Abstract
Disclosed in the present application are a self-energy-taking hybrid direct-current circuit breaker and an application method therefor. In the self-energy-taking hybrid direct-current circuit breaker, a breaking branch is connected to a through-current branch in parallel, a first end of a grounding branch is connected to the breaking branch, and a second end of the grounding branch is grounded. When a direct-current system operates stably, the through-current branch conducts a steady-state running current of the direct-current system, and when the direct-current system breaks down, a self-energy-taking capacitor in the breaking branch assists a power electronic device in achieving the breaking of a fault current.
