Performance Prediction Method Considering Shock Wave in Nozzle for High-Voltage Circuit Breaker
Get PDFInterrupting-performance indexes that reflect the physical properties of gas flow are proposed for a breaker terminal fault of a high-voltage circuit breaker. A method of evaluating the shock wave and flow velocity was developed that uses a theoretical equation of supersonic flow which takes into account the nozzle’s shape and stagnation pressure. The predicted flow velocities and positions at which the shock wave forms have strong correlations with the test results
