, and management of terminal electrical energy, facilitate the use and modification of users, miniaturized rail mounted energy meters have emerged. Compared with traditional wall mounted energy meters, their measurement accuracy is higher, their overload and pressure resistance capabilities are stronger, their performance is more stable, and they consume less electricity. They are lightweight, small, and modular in structure, allowing the power management department to better monitor the electricity consumption of each user and achieve terminal distribution energy measurement.
Introduction to PART1 Rail type Energy Meter
At present, the installation of terminal energy meters generally adopts the traditional wall mounted installation method, which has the disadvantages of large volume and inconvenient installation.
The rail mounted energy meter adopts a modular design, which has the advantages of small volume, easy installation, and easy networking. It is easy to achieve terminal energy metering and facilitates the installation of energy meters for industrial energy metering systems for renovation.
The rail mounted energy meter is a new generation of miniature rail mounted energy meters, which adopts the standard DIN35mm rail mounted design, modular structure, and width matching with miniature circuit breakers, making it easy to install in the distribution box. The electric energy meter measures electrical energy and other electrical parameters, and can set parameters such as clock, tariff period, etc. It also has the function of outputting electric energy pulses.
Meanwhile, the rail type energy meter can use RS485 communication interface to achieve data exchange with the system. Rail mounted energy meters have the advantages of small size, high accuracy, good reliability, and easy installation. They are suitable for sub item measurement of electricity in government agencies and large public buildings, and can also be used for energy management assessment in enterprises and institutions.
Performance of PART2 Rail type Energy Meter
01 measures the total active energy and calculates it in reverse into the total energy;
02 Optional time slot compound rate electricity metering function;
03 supports RS485 communication interface and outputs charged energy pulses;
04 Current can be connected once or twice, with voltage signal power supply and no need for auxiliary power supply;
05 is compact with a width multiple of 18mm, perfectly matched with miniature circuit breakers, and comes with a lead seal to prevent electricity theft;
The installation method of the 06 DIN35mm standard guide rail makes it easy to fit into various distribution boxes.
Application of PART3 Rail type Energy Meter
With the increasing contradiction between power supply and demand, it is very important to strengthen power metering management. Rail type energy meters can not only achieve energy metering management, but also control user electricity consumption, promote tiered pricing, and measure electricity consumption in different time periods based on the actual daily electricity consumption of users, thus providing a basis for electricity price settlement.
By integrating energy metering, data collection, and data processing with a rail type energy meter, remote control of the meter can be achieved through a computer, effectively reducing manual labor and improving work efficiency. The rail type energy meter can ensure the balance of power supply and demand, ensure the safe and stable power supply of the power grid system, and has a wide range of applications in power metering management.
The Development Prospects of PART4 Rail type Energy Meters
Guided by the requirements of smart grid construction, realize the progressiveness of electric energy measurement, anti stealing, real-time monitoring, information interaction and automatic control; Realize the applicability of factors such as different environments and actual installation conditions; Realize uniformity in appearance, structure, and installation dimensions.
To achieve the goal of rational, economical, and safe use of electricity. The guideway watt hour meter can rely on the powerful digital information network and data analysis and processing system built by the "smart grid" to provide users with rich real-time power consumption information through the power information display screen, the Internet and various communication networks; At the same time, in the "smart grid" of information network architecture, the rail type energy meter also shoulders the task of data terminal collector, providing detailed measurement data to the "smart grid" continuously.
Standardize the unified standards for electricity meters. At present, there is a problem of inconsistency in the functions, rates, acceptance conditions, appearance dimensions, display reading content, voltage loss and current interruption judgment standards, and communication scale of electricity meters in various regions of the country. The standardized rail type electric energy meter will be more convenient for the production and circulation, installation and reading, calibration, and after-sales service of the meter. It will also facilitate the manufacturing and design of supporting equipment for electric energy meters, which can greatly promote the development and progress of the electric energy measurement industry.
Write at the end
With the popularization of the "smart grid", it will inevitably eliminate all traditional induction type energy meters and electronic energy meters that do not have bidirectional communication function and simple structure, and replace them with rail type energy meters that can achieve bidirectional communication between power supply enterprises and users. As a green, energy-saving, precise and fast new type of energy meter, it can effectively ensure the operating cost of the power grid, ensure the safety and reliability of the power grid, and lay a good foundation for the healthy and sustainable development of China's electricity.
