Modular assembled electrical energy meter

Abstract

The invention relates to a power meter which can be assembled in a modular way, the power meter comprises: a power line access module which comprises a live line access component and a zero line access component, the two access components are respectively provided with an access end and an output end, the access end of the live line access component is connected with a live line in a power line, the access end of the zero line access component is connected with a zero line in the power line; at least one modular power metering device, each modular power metering device comprises a live line access end, a zero line access end and a live line output end for metering power values which are output by the live line access end and the zero line access end of the power line of each user; the output end of the live line access component is connected with the live line access end, the live line output end is connected with a live line output line; the output end of the zero line access component is connected with a zero line output line, the number of the zero line output line and the number of the live line output line are respectively corresponding to the number of the modular power metering device.

Description

technical field [0001] The invention relates to a power metering device, in particular to a modularly assembled electric energy meter which is formed by extending and connecting various modules centering on a standard metering module. 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 ...

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 at the power consumption site of the power sector. Often in order to achieve multi-functional requirements, it is necessary to add auxiliary equipment around the existing electric meter, resulting in power metering. The complete set of equipment is bulky and the production cost increases;

[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
