Problems solved by technology

However, a large number of these devices are applied to a power distribution cabinet at the same time, causing many problems as follows: First, multiple devices need to collect the same signal, such as intelligent control instrument, intelligent measurement and control instrument and reactive power compensation control instrument, they It is necessary to collect three-phase voltage and current signals and state signals, and provide different measurement, monitoring and protection functions for power distribution through their respective algorithms, which doubles the workload of design, production, testing and maintenance of switches; secondly Because these smart devices provide communication interfaces for centralized monitoring, one or more communication networks are usually laid for each type of device for the communication of these devices, which makes the on-site construction workload huge and the reliability of the communication system is reduced. The difficulty of maintenance is greatly improved; again, smart devices are usually installed on the instrument door of the power distribution cabinet, and the external dimensions of the switch are determined, and the size of the instrument door is also quite limited; the emergence of more and more smart devices makes them The installation process on the power distribution cabinet has evolved into a puzzle challenge; therefore, the integration of intelligent equipment in the power distribution cabinet has become a mainstream demand, and the integrated intelligent power distribution measurement and control device also needs to have a reliable remote communication function, which is convenient for communication with the background system reliable communication from
