Method, device and equipment for testing response time of nuclear reactor protection system

The invention relates to a response time testing method, device and equipment of a nuclear reactor protection system. The method belongs to the technical field of nuclear power testing, and comprises the following steps: responding to a response time test request for a nuclear reactor protection system, and obtaining a test item; and injecting a target test signal into the nuclear reactor protection system according to the test item, and recording the injection time of the target test signal. And then obtaining the output time of the nuclear reactor protection system for outputting the response signal based on the target test signal. And determining the response time of the nuclear reactor protection system through the injection time and the output time. Compared with the response time of the nuclear reactor protection system obtained through manual determination, the response time testing efficiency is greatly improved, the response time of the nuclear reactor protection system obtained through testing is mo
