Abstract
The utility model provides a three-phase multi-rate guide rail electric energy meter which includes a housing, a sampling module, a metering module, a CPU, a display screen, and a power supply module which are arranged in the housing, wherein the power supply module supplies power to the electric energy meter. The sampling module is connected successively with the metering module, the CPU, and the display screen. The middle of the back side of the housing is provided with a horizontal guide rail groove. A positioning sheet is arranged above the guide rail groove. Two elastic hooks are arranged below the guide rail groove. The elastic hooks lock the guide rail groove on a guide rail of a prior power distribution cabinet. The three-phase multi-rate guide rail electric energy meter adopts the guide rail installation mode, so the volume is small, and the meter not only can be arranged in a common cabinet, but also can be arranged in an embedded small power distribution cabinet, and consequently the installation and overhaul are facilitated.
