Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0041] Such as figure 1 As shown, the method for nuclear power plant fire protection analysis provided by the present invention comprises the following steps:

[0042] Step S1, establishing reference data.

[0043] Before defining the basic information, the reference data of the basic information should be defined first. These are part of the name of the basic information, including the fire space type, fire protection type, fire protection device identification and fire protection system.

[0044] The type of fire prevention space is to use the partition wall to prevent the fire from spreading, and to limit the fire to the space separated from other parts of the power station, so as to divide the fire prevention zone or fire protection zone. The type of fire prevention space is divided into four zones: SFS (safety fire zone), ZFS (safety fire zone)...

Abstract

The invention belongs to the technical field of computer aided design, and particularly relates to a method for nuclear power plant flameproof protection analysis. According to the method, a relational database is utilized to define flameproof space and flameproof protection; cable information, equipment information and other relevant information are extracted as input conditions for flameproof protection analysis; cable paths needing to be protected are analyzed and the heat dissipation quantity of power cables are computed by extracting fire load values of electrical equipment and the cables so as to help to complete fire hazard analysis and fire weak link analysis. Thus, work efficiency and design quality of computer-aided cable laying design are improved.

Description

technical field [0001] The invention belongs to the technical field of computer-aided design, and in particular relates to a method for analyzing fire protection by using a relational database. Background technique [0002] Fire protection is divided into fire hazard analysis and fire weak link analysis. The fire hazard analysis is to analyze the fire hazard, the fire load value of electrical equipment and cables, and the fire extinguishing function. Fire vulnerability analysis is to comprehensively and systematically solve and deal with an important consequence caused by fire: common mode failure of equipment, and ensure the nuclear safety function of the power plant. That is, it refers to the fire risk analysis of the layout of each fire prevention space and the fire load distribution of related rooms to identify potential common mode effects. Then perform functional analysis again, and take supplementary fire protection measures for the necessary potential common mode p...
