The embodiment of the invention discloses a reactor protection system channel response time testing device, method and system, and the device comprises a controller which is used for outputting a protection signal and a channel selection signal according to preset experiment data; the channel selector is used for gating an output channel from the N channel selection boards according to the channel selection signal, so that the protection signal is transmitted to the high-speed acquisition card through the output channel; and the high-speed acquisition card is used for recording the protection signal, receiving the reactor tripping signal sent by the DCS and comparing the time interval of receiving the protection signal and the time interval of receiving the reactor tripping signal so as to obtain the channel response time of the reactor protection system. According to the reactor protection system channel response time testing device, method and system disclosed by the embodiment of the invention, the reactor
