This do
5、cument is a new IEEE standard covering specifications for high-voltage distribution and power class expulsion, current-limiting, and combination types of external fuses for shunt capacitors. This standard was prepared by the IEEE Subcommittee on High-Voltage Fuses. Liaison was maintained with the In
6、ternational Electrotechnical Commission (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 cer
7、tain standards apply to all devices while other standards provide additional specifications for a particular device. For any device, IEEE Std C37.40-2003, IEEE Std C37.41-2000, plus an additional specification standard covering that device, constitute a complete set of standards for the device.aIn a
8、ddition, IEEE Std C37.48-2005 is an application, operation, and maintenance guide for all the devices, and IEEE Std C37.48.1-2002 provides additional guidelines for current-limiting fuses. The following standards make up this series: ANSI C37.42-1996, American National Standard Specification for Hig

Overview 1.1 Scope This standard establishes specifications for high-voltage (above 1000 V) distribution and power class expulsion, current-limiting, and combination-type external capacitor fuses and accessories, with rated voltages from 1 kV through 38 k
40、V, for protecting shunt capacitors complying with IEEE Std 18-20021and NEMA CP 1-2000. All of these devices are intended for use on ac systems. These fuses may be used with capacitor units, groups of units, or entire banks and include specific capacitor line group and capacitor unit fuse types as fo

43、n-type capacitor fuses type a), type b), and type c), respectively used in fuse enclosure packages (FEPs) 1.2 Background The expulsion, current-limiting, and combination types of fuses listed in 1.1 are similar to those covered in IEC 60549:1976.

44、282-2:1997. Use caution if devices specified and tested per IEC standards are compared to those specified and tested per IEEE or ANSI standards. Differences in test requirements between the two groups of standards may result in devices tested to IEC not being suitable for applications where devices
45、tested to IEEE/ANSI standards are required, or vice-versa. For definitions of fuse-specific terminology, see IEEE Std C37.40. In the headings and the text of this standard, there will be some areas where the information is included in brackets . The information in the brackets is a term used in IEC
46、standards that may be similar to the term used in this standard, a term that is common in some parts of the world, or a term that has been used previously in IEEE or ANSI standards. Caution is advised when making comparisons. Fuses used for the protection of shunt capacitors are either line group fu
47、ses or unit individual fuses. Line fuses are used for the protection of one phase of a capacitor bank that may have one capacitor unit or multiple capacitor units per phase. Line fuses are generally restricted to small capacitor banks. Some line fuses are not used only for capacitor protection, and
48、in many cases their major applications are for the protection of other devices or circuit sectionalization. Because of this, many specification requirements for line fuses are the same as those that are assigned to the particular fuse type for these other applications. Even fuses intended to be used
49、 only as capacitor line fuses will have some requirements that are similar to those used in these other applications. Therefore, for these specification requirements, this standard will refer to those requirements in the appropriate fuse-type specification standard. Unit fuses are used for the protection of one capacitor unit and are generally used in capacitor banks that have many capacitor units per phase. Unit fuses are used only for capacitor protection and are designed so that they are generally mounted on the bus bar of the c
