Embodiment Construction

[0044] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0045] Such as figure 1 As shown, in Embodiment 1 of the present invention, a method for arranging the primary circuit trunk cable of a nuclear power ship is provided, and the method includes the following steps:

[0046] Step S1, determine the working cabin section, and obtain the current safety level of the backbone cables arranged in the working cabin section; wherein, the safety level includes non-dangerous, low-risk and dangerous;

[0047] The specific process is that the primary circuit backbone cable of a nuclear power ship refers to the power of the reactor cabin, auxiliary cabin, electrical cabin and connecting cabin, etc., from the generator to the main switchboard, and then from the main switchboard to the main electrical equipment. , Measurement and ...

Abstract

The invention provides a method for arranging primary circuit main cabLes in a nucLear power ship. The method incLudes the steps that a working cabin segment is determined, and the current safety LeveL of the main cabLes arranged in the working cabin segment is obtained; according to reLated structure information of the working cabin segment, the trend and instaLLing structure of the main cabLes in the working cabin segment are determined, the type and distance of aLL branched cabLes in the main cabLes are determined, according to the current safety LeveL of the main cabLes arranged in the working cabin segment, the trend and instaLLing structure of main redundant cabLes are determined, the distance of the main cabLes corresponding to the main redundant cabLes is determined, and the type and distance of aLL branched redundant cabLes in the main redundant cabLes are determined; according to the reLated information of the main cabLes in the working cabin segment and the main redundant cabLes, the cabLes are arranged in the working cabin segment. In the impLementation of the method, the designing requirements for the independency of a power suppLy circuit of nucLear safety LeveL redundancy equipment, the independency of power suppLy circuits of nucLear safety LeveL equipment and non-safety LeveL equipment and entity isoLation between the cabLes of different types can be met.

Description

technical field [0001] The invention relates to the technical field of nuclear safety, in particular to a method for arranging main cables of a primary circuit of a nuclear power ship. Background technique [0002] The ship's backbone cable refers to the power supply and control cables from the generator to the main switchboard, and then from the main switchboard to the main electrical equipment. Whether the design of the main cable route is optimized or not directly affects the reliability of the power supply of the ship's power system, and is also related to the economy of laying cables and the complexity of the ship's installation process. [0003] Due to the higher safety requirements of nuclear power ships, the large number of mechanical process equipment and pipelines, compact layout design is required, so the design method of the main cable of ordinary ships is not suitable for the design of nuclear power ships. However, the main cable design method of the primary ci...
