3 Terms and Definitions
Th terms and definitions defined in GB/T 2900.20-2016, GB/T 1984-2014 and GB/T 13498-
2017, and the following are applicable to this document.
3.1 General
3.1.1 high-voltage direct current circuit-breaker
A switching device that can make, carry and interrupt DC operating current, and can make,
carry and interrupt current under abnormal circuit conditions (for example, short-circuit
conditions) within a specified time.
NOTE 1.DC circuit-breakers generally include. main conduct branch, current transfer branch and
energy absorption branch. The main conduct branch is used to carry the DC operating
current, and with the cooperation of the transfer branch, it has the capability to interrupt
the main conduct branch current; the current transfer branch is used to transfer the current
of the main conduct branch to the energy absorption branch; the energy absorption branch
is used to absorb the energy stored in the system.
NOTE 2.in accordance with the type of interrupting components, DC circuit-breakers can be
divided into mechanical DC circuit-breakers, power electronic DC circuit-breakers and
hybrid DC circuit-breakers. In accordance with the direction of operating current, DC
circuit-breakers can be divided into unidirectional DC circuit-breakers and bidirectional
DC circuit-breakers.
