適用范圍：1.1 This standard (Part I) applies to all types of high-voltage current-limiting fuses designed for use outdoors or indoors on alternating current systems of 50 Hz and of rated voltages exceeding 1000 V.1.2 Some fuses are provided with fuse-links equipped with an indicating device or a striker. These fuses come within the scope of this standard, but the correct operation of the striker in combination with the tripping device of the switching device for which separate or additional requirements have to be complied with is outside the scope of this standard.Note — This standard refers primarily to three-phase systems with earthed neutral. For applications on single-phase systems or three-phase systems with unearthed neutral, see Part III of this standard.1.3 Fuses designed for the protection of single capacitor units within multi-unit capacitor banks may have to conform to additional requirements other than those specified in this standard.1.4 Fuses complying with the standard are to be operated under the normal conditions of service as detailed in Appendix B.
