3、ss Current-Limiting Type Fuses and Fuse Disconnecting Switches. This standard is a revision of the now-withdrawn standard, ANSI C37.47-2000, to bring it up to date and in line with present-day requirements for high-voltage current-limiting fuses and fuse disconnecting switches. This standard was pre
4、viously developed by the NEMA High-Voltage Fuse Technical Committee. 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 Commission (IEC) during the development of the revisio
5、ns in order to incorporate the latest activities preceding publication. The Switchgear Committee of the IEEE Power & Energy Society sponsored the published standard IEEE Std C37.100.1-2007 B5.a,bAlthough IEEE Std C37.100.1 is not specifically referenced in this document, any information that may app
6、ly to fuse devices has been incorporated herein. This standard is one of a series of complementary standards covering various types of high-voltage fuses and switches, arranged so that certain standards apply to all devices while other standards provide additional specifications for a particular dev
7、ice. For any device, IEEE Std C37.40, IEEE Std C37.41, plus any additional standards covering that device, constitute a complete standard for the device. In addition, IEEE Std C37.48 provides application, operation, and maintenance guidance for all the devices, and is supplemented by IEEE Std C37.48
8、.1, which is an operation, classification, application, and coordination guide for current-limiting fuses. At the time this standard was approved, this series was comprised of the following standards: IEEE Std C37.40, IEEE Standard Service Conditions and Definitions for High-Voltage Fuses, Distribut

Overview 1.1 Scope This standard establishes specifications for high-voltage (1000 V) distribution class current-limiting type fuses and associated accessories. All of these devices are intended for use on alternating current (a
45、c) systems. These specifications apply to the following specific types of equipment: a) Distribution class current-limiting type fuses and fuse units b) Distribution class current-limiting fuse disconnecting switches c) Item a) and item b) used in fuse-enclosure packages d) Fuse supports, fuse units
46、, refill units, and fuse mountings of the type intended for use with distribution class current-limiting type fuses, and fuse disconnecting switches. e) Disconnecting devices created by the use of a removable switch blade in a distribution class current-limiting type fuse support. 1.2 Purpose Standa
47、rd specifications for the devices covered by this document are necessary to maintain consistent development and application of these devices by manufacturers and users of these devices.

48、e Fuses and Fuse Disconnecting Switches 2 Copyright 2012 IEEE. All rights reserved. 1.3 General information Due to the wide variation in fuse types, interchangeability guidelines have little meaning. Standard ratings such as “C,” which is defined in this standard, only provide a basic level of time-
49、current characteristic (TCC) conformance and do not provide enough information to establish proper application and coordination of fuses. This is particularly true when different fuse types or fuses from different manufacturers are being applied together. Published information, such as current ratings and TCC curves, should be used to select fuses, following manufacturers recommendations. If there are specific questions, the manufacturer should be consulted. 1.4 Background Some of the current-limiting type fuses listed in 1.1 are si
