Abstract

The invention discloses an SOC technology-based single-phase guide rail type electrical energy meter, which consists of a shell, and a current and voltage acquisition circuit, an electrical energy metering chip, a communication circuit, a liquid crystal display and a power supply part which are all arranged in the shell. The SOC technology-based single-phase guide rail type electrical energy meter is characterized in that: the electrical energy metering chip adopts an SOC singlechip to meter electrical energy; and the back of the shell is provided with a guide rail groove and an elastic hook,wherein the elastic hook clamps the electrical energy meter with the guide rail groove on a 35mm standard guide rail. The SOC technology-based single-phase guide rail type electrical energy meter adopts the realization scheme of the SOC (System on chip) singlechip, and has the characteristics of high integration level, high reliability, good stability, high metering accuracy, rich functions and long service life.

Description

technical field [0001] The invention relates to the technical field of electric energy meters, in particular to a single-phase rail-mounted electric energy meter based on SOC technology. Buildings, airports, shopping malls, schools, docks. The invention also relates to a method for realizing the electric energy measurement of the electric energy meter installed on the single-phase guide rail. Background technique [0002] With the deepening of the reform of the power industry, especially the policy orientation of the power management department, the demand for single-phase multi-functional electric energy meters in power distribution terminals has increased significantly. [0003] The existing more common installation method of single-phase electric energy meter is wall-mounted, which needs to be equipped with a special electric meter box during installation, which has the disadvantages of large volume and inconvenient installation on site, and most of its implementation sc...
