一种高压直流快速断路器
摘要：
本发明涉及一种高压直流快速断路器，属于高压、超高压直流输电技术领域。高压直流快速断路器由机械隔离开关、中低压直流断路器串联后与高压电子开关并联形成。该高压直流快速断路器串联于高压直流线路中，为高压直流设备及线路提供保护；当线路或直流设备故障时，高压直流快速断路器保护动作，使直流设备与线路迅速断开。
摘要（英）：

The invention relates to a high-voltage DC rapid breaker and belongs to the technical field of high voltage and super high voltage DC power transmission. The high-voltage DC rapid breaker is formed in such a way that a mechanical isolation switch and a middle and low voltage DC beaker are connected in series and then connected in parallel with a high voltage electronic switch. The high-voltage DC rapid breaker is connected in series with a high voltage DC line for protecting a high voltage DC device and a line; and in case of a line fault or a DC device fault, the high-voltage DC rapid breaker performs protective motion to quickly disconnect the DC device from the line.
