Method for designing cable path of nuclear power station

Abstract

The invention relates to the design technology of computer-assisted cable laying, in particular to a method for designing a cable path of a nuclear power station according to an established cable bridge network. The method comprises the following steps of: establishing the matching relation between a cable and a bridge, and establishing a one-to-one relation list between the type and series colorcodes of the cable and the type and series color codes of the bridge; modeling equipment at two ends of the cable in a database, and establishing data of the cable in the database according to a cable list; arranging reasonable approach points for the equipment at two ends of the cable according to the arrangement condition of the equipment, so that the approach points are used as a starting point and a terminal point in the cable path design process; and selecting the path reasonably according to a cable bridge network data model to lay the cable. When the method is used, the design of the cable path can be completed quickly, and problems of layer jump, the rationality of laying, work efficiency and the like in the conventional cable path design also can be solved.

Description

technical field [0001] The invention relates to a computer-aided cable laying line design technology, in particular to a method for designing a nuclear power plant cable path based on an established cable bridge network. Background technique [0002] The design of cable paths in nuclear power plants is a large and tedious task. Taking the Ling Ao Phase II Nuclear Power Plant with a reactor type of M310 as an example, there are more than 40,000 cables and a total length of about 2,800 kilometers. A large number of cables not only need to be laid reasonably according to the equipment layout, but also need to ensure the reasonable realization of their functions according to the isolation and fire protection requirements of the electrical equipment connected to them. [0003] Because of the arduousness and complexity of the cable route design work, it is obviously very difficult to carry out this design work manually. At present, the design of cable paths in nuclear power plan...

Problems solved by technology

[0008] III) Unreasonable jump layer of cable path

There are jumps with high spans in the design path of the cable, which usually causes difficulties in the construction of the cable during the actual laying process

This is usually due to the unreasonable path selection of the cable laying software during the automatic laying process, and the unreasonable selection of the cable path by the designer during manual laying
