Abstract

The invention provides a single phase electric energy meter. The electric energy meter comprises a meter shell, a circuit board, a relay, a current transformer, a single-phase junction box, a meteringmodule box and a programming button. The meter shell comprises a first pedestal, an upper cover installed on the first pedestal, an end cover installed on the first pedestal, and a flip cover installed on an outer surface of the upper cover. The upper cover and the first pedestal form a first cavity. The end cover and the first pedestal form a second cavity. The flip cover and the upper cover form a third cavity. The circuit board, the relay and the current transformer are installed in the first cavity. The single-phase junction box is installed in the second cavity. The metering module box is installed in the third cavity. The programming button is installed on the upper cover. Through the first pedestal, the end cover, the upper cover and the flip cover, the internal portion of the meter shell is divided into a plurality of cavities so that parts in the single phase electric energy meter can be conveniently dismounted and replaced.

Description

technical field [0001] The invention belongs to the technical field of electric power, and more specifically relates to a single-phase electric energy meter. Background technique [0002] Single-phase watt-hour meters are used in the measurement of active energy and are usually installed in various terminal distribution boxes, mainly including watch cases, circuit boards, relays, current transformers, junction boxes, metering module boxes and many other components. Various parts inside the traditional single-phase electric energy meter are installed in the watch case, the structure is messy and the assembly is complicated. When the single-phase electric energy meter fails, the internal parts are not easy to be identified, and it is inconvenient to disassemble and replace. Contents of the invention [0003] The purpose of the present invention is to provide a single-phase electric energy meter to solve the technical problem of inconvenient disassembly and replacement of var...
