Modular assembled electrical energy meter

Abstract

The invention relates to an electrical energy meter which can be modularizedly assembled. The electrical energy meter comprises a power line access module and at least one modularized electrical energy meter, wherein the power line access module comprises a phase line access component and a zero line access component which are provided with an access end and an output end respectively; the access end of the phase line access component is connected with a phase line of a power line; the access end of the zero line access component is connected with a zero line of the power line; each modularized electric energy meter is provided with the phase line access end, the zero line access end, the phase line output end and the zero line output end and is used for metering the electrical energy values output by the phase line access end and the zero line access end of the power line of each user; the output end of the phase line access component is connected with the phase line access end; the phase line output end is connected with the phase line output line; the output end of the zero line access component is connected with the zero line access end; the number of the zero line output line is connected with the zero line output end; and the power line access module and the modularized electrical energy meter are arranged on a box body through modularized characteristic and are distributed.

Description

technical field [0001] The invention relates to a power metering device, in particular to a modularly assembled electric energy meter formed by expanding and connecting various modules centering on the idea of ​​modularization. Background technique [0002] With the development of the economy, the dependence of various fields of the national economy on electric energy continues to increase. In order to measure the amount of electricity consumption and realize effective management of the electricity consumption site, power metering equipment has emerged as the times require, and has become an important part of the field of electric power technology. A hot direction of continuous innovation. [0003] For the existing power metering equipment, it is mainly an electric energy meter, which can be a single-meter electric energy meter or a multi-meter electric energy meter. However, after years of power consumption management practice, it is found that the following defects still e...

AI Technical Summary

Problems solved by technology

[0004] First of all, due to the large number of manufacturers and the different specifications of the products produced, it is difficult to realize the unification of standards in the power consumption field of the power sector. Often in order to achieve multi-functional requirements, it is necessary to add auxiliary equipment around the existing modular electric energy meter , resulting in bulky power metering equipment and increased production costs;

[0005] Secondly, once the power department's management requirements or standards for power consumption sites change, the power supply department will need to make great efforts to replace and transform the complete set of power metering equipment, and the original products will have to be eliminated, which will greatly increase the cost of the power supply department. waste;

[0006] Thirdly, for the power sector, the existing complete sets of power metering equipment require a large amount of wiring and wiring during the application process, which requires a lot of labor costs. At the same time, the complex structural components bring great difficulties to the correct installation. It is not conducive to the realization of refined management on the site of power consumption, resulting in power consumption loss;

[0007]Finally, once the existing complete set of power metering equipment breaks down or needs to be replaced regularly, the entire meter can only be eliminated and replaced with new complete set of power metering equipment, resulting in Duplication of investment, increased costs for users and utilities
