Introduction This introduction is not part of IEEE Std C37.45-2007, IEEE Standard Specifications for High-Voltage Distribution Class Enclos
8、ed Single-Pole Air Switches with Rated Voltages from 1 kV through 8.3 kV. This standard is a revision of American National Standard Specifications for Distribution Enclosed Single-Pole Air Switches, ANSI C37.45-1981(Reaff 1992), to bring it up to date and in line with present-day requirements for hi
9、gh-voltage switches. This standard was previously developed by the NEMA High Voltage Fuse Technical Committee (SG2). As of 2003, the responsibility for this standard has been transferred to the IEEE High-Voltage Fuse Subcommittee. Liaison was maintained with the International Electrotechnical Commis
10、sion (IEC) during the development of the revisions in order to incorporate the latest thinking up to the time of publication. This standard is one of a series of complementary standards covering various types of high-voltage fuses and switches, arranged so that some of the standards apply to all dev
11、ices and other standards provide additional specifications for a particular device. The following standards make up this series: ANSI C37.42-1996, American National Standard Specification for High-Voltage Expulsion Type Distribution Class Fuses, Cutouts, Fuse Disconnecting Switches and Fuse Links AN

This rating provides an index of the ability of the device to withstand the electromagnetic forces that occur under maximum short-circuit conditions. To ensure that
42、 the device is tested with the proper severity, the first and second major current peaks shall be equal to or greater than those specified in IEEE Std C37.41-2000 Clause 10 for the rated momentary current of the device. The rated 3 s short-time withstand current test provides an index of the ability
43、 of the device to withstand the heat that may be generated under long-time short-circuit conditions. The two tests in item 1) and item 2) can be combined as described in IEEE Std C37.41-2000, Clause 10. It should be noted that for service conditions specified in 3.1.2 or 3.2 of IEEE Std C37.40-2003,
