Connection structure and connection method of nuclear power plant reactor protection system

Abstract

The invention relates to the technical field of a nuclear power station reactor protection system , and provides a connection structure of a nuclear power station reactor protection system and a connection method. In the connection structure, the nuclear power station reactor protection system comprises a signal logic processing apparatus and a tester. A plurality of rectangular first connector sockets are arranged on the signal logic processing apparatus, wherein each first connector socket is respectively and sequentially connected with a first connector joint, a cable and a circular second connector socket. The tester has a plurality of second connector joints connected with the second connector sockets. Compared with the prior art, contact failure of connecting with a signal logic processing device due to force-bearing deformation of inner pins of a connector joint can be eliminated, thereby ensuring normal communication and lowering risk of shutdown and specific signal error operation. The invention provides a connection method. The risk of shutdown and specific signal error operation due to test failure can be eliminated, and ideal test effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant reactor protection systems, in particular to a connection structure and connection method of the nuclear power plant reactor protection system. Background technique [0002] The system that generates protection signals consisting of all electrical devices, mechanical devices and lines (from sensors to the input of actuators) is called RPR (Nuclear Power Plant Reactor Protection System, in order to unify the technical terms, hereinafter collectively referred to as "Nuclear Power Plant Reactor Protection System ”), the nuclear power plant reactor protection system has a signal logic processing device. The reactor protection system of a nuclear power plant includes an emergency shutdown system, an ad hoc safety system and an ATWT (nuclear reactor protection function diversity and diversified protection) system. [0003] The main function of the nuclear power plant reactor protection syst...

AI Technical Summary

Problems solved by technology

[0023] The technical problem to be solved by the present invention is to provide a connection method and structure between the tester and the nuclear power plant reactor protection system, aiming to solve the existing test process, which is caused by the force deformation of the inner pin of the connector joint of the tester. After the signal logic processing device is connected, the contact is poor, so that it is impossible to inject signals into the signal logic processing device or collect signals.
