Problems solved by technology

The main disadvantage of the wall-mounted meter is that it is large in size and needs to be equipped with a dedicated meter box; the main disadvantage of the embedded meter is that it needs to open holes in the cabinet and equip it with a transformer, which requires a relatively large amount of work and is not necessary Easy maintenance
The inherent defects of the two installation methods make it impossible for electric energy metering to enter the power distribution terminal in a real sense, so that the requirements for sub-item metering cannot be fully fulfilled

Abstract

The invention relates to a miniature guide rail type installed single-phase kilowatthour meter, which comprises a shell and an internal assembly, wherein the shell structure is a miniature modulization structure, the width of the shell is integral multiples of the standard module value, a 35mm standard guide groove is arranged on the back of the shell, and the internal assembly is arranged in the shell. Compared with the prior art, the invention has the advantages of small size, convenience for installation and maintenance, simplified layout, reduced whole engineering cost, and the like.

Description

technical field [0001] The invention relates to a single-phase electric energy meter, in particular to a miniature guide rail type installation single-phase electric energy meter. Background technique [0002] In recent years, in order to meet the social needs of energy conservation and consumption reduction, local governments have successively issued new policy documents, requiring the realization of energy classification and sub-item measurement. At the same time, with the gradual deepening of power system reform, the demand for electric energy meters is increasing. [0003] There are two main installation methods for traditional energy meters: wall-mounted installation and embedded installation. The main disadvantage of the wall-mounted meter is that it is large in size and needs to be equipped with a dedicated meter box; the main disadvantage of the embedded meter is that it needs to open holes in the cabinet and equip it with a transformer. Easy maintenance. The inhe...
