Neutron generator pup joint simulation device

The invention discloses a neutron generator pup joint simulation device. The electrical characteristics of the filament control circuit, the anode control circuit and the target voltage circuit are simulated through the simulation circuit, the same feedback signals are simulated and generated at the same time, and the signals are fed back to the control circuit short section through the connector,so that a neutron generator can be replaced to detect the whole system, and the risk of generating neutron rays is avoided. When the oxygen activation logging instrument is inspected and maintained,the neutron generator pup joint can be replaced to inspect and maintain the instrument, and the risk of mis-irradiation to personnel is eliminated. And meanwhile, as a technical means, the defect thatthe functions of the instrument circuit cannot be comprehensively detected under the original condition is overcome, and the detection of all the functions of the instrument circuit can be realized. 本发明公开的一种中子发生器短节模拟装置，通过模拟电路来
