Abstract

The invention belongs to the field of nuclear power plant instrument control system and main control room control panel, and specifically relates to a nuclear power plant control panel physical isolation device and method, the device includes external incoming cables, terminal sets, closed metal wire slots, and metal hoses a. Metal hose b. Isolation keel and panel equipment; among them, the external incoming cable is connected to the incoming terminal of the terminal group, and the outgoing terminal of the terminal group is respectively connected to the closed metal trunking and the metal hose a, and the closed metal trunking It is connected with metal hose b, metal hose a and metal hose b are connected with one end of the isolation keel, and the other end of the isolation keel is connected with the panel equipment. The physical isolating device of the present invention utilizes the form of keel and detachable metal plate that comes with the equipment, which saves installation space, solves the problems of difficult installation of traditional isolating devices, reduces the requirements for the design of the plate structure, and shortens the processing and manufacturing cycle of the plate. Save on implementation costs.

Description

technical field [0001] The invention belongs to the field of nuclear power plant instrument control systems and control panels of a main control room, and in particular relates to an entity isolation device and method for a nuclear power plant control panel. Background technique [0002] At present, in the main control rooms of nuclear power plants under construction at home and abroad, operators are provided with a control panel based on conventional instruments as a means of monitoring the status of the power plant for the execution of safety and non-safety functions. As part of the instrument control system, when the monitoring equipment of redundant safety columns is installed on the same control panel, the requirements of the electrical equipment isolation criteria must be met, and the channel paths of different safety columns need to be physically isolated. For the actual effect of the physical isolation of the control panel, the domestic and foreign power stations in ...
