The IEEE develops its standards through a consensus develop-ment process, approved by the American National Standards Institute, which brings together volunteers representing variedviewpoints and interests to achieve the final product.

While the IEEE administers the process and establishes rules to promote fairness in the consensus devel-opment process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the information containedin its standards.Us

21、r Seismic Qualification of Class 1E Metal-Enclosed PowerSwitchgear Assemblies.)This guide complements ANSI/IEEE Std 344-1987, Recommended Practice for Seismic Qualification of Class 1EEquipment for Nuclear Power Generating Stations 101 by providing specific requirements and guidance for seismicquali
22、fication of metal-enclosed power switchgear assemblies.Metal-enclosed power switchgear assemblies fall into the category of complex devices as described in ANSI/IEEE Std344-1987 10; therefore, basic seismic qualification is dependent on test data. Analysis may be used in data reduction,reconciling r
23、esponse spectra, and evaluating changes. A method of combined test and analysis may also be used injustifying seismic qualification of similar equipment to the tested samples.It should be noted that while the primary purpose of this guide is for the application of metal-enclosed powerswitchgear asse
24、mblies in nuclear power generating stations, it is not restricted to this application. This guide may alsobe used as a guide in other applications in which the seismic response of metal-enclosed power switchgear assembliesis a consideration.At the time this guide was published, it was under consider

Scope and ReferencesThis guide provides requirements and guidance for the seismic qualification of metal-enclosed power switchgearassemblies including switching, interrupting, control, instrumentation, metering, and protective and regulating devicesmounte
44、d therein.1.1 ScopeThis guide may be used by equipment manufacturers to establish procedures that will yield data to substantiateperformance claims or by equipment users to evaluate and verify performance of representative devices andassemblies as part of an overall qualification effort.As used in t
45、his guide, the word switchgear shall mean metal-enclosed power switchgear assemblies with therequirements as defined in ANSI/IEEE C37.20.1-1987, Standard for Metal-Enclosed Low-Voltage Power CircuitBreaker Switchgear 4, ANSI/IEEE C37.20.2-1987, Standard for Metal-Clad and Station-Type CubicleSwitchg
46、ear5, and ANSI/IEEE C37.20.3-1987, Standard for Metal-Enclosed Interrupter Switchgear 6. By definition,metal-enclosed power switchgear assemblies include metal-clad switchgear, station-type cubicle switchgear, metal-enclosed interrupter switchgear, and low-voltage power circuit breaker switchgear. T
47、his guide does not cover metal-enclosed bus or control switchboards.Metal-enclosed power switchgear assemblies fall into the category of complex devices as described in ANSI/IEEE Std344-1987 10. Therefore, basic seismic qualification is dependent on test data. Switchgear assemblies have manydifferen
48、t types and arrangements of devices and components. It is neither practical nor necessary to test each uniqueconfiguration of devices and components, nor is it necessary to test a given configuration for every possible seismicenvironment. However, it is essential that each switchgear assembly used i
49、n Class 1E applications be seismicallyqualified for its environment, and this qualification must be based on data obtained by test. Analysis may be used indata reduction, reconciling response spectra, and evaluation of changes.A method of combined test and analysis may also be used in justifying seismic qualification of equipment similar tothe tested sample.2 Copyright 1989 IEEE All Rights ReservedIEEE C37.81-1989 IEEE GUIDE FOR SEISM
