Problems solved by technology

The single-phase smart energy meter in use has a short circuit between the zero line and the ground of the user and has to short-circuit the 3 and 4 terminal buttons of the energy meter (it is impossible for the power supply company to eliminate the short circuit fault of the zero line to the ground of thousands of households), so that the smart energy The meter loses the function of monitoring the zero line current

Abstract

The invention relates to a single-phase three-in electric energy meter for resisting technical electricity larceny, which fully solves the user problem of technical electricity larceny, avoids any meter dispute between a power supply enterprise and users and is convenient for the power supply enterprise to dispose the short-circuit-to-earth failures of indoor live wires of the users (a led-in live wire and a zero wire are exchanged, the indoor zero wire is short circuited to ground, and the electric energy meter does not meter more electricity). Inestimable economic benefits are brought to the power supply enterprise by the single-phase three-in electric energy meter, and the power supply enterprise needs to adopt reformed mounting and connecting technologies. A single-phase three-in two-out electric energy meter is mounted and connected by leading a ground wire in the electric energy meter (shown in figures 13 and 14), and a single-phase three-in one-out electric energy meter is mounted and connected by only providing an AC single-phase 220V live wire for users to use (shown in figures 15 and 18).

Description

technical field [0001] The invention relates to an anti-stealing electric energy meter. Especially a single-phase three-entry anti-theft electric energy meter. Background technique [0002] At present, single-phase electric energy meters are widely used in urban residents' daily electricity metering. With the continuous improvement of the cultural level of the general public in our country, more and more people know how to measure electric energy with single-phase electric energy meters. Selling electricity stealing technology, various high-tech methods of stealing electricity are constantly emerging among urban residents, causing the power supply provided by the power department to be lost in vain. On the premise of sealing the single-phase electric energy meter and installing the seal of the power supply department, a large amount of electric energy is stolen from the low-voltage power grid. We call it technology stealing electricity. [0003] The frame diagram of single...
