All rights reserved. Introduction Over many years, standards covering interrupter switches have been developed in subcommittees other than the High Voltage Switch Subcommittee. As a result, different and sometimes conflicting requirements for interrupter switches have been developed. Where there is a clear need for different requirements in different applications, diverging standards are appropriate. However, where application requirements are similar, the body of standards should treat the requirements uniformly. As a result of this philosophy, the Switchgear Administrative Subcommittee passed the following motion at the May 1991 meeting in Fort Lauderdale. In an effort to promote a uniform approach to standards, the following policy is set: Future standards and revisions to standards that incorporate fuses, switches, circuit breakers, and/or reclosers and sectionalizers shall reference the basic fuse, switch, circuit breaker, and/or recloser and sectionalizer standard wherever possible and treat material differently only when there are unique application requirements. This standard was written to provide the basic standard for interrupter switches. As such, an attempt was made to encompass as many different types of interrupter switches as practical. This standard has also provided the opportunity to update and revise the general treatment of interrupter switches, and address newer technologies that are being used to provide switching functions. Part of the heritage of this document comes from the treatment of interrupter switches in other IEEE C37 standards. It is anticipated that material relating to interrupter switches, currently in the IEEE C37.30 series, will be removed from those documents when this document is published. Further, when this document is published, it is anticipated that other standards, not in the IEEE C37.30 series, will begin to reference this document, as outlined in the above AdsCom motion. Although this standard does not apply to circuit-breakers, circuit-switchers, or reclosers, standards for circuit-breakers, circuit-switchers, and reclosers should reference this document for their load-interrupting requirements. A further intent of this document is to provide test circuits to be used to establish ratings for common applications of switching devices not generally covered by standards. Although this document will be published before the work on IEEE Std C37.100.1 (Common Clauses) is finished, it is the intention of the Interrupter Switch Working Group to adopt or reference common clauses as they become available. Specifically the treatment of: Altitude correction factors, and Total temperature limits for contacts, connections, and insulation will conform to the Common Clauses Document. Conformance and field testing are not covered in this document. The user is referred to apparatus-specific test documents such as IEEE Std C37.41, ANSI C37.57, and ANSI C37.58. This standard has adopted the approach of many other standards in avoiding asymmetrical current ratings. For example, the traditional momentary (asymmetrical) current rating is now covered in the peak current withstand. Because of the lack of a need to calculate asymmetrical currents, and the common use of data This introduction is not part of IEEE Std 1247-2005, IEEE Standard for Interrupter Switches for Alternating Current, Rated Above 1000 Volts. 标准分享网 w w w .b z f x w .c o m 免费下载 v Copyright © 2006 IEEE.

Overview Scope This standard applies to switching devices, interrupters, and interrupter switches (as defined in IEEE Std C37.100) for alternating current, rated above 1000 V and used indoors, outdoors, or in enclosures for which a switching rating is to be assigned. While this standard covers the basic requirements of interrupter switches used indoors, outdoors, and in enclosures, other standards such as IEEE Std C37.20.2, IEEE Std C37.20.3, IEEE Std C37.20.4, and IEEE Std C37.74 also contain requirements for switches used in enclosures. This standard does not apply to load-break separable insulated connectors, which are covered by IEEE Std 386-1995 B8.1 This standard also does not apply to circuit-breakers, circuit-switchers, or reclosers. Purpose The purpose of this standard is to provide a basic standard for switches as defined in 3.5. The broad definition of a switch, given in 3.5, encompasses devices that meet the strict definition of an interrupter switch in IEEE Std C37.100, and also encompass devices that utilize insulating media other than air.
