DEVICE AND METHOD FOR BLOCKING HIGH VOLTAGE DIRECT CURRENT |
摘要 |
Provided is a DC current breaker having a high-speed breaking function appropriate to a voltage-type converter and a DC current breaking method. In addition, provided is a DC current breaker and a DC current breaking method capable of reducing cost of the breaker and securing economical competiveness by using a relatively simple configuration. The DC current breaker for breaking a DC current at the time of occurrence of an accident includes: a main conduction unit including three high-speed mechanical switches installed to be connected in series to a main conduction path for conducting a normal-operation-state current; a power semiconductor switch installed to be connected in parallel to one high-speed mechanical switch among the high-speed mechanical switches installed in the main conduction unit for current breaking of the main conduction unit; a capacitor installed on a circuit connected in parallel to the main conduction path; and a surge arrester installed to be connected in parallel to the capacitor connected in parallel to the main conduction path. The DC current breaking method uses the DC current breaker. |
