| الوصف: | The change of the arc shape directly affects or determines the breaking performance of the arc extinguishing phase and the medium recovery phase after the arc. Through the diagnosis of the arc shape, the arc shape can be related to the performance of the switch. Therefore, the study of the arc shape plays a key role in the development of the large capacity switch. The collected arc shape change data was used to visualize the 2D dimensional arc model by extracting the edges and observing the changes of arc column diameter. The evolution of the arc was explained in detail from the three stages of arc initiation, stable ignition and quenching. From the results we can see: The upper edge position of the arc is maintained between 90-91 pixels, and the lower edge position satisfies the linear increasing relationship of the linear regression equation, and the correlation coefficient is greater than 0.95. The obtained 2D dimensional visualization data is in good agreement with the actual arc shape change, and can be used as a criterion for the quality of the switch. |
