Introduction This introduction is not part of IEEE Std C37.12-2008, IEEE Guide for Specifications of High-Voltage Circuit Breakers (over 1000 Volts). This guide is a revision of ANSI C37.12-1991. It reflects changes neede
3、d to coordinate with the IEEE Std C37.04, IEEE Std C37.04a, IEEE Std C37.06, IEEE Std C37.06.1, IEEE Std C37.09, IEEE Std C37.010, IEEE Std C37.011, IEEE Std C37.012, and IEEE Std C37.11. It also reflects the present circuit breaker manufacturing technology. This guide applies to all indoor and outd
4、oor ac high-voltage circuit breakers rated above 1000 volts and is issued as a guide for use in compiling technical specifications for the purchase of ac high-voltage circuit breakers. Primarily this guide applies to the Vacuum and Sulfur Hexafluoride circuit breakers. References to older technologi
5、es such as oil, air-blast, and air-magnetic circuit breakers have been deleted since these types are not presently being offered by manufacturers. This guide is intended to assist the user in specifying proper capabilities for circuit breakers when used in conjunction with IEEE Std C37.010 (applicat
6、ion of circuit breakers), IEEE Std C37.011 (transient recovery voltages), IEEES Std C37.012 (capacitive switching), and IEEE Std C37.015 (reactive switching). The imperative mode of the language used for example clauses is illustrative of that used in specifications. It does not imply that this docu
7、ment is anything other than advisory in its scope. The other change implemented in this guide concerns the title. It has been changed from “AC High-Voltage Circuit Breakers Rated on a Symmetrical Current Basis-Specification Guide” to “Guide for Specifications of High Voltage Circuit Breakers (over 1
8、000 Volts).” This change is consistent with similar changes in the title of other IEEE circuit breaker standards and guides. This guide contains clauses that may be used directly in a purchasers specification. Alternately, users may modify example clauses to form the basis of their own specification
9、. This guide does not contain all of the clauses that a purchaser may require for the purchase of high-voltage circuit breakers. For example, this guide makes no reference to commercial conditions that might be included in a purchasers complete specification. The guide also does not contain example
10、clauses that would provide all necessary requirements for every system application or physical installation. Users of the guide are cautioned to thoroughly review each individual application when preparing a high-voltage circuit breaker specification. Users of this guide are encouraged to review and
11、 thoroughly apply the high-voltage circuit breaker application principles identified in IEEE Std C37.010, IEEE Std C37.011, IEEE Std C37.012, and IEEE Std C37.015. These application guides have been developed to promote selection of appropriate circuit breaker features required for the successful ap
12、plication of high-voltage circuit breakers. Notice to users Laws and regulations Users of these documents should consult all applicable laws and regulations. Compliance with the provisions of this standard does not imply compliance to any applicable regulatory requirements. Implementers of the stand

IEEE does not, by the publication of its standards, intend to urge action that is not in compliance with applicable laws, and these documents may not be construed as doing so. v Copyright 2009 IEEE.
