All rights reserved.IntroductionThis revision of IEEE Std 693-1997 was developed as a recommended practice for the seismic design ofsubstations. This recommended practice emphasizes the qualification of electrical equipment. Nuclear Class
7、1E equipment is not covered by this recommended practice, but it is covered by IEEE Std 344TM.This recommended practice is intended to establish standard methods of providing and validating theseismic withstand capability of electrical substation equipment. It provides detailed test and analysismeth
8、ods for each type of major equipment or component found in electrical substations.This recommended practice is intended to assist the substation user or operator in providing substationequipment that will have a high probability of withstanding seismic events to predefined ground accelerationlevels.
9、 It establishes standard methods of verifying seismic withstand capability, which gives the substationdesigner the ability to select equipment from various manufacturers, knowing that the seismic withstandrating of each manufacturers equipment is an equivalent measure.This recommended practice is al
10、so intended to guide the manufacturers of power equipment in the seismicdesign and in demonstrating and documenting the seismic withstand capability of their product in a formthat can be universally accepted.Although most damaging seismic activity occurs in limited areas, many additional areas could
11、 experience anearthquake with forces capable of causing great damage. This recommended practice should be used in allareas that may experience earthquakes.It is the hope of those who worked on the development of this recommended practice that these standardmethods of verifying seismic withstand capa
12、bility will lead to better earthquake performance and to lowerqualification costs.Notice to usersErrataErrata, if any, for this and all other recommended practices can be accessed at the following URL: http:/standards.ieee.org/reading/ieee/updates/errata/index.html.

Overview 1.1 General This recommended practice provides minimum requirements for the seismic design of substations, excluding Class 1E equipmen
39、t for nuclear power generation stations. Seismic qualification of electrical equipment and its support is emphasized. 1.2 Scope The recommended practice contains recommendations for the seismic design of substation buildings, structures, and equipment. 1.3 Purpose This recommended practice is for ne
40、w substations and planned additions or improvements to existing substations. It is not intended that existing substations must be retrofitted to these recommended practices. For instruction on how to include this recommended practice in specifications, refer to 5.2. IEEE Std 693 is designed as an in
41、tegrated set of requirements for the seismic qualification of electrical power equipment. Users should use IEEE Std 693 as a whole. Do not modify or remove any requirement, except as allowed herein. If any part of this recommended practice is removed, not met, or reduced, then neither the user nor t
42、he manufacturer may claim the equipment is in compliance with IEEE Std 693 and should not attach the seismic identification plate to the equipment. The user is strongly urged not to modify any of the requirements herein, including increasing or adding to the requirements. The most important goal of
43、this recommended practice is to provide a single standard set of design recommendations for seismic qualification of each equipment type. Design recommendations consist of seismic criteria, qualification methods and levels, structural capacities, performance requirements for equipment operation, ins
44、tallation methods, and documentation. The intent of a uniform and consistent seismic qualification procedure is to reduce the cost for qualification of substation equipment, because the 1 Copyright 2006 IEEE. All rights reserved.

45、tations manufacturers can qualify their equipment once for each qualification level and eliminate specialized testing. It should also improve earthquake performance by establishing clear performance criteria that take into account the dynamic characteristics of substation equipment. Three qualificat
46、ion levels are defined. They are low, moderate, and high. The user should determine the desired qualification level when purchasing the equipment. See Clause 8. This recommended practice is divided into 8 Clauses (Clause 1 through Clause 8) and 22 Annexes (Annex A through Annex V). Clauses contain g
47、eneral seismic design requirements. Annex C through Annex P contain equipment-specific seismic design requirements and are located after the clauses. If the type of equipment to be qualified is not specifically addressed in Annex C through Annex P, the seismic design requirements of Annex B may be u
48、sed, if applicable. Annexes are titled normative or informative. Normative annexes are official parts of this recommended practice. Informative annexes include information only and are not an official part of this recommended practice. The following references are recommended for seismic design of s
