摘要（英）：

The invention provides a high-voltage heavy-current compound injection DC circuit breaker synthetic test circuit and method. The DC circuit breaker is a hybrid high-voltage DC circuit breaker. The circuit comprises a heavy-current test circuit, a hybrid high-voltage DC circuit breaker and a high-voltage test circuit. The heavy-current test circuit and the high-voltage test circuit are both connected in parallel with the hybrid high-voltage DC circuit breaker. The DC circuit breaker synthetic test circuit and method not only can check the passing current capacity and breaking current capability of the hybrid high-voltage DC circuit breaker, but also can check the platform voltage withstand energy of the hybrid high-voltage DC circuit breaker. The high-voltage heavy-current compound injection DC circuit breaker synthetic test method reduces test implementation difficulty and cost.
