IEEE C 37.41-2008 高压(>1000 V)熔断器,熔断器和熔断,分配闭合式单极空气开关,熔断器断开开关以及与这些设备配套使用的熔断器连线和附件的设计试验
Design Tests for High-Voltage
(>1000 V) Fuses, Fuse and Disconnecting
Cutouts, Distribution Enclosed Single-Pole Air
Switches, Fuse Disconnecting Switches, and Fuse
Links and Accessories Used with These Devices
This standard specifies design test requirements for high-voltage (above 1000 V) fuses, distribution
enclosed single-pole air switches, disconnecting cutouts, fuse disconnecting switches, and accessories for
use on ac power and distribution systems. Devices with rated maximum voltages to 170 kV are covered.
The devices to which this standard applies are as follows:
a) Distribution and power class expulsion type fuses
b) Distribution and power class current-limiting type fuses
c) Distribution and power class fuse disconnecting switches
d) Item a) through item c) used in fuse enclosure packages
e) Fuse supports of the type intended for use with distribution and power class fuses, and fuse
disconnecting switches
f) Fuse and disconnecting cutouts
g) Disconnecting devices created by the use of a removable switch blade in a distribution or power
class fuse support
h) Distribution class enclosed single-pole air switches
i) Distribution class and power class expulsion, current-limiting, and combination types of
external capacitor fuses used with a capacitor unit, groups of units, or capacitor banks
j) Backup current-limiting fuses (“motor-starter fuses”) used in conjunction with high-voltage
Class E2 motor starters (see ANSI/UL 347-2000 [B1])1
k) Fuse links when used exclusively with distribution class and power class fuses, and distribution
class and power class fuse disconnecting switches
l) Item a) through item d) and item f) through item i) having integral load-break means
This standard specifies the minimum testing requirements for fuses and related devices. Such
standardization is needed to ensure uniform minimum product testing for devices within the document
scope. Test areas covered are based on historical experience.
