Description

technical field [0001] The invention relates to the technical field of power transmission and distribution, in particular to a power electronic three-phase unbalance intelligent adjustment device. Background technique [0002] With the continuous development of my country's economy, electricity is becoming more and more popular as the main energy source, so the safety and maintenance of the power grid is particularly important. In my country's distribution network, there are a large number of three-phase imbalance problems. The three-phase imbalance is caused by the imbalance of the three-phase load and the asymmetry of the three-phase parameters of the system components. The state of the three-phase voltage balance of the power system is the power quality one of the main indicators. The three-phase unbalance will lead to additional heat and vibration of the rotating motor, increased magnetic flux leakage and local overheating of the transformer, increased line loss of the p...

AI Technical Summary

Problems solved by technology

The three-phase unbalance will lead to additional heat and vibration of the rotating motor, increased magnetic flux leakage and local overheating of the transformer, increased line loss of the power grid, and misoperation of various protection and automatic devices, etc. continuous normal operation

[0003] Most of the regulating devices currently in use use natural air cooling to dissipate heat, and the cooling effect is poor, so that the heat generated by the circuit will affect the electrical components, and rainwater and impurities can easily enter the device through the cooling holes, causing damage to the electrical components. The use of multiple electrical components leads to messy wiring in the device, which not only increases the difficulty of assembly but also makes it inconvenient to repair and replace components
