The utility model discloses a secondary circuit simulation device for a circuit breaker, and the device is used for solving the problems that a conventional simulation circuit breaker does not have a function of spring energy storage and cannot truly simulate the actual working conditions of a circuit breaker of a power system. The device comprises a local switching-on loop, a spring energy storage loop, a spring energy non-storage loop, and a spring energy storage indication loop. After the local switching-on loop is connected, the spring energy storage loop connected with the local switching-on loop is triggered. When the trip time of a time relay 1SJ of the spring energy storage loop does not arrives, the spring energy non-storage loop connected with the local switching-on loop is triggered, and controls the spring energy storage indication loop connected with the spring energy non-storage loop. The device can simulate the actual working conditions of the circuit breaker of the power system more truly, and has a function of simulating the spring energy storage.
