Three-in-one intelligent power distribution cabinet

Abstract

The invention provides a three-in-one intelligent power distribution cabinet, which is used for realizing the power distribution function which integrates digital intelligent management, safe operation, automatic control and on-site dynamic reactive power compensation to ensure the safe use of electricity of a power supply system, assure a user of safety, allow the user to use the electricity safely and maintain the safety of a power grid. The intelligent power distribution cabinet mainly comprises the following three parts: an intelligent monitoring part, an intelligent power distribution part and an intelligent dynamic compensation part, wherein the intelligent monitoring part is responsible for feeding slave station information back to a master station; the intelligent power distribution part conveys a master station instruction to a communication interface of a slave station to make the slave station actuate according to the master station instruction; and a control chip of the intelligent dynamic compensation part instructs silicon-controlled switched capacitors to perform dynamic compensation after detecting three-phase power factors to improve power factors and save energy.

Description

1. Technical field [0001] The technical invention belongs to the field of power distribution, and mainly relates to an intelligent power distribution cabinet capable of digital intelligent management, safe operation and automatic control, and on-site reactive power dynamic compensation (energy saving and consumption reduction). 2. Background technology [0002] Since the implementation of my country's "Village-to-Village" plan, rural areas have generally been connected to electricity. Due to the fact that my country's rural areas and natural villages are relatively scattered, the transmission of power lines is far away. The transmitted power is used after distribution, so that the power output can meet the needs of daily life and manufacturing, production, irrigation, etc. In one piece, a transformer is divided into 2-3 routes and the distribution distance is long; the transmission radius is large, resulting in large line loss and great management pressure. The seasonal load ...

AI Technical Summary

Problems solved by technology

[0005] 1. The scattered layout of farm houses cannot solve the problem in the short term, and can only be solved slowly by the construction of new countryside. However, the loss of power supply and distribution lines can be improved through effective reactive power dynamic compensation to improve power supply quality and power utilization;

[0006] 2. Most of the agricultural electrical equipment is 50HZ, 220V, which can easily cause three-phase imbalance on the line. The solution is to strengthen the distribution management of households and implement on-site phase-separated dynamic compensation (single-phase capacitor compensation);
