Problems solved by technology

[0007] With the rapid development of society, the growth of the national economy and the daily life of the people are increasingly inseparable from electric power resources. However, in the actual distribution process of electric energy, theft is often encountered. Enterprises bring greater economic losses, and also bring certain hidden dangers to the safety of electricity consumption in society

Abstract

The invention relates to the technical field of low-voltage line three-phase commutation, in particular to an intelligent control system for phase modulation between two phases of power supplies. Disclosed is a low-voltage automatic pre-distribution three-phase line balancing device based on Internet of Things and big data. The structure of the device is of a three-in two-out type, the input end of the device is connected with two phase lines and an N line of a three-phase alternating-current power supply, and the output end of the device is connected with a phase line and an N line of a usersingle-phase line. The low-voltage line three-in two-out type intelligent phase modulation device includes a three-way sampling module, an intelligent control module, a driving module, a dual-power module and an Internet of Things module. According to irregular dynamic changes of a load, tracking adjustment is made through analysis of the device, a user power supply is switched, a user line with acurrent sampling value smaller than a preset value is adjusted to be located on an optimal phase power supply to wait for power utilization, and user power utilization data is sent to a cloud database through the Internet of Things module to be stored.

Description

technical field [0001] The invention relates to the technical field of three-phase phase commutation of low-voltage lines, in particular to an intelligent control system for phase modulation between two-phase power sources in the communication mode of the Internet of Things. Background technique [0002] With the overall improvement of people's living standards in our country, high-power electrical equipment such as air conditioners, water heaters, and motors are continuously connected to residents, hospitals, schools, factories and other places, which makes the three-phase load of the low-voltage power supply system seriously unbalanced and partially overloaded. The phenomenon occurs from time to time, which not only affects the power supply capacity and quality of power supply system, but also increases the number of power system accidents and failures caused by it. The three-phase load balance of the existing low-voltage power supply system is still based on load detect...
