Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention will be further described through embodiment.

[0019] The specific working process is as follows:

[0020] A closed / semi-closed building substation is selected as the evaluation object, based on image 3 described workflow.

[0021] 1 Form a fire risk assessment team. The evaluation team is generally composed of 5 to 8 people, and the number can be appropriately increased according to the evaluation workload. Evaluators should be proficient in the steps and methods of this evaluation system, as well as the current national fire protection laws, regulations and technical standards.

[0022] 2 Determine the evaluation scope based on the collected data. Understand the situation of the assessment object, determine the time required for the assessment and the number of staff.

[0023] 3 On-site assessment. It is mainly divided into two parts: the data access stage and the on-site inspection stage. ...

Abstract

The invention relates to a closed-type/ semi-closed-type building transformer substation fire risk assessment method. A closed-type/ semi-closed-type building transformer substation fire risk assessment system is constructed through the adoption of an analytic hierarchy process. Five secondary indexes and totally 28 tertiary indexes are included. The weight of each index is determined through an expert scoring form. According to a described assessment work procedure and through a final assessment score, a closed-type/ semi-closed-type building transformer substation fire risk assessment level is obtained and a rectification method is provided. According to the closed-type/ semi-closed-type building transformer substation fire risk assessment method, potential dangerous factors of an assessment object can be found out and analyzed and the fire risk magnitude of the assessment object can be measured. The assessment object can be improved accordingly, important guarantees can be provided for fire protection preparations, reduction of fire damages and the like, evidences are provided for the design, fire suppression, operation and maintenance and safety management of a closed-type/ semi-closed-type building transformer substation, and meanwhile, references can be provided for the fire risk assessment in other power typical sites.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering and fire risk assessment, and in particular relates to a fire risk assessment method for a closed / semi-closed building substation. Background technique [0002] A substation is a power facility in a power system that transforms voltage, receives and distributes power, controls power flow, and adjusts voltage. It is the gathering point for power transmission and distribution of voltage grids at all levels. In recent years, the scale of cities has expanded rapidly, and the demand for electricity consumption in cities has increased significantly. As a result, the number of substations has increased rapidly, and the requirements for substations in urban areas from the perspective of land occupation and city appearance are also getting higher and higher. A new type of substation—building substation came into being. It builds 110 kV or 220 kV substations near residential areas or even...
