Abstract
There is provided a direct current breaker based on vacuum magnetic blowout transfer and a breaking method thereof. The direct current breaker includes a first connection terminal, a second connection terminal, a main current branch, a transfer branch, an energy dissipation branch and a blowout unit. The main current branch is connected between the first connection terminal and the second connection terminal. During current conduction of the direct current breaker, current flows through the main current branch. The transfer branch is connected between the first connection terminal and the second connection terminal and connected in parallel with the main current branch. The energy dissipation branch is connected between the first connection terminal and the second connection terminal and connected in parallel with the main current branch and the transfer branch. The blowout unit is arranged between the main current branch and the transfer branch.
