Numerical Simulation of an Explosively Driven HVDC Circuit Breaker
High Voltage Direct Current (HVDC) circuit breakers have to suppress high values of currents at high voltages in absence of current-zero points. This makes the arc interruption more severe than the case of conventional AC networks. For circuit breaking in HVDC networks, a capacitor-inductor set has been inserted in parallel with the circuit breaker to inject reverse current to the interruption ...

متن کاملEXPERIMENT AND APPLICATION OF AN ANNULAR FOAM BREAKER FOR FOAM DRILLING FLUID (RESEARCH NOTE)
The annular foam breaker is one which uses the vacuum and shear force generated by the Coanda effect to break foam. Its effectiveness in destroying drilling foam has been test in wellbore flow simulation loop experimental stand. Experimental results showed that the operating pressure of the annular foam breaker should be larger than 0.6MPa and the stabilizers concentration of the foam drilling ...

متن کاملFlexible Pulsed Dc- Source for Investigations of Hvdc Circuit Breaker Arc Resistance
The paper discusses the design of a flexible pulsed current source needed for experimental research of switching arcs in HVDC circuit breakers with passive resonance circuits. The source drives a current pulse from a pre-charged capacitor and forms it using an IGBT switch operated at 10kHz. The current source will be used to measure stationary and transient UIcharacteristics of switching arcs i...
