Liquid arc voltage transfer based direct current breaker and use method thereof

A liquid arc voltage transfer based direct current breaker, comprising:

• a first connection terminal that is configured as an inlet wire of the direct current breaker,
• a second connection terminal that is configured as an outlet wire of the direct current breaker,
• a main current branch that is connected between the first connection terminal and the second connection terminal and includes a liquid break,
• a transfer branch that is connected between the first connection terminal and the second connection terminal and is connected in parallel with the main current branch, and
• an energy dissipation branch that is connected between the first connection terminal and the second connection terminal and is connected in parallel with the main current branch and the transfer branch, wherein,
• when current flows through the direct current breaker, the current flows through the main current branch, and the transfer branch is not conducted, and when a short circuit fault occurs in the direct current breaker, the liquid break opens, and the current is transferred to the transfer branch, and finally the current is forcibly transferred to the energy dissipation branch to complete the breaking.
