Description

technical field [0001] The invention relates to a structure of a prepaid electric energy meter, in particular to a guide rail type three-phase prepaid electric energy meter. Background technique [0002] At present, most of the domestic prepaid energy meters are one-way wall-mounted or electrical cabinet-mounted, and the appearance is basically rectangular, and the volume is relatively large (the product is relatively small in size and has few functions). There are two ways to pre-store electricity charges in prepaid energy meters: one is to use electronic cards, namely IC cards, and the other is to use code input. Either way requires a pre-charged feed-in system and built-in circuit breakers, resulting in a larger meter. As disclosed in the Chinese patent CN2300107, "an electric card prepaid electric energy meter box" includes a box shell, an electric meter frame for installing an electric meter arranged on the box shell, and an electric meter box panel arranged on the fro...
