4、iIEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating Committees ofthe IEEE Standards Board. Members of the committees serve voluntarily and without compensation. They are notnecessarily members of the Institute. The standards developed within IEEE represen

5、t a consensus of the broadexpertise on the subject within the Institute as well as those activities outside of IEEE that have expressed an interestin participating in the development of the standard.Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that th

6、ere are no otherways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEEStandard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to changebrought about through developments in the state of th

7、e art and comments received from users of the standard. EveryIEEE Standard is subjected to review at least every five years for revision or reaffirmation. When a document is morethan five years old and has not been reaffirmed, it is reasonable to conclude that its contents, although still of someval

8、ue, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have thelatest edition of any IEEE Standard.Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affiliationwith IEEE. Suggestions for change

9、s in documents should be in the form of a proposed change of text, together withappropriate supporting comments.Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate tospecific applications. When the need for interpretations is brought to the

10、 attention of IEEE, the Institute will initiateaction to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it isimportant to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason,IEEE and the me

11、mbers of its societies and Standards Coordinating Committees are not able to provide an instantresponse to interpretation requests except in those cases where the matter has previously received formalconsideration.Comments on standards and requests for interpretations should be addressed to:Secretar

16、 IEEE Standard Requirements for High-Voltage Switches.)This standard is a revised and updated version of IEEE Std C37.30-1992 that incorporates improvements reflecting thestate of the art in high-voltage switch technology.a) By deleting the adjective “air” from “air switch,” the documents scope now

17、covers switches that are insulatedwith media other than air. This will provide a consistent base for applying and comparing the variousinsulating technologies available in switches today. However, this document focuses on air switches and willrequire considerably more development before it is the de

18、sired “generic” switch standard.b) Dielectric withstand voltages have been “unbundled” from rated maximum voltage, thus acknowledging thepractice of using many different dielectric withstand capabilities for the same operating voltage, dependingupon specific insulation coordination needs.c) Momentar

19、y current ratings are now defined in terms of a peak value, instead of the former “rms symmetricaltotal current.”d) The short-time ratings have been separated into a rated current magnitude and a rated duration of that current.e) Some higher temperatures are allowed in Table 2.f) Altitude correction

20、 factors are being developed by the C37.100.1 Working Group on Common Clauses.Because of the concurrent development of PC37.39, Proposed Standard for Interrupter Switches for AlternatingCurrent Rated Above 1000 V, the clauses dealing with interrupter switches were largely left unchanged. It is thein

21、tention of the working group to remove these clauses from this standard after PC37.39 is published.This revision is the consummation of the efforts of the C37.30 Revisions Working Group of the High-Voltage SwitchSubcommittee of the Switchgear Committee of the IEEE Power Engineering Society.

This includes such switch types as disconnecting, selector, horn-gap, grounding, etc., formanual or power operation. The following swi

37、tch types are not covered by this standard: distribution-enclosed, single-pole switches and distribution cutouts fitted with disconnecting blades; switches used in metal-enclosed gear coveredby IEEE Std C37.20.2-1993, IEEE Std C37.20.3-1987, and IEEE Std C37.20.4-1996; and switches used in pad-mount

38、ed switchgear covered by IEEE Std C37.71-1984, ANSI C37.72-1987, and PC37.73 (Draft 8, Feb. 95).NOTE PC37.39, Proposed Standard for Interrupter Switches, is currently under development. Upon its approval andpublication, all references to interrupter switches in this standard will be superseded.This

39、standard defines terms and words that uniquely apply to high-voltage switches and are not included in IEEE StdC37.100-1992. It also defines terms used for rating high-voltage switches and ratings that must be included onnameplates for high-voltage switches.2. ReferencesANSI C37.32-1990, American Nat

Service conditions4.1 Usual service conditionsHigh-voltage switches conforming to this standard shall be suitable for operation at or within their ratings, providedthata) The temperature of the cooling air (ambient temperature) is within the range of 3

47、0 C to +40 C.b) The altitude does not exceed 1000 m (3300 ft).c) The wind velocity does not exceed 37 m/s (80 mi/h).NOTE This wind velocity will produce a force of approximately 770 N/m2 (16 lb/ft2) of projected area on cylindrical surfaces(see NEMA SG 6-1995).4.2 Unusual service conditionsa) Equipm

48、ent that depends on air for its insulating and cooling medium will have a higher temperature rise anda lower dielectric strength when operating at higher altitudes than when operating at lower altitudes.b) For altitudes above 1000 m (3300 ft), correction factors should be applied to the switch ratin

Altitude-correction factors are being developed.c) Where other unusual conditions exist, they should be brought to the attention of those responsible for thedesign and application of the equipment. Examples of such conditions are:1) Contamination, such as damaging fumes or vapors, excessive or abrasive dust, explosive mixtures ofdust or gases, steam, or salt spray.2) Abnormal vibration, shocks, earthquakes, or tilting.3) Excessively high or low ambient temperatures.4) Unusual transportation or storage conditions.5) Unusual space limitations.6) Unusual operating duty
