An Experimental Investigation into the Use of an SF6 Rotary Arc Circuit Breaker as an HVDC Switching Element
摘要
将一个未充电的电容器并联在断路器两端
当电容量为60μF、断路器的气体压力为0.3MPa时
旋弧式SF

断路器能够开断的直流电流约为360A
燃弧时间约为25ms。增大旋弧灭弧室的磁场强度有可能使开断电流进一步提高。
Abstract
Use an uncharged capacito r in parallel with a circuit breaker
the capacitance is 60μF
a breaking direct current about 360A and arcing time about 25ms could be achieved with a gas pressure of 0.3MPa by a conventional SF6 rotary arc circuit breaker.Use a high magnetic field
some improvements for DC interrupting performance can be made in this kind of breaker.
