Members of the committees serve voluntarily an
7、d without compensation. They are not necessarily members of the Institute. The standards developed within IEEE represent a consensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE that have expressed an interest in participating in the developm
8、ent of the standard. Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expre
9、ssed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at least every five years for revision or reaffirmation. When a document is
10、more than five years old and has not been reaffirmed, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. Comments for revis
11、ion of IEEE Standards are welcome from any interested party, regardless of membership affiliation with IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Interpretations: Occasionally questions may arise regar
12、ding the meaning of portions of standards as they relate to specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it is
13、important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to interpretation requests except in those cases where the
14、 matter has previously received formal consideration. Comments on standards and requests for interpretations should be addressed to: Secretary, IEEE Standards Board 445 Hoes Lane P.O.

IEEE Std C37.37-1996 is a loading guide that designates the continuous and emergency lo
20、ad current capabilities of air switches over a range of ambient temperatures. This is accomplished through a family of loadability factor curves. The Standards Committee on Power Switchgear, C37, which reviewed and approved this standard, had the following personnel at the time of approval: E. Byron

Overview 1.1 Scope
37、This loading guide applies to ac high-voltage air switches in excess of 1000 V rated in accordance with IEEE Std C37.30-1992.1 This standard does not apply to switches used in enclosures covered by IEEE Std C37.20.2-1993, IEEE Std C37.20.3-1996, IEEE Std C37.23-1987, IEEE Std C37.71-1984, and ANSI C
38、37.72-1987. Moreover, interrupter switches covered by IEEEP C37.39 are excluded from the scope of this standard. If an air switch is equipped with a load-break device or interrupter, it may not successfully interrupt currents above the nameplate rating. 1.2 Purpose The purpose of this guide is to ai
39、d users and manufacturers in the determination of: a)The allowable continuous current class (ACCC) designations. b)The continuous load current capabilities of air switches under various conditions of ambient temperature. c)The emergency load current capabilities of air switches under various conditi
40、ons of ambient temperature. 2.
