Problems solved by technology
[0005] Therefore, in power systems, industrial and mining enterprises, public facilities, intelligent buildings, etc., it is necessary to use power meters to measure and manage power quality, while traditional power meters can only be displayed on-site, requiring staff to go to the site to check one by one. Time-consuming and labor-intensive, and cannot effectively measure and manage power quality
[0006] For example, the commonly used three-phase distribution transformer monitoring instrument used to detect the user's current, voltage and other power supply parameters can only be manually copied due to insufficient equipment and technology, which is time-consuming and labor-intensive and the accuracy is not high, making the relevant voltage, current, etc. The power supply parameter information cannot be transmitted to the working platform of the power department in time
However, the existing remote transmitter does not have the monitoring function of power supply current, voltage, etc., and can only play a role of timing and simple information transmission.
With the continuous improvement of power quality requirements, the existing monitoring and information transmission methods can no longer meet the needs of development

The invention discloses an intelligent measure and control instrument comprising a power supply, a main control unit, a measure unit, a control unit, a storage unit, a real-time clock unit, a data transmission unit and a display unit. The main control unit, the measure unit, the control unit, the storage unit, the real-time clock unit, the data transmission unit and the display unit are powered by the power supply. According to the arrangement, power collecting, switching control, signal feedback and distribution box temperature changes are integrated, relative power such as electric power parameters is transmitted to a working platform of the electric power department in real time, real-time control of the field distribution device is achieved, in the cases such as overload voltage and current, remote control is facilitated, load is cut, electric power quality is improved, and energy is saved. The intelligent measure and control instrument has the advantages that modular design is adopted, size is small, mounting and maintenance are convenient, and high-speed, two-way, real-time and integrated real-time data collecting and remote-control is achieved.
Description
technical field [0001] The invention relates to a measurement and control instrument, in particular to an intelligent measurement and control instrument. Background technique [0002] In a modern industrialized society, electric energy has become an indispensable basic energy source. With the increase in the number of electrical equipment connected to the grid and the development of power load diversity, the power quality in the grid is more and more affected by electrical equipment. It's getting serious. [0003] Many new types of electrical equipment will inject various electromagnetic interference into the power system during operation, and the harm and impact on the safe operation of the power system and the normal work of user equipment will continue to increase. At the same time, various control systems, computer devices, Power quality sensitive equipment such as intelligent production lines of electronic products has higher and higher requirements for power quality. ...
