Title:
DIRECT CURRENT CIRCUIT BREAKER
Document Type and Number:
WIPO Patent Application WO/2017/150079
Kind Code:
A1
Abstract:
This direct current circuit breaker 2 comprises a main circuit breaker 4 and a semiconductor switch 8. The main circuit breaker 4 is provided on a main path 6, and the semiconductor switch 8 is provided on an alternative path 10 parallel to the main path 6. This direct current circuit breaker 2 is configured in such a manner that, at opening time of the contact poles from the main circuit breaker 4, the semiconductor switch 8 is turned ON before the inter-contact voltage Vc arising between the two ends of the main circuit breaker 4 reaches a boiling voltage Vb.
