適用范圍：These supplementary requirements apply to fuse-links for protecting PV strings and PV arraysin equipment for circuits of nominal voltages up to 1 500 V d.c.Their rated voltage may be up to 1 500 V d.c.NOTE 1 Such fuse-Iinks are commonly referred to as “PV fuse-links”.NOTE 2 In most cases, a part of the associated equipment serves the purpose of a fuse-base. Owing to the greatvariety of equipment, no general rules can be given; the suitability of the associated equipment to serve as a fusebaseshould be subject to agreement between the manufacturer and the user. However, if separate fuse-bases orfuse-holders are used, they should comply with the appropriate requirements of IEC 60269 series.NOTE 3 PV fuse-links protect down stream inverter components such as capacitors or the discharge of capacitorsback into the arrays or array wiring up to the rated breaking capacity.The object of these supplementary requirements is to establish the characteristics of PV fuselinksin such a way that they can be replaced by other fuse-links having the samecharacteristics, provided that their dimensions are identical. For this purpose, this standardrefers in particular toa) the following characteristics of fuses:1) their rated values;2) their utilisation category;3) their temperature rises in normal service;4) their power dissipation;4) their time-current characteristics;6) their breaking capacity;7) their dimensions or size (if applicable).b) type tests for verification of the characteristics of fuses;c) the markings on fuses.
