Abstract

fetched live from OpenAlex

The arc nozzle of SF6 circuit breaker is thought as the kernel of arc quenching chamber,because of its controlling effect on gas flow property during the breaking process.The 252 kV SF6 circuit breaker is taken as the investigation subject.The influences on gas flow and dielectric strength recovery properties,which are caused by altering the angle of elevation,the dimension and the profile of arc nozzle of SF6 circuit breaker,were investigated.According to the theory of shock wave and the relation between flow velocity(Mach number)and ratio of section area in Laval nozzle,the influences on controlling effect of gas flow and dielectric strength recovery properties,which are caused by local expand-shrink nozzle andtwo-segment profile nozzle,were investigated.And the dielectric strength recovery properties of different profile and dimension of arc nozzle were compared.The result shows that the profile of arc nozzle affects remarkably dielectric strength recovery property during the breaking process.The conclusion is very valuable for the optimum design for arc nozzle of SF6 circuit breaker and miniaturization design for arc quenching chamber.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
