Smart digital measuring cabinet

Abstract

The invention discloses a smart digital measuring cabinet. The smart digital measuring cabinet comprises a cabinet body and a mounting structure arranged inside the cabinet body, and further comprises a plurality of digital electric energy meters with cabinet inserting structures or embedded structures, interchangers with cabinet inserting structures or embedded structures and industrial controllers with cabinet inserting structures or embedded structures. A plurality of inserting grooves are formed in the mounting structure, all of the digital electric energy meters, the interchangers and the industrial controllers are inserted into corresponding inserting grooves, and all of the digital electric energy meters are connected with the industrial controllers through the interchangers. The smart digital measuring cabinet is a novel electronic complete set of equipment with the functions of electronization, intelligentization, functionalization, integration and standardization integrated, there are qualitative differences compared with mere traditional mechanical measuring cabinets, and requirements for intelligentized connotation of an intelligent substation can be met, which is a radical innovation of electric energy measuring equipment and technology.

Description

technical field [0001] The invention relates to an intelligent digital metering cabinet, which belongs to the technical field of measuring equipment. Background technique [0002] There are more and more intelligent substations in the power grid, and the corresponding electric energy metering devices are composed of electronic transformers, merging units, network communication devices, and digital electric energy meters. The electronic transformer is the measurement and analog-to-digital conversion device of the electric energy signal; the merging unit is the secondary processing device of the transformer or transformer group, which accepts the analog or digital signal output by the transformer, and then packs the signal or data to generate IEC61850 protocol format message, and output to each bay layer equipment in the substation through point-to-point or networking; the digital electric energy meter is a pure digital signal processing and calculation equipment, IT terminal,...

AI Technical Summary

Problems solved by technology

This kind of structural metering cabinet not only has poor aesthetics, but also the bent optical fiber and wires also affect its life and reliability of operation, and it is very different from other professional functional screen cabinets in the same row, which is extremely uncoordinated, and it is increasingly technical. Backward, the cost of the hanging structure cabinet is high, and it does not conform to the principle of economic and environmental protection
