The invention is applicable to the technical field of reactor control and protection systems and provides a detector test device for a nuclear instrumentation system of a pressurized water reactor nuclear power plant. The device comprises a first power supply, a signal conditioning circuit and a signal processing circuit. The first power supply supplies power to the signal conditioning circuit andthe signal processing circuit. The signal conditioning circuit comprises a pulse adjustment circuit, a current amplification circuit and a positive/negative high voltage module. The signal processingcircuit performs operation processing on an amplified signal outputted by the signal conditioning circuit and outputs test data. Through the device, the off-line verification and copying of an RPN system detector can be realized, detector spare parts can be verified in advance, and the reliability of the detector quality is confirmed. 本发明适用于反应堆控制与保护系统的技术领域，提供了压水堆核电站核仪表系统的探测器试验装置，包括：第电源，信号调理电路和信号处理电路；第电源分别为信号调理电路、信号处理电路供电；
