Low-voltage automatic pre-distribution three-phase line balance box based on Internet of Things and big data

Abstract

The invention relates to the related technical field of power distribution equipment, in particular to a low-voltage power distribution box which is particularly suitable for a power distribution system for adjusting three-phase load uniform distribution in an Internet of Things communication mode. A low-voltage automatic pre-distribution three-phase line balance box based on the Internet of Things and big data is disclosed. The structure of the balance box is composed of a three-phase power supply input end, an Internet of Things intelligent machine group distribution module and a single-phase power supply centralized output end; the balance box is connected in series between a three-phase line on a low-voltage side of a transformer and a user single-phase electric meter box, an A-phase power supply, a B-phase power supply and a C-phase power supply are redistributed in the box by taking every two phases as a group, so that an input end of each intelligent phase modulation device is connected with a two-phase power supply, and an output end of the intelligent phase modulation device outputs single-phase power to the user electric meter box; and the data of a user before and afterpower utilization is sent to a cloud database for storage in real time.

Description

technical field [0001] The invention relates to the relevant technical field of power distribution equipment, in particular to a low-voltage power distribution box, which is especially suitable for a power distribution system that adjusts the uniform distribution of three-phase loads under the communication mode of the Internet of Things. Background technique [0002] At present, the optimal design of the distribution box is studied from the aspects of drainage, insulation, temperature control, maintenance, structure, etc., and the relevant three-phase phase modulation device is rarely designed in the box. Three-phase load balance is the basis of safe power supply. Unbalanced three-phase loads may reduce the power supply efficiency of lines and distribution transformers, or cause excessive overloading of heavy-loaded phases, which may cause a certain phase wire to burn out and a switch to burn out. Even serious consequences such as single-phase burnout of distribution transf...
