Title:
PASSIVE SEMI-CONTROLLED HYBRID DIRECT CURRENT CIRCUIT BREAKER AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/114599
Kind Code:
A1
Abstract:
A passive semi-controlled hybrid direct current circuit breaker and a control method therefor. The passive semi-controlled hybrid direct current circuit breaker comprises: a quick mechanical switch K, a resonant module, an energy-consuming branch configured to absorb a fault current, a thyristor T1, and a thyristor T2. Two ends of the quick mechanical switch K are both connected to a direct current circuit to constitute a main flow-through branch; the thyristor T1 and the thyristor T2 are anti-parallelly connected and then series-connected to the resonant module to constitute a transfer branch; the transfer branch and the energy-consuming branch are parallelly connected to the quick mechanical switch K; and the cathode of the thyristor T1 is connected to the quick mechanical switch K.
