Problems solved by technology

The unbalanced three-phase load will also cause the loss of the low-voltage power grid, the loss of the transformer will increase, and the capacity of the equipment will decrease.
However, the actual three-phase circuit cannot be used for the unbalanced adjustment training of the three-phase load of the operation and maintenance personnel, and it is easy to cause the entire circuit failure or even a larger electricity accident due to the unskilled operation and maintenance personnel; in the actual

Description

technical field [0001] The invention belongs to the technical field of electrical training, and in particular relates to a training tool, in particular to a three-phase unbalance adjustment training device used in universities, vocational skills schools, training centers and other units to train students on electrical vocational skills and its Instructions. Background technique [0002] At present, in the three-phase four-wire circuit, the unbalanced load in the substation area is mainly caused by the single-phase load. The unbalanced three-phase load will also cause the loss of the low-voltage grid line, the increase of the transformer loss, and the reduction of the equipment capacity. Therefore, it is necessary to monitor and adjust the three-phase load. The low-voltage power distribution operation line distributes the power load according to the line capacity at the initial stage of erection, and in the later stage of operation, with the continuous increase of the power...
