The DC circuit breaker technology is one of the key technologies to build multi-terminal DC transmission network. Active DC vacuum circuit breaker (DCVCB) has become the research object. Based on the continuous transition model(CTM) and variable-step 4th-order Runge-Kutta method, sheath development stage during the post-arc dielectric recovery has been simulated and analyzed. Then the influence of...
Modeling DC vacuum circuit breaker (DC VCB), based on Kirchhoff's law, using the method of changing high order equation into a first-order equation, combining with variable step fourth order Runge-Kutta method, the numerical calculation and analysis of DC VCB in various stages during interruption are taken. And the absolute value of the product of the decline rate of current before current zero (CZ)...
