The invention discloses a method and a structure for installing a three-phase live wire. The invention aims to solve the problems of long construction time, high construction difficulty, insufficient electric energy monitoring precision and low safety in the installation of a three-phase meter in a live wire lapping manner. The device comprises an electricity box, a main switch, a three-phase electricity meter, an electricity meter body, a bottom plate, a mainboard placement area, a chip placement area and an interface placement area, the main switch and the three-phase electricity meter are installed in the electricity box, the main switch is connected with the three-phase electricity meter through a wire, the electricity meter body is installed on the bottom plate, the mainboard placement area is arranged at the top of the electricity meter body, and the chip placement area is arranged on the bottom plate. The chip placing area is arranged in the middle of the ammeter main body, the interface placing area is arranged at the bottom of the ammeter main body, the mainboard placing area is provided with an ammeter mainboard, the chip placing area is internally provided with a safety chip, a control chip, a metering chip and a reset chip, and the interface placing area is provided with an auxiliary terminal. The three-phase ammeter has the advantages of improving the safety and improving the accuracy of detecting the electric energy quality by the three-phase ammeter.
Description
Technical field [0001] The present invention relates to the field of three-phase electricity meters, in particular to a three-phase falling fire line installation method and structure. Background [0002] The expansion and new installation of the low-voltage industry is an important task of the power supply station. With the improvement of residents' living standards, both the increase in residential electricity consumption and the electricity demand of general industry and commerce are greatly improving. The workload of new installation and industrial expansion capacity of three-phase meter is increasing day by day. However, for the work task of installing a three-phase meter by overlapping the falling fire line, both the construction time and the construction process are higher than the installation and construction of single-phase meters. [0003] At present, the existing three-phase smart meter, its research technology for the working state of the power system is relatively w...
