Abstract

In order to accelerate the fault current transfer rate of hybrid DC circuit breaker (HDCCB) and reduce the cost. A novel full thyristors HDCCB combining vacuum and gas integrated series switch is proposed in this paper, which accelerates the fault current transferred. Moreover, the breaking of higher current levels and lower cost by using the full thyristors to replace the IGBT and other power electronic (PE) devices are realized. The operation of proposed HDCCB is analyzed in detail, and the theoretical numerical model is derived. With the key parameters optimized in terms of the operation HDCCB, the breaking current capability and the effectiveness are verified by the simulation model. Based on this, preliminary tests from a developed low-power prototype are presented and verified the performance of the proposed novel HDCCB.
