<p>Disclosed is a simulated circuit breaker testing device for relay protection, comprising an acquisition module (1), a processor (2), an execution module (3), a display module (4), a setting module (6), an alarm module (7) and a power supply module (5). Under the control of an embedded program, the processor (2) receives and processes a relay protection device command input by the acquisition module (1), and instructs the execution module (3) to simulate the actual opening and closing operations of a circuit breaker and display relevant state changes. According to the set opening setting current and the closing setting current, the setting module (6) adjusts a command identification reference voltage in the acquisition module (1), and stores the set opening time and the closing time in the processor (2). The display module (4) displays the state of the simulated circuit breaker under the control of the processor (2). The simulated circuit breaker testing device can complete tests on single-phase tripping and closing and three-phase tripping and closing of relay protection apparatus, as well as an anti-trip test of a circuit breaker operation box. Furthermore, the device can more reliably simulate the relevant operation condition of an onsite circuit breaker with respect to the relay protection apparatus and debug the protection apparatus.</p> |
