28、uide for Substation Fire Protection. Since the original edition of IEEE Std 979 (issued in 1994 and reaffirmed in 2004) was prepared, the body of knowledge on fire protection has increased significantly. This revision captures much of this knowledge and presents it for use by both the substation des

Overview 1.1 Scope The original guide (1994) was developed to identify substation fire protection pr

40、actices that generally have been accepted by industry. This revision includes changes in industry practices for substation fire protection. New clauses on fire hazard assessment and pre-fire planning have been added. 1.2 Purpose The purpose of the original guide (1994) was to give design guidance, f

41、ire hazard assessment, and pre-fire planning in the area of fire protection to substation engineers. Existing fire protection standards, guides, and so on that may aid in the design of specific substations or substation components are listed in Annex F. This revision updates that guidance. 1.3 Gener

42、al The guide outlines substation fire protection practices based on industry standards and good practices. It incorporates lessons learned from substation fires, substation fire protection research and testing, advancements in fire protection engineering practices, and changes in fire protection due

43、 to risk and IEEE Std 979-2012 IEEE Guide for Substation Fire Protection 2 Copyright 2012 IEEE. All rights reserved. environmental concerns. The guide provides design guidance in the area of fire protection for substation engineers and others involved in substation fire safety and protection. The pr

44、edominant dielectric insulating fluid for transformers is mineral oil, and mineral oil constitutes one of the primary fire hazards in the substation. Consequently, much of this guide addresses hazards and protection measures based on mineral oil fires. There are several alternative fluids with impro

45、ved fire safety properties (higher flash and fire points), known as “less-flammable” dielectric fluids, which have been introduced. Many of these fluids have been recognized as reducing the hazard and the risk of a fire occurring relative to mineral oil. Use of a “less flammable” fluid is one means

46、to reduce the risk of fire at a substation. See 8.4.2 and A.21 for additional information on these fluids. It is the intent of this guide that the analysis and decisions made may require the use of a team approach comprising various specialists. These specialists will be able to provide specific gui

47、dance on their areas of expertise; provide interpretation of the related codes, standards, and practices; and help formulate fire protection solutions. The following are some of the specialists that could be involved: Substation design engineers (civil, electrical, mechanical, and structural) Substa

48、tion operation and maintenance staff Fire protection engineers and specialists The local fire department The authority having jurisdiction over the substation Architects and code consultants This guide provides fire protection guidance for the following types of substations that have the principal p
