Three-phase imbalance adjusting practical training device and using method thereof

Abstract

The invention relates to a three-phase imbalance adjusting practical training device which comprises a panel. A principal line analog line, a branch line analog line, a separation disconnecting link, a selection terminal, a principal line load monitor, a branch line load monitor, a user load simulator and a bus interface are arranged on the panel, the branch line analog line is the branch of the principal line analog line, the separation disconnecting link and the principal line load monitor are arranged on the principal line analog line, the branch line load monitor is arranged on the branch line analog line, the selection terminal is further arranged on the branch line analog line, the user load simulator is connected with the branch line analog line through a first adjusting wire and a second adjusting wire, the principal line load monitor, the branch line load monitor, the user load simulator and the selection terminal are all connected with the bus interface through wires via the separation disconnecting link, and the bus interface is externally connected with a control device. The three-phase imbalance adjusting practical training device is used by trainees for visually carrying out a three-phase imbalance analog operation, and has the advantages of being simple in structure, convenient to implement, convenient to operate, and visual in operation.

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...

AI Technical Summary

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 teaching and training In order to enable the operation and maintenance personnel to be proficient in the adjustment of three-phase load imbalance, in universities, vocational schools, training centers, etc. In theoretical calculations, whether the calculation results can realize the optimal adjustment of power load needs to be continuously explored and accumulated in actual work; Poor, in the actual operation, it is easy to cause safety accidents due to lack of experience or improper operation
