本标准规定了额定电压为1 kV至38 kV的高压（1000 V以上）配电和功率等级排除、限流和组合型外部电容器熔断器及附件的规范，用于保护符合IEEE Std 18？的并联电容器-20021和NEMA CP 1-2000。所有这些设备都适用于交流系统。这些熔断器可与电容器单元、单元组或整个组一起使用，包括特定的电容器线路[group]和电容器单元熔断器类型，如下所示: a） 限流熔断器 b） 驱逐引信 c） 限流和熔断器的组合 d） 与a型、b型和c型保险丝一起使用的保险丝支架、保险丝座和附件） e） 限流型、喷射型和组合型电容器熔断器[分别为a型、b型和C型]），用于熔断器外壳组件（FEP）

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 kV, for protecting shunt capacitors complying with IEEE Std 18?-20021 and 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 follows: a) Current-limiting fuses b) Expulsion fuses c) Combination of current-limiting and expulsion fuses d) Fuse supports, fuse mountings, and accessories used with fuses of type a), type b), and type c) e) Current-limiting, expulsion, and combination-type capacitor fuses [type a), type b), and type C), respectively] used in fuse enclosure packages (FEPs)
