摘要（英）：

The invention discloses a full-scale high-voltage circuit breaker mechanism defect simulating and opening-closing coil current detecting device which comprises a high-voltage circuit breaker, a circuit breaker opening and closing controller, a first direct-current current transformer, a second direct-current current transformer and an opening-closing coil current detector.The circuit breaker opening and closing controller is connected with opening and closing controlling wires of the high-voltage circuit breaker separately; the first direct-current current transformer is clamped on a closing coil of the high-voltage circuit breaker and used for acquiring an induction current of the closing coil, and the output end of the first direct-current current transformer is connected with the opening-closing coil current detector; the second direct-current current transformer is clamped on an opening coil of the high-voltage circuit breaker and used for acquiring an induction current of the opening coil, and the outer end of the second direct-current current transformer is connected with the opening-closing coil current detector.The full-scale high-voltage circuit breaker mechanism defect simulating and opening-closing coil current detecting device has the advantages that various defects of the high-voltage circuit breaker can be conveniently, quickly, truly and reliably simulated, and the opening-closing coil currents of the high-voltage circuit breaker in various fault states can be conveniently studied.
